Introduction: Argon plasma therapy (APC) is an option for chronic hemorrhagic radiation proctitis. Some factors may influence in the number of sessions to resoluteness of bleeding. 
Objective: To describe the factors associated to the number of therapeutic sessions with argon plasma to achieve resoluteness of bleeding in patients with chronic hemorrhagic radiation proctitis. 
Method: An observational study was made to describe the factors associated to the number of therapeutic sessions with argon plasma to achieve resoluteness of bleeding in 38 patients with chronic hemorrhagic radiation proctitis treated and followed up in the National Center for Minimal Access Surgery, Havana, Cuba from 2012 to 2015. Values of mean and percentage were calculated; different statistical tests were used to evaluate association between some variables. 
Results: Only one relationship was found: a higher number of therapeutic sessions was associated with the highest percentage of affected circumferential mucosa (p=0.012), which means that the greater circumferential damage will be greater the number of sessions necessary to achieve the resolutivity of the bleeding. There was no evidence to suggest a statistically significant association between the rest of the variables studied and the number of therapeutic sessions of Argon plasma used. 
Conclusions: APC is a good therapeutic alternative for radiation proctitis. The highest percentage of mucosa circumferentially affected with lesions influences the need to apply a greater number of therapeutic sessions to resoluteness of bleeding.
