Factores asociados al desenlace en niños con mal rotación intestinal manejados en el Hospital Infantil de San Vicente Fundación, Medellín, Colombia / Factors associated with outcome in children with intestinal malrotation managed at the Hospital Infantil of San Vicente Fundación, Medellín, Colombia

Introducción. El intestino primitivo rota durante la vida embrionaria. Cuando ocurre de forma inadecuada aparece la malrotación intestinal que puede llevar a la obstrucción o al vólvulo del intestino medio. La incidencia disminuye con el aumento de la edad. La malrotación intestinal es una de las principales causas de complicaciones del tracto gastrointestinal en la edad pediátrica. Métodos. Estudio retrospectivo, observacional, transversal y analítico, de la experiencia durante 10 años en pacientes menores de 15 años con diagnóstico de malrotación intestinal, tratados en el Hospital Infantil de San Vicente Fundación, en Medellín, Colombia. Se buscó la asociación entre variables demográficas, clínicas e imagenológicas con los desenlaces. Resultados. Se obtuvieron 58 pacientes con malrotación intestinal, 65 % menores de 1 año. En 29,3 % de los pacientes se hizo el diagnóstico con la presentación clínica; los síntomas predominantes fueron distensión abdominal y emesis. En el 24,1 % se confirmó el diagnóstico con imágenes. Las variables con una diferencia estadísticamente significativa a favor de encontrar una malrotación complicada fueron choque séptico (OR=11,7), síndrome de respuesta inflamatoria sistémica (OR=8,4) y deshidratación (OR=5,18). Conclusiones. La malrotación intestinal tiene complicaciones como perforación, peritonitis, vólvulo e intestino corto. El vólvulo se acompaña de shock y sepsis, con mortalidad hasta del 50 %. Las imágenes diagnósticas son una ayuda, pero no se puede basar la conducta médica en estas porque ninguna imagen garantiza el diagnóstico definitivo. Los signos de alarma son poco específicos. En menores de un año con emesis, distensión y dolor abdominal se debe sospechar malrotación intestinal.

Introduction. The primitive intestine rotates during embryonic life. When it occurs inappropriately, intestinal malrotation appears, which can lead to obstruction or midgut volvulus. The incidence decreases when age increases. Intestinal malrotation is one of the main causes of complications of the gastrointestinal tract in pediatric age. Method. Retrospective, observational, cross-sectional and analytical study of the experience over 10 years in patients under 15 years of age with a diagnosis of intestinal malrotation, treated at Hospital Infantil of San Vicente Fundación, in Medellín, Colombia. The association between demographic, clinical and imaging variables with the outcomes was sought. Results. There were 58 patients with intestinal malrotation, 65% under one year of age. In 29.3% of patients, intestinal malrotation was diagnosed clinically. The predominant symptoms were abdominal distension and emesis. In 24.1% the diagnosis was confirmed with imaging. The variables with a statistically significant difference in favor of finding a complicated malrotation were septic shock (OR=11.7), systemic inflammatory response syndrome (OR-8.4), and dehydration (OR=5.18). Conclusions. Malrotation has complications such as perforation, peritonitis, volvulus, and short bowel. Volvulus is accompanied by shock and sepsis, with mortality of up to 50%. Diagnostic images are helpful, but medical conduct cannot be based on them because no image guarantees a definitive diagnosis. The warning signs are not very specific. In children under one year of age with emesis, distension and abdominal pain, intestinal malrotation should be suspected.

Fascitis necrosante como causa de muerte en trauma de recto. Reporte de caso / Necrotizing fasciitis as a cause of death in rectal trauma. Case report

Introducción. La perforación del recto por trauma cerrado es poco frecuente y se asocia a fracturas pélvicas. En pacientes con perforaciones de recto no traumáticas se ha reportado fascitis necrosante en miembros inferiores, en la mayoría de los casos asociada a alta mortalidad. Caso clínico. Hombre de 36 años con trauma cerrado abdomino-pélvico y perforación de recto inferior, quien recibió manejo quirúrgico mediante derivación intestinal y fijación pélvica. Evolucionó con hematoma escrotal sobreinfectado, inestabilidad hemodinámica, signos de fascitis necrosante y choque séptico 4 días posterior a su ingreso. Resultados. Se tomó muestra para cultivo del hematoma escrotal que reportó E. coli. La patología del desbridamiento escrotal informó necrosis de coagulación en toda la muestra. Conclusión. El tacto rectal debe realizarse siempre ante la presencia de enfisema subcutáneo al examen físico o en la tomografía, para un diagnóstico temprano y manejo quirúrgico multidisciplinario oportuno, según el caso. La presencia de enfisema subcutáneo debe aumentar la sospecha de perforación de recto. Hay pocos reportes de fascitis secundaria a perforación de recto por trauma cerrado, por lo que no se conoce con precisión la mortalidad asociada.

Introduction. Rectal perforation due to blunt trauma is rare and associated with pelvic fractures. Signs of necrotizing fasciitis in lower limbs have been reported in non-traumatic rectal perforations, in most cases associated with high mortality. Case report. A 36-year-old man presents blunt abdomino-pelvic trauma and perforation of the lower rectum. Surgical management by intestinal diversion and pelvic fixation is performed. 4 days after admission, evolves with over-infected scrotal hematoma, hemodynamic instability, signs of necrotizing fasciitis and septic shock. Results. A sample for culture was taken from a scrotal hematoma that reported E. coli. Pathology of scrotal debridement reported coagulation necrosis in the entire specimen. Discussion. Digital rectal examination should always be performed in the presence of subcutaneous emphysema on physical examination or CT scan for early and multidisciplinary diagnosis and surgical management as appropriate. Conclusion. The presence of subcutaneous emphysema should raise the suspicion of rectal perforation. There are few reports of rectal perforation due to blunt trauma and fasciitis, so the associated mortality is not precisely known.

