Revisional surgery after failed adjustable gastric banding: institutional experience with 90 consecutive cases.

摘要

Revisional surgery may be required in a high percentage of patients (up to 30 %) after laparoscopic adjustable gastric banding (LAGB). We report our institutional experience with revisional surgery.From January 1996 to November 2011, 90 patients underwent revisional surgery after failed LAGB. Both Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) were proposed. In the presence of gastroesophageal reflux disease, esophageal dysmotility, hiatal hernia, or diabetes, RYGB was preferentially proposed.In two cases, revisional surgery was aborted due to local severe adhesions. Eighty-eight patients (74 females; mean age 42.79 ± 10.03 years; mean BMI 44.73 ± 6.19 kg/m(2)) successfully underwent revisional SG (n = 48) or RYGB (n = 40). One-stage surgery was performed in 29 cases. Follow-up rate was 78.2 % (n = 61) and 40.9 % (n = 36) at 12 and 24 months respectively. One major complication after SG (staple-line leakage) was observed. Overall postoperative excess weight loss (%EWL) was 31.24, 40.92, 52.41, and 51.68 % at 3, 6, 12, and 24 months of follow-up respectively. There was a statistically significant higher %EWL at 1 year in patients <50 years old (55.9 vs. 41.5 % in patients >50 years old; p = 0.01), of female gender (55.22 vs. 40.73 % in male; p = 0.04), and in patients in which the AGB was in place for <5 years (57.09 vs. 47.43 % if >5 years p = 0.02).Revisional surgery is safe and effective. Patients <50 years, of female gender, and with the AGB in place for <5 years had better %EWL after revisional surgery.
