      Abstract

      Background

      The stomach, intestinal, and pylorus-sparing (SIPS) procedure is a single-anastomosis duodeno-intestinal bypass used in obesity management.

      Objective

      Weight and metabolic outcomes in patients with severe obesity who underwent the SIPS procedure were evaluated in a community hospital–based study.

      Setting

      Community hospital.

      Methods

      This single-site prospective study of patients who underwent the SIPS procedure evaluated outcomes at 12 and 24 months. Mean changes in total weight loss and body mass index (BMI) and resolution of gastroesophageal reflux disease (GERD), obstructive sleep apnea (OSA), hypertension, type 2 diabetes (T2D), and hyperlipidemia were evaluated.

      Results

      At baseline, 185 patients were enrolled; mean weight and BMI were 144.0 kg and 52.2 kg/m2, respectively. Data for 88 (47.6%) and 29 (15.7%) patients who completed follow-up at 12 and 24 months, respectively, were available. At 12 months, mean total weight loss was 35.6% (weight reduction of 51.3 kg) and BMI reduction of 17.8 points were achieved and were maintained for the 29 patients who completed 24-month follow-up. No leaks or infections occurred. Complications occurred in 8 patients (.4%) and were not serious. Resolution of GERD, OSA, hypertension, T2D, and hyperlipidemia achieved in 87.1%, 59.2%, 32.7%, 93.1%, and 87.6% of patients, respectively, at 12 months was maintained at 24 months. Nutritional deficiency was absent.

      Conclusions

      Patients who underwent the SIPS procedure had meaningful reductions in weight and BMI, and many had resolution of metabolic co-morbidities; procedural complication rates were low. Our results support that the SIPS procedure is a safe and effective primary treatment for clinically severe obesity in a community-based hospital setting.
