![]() ![]() Hemostatic forceps are devices that were developed initially for treatment and prevention of bleeding during endoscopic resection ( Fig. 1). 7 Of note, sales of the HPU-20 in the United States were discontinued in 2011, and the manufacturer has communicated its intention to discontinue sales of the compatible probes in 2019 (personal communication). 3 A power setting of 25 J to 30 J per pulse, using 4 to 5 pulses (total of 100-150 J) per station (before the probe position is changed) has been recommended for peptic ulcer bleeding. Once the pulse has been initiated, the duration of activation is predetermined and will deliver the entire amount of preselected energy. A foot pedal controls heat activation and irrigation. 7 The probe is placed directly at the site of the bleeding vessel, either perpendicularly or tangentially, with pressure applied for coaptive coagulation. The PTFE coating reduces adherence of the probe to tissue. The probe transfers heat from its end or sides, causing tissue coagulation. 3 The probes are reusable and are compatible with the HPU-20 (Olympus America, Center Valley, Pa, USA) power source. The heater probe comprises a PTFE-coated hollow aluminum cylinder with an inner heating coil and an irrigation port at the tip of a 230- to 300-cm 7F to 10F catheter.