Assessment of risk factors for leakage after repair of perforated peptic ulcer with omental patch. Retrospective study / Evaluación de factores de riesgo de fuga después de la reparación de una úlcera péptica perforada con parche de epiplón. Estudio retrospectivo

Introduction. Perforated peptic ulcer remains one of the critical abdominal conditions that requires early surgical intervention. Leakage after omental patch repair represents one of the devastating complications that increase morbidity and mortality. Our study aimed to assess risk factors and early predictors for incidence of leakage. Methods. Retrospective analysis of data of the patients who underwent omental patch repair for perforated peptic ulcer in the period between January 2019 and January 2022 in Mansoura University Hospital, Egypt. Pre, intra and postoperative variables were collected and statistically analyzed. Incriminated risk factors for leakage incidence were analyzed using univariate and multivariate analysis. Results. This study included 123 patients who met inclusion criteria. Leakage was detected in seven (5.7%) patients. Although associated comorbidities (p=0.01), postoperative intensive care unit admission (p=0.03), and postoperative hypotension (p=0.02) were significant risk factors in univariate analysis, septic shock (p=0.001), delayed intervention (p=0.04), preoperative hypoalbuminemia (p=0.017), and perforation size >5mm (p= 0.04) were found as independent risk factors for leakage upon multivariate analysis. Conclusion. Delayed presentation in septic shock, preoperative hypoalbuminemia, prolonged perforation, operation interval, and large perforation size > 5mm were detected as independent risk factors for leakage. Postoperative tachypnea and tachycardia with increased levels of C-reactive protein and total leucocytic count are alarming signs for incidence of leakage

Introducción. La úlcera péptica perforada es una de las afecciones abdominales críticas que requiere una intervención quirúrgica temprana. La fuga después de la reparación con parche de epiplón representa una de las complicaciones más devastadoras, que aumentan la morbilidad y la mortalidad. Nuestro estudio tuvo como objetivo evaluar los factores de riesgo y los predictores tempranos de fugas. Métodos. Análisis retrospectivo de los datos de los pacientes sometidos a reparación con parche de epiplón por úlcera péptica perforada, en el período comprendido entre enero de 2019 y enero de 2022, en el Hospital Universitario de Mansoura, Egipto. Se recogieron y analizaron estadísticamente variables pre, intra y postoperatorias. Los factores de riesgo asociados a la incidencia de fugas se analizaron mediante análisis univariado y multivariado. Resultados. Este estudio incluyó 123 pacientes que cumplieron con los criterios de inclusión. Se detectó fuga en siete (5,7 %) pacientes. Aunque las comorbilidades asociadas (p=0,01), el ingreso postoperatorio a la unidad de cuidados intensivos (p=0,03) y la hipotensión postoperatoria (p=0,02) fueron factores de riesgo en el análisis univariado, el shock séptico (p=0,001), el retraso en la intervención (p=0,04), la hipoalbuminemia preoperatoria (p=0,017) y el tamaño de la perforación mayor de 5 mm (p=0,04) se encontraron como factores de riesgo de fuga independientes en el análisis multivariado. Conclusión. Se detectaron como factores de riesgo independientes de fuga la presentación tardía en shock séptico, la hipoalbuminemia preoperatoria, la perforación prolongada, el intervalo operatorio y el tamaño de la perforación mayor de 5 mm. La taquipnea posoperatoria y la taquicardia con niveles elevados de proteína C reactiva y recuento leucocitario total son signos de alarma sobre la presencia de fuga.

Perforación colónica por endoprótesis biliar impactada / Colonic perforation due to impacted biliary stent

Introducción. La colocación de endoprótesis biliares es cada día más frecuente por ser actualmente una de las mejores opciones para el tratamiento de patologías de la vía biliar. La migración de las endoprótesis es una de las complicaciones que puede ocurrir en hasta un 10,8 % de los pacientes, pero en muy raras ocasiones llegan a causar una perforación intestinal. Caso clínico. Se trata de una paciente de 61 años, a quien cinco años atrás se le realizó una colangiopancreatografía retrógrada endoscópica por coledocolitiasis. Consultó por presentar dolor abdominal, y al examen físico se encontraron abdomen agudo y plastrón en fosa ilíaca izquierda a la palpación. La tomografía computarizada informó un cuerpo extraño a nivel del colon descendente, con perforación del mismo. Se realizó laparotomía exploratoria y colostomía por perforación del colon sigmoides secundaria a prótesis biliar migrada. Resultados. La paciente evolucionó favorablemente y a los seis meses se realizó el cierre de la colostomía, sin complicaciones. Conclusión. Los pacientes a quienes se les colocan prótesis biliares requieren un seguimiento adecuado para evitar complicaciones que, aunque raras, pueden ocurrir, como la migración intestinal con perforación. El tratamiento de dichas complicaciones se hace por vía endoscópica, laparoscópica o laparotomía en caso de complicación severa.

Introduction. Endoscopic placement of biliary stents is becoming more common every day, as it is currently one of the best options for the treatment of bile duct pathologies. One of the complications that can occur is the migration of the endoprostheses in up to 10.8% of patients, which in very rare cases can cause intestinal perforation. Clinical case. This is a 61-year-old female patient, who underwent endoscopic retrograde cholangiopancreatography five years ago for choledocholithiasis. She consulted due to abdominal pain, with a physical examination that upon palpation documented an acute abdomen and a palpable plastron in the left iliac fossa. The computed tomography revealed a foreign body at the level of the descending colon, with perforation. Exploratory laparotomy and colostomy were performed due to perforation of the sigmoid colon secondary to migrated biliary prosthesis. Results. The patient progressed favorably and six months later the colostomy was closed without complications. Conclusions. Patients who receive biliary stents require adequate follow-up to avoid complications that, although rare, may occur, such as intestinal migration with intestinal perforation. The treatment of these complications can be endoscopic, laparoscopic or laparotomy in case of severe complication.

