Hallazgo incidental de hernia de Amyand en un lactante de 10 meses de edad con antecedente de prematuridad extrema: Presentación de caso y propuesta de manejo / Incidental finding of Amyand's hernia in a 10-month-old infant with a history of extreme prematurity: Case report and proposed management

Introducción. La hernia de Amyand es una condición en la que el apéndice cecal está contenido dentro del saco herniario inguinal. Su diagnóstico y su manejo continúan siendo un reto al tratarse de una patología poco frecuente. Caso clínico. Lactante varón de 10 meses con antecedente de prematuridad extrema, quien presentó hernia de Amyand derecha con apéndice normal. Se retornó el apéndice a la cavidad y se procedió a la reparación de la hernia. Resultado. Después de un año de seguimiento, el paciente no presentó complicaciones. Conclusiones. Se ha reportado que el riesgo de incarceración en niños nacidos a término es del 12 % y en prematuros del 39 %, por tanto, la reparación quirúrgica de una hernia inguinal siempre es necesaria. No existe un tratamiento estándar para la hernia de Amyand en niños, por tanto, la clasificación CiX podría considerarse para el manejo. Se presenta una propuesta de tratamiento en la población pediátrica, donde se incluyeron 3 tipos, considerando el estadio evolutivo del apéndice cecal y que casi la totalidad de hernias inguinales en niños son debidas a persistencia del proceso vaginal, por tanto, el tratamiento quirúrgico solo incluye herniotomía. Al no utilizar material protésico, se facilita el manejo y se reduce el riesgo de infección.

Introduction. Amyand's hernia is a condition in which the cecal appendix is contained within the inguinal hernia sac, its diagnosis and management continue to be a challenge as it is a rare pathology. Case report. A 10-month-old male infant with a history of extreme prematurity presented a right Amyand's hernia and a normal appendix. The appendix was returned to the cavity and the hernia was repaired. Result. After one year of follow-up, the patient had no complications. Conclusions. Has been reported that the risk of incarceration in full-term children is 12% and in premature babies it is 39%, therefore, surgical repair of an inguinal hernia is always necessary. There is no standard treatment for Amyand hernia in children, therefore the CiX classification could be considered for management. A treatment proposal is presented in the pediatric population, where three types were included, considering the evolutionary stage of the cecal appendix and that almost all inguinal hernias in children are due to persistence of the vaginal process; therefore, surgical treatment only includes herniotomy. By not using prosthetic material, handling is facilitated and the risk of infection is reduced.

Conclusión. Las complicaciones de la herida quirúrgica, el dolor crónico y la recidiva en los pacientes mayores de 80 años a quienes se les realiza herniorrafia inguinal son comparables con las de la población general.

Introduction. Octogenarian and nonagenarian patients constitute a progressively growing age group. Inguinal hernia is a pathology that increases with age. This study aims to understand the surgical outcomes of inguinal herniorrhaphy in patients over 80 years of age. Methods. A systematic review of PubMed, Embase, and Google Scholar was conducted following PRISMA guidelines. Studies reporting the incidence of complications and mortality after inguinal herniorrhaphy in octogenarian and nonagenarian patients were included. The proportion of patients with complications after inguinal herniorrhaphy was calculated based on the data presented, with its respective 95% confidence interval. Results. Fourteen studies reported a total of 19,290 patients, among whom a cumulative incidence of surgical site infection of 0.5 (95% CI 0.460 ­ 0.678), seroma of 8.7% (95% CI 6.212 ­ 11.842), hematoma of 2.6% (95% CI 2.397 ­ 2.893), chronic pain 2.1% (95% CI 0.778 ­ 4.090), recurrence 1.2% (95% CI 0.425 ­ 2.284), and morbidity 14.7% (95% CI 9.525 ­ 20.833) were found. Conclusion. Surgical wound complications, chronic pain, and recurrence in patients over 80 years of age undergoing inguinal herniorrhaphy are comparable to those in the general population.

