, Tae Hun Kim, Kwon Yoo, Ye Ji Han, Jeong Eun Choi, Ji Yoon Kim, Min-Sun Cho Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease that may progress to end stage liver cirrhosis. Benefits of ursodeoxycholic acid (UDCA) treatment has been investigated through large clinical studies. However, most of the studies were done in western countries and recent increase in prevalence of this relatively uncommon chronic liver disease draws attention in Korea. As early UDCA treatment effectively prevent the grave consequences of PBC progression, early diagnosis and lifelong management with UDCA is important. This study was designed to investigate the clinical features of PBC and response rates of UDCA treatments in Ewha Womans University Medical Center.
Clinical data of PBC patients diagnosed between 2001 and 2014 at Ewha Womans University Medical Center were analyzed retrospectively.
A total of 35 patients with mean follow-up duration of 42 months were enrolled. At the diagnosis, 72.7% of the patients were asymptomatic, 5.7% had decompensated liver cirrhosis. The mean serum alkaline phosphate (ALP) level was 2.65 times upper limit of normal. UDCA was prescribed in 91.4% of the patients (n=32), among which 77.4% exhibited biochemical responses defined as serum ALP less than 2 upper limit of normal at 6 months (Mayo criteria).
Most PBC patients were asymptomatic at the time of diagnosis and the average biochemical responses rate to UDCA treatment were ranged from 60.0% to 78.9% according to various response criteria. To elucidate the clinical features and courses of Korean PBC patients in detail, larger scale investigations and longer clinical follow up studies are warranted.

Recently colonic mucosal lesions were reported in patients with cryptogenic liver abscess and it has been suggested that colonic mucosal break may play a role in developing liver abscess in otherwise healthy patients. We experienced a patient of severe recurrent liver abscess complicated with endophthalmitis only 3 months after successful treatment of initial cryptogenic liver abscess and a polypoid colon cancer was discovered by chance. It seems prudent to proceed colonoscopic examination in patients with cryptogenic liver abscess especially when it is recurrent.

The extent and degree of damage depends on the type and amount of substances. There are occasional reports of severe contiguous injury to the esophagus and stomach caused by strong alkali ingestion in the acute phase. Usually the deaths occur within a couple of days due to multi-organ failure after ingestion of relatively much amount of agent for a suicidal attempt. But death due to late progression is very rare.
We have reported a case of 60-year-old female patient who was diagnosed as corrosive esophagitis after accidental ingestion of strong alkali. Initial endoscopic findings were compatible with IIa-IIa-0(according to Zargar's classification) in the esophagus, stomach and duodenum, respectively. After several weeks of supportive care, her subjective symptoms were much improved during she had been wating for the operation of colon interposition due to esophageal stricture. Metabolic acidosis and thrombocytopenia developed abruptly probably due to upper gastrointestinal tract necrosis and she died when 60 days had passed after the occurrence of initial esophageal injury.

Transarterial chemoembolization(TACE)is commonly applied to the treatment of multinodular HCC in Korea and careful selection of candidate is important for the risk of various side effects. Besides common side effects as fever, nausea, abdominal pain and elevation of liver enzyme, TACE may predispose to hepatic failure, ischemic cholecystitis, pulmonary embolism, cerebral embolism and pneumonitis. In previous studies, some cases of pulmonary and cerebral embolism cases were reported but lipiodol pneumonitis after TACE was rarely reported. A 65-year-old woman with a multinodular HCC associated with HBV infection, was treated with TACE. Seven days after the procedure, nonspecific respiratory symptoms such as dyspnea and dry cough developed. Chest X-ray and chest computed tomography showed diffuse ground glass opacities in whole lung fields, suggestive of lipiodol pneumonitis. After several days of supportive care with steroid administration, radiologic abnormalities and subjective symptoms were much improved, considered that the disease was compatible with lipiodol pneumonitis.

In many cases, mixed hepatocellular-cholangiocarcinoma has been misdiagnosed as hepatocellular carcinoma or cholangiocarcinoma because of the indistinctive clinical course and radiologic findings. The clinical course and the pathologic characters are not known well, but it resembles the characteristics of hepatocellularcarcinoma rather than cholangiocarcinoma. So mixed hepatocellular-cholangiocarcinoma was classified as a kind of hepatocellular carcinoma. But the growth and dissemination rate is faster than that of hepatocellular carcinoma and the prognosis more poor. So the exact diagnosis is important. Authors experienced a patient who has the mixed hepatocellular-cholangiocarcinoma diagnosed by liver and neck node biopsy in patient who complain-ed abdominal discomfort and palpable mass, so we report the case.

