- Abstract
- Background and Aim:A major concern about endoscopic snare papillectomy (ESP) is the risk of procedure-related pancreatitis. To maintain pancreatic duct access for stent placement after ESP, wire-guided ESP (WP) was introduced. The aim of the study was to compare post-procedure pancreatitis rates, the success rate of pancreatic stent insertion, and complete resection rates between WP and conventional ESP (CP) procedures.
Methods:This was a multi-center, prospective, randomized pilot study. Forty-five patients with ampullary tumors were randomly assigned to a WP group (n=22) or a CP group (n=23). In the WP group, a guidewire was placed in the pancreatic duct prior to ESP. A 5-Fr pancreatic stent was passed over the guidewire and placed across the pancreatic duct orifice.
Results:Complete resection was achieved in 20 patients (91%) in the WP group and 18 patients (78%) in the CP group (P=0.414). A pancreatic stent was placed successfully in all patients in the WP group but in only 15 patients (65%) in the CP group (P=0.004). Post-papillectomy pancreatitis occurred in four (18%) patients in the WP and three (13%) patients in the CP groups (P=0.960). In the CP group, three of eight (37.5%) patients without stents developed pancreatitis compared with zero of 15 patients with stents (P=0.032).
Conclusions:The WP method is a useful technique used to insert a pancreatic stent after ESP, compared with CP. However, there was no significant difference in the post-procedure pancreatitis or complete resection rates between the two methods.
