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.

BACKGROUND/AIM: Serial measurement of serum carcinoembryonic antigen was assessed to define its significance and to determine the adequacy in detecting recurrence after curative resection for colorectal cancer. METHODS: Six hundred forty-five patients with colorectal cancer underwent curative resection were included. The median follow-up period was 49 months (range, 24~94 months). Serum CEA was analyzed in accordance with location, histologic differentiation, stage of the tumor, recurrence and survival. RESULTS: The incidence of elevated preoperative serum CEA (> 6 ng/ml) was correlated with tumor stage (stage I vs. II, P=0.01; stage II vs. III, P=0.0001). Fifty five patients among 87 patients with recurrence (63.2%) had concomitant elevation of serum CEA, whereas 32 of 558 patients (5.7%) without recurrence showed a false-positive result. Measurement of serum CEA was more sensitive in patients with elevated preoperative serum CEA and liver metastases than in patients without elevated preoperative serum CEA and local recurrence (P=0.0397). The leading time of serum CEA between the first elevated serum CEA and the identification of recurrence was 3.5 months (range, 1~12 month). Tumor stage and preoperative serum CEA level were found to be significant prognostic variables by multivariate analysis. The overall 5-year survival rate in the normal preoperative serum CEA and the elevated group were 76% and 64% respectively (P=0.00019). CONCLUSION: Serum CEA seemed to be closely correlated with survival and to be an useful tool to detect recurrence after curative resection for colorectal cancer. The appropriate measurement of serum CEA might be suggested in stage II and III postoperatively: every three month for two years, every 6 month for succeeding 2 years, and annually thereafter. Monitoring of serum CEA in stage I could be individualized by preoperative serum CEA and clinical course.

PURPOSE: To determine the relation between characteristic findings of hepatic arteriography and nontumorous perfusion defects which on CT arterioportography (CTAP) had been inadequately described. MATERIALS AND METHODS: To identify pseudolesions, the CTAP results of 46 patients with perfusion defects which were not recognized on conventional CT or ultrasonography were reviewed and compared with MRI, iodized-oil CT, surgical findings, and histopathologic reports. Typical and atypical pseudolesions were divided according to location, shape and cause, as revealed in previous reports. The number, shape and the location of pseudolesion seen on CTAP were determined and hepatic arteriography correlatively reviewed to determine vascular change in the corresponding area. RESULTS: Seventy-two additional lesions of 46 patients were detected. Among these, 12 cases were true lesions. Sixty pseudolesions were divided into typical (n = 18) and atypical (n = 42) ; the typical pseudolesions were found in familiar locations adjacent to the porta hepatis, falciform ligament or gall bladder and except for increased vascular staining around the gall bladder in two lesions, specific vascular changes were not seen. The shapes of the atypical pseudolesion were wedged (n = 22), nodular (n = 15) and flat (n = 5). They were located subcapsularly (n= 30) or nonspecifically within liver parenchyma (n = 12). The early appearance of a small portal vein branch with subsequent focal hepatic parenchymal staining, which suggests a small AP shunt, was identified on the hepatic arteriography, and on CTAP matched the areas of 96% atypical pseudolesions (26/34) which were more than 1cm in size. CONCLUSION: A small AP shunt should be regarded as a cause of nontumorous, nonsegmental perfusion defectson CTAP.

We experienced a case of primary hepatic actinomycosis which was initially diagnosed by means of fine needle aspiration. The patient was a 31-year-old emaciated man with a 2-month history of 10 kg weight loss, right upper quadrant pain and flank pain. The liver was palpable and tender on physical examination. Computerized tomography scan of the liver showed two ill-defined hypodense masses in gallbladder fossa and inferior pole of right lobe. Hepatocellular carcinoma was clinically suspected. A CT-guided fine needle aspiration was performed. Microscopically, smears showed numerous radiating clusters of filamentous bacteria with many neutrophils and monocytes in necrotic background. The symptoms were improved by incision and drainage and massive administration of penicillin.
