BACKGROUND AND AIM: To demonstrate the effect of endoscopic injection sclerotherapy (EIS) with argon plasma coagulation (APC) as a primary/secondary prophylaxis for esophageal varies (EV) on portal hemodynamics and long-term outcomes in cirrhosis. METHODS: This prospective study included 48 cirrhotic patients (64.5 ± 11.4 years; 26 bleeders, 22 non-bleeders). Post-treatment outcomes (EIS and APC; median observation period, 12.8 months for recurrence and 21.1 months for prognosis) were evaluated with respect to the findings of hepatic venous catheterization, Doppler ultrasound, and endoscopic ultrasonography (EUS). RESULTS: All patients showed EV eradication after endoscopic treatment, and a decreased frequency of a patent left gastric vein (pre: 83.3%, post: 27.1%, P < 0.001). However, hepatic venous pressure gradient (HVPG, mmHg) remained unchanged after the treatment, pre: 16.1 ± 3.6, post: 15.6 ± 3.8 (P = 0.269). Cumulative variceal recurrence/rebleeding rates were 25.5%/5.6% and 62.4%/23.1% at 1 and 3 years, respectively. Post-treatment EUS finding, area of submucosal vessels in the cardia ≥12 mm2 was the only significant factor for variceal recurrence (hazard ratio 9.769, 95% confidence interval 3.046-31.337; P < 0.001). Cumulative recurrence rate was significantly higher in patients with area of submucosal vessels in the cardia ≥12 mm2 (58.3% at 1 year and 100% at 3 years) than in those without (11.4% at 1 year and 40.9% at 3 years, P < 0.001). Cumulative overall survival rates were 95.2% and 71.9% at 1 and 3 years, respectively, showing no significant relationship with HVPG. CONCLUSION: EIS with APC for EV is unlikely to have a significant influence on portal pressure.
