Can prophylactic argon plasma coagulation reduce delayed post-papillectomy bleeding? A prospective multicenter trial.

Area of Science:

• Gastroenterology
• Endoscopic Surgery
• Oncology

Background:

• Delayed bleeding post-papillectomy is a significant clinical concern.
• Current strategies lack consensus for minimizing delayed bleeding.
• Residual tumor persistence also poses a challenge after endoscopic papillectomy.

Purpose of the Study:

• To evaluate the efficacy of prophylactic argon plasma coagulation (APC) in reducing delayed bleeding after endoscopic papillectomy.
• To assess the impact of prophylactic APC on residual tumor rates post-papillectomy.

Main Methods:

• A prospective pilot study involving patients with benign ampullary tumors.
• Patients received either conventional snaring papillectomy with prophylactic APC or conventional papillectomy alone.
• Follow-up duodenoscopy and 12-month monitoring assessed bleeding and tumor persistence.

Main Results:

• Delayed bleeding rates were 30.8% in the APC group versus 21.4% in the non-APC group (P=0.434).
• Tumor persistence rates did not differ significantly between groups at multiple follow-up points.
• Post-procedure pancreatitis rates were comparable between the groups (23.1% vs 35.7%, P=0.310).

Conclusions:

• Prophylactic APC does not appear effective in decreasing delayed post-papillectomy bleeding.
• The study suggests APC is not beneficial for remnant tumor ablation immediately after conventional papillectomy.
• Further research may be needed to explore alternative methods for managing post-papillectomy complications.