Tratamiento de la diástasis de rectos asociada a hernias de línea media vía TESuR (Trans-umbilical Endoscopic Sublay Repair) / Management of diastasis recti associated with midline hernias using TESuR (Trans-umbilical Endoscopic Sublay Repair)

RESUMEN Antecedentes: Las hernias de línea media asociadas a diástasis de los músculos rectos anteriores (DRA) son frecuentes y se ha propuesto el tratamiento de ambas patologías simultáneamente para reducir la recurrencia. Las técnicas mínimamente invasivas permiten el tratamiento adecuado con reducción de complicaciones asociadas a la herida quirúrgica; sin embargo, aún no hay consenso acerca de cuál es la mejor técnica. Objetivo: Evaluar los resultados posoperatorios a corto y mediano plazo de una serie de pacientes con defectos de línea media y DRA tratados con la técnica Trans-umbilical Endoscopic Sublay Repair (TESuR). Material y método: Se realizó un estudio observacional descriptivo retrospectivo de pacientes a quienes se les aplicó técnica TESuR entre diciembre de 2020 y marzo de 2023, con un seguimiento posoperatorio mínimo de 6 meses. Se analizaron variables demográficas y perioperatorias. Resultados: En el período de estudio se realizaron 24 reparaciones. Todos los pacientes fueron varones. La edad promedio fue de 57 años (rango 41-81) y el índice de masa corporal (IMC) de 28,9 (21,7- 36,1) kg/m². El área del defecto fue de 8,8 (4-25) cm2, con una DRA de 5,1 (3-9) cm. La tasa de complicaciones a 30 días posoperatorios alcanzó el 17% (4/24); todas fueron Clavien-Dindo I. Con un promedio de seguimiento de 18,6 meses (rango 6-25) no se detectaron recidivas herniarias, aunque dos pacientes (8%) presentaron recidiva de la DRA. Conclusiones: La técnica TESuR presentó una baja morbilidad sin recidivas, por lo que la consideramos una alternativa segura y eficaz para el tratamiento de la DRA asociada a defectos de la línea media.

ABSTRACT Background: Midline hernias associated with diastasis recti abdominis (DRA) are common. Simultaneous treatment of both conditions has been recommended to reduce recurrence. Minimally invasive techniques allow adequate treatment while reducing surgical site complications. However, there is still no consensus regarding the optimal technique. Objective: The aim of this study was to evaluate the short and mid-term outcomes of Trans-umbilical Endoscopic Sublay Repair (TESuR) in patients with midline defects and DRA. Material and methods: We conducted a retrospective descriptive observational study of patients undergoing TESuR between December 2020 and May 2023, with a minimum postoperative follow-up of 6 months. The demographic and perioperative variables were analyzed. Results: A total of 24 procedures were performed during the study period. All the patients were men. Mean age was 57 years (range 41-81) and body mass index (BMI) was 28.9 (21.7- 36.1) kg/m². Mean size of the defect was 8.8 cm2 (4-25) with a mean diastasis width of 5 cm (3-9). The rate of complications at 30 days was 17% (4/24) and were all are grade 1 of the Clavien-Dindo classification. After a mean follow-up of 18.6 months (range 6-25), there were no hernia recurrences, although 2 patients (8%) had a recurrence of DRA. Conclusions: TESuR showed low morbidity rate and absence of recurrences, constituting a safe and effective option for the management of DRA associated with midline defects.

Hernia lumbar de Grynfeltt-Lesshaft / Grynfeltt-Lesshaft lumbar hernias

RESUMEN Las hernias lumbares son defectos infrecuentes de la pared abdominal con pocos casos publicados en la literatura. En la región lumbar existen dos zonas de debilidad, un triángulo superior de Grynfeltt y otro inferior de Petit. Se presenta el caso de una mujer que consultó por dolor y tumoración lumbar derecha. Ante sospecha de hernia lumbar se realizó una tomografía computarizada que informó una hernia de Grynfeltt con contenido de grasa retroperitoneal. Se realizó una plástica protésica por abordaje abierto. No se observaron complicaciones post posoperatorias. Las hernias lumbares pueden ser congénitas o adquiridas, y estas primarias o secundarias. La tomografía computarizada (TC) es el procedimiento de referencia (gold standard) para su diagnóstico. La plástica protésica es el tratamiento de elección. El abordaje abierto y laparoscópico constituyen opciones válidas, y se deben valorar según las características del defecto, el paciente y la experiencia del equipo quirúrgico para su selección.

