Gastric bezoars are large masses or concretions, composed with plant fiber, hair and miscellaneous foreign bodies, found in the stomach and occur usually as sequele of gastric surgery. We experienced 2 cases of fat bezoars which developed after drinking of melted beef fst. They had postprandial epigastric fullness and pain, those were relieved on supine and left recumbent position. Upper gastrointestinal series showed a large movable mass in the stomach in hoth cases. On gastrofibercopic examination, a large egg sized white bezoar was cordirmed in both cases and a gastrie ulcer at antrum associated in one case. In attempt to removal of the bezoars, we tried to break them, but failed because of its character. The patients were treated with pancreatic lipase containg digestives, Pancreon-F and Azintal. From one day after this treatment, symptoms were completely relieved. Five days later, we confirmed disappearance of bezoars by gastrofiberscopy. and upper gastrointestinal barium

: In order to know the species and frequency of human parasitic infection diagnosed by biopsy, 149 cases (0.18%) of parasitic infection were reviwed, which were selected from 80,947 biopsied materials submitted for routine histopathological examination during a period of 10 years from 1980 to 1989 at Department of Pathology, Chonnam National University Hospital. They consisted of 112 cases of cysticercosis, 17 paragonimiasis, 7 clonorchiasis, 4 amebiasis, 1 sparganosis, 1 enterbiasis, 1 aniskiasis, and 1 fascioliasis respectively. Based on morphological preservation of cysticercus, they could be divided into mild (20.2%), morderate (40.4%), and severe (39.4%) degeneration. Except 2 cases biopsied at the lungs, 15 cases of ectopic paragonimiasis were located at abdominal cavity (8 cases) and central nervous system (7 cases). One case of intrahepatic fascioliasis was observed. This is the 13th human fascioliasis reported in Korea. From the above results, the frequency of parasitic infections found in biopsied specimens was on the decrease as the cysticercosis and ectopic paragonimiasis.

PURPOSE: To compare the detectability and conspicuity of focal hepatic lesions among conventional spin echo techniqueniques and fast scanning techniqueniques in MR imaging. MATERIALS AND METHOD: 36 patients (24 men and 12 women, mean age of 54 years) with suspected liver mass on CT scan and US underwent MR imaging at 1.5 T system. Conventional spin echo T1, T2 weighted imaging, T2 weighted fast spin echo, T1 weighted fast multiplanar spoiled gradient recalled(FMPSPGR) imaging and Gd-enhanced FMPSPGR(Gd-FMPSPGR) were performed. 16 cases of hepatocellular carcinoma, 13 cases of hemangioma, 3 cases of metastasis, 3 cases of cholangiocarcinoma, and 1 case of lymphoma were included. Lesion conspicuity and number of detected hepatic masses were compared among the MR sequences. RESULTS: Overall 63 hepatic lesions were detected in 36 patients. Lesion detection' was 63(100%) with Gd-FMPSPGR, 62(98%) with non-enhanced FMPSPGR, 58(92%) with SE T2WI, 56(89%) with SE T1WI and 54 (86%)with FSE. For solid tumors, the contrast to noise ratio was greatest on Gd-FMPSPGR which was significantly higher than any other sequences. For hemangiomas it was greatest on SE T2WI and was significantly higher than SE T1WI. In the qualitative assessment, Gd-FMPSPGR was preferred for both solid mass lesion and hemangioma. FSE was inferior to SE T2WI for lesion detection and conspicuity without statistical significance. CONCLUSIONS: For the evaluation of focal hepatic lesions, breath-hold FMPSPGR with and without contrast enhancement may replace the conventional SE T1WI. Because FSE was inferior to SE T2WI when the later is used with respiratory compensation in some cases, it is difficult to replace the SE T2WI with FSE. But FSE, FMPSPGR and Gd-FMPSPGR images, when combined, may replace SE T1WI and SE T2WI.

During a 12-month period high-resolution, real-time ultrasonography (US) with graded compression was performed on 268 consecutive patients with clinically suspected acute appendicitis and its complication. US visualization of a fluid-filled, non-compressed appendix or a decompressed, thick-walled appendix was the primary criterion for a diagnosis of acute appendicitis. The sonographic findings were correlated with surgical-pathologic outcome in 92 cases and with the findings of clinical follow-up in the remainder. US was found to be accurate in the diagnosis of acute appendicitis and its complication with a sensitivity of 93.3%, a specificity of 98.9%, and an accuracy of 97%. The predictive value of a positive test was 97.7%; that of a negative test was 96.7%. There were two false-positive examination in patients with a thick-walled appendix or periapperdiceal abscess, which were surgically confirmed as appendiceal adenocarcinoma and perforated cecal diverticulitis respectively. There were six false-negative examination in patients with a sonographically no-visible appendix, which were confirmed surgically as acute appendicitis(n=5) and perforated appendicitis(n=1). Our results show that high-resolution, real-time US is an accureate imaging modality in the diagnosis of acute appendicitis and the evaluation of its complication.

The occurrence of the colonic obstruction secondary to colorectal carcinoma (CRC) has been reported in 7~30% of the CRC patients. It is generally believed that obstructive CRC is associated with a poor prognosis with respect to operative mortality and five-year survival. A series of 1064 cases of the CRC treated surgically at Asan Medical Center from June 1989 to December 1996 has been analyzed to compare clinicopathological findings between obstructive and non-obstructive CRC and to evaluate surgical treatment options in obstructive CRC. Complete obstruction was present in 49 cases (4.6%). There were no differences between obstructive and non-obstructive CRC in tumor location, size, Dukes' stage, and differentiation. In forty-nine obstructive CRC cases, primary resections were performed in 29 cases after peri-operative bowel decompression. In this group, right colon cancer was more prevalent than staged operation group (45% vs. 5%, P<0.05) and hospital stay was significantly short (16 days vs. 38 days, P<0.05). Postoperative complication rate was higher in staged operation group (65% vs. 28%, P=0.01). It may be due to stoma related wound complication. In obstructive left colon cancer, there was a significant difference in complication rate between primary resection and staged operation (P<0.05). Overall 5-year survival rate were 66% and 53% in non-obstructive and obstructive group, respectively. Survival rate according to the Dukes' B and C stages did not show statistical differences, either. Conclusively, primary resection is preferred to the obstructive CRC when supportive care, preoperative bowel decompression, and intraoperative colonic irrigation were performed adequately.

This case report describes a patient with semipedunclated granuylar cell tumor(granular cell myoblastoma) of the proximal ascending colon removed by endoscopic polypectomy. A 39-year old femalie was visited to our hospital for intermittent abdominal pain and loose stool. Colonoscopic examination showed a semipedunclated lesion covered with yellowish white smooth mucosa in the proximal ascending colon. The tumor was removed by endoscopic polypectomy. The collected specimen was 0.9x0.8 cm in size. The cut surface of the specimen showed a white round firm tumor covered with mormal epithelium of the colon. Using immunohistochemical study, the tumor cells were to be positively stained by S-100 protein and negatively stained by desmin, which supports the concept of the Schwann cell origin of granular cell tumor. In Korea, 2 cases of granular cell tumor of the colon and rectum, which were treated by surgical removal, have been reported. This case in the first endoscopic polypectomy of granular cell tumor of the colon and retum in Korea. The endoscopic polypectomy is thought to be useful for the therapy of small pedunclated or semipedunclated granular cell tumor, intracolonic type.
