RESUMO
BACKGROUND/AIMS: An ectopic opening of the common bile duct (CBD) into the duodenal bulb is known to cause biliary tract diseases or peptic ulcer. Yet such a case is extremely rare and the clinical significance of this malformation has not yet been clarified. METHODS: Ten patients with an ectopic opening in the duodenal bulb and who were treated at 4 hospitals in the Chungcheong province area were enrolled. Their clinical and radiographic features and the treatment for their combined biliary diseases were retrospectively analysed. RESULTS: The mean age of the ten patients was 73 years (range: 38~84 years, 8 men, 2 women) Eight of 10 patients had clinical signs and symptoms (RUQ abdominal pain: 5, epigastric pain: 3, fever: 3, Melena: 1). The two patients without symptoms were incidentally found to have an ectopic orifice during the evaluation for bile duct dilatation and a regular health check-up, respectively. Nine had duodenal ulcer scars or bulb deformities. Four had active duodenal ulcers and one of them had bleeding from the active duodenal ulcer, which was treated by endoscopic sclerotheraphy. Six of the 10 patients (60%) had biliary tract diseases (CBD stones: 4, cholangitis without CBD stone: 1, IHD stone: 1). Cholangiography was used for evaluation in 9 patients, and it showed dilatation of the CBD or IHD in 7 (78%), a tapered common bile duct at the distal CBD in 7 (78%) and a hook-shaped distal CBD in 8 (89%). Six patients' biliary tract diseases were treated endoscopically (ERCP: 4, PTCS: 2). Duodenal perforation occurred in 1 (10%), who was successfully managed by medical treatment. CONCLUSIONS: An ectopic opening of the CBD in the duodenal bulb is frequently associated with recurrent duodenal ulcer and biliary tract disease. Combined biliary tract disease can be successfully treated endoscopically.

Granular cell tumor is relatively uncommon, it is usually benign and it can be located anywhere throughout the body. It is uncommon in the digestive tract, and especially in the colon and rectum. The endosonographic features of granular cell tumor are usually a relatively hypoechoic, heterogenous lesion in the submucosa, but this tumor has rarely been reported in the colon. We report here on two cases of granular cell tumors of the colon that were observed by using endoscopic ultrasonograpy for making the differential diagnosis of a submucosal tumor and these tumors were confirmed by microscopic examinations after endoscopic mucosal resection.

Bezoars are collections or concretions of indigestible foreign material that accumulate and coalesce in the gastrointestinal tract. Treatment options include dissolution with enzymes, endoscopic removal or aspiration, and surgery. The outcome differs according to the treatment method. A 57-year-old man was admitted with a 1-month history of epigastric pain. On gastrofiberscopy, an approximately 2-cm deep ulcer was seen on the lesser curvature of the antrum and three huge bezoars were found. In order to remove the first one, we injected Coca-Cola into it directly. It took 20 minutes to cut up and 1 hour to remove completely. To decrease the procedure time, we changed the injection fluid to urokinase for the remaining two bezoars. It took 9 and 10 minutes to cut up the second and third bezoars, respectively, and 1 hour to remove them completely. We report a case of phytobezoars treated successfully by endoscopic injections of Coca-Cola and urokinase.

Gastrointestinal stromal tumor (GIST) is an uncommon mesenchymal tumor of the gastrointestinal tract and is generally located in the stomach and small intestine. They usually present with abdominal pain, gastrointestinal bleeding, and palpable mass. Some patients present with rare symptoms that are more common in malignant GIST. Malignant GIST combined with a liver abscess has not been reported yet in the literatures. We report a case of 67-year-old woman who suffered from liver abscess combined by malignant GIST with central necrosis and fistula in the ileum. She complained of fever, chills, and abdominal pain. Abdominal CT scan showed huge liver abscess and ileal mass with air pocket. Small bowel series showed contrast material filling into the ileal GIST mass. An operation was performed and the final diagnosis was malignant GIST of the ileum with invasion into the sigmoid colon and urinary bladder.

BACKGROUND: Nitric Oxide (NO) induced by NO synthase is known to be associated with hyperdynamic circulation and collateralization by vascular remodeling in patients with cirrhosis. METHODS: To assess the significance of peripheral NO activity in patients with cirrhosis, we measured the production of NO metabolites, nitrate and nitrite, using the nitrate/nitrite colorimetric assay with Griess reagents in the peripheral venous blood of 95 cirrhotic patients with or without clinical portal hypertension (PHT), and in the peripheral venous blood of 32 control patients without liver disease. RESULTS: The peripheral NO activities in cirrhotic patients with clinical PHT, cirrhotic patients without clinical PHT, and non-liver disease control patients were 86.1+/-40.6 micro mol/L, 83.5+/-47.2 micro mol/L and 52.3+/-38.4 micro mol/L, respectively. NO activity was significantly higher in cirrhotic patients than in non-liver disease control patients (p<0.05), while there was no significant difference of NO activity between the cirrhotic patients with or without clinical PHT. Peripheral NO activities in cirrhotic patients with Child-Pugh classification A, B, and C were 84.9+/-45.5 micro mol/L, 81.9+/-53.2 micro mol/L and 86.4+/-39.8 micro mol/L, respectively; these results were not significantly different. A significant correlation of NO activity with the biochemical profiles of the serum albumin level, bilirubin level and prothrombin time were not defined. CONCLUSIONS: Peripheral NO activity was increased in cirrhotic patients, but it did not reflect the degree of clinical portal hypertension and the function of the hepatic reserve in this study. For a precise analysis of the association of NO and hyperdynamic circulation with collateralization in cirrhosis, intrahepatic or portal NO activity might be considered rather than peripheral NO activity.

Rectal carcinoid tumors are relatively uncommon and make up 1~2% of tumors found in the rectum. Approximately 50% of the tumors are asymptomatic and are found incidentally. In most cases, the tumors are slowly growing in nature and thus have a favorable outcome. Anywhere from 66 to 80% of rectal carcinoid tumors are smaller than 1 cm and rarely metastasis. However, malignant behavior, such as invasion to the muscle wall, and metastasis to a distant organ, may be seen infrequently with tumors greater than 2 cm in size. The liver is the most common site of a metastasis. We experienced a case of a 1 cm sized small rectal carcinoid tumor with multiple liver metastases.

Lamivudine is widely used for the treatment of chronic hepatitis B infection because of it's remarkable antiviral efficacy and safety. We report a case of severe skin eruption caused by lamivudine. A 47-year-old female was admitted because of jaundice and itching sensation. She was diagnosed as chronic hepatitis B infection a few years ago but did not receive any specific treatment. Laboratory data showed acute deterioration of chronic hepatitis B infection. We prescribed lamivudine as a rescue therapy. Her general condition improved and lab data showed improvement in liver function test thereafter. However, she complained of severe skin eruption and itching sensation a few days after the discharge. We stopped lamivudine because the symptoms did not improve despite the use of anti-histamine. Skin biopsy showed interface dermatitis. After stopping lamivudine, her symptoms improved. However, the skin eruption developed again after lamivudine was restarted. Adefovir was used instead, and the patient did not experience any further skin problems since then.
