The aim of this study was to evaluate the mid-term outcomes of the laparoscopic ileal interposition associated to a sleeve gastrectomy (LII-SG) for the treatment of morbid obesity. The procedure was performed in 120 patients: 71 women and 49 men with mean age of 41.4 years. Mean body mass index (BMI) was 43.4 +/- 4.2 kg/m(2). Patients had to meet requirements of the 1991 NIH conference criteria for bariatric operations. Associated comorbidities were observed in all patients, including dyslipidemia in 51.7%, hypertension in 35.8%, type 2 diabetes in 15.8%, degenerative joint disease in 55%, gastroesophageal reflux disease in 36.7%, sleep apnea in 10%, and cardiovascular problems in 5.8%. Mean follow-up was 38.4 +/- 10.2 months, range 25.2-61.1. There was no conversion to open surgery nor operative mortality. Early major complications were diagnosed in five patients (4.2%). Postoperatively, 118 patients were evaluated. Late major complications were observed in seven patients (5.9%). Reoperations were performed in six (5.1%). Mean postoperative BMI was 25.7 +/- 3.17 kg/m(2), and 86.4% were no longer obese. Mean %EWL was 84.5 +/- 19.5%. Hypertension was resolved in 88.4% of the patients, dyslipidemia in 82.3%, and T2DM in 84.2%. The LII-SG provided an adequate weight loss and resolution of associated diseases during mid-term outcomes evaluation. There was an acceptable morbidity with no operative mortality. It seems that chronic ileal brake activation determined sustained reduced food intake and increased satiety over time. LII-SG could be regularly used as a surgical alternative for the treatment of morbid obesity.
