    Abstract:
    BACKGROUND: The previous popularity of adjustable gastric banding (AGB), along with inconsistent long-term results, has resulted in the need for conversion to other procedures. The perioperative safety of laparoscopic sleeve gastrectomy (SG) and gastric bypass (RYGB) as single-stage conversion procedures is unclear. OBJECTIVES: To compare the early safety of SG and RYGB when performed as single-stage conversion procedures at the time of AGB removal. SETTING: Nationwide analysis of accredited centers. METHODS: The Metabolic and Bariatric Surgery Accreditation Quality and Improvement Program public use file for 2015 was queried for all patients who underwent single-stage conversion to SG or RYGB. Multivariable logistic regression was performed to control for baseline differences, and odds ratios (ORs) with 95% confidence intervals are reported. RESULTS: There were 4865 patients who underwent a single-stage AGB conversion. SG was performed in 3364 (69.1%). The 30-day reoperation (1.6% versus 2.7%, P = .008), readmission (4% versus 5.7%, P = .006), reintervention (1.7% versus 2.7%, P = .024), and overall morbidity (2.9% versus 6.5%, P<.0001) were significantly less common in the SG group. After controlling for baseline characteristics, RYGB was independently associated with higher overall 30-day reoperation (OR 1.81, 1.19-2.75), readmission (OR 1.42, 1.07-1.88), reintervention (OR 1.59, 1.06-2.4), and overall morbidity (OR 2.17, 1.62-2.9). CONCLUSIONS: AGB conversions are associated with low overall 30-day event rates. Patients undergoing RYGB as a single-stage conversion experience higher complication rates and the need for additional early procedures compared with SG.
