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: Various pressor agents are used to raise systemic vascular resistance (SVR) during liver transplantation. The aim of this study was to investigate the effect of liver denervation on hepatic hemodynamic responses to vasopressors. METHODS: This study was conducted in eight anesthetized dogs randomly assigned in to 4 groups [epinephrine-Low dose (L): 0.05 microgram/kg/min, epinephrine-High dose (H): 0.5 microgram/kg/min, ephedrine (D): 0.2 mg/kg, phenylephrine (P): 80 microgram/min]. One hour after surgical denervation of the liver, cardiac output, blood gases and hepatic blood flow were measured before and after administration of vasopressors with an electromagnetic flow meter. Oxygen consumption rate (hepatic artery plus portal vein oxygen delivery-hepatic vein oxygen delivery) was calculated. The Wilcoxon signed rank test and Kruskal-Wallis test were used for statistical analysis; The level of significance was assumed at the P < 0.05 level. Results are expressed as mean +/- SE. RESULTS: The resulting hemodynamic values were not significantly different between groups except for hepatic vascular resistance in the P group. Hepatic blood flow decreased significantly in the P and H groups, whereas it increased significantly in the L group. Hepatic oxygen consumption and Base Excess in hepatic venous blood after vasopressors were not significantly different between groups. These results mean there were no significant differences in hepatic oxygenation between groups. CONCLUSIONS: Various pressor agents can be used to raise SVR without jeopardizing hepatic oxygenation. However, phenylephrine and high dose of epinephrine are not recommended after liver transplantation because decreased hepatic blood flow might affect the intracellular oxygen environment adversely.

Surgery is the primary treatment for adenocarcinoma arising from Barrett's esophagus. However, in order to avoid the high risk of complications of surgical resection, many physicians try various endoscopic treatments in cases of early adenocarcinoma and high-grade dysplasia of Barrett's esophagus. Endoscopic submucosal dissection (ESD) is a recently highlighted technique because of its high rate of en bloc resection, but there is controversy about ESD because of the uncertain long-term effect. There is a high risk of local recurrence after endoscopic treatments especially in a long-segment Barrett's esophagus, but there are no reports about this in Korea. This case we report on shows that the early adenocarcinoma arising from a long-segment Barrett's esophagus was curatively removed by ESD, but recurred high-grade dysplasia was detected on the remnant Barrett's esophagus after one year. We report here on a case of recurred esophageal malignancy after successful endoscopic resection of adenocarcinoma from a Barrett's esophagus.

A feeding gastrostomy tube is used to provide chronic nutritional support for patients who have a swallowing disability. Serious complications associated with feeding gastrostomy are rare. However, dislocation of the gastrostomy tube into the duodenum can lead to serious complications. There have been 7 reports in which the gastrostomy tube used for enteral feeding was associated with acute pancreatitis. But there have been no reports of pancreatitis associated with feeding gastrostomy in Korea. Further, all the reported cases were associated with both pancreatitis and cholangitis secondary to the compression of the major papilla by the percutaneous endoscopic gastrostomy tube. To the best our knowledge, this is the first report of acute pancreatitis, without cholangitis, that was induced by the compression of migrating surgical gastrostomy tube. Herein, we report on a case of a 68-year-old Korean male diagnosed with acute pancreatitis, and this was induced by the migration of a surgical gastrostomy tube.

Intramural gastric abscess is a rare condition representing a localized form of suppurative gastritis. According to the extent of the disorder, suppurative gastritis is classified into diffuse and localized types. The diffuse or phlegmonous type is more common and involves the entire stomach with inflammation spreading to all layers from the submucosa. The localized form referred to as "intramural gastric abscess" accounts for 5% to 15% of cases. The pathogenic mechanism includes direct invasion by microorganisms and hematogenous spread from a distant source. Cases are usually diagnosed with a combination of imaging modalities such as ultrasound, computed tomography, endoscopic ultrasound, and esophagogastroduodenoscopy. Herein we report a case of intramural gastric abscess that developed following ingestion of a fish bone. It was successfully treated with endoscopic incision and drainage of pus.