ABSTRACT Lumbar hernias are rare abdominal wall defects with few cases published in the literature. Two welldefined areas of weakness are identified in the lumbar region, the superior lumbar (Grynfeltt-Lesshaft) triangle and the inferior lumbar (Petit) triangle. We report the case of a female patient who sought medical care due to low back pain and a tumor in the right lumbar region. A lumbar hernia was suspected, and a computed tomography scan was performed, which revealed a Grynfeltt hernia with retroperitoneal fat content. The defect was repaired with mesh placement through an open approach. There were no postoperative complications. Lumbar hernias can be congenital or acquired (primary or secondary). Computed tomography scan is the gold standard for the diagnosis. Mesh repair is the treatment of choice. The open approach and laparoscopy are valid and safe options, and their implementation should be considered based on the characteristics of the defect, the patient, and the experience of the treating team.

Hernia de Spiegel / Spigelian hernia

RESUMEN La hernia de Spiegel es un defecto de la pared abdominal en la que hay protrusión de la grasa preperitoneal, del peritoneo o de algún otro órgano, a través de la línea semilunar situada en el cruce de las fibras de los músculos oblicuos y transverso en el borde lateral del recto anterior del abdomen. Representa el 1 al 2% de todas hernias de la pared abdominal y, en total, ha habido menos de 1000 casos notificados. Se presenta el caso de una paciente de 80 años que consultó por dolor abdominal intermitente en flanco izquierdo. En el examen físico se identificó aumento de volumen de 6 cm en el flanco izquierdo (cinturón de Spiegel) que protruyó con la maniobra de Valsalva, reductible manualmente. Con diagnóstico clínico de hernia lumbar de Spiegel se le realizó una hernioplastia abierta con malla de polipropileno, sin complicaciones.

ABSTRACT Spigelian hernias are defined as a protrusion of preperitoneal fat, peritoneum or an organ through the semilunar line located in the junction of the fibers of the transverse and oblique abdominal muscles laterally to the rectus abdominis muscle. They account for 1% to 2% of all abdominal wall hernias with less than 1000 reported cases. We report the case of an 80-year-old female patient who sought medical care due to intermittent pain in the left lumbar region. On physical examination, an increase in volume of approximately 6 cm was observed in the left lumbar region (Spigelian belt). With the Valsalva maneuver, the structure protruded and was manually reduced. A diagnosis of Spigelian hernia was made, and the patient underwent open repair using polypropylene mesh, without complications.

A novel approach for anatomical repair of ventral hernia with modified smead jones technique

Background: Ventral hernia repair is the most popular procedures done worldwide. Despite of enough literature, evidence for optimal repair is lacking. We introduced a novel surgical technique for open primary ventral hernia repair, using modified smead jones technique. Methods: This prospective interventional study conducted at the department of general surgery in Midnapore Medical College and Hospital from October 2022 to February 2023 aimed to assess the efficacy of the modified smead jones technique in open primary ventral hernia repair. Results: Thirty cases were enrolled, predominantly featuring umbilical hernias in females aged 51-60 years. All cases presented with swelling, pain, and irreducibility. The Modified smead jones technique, employing Prolene no. 1, was utilized, with post-operative complications primarily comprising superficial wound infections managed by IV antibiotics and post-operative pain addressed with adequate analgesia. Recurrence was not observed during follow-ups at 15 days, 1 month, 6 months, and 12 months. Conclusions: The study concludes that this modified technique offers a straightforward approach with low rates of early and potential reduction in late complications, serving as a viable alternative in both elective and emergency settings for primary ventral hernia repair.

