Jejunal Perforation Due to Histoplasmosis Regarding a Case.

Histoplasmosis is an increasing infection that mainly affects immunocompromised individuals such as patients with HIV/AIDS, with the disseminated form, especially gastrointestinal, being common in this population. The clinical presentation ranges from asymptomatic to symptoms that mimic other abdominal diseases. Jejunal perforation due to histoplasmosis, although rare, has been reported in a few cases, typically in men living with HIV in their fourth decade of life. We present the case of a 34-year-old male, with a history of HIV and colonic histoplasmosis who presented with acute abdominal pain requiring exploratory laparotomy and intestinal resection due to jejunal perforation, with histological confirmation of histoplasmosis in the resected intestinal segment.

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.

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.

Generalizability of the Necrotizing Enterocolitis Surgery Trial to the Target Population of Eligible Infants.

OBJECTIVE: The objective of this study was to evaluate whether infants randomized in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network Necrotizing Enterocolitis Surgery Trial differed from eligible infants and whether differences affected the generalizability of trial results. STUDY DESIGN: Secondary analysis of infants enrolled in Necrotizing Enterocolitis Surgery Trial (born 2010-2017, with follow-up through 2019) at 20 US academic medical centers and an observational data set of eligible infants through 2013. Infants born ≤1000 g and diagnosed with necrotizing enterocolitis or spontaneous intestinal perforation requiring surgical intervention at ≤8 weeks were eligible. The target population included trial-eligible infants (randomized and nonrandomized) born during the first half of the study with available detailed preoperative data. Using model-based weighting methods, we estimated the effect of initial laparotomy vs peritoneal drain had the target population been randomized. RESULTS: The trial included 308 randomized infants. The target population included 382 (156 randomized and 226 eligible, non-randomized) infants. Compared with the target population, fewer randomized infants had necrotizing enterocolitis (31% vs 47%) or died before discharge (27% vs 41%). However, incidence of the primary composite outcome, death or neurodevelopmental impairment, was similar (69% vs 72%). Effect estimates for initial laparotomy vs drain weighted to the target population were largely unchanged from the original trial after accounting for preoperative diagnosis of necrotizing enterocolitis (adjusted relative risk [95% CI]: 0.85 [0.71-1.03] in target population vs 0.81 [0.64-1.04] in trial) or spontaneous intestinal perforation (1.02 [0.79-1.30] vs 1.11 [0.95-1.31]). CONCLUSION: Despite differences between randomized and eligible infants, estimated treatment effects in the trial and target population were similar, supporting the generalizability of trial results. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT01029353.

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

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

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

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.

Perforación gástrica y pancreática, con trombosis de vena porta por ingesta de cuerpo extraño / Perforation of the gastrointestinal tract and pancreas, with porta vein thrombosis secondary to the ingestion of a foreign body / Perfuração gástrica e pancreática, com trombose da veia porta por ingestão de corpo estranho

La ingesta accidental de cuerpos extraños en una entidad frecuente en la urgencia, presentándose en general como dolor abdominal inespecífico. Presentamos caso que ingirió un escarbadientes de madera cuyo manejo inicial fue conservador. Su evolución fue tórpida, requiriendo cirugía de urgencia por perforación del estómago y páncreas.

Accidental ingestion of foreign bodies is rather a frequent entity in the ER, presenting in general as non-specific abdominal pain. The study presents the case of a patient who ingested a wooden toothpick, the handling of which was conservative. Evolution was torpid, requiring emergency surgery given the perforation of the stomach and pancreas.

A ingestão acidental de corpos estranhos é uma entidade frequente no pronto-socorro, apresentando-se geralmente como dor abdominal inespecífica. Apresentamos um caso de ingestão de palito de madeira cujo manejo inicial foi conservador. Sua evolução foi complicada sendo necessário realizar uma cirurgia de emergência devido à perfuração do estômago e do pâncreas.

Is it possible to adopt the same oncological approach in urgent surgery for colon cancer?

