Stoma adjustable silicone gastric banding: results in 111 consecutive patients.

From April 1990 through December 1992, 111 patients (80 females, 31 males, mean age 38 years, range 16-60) underwent stoma adjustable silicone gastric banding (SASGB) at the Department of Surgery, University Hospital, Padua, Italy. Patients' characteristics were: mean height 166 +/- 8 cm; mean body weight (BW) 129.1 +/- 21.6 kg; mean body mass index (BMI) 46.4 +/- 6.3 kg/m(2); mean percentage of ideal body weight (%IBW) 206.2 +/- 27. Eighty-eight patients were morbidly obese and 23 superobese. All patients were available for follow-up. Median follow-up was 18.8 months (range 12-44). At I year (I 03 patients), mean postoperative BW, BMI, %IBW and excess weight lost (%EWL) were 101.5 +/- 20 kg, 36.5 +/- 6 kg/m(2), 164 +/- 30 and 40.8 +/- 19 respectively; at 2 years (58 patients) 92.3 +/- 19 kg, 33.1 +/- 6 kg/m(2), 148.8 +/- 28, 52 +/- 23, respectively, and at 3 years (26 patients) 86.9 +/- 14 kg, 31.4 +/- 5 kg/m(2), 141.5 +/- 25 and 63.6 +/- 20 respectively. The overall postoperative mortality rate was zero and the early morbidity rate 9%. Late complications were band slippage (two patients), stoma stenosis with pouch dilatation (seven patients), band erosion (one patient), reservoir leakage (three patients) and reservoir infection (two patients). Surgical revision was performed in ten (9%) patients, two of whom required band removal. Most complications occurred in patients who underwent SASGB during our initial experience. Our findings confirm that SASGB is a safe and effective surgical means of achieving weight reduction.
