Filter by:The Percutaneous Cholangiopancreatoscopy (PCPS) registry is an observational, multicentric, prospective, and retrospective registry of patients undergoing the percutaneous cholangiopancreatoscopy procedure at sites across the United States. In the retrospective component of the study, clinical and procedural data regarding patients who have undergone clinical indicated percutaneous cholangiopancreatoscopy procedure in the past will be collected from all the registry sites and stored in a secure database. The prospective component of the registry will run for three years at each site where patients undergoing the clinically indicated percutaneous cholangiopancreatoscopy procedure will be enrolled in the study, and the patients' data will be collected whenever the patients present to interventional radiology (IR) for a procedure or clinic visit.
The investigators want to study the effectiveness of prophylactic cholecystectomy in patients with midgut neuroendocrine tumor (jejunum, ileum or proximal colon) who require primary tumor surgery. When patients are diagnosed and are tributary to surgical treatment, the tumor might compromise vascularization, and patients need an extensive bowel resection. The patients might also receive medical treatment with somatostatin analogs. The combination of extensive bowel resection and medical treatment might increase gallbladder stones, but patients might not develop biliary stone disease, as in the general population, where 20% of the population have gallbladder stones but only a 10 to 15 % of the population will develop symptoms. The idea comes from the lack of literature about the incidence of biliary Stone disease in patients with midgut NET tumors. It's a multicentric, open-label and randomized clinical trial to evaluate the incidence of biliary stone disease in patients with midgut NET who require primary tumor surgery combined or not to cholecystectomy. Our hypothesis suggests that patients with midgut neuroendocrine tumor who require primary tumor resection without the combination of prophylactic cholecystectomy do not have an increased incidence of biliary stone disease two years after the surgery, regardless of treatment with SSA.
This study aims to compare the overall rate of endoscopic clearance of complicated bile duct stones by Spyglass DS peroral cholangioscopy guided holmium:YAG laser/electrohydraulic lithotripsy versus conventional BML.