Preoperative promestriene for hysteroscopy: a randomized clinical trial

SUMMARY OBJECTIVE: Intraoperative complications of hysteroscopy, such as the creation of a false passage, cervix dilatation failure, and uterine perforation, may require suspension of the procedure. Some patients refuse a new procedure, which delays the diagnosis of a possible serious uterine pathology. For this reason, it is essential to develop strategies to increase the success rate of hysteroscopy. Some authors suggest preoperative use of topical estrogen for postmenopausal patients. This strategy is common in clinical practice, but studies demonstrating its effectiveness are scarce. The aim of this study was to evaluate the effect of cervical preparation with promestriene on the incidence of complications in postmenopausal women undergoing surgical hysteroscopy. METHODS: This is a double-blind clinical trial involving 37 postmenopausal patients undergoing surgical hysteroscopy. Participants used promestriene or placebo vaginally daily for 2 weeks and then twice a week for another 2 weeks until surgery. RESULTS: There were 2 out of 14 (14.3%) participants with complications in the promestriene group and 4 out of 23 (17.4%) participants in the placebo group (p=0.593). The complications were difficult cervical dilation, cervical laceration, and vaginal laceration. CONCLUSION: Cervical preparation with promestriene did not reduce intraoperative complications in postmenopausal patients undergoing surgical hysteroscopy.

Wet bio-amniotic membrane plugging combined with transplantation in the treatment of small corneal perforations

ABSTRACT Purpose: Wet bio-amniotic membrane plugging combined with transplantation is a novel option that combined amniotic membrane plugging with amniotic membrane transplantation for the treatment of small corneal perforations. This study aimed to evaluate the efficacy of wet bio-amniotic membrane plugging in the treatment of small corneal perforations and compared it with that of the penetrating keratoplasty procedure. Methods: Forty patients (41 eyes) with small corneal perforations <3 mm in diameter treated at our hospital between July 2018 and January 2021 were retrospectively included. Among them, 21 eyes were treated with wet bio-amniotic membrane plugging (wet bio-amniotic membrane plugging group), and 20 eyes were treated with penetrating keratoplasty procedure (penetrating keratoplasty procedure group). The best-corrected visual acuity, anterior chamber formation, corneal thickness, primary disease control, postoperative complications, and graft survival rate were assessed. Results: No significant difference in baseline characteristics was found between the wet bio-amniotic membrane plugging and penetrating keratoplasty procedure groups (p>0.05). The postoperative control rates of primary diseases in the wet bio-amniotic membrane plugging and penetrating keratoplasty procedure groups were 95.2% and 90.0%, respectively (p=0.481). Visual acuity was improved 6 months after the operation in the wet bio-amniotic membrane plugging group and was improved at postoperative 1 month in the penetrating keratoplasty procedure group. The formation time of the anterior chamber in the wet bio-amniotic membrane plugging group was significantly shorter than that in the penetrating keratoplasty procedure group (p=0.023). The corneal thickness of the two groups significantly increased 12 months after the operation; however, the degree of thickening in the penetrating keratoplasty procedure group was higher than that in the wet bio-amniotic membrane plugging group (p<0.001). During the follow-up, postoperative complications were not different between the two groups (p>0.999). Conclusion: The results suggest that wet bio-amniotic membrane plugging is effective and safe in the treatment of small corneal perforations. Thus, it can be used as an emergency treatment alternative to penetrating keratoplasty procedure for small corneal perforations.

Diagnostic accuracy of the video otoscope in tympanic membrane perforation

Abstract Objective The video otoscope has already proven to be useful for the diagnosis of several pathologies, so the objective of this study was to evaluate the diagnostic accuracy of the video otoscope in cases of tympanic membrane perforation. Methods This is a diagnostic accuracy study performed at the hearing health division of a tertiary-level referral hospital. Patients older than 8 years of age who had any symptom that could be related to perforation (otalgia, otorrhea, tinnitus, and/or hypoacusis) were invited to participate in the study. Participants were evaluated by three different diagnostic methods (otomicroscope, conventional otoscope, and video otoscope) performed by three different evaluators in a blind fashion. The microscope was considered the reference standard. Results 176 patients were evaluated, totaling 352 tympanic membranes. Twenty-seven tympanic membrane perforations were diagnosed by the microscope, a prevalence of 7.7%. The video otoscope showed a sensitivity of 85.2% (95% CI 81.5%‒88.9%), specificity of 98.1% (95% CI 96.7%‒99.5%) and accuracy of 97.1% (95% CI 95.4 %-98.8 %). The conventional otoscope showed a sensitivity of 96.3% (95% CI 94.3-98.3), specificity of 98.8% (95% CI 97.7-99.9) and accuracy of 98.6% (95% CI 97.4-99.8). The Kappa value between the microscope and the video otoscope was 0.8 and between the microscope and the conventional otoscope was 0.9. Regarding the participants' perception, 53.4% (p < 0.001) considered the video otoscope as the best method for understanding the tympanic membrane condition presented by them. Conclusions The video otoscope showed relevant sensitivity and specificity for clinical practice in the diagnosis of tympanic membrane perforation. Moreover, this is an equipment that can facilitate the patient's understanding of the otologic pathology presented by him/her. In this regard, this method may be important for better patient compliance, requiring further studies to evaluate this hypothesis. Level of evidence Is this diagnostic or monitoring test accurate? (Diagnosis)—Level 2 (Individual cross-sectional studies with consistently applied reference standard and blinding).

