WEIGHT LOSS AFTER LAPAROSCOPIC SLEEVE GASTRECTOMY: THE 4-YEARS EXPERIENCE AT MAGGIORE DELLA CARITÀ HOSPITAL (NOVARA, PIEDMONT)

Abstract

Bariatric surgery is currently considered the most effective longterm treatment to obtain substantial and sustained Weight Loss (WL) in severe and/or morbid obesity. We present data collected by a multi-disciplinary team between July 2016 and September 2020 at “Maggiore Della Carità” University Hospital (Novara, Piedmont) concerning bariatric procedures performed according to international and national guidelines (1). Among 267 candidates, 92 (34,4%) subjects underwent a bariatric procedure. Laparoscopic Sleeve Gastrectomy (LSG) was performed in 66 (71.7%) subjects, including 4 anti-reflux valves. Other procedures included: 7 (10.6%) Roux-Y Gastric Bypass, 4 (6.1%) Endoscopic Gastric Plication, and 10 (15.2%) Laparoscopic Adjustable Gastric Banding Removal. Among LSG, 35 patients completed at least a 2-year follow-up after surgery: 27 (77.1%) females, 8 (22.9%) males, mean age 44,89 (± 10.1) years old. Table 1 shows significant variations from baseline (p<0.05) after 1, 6, 12, and 24 months observed for body weight, BMI, excess weight, waist circumference, and serum glucose levels. Among complications, no severe adverse events were recorded. Two gastric fistulas were successfully treated by endoscopy. In our multidisciplinary experience, LSG was effective to achieve and maintain a significant weight loss and to improve glucose levels up to 2 years after surgery. Larger cohorts and longer period data will provide further concerns in terms of maintenance, insulin resistance, and long-term metabolic complications decrease.
