Summary

Background:

A second endoscopic method added to injection therapy is recommended for high-risk bleeding peptic ulcers. Many endoscopic devices have been proved as useful hemostatic instruments, whereas the hemostatic efficacy of argon plasma coagulation (APC) has not been widely investigated.

Aim:

This study was designed to know whether additional APC treatment could influence the hemostatic efficacy after endoscopic injection therapy in treating high-risk bleeding ulcers.

Methods:

From October 2010 to January 2012, eligible patients who had high-risk bleeding ulcers were admitted to our hospital. They prospectively randomly underwent either APC therapy plus distilled water injection or distilled water injection alone. Pantoprazole infusion was conducted during the fasting period after endoscopy and orally for 8 weeks to encourage ulcer healing. Episodes of rebleeding were retreated with endoscopic combination therapy. Patients who did not benefit from retreatment underwent emergency surgery or transarterial embolization (TAE).

Conditions

  • Bleeding Ulcers

Interventions

DEVICE

Argon plasma coagulation

Argon plasma coagulation therapy was realized by an Olympus electrosurgical unit/APC unit (PSD-60/Endoplasma, Olympus Corporation, Tokyo, Japan), and its catheters were 2.3mm and 3.5 mm equipped with different endoscope channels.7 APC treatment used a coagulation mode at gas flow/power settings of 1.5L/min and 40 watt for duodenal ulcers and 40-60 watt for gastric ulcers.10 Operative distance between the probe and target bleeding ranged from 2 to 8 mm. Air warranted to be sucked frequently at endoscopy in an attempt at decrease of APC-induced smoke and gastric decompensation, with appropriate treatment of high-risk bleeding ulcers.

DEVICE

Distilled water

Distilled water was then applied in aliquots of 0.5-2.0 mL, at and around the site of target bleeding, up to 25.0 ml if necessary. Injection amount was determined by endoscopists according to ulcer or vessel size and its location.
