NCT ID: NCT06326281 Completed - Clinical trials for Cholecystitis/Cholelithiasis

Postoperative Pain Management in Laparoscopic Cholecystectomies

Start date: July 1, 2023
Phase: N/A
Study type: Interventional

This study is to demonstrate the effectiveness of external oblique intercostal plane block, a new block method, in the treatment of postoperative pain occurring after laparoscopic cholecystectomy operations, which are frequently and widely performed today. It aims to add new applications to multimodal analgesia methods, which provide the greatest contribution to the early recovery process after surgery, and to contribute to the early recovery process by increasing patient satisfaction.

NCT ID: NCT06311305 Recruiting - Cholelithiases Clinical Trials

Does Early Laparoscopic Cholecystectomy After ERCP Reduce the Risk of Complications

Start date: March 1, 2024
Phase: N/A
Study type: Interventional

Gallstones have been recognised since antiquity and have been found during autopsies of Egyptian mummies. Following the first successful open cholecystectomy in 1882, it was Eric Muhe, a German surgeon, who performed the first laparoscopic cholecystectomy (Lapara, the flank; and skopein, to examine) in 1985. The common mechanism of gallstone formation includes cholesterol hypersecretion, alteration in intestinal bile salt, cholesterol absorption and gall bladder hypokinesia, which leads to bile cholesterol supersaturation and nucleation. Incidence of CBD stones in cases of cholelithiasis is around 3.4%-15%.2 Choledocholithiasis can either be primary or secondary. Secondary Choledocholithiasis being more common occurs due to stones originating in gallbladder and then migrating through cystic duct to CBD. Primary bile duct stones originate from within bile ducts and are more common in Asian populations. These stones are associated with biliary stasis and bacteria.

NCT ID: NCT06287931 Recruiting - Clinical trials for Bariatric Surgery Candidate

Probiotics for Gallstones in Post-bariatric Surgery Patients

Start date: January 1, 2024
Phase: N/A
Study type: Interventional

Obesity is an increasing epidemic worldwide and has a significant impact on human health and socioeconomics. Multiple studies have shown that bariatric surgery increases the risk of postoperative gallbladder stones. Contributing factors to gallstone formation include gallbladder motility and bile supersaturation due to rapid weight loss and cholesterol mobilization. At present, the prevention and treatment of gallbladder stones in obese patients after bariatric surgery are still controversial. In recent years, the study of ursodeoxycholic acid in preventing gallbladder stone formation after bariatric surgery has become a research hotspot. At the same time, other studies have shown that taking probiotics or digestive enzymes may improve gastrointestinal symptoms and improve quality of life after bariatric surgery. Therefore, the purpose of this study was to determine the ability of probiotics to prevent gallstone formation after bariatric surgery and to evaluate the impact of oral probiotics on quality of life in patients after bariatric surgery.

NCT ID: NCT06258824 Completed - Pancreatic Cancer Clinical Trials

MicroRNAs as Bile-based Biomarkers in Pancreaticobiliary Cancers

MIRABILE
Start date: January 1, 2018
Phase:
Study type: Observational

pancreatic or biliary-tract cancer can be a serious diagnosis, as many patients present too late for surgery. Cancer cells have been found to release small messenger molecules called that regulate cancer genes called microRNAs (miRNAs). The goal of this observational study is to learn about the role of miRNAs from bile and blood samples in patients with pancreatic cancer and bile duct cancer. The main question[s] it aims to answer are: - Can this detect patients presenting with jaundice (yellow-skin) undergoing endoscopy? - Can this distinguish between the types of cancer? Participants will have blood and bile samples collected prior to diagnosis and their clinical pathway will be followed up for 6 months.

NCT ID: NCT06244589 Recruiting - Cholelithiasis Clinical Trials

Evaluation of Risk Factors Leading to Conversion From Laparoscopic Cholecystectomy to Open Surgery

Start date: February 12, 2024
Phase: N/A
Study type: Interventional

This retrospective controlled study aims to evaluate risk factors that affect open conversion in laparoscopic cholecystectomy. Patient characteristics, medical history, biochemical and radiological studies of the patient will searched from the hospital database and factors affecting open conversion will be analysed.

NCT ID: NCT06239233 Recruiting - Gallstone Disease Clinical Trials

Gallbladder Infundibulum as a Guide for Ductal Identification.

Start date: December 25, 2023
Phase:
Study type: Observational [Patient Registry]

Introduction: Bile duct injury (BDI) is a catastrophic complication of cholecystectomy, and misidentification of the cystic anatomy is considered to be the main cause. Although several techniques have been developed to prevent BDI, such as the "critical view of safety", the infundibular technique, the rates remain higher during laparoscopic cholecystectomy (LC) than during open surgery. Strategy for ductal identification during laparoscopic cholecystectomy can help to prevent laparoscopic bile duct injury. Methods: A prospective study of 196 patients who will undergo LC during the study period of one year at Nepal Mediciti Hospital will be conducted. The gallbladder infundibulum will be classified by its position located on an imaginary clock with the gallbladder neck as the center point of the dial, 3 o'clock position as cranial, 6 o'clock as dorsal, 9 o'clock as caudal, and 12 o'clock as ventral, as well as the axial position. Patient demographics, pathologic variables and infundibulum classification will be evaluated. Detailed analysis of ductal identification based on gallbladder infundibulum position will be performed in this study. All infundibulum positions will be recorded during intraoperative laparoscopic procedure.

