https://www.selleckchem.com/products/AZD0530.html Small bowel intussusception is a rare complication after Roux-en-Y gastric bypass, with few cases reported, and none in the immediate post-operative period of an abdominoplasty. We report the case of a 42-year-old woman, with an history of a laparoscopic Rouxen-Y gastric bypass, who developed small bowel occlusion secondary to a retrograde jejunojejunal intussusception in the second post-operative day of an abdominoplasty. This is the first report of a small bowel intussusception after Roux-en-Y gastric bypass in the post-operative period of an abdominoplasty. Doubts remain about the possible causal effect abdominoplasty might have in small bowel intussusception after Roux-en-Y gastric bypass. Although laparoscopic cholecystectomy is an increasingly performed technique in the outpatient setting, it is not done in some Units due to lack of overnight stay. The objectives of this study are to identify the differences between patients with discharge at the end of the day versus overnight stay and the factors predicting overnight stay. A retrospective analysis of the pre, peri and postoperative data of patients operated between January/2014 and December/2017 was performed, and a statistical analysis of the variables. A total of 311 patients were included, 33.4% of whom stayed overnight. Of these, 81.7% were operated after 2pm. As predictors factors of overnight stay, the age (p = 0.001) was identified in the morning group, with a greater possibility of overnight stay (15.3%) from 61.50 years (Younden index = 0.396) and the surgery start time (p < 0.0001) in the afternoon group, with a greater possibility of overnight stay (77.1%) from 430 pm (Younden index = 0.492). Most patients stayed overnight due to the time at which recovery was completed, since no cause was identified (84.7%). If our unit would not have an overnight stay we would have an overall hospitalization rate of 8.4%, which corresponds to patients with an ide