BACKGROUND: Locoregional complications may occur in up to 30% of patients with colon cancer. As they are frequent events in the natural history of this disease, there should be a concern in offering an oncologically adequate surgical treatment to these patients. AIM: To compare the oncological radicality of surgery for colon cancer between urgent and elective cases. METHODS: One-hundred and eighty-nine consecutive patients with non-metastatic colon adenocarcinoma were studied over two years in a single institution, who underwent surgical resection as the first therapeutic approach, with 123 elective and 66 urgent cases. The assessment of oncological radicality was performed by analyzing the extension of the longitudinal margins of resection, the number of resected lymph nodes, and the percentage of surgeries with 12 or more resected lymph nodes. Other clinicopathological variables were compared between the two groups in terms of sex, age, tumor location, type of urgency, surgical access, staging, compromised lymph nodes rate, differentiation grade, angiolymphatic and perineural invasion, and early mortality. RESULTS: There was no difference between the elective and urgency group concerning the longitudinal margin of resection (average of 6.1 in elective vs 7.3 cm in urgency, P = 0.144), number of resected lymph nodes (average of 17.7 in elective vs 16.6 in urgency, P = 0.355) and percentage of surgeries with 12 or more resected lymph nodes (75.6% in elective vs 77.3% in urgency, P = 0.798). It was observed that the percentage of patients aged 80 and over was higher in the urgency group (13.0% in elective vs 25.8% in urgency, P = 0.028), and the early mortality was 4.9% in elective vs 15.2% in urgency (P = 0.016, OR: 3.48, 95%CI: 1.21-10.06). Tumor location (P = 0.004), surgery performed (P = 0.016) and surgical access (P < 0.001) were also different between the two groups. There was no difference in other clinicopathological variables studied. CONCLUSION: Oncological radicality of colon cancer surgery may be achieved in both emergency and elective procedures.

Evisceración intestinal transvaginal incarcerada con perforación intestinal después de una colporrafia con malla. Reporte de un caso / Incarcerated transvaginal bowel evisceration with intestinal perforation after a mesh colporraphy. A case report

Introducción. La evisceración intestinal transvaginal es consecuencia, en la gran mayoría de casos, de dehiscencia del muñón vaginal posterior a histerectomía en pacientes postmenopáusicas. A través de la dehiscencia vaginal se produce la salida del contenido abdominopélvico, que puede presentarse como una evisceración simple, incarceración, obstrucción, estrangulamiento y perforación de un asa intestinal. Caso clínico. Mujer de 78 años, con antecedente inmediato de colpocleisis y colporrafia con malla de polipropileno por prolapso vaginal, que presentó dehiscencia del muñón vaginal debido a rechazo de la malla, que condicionó la solución de continuidad de la pared vaginal, con prolapso, incarceración, obstrucción y perforación de íleon. Con el diagnóstico de evisceración intestinal transvaginal incarcerada con perforación intestinal se llevó a tratamiento quirúrgico, con abordaje inicial por vía vaginal para liberar el asa intestinal, luego por laparotomía se realizó resección y anastomosis de íleon, sacrocolpopexia con malla y plastia de Douglas. Presentó buena evolución postoperatoria.Conclusión. La evisceración intestinal transvaginal con perforación intestinal es una entidad de muy rara presentación. El órgano más frecuentemente comprometido es el intestino delgado, especialmente el íleon. Puede complicarse con incarceración, obstrucción intestinal, isquemia y perforación. El manejo quirúrgico involucra resección intestinal, cuando hay signos de necrosis, con reparación y fijación del muñón vaginal.