Tratamento de perfuração iatrogênica de furca com técnica de inserção modificada do mta: relato de caso / Iatrogenic furca perforation treatment with modified mta insertion technique: case report

As perfurações endodônticas podem ocorrer patologicamente por lesão cariosa profunda, bem como durante o acesso ou na instrumentação dos canais radiculares, que em sua grande maioria estão relacionadas com a negligência ou desconhecimento das variações anatômicas internas do dente. O presente trabalho descreve um caso clínico de perfuração de furca, onde o tratamento inicial foi baseado na descontaminação e selamento da comunicação com uma técnica de inserção modificada do MTA. Após a anestesia, foi realizado o isolamento absoluto e remoção de tecido infectado presente na câmara pulpar. Feita a limpeza da perfuração utilizando soro fisiológico e modelagem do canal com o instrumento reciprocante, a obturação foi concebida com cone de guta percha e cimento biocerâmico. Em seguida, o MTA foi manipulado, de acordo com recomendações do fabricante usando água destilada na proporção 1:1 e inserido na canaleta de uma régua endodôntica com a espátula de inserção nº1. O material foi removido da canaleta e inserido na perfuração, finalizando o vedamento da mesma. Portanto, concluiu-se que o selamento da perfuração apresentou um resultado satisfatório, tanto clínico como radiográfico, destacado pela proservação de 5 meses, evidenciando discreta formação de trabeculado ósseo na região de furca(AU)

Endodontic perforations can occur pathologically due to a deep carious lesion, as well as during access or instrumentation of root canals, which are mostly related to negligence or ignorance of the internal anatomical variations of the tooth. The present work describes a clinical case of furcation perforation, where the initial treatment was based on decontamination and sealing of the communication with a modified MTA insertion technique. After anesthesia, absolute isolation and removal of infected tissue present in the pulp chamber was performed. After cleaning the perforation using saline solution and modeling the canal with the reciprocating instrument, the filling was designed with a gutta-percha cone and bioceramic cement. Then, the MTA was manipulated, according to the manufacturer's recommendations, using distilled water in a 1:1 ratio and inserted into the groove of an endodontic ruler with the #1 insertion spatula. The material was removed from the channel and inserted into the perforation, finishing its sealing. Therefore, it was concluded that the sealing of the perforation presented a satisfactory result, both clinical and radiographic, highlighted by the 5-month followup, evidencing a slight formation of bone trabeculate in the furcation region(AU)

Síndrome de Rapunzel asociado a perforación intestinal. Caso clínico / Rapunzel syndrome associated with intestinal perforation. Clinical case

Introducción. Los tricobezoares ocurren de forma frecuente en niñas y adolescentes, y se asocian a trastornos psicológicos como depresión, tricotilomanía o tricofagia. Caso clínico. Se presenta una paciente adolescente con síndrome de Rapunzel, con hallazgo adicional de perforación yeyunal debido al tricobezoar. Discusión. Dentro de las complicaciones de los tricobezoares se reporta invaginación intestinal (principalmente de yeyuno), apendicitis, obstrucción biliar, neumonía, pancreatitis secundaria y perforación, esta última como ocurrió en nuestra paciente. Conclusión. En pacientes mujeres adolescentes con dolor abdominal o abdomen agudo, se debe tener en cuenta el diagnóstico de síndrome de Rapunzel, así como sus probables complicaciones

Introduction. Trichobezoars occur frequently in young and adolescent girls, and are associated with psychological disorders such as depression, trichotillomania, or trichophagia. Clinical case. An adolescent patient with Rapunzel syndrome is presented, with an additional finding of jejunal perforation due to the trichobezoar. Discussion. Among the complications of trichobezoars, intussusception is reported (mainly of the jejunum), appendicitis, biliary obstruction, pneumonia, secondary pancreatitis, and perforation, the latter as occurred in our patient. Conclusion. In adolescent female patients with abdominal pain or acute abdomen, the diagnosis of Rapunzel syndrome should be taken into account, as well as its probable complications

Perforación gástrica neonatal recurrente: Reporte de un caso inusual

La perforación gástrica neonatal es una patología rara pero potencialmente mortal; su recurrencia es aún más rara, son escasos los reportes en la literatura internacional. Se presenta el caso de una recién nacida prematura (32 semanas) y bajo peso al nacer (1725g) que el primer día de vida presentó una perforación gástrica corregida quirúrgicamente y al cuarto día postoperatorio es reintervenida con presunción diagnóstica de dehiscencia de rafía gástrica, hallándose una nueva perforación gástrica, la cual fue reparada quirúrgicamente. En ambas ocasiones la intervención quirúrgica fue temprana. La evolución posterior y desenlace fueron favorables.

Neonatal gastric perforation is a rare but potentially fatal pathology; its recurrence is even more infrequent, and there are few reports in the international literature. We present the case of a premature newborn (32 weeks) and low birth weight (1725g) who, on the first day of life, presented a surgically corrected gastric perforation and on the fourth postoperative day was re-operated with a presumed diagnosis of gastric raffia dehiscence, finding a new gastric perforation, which was surgically repaired. On both occasions, the surgical intervention was early. The subsequent evolution and outcome were favorable.

Early Results of Type I Tympanoplasty in Underprivileged Nepalese Children and Factors Influencing the Surgical Outcomes

Abstract Introduction Type I Tympanoplasty is a common ear surgery performed in Nepalese children, but no studies have been published about the success rate of the procedure and the factors affecting surgical outcomes. Objectives To find out the surgical outcome of type I tympanoplasty and to evaluate the factors affecting the success of the surgery in Nepalese children. Methods This is a retrospective study conducted by analyzing the medical records of a five-year period. Children aged 8-16 years who underwent type I tympanoplasty were included in the study. Surgical pro-forma and records of pre and post-operative pure tone audiometry were documented. Outcome of the surgery was considered a success in terms of graft uptake and hearing improvement six months after surgery. Results Out of 629 children who underwent type I tympanoplasty, anatomical success was observed in 93.32% (n = 587) and functional success in 76% (n = 478). Factors such as age, site and size of the perforation, status of the middle ear and contralateral ear, surgical approach, and the graft used were not the predictors of the surgical outcome. Conclusions The surgical outcome of type I tympanoplasty in Nepalese children was good. Although surgical outcome was better with older children, post-aural approach, temporalis fascia, inferiorly positioned perforations, and in children with dry middle ear mucosa, none of the parameters considered in this study were found to be a significant predictive factor of the surgical outcome.

