Five-year results of sleeve gastrectomy. 2013
OBJECTIVE Our purpose was to evaluate the efficacy and safety of sleeve gastrectomy (SG) at 5 years after surgery. METHODS From June 2005 to January 2007, 65 obese patients underwent SG. The percentage of excess weight loss (%EWL) and excess BMI loss (% EBL), obesity-related co-morbidities, and post-SG complications were evaluated at 2 years after SG based on our database, and at 5 years after SG based on a questionnaire sent to the patients by one of the authors (IB) between May 2011 and February 2012. RESULTS A complete data set was obtained for 53 of 65 patients (82%), including 45 patients who had SG as the only surgical treatment, and eight patients who had a second bariatric procedure at a later date because of insufficient weight loss (five gastric bypass (GBP), three SG revision). For these 53 patients, the mean %EWL was 54.4% at 2 years and 53.7% at 5 years, and the mean %EBL was 61% at 2 years and 60% at 5 years. Three patients (5.7%) had post-operative complications (two fistulas (3.8%), one hemorrhage (1.9%)). Three trocar-site hernias (5.7%) were observed between 10 months and 34 months post-SG. Sub-group analysis of the 45 patients who underwent SG alone showed a mean %EWL of 57.1% at 2 years and 50.7% at 5 years; the mean %EBL was 64% at 2 years and 56.8% at 5 years. Of these 45 patients, 13 (28.9%) required medication to treat diabetes (DM) before SG and only five (11.1%) at 5 years after SG (61.5% decrease); 18 (40%) had antihypertensive treatment before SG, and eight (17.8%) at 5 years after SG (55.5% decrease); 12 (26.7%) took lipid-lowering medication before SG, and five (11.1%) at 5 years after SG (58.3% decrease); 24 (53.3%) had sleep apnea (SAS) before SG and six (17.8%) at 5 years after SG (75% decrease). However, while only five patients (11.1%) had GERD requiring PPI therapy before SG, 15 patients required PPI therapy (33.3%) at 5 years after SG (200% increase). CONCLUSIONS Five years after performance of SG, weight loss was satisfactory, few complications were observed, the reduction of co-morbidities was significant, but there was an increase in the frequency of GERD.
