“…The variations of reports in the literature are possibly due to different sample sizes, demographics and variable loss to follow-up rates (50–60%) [ 18 – 21 ]. It is also important to note that during the last decade, we have developed a trend referring patients with higher BMI and poorly controlled obesity related co-morbidities to other procedures (OAGB, RYGB) as they have shown to have satisfactory outcomes [ 22 , 23 ].…”

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 2 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. Graphical Abstract

Background: One anastomosis gastric bypass (OAGB) prevalence is increasing worldwide and shows good mid- to long-term results. Data on long-term outcomes of revisional OAGB (rOAGB) is limited. This study objective is to evaluate the long-term outcomes of patients undergoing primary OAGB (pOAGB) and rOAGB. Methods: A retrospective analysis of a prospectively maintained patient registry at a single-tertiary center. Patients undergoing OAGB from January 2015 to May 2016 were included and grouped to pOAGB and rOAGB. Results: There were 424 patients, of which 363 underwent pOAGB, and 61 underwent rOAGB. Baseline characteristics were insignificantly different between groups except for type 2 diabetes (T2D) rate which was higher in pOAGB (26% vs. 11.5%, p=0.01). The mean follow-up time was 98.5±3.9 months and long-term follow up data was available for 52.5% of patients. The mean total weight loss (TWL) was higher in the pOAGB group (31.3±14 vs. 24.1±17.6, p=0.006), however TWL was comparable when relating to the weight at primary surgery for rOAGB. The rate of T2D and hypertension resolution was 79% and 72.7% with no difference between groups. 13 patients (5.9%) underwent OAGB revision during follow-up, with no difference between groups. Two deaths occurred during follow-up, both non-related to OAGB. Conclusion: OAGB is effective as a primary and as a revisional procedure for severe obesity with good long-term results in terms of weight loss and resolution of associated diseases. In addition, the revisional surgery rates and chronic complications are acceptable. Further large prospective studies are required to clarify this data.