Manejo de perforaciones, fugas y fístulas del tracto gastrointestinal con clip sobre el endoscopio. Experiencia de un centro oncológico Latinoamericano / Management of perforations, leaks and fistulas of the gastrointestinal tract with over the scope clip. Experience at a Latin American cancer center

Introducción. Las fístulas derivadas de enfermedades neoplásicas del tracto digestivo, así como las fugas posteriores a procedimientos quirúrgicos, no son infrecuentes y ocasionan una morbilidad importante cuando se manejan de forma quirúrgica. También durante los procedimientos endoscópicos se pueden presentar perforaciones y, si se logra un manejo no operatorio, se alcanza una adecuada recuperación. El objetivo de este estudio fue describir las características clínicas y los resultados de los pacientes con perforaciones, fístulas y fugas del tracto gastrointestinal, manejadas endoscópicamente con clip sobre el endoscopio. Métodos. Estudio descriptivo, retrospectivo, de pacientes con perforación, fuga o fístula postoperatoria, llevados a endoscopía digestiva con colocación de clip sobre el endoscopio, en el Instituto Nacional de Cancerología en Bogotá, D.C., Colombia, entre enero de 2016 y abril de 2020. Resultados. Se incluyeron 21 pacientes, 52,4 % de ellos mujeres. La mediana de edad fue de 66 años y del diámetro del defecto fue de 9 mm. En el 95 % se logró éxito técnico. Hubo éxito clínico temprano en el 85,7 % de los casos. El 76,1 % de los pacientes permanecieron sin síntomas a los 3 meses de seguimiento. Conclusiones. El manejo de perforaciones, fugas y fístulas con clip sobre el endoscopio parece ser factible y seguro. En la mayoría de estos pacientes se logró la liberación del clip y la identificación endoscópica del cierre inmediatamente después del procedimiento; sin embargo, en el caso de las fístulas, no se alcanzó el éxito clínico tardío en todos los casos

Introduction. Fistula of the digestive tract derived from neoplastic diseases as well as leaks following surgical procedures are not uncommon and usually cause significant morbidity when are managed surgically. Diagnostic and therapeutic endoscopic procedures may present perforations during their performance; if they are managed non-operatively, an adequate recovery is obtained. The purpose of this study was to describe the clinical characteristics and the short- and long-term outcomes of patients with perforations, fistulas and leaks of the gastrointestinal tract managed endoscopically with over the scope clip (OTSC). Methods. Descriptive, retrospective study of patients brought to digestive endoscopy with OTSC placement with diagnosis of postoperative perforation, leak or fistula at the National Cancer Institute in Bogota, Colombia, between January 2016 and April 2020. Results. Twenty-one patients were taken for OTSC application for the management of perforations, leaks and fistulas of the gastrointestinal tract, 52.4% of them were women. The median age was 66 years. The median diameter of the defect was 9 mm. Technical success was achieved in 95%. Early clinical success was described in 85.7% of the cases; 76.1% of patients remained symptom-free at 3-month follow-up. Conclusions. Management of perforations, leaks and fistulas with OTSC appears to be feasible and safe. In most of these patients, clip release and endoscopic identification of closure was achieved immediately after management; however, in the case of fistulas, late clinical success was not achieved in all cases

Corneal Perforation associated with "Silent Brain Syndrome" / Perfuração corneana associada à "síndrome do cérebro silencioso"

ABSTRACT This case report describes the clinical characteristics and ophthalmic management of a patient who developed corneal perforation due to severe enophthalmos consistent with "silent brain syndrome." A 27-year-old man with a history of congenital hydrocephalus and ventriculoperitoneal shunt was referred with complaints of "sinking of the eyeballs" and progressively decreasing vision in the left eye. Examination revealed severe bilateral enophthalmos in addition to superonasal corneal perforation with iris prolapse in the left eye. The patient underwent therapeutic keratoplasty the next day. Orbital reconstruction with costochondral graft and shunt revision of the intracranial hypotension were performed the next month to prevent further progression.

RESUMO Este relato de caso descreve as características clínicas e o manejo cirúrgico de um paciente que teve perfuração da córnea devido à enoftalmia grave consistente com a "síndrome do cérebro silencioso". Um homem de 27 anos com história de hidrocefalia congênita e derivação ventrículo-peritoneal foi encaminhado com queixas de "afundamento dos globos oculares" e diminuição progressiva da visão no olho esquerdo. O exame revelou enoftalmo bilateral importante, além de perfuração superonasal da córnea com prolapso iriano no olho esquerdo. A paciente foi submetida à ceratoplastia terapêutica no dia seguinte. Foi realizado no mês seguinte a reconstrução da órbita com enxerto costocondral e revisão do shunt para evitar progressão e piora do caso.

Impact of the coronavirus disease 2019 pandemic on the management of acute peptic ulcer perforation: to be reconsidered(?)

SUMMARY OBJECTIVE: Peptic ulcer perforation presents the most serious complication of ulcer disease with mortality that varies significantly depending on the age and conditions. The coronavirus disease 2019 pandemic was effective worldwide in 2020 and continues to date. The aim of this study was to investigate the initial clinical parameters and short-term outcomes of patients with acute peptic ulcer perforation before and during the coronavirus disease 2019 pandemic. METHODS: A retrospective cohort study was conducted in the Department of Surgery, University Hospital Ostrava, Czech Republic. The patients undergoing surgical modality of a simple suture of peptic ulcer perforation with/without omentoplasty in the post-coronavirus disease 2019 (January 1, 2020 to December 31, 2021) and the pre-coronavirus disease 2019 (January 1, 2018 to December 31, 2019) had been incorporated in this study. RESULTS: This study included a total of 46 cases (26 in the pre-coronavirus disease 2019, 20 in the post-coronavirus disease 2019). The age, body mass index, Boey score, duration of symptoms, surgery time, and length of hospital stay were comparable in both study subgroups. During the coronavirus disease 2019 pandemic, patients were admitted with a statistically significantly lower degree of perioperative risk according to the American Society of Anesthesiologists classification (p=0.013). Notably, 30-day postoperative morbidity was significantly higher in pre-coronavirus disease 2019 (73.1 vs. 55.0%, p=0.038). The mortality rate in the laparoscopic group was 13.6%, in the laparotomy group 41.4%, and the mortality rate was higher in pre-coronavirus disease 2019 than in post-coronavirus disease 2019 (34.6 vs. 20.0%, p=0.166). CONCLUSION: In fact, the coronavirus disease 2019 pandemic had not significantly influenced therapeutic management and short-term outcomes of patients undergoing acute surgical repair of peptic ulcer perforation.

