L. Laine et al., ENDOSCOPIC LIGATION COMPARED WITH SCLEROTHERAPY FOR THE TREATMENT OF BLEEDING ESOPHAGEAL-VARICES, Annals of internal medicine, 119(1), 1993, pp. 1-7
Objective: Comparison of the safety and efficacy of endoscopic sclerot
herapy and ligation for the treatment of bleeding esophageal varices.
Design: Randomized, controlled trial. Setting: An urban county hospita
l. Patients: Patients with clinically severe bleeding from esophageal
varices. Intervention: A total of 77 patients were randomly assigned t
o receive sclerotherapy or ligation at the initial endoscopic examinat
ion. Treatment was repeated weekly until variceal obliteration was ach
ieved. After eradication, patients had endoscopic examinations every 3
months or for any episode of rebleeding. Recurrent varices were treat
ed with the originally assigned form of endoscopic therapy. Measuremen
ts: Patients were assessed for further bleeding, for transfusion requi
rements, for time in hospital, for variceal eradication, for number of
treatment sessions required, for complications, for treatment failure
, and for risk of death. Results: Rebleeding tended to be less frequen
t with ligation than with sclerotherapy: 10 of 38 (26%) compared with
17 of 39 (44%) (difference, 17% [95% CI, -4% to 38%]), but results in
the two groups were comparable for blood transfusions, for length of h
ospital stay, and for risk of death. Comparison of Kaplan-Meier estima
tes of time to rebleeding and death showed no statistical differences
between treatments. Complications were less common in the ligation gro
up: fewer patients in the ligation group had esophageal strictures (0
of 38 compared with 13 of 39 [33%]; P < 0.001) and had complicated eso
phageal ulcers (1 of 38 [2.6%] compared with 6 of 39 [15%]; P = 0.11).
In addition, fewer ligation treatments were required to achieve varic
eal eradication (4.1 +/- 0.3 compared with 6.2 +/- 0.4; P < 0.001). Co
nclusion: Endoscopic ligation causes statistically fewer local complic
ations than sclerotherapy and achieves variceal eradication more rapid
ly. Ligation is a viable alternative to sclerotherapy and may have som
e advantages as a treatment for bleeding esophageal varices.
