The Effect of Gastric Band Slippage on Patient Body Mass Index and Quality of Life

Quality of life after laparoscopic adjustable gastric banding (LAP-BAND): APEX interim 3-year analysis

BACKGROUND

Obesity is often associated with diminished health-related quality of life (HRQOL), but significant gains in HRQOL have been observed after bariatric surgery. Laparoscopic adjustable gastric banding has been established as a safe, effective treatment to reduce weight in patients with obesity. This report summarizes interim 3-year changes in HRQOL and body weight, as well as safety postimplantation of the LAP-BAND AP (LBAP) system.

METHODS

The LAP-BAND AP EXperience (APEX) trial, an ongoing, prospective, 5-year, open-label study, assessed changes in HRQOL (Obesity and Weight-Loss Quality of Life [OWLQOL] questionnaire) and body weight, and safety after placement of LBAP. This interim analysis represents patients with evaluable OWLQOL data at baseline and at 3 years (n = 183).

RESULTS

The OWLQOL total score and individual scores significantly improved within 6 months post-LBAP and continued to improve during a 3 year period (P < 0.0001, both). Total score improved from 71.0 to 34.0 (mean improvement from baseline, 52%; range, 18%-65%); mean change in individual scores was -2.2 (range, -0.7 to -3.0). Percent weight loss was maintained through 3 years (19.4%; n = 174). Improvement in OWLQOL was associated with percent weight loss at 3 years (r = -0.5407; P < 0.0001). Revisions and explants were performed in 7 (3.8%) and 20 (10.9%) out of 183 patients, respectively.

CONCLUSIONS

Meaningful improvement in quality of life occurred through clinically significant weight loss after LBAP placement, extending throughout the 3 years of this analysis.

Systematic review on reoperative bariatric surgery: American Society for Metabolic and Bariatric Surgery Revision Task Force

BACKGROUND

Reoperative bariatric surgery has become a common practice in many bariatric surgery programs. There is currently little evidence-based guidance regarding specific indications and outcomes for reoperative bariatric surgery. A task force was convened to review the current evidence regarding reoperative bariatric surgery. The aim of the review was to identify procedure-specific indications and outcomes for reoperative procedures.

METHODS

Literature search was conducted to identify studies reporting indications for and outcomes after reoperative bariatric surgery. Specifically, operations to treat complications, failed weight loss, and weight regain were evaluated. Abstract and manuscript reviews were completed by the task force members to identify, grade, and categorize relevant studies.

RESULTS

A total of 819 articles were identified in the initial search. After review for inclusion criteria and data quality, 175 articles were included in the systematic review and analysis. The majority of published studies are single center retrospective reviews. The evidence supporting reoperative surgery for acute and chronic complications is described. The evidence regarding reoperative surgery for failed weight loss and weight regain generally demonstrates improved weight loss and co-morbidity reduction after reintervention. Procedure-specific outcomes are described. Complication rates are generally reported to be higher after reoperative surgery compared to primary surgery.

CONCLUSION

The indications and outcomes for reoperative bariatric surgery are procedure-specific but the current evidence does support additional treatment for persistent obesity, co-morbid disease, and complications.
