Background:
The therapeutic schedule in bleeding esophageal varices is today established: emergency endoscopy with sclerotherapy or ligation combined with somatostatin and decreasing portal pressure drug followed by repetitive sclerotherapy or ligation. But the approach to varices that do not bleed is not clear.
Methods:
The authors submit the results of a 6-year sclerotherapeutic program. Since January 1989 they have treated 421 patients with varices and have together performed 4,115 endoscopic sclerotherapeutic procedures. Among the 421 patients 95 were treated during acute bleeding and 254 were treated after first bleeding; in 72 patients prophylactic sclerotherapy (PSG) was performed.
Results:
The procedure was indicated, when grade III or IV varices or high-risk signs and/or hepatic venous pressure gradient (HVPG) > 15 in grade II varices were observed. Prophylactic therapy (not-treated group-NTG) refused next 31 selected patients. The mean follow-up time was 32 months in the PS group and 28 months in NTG (n.s.). Fifteen PSG patients died (21%), while the mortality among the NTG patients (13 = 42% patients) was significantly higher (P < 0.02).
Conclusions:
We recommend prophylactic sclerotherapy with 1% polidocanol in patients with advanced varices in liver cirrhosis of varied etiology. We emphasize the need to perform these procedures in a department with adequate experience, where at least 100-200 sclerotherapies per year are performed.
