Roux-en-Y gastric bypass is safe in elderly patients: a propensity-score matched analysis.

ABSTRACT: BACKGROUND:Numerous studies have established the effectiveness of Roux-en-Y gastric bypass (RYGB) for weight loss and co-morbidity amelioration. However, its safety and efficacy in elderly patients remains controversial. OBJECTIVES:To evaluate outcomes in patients aged ?60 years who underwent RYGB compared with nonsurgical controls with the hypothesis that RYGB provides weight loss benefits without differences in survival. SETTING:University-affiliated tertiary center. METHODS:All patients who underwent RYGB from 1985 to 2015 were identified and divided into elderly (age ?60) and nonelderly (age <60) groups. A nonsurgical elderly control population was identified using a clinical data repository of outpatient visits to propensity match elderly patients 4:1 on demographic characteristics, co-morbidities, and relevant preoperative substance/medication use. Unpaired appropriate univariate analyses compared each stratified group. Kaplan-Meier survival curves were fitted based on social security death data. RESULTS:A total of 2306 patients underwent RYGB. The 107 elderly patients had lower median body mass index (47.0 versus 49.9; P?=?.007) and higher rates of co-morbidities. Rates of complications did not differ between elderly and nonelderly patients. Elderly surgical patients were propensity matched 4:1 (10,044 controls) yielding 428 well-matched nonsurgical controls. The elderly group demonstrated significant percent reduction in excess body mass index compared with the control group (81.8% versus 10.3%; P < .001). Kaplan-Meier survival analysis with log-rank test demonstrated no difference in midterm survival (P?=?.63). CONCLUSIONS:A significant weight reduction benefit was identified after RYGB in elderly patients without a difference in midterm survival compared with propensity-matched controls, suggesting RYGB is a safe and efficacious weight loss strategy in the elderly.

Project description:BACKGROUND:There is a paucity of data comparing 30-day morbidity and mortality of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB). This study aimed to compare the 30-day safety of SG, RYGB, and OAGB in propensity score-matched cohorts. MATERIALS AND METHODS:This analysis utilised data collected from the GENEVA study which was a multicentre observational cohort study of bariatric and metabolic surgery (BMS) in 185 centres across 42 countries between 01/05/2022 and 31/10/2020 during the Coronavirus Disease-2019 (COVID-19) pandemic. 30-day complications were categorised according to the Clavien-Dindo classification. Patients receiving SG, RYGB, or OAGB were propensity-matched according to baseline characteristics and 30-day complications were compared between groups. RESULTS:In total, 6770 patients (SG 3983; OAGB 702; RYGB 2085) were included in this analysis. Prior to matching, RYGB was associated with highest 30-day complication rate (SG 5.8%; OAGB 7.5%; RYGB 8.0% (p = 0.006)). On multivariate regression modelling, Insulin-dependent type 2 diabetes mellitus and hypercholesterolaemia were associated with increased 30-day complications. Being a non-smoker was associated with reduced complication rates. When compared to SG as a reference category, RYGB, but not OAGB, was associated with an increased rate of 30-day complications. A total of 702 pairs of SG and OAGB were propensity score-matched. The complication rate in the SG group was 7.3% (n = 51) as compared to 7.5% (n = 53) in the OAGB group (p = 0.68). Similarly, 2085 pairs of SG and RYGB were propensity score-matched. The complication rate in the SG group was 6.1% (n = 127) as compared to 7.9% (n = 166) in the RYGB group (p = 0.09). And, 702 pairs of OAGB and RYGB were matched. The complication rate in both groups was the same at 7.5 % (n = 53; p = 0.07). CONCLUSIONS:This global study found no significant difference in the 30-day morbidity and mortality of SG, RYGB, and OAGB in propensity score-matched cohorts.

Project description:Performing endoscopic retrograde cholangiopancreatography in bariatric patients who underwent Roux-en-Y gastric bypass surgery is challenging due to the long anatomical route required to reach the biliopancreatic limb.Assessment of the feasibility and performance of laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography.A retrospective multicenter observational consecutive-patient cohort study of all patients in the period May 2008 to September 2014 with a history of Roux-en-Y gastric bypass who presented with complicated biliary disease and who underwent a laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography. The laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography procedure was similar in all centers and was performed through a 15 mm or 18 mm trocar that was inserted in the gastric remnant. Cholecystectomy was performed concomitantly when indicated.In total, 23 patients underwent a laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography procedure. Two patients required a mini-laparotomy for transgastric access because of a complex surgical history resulting in multiple adhesions. Indications included ascending cholangitis, choledocholithiasis, and biliary pancreatitis. Of the 23 patients, 13 underwent concomitant cholecystectomy. All patients successfully underwent biliary cannulation and sphincterotomy. No endoscopic procedure-related complications (i. e. bleeding, pancreatitis or retroperitoneal perforation) occurred. Mean hospital stay was 2.8 days (range 2 - 4).Transgastric endoscopic retrograde cholangiopancreatography is a feasible approach in the treatment of pancreaticobiliary disease in Roux-en-Y gastric bypass patients, without major complications in our series and allows endoscopic treatment and cholecystectomy to be performed consecutively in a single procedure. In Roux-en-Y gastric bypass patients without a history of prior cholecystectomy presenting with complicated gallstone disease, combining cholecystectomy and transgastric endoscopic retrograde cholangiopancreatography as a first-line approach may be a valid treatment strategy.
