Active clinical trials for "Cholecystolithiasis"

Gall stone disease is one of the most common diseases occurring in the world as well as in our country, Nepal. This disease is problematic to a lot of patients and poses a huge economic burden to the country. Gall stone disease is usually diagnosed by abdominal ultrasonography as echogenic foci that cast an acoustic shadow. The risk factors for the development of gall stones are multiple; age, sex, genetic susceptibility, pregnancy, dyslipidemia, obesity, rapid weight loss, prolonged fasting and parenteral nutrition, spinal cord injury, cirrhosis, hyperbilirubinemia, and Crohn's disease. In cases of prolonged fasting, total parenteral nutrition, and spinal cord injury; biliary stasis due to lack of enteral stimulation is thought to contribute for the development of gall stones.8 Biliary stasis leads to the formation of sludge which consists of mucus, calcium bilirubinate, and cholesterol crystals. It has been established that several drugs viz.fibrates, ceftriaxone, somatostatin analogues and oral contraceptive pill can promote gall stone formation. The elective surgeries are performed after preoperative fasting >6 hrs. as recommended by different society of anesthesiology. Moreover, fasting continues throughout surgery and few post-operative hours which usually lasts more than 12 hours. Also group of people after major abdominal surgeries frequently develop post-operative hyperbilirubinemia. All these factors after any major surgeries may pose a risk for the development of Gall stones. The major goal of this study is to look if the history of major surgery in the past is one of the etiological factors for the development of gall stone disease. It is a case-control study carried out in the Department of Surgery. It will also help us analyze other multiple epidemiological factors like age, sex, BMI, drugs, lipid profile, family history lifestyle, and dietary factors associated with the disease. The epidemiological data from this study can also help us analyze other confounding and determining factors.

Cholecystectomy is recommended for patients with both gallbladder (GB) and common bile duct (CBD) stones to prevent recurrent biliary complications, unless there are specific reasons for surgery is considered inappropriate. The aim of this study was to evaluate the role of transpapillary gallbladder stent placement in surgically unfit patients with both CBD stone and gallstone.

The incidence of Gall Stones after Bariatric surgery and its association with weight loss

The aim of this study was to compare between the safety and efficacy of the harmonic shears and the commonly used clip technique in achieving safe closure and division of the cystic duct in the laparoscopic cholecystectomy in day surgery setting

Pancreaticobiliary reflux has been found in patients with cholelithiasis and gallbladder cancer associated with normal pancreaticobiliary union. However, the presence of pancreaticobiliary reflux has not been studied in patients without gallstones (healthy gallbladders). The authors believe that pancreaticobiliary reflux might be a normal phenomenon in patients with and without gallstones, although in patients with cholelithiasis it might constitute a pathological condition associated with dismotility of the biliary tree and the sphincter of Oddi.

This is an observational study of pain and outcomes from females undergoing transvaginal NOTES removal of their appendix or gallbladder. Female subjects who elect to have a transvaginal NOTES removal of their appendix or gallbladder and agree to be in this study (through signature on the informed consent form) will be followed per standard of care, with additional follow-up for data collection including the following: Subjects will complete a 7 day pain/temperature log after surgery Subjects will complete a standardized sexual function questionnaire (Female Sexual Function Index) prior to surgery and 6 months after surgery Subjects will receive a phone call at 6 months and at 1 year after surgery to capture data related to safety, adverse events, hospitalizations and patient satisfaction Additional data related to pain and outcomes will be collected at baseline/screening and at follow-up as necessary.

This is a study of new technology to allow gallbladder removal through a single small surgical incision. A surgical robot is utilized to help navigate the small space. In this study, patient characteristics are broad to assess how applicable the procedure is to everyone.

While gold standard in the treatment of symptomatic gall stones is laparoscopic cholecystectomy with instruments introduced through multiple abdominal wall incisions, transvaginal access to the peritoneal cavity offers an alternative avoiding injury of the abdominal wall. Transvaginal hybrid-NOTES cholecystectomy has been demonstrated effective and safe. However it has not been demonstrated up-to-date if intraoperative cholangiography is feasible during such procedure. This observational case series describes success and technical feasibility of intraoperative cholangiography during transvaginal cholecystectomy. The investigators hypothesis is that cholangiography is feasible equal to conventional laparoscopic cholecystectomy.

This study is a prospective, comparative, controlled, blinded study that will enroll a total of 70 adults that will undergo elective laparoendoscopic single-site incision gallbladder removal. The objective of this study is to compare Epidural versus General Anesthesia for postoperative pain, length of hospital stay, outcomes, and cost of post-cholecystectomy patients.

Virtual reality devices are widely accepted tools to familiarize surgical novices with the principles of laparoscopy. Free Virtual reality training will be tested against basic training and efficacy assessed in a randomized controlled trial of surgical novices.
