Abstract

Objective: To assess the 10-year outcomes after sleeve gastrectomy (SG). Primary end-points were the long-term weight loss and the need for conversion and one of the secondary end-points was the incidence of gastroesophageal reflux (GERD).

Materials and methods: Between 2006 and 2008, 40 consecutive patients had a primary SG. A retrospective analysis of our database and telephone interview of patients who defaulted clinic follow-up was conducted. Success of surgery was defined as percentage of excess weight loss (%EWL) > 50% and no need for conversion.

Results: Thirty-four patients (85%) achieved a 10-year follow-up. There were 11 men and 23 women with a mean preoperative body mass index (BMI) of 44 ± 4 kg/m2 and a mean age of 42 ± 8 years. Optimal weight loss was reached after a follow-up of 12 months: the mean BMI was 31 ± 5 kg/m2 and %EWL 70 ± 21%. A progressive weight regain was observed over time. With a median follow-up of 11 years (range 7-12), the mean BMI and %EWL were respectively 36 ± 8 kg/m2 (p < 0.005) and 42 ± 37% (p < 0.001). With a median delay of 9 years (range 7-9), 6 patients (18%) were converted to gastric bypass because of weight regain. On total, SG was successful only in 14 patients (41%). Success rate was particularly high in patients who had a 1-year %EWL > 75%: 10/12 (83%) vs. 4/22 (17%) (p < 0.001). Those 12 patients were only characterized by a lower preoperative BMI: 41 ± 2 vs. 45 ± 4 (p < 0.002). Besides, 22 patients (65%) had long-term GERD requiring medical treatment: the incidence of de novo GERD was 41% (6/14) and of persisting GERD 80% (16/20).

Conclusions: Our 10-year success rate after SG was 41% and the incidence of GERD 65%. SG should preferably be proposed to selected patients. Patients with low preoperative BMI and without preoperative symptoms of GERD appeared as the best candidates for SG.
