Active clinical trials for "Gallstones"

Pain following laparoscopic cholecystectomy (LC) results in morbidity and is a barrier to same day discharge. In several trials local anaesthetic (LA) washed over the liver and gall bladder decreases pain. In many patients pain has a strong component attributable to diaphragmatic origin. A wash of LA over the liver and gall bladder is unlikely to provide high levels of analgesia to pain fibres from the diaphragm. The investigators hypothesise that LA injected to the right hemidiaphragm during LC would be more effective than wash. Methods Double blind randomised controlled trial of 128 consecutive subjects undergoing elective LC. Control -sham injection of diaphragm and sham wash over liver/GB with saline; Test treatment 'subperitoneal LA' - bupivocaine injection/sham wash; Internal control 'topical LA' - sham injection/bupivocaine wash. Primary outcome: pain scores in theatre recovery and the ward. Secondary outcomes: analgesic use, physiological observations, time to eating and mobilising, day case surgery.

The purpose of this study is to determine the safety and efficacy of the Endograb system which is an internal laparoscopic retractor device. This retractor device is inserted into the abdominal cavity through one of the 5 mm trocars and obviates the need for a separate dedicated trocar for retraction. Therefore enables the reduction of the number of abdominal incisions in a laparoscopic operation.

The study is designed to assess whether repeated dosing with CE-326,597 will cause patients with asymptomatic gallstones (as detected on screening abdominal ultrasound) to become symptomatic. In addition, the study will characterize the pharmacokinetics of CE-326,597.

We conduct a randomized, double-blind, placebo-controlled trial on effects of UDCA on biliary pain and complications in highly symptomatic gallstone patients scheduled for cholecystectomy. We also evaluate potential beneficial effects of impaired gallbladder motility

The objective of the trial was to explore the effect of different infusion volume on perioperative bladder and blood volume in patients undergoing daytime surgery assisted by bladder and vascular ultrasound and transthoracic echocardiography.

This is a prospective, multi-center, randomized, single-blind, parallel-controlled clinical trial to evaluate the safety and efficacy of the Chinese domestic endoscopic instrument control system in clinical treatment.

To investigate feasibility and safety of intraoperative bile duct clearance by sphincter of Oddi balloon dilatation via cystic duct at cholecystectomy. Primary endpoint: rate of successful bile duct stone clearance (feasibility). Secondary endpoints (safety): rate of peri-interventional complications (injury to the common bile duct, bleeding, injury to surrounding organs: stomach, duodenum, liver) and short-term postoperative complications (bile leak, cholangitis, lipasaemia, pancreatitis, pneumonia). Duration of procedure. Length of hospital stay.

It is designed to monitor the efficacy of nasal cannula or hıgh-flow nasal oxygen in geriatric patients for endoscopıc retrograde cholangıopancreatography procedures. The aim of the study is to evaluate the efficacy and safety of oxygen support obtained with low-flow nasal cannula and hıgh-flow nasal oxygen during endoscopıc retrograde cholangıopancreatography in the patient group at risk for adverse respiratory events. We hypothesized that high-flow nasal oxygen administration can prevent adverse respiratory events such as deep sedation and patient position that may endanger the airway safety of patients, and reduce the problems in cardiac and hemodynamic parameters that may develop.

Endoscopic bile duct stone (BDS) removal is a well-established treatment; however, the preference for basket or balloon catheters for extraction is operator-dependent It is reported that complete endoscopic treatment with a single catheter is more likely when choosing a balloon catheter over a basket catheter for extraction of BDSs≤10mm. However, a study comparing the two catheter types in patients with periampullary diverticulum has not been performed, and there is no strong basis on which to recommend the balloon catheter as a first-line stone removal device. The investigators therefore conducted a multicenter prospective randomized trial to compare catheter performance in patients with periampullary diverticulum.

Many feasibility studies have been published on Single Port surgery, but no comparative studies have shown any advantages compared to standard laparoscopy. The purpose of this study is to compare the clinical outcomes and economical issues of laparoscopic cholecystectomies using single port transumbilical approach and three trocars.
