Early Postoperative Complications in Roux-en-Y Gastric Bypass

Abstract

Background: Roux-en-Y gastric bypass is one of the most common bariatric surgery and leads to considerable weight loss in the first months. Aim: To quantify the main early postoperative complications in patients submitted to the gastric bypass. Method: Observational retrospective cohort. Data of 1051 patients with class II obesity associated with comorbidities or class III obesity submitted to the gastric bypass with 30 days of follow-up starting from the date of the surgery. Results:The age average was 36 years with a predominance of females (81.1%). The mean preoperative body mass index was 43 kg/m². The major complication was fistula (2.3%), followed by intestinal obstruction (0.5%) and pulmonary embolism (0.5%). Death occurred in 0.6% of the cases. Conclusion:In the period of 30 days after surgery the overall complication rate was 3.8%; reoperation was necessary in 2.6% and death occurred in 0.6%. Fistula was the main complication and the leading cause of hospitalization in intensive care unit, reoperation and death.

Cirurgias bariátricas realizadas pelo Sistema Único de Saúde no período 2010-2016: estudo descritivo das hospitalizações no Brasil*

“…We found 0.2% in-hospital lethality among patients admitted for bariatric surgery over the period analyzed Bariatric surgery in Brazil (2010)(2011)(2012)(2013)(2014)(2015)(2016) and this was similar to the rates found by several other studies. 9,14,15,17,18,20 When comparing inhospital lethality (0.2%) for the period 2010-2016 found in our study with that found for the period 2003-2009 (0.6%) and reported by Kelles, Machado and Barreto, 9 it can be stated that a considerable reduction occurred.…”

“…16 Despite there not being significant differences in obesity prevalence between males and females in Brazil -18.1% versus 19.6% respectively -, the predominance we found for female bariatric surgery hospitalizations (85.4%) is compatible with other studies. 9,[17][18][19][20][21] A possible explanation for higher frequencies of bariatric surgery among females may be related to the fact of women being more concerned than men about their physical appearance. Esthetic motivation favors the quest for this form of surgery as a way for women to fit in with the standards of beauty imposed by the media and society.…”

Comparative analysis between patients undergoing Gastric Bypass and Sleeve Gastroplasty in a private hospital in Sao Luis-MA

“…In the analysis of postoperative side effects, other studies 19,38 had similar results, since nausea and vomiting were listed as one of the most frequent alterations found, besides hair loss and nutritional deficiency. As seen in the present study, as well as those found in the literature, postoperative changes are frequent, requiring health professionals to be prepared to make early diagnosis and intervention, to attenuate the impact on patients' health and quality of life, thus achieving better results 19,39 .…”

“…Postoperative complications of RYGB can be divided into early and late. Early complications, defined as those which occur within 30 days of the operation, include fistula, bowel obstruction, and pulmonary embolism [ 5 ]. Late complications include strictures, enteric fistulas, cholelithiasis, marginal ulcers, ventral and internal hernias leading to small bowel obstruction, dumping syndrome, gastric remnant distension, and nutritional deficiencies [ 6 , 7 ].…”
