Disaster with a new type of band for gastric banding

Laparoscopic gastric banding has become an established therapy for morbid obesity. Typical complications are band dislocation, pouch dilatation and stomach slippage. A new type of adjustable silicone band with eyes for suture fixation was proposed to avoid these complications. The experience with this new kind of band is reported.

Between April 1998 and August 1998, 15 morbidly obese patients were treated by laparoscopic adjustable gastric banding using a new band type (manufactured by MEDING, Heinsberg, Germany). The band was fixed by single sutures using the eyes at each side of the buckle. There were 13 women and 2 men, with mean age 34 (range 21-54) years and mean body-weight 138.6 (range 113-213) kg.

Intraoperative complications did not occur. Postoperatively 8 patients (53%) had increasing capacity for food intake and 2 (13%) had uncharacteristic abdominal pain. Radiographs revealed band rupture in 13 of 15 patients 3-11 months postoperatively. These patients were operated laparoscopically using a new technique for band change. Now, a Lap-band (BioEnterics, Carpinteria, CA, USA) was inserted and fixed to the ventral stomach with three sutures similar to a ventral fundoplication. Radiographic and clinical follow-up have been uneventful in all patients until now.

This series demonstrated: 1) the importance of clinical follow-up; 2) a material defect of a new band type; and 3) development of a new laparoscopic technique for band change.
