Predictive factors for pancreatitis and cholecystitis in endoscopic covered metal stenting for distal malignant biliary obstruction

Abstract

Non-pancreatic cancer and contrast injection into the pancreatic duct were predictive factors for pancreatitis, and tumor involvement to the OCD was a positive predictive factor for cholecystitis after endoscopic covered SEMS placement for distal malignant biliary obstruction.

A Novel, Fully Covered Laser-Cut Nitinol Stent with Antimigration Properties for Nonresectable Distal Malignant Biliary Obstruction: A Multicenter Feasibility Study

“…Placement of SEMSs with a high AF has been reported to be significantly related to the development of pancreatitis, stent patency, and cholecystitis 16-19. We measured the AF and RF of m-CZSs using methods described previously 5.…”

A district general hospital experience of palliative biliary stenting

“…There is a subset of patients who survive much longer than this (up to 26 months). Previous work has suggested that use of contrast and a non-pancreatic cancer increase the risk of procedural complications 4. Similarly, longer term stent patency is associated with tumours <30 mm,5 or lower stage malignancy 6.…”

Overview of ERCP Complications: Prevention and Management

“…Despite these data, concern remains over potentially increased pancreatitis with use of fully covered metal stents. A small retrospective series reported that nonpancreatic cancer and injection of the pancreatic duct were risk factors for pancreatitis in patients with partially and fully covered metal stents placed [10]. The strength or osmolarity of the contrast plays no significant role in increasing the risk of pancreatitis.…”
