11-cm Lap-Band System placement after history of intragastric migration.

Abstract

Intragastric migration (erosion) of the band after laparoscopic adjustable silicone gastric banding (LAGB) is a serious late complication. It requires removal of the entire system. Subsequent recurrence of obesity can be treated by laparoscopic placement of a larger band: the 11-cm Lap-Band System. In 727 laparoscopic gastric bandings using the 9.75 Lap-Band, 10 cases presented with intragastric migration of the band. The same complication was encountered in an additional 4 patients who had previously been implanted with an Obtech band in another hospital. Laparoscopic removal of the band was performed in all cases. In 9 cases, after a delay of 6 months, a new gastric band was placed using the 11-cm Lap-Band, because of uncontrollable recurrence of obesity. No complication was observed during the laparoscopic removal of the system. The placement of a new band required conversion to laparotomy in 1 patient who had previously received an Obtech band which had been placed using the pars flaccida technique. After a mean follow-up of 21 months, no intragastric migration of the new bands was noted. Laparoscopic placement of an 11-cm Lap-Band in patients with a history of intragastric migration is a safe procedure. It allows effective control of recurrent obesity. The laparoscopic procedure was easier in patients initially operated using the perigastric technique.