Perforación cecal por angiostrongiliasis en un adulto mayor / Cecal perforation due to angiostrongyliasis in an elderly patient

La angiostrongiliasis abdominal es una enfermedad parasitaria causada por el género Angiostrongylus costaricensis, un nematodo que infecta a los humanos a través de las secreciones de caracoles o babosas, sus huéspedes definitivos. Costa Rica es el país que se considera más endémico, se ha evidenciado en distintas revisiones que la mayoría de los casos se presentan en niños y personas del sexo masculino. Presentación del caso. Se trata de una mujer de 74 años, que consultó por dolor abdominal agudo, de cuatro días de evolución, acompañado de náuseas, vómitos e hiporexia. Los exámenes de laboratorio reportaron leucocitosis leve y examen general de orina negativo. La ultrasonografía abdominal reportó una masa sólida, heterogénea, mal circunscrita en flanco derecho, esto llevó a la sospecha de una apendicitis aguda. Intervención terapéutica. Se realizó una laparotomía exploradora, con la extirpación de una tumoración de colon perforado que abarcaba desde el ciego hasta el tercio proximal de colon ascendente, además, se realizó una anastomosis de íleo transversa, sin mayor complicación. Evolución clínica. Se manejó con antibióticos y analgésicos, fue dada de alta a los nueve días posteriores al procedimiento, sin complicaciones menores. La biopsia reportó huevos de parásitos consistentes con Angiostrongylus sp

bdominal angiostrongyliasis is a parasitic disease caused by the genus Angiostrongylus costaricensis, a nematode that infects humans through the secretions of snails or slugs, its definitive hosts. Costa Rica is considered the most endemic country, and it has been shown in different reviews that most cases occur in children and males. Case presentation. The patient was a 74-year-old woman who consulted for acute abdominal pain, with four days of evolution, accompanied by nausea, vomiting, and hyporexia. Laboratory tests reported mild leukocytosis and a negative general urine test. Abdominal ultrasonography reported a solid heterogeneous mass, poorly circumscribed in the right lateral abdomen, which led to the suspicion of acute appendicitis. Treatment. An exploratory laparotomy was performed, with the removal of a perforated colon tumor that spanned from the cecum to the proximal third of the ascending colon, in addition, a transverse ileum anastomosis was performed, without further complication. Outcome. She was managed with antibiotics and analgesics and was discharged nine days after the procedure, without complications. The biopsy showed parasite eggs consistent with Angiostrongylus sp

Tratamiento quirúrgico inmediato en niños con perforación espontánea de la vía biliar. Experiencias de 16 años

Introducción: La perforación espontánea de los conductos biliares es una rara enfermedad caracterizada por una disrupción no traumática de la vía biliar en pacientes aparentemente sanos. Se trata de una grave situación potencialmente letal, pero diagnosticada y tratada correctamente tiene un pronóstico excelente. Objetivo: Caracterizar los principales elementos clínico-quirúrgicos expresados en una serie de 5 pacientes operados en un servicio de referencia nacional. Presentación de casos: Se presenta la experiencia con una serie de casos en 16 años en una sola institución. La afección se observó en niñas recién nacidas y lactantes con una edad media de 4 meses, y se presentó desde la clínica como una colestasis acompañada de distensión abdominal, ascitis biliar, acolia, y signos de irritación peritoneal. El 80 % de los casos se intervinieron en el hospital "William Soler", y en un caso se ejecutó el procedimiento después de una laparotomía por una posible apendicitis aguda, en otro hospital. El diagnóstico se basó en el cuadro clínico descrito, la ecografía abdominal, la paracentesis con medición del índice bilirrubina líquido ascítico/bilirrubina sérica, y la colangiografía intraoperatoria. La cirugía definitiva se realizó inmediatamente, y consistió en: lavado peritoneal, colangiografía diagnóstica, reparación hepaticoyeyunostomía en Y de Roux y colocación de drenaje. Conclusiones: El tratamiento realizado resulta eficaz y seguro en todos los casos, con una excelente evolución, sin complicaciones importantes y con una total supervivencia posoperatoria. La colangiografía intraoperatoria permitió identificar el sitio de la perforación y diagnosticar malformaciones asociadas como dilataciones biliares congénitas y anomalías de la unión bilio-pancreática.

Introduction: Spontaneous bile duct perforation is a rare condition characterized by non-traumatic disruption of the bile duct in apparently healthy patients. It is a serious potentially lethal situation, but correctly diagnosed and treated its prognosis is excellent. Objetive: To characterize the main clinical-surgical elements expressed in a series of 5 patients operated in a national referral service. Case presentation: The experience with a series of cases during a period of 16 years in a single institution is presented. The condition was observed mainly in newborn girls and infants with an average age of 4 months, and presented clinically as cholestasis accompanied by abdominal distension, biliary ascites, acholia, and signs of peritoneal irritation. 80% of the cases were operated primarily in the "William Soler" hospital, and in one case the procedure was performed after a laparotomy for a possible acute appendicitis, in another hospital. The diagnosis was based on the clinical picture described, abdominal ultrasound, paracentesis with measurement of the ascitic liquid bilirubin/serum bilirubin index, and intraoperative cholangiography. Definitive surgery was performed immediately and consisted of: peritoneal lavage, diagnostic cholangiography, Roux-en-Y liver and jejunostomy repair and drainage placement. Conclusions: The treatment performed was effective and safe in all cases, with an excellent evolution, no major complications and total postoperative survival. Intraoperative cholangiography made it possible to identify the site of perforation and to diagnose associated malformations such as congenital biliary dilatations and anomalies of the biliary-pancreatic junction.

