BackgroundConservative obesity treatment often leads to limited results. Bariatric surgery is highly efficient, but the candidates are at risk of developing perioperative complications. Bariatric outcomes have been well described in the past, but there are only few reports of perioperative outcomes.The aim of this study was to evaluate the incidence of anaesthetic and surgical complications of Roux-en-Y bypass.MethodsData of all adult patients, who underwent primary Roux-en-Y gastric bypass surgery between 1/2006 and 12/2013 at the University Hospital Zurich were analysed. Using our clinical database, anaesthetic and surgical complications during the first 30 days after surgery were analysed and risk factors determined by multivariate analysis.ResultsSeven hundred eleven patients (72% female, median age 40 years) were analysed. Overall, surgical complications occurred in 34% patient, while complications attributable to anaesthesia occurred in 37%. Post-operative nausea and vomiting (PONV) were observed in 34%, intubation-related complications in 4%, and delayed extubation in 2% of our patients. Within the first 30 days after surgery, 22% of the patients presented with an infection. Gastrointestinal complications were found in 8%, and bleeding complications in 3%. Anaesthesia complications were less common in older patients and in patients anaesthetized with a volatile anaesthetic. Severe complications were more common in patients with a lower body mass index (BMI) and with longer surgery. The risk to develop a postoperative infection was higher in diabetic patients.ConclusionRoux-en-Y bariatric surgery has few anaesthetic complications, the most common is PONV. PONV is more common in younger patients and not more common with volatile anaesthetics. Major complications are overall rare and occur in patients with lower BMI and longer surgery, likely reflecting more difficult procedures.Electronic supplementary materialThe online version of this article (10.1186/s12871-018-0654-x) contains supplementary material, which is available to authorized users.
The AngioVac® is a vacuum-assisted percutaneous thrombectomy suction system. In critically ill patients, the sudden volume shift can result in abrupt hemodynamic changes thus leading to a cardiac right-left shunt with a high risk of paradoxical embolization. We describe a modified cardiopulmonary bypass circuit for the use of the AngioVac® system that enables full cardiopulmonary support and reduces paradoxical thromboembolic risk.
We report an unusual case of multiple penetrating cerebral, cardiac and abdominal injuries following a suicidal attempt using a nail gun. Successful treatment required several emergency procedures and resulted from a wise interdisciplinary management and timing of surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
