Successful management of gastrojejunal strictures after gastric bypass: is timing important?

BACKGROUND: Endoscopic balloon dilation is an effective treatment of gastrojejunal (GJ) strictures after Roux-en-Y gastric bypass (RYGB), although its success might depend on the point at which they occur postoperatively. We hypothesized that "late" strictures (≥90 d after RYGB) might be less amenable to balloon dilations than "early" strictures occurring within 90 days postoperatively. METHODS: A review of a prospectively maintained database at a bariatric center was conducted to identify all patients who underwent upper endoscopy (UE) for investigation of gastrointestinal symptoms after RYGB. Those who were diagnosed with a GJ anastomotic stricture at endoscopy were selected for additional evaluation. The patients were classified into 1 of 3 groups, according to the point at which they presented with stricture symptoms (group 1, 0-90 d after RYGB; group 2, 91-365 d after RYGB; and group 3, >1 yr after RYGB). All strictures were dilated using through-the-scope controlled radial expansion balloons. RESULTS: From July 2006 to July 2009, 929 RYGB procedures were performed in our bariatric unit. Our surgical endoscopy team performs approximately 1500 UE investigations annually. Most investigations were for preoperative assessment of bariatric patients; however, a proportion is indicated for the investigation of postoperative weight regain and complications of foregut surgery, as well as endoluminal surgery. In the present study period, 591 gastric bypass patients underwent UE for investigation of gastrointestinal symptoms postoperatively. In total, 72 patients were diagnosed with a symptomatic GJ anastomotic stricture and underwent balloon dilation. Almost two thirds (63.9%) of the dilations were performed within 90 days after RYGB; 98% of these "early" strictures resolved with dilation. In comparison, of the "late" strictures, only 61% (16 of 26 patients) resolved and 38.5% (n = 10) required revisional surgery for additional management. CONCLUSION: Endoscopic balloon dilation is effective in treating early GJ strictures after RYGB. Late strictures are less amenable to endoscopic dilation and often require revisional surgery. Patients presenting with upper gastrointestinal symptoms after RYGB warrant early investigation with UE to investigate for a GJ stricture, which if present, should be promptly dilated.

Pre-Lap-Band group education in Medicaid population: does it really make a difference?

BACKGROUND: The effect of group education classes before a Lap-Band procedure has not been well defined. We hypothesized that in a Medicaid population, the completion of a standardized 12-week multidisciplinary preoperative program (SMPP) would significantly improve the preoperative and early postoperative weight loss. All procedures were performed at a University-affiliated community hospital from 2006 to 2007. METHODS: A prospectively collected database of 292 patients who underwent Lap-Band placement was retrospectively reviewed. All patients in the study cohort were encouraged to participate in the SMPP, which included medical, psychological, and nutritional interventions. The patients were divided into 2 groups according to their participation in the SMPP program: SMPP compliant and non-SMPP compliant. The postoperative weight loss of these 2 groups was then compared using the general linear models for repeated measures statistical analysis. RESULTS: No significant difference was found in the mean baseline excess body weight between the 2 groups (74 +/- 20 kg in the SMPP-compliant and 76 +/- 20 kg in the non-SMPP-compliant participants). The mean baseline body mass index (47 +/- 7 versus 48 +/- 72 kg/m(2) for the SMPP-compliant and non-SMPP-compliant participants) was also similar in the 2 groups. The postoperative follow-up rate was 94.5% at 1 month, 72.3% at 6 months, and 52.7% at 12 months. The excess weight loss was significantly greater in the SMPP compliant group than in the noncompliant group during the observed 12-month follow-up period (P = .04, by general linear models for repeated measures). CONCLUSION: In a Medicaid population, implementation of an intensive preoperative SMPP resulted in a significant improvement in the short-term weight loss after Lap-Band placement.