Umbilical hernia in pediatric patients attending outpatient department in tertiary care centre

Background: Umbilical hernias are estimated to affect 15% of children. Age, race, gestational age, and coexisting disorders are some of the variables that affect it. In comparison to the general population, there are greater incidences of connective tissue illnesses in children, premature delivery, low birth weight, syndromic newborns, black children, and children with pathologies that raise intraabdominal pressure. To determine the prevalence and to assess the risk factors of umbilical hernia in pediatric patients attending outpatient department (OPD) in tertiary care centre.Methods: The present observational study was conducted in paediatric OPD, of a tertiary care centre over a period of one year. A total of 100 study subjects were enrolled with suspected umbilical hernia. The data was collected with the help of a structured clinical proforma and analysed with SPSS version 20.0.Results: In our study the most prevalent age group involved being 0-1 years (6%) followed by 8-10 years (3%) and 2-4 years (2%). Umbilical hernia was seen more in males (64%) than females. Low birth weight (81%), premature delivery (54.54%), and undernutrition (90.9%) were the risk factors that were observed to be associated with the development of umbilical hernia.Conclusions: The study concluded that the overall prevalence of umbilical hernia was 11% and the associated risk factors were premature delivery, low birth weight and poor nutrition.

A rare case of obstructed lumbar hernia: case report

Lumbar hernias are quite uncommon as compared to other ventral abdominal wall hernias, accounting for less than 1.5% of all abdominal hernias, with fewer than 300 cases reported over the past 300 years. About 25% of all lumbar hernias have a traumatic etiology. This may be post-surgical or following blunt injuries associated with intra-abdominal injuries. The management of such patients constitutes a surgical challenge. Clinical diagnosis of this entity is difficult due to non-specific symptoms. The diagnosis is particularly elusive in obese individuals or in post-surgical patients. Though rare defects, lumbar hernias are prone to incarceration and strangulation. CECT will provide valuable insight into diagnosis of lumbar hernia especially if obstructed or strangulated. Here we present a case report of a rare presentation of obstructed lumbar hernia diagnosed with CT scan and managed with exploratory laparotomy.

Fisiopatología de la hernia diafragmática congénita en el recién nacido / Pathophysiology of congenital diaphramatic hernia in the newborn

La hernia diafragmática congénita es una discontinuidad del diafragma con herniación de los órganos abdominales a la cavidad torácica, actualmente se postula una hipótesis dual para su origen. Su fisiopatología está determinada por la hipoplasia pulmonar, la hipertensión pulmonar y la disfunción ventricular, entender estos elementos es necesario para un adecuado manejo y la mejoría del pronóstico.

Congenital diaphragmatic hernia is a discontinuity of the diaphragm with herniation of the abdominal organs into the thoracic cavity, currently a dual hypothesis for its origin is postulated. Its pathophysiology is determined by pulmonary hypoplasia, pulmonary hypertension and ventricular dysfunction, understanding these elements is necessary for adequate management and improve prognosis.

Comparative study between open versus laparoscopic inguinal hernioplasty

Background: Inguinal hernia repair is one of the commonly performed procedure and has undergone a paradigm shift from open to laparoscopic approach in the era of minimally invasive surgery but the superiority is still debatable. The aim was to compare open (Lichtenstein) versus laparoscopic transabdominal preperitoneal approach (TAPP) hernia repair techniques. Methods: A total of 60 patients were enrolled in the study and divided into two equal groups (open versus laparoscopic) were compared. Results: It was observed that laparoscopic repair (TAPP) has statistically significant superiority than open inguinal hernioplasty in terms of lesser post-operative pain (VAS score of 4.8±0.66, 3.67±0.66, 2.53±0.82 versus 6.7±0.92, 5.03±0.72, 3.83±0.65 at 24 hours, 48 hours and 72 hours post operatively, p value <0.001), shorter duration of hospital stay (3.1±0.71 days versus 5.83±0.75 days, p value <0.001) and early resumption to regular activities (10.57±2.28 days versus 12.2±1.52 days, p value 0.002). It also showed that incidence intra operative and post-operative complications was lesser in laparoscopic group but not statistically significant. Whereas duration of surgery was prolonged in laparoscopic group (104±27.49 min versus 61.5±17.08 min, p value <0.001). Conclusions: Laparoscopic inguinal hernioplasty (TAPP) is superior to open inguinal hernioplasty in terms of lesser intra operative and post-operative complications, lesser post-operative pain, shorter duration of hospital stay with early resumption to regular activities having better subjective and objective cosmetic results in short term follow-up. However, duration of surgery was prolonged on comparison with Lichtenstein open inguinal hernioplasty.

