N. Nagamine et al., A PILOT-STUDY ON MODIFIED ENDOSCOPIC VARICEAL LIGATION USING ENDOSCOPIC ULTRASONOGRAPHY WITH COLOR DOPPLER FUNCTION, The American journal of gastroenterology, 93(2), 1998, pp. 150-155
Objective: The purpose of the study was to evaluate feasibility of mod
ified endoscopic variceal ligation (EVL), namely the ''intensive ligat
ion'' method, using endoscopic ultrasonography with color Doppler func
tion (EUS-CD). Methods: Forty-five patients with esophageal varices we
re treated by modified EVL. Variceal hemodynamics in 38 patients were
examined using EUS-CD, which showed abdominal hemodynamics in detail u
nder physiological renditions before and after the modified procedure,
Results: 1) The median number of treatment sessions was 3.2, and 41 O
-rings on average were required per individual patient. 2) The median
nonrecurrence period after treatment was 18 months (Kaplan-Meier metho
d), 3) Nine patients with a good response tea modified EVL did not hav
e recurrences for 16.9 +/- 2.8 months, and five with a poor response h
ad recurrences at 5.8 +/- 2.2 months, Gastric varices were related to
the response to modified EVL (p < 0.05, Mann-Whitney's U test), 4) Min
or complications ire modified EVL, as well as standard EVL were experi
enced; however, we had a patient with the development of meningitis, w
hich was a major septic complication, 5) Before modified EVL, EUS-CD d
emonstrated that good responders had undeveloped (grade I) gastric var
ices in flue of nine (56%); however, poor responders had developed (gr
ade III) gastric varices in four of five (80%) (p < 0.05, Mann-Whitney
's U test], 6) After modified EVL, EUS-CD revealed that six of nine (6
7%) good responders and one of five (20%) poor responders showed a dec
rease in color signals in supplying veins; however, none of the former
(0%) and three of the latter (60%) showed art increase (p < 0.05, Man
n-Whitney's U test], Conclusion: Modified EVL was safe and effective,
at least with regard to intermediate-term outcome, especially when tre
ating patients with undeveloped gastric varices revealed by EUSCD, Bot
h goad and poor responders showed no exacerbation of gastric varices a
fter the modified procedure, ultrasonographically as well as endoscopi
cally. (C) 1998 by Am, Coil, of Gastroenterology).
