External warming is routinely used in general surgery to offset the deleterious effects of hypothermia. It entails deployment of a disposable, external heating blanket attached to a regulated hot-air pump. The need for external warming in the morbidly obese population undergoing short laparoscopic procedures is unclear. If proven to be unnecessary, time and momentary costs could be lowered. The study will compare core-temperature dynamics during laparoscopic bariatric procedures anticipated to last <2h. The study group will be left without a warming blanket while the control group will receive routine external warming. Post-anesthesia care unit (PACU) arrival temperature will also be recorded.
The present study aims to explore the impact of combining laparoscopic greater curvature plication with a single gastro-ileal anastomosis in the same manner of single anastomosis sleeve ileal bypass on weight loss and postoperative complications. The objective of this combined procedure is to reduce the high intraluminal pressure that results after laparoscopic greater curvature plication owing to reduced intraluminal space which can lead to suture line leakage, vomiting, and gastroesophageal reflux disease. Another objective is to add a malabsorptive element to the restrictive effect of laparoscopic greater curvature plication and to induce early satiety in patients by distention of the distal bowel with nutrients immediately after meals, similar to the way that single anastomosis sleeve ileal bypass works.
The aim of our study is to evaluate the efficacy of "60 meters 60 seconds exercise test" (a test designed by the study group) done preoperatively as a predictor test for postoperative intensive care unit need and extubation success in patients undergoing bariatric surgery.
Patients undergoing bariatric surgery will be divided randomly into two groups: the first will have TAP block upon completion of surgery and the second groups will not have TAP block.
The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on oesophageal symptoms and disease, including the presence of Barrett oesophagus ≥ 5 years post-surgery.
The goal of this trial is to examine long-term effects of laparoscopic gastric bypass (LRYGB) and sleeve gastrectomy (LSG) on bone mineral density, fracture risk, and body composition ≥ 5 years post-surgery.
Obesity is an increasing world wide problem. Moreover, the increase in patients who are considered morbidly obese is even higher (Sturm et al, Healt Aff 2004). Conservative approaches such as diets or medication are unsuccessful in the majority of the patients. Additionally, (morbid) obesity leads often to cardiovascular diseases, such as hypertension, dyslipidemia and type 2 diabetes (T2DM). When patients need insulin to regulate their glucose levels, their weight is even more difficult to control. Therefore, bariatric procedures are increasingly performed, with over 8.000 procedures in the Netherlands in 2013. The two most performed types of bariatric surgery in the Netherlands are the Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) and the Laparoscopic Sleeve Gastrectomy (LSG). Within the LRYGB there are different variants available. In a recently initiated randomized controlled trial (RCT) from our centre, a comparison between two variants of RYGB was performed. In this RCT our standard RYGB (s-RYGB:alimentary limb (AL) of 150cm; biliopancreatic limb (BPL) of 75cm) was compared with a RYGB with an long BPL (LBPLRYGB:AL of 75cm and a BPL of 150cm). A LBPLRYGB might improve weight loss and reduction after surgery. The exact mechanism of action is still not fully understood. Stomach volume is decreased and satiety levels often increase, probably due to changes in incretin levels. Passage of foods through the gastrointestinal tract are altered after RYGB. A possible explanation might be found in different levels of incretins (such as GLP-1, PYY and ghrelin) and bile acids (FGF-19 and FGF-21) after bariatric surgery.
The correlation between metabolic syndrome and carotid artery stenosis is well established. The purpose of this study is to evaluate the relationship between morbid obesity and carotid artery stenosis.
he purpose of this study is to study the effect of preoperative PPI in the early outcome of sleeve gastrectomy
This study investigates the chronic long-term health condition of obesity and its effect on neutrophil function and the inflammatory response