Introduction. Transvaginal intestinal evisceration is a consequence, in the vast majority of cases, of dehiscence of the vaginal stump after hysterectomy in postmenopausal patients. Through vaginal dehiscence, the exit of the abdominopelvic content occurs, which can present as a simple evisceration, incarceration, obstruction, strangulation and perforation of an intestinal loop. Clinical case. A 78-year-old woman with an immediate history of colpocleisis and polypropylene mesh colporrhaphy due to vaginal prolapse, presents dehiscence of the vaginal stump caused by rejection of the mesh that conditioned the solution of continuity of the vaginal wall, prolapse, incarceration, obstruction and perforation of the ileum. Surgical treatment was performed with the diagnosis of incarcerated transvaginal intestinal evisceration with intestinal perforation. The initial approach was to free the intestinal loop vaginally, followed by laparotomy, ileal resection and anastomosis, mesh sacrocolpopexy, and Douglas plasty were performed. He presented good postoperative evolution.Conclussion. Transvaginal intestinal evisceration with intestinal perforation is a very rare entity. The most common organ involved is the small intestine, especially the ileum. It can be complicated by incarceration, intestinal obstruction, ischemia, and perforation. Surgical management involves intestinal resection, when there are signs of necrosis, with repair and fixation of the vaginal stump.

Jejunal perforation secondary to kick during kick-boxing practice: laparoscopic management / Perforación yeyunal secundaria a patada durante práctica de kick-boxing: Manejo laparoscópico

Abstract Small bowel injury in a sports setting is a rare occurrence with a paucity of reported cases. A 30-year old male patient consulted for generalized abdominal pain subsequent to secondary blunt abdominal trauma during kick-boxing practice. A computed tomography scan of the abdomen and pelvis revealed a moderate amount of free fluid in both the parietocolic space and the rectovesical pouch, with perihepatic pneumoperitoneum. Emergency laparoscopy was indicated and a closure of small bowel defect was performed. Diagnosis of small bowel injuries is difficult, resulting in delayed treatment and increased mortality and morbidity.

Resumen La lesión intestinal en un entorno deportivo es infrecuente con pocos casos comunicados. Un varón de 30 años consultó por dolor abdominal generalizado posterior a un traumatismo abdominal cerrado secundario a la práctica de kick-boxing. Una tomografía computarizada de abdomen y pelvis reveló líquido libre tanto en el espacio parietocólico como en la bolsa rectovesical, con neumoperitoneo perihepático. Se indicó laparoscopia exploradora con cirugía de rafia intestinal. El diagnóstico de las lesiones del intestino delgado es difícil, lo que provoca un retraso en el tratamiento y un aumento de la mortalidad y la morbilidad.

Perforación colónica y sepsis fulminante asociada a Clostridium septicum como presentación de un cáncer de colon / Colonic perforation and sepsis associated with Clostridium septicum as clinical presentation of colon cancer

Resumen La asociación entre algunas infecciones bacterianas y cáncer de colon está bien documentada. La más descrita es la infección por Streptococcus bovis. Otra bacteria relacionada a neoplasias intestinales es Clostridium septicum. Presentamos el caso clínico de un varón de 62 años que consultó por dolor abdominal, diarrea y fiebre. Se realizó una tomografía computada de abdomen y pelvis que evidenció un engrosamiento de las paredes del ciego con una aparente solución de continuidad en su borde libre. En una laparotomía exploradora se confirmó la presencia de peritonitis y perforación cecal, siendo sometido a una hemicolectomía derecha e ileostomía terminal. El estudio histopatológico reveló la presencia de un adenocarcinoma de tipo células en anillo de sello asociado a isquemia. Los hemocultivos fueron positivos a C. septicum. El paciente falleció por una sepsis fulminante.

Abstract The association between some bacterial infections and colon cancer is well documented. The most described is Streptococcus bovis infection. Another bacteria related to intestinal neoplasms is Clostridium septicum. We present the case of a 62-year-old man who consulted for abdominal pain associated with diarrhea and fever. A computed tomography scan of the abdomen and pelvis was performed, which revealed thickening of the cecum walls with an apparent break in continuity at its free edge. An exploratory laparotomy was performed which confirmed the presence of peritonitis and cecal perforation. A right hemicolectomy and terminal ileostomy were performed. The histopathological study revealed the presence of signet ring cell type adenocarcinoma associated with ischemia. The blood cultures results demonstrated the presence of C. septicum. The patient died due to fulminant sepsis.