Amyand's hernia: an uncommon entity

A 60-year-old male case whose condition began 6 months prior to admission to the emergency department, presenting an increase in volume in the right inguinal region, with intermittent pain, colic type, with an intensity rating of 8-10/10. On physical examination we found increased volume in the right inguinal region when standing, tumor measuring approximately 5x5 cm, hernia defect approximately 4 cm in diameter, non-painful and reducible. Patient was diagnosed clinically as direct right inguinal hernia and ultrasound confirmed the diagnosis with the presence of the appendix in the sac. A pre-operative diagnosis of right inguinal hernia was made and was planned for hernia mesh repair, during surgery under spinal blockage, the hernia sac was found to contain an appendix without signs of inflammation, so we decided to close the defect and repair with a Lichtenstein mesh hernioplasty without doing an appendectomy. In this case we treated a rare clinical entity called Amyand's hernia. This case highlights the importance of considering Amyand's hernia in the differential diagnosis of inguinal pathologies and the role of imaging modalities in pre-operative diagnosis. Various classification systems have been proposed, including those by Losanoff and Bason, later modified by Rikki et al offering insights into surgical management strategies based on the condition of the appendix and concomitant pathologies. Despite efforts to standardize treatment approaches, consensus on the optimal management strategy remains elusive, necessitating further research to refine diagnostic and therapeutic guidelines.

Hernia de la línea arcuata, una patología poco difundida

La hernia de la línea arcuata (HLA), es una entidad claramente reconocida, sin embargo, existen escasas publicaciones al respecto. Corresponde a un defecto en la vaina posterior del músculo recto del abdomen, separándose la línea arcuata del musculo, formando un bolsillo, lo que corresponde a un defecto inter-parietal y no una verdadera hernia. Probablemente este subdiagnosticado y sub reportado. Su relevancia es que puede constituir una parte relevante de las consultas en servicio de urgencia por dolor abdominal sin etiología demostrada1. El diagnóstico debe sospecharse ante la presencia de dolor abdominal de tipo orgánico, sin otra etiología demostrada. Se confirma con imágenes, especialmente la tomografía computada. El tratamiento, apoyándose en lo reportado en la literatura, sugiere que la vía laparoscópica sería de elección. A continuación, analizamos la anatomía de la linea arcuata, la presentación clínica de esta afección, sus hallazgos imagenológicos, quirúrgicos, y las diferentes alternativas de tratamiento que se han propuesto en la literatura.

The arcuate line hernia is a clearly recognized entity, but of which little is mentioned. It corresponds to a defect in the posterior wall of the rectus abdominis, separating the arcuate line of the muscle, forming a pocket, which corresponds to an interparietal defect and not a true hernia. It is probably underdiagnosed and underreported. Its relevance is that it can constitute a significant part of the consultations in the emergency department for abdominal pain without proven etiology. The diagnosis should be suspected in the presence of organic abdominal pain, with no other proven etiology. It is confirmed with images, especially computed tomography. The treatment, based on what has been reported in the literature, suggests that the laparoscopic approach should be the choice. We analyze the anatomy of the arcuate line, its clinical presentation, imaging and surgical findings, and the different treatment alternatives that have been proposed in the literature.

Manejo expectante de amniocele en paciente con espectro de placenta accreta: reporte de caso / Expectant management of amniocele in a patient with placenta accreta: a case report

Introducción: El amniocele es una hernia del saco amniótico a través de un defecto en la pared del útero, el cual puede deberse a ruptura uterina, secundario a daños preexistentes, anomalías uterinas o en un útero sin cicatrices. Caso clínico: Presentamos el caso de una paciente de 37 años, con antecedente de dos partos por cesárea, a quien en la semana 25,5 de embarazo se le diagnostica por ecografía amniocele en la pared anterior de útero contenido por la vejiga, además de signos ecográficos de acretismo placentario. La posterior realización de resonancia magnética confirma el diagnóstico. Se realiza manejo expectante con estancia continua intrahospitalaria estricta. Resolución obstétrica a las 34 semanas por cesárea, con extracción fetal por fondo uterino sin complicaciones, con posterior realización de histerectomía con placenta in situ. Conclusiones: Este reporte de caso ilustra la importancia de la identificación temprana de esta condición por ser una complicación infrecuente, pero de grave pronóstico fetomaterno en ausencia de atención inmediata.

