[Significance of the initial status of the patient for the effectiveness of laser therapy in peptic ulcer].

An association of 8 signs characterizing pretreatment condition of patients with duration of gastroduodenal ulcer healing was statistically evaluated for 220 patients subjected to endoscopic laser therapy. The duration of the mucosal healing correlated with initial diameters and depth of the lesion, stage of its reverse transformation, clinical pattern. It is established that prognosis of laser therapy effectiveness based on original clinico-endoscopical evidence is feasible.
