Symptomatic and radiological follow-up after para-esophageal hernia repair

Abstract

The treatment of para-esophageal hernia by the laparoscopic approach has been described by a number of authors. The lower morbidity of the laparoscopic approach compared with the open approach holds some attraction, however, reservations regarding the durability of laparoscopic repair exist. There is a paucity of objective follow-up data in the literature with regard to repair durability and symptomatic outcome. A review was undertaken of 94 patients over a 7 year period undergoing attempted laparoscopic repairs of para-esophageal hernia. Preoperative and operative data was collected and patients underwent postoperative interview and barium meal. Laparoscopic repair was successfully completed in 86 patients. Symptomatic reherniation occurred in 12% (10/86) of patients undergoing laparoscopic repair. These patients underwent open reoperative surgery. There were no symptomatic recurrences in patients undergoing initial open repair. Symptomatic outcome was assessed by interview in 78% (73/94) of patients at a median of 27 months (3-93 months) postoperatively. Ninety-seven percent (71/73) of patients were satisfied with their ultimate symptomatic outcome however, this group included seven patients who had required reoperative surgery for symptomatic recurrence and were therefore laparoscopic failures. In order to determine the asymptomatic recurrence rate patients were requested to undergo a barium meal. A further nine small asymptomatic recurrences were diagnosed in 42 patients having had laparoscopic repair. This represents an asymptomatic radiographic recurrence rate of 21%. Laparoscopic repair in this series was associated with a 12% symptomatic recurrence rate. The majority of patients with symptomatic recurrence underwent open reoperation with good results. Strategies for reducing recurrences should be examined in prospective series.