Resultados de la cirugía de urgencia en pacientes con cáncer de colon perforado / Results of emergency surgery in patients with perforated colon cancer

RESUMEN: Gran parte de los pacientes con cáncer de colon (CC), son diagnosticados y tratados de forma electiva. Sin embargo, aproximadamente un 20 % de ellos debutará como una emergencia (obstrucción o perforación). El objetivo de este estudio fue determinar morbilidad postoperatoria (MPO) y supervivencia global (SVG) en pacientes resecados por CC perforado (CCP). Serie de casos retrospectiva de pacientes con CCP, sometidos a colectomía y linfadenectomía, de forma consecutiva, en Clínica RedSalud Mayor y Hospital de Temuco, Chile, entre 2010 y 2019. Las variables resultados fueron SVG y MPO. Otras variables de interés fueron: tiempo quirúrgico, resecabilidad, número de linfonodos resecados, estancia hospitalaria, mortalidad operatoria, recurrencia y supervivencia libre de enfermedad (SLE). Los pacientes fueron seguidos de forma clínica. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión; y análisis de SV con curvas de Kaplan Meier. Se intervinieron 15 pacientes (60 % mujeres), con una mediana de edad de 62 años. La localización más frecuente fue sigmoides (6 casos; 40,0 %). La resecabilidad de la serie fue 100 %. La medianas del tiempo quirúrgico, número de linfonodos resecados y estancia hospitalaria; fueron 80 min, 20 y 5 días respectivamente. La MPO fue 26,7 % (4 casos). Con una mediana de seguimiento de 36 meses, se verificó una recurrencia de 40,0 %. Por otra parte, la SVG y SLE a 5 años fue 46,7 % y 33,3 % respectivamente. Los resultados obtenidos, en términos de MPO y SVG, fueron similares a series internacionales.

SUMMARY: Most patients with colon cancer (CC) are diagnosed and treated electively. However, a fifth of them will debut as an emergency (obstruction or perforation). The aim of this study was to determine postoperative morbidity (POM) and overall survival (OS) in patients resected by perforated CC (PCC). Retrospective case series of patients with PCC undergoing colectomy and lymphadenectomy, consecutively, at RedSalud Mayor Clinic and Temuco hospital, Chile, between 2010 and 2019. The outcome variable were POM and OS. Other variables of interest were surgical time, resectability, number of resected lymph nodes, hospital stay, mortality, recurrence, and disease-free survival (DFS). Patients were followed clinically. Descriptive statistics was used (measures of central tendency and dispersion), and OS analysis was applying Kaplan Meier curves.15 patients (60 % women) were intervened, with a median age of 62 years. The most frequent location was the sigmoid colon (6 cases, 40.0 %). Resectability of the series was 100 %. Median surgical time, number of lymph nodes resected, and hospital stay; they were 80 min, 20 and 5 days respectively. POM was 26.7 % (4 cases). With a median follow-up of 36 months, recurrence was 40.0 %. On the other hand, OS and DFS at 5 years were 46.7 % and 33.3 %, respectively. The observed results, in terms of POM and OS, were like international series.

Jejunal perforation secondary to kick during kick-boxing practice: laparoscopic management.

Small bowel injury in a sports setting is a rare occurrence with a paucity of reported cases. A 30-year old male patient consulted for generalized abdominal pain subsequent to secondary blunt abdominal trauma during kick-boxing practice. A computed tomography scan of the abdomen and pelvis revealed a moderate amount of free fluid in both the parietocolic space and the rectovesical pouch, with perihepatic pneumoperitoneum. Emergency laparoscopy was indicated and a closure of small bowel defect was performed. Diagnosis of small bowel injuries is difficult, resulting in delayed treatment and increased mortality and morbidity.

