NCT ID: NCT02554097 Active, not recruiting - Cholelithiasis Clinical Trials

Chinese Registry Study on Treatment of Cholecysto-Choledocholithiasis

CREST Choles
Start date: August 2015
Phase:
Study type: Observational [Patient Registry]

Patients with gallstone and confirmed common bile duct stones are registered in this study. The three managements for common bile duct stones are endoscopic sphincterotomy (EST), laparoscopic common bile duct exploration (LCBDE) and laparoscopic transcystic common bile duct exploration (LTCBDE). Patients will be assessed at baseline, preoperative investigations, operative method, operative time, conversion to open procedure, intraoperative and postoperative complications, and the presence of retained and recurrent stones. All patients were followed up for 3 years by telephone interview ang outpatient visits. Abdominal US and liver function tests were carried out whenever any abdominal symptom appeared during the follow-up period. If there were unusual findings, magnetic resonance cholangiopancreatography(MRCP) was carried out.

NCT ID: NCT02472509 Terminated - Gallstones Clinical Trials

The Role of Ursodeoxycholic Acid in Treatment of Gallstones in Hemolytic Disorders

Start date: December 2014
Phase: Phase 4
Study type: Interventional

It is well established that hemolytic diseases predispose patients to the development of pigment gallstones. Gallstones are noted in at least 5% of children under the age of 10 years, increasing to 40-50% in the second to fifth decades. The co-inheritance of Gilbert's syndrome increases the risk of cholelithiasis four to five-fold. In patients with chronic hemolysis, total bile lipid concentration is decreased and the total bilirubin to total lipid ratio is increased. This suggests that the conjugating capacity of hepatocytes is surpassed by the excessive amount of bilirubin resulting from hemolysis. Increased bilirubin monoconjugate and unconjugated bilirubin can precipitate in bile and form complexes with inorganic ions, mostly calcium, and develop into stones. Patients with hemolytic disorders can also develop biliary sludge, a suspension of precipitated particulate matter in bile dispersed in a viscous, mucin-rich liquid phase . The chemical composition of the precipitates correlates well with the composition of the associated stone and sludge often stands as a harbinger of future stone development. There is strong data suggesting a benefit in treating cholelithiasis with UDCA and also in preventing gallstone development in various high risk scenarios. There are several proposed mechanisms for the positive effect of UDCA in primary prevention of pigment stones. Mucoglycoproteins are present in significant amounts in black pigment stones and contribute to the matrix of gallstones. UDCA suppresses the secretion of protein and decreases the levels of various proteins in bile . It has also been suggested that increased colonic bile salt may solubilize unconjugated bilirubin and may prevent calcium complexing. There is no published data at present on the role of UDCA in prevention and treatment of cholelithiasis in hemolytic diseases. The investigators hypothesise that UDCA can be of benefit to patients with hemolytic disorders in the primary prevention of pigment stones, possible resolution of biliary sludge and existent stones, and reduction of symptomatic episodes of cholelithiasis.

NCT ID: NCT02469935 Completed - Gallstones Clinical Trials

Accuracy of Surgeon-performed Ultrasound in Detecting Gallstones - a Validation Study

Start date: October 2011
Phase: N/A
Study type: Observational

Aims: To prospectively investigate the accuracy of surgeon-performed ultrasound for the detection of gallstones. Methods: 179 adult patients, with an acute or elective referral for an abdominal ultrasound examination, were examined with a right upper quadrant ultrasound scan by a radiologist as well as surgeon. The surgeons had undergone a four-week long education in ultrasound before participating in the study. Ultrasound findings of the surgeon were compared to those of the radiologist, using radiologist-performed ultrasound as reference standard.

NCT ID: NCT02461147 Completed - Cholecystitis Clinical Trials

Prospective Validation of "Cholecystectomy First" Strategy for Gallstone Migration

Start date: September 2013
Phase:
Study type: Observational

Initial cholecystectomy with intraoperative cholangiogram, followed if required by ERCP, has been implemented at the investigators institution as the standard management strategy for patients at intermediate risk of common bile duct stone migration, following a randomized controlled trial previously published by the same investigators team. The aim of this study is to prospectively analyze the outcomes of this strategy.

NCT ID: NCT02396927 Recruiting - Cholelithiasis Clinical Trials

3D HD Versus 2D HD in Cholecystectomy

Start date: March 2015
Phase: N/A
Study type: Interventional

The aim of this study is to compare 3D-laparoscopy versus 2D-laparoscopy with the use of HD resolution in cholecystectomy in terms of error rating, performance time and subjective assessment.

NCT ID: NCT02375529 Completed - Cholelithiasis Clinical Trials

A Trial of Single Incision Versus Four Ports Laparoscopic Cholecystectomy

Start date: May 2011
Phase: N/A
Study type: Interventional

Background: Single-incision laparoscopic cholecystectomy (SILC) is increasingly being used as a minimally invasive surgery with potential benefits over 4-port laparoscopic cholecystectomy (LC) in terms of postoperative pain and faster recovery. Methods: Seventy-three patients with symptomatic cholelithiasis were randomized to SILC (n=37) or LC (n=36). Data measures included operative details, adverse events, postoperative pain and analgesic requirements, success of the ambulatory process, return to normal activity and return to work, cosmetic results and quality of life score.

NCT ID: NCT02363699 Completed - Cholelithiasis Clinical Trials

Endovenous Lidocaine and Serum Cytokines Concentration

Start date: July 2013
Phase: Phase 4
Study type: Interventional

Ineffective treatment of postoperative pain may cause organic damage and chronic pain. Nevertheless, opioids, the leading drugs used for this purpose, present side effects that sometimes restrict their usability. In a multimodal context, new postoperative analgesia techniques have been developed focusing in the reduction of opioid use and their adverse effects, as well as postoperative chronic pain prevention. In this background, continuous intravenous infusion of lidocaine during perioperative period has shown to be promising. This trial aimed to compare postoperative analgesia, opioid consumption, duration of ileus and length of hospital stay and IL-1, IL-6, IL-10, α TNF and γ IFN levels in patients undergoing to laparoscopic cholecystectomies who received intravenous lidocaine in comparison to a control group. Intravenous lidocaine in the perioperative period of laparoscopic cholecystectomies was not able to reduce postoperative pain, opioid consumption, and duration of ileus or length of hospital stay. However, its anti-inflammatory effect was evidenced by the significant changes in the studied cytokines.

NCT ID: NCT02357589 Completed - Cholecystolithiasis Clinical Trials

3D vs 2D HD Laparoscopy in Cholecystectomy

Start date: January 2015
Phase: N/A
Study type: Interventional

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).

NCT ID: NCT02351492 Completed - Gallstone Disease Clinical Trials

Radiological Investigation of Bile Duct Obstruction

RIBO
Start date: May 2015
Phase: N/A
Study type: Interventional

Patients with gallstone disease should be checked whether a common bile duct (CBD) stone could be present. In case of a certain suspicion for CBD stones further investigations should be performed. This can either be done by magnetic resonance cholangio-pancreaticography (MRCP) or by intraoperative cholangiography. The study investigates which pathway would be favorable in regard of an early hospital demission.