, Kyu Won Chung, Jae Jung Park, Suh Eun Bae, Il Hwan Moon, Kwon Yoo, Min Sun Cho Small cell lung cancer accounts for about 20% of all lung cancers. At the time of diagnosis, the majority of patients already have metastasis. The liver is one of the most common sites of distant metastasis of lung cancer. Small cell lung cancer arises from neuroendocrine cells which produce hormone, hormone producing granules can be seen under electron microscope . A 65-year-old male was admitted to hospital because of jaundice and right upper quadrant pain. The chest roentgenogram and chest computed tomography(CT) scan showed a 3 cm mass in right upper lobe with bilateral mediastinal lymphadenopathy and right pleural effusion. The abdomen CT scan revealed multiple masses in the liver with heterogenous pattern suggesting metastatic orgin. Though the immunohistochemistry and electron miscroscopy, he was diagnosed as metastatic small cell lung cancer of liver. We report a case of the Immunohistochemical and Electron Microscopic Observation of Metastatic Small Cell Lung Cancer of Liver.
, Tae Hun Kim, Woon Sup Han Chronic HBV infection is the main cause of chronic hepatitis, liver cirrhosis and hepatocellular carcinoma in Korea. Hepatic flbrosis progresses as the duration of HBV infection prolongs therefore more advanced histologic findings are anticipated in patients with perinatally acquired HBV infection than in patients of the same age who acquired HBV otherwise. We are going to investigate the histologic findings of young adult patients with chronic hepatitis B with respect to maternal HBsAg status, duration of HBV possession and senun HBeAg starus and ALf levels.
A total of 96 HBsAg positive young adult male patients who visited our hospital forliver biopsy were enrolled and their histologic findings were analysed according to the standardcriteria. The medical records of the patients were reviewed and supplementary information weretaken via telephone interviews.
Hepatic inflammatory scores and fibrosis stages were increased as the serum ALf level increased. Histologic findings showed no significant differences according to the duration of HBV infection, serostatus of HBeAg, the number of HBsAg positive cells and matemal senun HBsAg status.
In young adult patients with chronic hepatitis 3, the hepatic histologic findings were worsen as the serum ALf level increased and associated with neither the HBeAg status of the patient nor the matemal HBsAg status.

The aim of this study was an evaluation for the clinicopathologic characteristics of rectosigmoid adenomas on preoperative sigmoidoscopy in gynecologic cancer patients.
A total 187 gynecologic cancer patients(139 cervical, 35 ovarian, 13 endometrial cancer) and 58 normal controls were reviewed sigmoidscopic finding and pathologic reports retrospectively from September 1993 to March 2001.
The mean age of gynecologic cancer patients was 54(38-82) year-old and normal controls was 50(20-68) year-old. Total 26 adenomas were in 21 patients(11.2%) and 3 adenomas were in 3 normal controls(5.2%). The incidence of adenomas was 9.4% in cervical cancer, 8.6% in ovarian cancer and 38.5% in endometrial cancer. Multiple adenomas were in 5 gynecologic cancer patients and 0 normal controls. The incidence of advanced adenoma was 12.5% in cervical cancer, 25.5% in ovarian cancer, 83.5% in endometrial cancer and 33.3% in normal controls. The location of adenoma was 23.1% in rectum and 76.9% in sigmoid colon.
The incidence of adenomas and multiple adenomas were higher in gynecologic cancer patients than normal controls but not significantly. The incidence of advanced adenoma and adenomas were significantly higher in endometrial cancer than normal controls. Colonoscopic evaluation of whole colon will be recommanded in gynecologic cancer than sigmoidoscopy.
, Sun Young Yi, Sung Ae Jung, Kwon Yoo Magnetic resonance cholangiography(MRC) has emerged as an accurate and noninvasive modality for the evaluation of the biliary diseases. We performed this study to access the accuracy and efficacy of MRC for the diagnosis of obstructive biliary diseases.
From March 1999 to September 2000, 87 patients with obstructive biliary diseases(24 malignant cancers, 55 cholelithiasis, 8 other obstructive biliary diseases) underwent MRC.
MRC correctly revealed the obstructing biliary lesions and the cause of obstructions in 100% and 92% of the cases of malignancy respectively. The sensitivity and specificity of MRC were 94%, and 82% for extrahepatic bile duct stones, 94%, 100% for intrahepatic bile duct stones, and 84%, 100% for gallbladder stones retrospectively. In the other cause of biliary obstructions(3 benign biliary stricture, 2 acalculous cholecystitis, 2 xanthogranulomatous cho-lecystitis, and 1 extrinsic compression due to lymphadenopathy), MRC correctly showed the level of obstructions in all patients. But, MRC could not diagnose accurate causes of the obstruction except 3 patients(1 acalculous cholecystitis, 1 xanthogranulomatous cholecystitis, and 1 extrinsic compression due to lymphadenopathy).
This study demonstrated that MRC was able to accurately identify the level and the cause of biliary obstructions in both malignancy and cholelithiasis. MRC was easily performed for a short duration and was a noninvasive diagnostic modality for assessing the biliary tree. Therefore, MRC was very efficacious clinically for the diagnosis of obstructive biliary diseases.
, Sung Ae Jung, Min A Yu, Young Ju Choi, Ji Yoon Cho, Su Hyun Kim, Kwon Yoo, Il-Hwan Moon The aim of this study was to evaluate the clinicopathologic characteristics of the colorectal polyps in people under 50 years old.
From January to August 2001, the colonoscopic finding and pathologic reports of 527 patients under 50 years old who underwent colonoscopy were reviewed retrospectively. The advanced polyp was defined as an adenoma more than 10mm in diameter or with the histology of villous or high grade dysplasia.
Total 94 colonic polyps(17.8%) were analyzed. On age distribution, 65 cases(69.1%) were in forth decade, 25 cases(26.6%) in third decade. Abdominal pain(29.8%) was the most common cause of taking the colonoscopic examination followed by rectal bleeding(18.1%), asymptomatic screening(12.7%). Rectosigmoid area was the most common site of polyps in 63.8%. On the pathologic review, adenoma was found 55.1%, inflammatory polyp 38.5% and hyperplastic polyp 6.4%. Advanced adenomas were 17.9%(17/156) and adenomas with focal carcinomatous changes were 1.9%(3/156). Patients who had symptoms of abdominal pain or rectal bleeding, multiple polyps or familial history of colorectal cancer had a higher prevalence of advanced adenoma than that of non-advanced adenoma(
This study showed that major symptoms of patients with advanced polyps under 50 years old were abdominal pain and rectal bleeding. The symptoms, multiplicity of polyp and family history were important indicator of advanced polyps. Further study was needed for reasonable indication and cost effectiveness for colonoscopic examination in young age people.
