Revisional Surgery After One Anastomosis/Minigastric Bypass: an Italian Multi-institutional Survey.

BACKGROUND: Efficacy and safety of OAGB/MGB (one anastomosis/mini gastric bypass) have been well documented both as primary and as revisional procedures. However, even after OAGB/MGB, revisional surgery is unavoidable in patients with surgical complications or insufficient weight loss. METHODS: A questionnaire asking for the total number and demographics of primary and revisional OAGB/MGBs performed between January 2006 and July 2020 was e-mailed to all S.I.C. OB centres of excellence (annual caseload > 100; 5-year follow-up > 50%). Each bariatric centre was asked to provide gender, age, preoperative body mass index (BMI) and obesity-related comorbidities, previous history of abdominal or bariatric surgery, indication for surgical revision of OAGB/MGB, type of revisional procedure, pre- and post-revisional BMI, peri- and post-operative complications, last follow-up (FU). RESULTS: Twenty-three bariatric centres (54.8%) responded to our survey reporting a total number of 8676 primary OAGB/MGBS and a follow-up of 62.42 ± 52.22 months. A total of 181 (2.08%) patients underwent revisional surgery: 82 (0.94%) were suffering from intractable DGER (duodeno-gastric-esophageal reflux), 42 (0.48%) were reoperated for weight regain, 16 (0.18%) had excessive weight loss and malnutrition, 12 (0.13%) had a marginal ulcer perforation, 10 (0.11%) had a gastro-gastric fistula, 20 (0.23%) had other causes of revision. Roux-en-Y gastric bypass (RYGB) was the most performed revisional procedure (109; 54%), followed by bilio-pancreatic limb elongation (19; 9.4%) and normal anatomy restoration (19; 9.4%). CONCLUSIONS: Our findings demonstrate that there is acceptable revisional rate after OAGB/MGB and conversion to RYGB represents the most frequent choice.

Three years durability of the improvements in health-related quality of life observed after gastric banding.

BACKGROUND: Improvements in health-related quality of life (HR-QoL) occur after bariatric surgery. However, sustainability of these changes over time remains debated. METHODS: Data collected in a prospective 3-year multicenter Italian study on changes of HR-QoL after laparoscopic adjustable gastric banding were used. HR-QoL has investigated with the SF-36 questionnaire. Hunger, satiety, and the self-perceived effects of LAGB were recorded. RESULTS: A total of 230 patients (53 male and 177 female) were analyzed. Body mass index was 41.4±5.4 kg/m2 at baseline, declined to 33.8±5.8 kg/m2 12 months after surgery (P<.001), and further reduced to 31.9±5.1 kg/m2 36 months after surgery (P<.001 versus 12 months). Scores in the SF-36 subscales were lower than in the general Italian population at baseline. The physical component summary score was 51.9±11.6 at baseline, improved to 79.2±15.4 at 12 months (P<.001), and stabilized to 79.8±15.6 at 36 months. The mental summary score was 52.3±11.8 at baseline, improved to 75.2±17.3 at 12 months (P<.001), and stabilized to 74.2±17.5 at 36 months. A decline>10 points between 12 and 36 months in the summary scores was observed in 22.0% of the patients for PCS and in 26.8% for MCS. In a multiple linear regression analysis, deterioration in HR-QoL in the 12-36 months period was associated to the presence of better HR-QoL values at 12 months and to a more pronounced reduction of the self-perceived effect of the banding at 36 months. CONCLUSION: Improvements in HR-QoL observed in the first year after surgery maintained up to the third year after gastric banding.