Introduction: Amniocele is a hernia of the amniotic sac through a defect in the uterine wall, which can be caused by uterine rupture secondary to preexisting damage, uterine anomalies, or a scarless uterus. Case report: We present a case of a 37-year-old patient with a history of two previous cesarean deliveries. At 25.5 weeks of gestation, the diagnosis of amniocele in the anterior uterine wall, contained by the bladder, along with ultrasound signs of placenta accreta, was confirmed through ultrasound. Subsequent magnetic resonance imaging further confirmed the diagnosis. Expectant management with strict continuous intrahospital stay was implemented. Obstetric resolution was achieved at 34 weeks through cesarean delivery, with uncomplicated fetal extraction through the uterine fundus. Subsequently, a hysterectomy was performed with the placenta left in situ. Conclusions: This case report illustrates the importance of early identification of this condition due to its infrequent but serious feto-maternal prognosis in the absence of immediate attention.

Toxina botulínica y neumoperitoneo secuencial en el manejo de hernia inguinoescrotal gigante: Reporte de caso / Botulinum toxin and sequential pneumoperitoneum in the management of giant inguinoscrotal hernia: Case report

Introducción. Las hernias gigantes con pérdida de domicilio son aquellas cuyo saco herniario alcanza el punto medio del muslo en bipedestación y su contenido excede el volumen de la cavidad abdominal. Estas hernias son un reto quirúrgico dada la difícil reducción de su contenido y del cierre primario de la fascia. Tienen mayor riesgo de complicaciones asociadas al síndrome compartimental abdominal, así como mayor tasa de recurrencia y morbilidad en los pacientes. Caso clínico. Paciente masculino de 81 años, reconsultante por hernia inguinoescrotal derecha gigante, de dos años de evolución, sintomática, con índice de Tanaka de 24 %. Se decidió aplicar el protocolo de neumoperitoneo secuencial (hasta 11.000 ml en total en cavidad) además de toxina botulínica en pared abdominal (dos sesiones). Resultados. Se logró la corrección exitosa de la hernia inguinoescrotal gigante, sin recaídas de su patología abdomino-inguinal. El paciente manifestó satisfacción con el tratamiento un año después del procedimiento. Conclusiones. El protocolo de neumoperitoneo secuencial es una alternativa en casos de hernias complejas, con alto riesgo de complicaciones, que requieren técnicas reconstructivas adicionales. La aplicación previa de toxina botulínica es un adyuvante considerable para aumentar la probabilidad de resultados favorables. Sin embargo, debe incentivarse la investigación en esta área para evaluar su efectividad.

Introduction. Giant hernias with loss of domain are those whose hernial sac reaches the midpoint of the thigh in standing position and whose content exceeds the volume of the abdominal cavity. These hernias are a surgical challenge given the difficult reduction of their contents and the primary fascial closure, with a higher risk of complications associated with abdominal compartment syndrome, as well as a higher rate of recurrence and morbidity in patients. Clinical case. A 81-year-old male patient with comorbidity, reconsulting due to a symptomatic giant right inguinoscrotal hernia of two years of evolution, with a Tanaka index of 24%, eligible for a sequential pneumoperitoneum protocol (up to a total of 11,000 cc in cavity) plus application of botulinum toxin (two sessions) in the abdominal wall. Results. Successful correction of the patient's giant inguinoscrotal hernia was achieved using this protocol, without recurrence of his abdomino-inguinal pathology and satisfaction with the procedure after one year. Conclusion. The sequential pneumoperitoneum protocol continues to be an important alternative in cases with a high risk of complications that require additional reconstructive techniques, while the previous application of botulinum toxin is a considerable adjuvant to further increase the rate of favorable results. However, research in the area should be encouraged to reaffirm its effectiveness.

