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.


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.


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).


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.
