Carcinoma of the gallbladder is relatively rare malignancy usually found in an elderly, predominantly female population. Histologically, adenocarcinoma predominate, with only 10% to 15% being of other varieties(small cell carcinoma and others). Small cell carcinoma of the gallbladder is a rare lesion and predominantly a disease of older women with clinical history of stones. These tumors show an aggressive clinical course and death usually occurs with in a few months of the diagnosis. The diagnosis of small cell carcinoma should be based on cell morphology, histologic pattern and immunohistochemical study. Correct diagnosis is important not only because these tumors give rise to endocrine syndromes, but also because the chemotherapeutic approach to small cell carcinoma differs from that for adenocarcinoma.

OBJECTIVES: Aeromonas species is a gram-negative, facultative anaerobe of the family Vibrionaceae. The organism has been recognized as a pathogen associated with illness in human, such as acute gastroenteritis, cellulitis, septicemia, and other rare diseases. METHODS: To evaluate the clinical significance of Aeromonas bacteremia in Korea and it's susceptibility of antibiotics, we evaluated the 17patients with Aeromonas bacteremia. Identification was done by use of API 20E system and antibiotic susceptibility was tested with disk diffusion method. RESULTS: Male to female ratio was 11:6, and mean age was 54.1years(8-85years) old. Liver cirrhosis was the most common underlying disease(10cases of 17patients, 58.8%a). Other underlying diseases were as follows: gallstone in 2cases, cholangiocarcinoma in 2cases, and aplastic anemia in 1case, cerebral infarction in 1case. But one had no underlying disease. So Aeromonas bacteremia were occurred in 14immunocompromised patients(82.3%), and in 10patients with hepatobiliary diseases, A. hydrophila was most commonly isolated(13cases, 764%), and the A sobria(4cases, 23.5%) was infrequently isolated. The overall fatality was 47%, and there had no significant difference in fatality between A. hydrophila and A sobria All Aeromonas species had resistance to ampicillin and carbenicillin. CONCLUSION: Because Aeromonas bacteremia may occur through water-borne route, especially in immunocompromised host. We should pay attention to immunocompromised patients, espacially having hepatobiliary disease.

Acute pancreatitis due to impaction of Ascaris lumbricoides into the pancreatic duct is very rare. Authors hnve experienced one case of pancreatic ascariasis. Patient was a 62-year-old female with epigastric pain. Abdominal USG and endoscopic retrograde cholangiopancreatography showed characteristic finding of pancreatic ascariasis. Ascaris was removed with palypectomy snare and acute pancreatitis was resolved completely.

OBJECTIVE: This study was undertaken to document current practice patterns for the surgical treatment of endometrial cancer in Korea. METHODS: Questionnaires were distributed to 131 Korean gynecologic oncologists, all members of the Korean Gynecologic Oncology Group. Questions addressed extent of hysterectomy procedure, pelvic (PEN) or paraaortic (PAN) lymph node dissection, ovarian preservation, and omentectomy. RESULTS: Completed questionnaires were returned by 64.1% (84/131) of the oncologists at 50 institutes. Extrafascial hysterectomy (EH) was used by 32% of respondents and modified radical hysterectomy (MRH) or radical hysterectomy (RH) by 17%. Hysterectomy procedures were selectively employed based on tumor-related factors by 51% of the respondents. Laparoscopic hysterectomy was routinely utilized by 49% and was more commonly used by younger surgeons with 10 years of experience or less. PEN dissection was routinely utilized by 67% and was used selectively based on tumor-related factors by 33%. PAN dissection/biopsy was used either routinely (43%) or selectively based on tumor-related factors (43%). PAN dissection/biopsy had never been employed by 12% of the respondents. Sixty-nine percent of respondents stated that grossly normal looking ovaries can be preserved during surgery in young aged patients with early stage disease, and 29% stated that bilateral oophorectomy should be performed irrespective of age or stage. Omentectomy was routinely performed by 11% of respondents, and was selectively performed when extrauterine spread was present by 41%. CONCLUSION: Surgical procedures for the treatment of endometrial cancer are still not standardized among Korean gynecologic surgeons. Clinical trials to determine the benefits of the different surgical procedures should be developed.

OBJECTIVE: Regarding vulvar cancer, a nomogram has been suggested for the prediction of relapse-free survival (RFS). While the nomogram has been developed and validated in a Western study, there was no validation in Korean population. Thus, we have undertaken the study to assess the applicability of nomogram for predicting RFS in Korean patients with vulvar cancer. METHODS: A total of 204 cases newly diagnosed as vulvar cancer between 1982 and 2006 were identified. Among them 70 cases were not eligible due to inappropriate cell type (40 cases) and radiation as primary therapy (30 cases). Forty-four cases were not evaluable due to inadequate data and persistent disease. Finally a total of 90 patients primarily treated by surgery were included for analysis. Variables including age and the characteristics of primary tumor, nodal status, and surgical margin were collected for predicting RFS based on nomogram, which was compared with actual RFS. A calibration plot was drawn showing the actual versus predicted probability for 6 groups of patients segregated according to their predicted probabilities. In addition, discrimination of the nomogram was quantified with the concordance index. RESULTS: Patients' mean age was 58 years and mean follow-up period was 47.9 months. Observed 2y- and 5y-RFS rates were 81% and 68%, respectively, corresponding to 79% and 72% in the original cohort. The trend line in calibration plot showed comparable concordance with an ideal line, having a slope of 1.04 for 2y-RFS (R(2)=.35) and 0.98 for 5y-RFS (R2=.80), respectively. The concordance index was 0.79 in the KGOG data set, which was improved to 0.82 with the data set limited to squamous cell carcinoma. CONCLUSION: The nomogram provides the predictive capacity for relapse-free survival in Korean patients with vulvar cancer.

Idiopathic segmental ileal dilatation is a rare congenital condition in which the caliber of the bowel lumen increases locally without distal luminal obstruction or thickening of the muscle coats in involved lumen. Congenital abnormalities such as exomphalos, malrotation of the midgut, and Meckel's diverticulum are found frequently in the patients with segmental dilatation of the small bowel. Intermittent abdominal pain or anemia may be the symptoms of segmental dilatation of the small bowel in infants, children and occasionally adults. The radiologic finding in barium studies of the small bowel is characteristic axial segmental dilatation. The pathologic finding is nonspecific ulcer and mild congestion, but it has normal nervous system and smooth muscle bundle. There are no evidence of ischemic changes, inflammatory changes or neoplastic changes. The condition can be cured with surgical excision of the dilated segment. A case of idiopathic segmental ileal dilatation associated with melena and recurrent abdominal pain diagnosed by enteroclysis in a 47 years old man was presented with brief review of the literature.

Xanthogranulomatous cholecystitis is a rare form of chronic gallbladder inflammation that is characterized by a severe proliferative fibrosis and has rarely been described in the radiologic literature. Like xanthogranulomatous pyelonephritis, it is an entirely benign but unusual expression of a reactive process and may be confused with a malignant neoplasm. Histologically, foamy histiocytes, multinucleated giant cells, other inflammatory cells, fibrous reaction with spindle cells, cholesterol cleft and noncaseating granuloma were found. Treatment of this benign inflammatory condition requires cholecystectomy to remove the focus of inflammation, control subsequent infection and relieve symptoms A case of xanthogranulomatous cholecystitis mimiking carcinoma of the gallbladder on abdominal USG, abdominal CT, and ERCP examination is presented with brief review of the literature.