Avaliação da influência da agitação ultrassônica na resistência de união de dois materiais reparadores utilizados para selar perfurações na furca / Assessment of the influence of ultrasonic agitation on the joint resistance of two repairing materials used to seal perforations in the burning / Evaluación de la influencia de la agitación ultrasónica en la resistencia de la unión de dos materiales de reparación utilizados para sellar otras perforaciones

Avaliou-se a influência da utilização da agitação ultrassônica na resistência de união à dentina, por meio de push-out, proporcionada pelos cimentos MTA-Angelus branco (MTA) e Biodentine (BD), empregados no selamento de perfurações de furca. Foram utilizados 48 primeiros ou segundos molares inferiores, com raízes não fusionadas, distantes cerca de 2 mm entre si na porção cervical das mesmas. Os dentes foram acessados e, em seguida, as raízes foram seccionadas transversalmente abaixo da junção cemento-esmalte. Os dentes foram montados em blocos de silicona de adição e perfurações de furca realizadas em seus assoalhos paralelamente ao longo eixo dos dentes e perpendiculares aos assoalhos dentais. A amostra foi dividida em quatro grupos (n = 12) em função do material reparador e da utilização ou não da agitação ultrassônica (AU). Quando empregada, a AU foi aplicada em 2 ciclos de 20 segundos por meio de inserto cônico liso acionado por ultrassom piezoelétrico. Concluídos os selamentos eles foram protegidos com cimento de ionômero de vidro e os dentes imersos em PBS. Decorridos 7 dias discos com 1 mm de altura foram retirados dos assoalhos dentais com auxílio de cortadora metalográfica e levados à máquina de ensaio universal. Os resultados expressos em MPa foram submetidos aos testes ANOVA dois fatores e de Bonferroni. Os maiores valores de resistência obtidos foram no grupo Biodentine com ultrassom (29,41 MPa), seguidos em ordem decrescente pelos grupos Biodentine sem ultrassom; MTA com ultrassom e MTA sem ultrassom (3,72 MPa). Nas condições do estudo concluiu-se que o BD apresentou maior resistência de união à dentina radicular; ainda, que a agitação ultrassônica influenciou positivamente na resistência de união do material à dentina.

We evaluated the influence of the use of ultrasonic agitation on the resistance to the dentin, by means of push-out, provided by the white MTA-Angelus (MTA) and Biodentine (BD) cements, used in the sealing of drilling holes. 48 first or second lower molars were used, with unfused roots, about 2 mm apart in the cervical portion of them. The teeth were accessed and then the roots were sectioned transversely below the cementenamel junction. The teeth were mounted in addition silicon blocks and hole drills performed on their floors parallel along the axis of the teeth and perpendicular to the dental floorings. The sample was divided into four groups (n = 12) depending on the repair material and whether ultrasonic agitation (AU) was used. When employed, the AU was applied in 2 20-second cycles by means of a smooth conical insert activated by piezoelectric ultrasound. Once the seals were completed, they were protected with glass ionomer cement and the teeth immersed in PBS. After 7 days, 1 mm high disks were removed from the dental floorboards with the aid of a metallographic cutter and taken to the universal test machine. Results expressed in MPa were submitted to two-factor and Bonferroni ANOVA tests. The highest resistance values obtained were in the group Biodentine with ultrasound (29.41 MPa), followed in descending order by the groups Biodentine without ultrasound; MTA with ultrasound and MTA without ultrasound (3.72 MPa). Under the conditions of the study, it was concluded that BD showed greater resistance to root dentin binding; also, that ultrasonic agitation positively influenced the resistance of the material to dentin binding.

influencia del uso de la agitación ultrasónica sobre la resistencia de la unión a la dentina se evaluó mediante un estiramiento, proporcionado por los cementos blancos (MTA) y biodentinos (BD) MTA-Angelus, empleados en el sello de los taladros. Se utilizaron los primeros o segundos molares inferiores, con raíces sin fundir, a unos 2 mm de distancia en la porción cervical de las raíces. Se accedió a los dientes y luego las raíces se seccionaron transversalmente por debajo de la unión cemento-enamel. Los dientes se ensamblaron además bloques de silicona y agujeros de perforación en sus pisos a lo largo del eje de los dientes y perpendiculares al suelo dental. La muestra se dividió en cuatro grupos (n = 12) según el material de reparación y si se utilizó o no la agitación ultrasónica (AU). Cuando se empleó, la UA se aplicó en 2 ciclos de 20 segundos mediante una inserción cónica suave activada por ultrasonido piezoeléctrico. Una vez concluidos los sellos, se protegieron con cemento ionómero de vidrio y los dientes se sumergieron en PBS. Al cabo de 7 días, los discos de 1 mm de altura se retiraron del suelo de corte metálico y se llevaron a la máquina de ensayo universal. Los resultados expresados como MPa se presentaron a las pruebas de dos factores ANOVA y Bonferroni. Los valores de resistencia más altos obtenidos fueron en el grupo de Biodentina con ultrasonido (29,41 MPa), seguidos en orden descendente por los grupos de Biodentina sin ultrasonido; MTA de ultrasonido y MTA libre de ultrasonido (3,72 MPa). En las condiciones del estudio se concluyó que la DB mostró mayor resistencia de la unión a la dentina raíz; y que la agitación ultrasónica tuvo una influencia positiva en la resistencia del material a la dentina.

Acute hydrops followed by corneal perforation five years after corneal cross-linking for keratoconus / Hidropisia aguda seguida de perfuração da córnea cinco anos após reticulação corneana para ceratocone

ABSTRACT We report a case of acute corneal hydrops followed by corneal perforation five years after corneal cross-linking for keratoconus. A healthy 24-year-old female patient underwent Dresden protocol cross-linking in her left eye due to advanced keratoconus. After five years of a stable cornea, she returned with epiphora, blurred vision, and a soft left eye. Acute hydrops and corneal perforation were diagnosed. There was no history of pregnancy, atopy, eye rubbing, trauma, or contact lens use. Local antibiotic and eye patching were applied. Three months after the resolution of the acute episode, she retained useful visual acuity with no need for further surgery. Although cross-linking efficiently halts keratoconus, progression can occur, leading to corneal hydrops and perforation, even in the absence of any risk factors.

