Revisional Adjustable Gastric Band in Roux-en-Y Gastric Bypass—Is It Worth It?

Purpose A subset of patients undergoing Roux-en-Y gastric bypass (RYGB) presents with either insufficient weight loss or weight regain. Data on the revisional restrictive options including laparoscopic adjustable gastric band (LAGB) is scarce. This study analyzes the mid-term efficacy and safety of LAGB as a revisional procedure after RYGB. Methods Data of all patients with revisional LAGB after primary RYGB between January 2011 and May 2019 were retrospectively reviewed. Outcomes included assessment of weight changes, resolution of comorbidities, and early and late complications during the study period. Results Twenty patients were included. The median Body Mass Index (BMI) before revisional LAGB was 34.8 (interquartile range [IQR] 31.9–38.1) kg/m2. After a median follow-up of 33.5 (IQR 19.5–76.5) months, the median BMI was 28.7 (IQR 26.1–32.2) kg/m2. The median additional Excess Weight Loss (EWL) was 37.6% (IQR 23–44.4), leading to a median total EWL of 79.5% (IQR 54.4–94.6). BMI and EWL post-LAGB improved significantly compared to BMI and EWL pre-LAGB (p<0.001 and p<0.001, respectively). Obstructive sleep apnea syndrome resolved 6 months after LAGB in one patient. Three band deflations occurred during the follow-up. Six patients underwent band removal after a median time of 19 (IQR 15.8–26) months. Overall, thirteen patients underwent a reoperation. There was no loss of follow-up until 5 years. After that, two patients were lost to follow-up. Conclusion LAGB may be a salvage option after failed RYGB. However, the high rate of revisions after secondary LAGB needs to be taken into consideration.

Obstrucción intestinal, complicación inusual por banda gástrica ajustable laparoscópica: reporte de caso

Background: The main goal of bariatric surgery is the reduction of Body mass index (BMI). Laparoscopic adjustable gastric band (LAGB) was the most popular method due to its relative advantages over others. Clinical case: A 44-year-old woman with abdominal pain and distension, with a history of LAGB placement had a diagnosis of intestinal occlusion secondary to a twist in the device tube, surgical management was given, the patient presented adequate evolution. Conclusion: The occlusion of the small intestine by the tube of the device is a serious and uncommon complication to be considered as a differential diagnosis in bariatric patients.
