BACKGROUND: Although pancreatic stenting is recommended for the prevention of postprocedure pancreatitis during endoscopic papillectomy (EP), in some patients it is technically difficult to perform postprocedure insertion of a pancreatic stent after endoscopic resection.
GOALS: This study assessed the feasibility of a novel EP for the purpose of reliable post-EP pancreatic stenting.
STUDY: We conducted a prospective pilot study involving 10 consecutive patients with tumor of the major duodenal papilla. We developed a novel pancreatic stent, which is attached to a suture, and devised a method by which the stent is first placed at an upstream migration into the major pancreatic duct above the orifice before resection and then placed at an appropriate location after endoscopic resection by pulling the suture attached to the stent [inside pancreatic stenting papillectomy (IPSP)].
RESULTS: The pancreatic stent was successfully placed at an upstream migration into the pancreatic duct above the orifice in 9 of the 10 patients. For the 9 patients with successful pancreatic stent placement, IPSP was performed. Although the suture was cut in 1 patient, pancreatic stents could be placed appropriately across the orifice by pulling the suture in all patients. Although bleeding occurred in 3 patients, there was no pos-procedure pancreatitis.
CONCLUSIONS: IPSP is a practicable method allowing reliable post-EP pancreatic stenting and can contribute to pancreatitis prevention. However, larger studies need to be performed before its use can be recommended.