RESUMO Este é o relato de um caso de hidropisia aguda seguida de perfuração corneana cinco anos após reticulação corneana para ceratocone. Uma paciente saudável de 24 anos foi submetida a reticulação corneana no olho esquerdo pelo protocolo de Dresden, devido a um ceratocone avançado. Após cinco anos com a córnea estável, a paciente retornou com epífora, visão turva e amolecimento do olho esquerdo. Foram diagnosticadas hidropisia aguda e perfuração corneana. A paciente não tinha história de gravidez, atopia, fricção ocular, trauma ou uso de lentes de contato. Foram aplicados um antibiótico local e um tampão oftalmológico. Três meses após a resolução do episódio agudo, ela manteve uma acuidade visual útil, sem necessidade de novas cirurgias. Embora a reticulação interrompa de forma eficiente o ceratocone, pode ocorrer progressão, levando a hidropisia e perfuração da córnea, mesmo na ausência de fatores de risco.

Impact of the covid-19 pandemic on the emergency surgical treatment of colorectal cancer / Impacto da pandemia da covid-19 no tratamento cirúrgico emergencial do câncer colorretal

ABSTRACT BACKGROUND: Colorectal cancer (CRC) is the most common malignancy of the gastrointestinal tract and the third most common type of cancer worldwide. The COVID-19 pandemic, during the years 2020 and 2022, increased the difficulties in offering adequate early diagnosis and treatment to CRC patients worldwide. During this period, it was only possible to treat patients who evolved with complications, mainly intestinal obstruction and perforation. AIMS: To assess the impact of the COVID-19 pandemic on the treatment of patients with CRC. METHODS: A review of data from a total of 112 patients undergoing emergency surgical treatment due to complications of CRC was carried out. Of these, 78 patients underwent emergency surgery during the COVID-19 pandemic (2020/2021), and 34 were treated before the pandemic (2018/2019). Ethnic aspects, clinical symptoms, laboratory tests, histopathological variables, intra and postoperative complications, and 90-day postoperative follow-up were compared between the two groups. RESULTS: Between the years 2018 and 2019, 79.4% (27/34) of patients had intestinal obstruction, while 20.6% (7/34) had intestinal perforation. During the period of the COVID-19 pandemic (2020/2021), 1.3% (1/78) of patients underwent surgery due to gastrointestinal bleeding, 6.4% (5/78) due to intestinal perforation, and 92.3% (72/78) due to intestinal obstruction. No statistically significant differences were recorded between the two groups in ethnic aspects, laboratory tests, type of complications, number of lymph nodes resected, compromised lymph nodes, TNM staging, pre or intraoperative complications, length of stay, readmission, or mortality rate. When considering postoperative tumor staging, among patients operated on in 2018/2019, 44.1% were classified as stage III and 38.2% as stage IV, while during the pandemic period, 28.2% presented stage III and 51.3% stage IV, also without a statistically significant difference between the two periods. Patients operated on during the pandemic had higher rates of vascular, lymphatic and perineural invasion. CONCLUSIONS: The COVID-19 pandemic increased the rate of complications related to CRC when comparing patients treated before and during the pandemic. Furthermore, it had a negative impact on histopathological variables, causing worse oncological prognoses in patients undergoing emergency surgery.

RESUMO RACIONAL: O câncer colorretal (CCR) é a doença maligna mais comum do trato gastrointestinal sendo o terceiro tipo de câncer mais comum em todo o mundo. A pandemia de COVID-19 durante os anos de 2020 e 2022 aumentou as dificuldades em se oferecer diagnóstico e tratamento precoce adequado aos pacientes com CCR em todo o mundo. Nesse período, só foi possível tratar os pacientes que evoluíram com complicações representadas, principalmente, pela obstrução e perfuração intestinal. OBJETIVOS: Avaliar o impacto da pandemia de COVID-19 no tratamento de pacientes com CCR. MÉTODOS: Foi realizada uma revisão dos dados de um total de 112 pacientes submetidos ao tratamento cirúrgico de urgência devido complicações do CCR. Destes, 78 pacientes foram submetidos a cirurgia de emergência durante o período da pandemia de COVID-19 (2020/2021), e 34 pacientes foram operados no período anterior à pandemia (2018/2019). Aspectos étnicos, sintomas clínicos, exames laboratoriais, variáveis histopatológicas, complicações intra e pós-operatórias e acompanhamento pós-operatório de 90 dias foram analisados comparando os dois grupos. RESULTADOS: Entre os anos 2018 e 2019, 79,4% (27/34) dos pacientes apresentaram obstrução intestinal enquanto 20,6% (7/34) perfuração intestinal. Durante o período da pandemia de COVID-19 (2020/2021) 1,3% (1/78) dos pacientes foram operados por hemorragia digestiva baixa, 6,4% (5/78) por perfuração intestinal e 92,3% (72/78) por obstrução intestinal. Não foram registradas diferenças estatisticamente significativas entre os dois grupos nos aspectos étnicos, exames laboratoriais, tipo de complicações, número de linfonodos ressecados, linfonodos comprometidos, estadiamento TNM, complicações pré ou intraoperatórias, tempo de internação, readmissão e taxa de mortalidade. Ao considerar o estadiamento tumoral pós-operatório, entre os pacientes operados em 2018/19, 44,1% foram classificados como estágio III e 38,2% como estágio IV, enquanto no período pandêmico, 28,2% apresentaram estágio III e 51,3% estágio IV, também sem diferença estatisticamente significativa entre os dois períodos. Doentes operados durante a pandemia apresentaram maiores índices de invasão vascular, linfática e perineural. CONCLUSÕES: A pandemia de COVID-19 aumentou as taxas de complicações relacionadas ao CCR, comparando pacientes tratados antes e durante a pandemia. Além disso, teve impacto negativo nas variáveis histopatológicas, causando piores prognósticos oncológicos em pacientes submetidos a cirurgias de emergência.
