Active clinical trials for "Gallstones"

In the current era, laparoscopic cholecystectomy is the treatment of choice for symptomatic gallstone disease. The aim of this study is to find out the prevalence of open cholecystectomy among patients undergoing laparoscopic cholecystectomy in a tertiary care center.

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.

Risk factor of cholelithiasis is rapid weight loss after bariatric surgery and change in the gallbladder function which is secondary to surgery. Many observational studies support this fact, and a high incidence of 28% -71% after gastric bypass surgery (RYGB) was reported in them. According to another publication, the incidence of gallbladder diseases is 5-36% after jejunoileal bypass surgery and 2.8-36% after gastric bypass surgery.

Observative and descriptive study of 10 patients, which were diagnosed with a Cholecystoduodenal fistula, All electronic medical records were retrospectively reviewed.

Single-incision laparoscopic cholecystectomy (SILC) requires a larger incision than standard laparoscopy, which may increase the incidence of incisional hernias. This study evaluated SILC and standard multiport cholecystectomy with respect to perioperative outcomes, hospital stay, cosmetic results, and postoperative complications, including the 5-years incisional hernia rate.

This research proposal is a pilot double-blind randomized control trial evaluating the impact on diagnostic accuracy of a Clinical UltraSound (CUS) teaching for gallbladder assessment using exclusively healthy volunteers for practical sessions. Classically, a number of 25 to 50 CUS of the gallbladder is reported to achieve competency. Many CUS curricula or guidelines recommend reporting pathological cases, either a certain amount, either generically, in their core-ultrasound competency requirements. Using healthy volunteers is rarely meant to verify the hypothesis that practical sessions based on exclusively normal patterns combined with presentation of pathological ultrasound loops or images during theoretical sessions, could further allow reaching diagnostic accuracy requirements in clinical practice. In the present study, participants will be medical students in their 5th year, naïve to CUS use. Participants will be randomly be distributed between a control group undergoing a standard practical teaching on models presenting uncomplicated gallstones or normal gallbladder (no gallstones), and an intervention group undergoing a practical teaching exclusively on models presenting a normal gallbladder. Participants will be "blinded" to study endpoints as well as to group allocation. After three days of practical teaching on day 0-10-30, students will be evaluated on day 60 by 2 external investigators blinded to students group allocation. Diagnostic accuracy for gallstones will be measured using sensitivity and specificity. Statistical analysis will be performed blinded to students' name using IBM SPSS statistics 26.0 (SPSS Inc., Chicago, IL, USA). As is classical, the statistical tests will be rejected whenever the observed p-value is smaller than 0.05. Corrections for multiple testing will be used. A comparable diagnostic accuracy between groups could further support the use of healthy volunteers during practical teaching and ease clinical ultrasound curricula. Such a finding wouldn't however carry away the need for enhancing competencies during clinical practice or the need for continuing medical education, as for any medical procedure.

Mirizzi syndrome is an infrequent complication of long-standing cholelithiasis. Extrinsic compression of the common hepatic duct is usually caused by an impacted stone in Hartmann's pouch or cystic duct resulting in the development of cholecystobiliary fistula. This syndrome is classified based on the presence and severity of cholecystobiliary fistula. Mirizzi syndrome is challenging to diagnose preoperatively and may require complex biliary surgical procedures for resolution. Endoscopic treatment is a safe alternative with a high success rate. Single-operator cholangioscopy combined with lithotripsy has been shown to have a 90-100% success rate in the treatment of biliary stones. Herein, A single center experience treating Mirizzi syndrome with single-operator cholangioscopy guided electrohydraulic lithotripsy is presented. Difficult management of Mirizzi syndrome has led to research of new treatment options to minimize the risk of high rate complications. Single-operator cholangioscopy in combination with laser lithotripsy is an adequate and safe alternative for the treatment of this condition.

Patients with complex biliary stone disease are challenging to treat. The investigator present their experience in using urological interventions to treat challenging biliary stones. Methods: Fifteen patients with biliary calculi underwent 21 interventions using either extracorporeal shock wave lithotripsy (ESWL), percutaneous transhepatic choledochoscopy, percutaneous transcystic choledochoscopy, or a combination of these.

The goal of this observational study is to assess the size and location of cutaneous sensory block area after dual laparoscopic assisted transverse abdominis plane block (L-TAP) with ropivacaine in patients undergoing laparoscopic cholecystectomy. L-TAP is applied as a medial subcostal infiltration between midclavicular and central sternal lines and a lateral subcostal infiltration between midclavicular and anterior axillary line bilaterally.
