Sleeve gastrectomy (SG) has been originally conceived as a first step procedure for super obese (SO) patients, but it is currently considered a stand-alone intervention. Medium-term to long-term studies have shown weight regain and risk of de novo gastroesophageal reflux (GERD). The aim of this study was to evaluate outcomes of SG in SO subjects.A retrospective analysis of a prospectively maintained database was carried out to find all SO patients who had undergone SG with a minimum follow-up of 5 years. Inclusion criteria were preoperative endoscopy negative for esophagitis and/or hiatal hernia, and no GERD or acid reduction medication before SG. Reflux symptoms were evaluated using a validated questionnaire and endoscopy. Remission rates from comorbidities and percentage of excess body mass index (BMI) loss were recorded.A total of 66 (45 male/21 female) patients were included in our study. Mean preoperative BMI and age were 57.4±5.8 kg/m2 and 32.7±11.2 years, respectively. After 5 years, mean percentage of excess BMI loss was 56.42±27.8, and remission rates from hypertension, diabetes, and dyslipidemia were 33.3%, 5.3%, and 20%, respectively. After 5 years, new-onset GERD occurred in 66.7% of patients and 33.3% were taking acid reduction medication. Endoscopy revealed 12 (18.2%) cases of esophagitis ≥grade A.After 5 years, weight loss in SO patients is satisfactory, but the vast majority of patients is still in class II obesity, and resolution of comorbidities is disappointing. High rates of de novo GERD and esophagitis may occur.
