RESUMO
Several forms of colonic complications are rarely observed during the clinical course of acute pancreatitis, and potentially fatal in some cases. Colonic lesions associated with acute pancreatitis can be divided into several groups from a pathogenic point of view. Possible pathogenesis includes 1) spread of pancreatic enzymes through the retroperitoneum to mesocolon, causing pericolitis, 2) external inflammatory compression by mesocolic mass secondary to necrosis of fatty tissue, and 3) hypotension due to shock, and thrombosis of mesenteric arteries. These might lead to colonic infarction, fistula formation, perforation, and obstruction during follow-up. We report two cases of colonic obstruction following acute pancreatitis with possible different mechanisms and review Korean cases. One patient developed colonic obstruction due to severe necrotizing pancreatitis, possibly as a result of pericolitis, and the other developed stenosis as a result of ischemic colitis induced by acute pancreatitis.

Autoimmune chronic pancreatitis is a disease characterized by diffuse swelling of the pancreas, irregular narrowing of the main pancreatic duct and elevated levels of serum IgG, and lymphoplasmacytic infiltration is observed on histologic examination. Steroid therapy can dramatically reverse the clinical symptoms and the histologic and radiologic findings. It is known that recurrence is very rare after successful steroid treatment. Furthermore, there have not yet been any reports about a case that relapsed during maintenance therapy with low dose steroid. We experienced a rare case of autoimmune chronic pancreatitis that relapsed despite maintenance therapy with low-dose steroid, and the patient again responded to high-dose steroid.

Histamine H2-receptor antagonists are commonly used in many clinical conditions, and their hepatotoxicity has been reported occasionally.However, cholestatic hepatitis induced by nizatidine is very rare. Here, we report a young female patient with severe cholestatic hepatitis associated with nizatidine use. She had taken nizatidine to manage asymptomatic reflux laryngitis by an otonasolaryngology doctorfor about 20 days. After about 15 days of nizatidine administration, jaundice developed and continued for more than2 months withmaximal serum total bilirubin reaching 17.5 mg/dL, in spite of the discontinuation of medication. Liver specimen obtained by needle biopsy revealed severe centrilobular cholestatic hepatitis. Her liver function improved slowly and serum total bilirubin decreased down to 1.7 mg/dL after months later from the development of jaundice. As far as our knowledge, this is the second case of nizatidine- induced cholestatic hepatitis reported in the literature.

Polyarteritis nodosa (PAN) is a multi systemic disease, occasionally described as limited forms of the disease. Localized form of PAN is usually associated with better prognosis. We describe unusual two cases of patients who has suffered from sudden onset of low extremity pain by localized forms of polyarteritis nodosa. Magnetic resonance imaging of the lower legs showed abnormal signal intensity of the suspected muscle. Acute necrotizing arteritis with myopathy has been revealed by muscle biopsy. The symptom of the patient has been improved soon after corticosteroid administration. Muscle biopsy of symptomatic muscles or MRI-directed biopsies can be useful to diagnose this case as PAN with localized myopathies.

BACKGROUND/AIMS: To evaluate the clinical outcomes of the percutaneous cholangioscopic ethanol injection in the hepatocellular carcinoma (HCC) invading the bile duct, we conducted a retrospective study. METHODS: Ten patients who received the percutaneous cholangioscopic ethanol injection were selected patients were diagnosed as HCC invading the bile duct between January 1998 and February 2004. Treatment response, complications, survival or death and survival time were analyzed. RESULTS: Ten patients received mean of 5.3 sessions (range 2~19) of cholangioscopic ethanol injection. Eight patients had decreased tumor mass, and the rest 2 patients had no response. Complications were pain (n=10), hemobilia (n=6: bleeding was minimal), cholangitis (n=2), bile duct rupture (n=1), and bile duct stricture (n=1). Nine patients died from severe hepatic failure and sepsis, one patient has survived for 19 months as of now. Median survival time was 5 months (range 2~19 months). Percutaneous transhepatic biliary drainage (PTBD) could be removed in two patients. CONCLUSIONS: Percutaneous cholangioscopic ethanol injection in HCC invading the bile duct showed size reduction of mass. PTBD could be no longer needed in some patients. However, supportive cares such as PTBD may be appropriate considering their short survival period and risk of procedure.

