Patients and methods
A retrospective review was performed on prospectively collected data on all RYGBP procedures performed at a single institution from July 1997 to August 2005. Institutional review board approval was obtained before initiation of this retrospective study. Both open and laparoscopic procedures were included in the analysis. In all cases, the jejunum was divided 30 cm distal to the ligament of Treitz. The standard length of the Roux limb was 75 cm. Patients with a BMI >50 received a 150-cm Roux
Results
Gastric bypass was performed on 801 patients (open RYGBP in 294 patients, laparoscopic RYGBP in 507 patients). The mean preoperative BMI was 55.1 kg/m2. The mean age at surgery was 44.5 years, and 81% of the patients were women. Baseline patient characteristics and weight loss in the first year are shown in Table 1. The excess weight loss and BMI at 1 year fell within the range considered to be a good result.
Gastrojejunal anastomotic stricture developed in 43 of 801 patients (5.4%) (Table 2).
Discussion
Morbid obesity is reaching epidemic proportions in many westernized countries. Medical therapies have been largely unsuccessful in maintaining significant sustained weight loss. Surgery for morbid obesity is currently the only proven option for long-term weight loss. Consequently, the number of bariatric surgeries and resulting complications are likely to increase. Gastrojejunal anastomotic strictures remain a relatively frequent complication, occurring in up to 16% in some studies.5, 10, 11, 14

2020, Surgical Clinics of North AmericaCitation Excerpt :Endoscopic balloon dilation of benign strictures is generally successful. Gastrojejunal anastomotic strictures after gastric bypass procedures have an 80% success rate after one dilation, and more than 90% success with 2 or more dilations.23 Benign gastric strictures can also follow sleeve gastrectomy procedures and similar outcomes have been demonstrated with greater than 70% success after balloon dilation.24