A retrospective study on the surgical management and outcome of congenital diaphragmatic hernia in neonates

Background: Congenital diaphragmatic hernia is a developmental disorder in the anatomy of the diaphragm, which can range from the presence of a thin sac to the frank absence of part of the diaphragm. It results in protrusion of abdominal contents in the chest. CDH once considered as a surgical emergency is no longer a valid dictum. But definitive management of CDH is the surgical correction of defect. Study the demographics, presentation, diagnosis, and surgical outcomes of congenital diaphragmatic hernia (CDH) repair without significant associated congenital anomalies at a tertiary care institute. Methods: This was a retrospective study over 3 years from January 2021 to December 2023. Data was collected and noted from the medical records department. Patient抯 clinical data in terms of demography, presentation, radiology, preoperative condition, timing of surgery after admission, intra-operative findings and post-operative course (including postoperative complications, duration of NICU stay, the incidence of sepsis, and need of inotropes), etc. Results: Most patients were male (85%). Among the total cohort, 70% were born outside the tertiary care institute and were referred from peripheral hospitals. Respiratory distress was the predominant complaint (85%). Congenital diaphragmatic hernia (CDH) was incidentally discovered in 5% of neonates. The majority of patients (70%) underwent surgical intervention between the 3rd postnatal day and up to one week. Left-sided herniation was observed in 90% of cases. An identifiable hernial sac was found in 18% of patients, with part or the entirety of the stomach being the most frequently encountered herniated viscera. Conclusions: Congenital diaphragmatic hernia (CDH) presents as a significant congenital anomaly in the pediatric surgery domain. Hidden mortality in case of CDH leads to underreporting of the actual incidence of the condition. The success of surgical intervention depends on a myriad of factors, encompassing patient-specific attributes and surgical methodologies. However, instances devoid of overt congenital anomalies and featuring stable preoperative physiological parameters typically yield satisfactory surgical outcomes, with favorable results.

Reparação da parede abdominal com membranas acelulares de pericárdio bovino - Parte I - Achados clínicos e radiológicos / Abdominal wall repair with acellular bovine pericardial membranes - Part I - Clinical and radiological findings

Introdução: Reduzindo os índices de recidiva de forma impactante, o emprego de biomateriais como "telas de reforço" na reparação de diferentes defeitos da parede abdominal tornou-se rotina quase obrigatória para o sucesso dessas reparações. A partir da década de 1990 houve a introdução de matrizes biológicas acelulares, iniciando-se assim uma nova era na reparação dos defeitos da parede abdominal. O objetivo é avaliar a funcionalidade do pericárdio bovino acelularizado em reparações da parede abdominal. Método: Trinta pacientes foram submetidos a reparação de defeitos da parede abdominal, com biopróteses acelulares de pericárdio bovino, perfazendo um total de 40 implantes anatomicamente individualizados. O seguimento médio foi de 31 meses, sendo os pacientes avaliados clinicamente e radiologicamente. Em três casos foram feitas biópsias das áreas implantadas permitindo análise histológica do material. Resultados: Não se observou recidiva das herniações em nenhum dos casos, tanto clinica como radiologicamente. Também não houve registro de hematomas, infecções ou qualquer fenômeno de natureza reacional local ou sistêmica. Radiologicamente, não foi possível visualizar as matrizes no local de implantação em qualquer dos períodos de pós-operatório analisados. Conclusão: As matrizes mostraram similaridade às demais membranas biológicas descritas na literatura internacional. Representando uma importante atualização e evolução conceitual, as membranas acelulares de pericárdio bovino podem ser incorporadas ao arsenal terapêutico nas reparações de parede abdominal.

