Internal hernia after laparoscopic left colectomy: case series and review of the literature

Objective: Laparoscopic colectomy has gained acceptance as a standard treatment for benign and malignant colorectal disease, such as diverticular disease and cancer, among others. Same as in open surgery, the laparoscopic approach carries a low risk of small bowel obstruction in the postoperative period, but in laparoscopic surgery, internal hernia after laparoscopic left colectomy may be a cause of small bowel obstruction with a significant risk of morbidity and mortality. This rare complication may be prevented with routine closure of the mesenteric defects created during the colectomy. Methods: We present four cases of internal herniation after laparoscopic colectomy. Two cases were after laparoscopic left colectomy and two after laparoscopic low anterior resection. All four cases had full splenic flexure mobilization. Routine closure of the mesenteric defect was not performed in the initial surgery. Results: The four patients were treated by laparoscopic reintervention with closure of the mesenteric defect. In two of them, conversion to open surgery was necessary. One of the patients developed recurrent internal herniation after surgical reintervention with mesenteric closure of the defect. All patients were managed without need for bowel resection, and mortality rate was 0%. Conclusion Internal herniation after laparoscopic colorectal surgery is a highly morbid complication that requires prompt diagnosis and management and should be suspected in the early postoperative period. Additional studies with extended follow-up are required to establish recommendations regarding its prevention and management. (AU)

Hernia transmesentérica. Revisión del tema a raíz de un caso exótico de infarto intestinal en un adulto / Transmesenteric hernia. A literature review following an exotic case of intestinal infarction in an adult / Hérnia transmesentérica. Revisão do tema a raiz de um caso exótico de enfarte intestinal num adulto

Introducción: la hernia transmesentérica (HT) es una causa extremadamente rara de isquemia intestinal en adultos, con pocos casos reportados en la literatura. Presentación del caso: un hombre de 71 años presentó dolor epigástrico severo de seis horas de evolución, sin signos de obstrucción intestinal ni historia de cirugías abdominales previas. Ante el deterioro clínico se hizo una laparotomía que reveló un defecto transmesentérico de 4 cm en el yeyuno y herniación de ciento noventa cm de intestino delgado con signos de gangrena. Se efectuaron reducción del contenido, resección intestinal y anatomosis primaria. La recuperación fue exitosa y fue dado de alta diez días después del ingreso. Discusión: los síntomas clínicos, los estudios radiológicos y los datos de laboratorio suelen ser inespecíficos para el diagnóstico de HT. La tasa de mortalidad puede superar el 50 %. Este artículo resume las características clínicas más importantes a partir de una revisión exhaustiva de la literatura. Conclusión: la obstrucción intestinal por HT es una condición potencialmente letal. Los signos y síntomas clínicos relacionados con HT exigen un estricto seguimiento. Si no hay mejoría o se presenta deterioro clínico, se debe hacer una cirugía temprana con el fin de reducir la mortalidad y la morbilidad por esta causa.

Introduction: Transmesenteric hernia (TH) is an extremely rare cause of bowel ischaemia in adults with few reported cases. Case report: A 71-year-old man experienced six hours of severe epigastric abdominal pain, without signs of intestinal obstruction and with no history of abdominal surgery. In response to clinical deterioration, an emergency laparotomy was performed, revealing a 4 cm transmesenteric defect in the jejunal region. One hundred ninety centimeters of the small bowel were herniated through the defect and became gangrenous. The hernia was reduced, small bowel resected, and primary anastomosis performed. The patient recovered and was discharged ten days later. Discussion: Clinical symptoms, radiological imaging, and laboratory tests can be non-specific in the diagnosis of TH. The mortality rate is higher than 50 %. This paper summarizes the most important clinical traits based on a comprehensive literature review. Conclusion: Intestinal obstruction due to TH is a potentially lethal condition. The important clinical traits related to TH should be closely monitored. If there is no improvement or clinical deterioration occurs, it is mandatory to do early surgery to reduce morbidity and mortality.

Apresentação do caso: um homem de 71 anos apresentou dor epigástrico severo de seis horas de evolução, sem signos de obstrução intestinal nem cirurgias abdominais prévias. Ante a presença de deterioração clínica se fez uma laparotomia que revelou um defeito transmesentérico de 4 cm no jejuno e rupturas de cento noventa cm de intestino delgado com signos de gangrena. Efetuaram-se redução do conteúdo, resseção intestinal e anastomoses primária. A recuperação foi exitosa e foi cadastrado dez dias depois do rendimento. Discussão: os sintomas clínicos, os estudos radiológicos e os dados de laboratório costumam ser inespecíficos para o diagnóstico de HT. A taxa de mortalidade pode superar 50 %. Este artigo resume as características clínicas mais importantes a partir de uma revisão exaustiva da literatura. Conclusão: a obstrução intestinal por HT é uma condição potencialmente letal. Os signos e sintomas clínicos relacionados com HT exigem um estrito seguimento. Se não há melhoria ou se apresenta deterioração clínica, deve-se fazer uma cirurgia temporã com o fim de reduzir a mortalidade e a morbilidade por esta causa.

Result of using a biologic collagen implant (Permacol) for mesenteric defect repair after excision of a huge mesenteric lymphangioma in a child

Mesenteric lymphangiomas, which involve near total mesentery, are extremely rare. A mesenteric lymphangioma should be treated through excision because they can cause invasion of vital structures, bleeding, or infection. After excision of a huge mesenteric lymphangioma, internal herniation may occur through a large mesenteric defect leading to intestinal volvulus, obstruction, and other life-threatening circumstances. We report a case in which a biologic collagen implant (Permacol) was used for mesenteric defect repair after excision of a huge mesenteric lymphangioma. The implant did not cause any symptoms or complications during follow-up for 4 years. When encountering large defects of mesentery, closure with implant can be a feasible choice, and Permacol could be a possible implant for closing the defect.

Diagnosis and Treatment of Congenital Mesenteric Hiatual Hernia / 实用儿科临床杂志

Objective To explore the early diagnosis and treatment of congenital mesenteric hiatual hernia.Methods A retrospective study was carried out in 4 patients with congenital mesenteric hiatual hernia in Tongji hospital from Nov.2005 to Mar.2007,and combining lite-rature,the diagnosis and treatment of mesenteric hiatal hernia was summed up.Results Four patients were diagnosed in operation.One case was thought as adhesive intestinal obstruction before operation;two patients were on emergency operation and 2 patients were on time-elective operation;one patient preoperative CT scan may suggest mesenteric hiatal hernia;one case had partial resection of small intestinal,the others were replaced the intestine and fixed the defect.One patient occurred early septic shock;all of them had get well.Conclusions It′s hard to diagnose the congenital mesenteric hiatual hernia before operation.Abdomen CT examination and multislice spiral CT angiography (MSCTA) help to diagnose.Early diagnosis and timely operation are the therapeutic key of congenital mesenteric hiatual heria.For the patients with recurrent abdominal pain,who was not confirmed with a variety of inspection,laparoscopic exploration can provide diagnosis,and can take the initiative to control the development of disease.

Transmesenteric Hernia: 3 Autopsy Cases / 대한법의학회지

Transmesenteric hernia is a rare cause of small bowel obstruction and is caused by congenital mesenteric defect or postoperative complication. At first because it is a rare type of internal hernia and also clinical simptoms can be nonspecific or intermittent, it is seldom diagnosed before laparotomy or autopsy. We report 3 cases, 1-, 2-, and 4-year-old children and found a small bowel gangrene caused by a congenital defect of mesentery. We describe autopsy findings, clinical simptoms and clinical diagnosis.
