Abstract

Background:

The purpose of this study was to assess factors of clinical importance in morbidly obese patients having a laparoscopically adjustable gastric band (LAP-BAND®) implanted in order to achieve weight loss.

Methods:

Preoperative evaluation of hiatus hernia and esophageal (dys)motility were compared with the need for reoperation. Results are presented for the first 50 consecutive patients entered.

Results:

Nine of the first 50 patients required reoperation (18%). Five (10%) were for LAP-BAND slippage on the stomach. Of these five, reoperation was required in four of 12 (33%) with hiatus hernia (P= 0.0093); three of nine (33%) with a motility disorder (P= 0.025); and three of six (50%) with both hiatus hernia and a motility disorder (P= 0.0076).

Conclusions:

We identify two factors, hiatus hernia and esophageal dysmotility, which are associated, both independently as well as in combination, with reoperation for LAP-BAND® slippage. Both patients and their physicians should consider these data when considering the LAP-BAND® as possible therapy for morbid obesity.
