A prognostic evaluation of endoscopic intravariceal injection sclerotherapy for esophageal varices.
Eighty cases of endoscopic injection sclerotherapy for esophageal varices were retrospectively studied to evaluate their prognoses. These cases were evaluated in terms of post-therapeutic bleeding, survival rates and causes of death. Post-therapeutic bleeding occurred in 50% of the emergency cases (26 cases), 25% of the elective cases (16 cases) and 23.7% of the prophylactic cases (38 cases). The frequency of post-therapeutic bleeding was significantly lower in cases with variceal obliteration than in cases without obliteration. An evaluation of the survival rates by the Kaplan-Meier method revealed that poor prognostic factors in sclerotherapy cases were emergency cases, Child's C group, post-therapeutic cases with unsuccessfully obliterated varices, and cases with post-therapeutic bleeding. Concerning early death within 7 days after sclerotherapy, 4 emergency cases died from initial variceal bleeding despite sclerotherapy. Three of these 4 were hepatocellular carcinoma cases, and all 3 cases had tumor thrombi of the portal vein. We recommend prophylactic sclerotherapy from the standpoint of the prognosis after sclerotherapy. However, in the bleeding cases of hepatocellular carcinoma in Child's C group complicated by tumor thrombi of the portal vein, overly enthusiastic application of the therapy should be avoided.
