Active clinical trials for "Gallstones"

The purpose of this study is to evaluate the safety and feasibility of the Levita Dual Robotic Arm Accessory (DRAA) used with the Levita Magnetic Surgical System (MSS)

The investigators want to study the effectiveness of prophylactic cholecystectomy in patients with midgut neuroendocrine tumor (jejunum, ileum or proximal colon) who require primary tumor surgery. When patients are diagnosed and are tributary to surgical treatment, the tumor might compromise vascularization, and patients need an extensive bowel resection. The patients might also receive medical treatment with somatostatin analogs. The combination of extensive bowel resection and medical treatment might increase gallbladder stones, but patients might not develop biliary stone disease, as in the general population, where 20% of the population have gallbladder stones but only a 10 to 15 % of the population will develop symptoms. The idea comes from the lack of literature about the incidence of biliary Stone disease in patients with midgut NET tumors. It's a multicentric, open-label and randomized clinical trial to evaluate the incidence of biliary stone disease in patients with midgut NET who require primary tumor surgery combined or not to cholecystectomy. Our hypothesis suggests that patients with midgut neuroendocrine tumor who require primary tumor resection without the combination of prophylactic cholecystectomy do not have an increased incidence of biliary stone disease two years after the surgery, regardless of treatment with SSA.

The aim of this study is to evaluate the effect of TENS (Transcutaneous Electrical Nerve Stimulation) on patient outcomes after laparoscopic cholecystectomy.

Postoperative delirium is a common complication in clinical surgery. It has been reported that it can increase postoperative morbidity and mortality and lead to decreased functional and cognitive abilities. The aim of this study was to investigate the effect of ultrasound-guided bilateral rectus sheath blocks (RSB) on postoperative delirium in elderly patients undergoing laparoendoscopic single-site surgery (LESS) A double-blind, randomized controlled trial was conducted with 320 patients, aged 65-80 years, ASA I-III, who were scheduled to undergoing LESS in our hospital were selected, the patients divided into Group R and Group G by random number table method, with 160 patients in each group. Group R was subjected to a bilateral RSB under ultrasound guidance after general anesthesia, each side was given 0.5% ropivacaine 10 ml. Group G received simple general anesthesia. The mini-mental State Examination was used to assess all the patients' primary cognitive status one day before surgery. Perioperative variables were recorded to be compared. The investigators used the visual analog scale to assess patients' pain degree with postoperative, using confusion assessment method to assess whether patients experienced delirium.

this study aims to evaluate the effectiveness of the use of a basic laparoscopic instrument (Only needle holder) with a new technique for port site closure

The study will investigate the efficacy and safety of a new fascial closure device "Nasr Fascial Closure Device" compared to the Karl Storz Berci Fascial Closure Device 26173AM.

The aim of this current study is to investigate the effectiveness and safety of a novel technique which is the 5-5-5-8 where the camera port is 5 mm.

This study aims to compare the overall rate of endoscopic clearance of complicated bile duct stones by Spyglass DS peroral cholangioscopy guided holmium:YAG laser/electrohydraulic lithotripsy versus conventional BML.

In Denmark, more than 7500 cholecystectomies are performed every year. Common bile duct gallstones (CBDS) are found in 3.4% to 18% of patients undergoing cholecystectomy. A two-step approach including endoscopic retrograde cholangiography (ERC) with stone extraction and papillotomy with subsequent laparoscopic cholecystectomy has become gold standard for treatment of CBDS in Denmark. However, ERC is associated with a high risk of complications and more than 50% of patients require multiple ERCs. Recent meta analyses find that a one-step approach might be superior in terms of safety, CBDS clearance rate, hospital stay, operative time, hospital cost and stone recurrence, but much more data is needed. The preGallstep trial is an investigator-initiated multicentre randomised clinical pilot trial with blinded outcome assessment investigating a novel one-step laparoscopic cholecystectomy with common bile duct exploration and stone extraction versus conventional two-step endoscopic retrograde cholangiography with stone extraction plus a subsequent laparoscopic cholecystectomy for patients with CBDS. After enrolment, the participant will be randomised to one of the two treatment approaches. Adult patients with imaging confirmed CBDS are eligible for inclusion. Potential postoperative complications will be assessed within 90 days following the procedure. The primary outcome is the proportion of serious adverse events (corresponding to a Clavien-Dindo score II or above) requiring re-intervention within 90 days of the initial procedure. This outcome will be used for a future sample size calculation. The sample size estimate, the inclusion rate and the estimated length of subsequent trial will be used to determine the feasibility of a large pragmatic and confirmatory trial. We hypothesize that the one-step approach will significantly reduce the risk of complications and number of treatments needed thereby making a difference to hundreds of people in Denmark each year.
