The goal of this longitudinal observational cohort study is to examine the changes in the composition and diversity of gut microbiome and systemic metabolome in patients with symptomatic gallbladder stones with or without concomitant common bile duct (CBD) stones who will be undergoing cholecystectomy with or without prior endoscopic sphincterotomy (ERCP-ES) and CBD stones extraction. The main questions it aims to answer are whether there are: * differences in gut microbiome diversity and composition before and after cholecystectomy * differences in systemic metabolome before and after cholecystectomy * gut microbiome and systemic metabolome changes after cholecystectomy Participants will be asked to provide stool, urine, plasma and saliva samples prior to and 1-6 months after cholecystectomy. For patients with concomitant CBD stones who undergo ERCP-ES before cholecystectomy, bile specimens will be collected from the bile duct during ERCP-ES as well as the gallbladder and/or during cholecystectomy.

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.

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.

Collection of PROMs (Patient Reported Outcome Measures) data from patients before and after an operation to remove their gallbladder for the treatment of symptomatic gallstones. This PROMs data will provide information to clinicians and trusts about the health gain following this type of surgery and the impact on patient's quality of life. This information will be collected by the implementation of the patient Website aboutmyop.org. This will not only allow patients to complete quality of life (PROMs) questionnaires online, but will also allow them to access information on their condition and necessary surgery, in addition to post-operative follow-up.

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.

Laparoscopic Cholecystectomy (LC) is the treatment of choice for symptomatic gallstone disease. Single-port access cholecystectomy (SL) has been recently introduced using only one, trans-umbilical placed port. The method has been denominated as ''scarless.'' However, it is unknown whether SL significantly improves body and cosmesis images as well as the quality of life (QoL), reported directly by the patients. Furthermore SL promises to reduce postoperative pain and to be cost-effective due a faster postoperative recovery. The aim of this Double Blind Randomized Controlled Trial (RCT) is to demonstrate whether SL is superior to LC in improving patients', body and cosmesis images as well as QoL and to analyse cost-efficiency. Based on the sample size calculations, a total of 110 patients will be randomised to either LC or SL. The primary endpoint will be the cosmetic score. Costs, pain, time to convalescence, quality of life and complications and will also be compared as secondary endpoints. This study will provide evidence-based patient-oriented information regarding the SL procedure and its further use.
