Endoscopic injection sclerotherapy (EIS) is a major therapeutic modality for the treatment
of patients with bleeding from ruptured esophageal varices [1 ]. In addition, it has been demonstrated that prophylactic sclerotherapy in cirrhotic
patients with known varices can reduce the rate of subsequent bleeding and improve
survival [2 ]. The complications of endoscopic sclerotherapy include, for example, esophageal
ulceration and esophageal perforation [3 ]. However, few reports have focused on the development of gastric ulcers following
sclerotherapy [4 ].
A 45-year-old man was admitted to our hospital with liver cirrhosis due to hepatitis
virus B and esophageal varices. His varices were classified as LiF2 CbRC(+)Lg-cf(+) according to the general rules for study of portal hypertension [5 ]. About 5 months prior to admission, he had undergone three uneventful sessions of
sclerotherapy for risk-associated esophageal varices. At 3 days after admission, he
underwent EIS; a total of 10 ml of 5 % ethanolamine oleate was injected into several
large varices at different sites under radiographic guidance (Figure [1 ]). The patient had a moderate degree of upper epigastric discomfort following the
procedure. The abdominal pain increased and the patient vomited blood on the morning
after the procedure. A subsequent endoscopy examination revealed a large gastric ulcer
in the lesser curvature of the gastric body (Figure [2 ]). A computed tomography examination also showed a low-density area in the lesser
curvature of the gastric body. The giant gastric ulcer, which responded to conservative
therapy, appeared to be healing at 1 month after the sclerotherapy.

shows the left gastric vein through the fundic plexus; however the left gastric artery
branch is not visible.

body, 1 day after the EIS.
In view of its location, the giant gastric ulcer may have formed because of ischemia
as a result of arterial obstruction by the sclerosant. Only one previous report has
focused on the formation of gastric ulcers following sclerotherapy. Asano et al. [4 ] reported that a gastric arterial branch was detected in a portion of an ulcer by
means of varicealography; however we did not observe any gastric arterial branches
in the present case. Giant gastric ulcer is a very rare but serious complication of
sclerotherapy.
