A clinical, controlled, prospective, longitudinal, descriptive, observational and double-blinded study was designed. Patients of any gender between 15 and 70 years, with a diagnosis of choledocholithiasis, and who required a cholecystectomy with an exploration of bile ducts were included. Conventional cholecystectomy was performed and perioperative T-tube CBD pressure was registered immediately after the procedure, and weekly thereafter, with a 6-week follow-up.~Control T-tube cholangiogram was performed at six weeks to exclude residual stones. Data was analyzed with T-test for parametric values.
A study that included patients of any gender between 15 and 70 years, with the diagnosis of choledocholithiasis who required a cholecystectomy with an exploration of bile ducts. Conventional cholecystectomy was performed and a T-tube was inserted in the common bile duct (CBD) to measure the intraluminal pressure immediately after the procedure, and weekly thereafter, with a 6-week follow-up. A control T-tube radiological study was performed at six weeks to exclude residual stones.
