Soft Coagulation Using Hemostatic Forceps for Prevention of Postendoscopic Papillectomy Hemorrhage

Abstract

Aim: Few reports of the prophylactic use of soft coagulation with hemostatic forceps for postendoscopic papillectomy hemorrhage (PEPH) have been presented. The aim of this study was to clarify the utility of that procedure for prophylaxis. Materials and Methods: From April 2009 to March 2012, PEPH was treated in four patients after the development of the condition with a conventional procedure at our institution. Thereafter, from April 2012 to March 2016, soft coagulation using hemostatic forceps was performed as prophylactic hemostasis following an EP in five patients. For the latter procedure, the hemostatic forceps device (FD411‑QR, Olympus, Tokyo, Japan) was used in a closed position, with the coagulation wave set at 60 W (VIO 300D; ERBE, Tubingen, Germany). The primary outcome was the onset of PEPH, which was defined as a decrease in hemoglobin ≥2 g/dL after EP. Secondary endpoints were the success rate and the incidence of adverse events of soft coagulation using hemostatic forceps for emergency bleeding cases after EP. Results: The incidence of PEPH was 20% (1 of 5 cases) in the prophylactic procedure group, which was lower than that in the conventional procedures group (75%, 3 of 4 cases), though the difference was not statistically significant (P = 0.206, Fisher’s exact test). All cases of PEPH were successfully treated by soft coagulation using hemostatic forceps. Conclusion: Soft coagulation with hemostatic forceps may be suitable for use as a routine technique following EP to prevent PEPH.
