Laparoscopic repair of paraduodenal hernia: comparison with conventional open repair

Abstract

Paraduodenal hernia is a congenital internal hernia caused by abnormal retroperitoneal fixation of the intestinal mesentery. The management of paraduodenal hernia consists of reduction of the herniated intestine and repair of the defect. Recently, laparoscopic surgery has been increasingly performed in abdominal procedures. To evaluate the feasibility and efficacy of laparoscopic repair of paraduodenal hernia, we present our experience in 2 cases of laparoscopic repair, compared with 3 other cases treated with conventional open repair; all 5 cases were successfully treated. All patients had symptoms of intestinal obstruction and were diagnosed by preoperative abdominal computed tomography. Two cases were right-sided hernias, and 3 cases were left sided. Among them, 2 patients with left-sided paraduodenal hernia underwent laparoscopic reduction (LR group) of the herniated small bowel, and the other 3 cases underwent open reduction (OR group). In the LR group, the duration of hospital stay, time to first flatus, and time to first intake of a soft diet were shorter than in the OR group. Thus, with an accurate preoperative diagnosis of paraduodenal hernia, laparoscopic surgery may be a feasible and efficient procedure, with good postoperative outcomes.