BACKGROUND: In Korea, the most common cause of acute viral hepatitis used to be the hepatitis B virus, but now the etiology of acute viral hepatitis seems to be changing. We investigated the etiology of newly developed acute viral hepatitis for the last 3 years. METHODS: We retrospectively reviewed the medical records of patients, who visited Asan Medical Center for jaundice during recent 3 years. Among them, one hundred eighty six patients were diagnosed as acute viral hepatitis by typical clinical feature and positive results in any one of the following tests: IgM anti-HAV, IgM anti-HBc, HCV PCR, and IgM anti-HEV. RESULTS: The proportion of acute viral hepatitis A, B, C, and E were 49.5% (n=92), 45.2% (n=84), 3.8% (n=7), and 1.6% (n=3), respectively. The patients' age of acute hepatitis A (29.1 +/- 1.75 years) was significantly younger than that of acute hepatitis B (38.2 +/- 3.07 years) (p<0.001). There were 10 cases of fulminant hepatic failure, all of which were caused by hepatitis B virus. Of seven patients diagnosed as acute hepatitis C, three patients were treated with interferon-alpha and ribavirin, and all achieved sustained virologic response. Three patients, who were diagnosed as acute hepatitis E, recovered spontaneously. CONCLUSION: Nowadays, the most common causes of acute viral hepatitis in Korea are in the order of the hepatitis A virus and the hepatitis B virus. The most prevalent age of acute hepatitis A is the 20th, while acute hepatitis B is most common in the 30th. Although the acute hepatitis C and E seems to be rare, they do occur sporadically in Korea.

Here, a case of a patient with incidental finding of a carcinoid tumor of the ampulla of Vater, who was treated with endoscopic snare papillectomy, is reported. A 62-year-old male was admitted to our hospital due to a carcinoid tumor of the ampulla of Vater, which was found during follow-up endoscopy after an endoscopic mucosal resection of early gastric cancer. No lymphadenopathy or visceral metastasis was found on an abdominal CT scan, In-111 octerotide scan and EUS. The ampulla was then en bloc removed by endoscopic snare papillectomy. The resected specimen revealed a 0.7 X 0.5 X 0.1 cm sized carcinoid tumor. All margins of resection were negative for tumor. After six months of follow-up, there was no evidence of recurrence and metastasis, either endoscopically or radiologically. To our knowledge, this case is the first report of an ampullary carcinoid tumor treated by endoscopic snare papillectomy in Korea.

BACKGROUND/AIMS: The management of small-bowel perforations associated with endoscopic retrograde cholangiopancreatography (ERCP) or endoscopic sphincterotomy (EST) is still controversial. The purpose of this study was to analyze the treatment and outcome of patients with ERCP-related perforations in a single tertiary medical center. METHODS: Of 18,379 cases of ERCPs performed between January 1990 and December 2003, twenty-six patients (0.14%) with perforation were identified and medical chart were reviewed retrospectively. RESULT: EST were performed in 10,231 patients and perforation occurred in 18 patients. Four out of 18 patients with small-bowel perforation related to EST underwent surgical operation and the rest 14 patients recovered with conservative treatment alone. Of the rest 8 perforation patients unrelated to EST, perforation occurred during the insertion of endoscope in 7 patients and catheter manipulation in 1 patient. All but one perforations associated with mechanical injury by endoscope itself were managed with an emergent laparotomy, and the one patient with perforation related to catheter manipulation recovered with conservative treatment. CONCLUSIONS: A small-bowel perforation related to endoscope per se usually required a surgery, but sphincterotomy related perforations rarely did so. The prevalence and mortality rate of small-bowel perforations associated with ERCP and/or EST were 0.14% and 0%, respectively, in a single tertiary medical center.
