M. Umehara et al., Sclerotherapy plus ligation versus ligation for the treatment of esophageal varices: a prospective randomized study, GASTROIN EN, 50(1), 1999, pp. 7-12
Background: We devised a new combined method of endoscopic variceal ligatio
n and injection sclerotherapy, namely, endoscopic scleroligation, for the t
reatment of esophageal varices. The aim of this prospective randomized tria
l was to compare endoscopic scleroligation with endoscopic variceal ligatio
n alone with regard to efficacy, complications, variceal recurrence, and su
rvival.
Methods: Fifty-one patients with cirrhosis and esophageal varices were rand
omly assigned to be treated by endoscopic scleroligation (n = 25) or endosc
opic variceal ligation (n = 26). In the initial session in the endoscopic s
cleroligation group, endoscopic injection sclerotherapy was performed with
injection of 5% ethanolamine oleate around the lower esophagus to obliterat
e the feeding veins. This was followed by endoscopic variceal ligation from
the injection site to the most orad varix. In subsequent sessions, endosco
pic injection sclerotherapy was performed with 1% polidocanol. In the endos
copic variceal ligation group, that procedure was performed in all treatmen
t sessions.
Results: Both methods were equally effective in achieving complete eradicat
ion of esophageal varices. Among the cases in which complete eradication wa
s achieved, the 1- and 3-year cumulative recurrence rates in the endoscopic
scleroligation group (9.5%, 22.1%) were significantly lower than those in
the endoscopic variceal ligation group (61.9%, 72.2%) (p < 0.01). The survi
val rates and incidences of treatment-related complications have been simil
ar among patients treated by both methods.
Conclusions: Endoscopic scleroligation is superior to endoscopic variceal l
igation in preventing variceal recurrence.