Introduction: Reducing recurrence rates significantly, the use of biomaterials as "reinforcement meshes" in the repair of different abdominal wall defects has become an almost mandatory routine for the success of these repairs. From the 1990s onwards, acellular biological matrices were introduced, thus beginning a new era in the repair of abdominal wall defects. The objective is to evaluate the functionality of the acellularized bovine pericardium in abdominal wall repairs. Method: Thirty patients underwent repair of abdominal wall defects using acellular bovine pericardium bioprostheses, making a total of 40 anatomically individualized implants. The average follow-up was 31 months, with patients being evaluated clinically and radiologically. In three cases, biopsies were taken from the implanted areas, allowing histological analysis of the material. Results: No recurrence of herniations was observed in any of the cases, both clinically and radiologically. There were also no records of bruises, infections or any phenomenon of a local or systemic reaction nature. Radiologically, it was not possible to visualize the matrices at the implantation site in any of the postoperative periods analyzed. Conclusion: The matrices showed similarity to other biological membranes described in the international literature. Representing an important update and conceptual evolution, acellular bovine pericardial membranes can be incorporated into the therapeutic arsenal in abdominal wall repairs.

Reparação da parede abdominal com membranas acelulares de pericárdio bovino - Parte II - Análises histológicas e morfométricas / Repair of the abdominal wall with acellular bovine pericardial membranes - Part II - Histological and morphometric analyses

Introdução: Análise histológica é a principal ferramenta de avaliação de biopróteses acelulares, em sua maioria em caráter experimental. O objetivo é analisar histologicamente a matriz acelular de pericárdio bovino em reparações de parede abdominal implantada em humanos. Método: De uma série de 30 reparações com a membrana, 3 pacientes foram submetidas a revisão cirúrgica não relacionada aos implantes, aos 13, 22 e 23 meses de pós-operatório, obtendo-se biópsias das áreas previamente implantadas. Além da avaliação dos aspectos básicos de biocompatibilidade e neoformação tecidual, as lâminas foram digitalizadas e submetidas a análise computadorizada com o software ImageJ para quantificação da cinética de degradação das membranas, associada à análise da dimensão fractal das amostras. Os valores obtidos para porcentagens de membrana residual tiveram suas médias comparadas por análise de variância (ANOVA) e pelo teste T de Student não pareado, também utilizado para os valores da quantificação da dimensão fractal. Resultados: Foi demonstrada a biocompatibilidade do material, com neoformação tecidual, deposição de colágeno e tecido celularizado de aspecto normal, sem reações locais importantes. Fragmentos residuais da membrana foram quantificados em 40%±7% aos 13 meses, em 20%±6% aos 22 meses e em 17%±6% aos 23 meses de pós-operatório, com a análise da dimensão fractal indicando uma progressiva degradação dos implantes, com significância estatística entre 13 meses e as amostras tardias. Conclusão: Os resultados atestaram a funcionalidade do pericárdio bovino acelular sob diferentes níveis de estresse mecânico nas reparações da parede abdominal em humanos.

Introduction: Histological analysis is the main tool for evaluating acellular bioprostheses, mostly on an experimental basis. The objective is to histologically analyze the acellular matrix of bovine pericardium in abdominal wall repairs implanted in humans. Method: From a series of 30 repairs with the membrane, 3 patients underwent surgical revision unrelated to the implants at 13, 22, and 23 months postoperatively, obtaining biopsies of the previously implanted areas. In addition to evaluating the basic aspects of biocompatibility and tissue neoformation, the slides were digitalized and subjected to computerized analysis with the ImageJ software to quantify the kinetics of membrane degradation associated with the analysis of the fractal dimension of the samples. The values obtained for percentages of residual membrane had their means compared by analysis of variance (ANOVA) and the unpaired Student's T test, also used for the fractal dimension quantification values. Results: The biocompatibility of the material was demonstrated, with tissue neoformation, collagen deposition, and cellularized tissue with a normal appearance without important local reactions. Residual fragments of the membrane were quantified at 40%±7% at 13 months, at 20%±6% at 22 months, and at 17%±6% at 23 months postoperatively, with the analysis of the fractal dimension indicating a progressive degradation of implants, with statistical significance between 13 months and late samples. Conclusion: The results confirmed the functionality of the acellular bovine pericardium under different levels of mechanical stress in abdominal wall repairs in humans.
