Endoscopic papillectomy is widely performed as a less invasive procedure for ampullary
tumors compared with surgery [1]
[2]; however, it occasionally causes refractory bleeding. Endoscopic hemostasis with
clipping or electrocoagulation is used for pulsatile bleeding [3]; however, there is a risk of perforation at the post-endoscopic papillectomy ulcer.
Under these conditions, electrocoagulation using bipolar hemostatic forceps (Hemostat
Y; Pentax, Tokyo, Japan) effectively minimizes the risk of excessive tissue injury
[4]
[5]. Herein, we report two cases of endoscopic papillectomy-related bleeding that were
successfully treated using bipolar forceps ([Video 1]).
Use of bipolar hemostatic forceps was effective for pulsatile bleeding while preventing
tissue injury to post-endoscopic papillectomy ulcers.Video 1
Case 1: A 61-year-old woman with an ampullary tumor underwent an endoscopic papillectomy.
Pulsatile bleeding was observed at the center of the ulcer immediately after en bloc
resection with a snare. First, prophylactic clipping was performed on the anal side.
Subsequently, the bleeding point was grasped and coagulated by using the bipolar hemostatic
forceps. No further bleeding was observed after flushing with saline solution ([Fig. 1]). Additional clipping was performed to prevent rebleeding. Pancreatic and biliary
stents were placed, and self-assembling peptide was sprayed ([Fig. 2]). The patient was discharged on the seventh day after the endoscopic papillectomy,
without any complications.

forceps. d No further bleeding was observed.

Case 2: A 51-year-old woman with an ampullary tumor underwent endoscopic papillectomy
([Fig. 3]). The following day, she experienced hematemesis, and emergency endoscopy was performed.
The post-endoscopic papillectomy ulcer was covered with clots and fresh blood. Pulsatile
bleeding was detected around the pancreatic stent after clot removal and flushing
with saline solution. The bipolar hemostatic forceps was used to accurately grasp
the bleeding point. Endoscopic hemostasis was successfully achieved after two instances
of bipolar coagulation. No further bleeding was observed, and the patient was discharged
as scheduled ([Fig. 4]).
Fig. 3 Case 2. Endoscopic papillectomy. a Oozing was observed during the procedure. b The bleeding spontaneously ceased, and prophylactic clipping was performed.
Fig. 4 Case 2. Emergency endoscopy on the following day. a The post-endoscopic papillectomy ulcer was covered with clots and fresh blood. b Pulsatile bleeding was detected around the pancreatic stent (arrow). c Coagulation hemostasis was achieved using bipolar hemostatic forceps. d Self-assembling peptide was sprayed, and no further bleeding was observed.
To the best of our knowledge, this is the first report of endoscopic hemostasis using
bipolar forceps coagulation for endoscopic papillectomy-related bleeding. This device
is effective for pulsatile bleeding while preventing tissue injury to post-endoscopic
papillectomy ulcers.