Global Evaluation of Cholecystectomy Knowledge and Outcomes

GECKO
Start date: July 31, 2023
Phase:
Study type: Observational

Cholecystectomy is amongst the most common surgical operations performed worldwide. Surgical candidates are treated for biliary pathologies, such as biliary colic, cholecystitis and gallstone pancreatitis. In patients who are deemed fit for surgery, cholecystectomy can be performed under three main settings: (1) emergency setting at index admission; (2) elective setting with no previous admissions; or (3) delayed setting with one or more previous gallbladder-related admissions. The advent of laparoscopy fundamentally evolved biliary surgery and quickly became the "gold standard" approach. Recent multicentre collaborative studies have elucidated that the burden imposed on healthcare systems by laparoscopic cholecystectomies is primarily due to patient readmissions and complications arising from the operation, rather than perioperative mortality burden that was more commonly seen in open surgery. As a result, national and international societies have shifted their focus towards creating a culture of safety around this procedure, with the overarching goal of improving patient satisfaction and reducing hospital costs. The universal establishment of safe cholecystectomy is a complex process that relies not only on the operation itself, but also on various other factors such as promoting adequate training, improving hospital infrastructure, and enhancing perioperative patient care. There remains a paucity of evidence around the variations of safe provision of laparoscopic surgery for gallbladder disease internationally, including low- and middle-income countries. To bridge this knowledge gap, the Global Evaluation of Cholecystectomy Knowledge and Outcomes (GECKO) study (GlobalSurg 4) will be an international collaborative effort, delivered by the GlobalSurg network, that will allow contemporaneous data collection on the quality of cholecystectomies using measures covering infrastructure, care processes and outcomes. It will be disseminated via contacts from the National Institute for Health and Care Research (NIHR) Global Surgery unit, leading emergency general surgeons and specialist organisations.

EULAT Eradicate GBC

EULAT
Start date: December 1, 2019
Phase:
Study type: Observational

Gallstones are relatively frequent in women and constitute one of the main risk factors for gallbladder cancer (GBC). Currently, GBC diagnosis is mainly based on imaging (ultrasound or abdominal CT) associated with invasive examinations (biopsy and surgery), with no marker available to date to accurately predict risk and diagnose the disease early. The only curative treatment for GBC remains surgery with complete resection of tumors in early stages. Given the aggressiveness of GBC and the very limited therapeutic options, as well as the possibility of preventing GBC by cholecystectomy during the 10 to 20 years required for the development of gallbladder tumors, it is imperative to develop effective and efficient prevention strategies based on a prioritization of interventions according to environmental and genetic-molecular risk factors. We aim to identify epidemiological factors linked to the development of GBC, and to identify, validate and functionally characterize genetic-molecular markers in blood, saliva, urine, bile and stool that allow risk prediction, early diagnosis and precision treatment of incidental tumors.

Flare Type Self-expandable Metal Stents (SEMS) vs Plastic Stent for the Treatment of Difficult Common Bile Duct Stone

TEMASTI
Start date: March 2024
Phase: N/A
Study type: Interventional

Migration of stones from the gallbladder to the common bile duct (CBD) facilitated by gallbladder contractions can be listed as a complication of gallstones disease. In the case of common bile duct stone (CBDs) migration, an endoscopic cholangiopancreatography (ERCP) should be offered for both symptomatic and asymptomatic patients fit for the procedure. An ERCP with an adequate endoscopic sphincterotomy obtains a complete biliary clearance in about 80-90% of the patients[5]. Whilst most cases are successfully treated with such first-line approaches, about 10-15% need alternative and/or adjunctive techniques to achieve bile duct clearance. These conditions are generally defined as "difficult" bile duct stones, a broad category of cases that encompasses very different scenarios. In the case of irretrievable CBDs, the European Society of Gastrointestinal Endoscopy (ESGE) recommends the endoscopic placement of a temporary biliary plastic stent to warrant biliary drainage. Since their introduction, fully covered self-expanding metal stents (FCSEMS) have rapidly been adopted for the treatment of benign biliary conditions such as strictures, leaks, or bleeding. In a recent retrospective study it has been shown that FCSEMS are useful in the approach of difficult lithiasis of CBD with no significant adverse events associated. Moreover, a promising FC-SEMS with a particular prosthesis design (flare type - Niti-S "S-Type" Taewoong) could be even more useful since it reduces the frequent complication of fully covered stents which is the migration of the prosthesis. However, prospective data on the effectiveness and on the adverse events rate on the use of SEMS for incomplete stone CBDs clearance are still lacking. Therefore, the investigators aim to estimate the incidence of adverse events, complete biliary clearance, and migration rate after 3-6 month from ERCP index (stent positioning), comparing plastic stents vs FC-SEMS (Niti-S "flare type" - Taewoong).

NCT ID: NCT06130163 Completed - Clinical trials for Cholelithiasis, Common Bile Duct

Intraoperative ERCP Versus Therapeutic Splitting in Cholecysto-, Choledocholithiasis

Start date: January 1, 2020
Phase:
Study type: Observational

At our hospital (Kepler University Hospital Linz) we perform all variants of ERCP (preoperative, intraoperative, postoperative ERCP). In cases of simultaneous cholecysto- and choledocholithiasis. Hardly any other hospital in Austria prefers intraoperative ERCP or offers it at all. We have established a standardized procedure with implemented logistics. We want to compare intraoperative and postoperative ERCP.
