Ten-Year Results of Laparoscopic Sleeve Gastrectomy: a Retrospectively Designed Study of a Single Tertiary Center.

Purpose: Laparoscopic sleeve gastrectomy (SG) is the most popular bariatric surgery. Nonetheless, only a few studies have reported its long-term outcomes. This study aimed to evaluate changes in weight and body mass index (BMI) parameters, resolution of comorbidities, and frequency of re-operations in a follow-up period of at least 10 years.

Materials And Methods: Data was available from 180 patients' records who underwent SG between 2008 and 2011 in the Tel Aviv Sourasky Medical Center. Eighty patients agreed to partake in a follow-up assessment that was completed via a phone call questionnaire and hospital computed registry.

Results: Patients' mean preoperative BMI was 43.86 ± 6.36 kg/m which was significantly higher when compared to mean nadir BMI and last follow-up BMI (29.44 ± 7.12 and 36.34 ± 9.7; p < 0.001). Mean percentage of excess weight loss (%EWL) at 10 years was 42.65 ± 36.02% and mean percentage of total weight loss was 19.33 ± 16.73%. Twenty-eight patients (35%) maintained at least 50% EWL. Twenty-seven (33.75%) patients underwent at least one surgical procedure following SG. Eleven patients (13.75%) underwent a conversion to Roux-en-Y gastric bypass and six patients (7.5%) underwent conversion to one anastomosis gastric bypass. Resolution of type 2 diabetes (T2D), hypertension, and hypercholesterolemia occurred in 47%, 43.7%, and 48.4%, respectively. De-novo cases of gastroesophageal reflux (GERD) were present in 40%.

Conclusion: SG shows high long-term failure rates. One of every three patients will undergo another surgical procedure within a 10-year period.
