    ABSTRACT: Common bile duct (CBD) stone is a relatively common disease in elderly patients. There have been many reports about the efficacy and safety of LCBDE. But for elderly patients, only a few studies about its efficacy and safety exist. The aim of this study is to evaluate the efficacy, safety and the surgical outcome of LCBDE in patients who are 70 years or older and compare the results with those of the younger group. From January 2000 to November 2009, 132 patients underwent LCBDE. We divided these patients into two groups according to age and conducted a retrospective analysis. The elderly group included patients who were 70 years old or older (n = 64), and the younger group included those who were younger than 70 (n = 68). The elderly group was compared to the younger group with respect to their clinical characteristics, operation time, postoperative hospital stay, open conversion rate, first meal time, postoperative complication, recurrence rate and mortality. The elderly group showed high American Society of Anesthesiologists score (2.2 vs. 1.9) (P = 0.003), preoperative morbidity (47 vs. 29) (P < 0.001), and previous abdominal operation (18 vs. 14) (P = 0.046). There were no significant differences in mean operation time, postoperative hospital stay, first meal time, recurrence rate, remnant stone, complication rates or mortality in both groups (P > 0.05). LCDBE is a safe and effective treatment modality for CBD stones not only for younger patients but also for elderly patients.

    ABSTRACT: Purpose: Laparoscopic cholecystectomy (LC) for asymptomatic gallbladder disease has been increasing since 1990 due to the development of LC technique. Moreover, it might be considered when someone with asymptomatic gallbladder disease needs emergency operation due to acute abdomen such as acute appendicitis. The aim of this study is to identify the efficacy of concurrent laparoscopic appendectomy with cholecystectomy. Methods: From January 1997 to June 2009, 40 patients underwent laparoscopic appendectomy with cholecystectomy at Ewha Womans University Mokdong Hospital. 40 patients were enrolled in this study. We analyzed, retrospectively, clinical and diagnostic information, time and open conversion rate in operation, length of postoperation hospital stay, and complication rate. Results: The mean age was 44.53 +/- 15.34 and male to female ratio was 1 to 1.86. 5% of all patients underwent abdominal surgery and 20% of all patients had associated diseases. Most common associated symptoms and final diagnosis were right lower abdominal pain (72.5%) and simple gallbladder stone (62.5%). Mean operation time was 98.75 +/- 33.14 min. and there was no open conversion. Mean length of postoperation hospital stay was 5 2 days. There was one (2.5%) postoperative complication. Conclusion: Combined operation of laparoscopic cholecystectomy during laparoscopic appendectomy can be a good modality for patients with chronic gallbladder disease.

    ABSTRACT: Several clinical risk factors for low bone mineral density (BMD) in the patients with inflammatory bowel disease (IBD) have been suggested. However, its prevalence and pathophysiology in Korean population have not been fully studied. The aim of this study was to investigate the prevalence and risk factors for low BMD in Korean IBD patient. BMD of the lumbar spine and femur was evaluated using dual-energy X-ray absorptiometry in 30 patients with IBD. Biochemical parameters of bone metabolism, such as serum calcium, phosphorus, osteocalcin, and deoxypyridinoline were measured. The associations between low BMD and clinical parameters such as disease duration, disease activity, drug history, body mass index (BMI), and others were evaluated retrospectively using medical records. Low BMD at the lumbar spine or femur was observed in 63.3% of the patients, and there was no significant difference between the patients with Crohns disease and ulcerative colitis. Clinical and biochemical parameters were irrelevant to BMD. In the patients without glucocorticoid treatment prior to BMD measurement, already 50.0% of patients had low BMD. Low BMD is a common feature in Korean IBD patients, even those who do not use glucocorticoid. The multiple factors may be involved in the pathogenesis of low BMD. Therefore, BMD should be examined in all IBD patients, irrespective of glucocorticoid treatment.

    ABSTRACT: Mixed hepatocellular-cholangiocarcinoma accounts for about 1% of all hepatocellular carcinoma. 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.

    ABSTRACT: 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.

    ABSTRACT: Nowadays, upper gastrointestinal endoscopy is very commonly performed procedure as a diagnostic tool or therapeutic purpose. Although perforation rate during diagnostic evaluation has been reported as low about 0.03%, gastrointestinal perforation is a critical problem to the patients owing to significant morbidity and hospital stay. Therefore, all endoscopists should know the risk factors for the perforation and pay attention to avoid this complication. We experienced a case of 66 year-old-male with duodenal microperforation after endoscopic biopsy. During endoscopic examination, a submucosal mass was detected at duodenal second portion and endoscopic biopsy was performed. After this, he complained of severe abdominal pain during colonoscopy. Emergent simple abdomen and abdominal computed tomography revealed multiple free air in retroperitoneal space and duodenal perforation was suspicious. He was treated with primary closure and then recovered completely. Therefore, we report a case with microperforation after endoscopic duodenal biopsy.

    ABSTRACT: Small cell lung cancer is characterized by an aggressive clinical course and a high tendency for early dissemination in spite of a good chemotherapy response. Topotecan is a topoisomerase I inhibitor, and it is used as second-line treatment for small cell lung cancer. The reported dose-limiting adverse reactions to topotecan are mainly hematologic. Yet pulmonary toxicity associated with topotecan is known to be rare. We report here on a case that showed the development of acute respiratory distress syndrome during the 3rd cycle of topotecan chemotherapy in a patient with small cell lung cancer. He developed dyspnea and respiratory failure, and the chest CT scan revealed diffuse ground-glass opacity that was probably due to chemotherapy-related pulmonary toxicity. He finally died of acute respiratory distress syndrome.
