Age- and sex-specific effects on weight loss outcomes in a comparison of sleeve gastrectomy and Roux-en-Y gastric bypass: a retrospective cohort study

Objective: The impact of extended antral resection (AR) after laparoscopic sleeve gastrectomy (LSG) on clinical results is still not clearly elucidated with conflicting results. Our study aimed to determine whether AR is superior to antral preservation (AP) regarding clinical results. Methods: Patients were divided into two groups according to the distance of gastric division as AR group (2cm from pylorus) and AP group (6cm from pylorus). Postoperative excess weight loss percentile (%EWL) and total body weight loss percentiles (%TBWL) at the end of first, 6th and 12 months were compared. Secondly, metabolic parameters and complications were compared. Results: The first 68 patients underwent AP, and the following 43 patients underwent AR. Although statistically not significant, AR achieve more %EWL and %TBWL at the end of the first year, (P>0.05). On the other hand, metabolic parameters were similar at the end of the first year, (P>0.05). Resolution of comorbidities were statistically not different, (P>0.05). Staple line leak occurred in two patients of the AR group (4.7%) and two patients of the AP group (2.9%), (P>0.05). Conclusion: Both AR and AP seem to be equally effective in resolution of metabolic response. Although statistically not significant- AR provided more %EWL and %TBWL at the end of 12 months. doi: https://doi.org/10.12669/pjms.36.6.2321 How to cite this:Yuksel A, Coskun M, Karaman K.

Abstract Background and Objective: Bariatric surgery has been recognized as the most effective long-term treatment for morbid obesity. Despite the considerable positive results, adverse consequence can develop. Excessive Weight Loss (EXWL), a rare consequence of bariatric surgery, can lead to a broad adverse consequence. The aim of this study was determining of prevalence and the predicting model of EXWL in patient underwent bariatric surgery until 24 months after surgery.Material and Methods: Data have been extracted from the National Obesity Surgery Database in obesity clinic of * University of Medical Sciences. The subjects of this retrospective cohort study were morbid obese individuals who underwent three various types of bariatric surgery (One Anastomosis Gastric Bypass (OAGB), Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG)) in period of 24 months ago. EXWL has been defined as excess weight loss more than 100% at any time until 24 months after surgery. SPSS (version 23) was used in data analysis.Results: Among 4214 subjects of this study, most excess weight loss after surgery has taken place in 18 months after surgery. 18.5% (n=407) of patients experienced EXWL with highest percentage among OAGB patients (22.6%). The females (20.4% vs.9.9%) and younger persons (35.45 ± 10.25 vs. 39.06 ± 10.76) were more susceptible to EXWL. patients with EXWL had significantly lower BMI (body mass index) (41.11± 4.51 vs. 46.73±6.26) (Kg/m2), and were less probable to had emotional eating. Visceral fat level, fat percentage and BMI were the best predictor of EXWL (P-value for all <0.05).Conclusions: Surgery should be adjusted in younger females with a lower BMI and healthy metabolic status who are more prone to EXWL. In such a way that minimize weight loss speed/value. It may be possible by selection of other surgery procedures, rather than OAGB, tighter follow ups and consultations of patients after surgery is emphasized for more EXWL vulnerable patients.