La lesión intestinal en un entorno deportivo es infrecuente con pocos casos comunicados. Un varón de 30 años consultó por dolor abdominal generalizado posterior a un traumatismo abdominal cerrado secundario a la práctica de kick-boxing. Una tomografía computarizada de abdomen y pelvis reveló líquido libre tanto en el espacio parietocólico como en la bolsa rectovesical, con neumoperitoneo perihepático. Se indicó laparoscopia exploradora con cirugía de rafia intestinal. El diagnóstico de las lesiones del intestino delgado es difícil, lo que provoca un retraso en el tratamiento y un aumento de la mortalidad y la morbilidad.

Intestinal Perforation and Perianal Ulcer Due to Parasitic Infection / Perforación intestinal y úlcera perianal por infección parasitaria

Abstract Balantidium coli is the largest protozoan and the only ciliated parasite that infects humans. It causes balantidiasis, a disease humans acquire by fecal-oral transmission from its usual host: the pig. We report the case of an immunocompetent schoolgirl who presented with peritonitis due to intestinal perforation, with perianal ulceration secondary to polyparasitism caused by Balantidium coli, Enterobius vermicularis, and Trichuris trichiura. It is a rare, potentially preventable complication with extremely high mortality rates. The patient required eight surgical interventions.

Resumen Balantidium coli es el protozoario más grande y el único parásito ciliado que infecta a los seres humanos. Es el causante de la balantidiasis, enfermedad adquirida por los humanos por transmisión fecal-oral desde su hospedero habitual: el cerdo. Reportamos el caso de una escolar inmunocompetente, que presentó peritonitis por perforación intestinal, con ulceración perianal secundaria a poliparasitismo por Balantidium coli, Enterobius vermicularis y Trichuris trichiura. Esta es una complicación poco frecuente, potencialmente prevenible y con tasas de mortalidad extremadamente altas. La paciente requirió 8 intervenciones quirúrgicas.

Spontaneous Anal Extrusion of Ventriculoperitoneal Shunt Catheter: Case Report / Extrusão anal espontânea de catéter de derivação ventriculoperitoneal: Relato de caso

Background Ventriculoperitoneal shunt (VPS) has become the standard treatment for congenital hydrocephalus. In the neurosurgical practice, it is a common procedure which usually results in low rates of complication. However, some serious complications can occur, including infections, intestinal perforation, and even death. Case Description A 19-year-old, female, asymptomatic patient, with a history of appendectomy and revision of the VPS 6 years before, presented spontaneous transanal extrusion of the catheter. Abdominal radiographs and tomography scans showed perforation of the descending colon without peritonitis, with expulsion of the distal tip of the catheter through the anus. The patient underwent removal of the proximal part of the VPS and installation of an external ventricular drain (EVD). On the second postoperative day, there was spontaneous elimination of the distal portion of the catheter, dispensing any additional surgical procedures. With antimicrobial prophylaxis and the contralateral VPS performed, the patient evolved without further complications until discharge. Diverging from cases reported in the literature, the patient in question did not present any abdominal manifestations. Conclusion Intestinal perforation by VPS may be asymptomatic until anal extrusion occurs. However, the early approach should avoid infections, which are associated with increased mortality. Removing only the proximal catheter, together with antimicrobial prophylaxis, can be an effective, safe and less invasive alternative to manage this complication of VPS.

[Perforated metastatic primary fibromyxoid sarcoma of the transverse colon]. / Sarcoma fibromixoide primario de colon transverso metastásico perforado.

Background: Low grade fibromyxoid sarcoma (LGFMS) is considered a rare soft tissue tumor and has a tendency to arise from deep soft tissue of the trunk and lower extremities, the intraabdominal area is considered a rare location. Objective: To describe the first case of a LGFMS arising from the transverse colon with liver metastasis. Clinical case: We describe a 57-years-old male patient with abdominal pain of sudden onset; at surgery he was found to have an abscessed tumor in the transverse colon that infiltrated to mesentery root. An extended left hemicolectomy was performed with ascending colon colostomy. Later on, a postoperative scan he was found to have metastatic liver disease. Conclusions: This case is unique in terms of the location and presentation. It's a reminder of differential diagnosis of acute abdominal pain. To our knowledge is the first case of a LGFMS of the colon with synchronous liver metastasis.

