Active clinical trials for "Gallstones"

Surgical removal of the gallbladder is needed in 1 million people per year in the USA. The procedure is done by placing four tubes (cannula) from 5 to 10 mm through the abdominal wall. Air is placed in the abdominal cavity and a lighted scope is placed through one cannula. The space in the abdominal cavity can then be seen on a video screen. Thin retractors and dissecting instruments are placed through the other cannula and the gallbladder is removed using the video screen for vision. The gallbladder duct and the artery are usually occluded with clips or stitches. In this study we propose to do the procedure though a single 5 mm incision placed at the umbilicus and a second access through the vagina using a flexible endoscope. The gallbladder will be retracted using strings (sutures) attached to the gallbladder. The dissection will be done using laparoscopic instruments (scissors, knives, dissectors) placed through the laparoscopic port. A flexible grasper may be used in the endoscope to help with retraction. An endoscopic snare or grasper will be used to grasp the gallbladder and remove it from the abdomen through the vagina. This study evaluates the ability to do laparoscopic cholecystectomy with one skin incision and one vaginal incision. This will provide the basis for future studies evaluating decreased pain and costs with transvaginal assisted cholecystectomy.

Pneumoperitoneum is formed with CO2 during laparoscopic abdominal operations. Effect of pneumoperitoneum on coagulation factors is not well known. In our study the investigators aimed to compare the general anesthesia(GA) and combined spinal-epidural anesthesia (CA) during laparoscopic cholecystectomy(LC) with effect on coagulation factors. Fifty patients will be randomly assigned to either the Laparoscopic cholecystectomy under Combined anaesthesia (25 patients) or Laparoscopic cholecystectomy under general anaesthesia (25 patients). All patients has symptomatic gall stone disease or polyp of gall bladder.

Collection of PROMs (Patient Reported Outcome Measures) data from patients before and after an operation to remove their gallbladder for the treatment of symptomatic gallstones. This PROMs data will provide information to clinicians and trusts about the health gain following this type of surgery and the impact on patient's quality of life. This information will be collected by the implementation of the patient Website aboutmyop.org. This will not only allow patients to complete quality of life (PROMs) questionnaires online, but will also allow them to access information on their condition and necessary surgery, in addition to post-operative follow-up.

Achievement of critical view of safety (CVS) is recommended to reduce risk of hilar injury in laparoscopic cholecystectomy. Indocyanine green (ICG) fluorescence cholangiography, a novel technique of real time biliary visualization, is postulated to assist dissection during laparoscopic cholecystectomy (LC). However, its use in providing a faster and safer LC has yet to be established. The main objective of this study is to evaluate whether the use of ICG enhanced fluorescence cholangiography will help in earlier identification critical view of safety during LC.

A single-blinded, prospective randomized parallel controlled clinical trial was designed and conducted from December 2019 to November 2020. 82 patients with a gallstone, gallbladder polyp and other benign gallbladder diseases were enrolled in this study. Finally, 82 patients were randomly divided into the Micro Hand S surgical robot group and the da Vinci surgical robot group. Standard robot-assisted transabdominal cholecystectomy was conducted using the Micro Hand S robot or the da Vinci robot. The success rate of operation, assembly time, operation time, intraoperative hemorrhage, time to first flatus, postoperative pain, comprehensive complication index, resident time and patient satisfaciton were recorded. The aim of the study is to determine whether the newly developed Chinese Micro Hand S surgical robot results in non-inferiority outcomes in cholecystectomy compared with the prevalent da Vinci robot.

Investigators conducted a randomised perspective study to determine whether the use of HFJV instead of conventional mechanical ventilation will reduce the adverse cardiovascular effects of pneumoperitoneum during laparoscopic surgery.

By binding to the nuclear receptor FXR, bile acids not only regulate their own turn-over but presumably also pivotal steps in cholesterol, triglyceride and glucose metabolism as shown in laboratory animals. Obeticholic acid (OCA) is a semisynthetic bile acid with very high affinity to FXR. In a pharmacodynamic study the effects of OCA on bile acid, lipid and glucose turn-over are studied in 20 morbidly obese and 20 gallstones patents, respectively, that are administered OCA at 25 mg/day in three weeks before bariatric (BS) or gallstone (GS) surgery where in addition to blood samples also biopsies are taken from the liver and in the case of BS, omental and subcutaneous adipose tissue and in case of GS, gallbladder bile.

Surgery induced sterile inflammation leaves behind a biomolecular footprint measurable by various pro-inflammatory markers e.g. IL-6, CD(Cluster of differentiation)19B, HsCRP(High-sensitivity CRP) etc. Music is a non-pharmacological means in attenuating this inflammatory pathway thereby improving Health related quality of life measurable by improved postoperative convalescence. Correct timing of music application is a lacuna in the knowledge. This research aims at evaluating the effect of preoperative music on sterile inflammation induced by index Laparoscopic Surgery (Laparoscopic Cholecystectomy) and its proposed beneficial effects on patient reported outcomes. A total of 50 patients divided into 2 groups (test and control) will be evaluated in this triple blind randomized controlled study aiming at evaluating the biomolecular signatures of sterile inflammatory response and its correlation with improved postoperative convalescence. All the patients will be followed up for a period of 1 month postoperatively to assess for overall improvement in health related quality of life. Collected data will be analysed using updated SPSS software and a p value of less than 0.05 will be taken as statistically significant in support of the measured indices.

The purpose of this study is to determine whether the magnetic compressive anastomosis has a better outcomes than traditional manual anastomosis on superior bilioenteric anastomosis.

The objective of this clinical trial is to visualize the bile ducts by injecting a contrast that is only visible with infrared light. For this, we administrate an intravenous low dose of ICG before a cholecystectomy. During the intervention the tissue will be exposed to infrared light to visualize the bile ducts. This technique aims to increase safety in surgery to avoid damaging bile or vascular structures during gallbladder interventions.
