Although acute acalculous cholecystitis (AAC) accounts for less than 10% of acute cholecystitis in the adult population, gangrene and perforation are much more frequent compared to the usual cases of acute cholecystitis (calculus cholecystitis). However, spontaneous biliary-enteric fistula is well recognized in AAC, 90% of which are cholecystoduodenal fistula (CDF) though it is an uncommon disorder. The majority of the CDF are caused by cholelithiasis. As patients are usually associated with complicated clinical illness, the diagnosis is often difficult to make and required surgery is often delayed. We have studied a rare complication of acute acalculous cholecystitis which was presented as intermittent upper gastrointestinal bleeding. Ulceration of the superficial branch of the cystic artery has been observed due to acalculous cholecystitis associated with a cholecystoduodenal fistula. We have performed a transfixing ligation of the bleeding vessel, cholecystectomy and simple closure of the CDF. We have finally made a diagnosis of early gallbladder cancer through a frozen section. There was no serious complication after the operation and the patient has achieved an uneventful recovery.

BACKGROUND: Perfusion scans are accurate predictors of postoperative lung function. There are few previous studies aimed at predicting the postoperative exercise capacity using the perfusion scanning and those that did reported contradictory results. METHOD: We prospectively studied the preoperative spirometric, exercise tests and perfusion scans from in 49 consecutive patients who were admitted to Inha University Hospital with surgically resectable lung cancer from Jan. 1998 to Jun. 1999 29 patients who had any condition affecting the lung function and exercise capacity, or refused a surgical resection or a follow-up study were excluded. Spirometric and exercise tests were performed 6 months after operation in 20 patients. RESULTS: The predicted postoperative FEV1, FVC and TLC correlated well with the following corresponding postoperative values : γs and p value, 0.809 and 0.000 for the FEV1 ; 0.895 and 0.000 for the FVC ; 0.741 and 0.006 for the TLC, respectively. The measured postoperative exercise values were slightly higher than the postoperative exercise values predicted, VO(2max) and Wr(max), were as 112% of VO(2max) predicted and 119% of WR(max) predicted. The change in FEV1, FVC and TLC had a weak correlation with the change in VO(2max) and WR(max). CONCLUSION: The perfusion scan was a useful tool for predicting the postoperative exercise capacity. However, they had a tendency to underestimate the exercise capacity, especially in the patients who had a pneumonectomy. A weak correlation between the change in lung function and exercise capacity was obseved.

Social networks are useful in the study of relationships between individuals or entire populations, and the ties through which any given social unit connects. Those represent the convergence of the various social contacts of that unit. Consequently, the term "social networking service" (SNS) became extremely familiar. Similar to familiar SNSs, International Digestive Endoscopy Network (IDEN) 2014 was based on an international network composed of an impressive 2-day scientific program dealing with a variety of topics for gastrointestinal (GI) diseases, which connects physicians and researchers from all over the world. The scientific programs included live endoscopic demonstrations and provided cutting-edge information and practice tips as well as the latest advances concerning upper GI, lower GI, and pancreatobiliary endoscopy. IDEN 2014 featured American Society for Gastrointestinal Endoscopy-Korean Society of Gastrointestinal Endoscopy (ASGE-KSGE)-joint sessions prepared through cooperation between ASGE and KSGE. Furthermore, IDEN 2014 provided a special program for young scientists called the 'Asian Young Endoscopist Award Forum' to foster networks, with many young endoscopists from Asian countries taking an active interest and participation.

Background: Data on the relationship between Parkinson's disease (PD) and stroke have been conflicting, some studies showing a reduced risk of stroke during life because of low prevalence of vascular risk factors, and others indicating an increased risk of strokerelated death. The objective of this study is to determine the frequency of vascular risk factors in PD in relation to an unaffected control group and ischemic stroke patient group. Methods: We performed a case-control study on 206 consecutive PD patients, 207 ischemic strokes patients (served as "Disease" controls) and 138 age and sex matched normal subjects (served as controls), calculating multivariate risk estimates (odd ratio) for a series of established risk factors for vascular disease. Results: We found that (1) cigarette smoking (smoker, 0.078, CI=0.034-0.178; ex-smoker, 0.031, CI=0.011-0.088), and diabetes mellitus (0.340, CI=0.169-0.682) were significant less frequent in PD patients than controls, (2) cigarette smoking (smoker, 0.230, CI= 0.094-0.561; ex-smoker, 0.132, CI=0.050-0.348), hypertension (0.283, CI=0.175-0.459), diabetes mellitus (0.257, CI=0.136-0.486), previous stroke (0.063, CI=0.020-0.191), heart disease (0.344, CI=0.176-0.673) than ischemic stroke patients, respectively. Conclusion: We found the significant negative association of a series of vascular factors with PD, indicating a protective effect of PD against ischemic stroke.

Clinical Endoscopy (CE) is an official open access journal published bimonthly by the Korean Society of Gastrointestinal Endoscopy (KSGE, http://www.gie.or.kr) and is listed on PMC, PubMed and SCOPUS. The KSGE was established on August 14, 1976, and the journal of the KSGE was published in Korean for the first time in November 1981. The journal was then titled the "Korean Journal of Gastrointestinal Endoscopy" and was published in Korean untill the July 2011 issue. The journal was published in English from the September 2011 issue under the official title of CE. In this review, the past and present of CE are discussed and future perspectives are introduced. In addition, the efforts to progress to a "first come, first served journal" in the field of gastrointestinal endoscopy and to be indexed in Science Citation Index will be described.

Sparganosis is a parasitic infectious disease by sparganum which is a plerocercoid larva of spirometra, a kind of cestode. We experienced a case of intramural sparganosis of cecum presenting as chronic intermittent abdominal pain. A 39 year old man was hospitalized due to intermittent abdominal pain for 6 months and the operation was done under the impreesion of the intestinal tuberculosis or submucosal tumor of cecum after diagnostic work-up. Resected cecum revealed diffuse wall thickening and luminal narrowing. The microscopic findings showed a degenerated larva in the muscle layer with typical tissue reaction which was basically noncaseating cavitary granulomatous inflammation and many calcareous corpuscles which were pathognomonic features of cestode were prominent within the degenerated worm.
