Abstract:Objective:To investigate the causes of intra-abdominal hernia and improve the level of early diagnosis and therapy of intra-abdominal hernia. Methods:A retrospective analysis of the clinical data of 68 cases of intra-abdominal hernia was made. Results:The postoperative confirmed diagnosis was para-occal hernia in 1 patient;herniation of efferent jejunal loop through the space between the afferent jejunal loop and the mesocolon after Billroth II gastrectomy in 6 patients,one of which had bowel necrosis,all of the 6 patients were cured after reduction of the hernia or enterectomy after and enteroanastomsis;internal henia though ruptured pelvic peritoneum after Miles operation in 4 patients;internal hernia though the space between the descending colon and the lateral abdominal wall after colostomy of descending colon in 6 patients;internal hernia caused by adhesion of omentum to the intestinal wall of sigmoidostomy in 1 patient;internal hernia through hiatuses caused by postoperative or post-peritonitis adhesions to the peritoneum,ovaries,urinary bladder,uterus,intestinal wall or between loops of intestine in 50 patients(73.5%),including 3 cases of bowel necrosis.All of those patients were cured after reduction of the hernias,repair of the hiatuses,release of adhesions or enterectomy and enteroanastomosis. Conclusions:Preoperative diagnosis of internal abdominal hernia is difficult.The possibility of internal abdominal hernia should be cansidered in patients with a history of operation,and who complain of frequent abdominal pain or bowel obstruction.Early diagnosis and prompt operation is necessary to prevent the occurrence of bowel strangulation and bowel necrosis.
