Impact of Laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy on gut microbiota: a metagenomic comparative analysis
Bariatric surgery is an effective therapeutic procedure for morbidly obese patients. The two most common interventions are Sleeve Gastrectomy (SG) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB).
As laparoscopic sleeve gastrectomy (LSG) reaches maturity as a stand-alone bariatric procedure, long-term data continue to evolve regarding its associated outcomes and complication profile. Recent randomized clinical trials have confirmed good if somewhat variable excess weight loss (EWL) at 5 years ranging from 50-80%, generally comparable or slightly inferior to that of roux-en-Y gastric bypass (RYGB).[1-3] Various definitions of success have been proposed, but one of the more commonly utilized metrics requires greater than 50% EWL at 12-18 months following surgery.
Conclusions: There are disparities to access for bariatric surgery in Texas. Blacks have the greatest access followed by whites. Hispanics have the lowest procedure rate per population. PMID: 32425480 [PubMed - in process]
AbstractPurpose of ReviewCurrent bariatric surgical practice has developed from early procedures, some of which are no longer routinely performed. This review highlights how surgical practice in this area has developed over time.Recent FindingsThis review outlines early procedures including jejuno-colic and jejuno-ileal bypass, initial experience with gastric bypass, vertical banded gastroplasty and biliopancreatic diversion with or without duodenal switch. The role laparoscopy has played in the widespread utilization of surgery for treatment of obesity will be described, as will the development of procedures which form th...
In the current manuscript(1), the authors reported the results of the Single Anastomosis Duodeno-Ileal bypass (SADI) and One Anastomosis Gastric Bypass (OAGB) for a cohort of 84 patients who presented with weight loss failure following Laparoscopic Sleeve Gastrectomy (LSG). We especially commend the authors for the interesting topic of their manuscript, as the revisional bariatric surgery after LSG is becoming more common due to the rapid increase in the number of patients undergoing this procedure as treatment for morbid obesity.
Conclusion: GERD may improve in obese patients who underwent laparoscopic sleeve gastrectomy (LSG); however, the most favorable effect is likely to be found after Roux-en-Y gastric bypass surgery. Prospero registration number: CRD42018090074.
AbstractBariatric and metabolic surgery are being performed in India for 2 decades. Aim of this paper is to evaluate the changing clinical trends over the last 5 years and to present the other aspects helmed by Obesity and Metabolic Surgery Society of India (OSSI) to aid the growth of research, education, data management and registry, quality control, insurance-related issues and policy change. OSSI conducts an annual survey to collect data pertaining to numbers of surgical procedures. With the approval of the executive committee, data collected from 2014 to 2018 were retrieved and analysed. 20,242 surgical procedures were...
CONCLUSION: Bariatric surgery might cause reduction of thyroid replacement dosage in hypothyroid, morbidly obese patients. PMID: 32409116 [PubMed - as supplied by publisher]
CONCLUSION: LAGBs are being taken out or converted, and this group makes up the largest portion of revisions and conversions. It is difficult to track SG to LRYGB, but the number of unlisted cases continues to climb. This will likely surpass LAGB conversions with time. The Metabolic and Bariatric Surgery Accreditation Quality Initiative Program should be modified to capture revisions/conversions of SG. PMID: 32299713 [PubMed - as supplied by publisher]
ConclusionsForegut pathology is common in bariatric patients with subjective symptoms of GERD. Implementing a comprehensive protocol to objectively assess these patients leads to a significant clinical impact on which procedure these patients ultimately undergo.
This study included patients who underwent primary laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG). The primary outcome of interest was incisional SSI occurring within 30 days. Surgeries performed in 2015 were used in a derivation cohort and the predictive tool was validated against the 2016 cohort. A forward selection algorithm was used to build a logistic regression model predicting probability of SSI.ResultsA total of 274,187 patients were included with 71.7% being LSG and 28.3% LRYGB. 0.7% of patients had a SSI in which 71.0% had an incisional SSI, and 29.9% had an organ/spa...
