Active clinical trials for "Gallstones"

in this study we compare the results of concomitant cholecystectomy with bariatric surgery versus delayed cholecystectomy for management of gallstone in obese patients

Many options are available for management of common bile duct stones. the most recent development in this field is single-session approach by one of two methods; laparoscopic common bile duct exploration and intraoperative endoscopic sphincterotomy. In this study, the investigators prospectively compare these two methods for management of patients with preoperatively diagnosed common bile duct stones to settle the best option.

ERCP plays an important role in management of common bile duct stones. Herein the investigators compare preoperative against intraoperative ERCP. 210 were included but only 198 patients were randomly divided into two groups; PES/LC (100 patients) and LC/IOES (98 patients). The total hospital stay were significantly shorter in the group of LC/IOES

Case matched study on 50 consecutive patients undergoing robotic assisted cholecystectomy (Da Vinci Robot, Intuitive Surgical). These patients are matched 1:1 to 50 patients with conventional laparoscopic cholecystectomy, according to age, gender, ASA score, histology and surgical experience. Trial with surgical intervention

The 3D-systems have emerged also to the world of surgery, and the three-dimensional laparoscopic systems are gradually entering the operating rooms. In the normal laparoscopy there are only two-dimensional view, which is somewhat challenging when operating in three-dimensional environment. Even though the 3D-systems have been widely studied in laboratory circumstances, there are still no evidence of benefits of 3D vs 2D in clinical point of view and no prospective randomized trials have been published. Therefore, the purpose of this study is to investigate is there something to gain in changing into 3D laparoscopic system for cholecystectomy (LCC).

Minlaparotomy (MC) and laparoscopic cholecystoctomy (LC) are commonly applied surgical techniques for the management of symptomatic gallstone disease and both techiques have shown to be feasible for day surgery. However, to our knowledge the long-term outcome between these approaches has not been compared in randomised trials as day surgery procedures.

This study is designed to assess whether a new technique called facilitated endoscopic retrograde cholangiopancreatography (ERCP) is or is not superior to conventional ERCP for removing stones found in the bile duct at the time of laparoscopic cholecystectomy. ERCP is an endoscopic procedure used to facilitate the radiological examination and subsequent manipulation of the common bile duct (eg. opening it up, which is called sphincterotomy). Both facilitated and conventional ERCP are performed as a separate procedure after the initial gallbladder surgery. This is a comparative study of these two techniques in a randomised clinical trial. The aim of this randomised clinical trial is to enable surgeons to decide whether placement of a plastic stent at the time of laparoscopic cholecystectomy will improve the success rate and safety of subsequent ERCP and sphincterotomy.

In laparoscopic cholecystectomy method, Insufflation of CO2 in abdominal cavity causes positioning of the diaphragm upwards, a decrease in lung's volume and its compliance, an increase in the airway resistance, mismatch between the atelectasis and the ventilation perfusion. Although there are numerous studies in laparoscopic surgery, only a few of them investigate the effects of laparoscopic surgery on the cardiopulmonary and the respiratory mechanics. The investigator aimed To examine the effects of pressure-controlled and volume-controlled ventilation modes on cerebral oximetry and blood gases in laparoscopic cholecystectomy operations.

The objective of this study is to determine if IV acetaminophen administered intraoperatively can decrease the dose of narcotics required for adequate pain control and shorten recovery time in the PACU specifically in obese patients at risk for obstructive sleep apnea.

The investigators hypothesize that the da Vinci Fluorescence Imaging Vision System provides real-time endoscopic near infrared fluorescence imaging of the biliary anatomy as defined as identifying biliary vessels; either cystic duct, common hepatic duct (CHD) or common bile duct (CBD). Irradiation given to the patient during a classic cholangiography can be reduced.
