This article reviews the use of laparoscopic adjustable gastric banding in the United States today. It comments on the history of the procedure as well as technical aspects of the operation. Short-term and long-term outcomes of the procedure are examined, and the advantages and disadvantages of this procedure in comparison with the laparoscopic gastric bypass are discussed.

ABSTRACT: Background. Laparoscopic adjustable gastric banding (LAGB) is an effective method of reducing excess weight in obese patients. We report a patient who developed a bowel obstruction caused by the connecting tube between the gastric band and the injection port. Case Presentation. The patient was a 42-year-old Caucasian female who had undergone LAGB 19 months earlier. She presented with dehydration, low-grade fever, tachycardia, and mild abdominal tenderness. Laparotomy revealed that the connecting tube was looped around the mesentery, and a loop of small bowel was incarcerated between the tube and the mesentery. The incarcerated small bowel loop was perforated in two places. Conclusion. Surgeons should be aware of the possibility of obstruction caused by the connecting tube in patients who have undergone LAGB.

ABSTRACT: 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/m²) 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.
