To compare the efficacy, safety and number of sessions of bipolar eletrocoagulation (BEC) and argon plasma coagulation (APC) in the management of the bleeding telangiectasias from chronic radiation coloproctopathy (CRCP).
Thirty patients with active bleeding from telangiectasias were enrolled in two groups (15 BEC and 15 APC) and classified according of Saunders score. BEC settings were 50 W and APC settings were 40 W and 1.0 l/min. Colonoscopy was the first exam to rule out synchronous lesions and follow-up was performed with sigmoidoscopies. Clinical cure was defined as cessation of bleeding and endoscopic cure was determined by absence of telangiectasias. Failure was defined whenever more than 7 sessions or other therapy was necessary.
Thirty patients with active and chronic hematochezia from radiation telangiectasias were randomized in two groups :
- fifteen patients in group 1- bipolar eletrocoagulation (BE) and
- fifteen in group 2 - argon plasma coagulation(APC). For inclusion in the study, all patients were required to have active (at least one episode last week) and chronic (persist or appear 6 months after the conclusion of radiotherapy) rectal bleeding. Between May 2005 and April 2008, patients were treated and followed at the Endoscopy Unit in the São Paulo Hospital (UNIFESP).

Chronic radiation proctitis (CRP) develops in 5-15% of patients after pelvic radiatiotherapy with rectal bleeding as the main symptom. Reports suggest that Argon Plasma Coagulation (APC) can be an eff...
Argon plasma coagulation (APC) is a standard modality for the treatment of gastrointestinal bleeding. However, there are no metrics to assess technical proficiency. We aimed to determine if a Quick AP...
A method of tissue ablation and bleeding control that uses argon plasma (ionized argon gas) to deliver a current of thermocoagulating energy to the area of tissue to be coagulated.
Ionized gases, consisting of free electrons and ionized atoms or molecules which collectively behave differently than gas, solid, or liquid. Plasma gases are used in biomedical fields in surface modification; biological decontamination; dentistry (e.g., PLASMA ARC DENTAL CURING LIGHTS); and in other treatments (e.g., ARGON PLASMA COAGULATION).
Argon. A noble gas with the atomic symbol Ar, atomic number 18, and atomic weight 39.948. It is used in fluorescent tubes and wherever an inert atmosphere is desired and nitrogen cannot be used.
