Laparoscopic repair of large hiatal hernias

Abstract

Background: The repair of large hiatal hernias can be technically challenging. Most series describing laparoscopic repair report only symptomatic outcomes and the true recurrence rate, including asymptomatic recurrence, is not well documented. This study evaluated the long-term outcome of laparoscopic repair of large hiatal hernias.

Methods: All patients who had undergone laparoscopic repair of a large hiatus hernia (more than 50 per cent of the stomach in the hernia) with a minimum 2-year clinical follow-up were identified from a prospectively maintained database. A standardized questionnaire was used to assess symptoms and a barium swallow radiograph was performed to determine anatomy. Multivariate analysis was used to identify factors associated with recurrence.

Results: Of 100 eligible patients, clinical follow-up was available in 96. Follow-up ranged from 2 to 8 (median 4) years. In patients with preoperative reflux symptoms, there were significant improvements in heartburn and dysphagia scores after surgery. Overall, 80 per cent of patients rated their outcome as good or excellent. Sixty patients underwent a postoperative barium meal examination that identified 14 radiological hernia recurrences (eight small, three medium and three large). Four other patients in this group of 60 had previously undergone reoperation for early and late recurrence (two of each), giving an overall recurrence rate of 18 of 60 (30 per cent). One third of patients with recurrence were totally asymptomatic and the presence of postoperative symptoms did not reliably predict the presence of anatomical recurrence. Younger age and increased weight at operation were independent risk factors contributing to recurrence.

Conclusions: Laparoscopic repair of large hiatal hernias yields good clinical outcome. Recurrence after laparoscopic repair seems to be more common than previously thought. Objective anatomical studies are required to determine the true recurrence rate. The majority of recurrences are not large and do not cause significant symptoms.
