M. Hashizume et al., SCLEROTHERAPY-RESISTANT ESOPHAGEAL-VARICES WITH ENORMOUSLY ENLARGED CEPHALAD COLLATERAL VESSELS PREDICTABLE USING PORTOGRAPHY, Hepato-gastroenterology, 42(5), 1995, pp. 551-556
Background/Aims: The most common cause of failure of sclerotherapy is
recurrent bleeding before eradication is complete. We investigated fac
tors which would make feasible prediction of cases where esophageal va
rices would be more difficult to eradicate. Patients and Methods: Seve
n hundred and seventy patients underwent endoscopic injection scleroth
erapy at Kyushu University Hospital from January, 1982 to June, 1989.
For 580 of these patients rue used the same sclerosant and a transpare
nt overtube. For 19 of 580 patients over two months were needed to era
dicate the varices (group 2), while eradication was complete in less t
han. one month in 64 patients (group 1). Results: There was a tendency
toward a lower platelet count and a higher indocyanine green. retenti
on rate in group 2, but with no statistically significant difference.
The number of sessions required for eradication of the varices was 8.1
+/-2.5 and the total volume of sclerosant used was 98.2+/-62.3 ml in,
group 2, and 3.0 and 47.0+/-10.9 ml, respectively, in group 1 (p<0.01)
. There was no significant difference in the number of sessions betwee
n the patients with large-sized and moderate-sized varices. Based on t
he extent of cephalad collateral vessels on the venous phase of celiac
or superior mesenteric angiography, the vascular pattern could be cla
ssified into three types; Grade III, the most developed type was prese
nt in 100% and 57.1 % on celiac and superior mesenteric angiography in
group 2, while the rates were 11.1% and 5.6% in. group 1 (p<0.05). Co
nclusions: This retrospective study shows that in patients with enormo
usly enlarged cephalad collateral vessels it may be difficult to eradi
cate the varices, and in such cases, preoperative portography is most
useful to predict whether or not esophageal varices can be eradicated.
