Laparoscopic repair of large hiatal hernia without prosthetic reinforcement: late results and relevance of anterior gastropexy.

Background: Laparoscopic treatment of large hiatal hernias seems to be associated with a high recurrence rate that some authors suggest to bring down by performing prosthetic closure of the hiatus. However, prosthetic repair remains controversial owing to severe and still underestimated complications. The aims of this study were to assess the long-term functional and objective results of laparoscopic treatment without prosthetic patch, and to identify the risk factors of recurrence.

Methods: From November 1992 to March 2009, 89 patients underwent laparoscopic treatment of a large hiatal hernia without prosthetic patch, involving excision of the hernial sac, cruroplasty, fundoplication, and often anterior gastropexy. The postoperative assessment consisted of a barium esophagram on day 2, an office visit at 2 months with a 24-h pH study, an esophageal manometry, and then a long-term prospective yearly follow-up with a barium esophagram at 2 years.

Results: Out of the 89 laparoscopic procedures, four required a conversion (4.4%). Seventy-seven patients underwent a Boerema's anterior gastropexy (86.5%). The morbidity rate was 7.8%, and the mortality rate was nil. Eleven patients (12.3%) were lost to follow-up. We had 91.5% of very good early functional results and 75.3% of good results after a mean follow-up of 57.5 months. Fourteen recurrences of hiatal hernias (15.7%) were identified, four of which (28.6%) occurred early after surgery. Three factors seemed significantly associated with recurrence: the absence of anterior gastropexy (p = 0.0028), the group of younger patients (p = 0.03), and a history of abdominal surgery (p = 0.01).

Conclusion: Large hiatal hernias can be treated by laparoscopy without prosthetic patch with a satisfying long-term result. Performing anterior gastropexy seems to significantly reduce the recurrences.
