Long-Term Outcomes of Hemostatic Therapy for Gastrointestinal Variceal Bleeding and the Transition of Hemostatic Therapy: A Retrospective Study

Abstract

BACKGROUND Gastrointestinal varices are dilated submucosal veins in the gastrointestinal lumen associated with portal hypertension and represent important complications of liver cirrhosis (LC). Gastrointestinal variceal bleeding has serious life-threatening outcomes; although hemostatic therapy is possible in many cases, there are only a few studies reporting the detailed course of patients with variceal bleeding after hemostatic therapy and the transition of hemostatic therapy. This study aimed to evaluate the long-term outcomes of endoscopic hemostatic therapy for gastrointestinal variceal bleeding and of the transition of hemostatic therapy.METHODS A total of 125 patients who underwent emergency hemostatic therapy for gastrointestinal variceal bleeding between April 2006 and June 2020 were included. Data on the bleeding site, therapeutic method, primary therapeutic success rate, cumulative survival rates, factors associated with prognosis, recurrence rates, re-bleeding rates after treatment, and causes of re-bleeding were analyzed. Additionally, patients were classified into two groups: the previous term and the latter term. Patients’ background, therapeutic method, and treatment results were compared between the groups.RESULTS Overall, 94.4% had cirrhosis. The average Child-Pugh (CP) score (CPS) was 8.90. The rate of successful primary hemostasis was 98.4%, and 5.6% died within two weeks, all with a CPS ≥9. The respective one- and five-year survival rates for CP grade A/B were 81.3% and 55.4%, while those for CP grade C were 58.1% and 17.8%. CP grade C or hepatocellular carcinoma was significantly associated with poor prognosis. In total, 21.6% experienced variceal re-bleeding, and 62.9% of variceal re-bleeding cases were triggered by alcohol consumption. There was no significant difference in survival between patients with and without variceal re-bleeding. There was no significant difference in post-treatment survival between the previous and latter terms. In the latter term, the number of cases caused by alcohol consumption increased.CONCLUSIONS The hemostasis rate for variceal bleeding was high. Multidisciplinary treatment and continuation of proper management after treatment are crucial. Alcohol consumption increased variceal re-bleeding in the post-direct-acting antivirals era.
