abstract OBJECTIVE: To examine the influence of age and gender on the development of proximal gastric pouch distension (PPD) after laparoscopic adjustable gastric banding (LAGB) surgery. BACKGROUND: PPD is the most common reason for revision with adjustable gastric banding surgery. Maintaining the anatomical integrity of bariatric surgery is a key to long-term success. It is therefore important to understand risk factors for complications. METHODS: We extracted details of 3000 consecutive individuals who underwent primary LAGB procedures at a single center between February 2005 and May 2011. Contemporaneous details of all complications were recorded in a database. The characteristics of those that subsequently required revision surgery for PPD were assessed and compared with those that did not. RESULTS: There were 132 cases for PPD requiring surgical intervention before September 2011. Incident PPD occurred in 5.1% and 1.3% of women and men, respectively. The mean age of those with PPD was 39.9 ± 9.25 compared with 43.9 ± 11.0 for those without it. The age and gender effects were independent, and the age effect was restricted to women. The adjusted odds ratios were 0.971 (95% CI [confidence interval], 0.954-0.986, P < 0.001) for age and 0.26 (95% CI, 0.12-0.56, P = 0.001) for male gender and younger women were more likely to have asymmetrical distension. CONCLUSIONS: Younger women are at higher risk of PPD after LAGB surgery than men and women older than 50 years. Sex hormones may play a role in predisposing to gastric stretch after surgery. These findings may apply more broadly to the gastric "restrictive" component of other bariatric procedures.