Situs inversus totalis (SIT) is very rare autosomal recessive condition, and patients with SIT have complete mirror image reversal of the thoracic and abdominal viscera. There have been no case reports of esophageal bezoar in a patient with situs inversus totalis. Bezoars are retained concretions of indigestible foreign material, including food material, vegetable material and hair, and they are usually founded in the stomach, small intestine and rectum. Esophageal bezoars are very rare, but they are known to occur in patients with anatomical defects or esophageal motility disorders. The treatment of esophageal bezoar is usually based on endoscopic fragmentation and extraction, dissolution with papain, cellulose, pancreatic enzyme and/or Coca cola. We report here on a case of an endoscopically treated primary esophageal bezoar in a patient with situs inversus totalis, and the patient experienced no complications from the treatment.

BACKGROUND/AIMS: Dominant genotype of hepatitis A virus (HAV) in Korea had been known to be genotype 1A in 1990s. Recently, the epidemiologic change of HAV genotype was reported with an upsurge of acute hepatitis A in Korea. The aim of this study was to investigate the change of HAV genotypes and clinical characteristics in Gwangju and Jeonnam province. METHODS: From November 2008 to October 2009, a total of 82 patients with acute hepatitis A were enrolled prospectively. HAV genotype was determined using reverse transcriptase polymerase chain reaction and sequencing of the PCR products of VP1/2A region of HAV. RESULTS: HAV RNA was detected in 82% (67/82). The genotype IIIA (88%, 59 cases) was significantly more frequent than genotype IA (12%, 8 cases) (p< or =0.01). The subtypes of genotype IIIA were AJ299467 Norway (49%), HA-JNG04-09 Japan (27%), HS-14-12-00 Spain (22%) and H-122 Sweden (2%). The subtypes of IA were FH1 Japan (50%) and HA J04-3 Japan (50%). The substitutions of amino acid were more frequent in genotype IIIA than IA (p< or =0.01). There was no difference in the clinical characteristics between the patients with genotype IIIA and IA. CONCLUSIONS: Genotype IIIA was a dominant genotype of recent HAV infection in Gwangju and Jeonnam province. This study provides valuable epidemiologic information of genetic distributions of HAV in Korea.

BACKGROUND/AIMS: While endoscopic resection could be considered as the best choice for the treatment of small rectal carcinoid, the colonoscopic biopsies performed at the time of detection may lead to scar and ulcer formation and cause unpredicted difficulty in the endoscopic resection. This study was evaluated to analyze the relationship between the post-biopsy scar and the limitation of submucosal elevation for the endoscopic resection of rectal carcinoids. METHODS: Twenty two cases of rectal carcinoid which received prior biopsies before the endoscopic resection were retrospectively compared with 20 non-biopsied cases. All two groups were treated by endoscopic resection from January 2000 to December 2007. There was no difference in the clinical characteristics and endoscopic findings such as size and location between the two groups. RESULTS: The limited submucosal elevation was experienced in 17 cases (77%) in the biopsy group, significantly more frequent than 9 cases (45%) in the non-biopsy group (p=0.03). The colonoscopic findings which contribute to difficult submucosal elevation were the depressive scar formation after biopsy, the size less than 5 mm in the biopsy group, active ulcer formation after biopsy. Regarding the resection method, endoscopic submucosal dissection was frequently adopted (23% vs. 5%) in the biopsy group. The frequency of endoscopic piecemeal resection in biopsy group was higher than non-biopsy group (23% vs 10%), and all cases were subsequently resected by other endoscopic methods. CONCLUSIONS: The post-biopsy scar can interfere with successful submucosal elevation for endoscopic resection of rectal carcinoids. The number of forcep biopsy should be minimized in the diagnostic colonoscopy when endoscopic resection is planned rectal carcinoids.
