The clinical syndrome of venoocclusive disease of the liver is one of several manifestations of regimen-related toxicity that can occur after high-dose cytoreductive therapy. Hepatic dysfunction after bone marrow transplantation may result from a number of causes such as pretransplant chemoradiation, graft-versus host disease, drugs for prophylaxis of graft-versus host disease, venoocclusive disease, various infections, and infiltration of recurrent malignancy. The clinical distinction of these causes may be difficult and the treatment of each cause is also quite different. Therefore the diagnosis of veno-occlusive disease is important. Veno-occlusive disease affects zone 3 of the liver acinus and produces a syndrome of jaundice, painful hepatomegaly, and fluid retention. Veno-occlusive disease occurs in up to 50% of the patients who undergo BMT and is usually associated with a high mortality rate. In Korea, there are a few case reports on venoocclusive disease after BMT which were only confirmed by clinical symptoms. This is a first report of two cases of hepatic veno-occlusive disease after allogenic BMT, which were proven by laparoscopic liver biopsy in our country.

BACKGROUND AND AIMS: The major complications of reflux esophagitis are stricture formation and Barrett's esophagus. In Korea, the incidence of these complications is low and most patients with reflux esophagitis undergo a mild clinical course. The purpose of this study was to investigate patterns of acid reflux and esophageal motility in mild reflux esophagitis in Korea. METHODS: Using conventional manometry and 24-hour ambulatory pH monitoring, we were investigated esophageal motility and patterns of gastroesophageal reflux in 41 patients with reflux esophagitis Savary-Miller (S-M) Ib using on endoscopy. The total supine, and upright reflux periods, as well as frequency and duration of reflux episodes were determined from the 24-hour pH monitoring record using standard software. Pathologic reflux was defined when the percentage of the total time with pH less than 4 (acid exposure time) exceeded 4%. RESULTS: Pathologic reflux was observed in 17 patients (41.5%), who were categorized into upright refluxers (70.6%), supine refluxers (11.8%), and combined refluxers (17.6%). Patients with reflux esophagitis did not differ in lower esophageal sphincter pressure from the normal subjects. There were two patients (4.9%) with a lower esophageal pressure > or =10 mmHg and four patients (9.8%) with hiatal hernia. Failed peristalsis was seen in 4 patients (9.8%). CONCLUSIONS: A high proportion of upright reflux and low incidence of esophageal peristaltic dysfunction may contribute to the low incidence of stricture formation and Barrett's esophagus in patients with mild reflux esophagitis in Korea.
