Filter by:The purpose of this observational registry is to evaluate the safety and the clinical efficacy of laparoscopic bariatric surgery using stapling devices (easyEndoTM Universal Linear Cutting Stapler and reloads from Ezisurg Medical). The goal of the study will be achieved by reporting peri- and postoperative complications and the clinical outcome after surgery in a prospectively maintained database.
The main objective of this pilot study is to show feasibility to collect peri-operative and postoperative clinical data of the study group of gastric bypass without cholecystectomy compared with the control group of gastric bypass with cholecystectomy. Our hypothesis is that the approach without cholecystectomy would be superior in terms of a decrease of perioperative adverse events and postoperative complications, as well as lenght of operation, lenght of hospital stay, overall costs with a very low risk of biliary complication in the follow up. These findings could be helpful to build a baseline for a future randomized controlled multicenter study allowing significance of these results and help orientate surgeons towards best surgical care of the gallbladder with confirmed absence of stones in the obese patient undergoing gastric bypass.
Obesity is a global public health problem. According to literature reports, as of 2016, China's obese population has reached more than 90 million and type 2 diabetes mellitus has reached more than 100 million, which has brought a serious health and economic burden to China. In addition to various health problems such as cardiovascular, osteoarthritis, and tumors, obesity can also cause abnormalities in reproductive endocrine. In women, it can cause abnormal menstruation, polycystic ovary syndrome, and male obesity can cause secondary gonadal. Hypofunction (MOSH). MOSH is an endocrine dysfunction. It is reported to have a prevalence of approximately 45% in moderate to severe obesity. In addition, studies have pointed out that the prevalence of hypogonadism in men with type 2 diabetes and obesity higher. However, there are no studies on the reproductive function of Chinese male patients after bariatric surgery. Pre- and post-operative semen will be collected for analysis to observe the effect of bariatric surgery on male reproductive function.