Introducción: el sarcoma fibromixoide de bajo grado (LGFMS) se considera un tumor de tejidos blandos raro, que tiene tendencia a surgir del tronco y de las extremidades inferiores, su localización en el área intraabdominal se considera poco común. Objetivo: describir un caso de LGFMS primario de colon transverso perforado con metástasis hepática. Caso clínico: describimos el caso de un paciente masculino de 57 años con dolor abdominal de inicio súbito; en la cirugía se encontró un tumor con absceso y perforación en el colon transverso que infiltraba hasta la raíz del mesenterio. Se realizó hemicolectomía izquierda extendida con colostomía de colon ascendente. Más tarde, en una exploración posoperatoria, se encontró que tenía enfermedad hepática metastásica. Conclusiones: este caso es único en términos de ubicación y presentación. Es un recordatorio del diagnóstico diferencial del dolor abdominal agudo. Hasta donde sabemos, es el primer caso de LGFMS del colon con metástasis hepática sincrónica.

Surgical management of duodenal perforation after endoscopic retrograde cholangiopancreatography: case series.

BACKGROUND: Complications after endoscopic retrograde cholangiopancreatography (ERCP) are rare, approximately 0.09% to 1.8% are duodenal perforation. This type of injury requires early diagnosis and proper management since the outcomes can be catastrophic, leading to death in 20% of cases. OBJECTIVE: To show our experience in the management of these injuries in order to establish if there is benefit from minimally invasive management versus conventional management. METHOD: Observational, retrospective and descriptive study comparing patients who required surgical management after post-ERCP duodenal perforation in three centers in Bogotá, Colombia, between January 2013 and December 2018. RESULTS: 13 patients were taken to surgical management after duodenal perforation post ERCP, 7 laparoscopically (53.8%), with an average hospital stay of 10.7 days and mortality of 0% and 6 by open route (46.1%), with an average hospital stay of 33 days and mortality of 50%, with a minimum follow-up of 6 months. CONCLUSIONS: Post ERCP duodenal perforation, despite its low incidence, should be suspected due to its high mortality. Laparoscopic surgery is a good tool to address duodenal perforations after ERCP, because it presents a lower rate of complications and mortality.

ANTECEDENTES: Las complicaciones tras la colangiopancreatografía retrógrada endoscópica (CPRE) que necesitan manejo quirúrgico son limitadas y aproximadamente el 0.09-1.8% corresponden a perforación duodenal. Este tipo de lesiones requieren un diagnóstico temprano y un manejo adecuado, ya que los desenlaces pueden ser catastróficos, con una mortalidad reportada de hasta el 20%. OBJETIVO: Presentar nuestra experiencia en el manejo quirúrgico de estas lesiones. MÉTODO: Estudio observacional, retrospectivo y descriptivo, de pacientes que requirieron manejo quirúrgico por perforación duodenal tras CPRE en tres centros de Bogotá, Colombia, entre enero de 2013 y diciembre de 2018. RESULTADOS: Fueron llevados a manejo quirúrgico 13 pacientes, 7 (53.8%) por vía laparoscópica, con una estancia hospitalaria promedio de 10.7 días y una mortalidad del 0%, y 6 (46.1%) por vía abierta, con una estancia hospitalaria promedio de 33 días y una mortalidad del 50%, con seguimiento mínimo a 6 meses. CONCLUSIONES: La perforación duodenal tras una CPRE, pese a su baja incidencia, se debe sospechar por su alta morbimortalidad. La decisión del abordaje quirúrgico está condicionada por el estado clínico del paciente, y por ende está ligada al pronóstico de este.
