Internal hernia of the small bowel after right-lobe live donor liver transplantation

Abstract

Internal hernia of small bowel is an uncommon but potentially fatal complication of liver transplantation. We report on four patients in whom internal hernia of small bowel occurred after right-lobe live donor liver transplantation (LDLT). Three patients had small bowel herniation with volvulus around the Roux-en-Y loop whereas the other patient had herniation through the mesenteric window of transverse mesocolon after hepaticojejunostomy for biliary reconstruction. Based on clinical and radiologic findings, early diagnosis was made in all cases. All patients survived following surgical reduction of the hernia and closure of the mesenteric defect without bowel resection. Transplant surgeons should be aware of this serious complication so that early diagnosis and appropriate operative intervention can be made. The complication can be avoided with duct-to-duct biliary reconstruction or meticulous closure of all mesenteric defects with non-absorbable suture materials after hepaticojejunostomy in patients undergoing right-lobe LDLT.
