The electrocardiogram (ECG) and electrolytes were measured to obtain diagnostic data after experimental obstruction of duodenum in 8 dogs. Clinical signs of these appeared lower heart rate, temperatures respiration and blood pressure than signs of preoperation. In changes of electrolytes and acid-base balances, all dogs appeared hyponatremiai hypochloremia, metabolic alkalosis, and increased pHi HCO3, scot in blood, but potassium values appeared to increase in 3 cases fl-inc.) and to decrease in 5 cases (K- dec.) Two of three in K-inc. and three of five in K-dec. died at 60 hrs and 72 hrs after obstruction respectly. In changes of ECGI amplitudes of the K-inc cases appeared high in T wave and low in R wave, but amplitudes of the K-dec cases appeared low T waver 57 segment and high in R wave. Conduction times of the K-inc appeared the shorted PR intervals but the K-dec appeared the prolonged PR interval. The changes of these appeared apparently in lead II.

Purpose: With the introduction of H. pylori eradication and proton pump inhibitor, the operative treatments for the acute or chronic complications of peptic ulcer, such as perforation, bleeding and stricture, have decreased. Also owing to the development of non-operative treatment such as interventional endoscopic treatment, the surgical approach to the acute complications, like perforation and bleeding, has diminished. The non-operative treatments for the stricture and obstruction of chronic peptic ulcer in part related to discontinuation of medication have not been satisfactory. We analyzed the clinical outcomes of the patients who underwent operative treatment for outlet obstruction with peptic ulcer. Materials of Methods: From January 1994 to December 2007, we reviewed 31 patients who had been operated on at the National Medical Center for peptic ulcer obstruction. We excluded the cases of adhesive obstructions that were caused by a former ulcer operation and also the cases of obstructions found during emergency operations for treating perforation and bleeding. We classified the surgical treatment group into the bypass operation group and the surgical resection group. We evaluated the effects of the operations by the Visick score. The recurrences were confirmed only by the endoscopic observation of peptic ulcer. Results: The number of patients in the bypass operation group was 6 (19.4%) and that of resection group was 25 (80.6%). The mean age was 57.5 (25~81) years. The number of male patients was 29 (93.5%) and the number of females was 2 (6.5%). The mean symptom duration was 29.6 months. There were 19 smokers (61.3%), 6 NSAID users (19.4%) and 7 H. pylori positive patients (22.6%). Two patients underwent endoscopic balloon dilatation with no success. The locations of lesion were the stomach, the duodenum and both in 9, 20 and 2 cases, respectively. There were operative complications in 13 cases (41.9%), recurrent ulcers in 2 cases (6.5%), and reoperations in 4 cases. The mean Visick score was 1.8 (1~4). There were no statistically significant clinicopathologic differences between the bypass operation group and the resection group. The two groups had 1 case each of recurrence. Although the bypass group had a greater complication rate (83.3%) than the resection group (32%), this was not statistically meaningful (P=0.175). The mean Visick score was 3.0 in the bypass group and 1.6 in the resection group, so the resection group was better (P=0.001). Conclusion: For a case of chronic peptic ulcer with outlet obstruction, even though it has been reported that endoscopic balloon dilatation worked well, surgery is still regarded as an important treatment. If you consider the patients' satisfaction and the difficulty of diagnosing malignant ulcers, surgical resection should be recommended more often than a bypass operation.

Purpose: The aim of this study is to investigate the usefulness of intestinal ultrasonography (US) and upper gastrointestinal endoscopy in the early diagnosis of Henoch-Sch$\"{o}$nlein purpura (HSP) with the gastrointestinal (GI) symptoms preceding the emergence of the skin lesion. Methods: The clinical, intestinal US and upper gastrointestinal endoscopic records of 85 patients (88 cases) with GI symptoms relating to HSP presenting between January 1999 and April 2001 were reviewed. Results: 1) GI symptoms were observed in 52 cases (59%) and skin, joint, renal and scrotal manifestations were observed in 88 (100%), 64 (73%), 15 (17%), 3 cases (3%) respectively. 2) Out of 52 cases with GI symptoms, abdominal pain was observed in all cases (100%). Positive stool occult blood, nausea and vomiting, abdominal tenderness, melena or tarry stool, diarrhea, hematemesis, rebound tenderness and rigidity were observed in 28 (50%), 17 (33%), 17 (33%), 12 (23%), 6 (12%), 4 (8%), 1 (2%) and 1 case (2%) respectively in order of frequency. 3) Intestinal US examination was performed in 27 cases with HSP and GI symptoms (52 cases). Out of 27 sonographic examinations 22 showed abnormal findings. Thickening of the duodeno-jejunal wall was observed in 16 cases (73%). Free peritoneal fluid, enlarged mesenteric lymph node, ileus and abnormal gall bladder were seen in 8 (36%), 8 (36%), 4 (18%) and 1 case (5%) respectively. In three cases of HSP without GI symptoms, those changes were absent. 4) In all of five cases with HSP and GI symptoms, endoscopic study showed mucosal edema and multiple hemorrhagic erosions especially at the second portion of the duodenum. Biopsy specimens from the duodenum of 2 cases out of 5 endoscopic examinations showed acute inflammatory infiltrates in the mucosa with hemorrhage. 5) Both intestinal US and endoscopic studies were performed in 4 cases with HSP and GI symptoms simultaneously. Out of 4 those cases, 3 cases showed the thickened duodeno-jejunal wall on the intestinal US, which suggested erosive hemorrhagic duodenitis by endoscopic findings. Conclusion: The typical but nonpathognomonic intestinal US findings including the thickening of the duodeno-jejunal wall and upper gastrointestinal endoscopic findings including hemorrhagicerosive duodenitis, in children with GI symptoms, should be considered a manifestation of HSP, even in the absence of skin lesion.

From the one hundred forty eight patients with evidence of biliary tract obstruction, 275 bile samples were obtained from percutaneously placed biliary drainage catheters. Of the 148 patients, ova of Clonorchis sinensis were demonstrated in 17 patients (11.5%), with the epithelial cells. Among them, one case also demonstrated coexisting adenocarcinoma. In 105 patients, the medical records were available for review and the clinical diagnoses were malignancy in 99 patients and benign lesion in 6 patients. Of the 99 patients in which clinico-radiologic diagnosis were malignant, cytologic results were positive in 23.2%. Dividing the patients Into two groups, the ones with tumor of bile duct origin (group I) and the others with tumors producing extrinsic compression of bile duct, such as periampullary carcinoma, pancreas head carcinoma or metastatic carcinoma in lymph nodes from tumors of adjacent organs (group II), the cytologic results were positive in 37% and 11.6%, respectively. In patients with histologic confirmation, the positive correlation was found in 50% and 20% in group I and group II, respectively, with remarkable difference between two groups. There were no false positives in cytologic diangosis. The overall concordance rate of cytologic diagnosis with diagnosis of clinical investigation in both benign and malignant lesions was 27.6% and the diagnostic specificity was 100%.
