Predictors of fat-free mass loss 1  year after laparoscopic sleeve gastrectomy

AbstractPurposeLaparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed bariatric surgery interventions because of its safety and efficacy. Nevertheless, concerns have been raised on its detrimental effect on patient nutritional state that can ultimately lead to the loss of fat-free mass (FFM). There is interest in identifying predictors for the early identification of patients at risk of this highly unwanted adverse because they could benefit of nutritional preventive interventions. Therefore, we investigated whether anthropometric parameters, body composition or resting energy expenditure (REE) measured before surgery could predict FFM loss 1  year after LSG.MethodsStudy design was retrospective observational. We retrieved data on body weight, BMI, body composition and REE before and 1  year after LSG from the medical files of 36 patients operated on by LSG at our institutions. Simple regression, the Oldham’s method and multilevel analysis were used to identify predictors of FFM loss.ResultsAveraged percentage FFM loss 1  year after LSG was 17.0 ± 7.7% with significant differences between sexes (20.8 ± 6.6 in males and 12.2 ± 6.1% in females,p

ConclusionDumping syndrome after LSG is prevalent but has not been widely reported. This finding may impact clinicians and patients in their choice of procedure and has relevance in post-operative education and care.

In Canada, 5% of patients are classified as being class II (Body Mass Index [BMI] 35 to 39.9) or class III (BMI ≥ 40) obese. More than 6,500 bariatric surgeries were performed in Canada between 2013-2014, which represents a four-fold increase over seven years. Eighty-five percent of these procedures are either laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG) [1].

Objective: The aim of this study was to assess the safety of revisional surgery to laparoscopic sleeve gastrectomy (LSG) compared to laparoscopic Roux-Y gastric bypass (LRYGB) after failed laparoscopic adjustable gastric banding (LAGB). Background: The number of reoperations after failed gastric banding rapidly increased in the United States during the last several years. A common approach is band removal with conversion to another weight loss procedure such as gastric bypass or sleeve gastrectomy in a single procedure. The safety profile of those procedures remains controversial. Methods: Preoperative characterist...

The objective of this study was to compare rates of postoperative bleeding (POB) among various methods of staple line reinforcement. Methods: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 dataset was queried for patients undergoing an LSG. Patients were stratified by staple line treatment groups-no treatment (NT), suture oversewing (OVERSEW), buttressing by a commercial product (BUTTRESS), and both buttress and oversew (COMBINATION). The primary outcome was POB. Multivariable logistic regression was used to compare POB rates among the treatment groups. Results: In the 98,142...

ConclusionsFindings suggest patients completing surgery within an Appalachian region have successful surgical outcomes at 1-year post-surgery, as indicated by significant reductions of>  50% EWL, regardless of other covariates. Results suggest that bariatric programs should consider paying special consideration to patients with T2D or depressive symptoms to improve outcomes. Results have potential to inform future prospective studies and aid in guiding specific interventions tail ored to address needs of this unique population.

ConclusionsMagnetic-assisted retraction is a novel approach that allows a safe, reproducible, incision-less technique for unconstrained, port-less intra-abdominal mobilization. The device successfully permitted optimal liver retraction during laparoscopic bariatric surgery, enhancing surgical exposure while decreasing the number of abdominal incisions.

ConclusionUDCA for 6  months after bariatric surgery seems to reduce the incidence of gallstone-associated morbidity when compared to the current literature. Thus, our results call the concept of prophylactic concomitant cholecystectomy in patients with asymptomatic gallstones into question while at the same time pavin g the way for a future clinical trial.

CONCLUSION: Younger age, pre-operative alcohol consumption and absence of psychiatric disease were positive predictor factors for successful weight loss after LSG. PMID: 30585171 [PubMed - in process]

AbstractBackgroundObesity is a major health problem in Arab countries. Bariatric surgery can improve the quality of life of an obese individual. However, different types of bariatric surgery result in varying levels of food intolerance as a side effect. Many patients who undergo bariatric surgery are also at risk of subsequently developing eating disorder behaviors. The aim of the study was to compare the quality of life, food tolerance, and behaviors of eating disorders related to laparoscopic sleeve gastrectomy and gastric banding.MethodsA retrospective review of medical records and a questionnaire-based survey was compl...

The optimal timing of pregnancy following bariatric surgery has not been established, with data limited regarding laparoscopic sleeve gastrectomy (LSG). We aimed to explore associations of the surgery-to-conception interval with pregnancy outcomes after LSG.
