Abstract
OBJECTIVE: To evaluate the safety and efficacy of revisional Roux-en-Y gastric bypass (RYGB) after adjustable gastric banding (AGB) or sleeve gastrectomy (SG) compared with primary RYGB, in regard to early and late morbidity, weight, and resolution of obesity-related comorbidities. METHODS: The group of patients undergoing revisional RYGB was matched in a 1:1 ratio with control patient who underwent a primary RYGB, based on age, gender, American Society of Anesthesiologist (ASA) score, preoperative body mass index (BMI), and diabetes mellitus. Demographics, anthropometrics, preoperative work-up, and perioperative data were retrieved. RESULTS: One hundred fifteen patients (16 males and 99 females) with a mean age of 45.5 ± 1.5 years underwent revisional RYGB following either LAGB in 82 patients (71.3%) or laparoscopic sleeve gastrectomy (LSG) in 33 patients (28.7%). There was no conversion and no mortality in either group. Revisional RYGB was associated with similar early (16.5 vs 15.6%, ns) and late (42.6% vs 32.2%, ns) morbidity rates with a mean follow-up of 25.3 ± 16.6 months compared to primary laparoscopic Roux-en-Y gastric bypass. The revisional RYGB group had significantly less weight loss (mean %EWL 67.4 ± 20.7 vs 72.7 ± 22.9, p = 0.023 and mean %EBMI 68.1 ± 22 vs 78.3 ± 25.7, p = 0.01) at the time of 1 year. Improvement of comorbidities including hypertension (62.5 vs 70.5%; p > 0.05), diabetes (73.7 vs 79%; p > 0.05), and obstructive sleep apnea syndrome (100 vs 97%; p > 0.05) was similar. CONCLUSION: This large case-matched study suggests that conversion of SG or AGB to RYGB is feasible with early and late comparable morbidity in an accredited center; even weight results might be inferior.
