A 60-year-old woman has experienced of right upper quadrant abdominal discomfort. This partient took cholecytectomy due to gall stone 15 years ago. At that time microscopic finding the neck of gallbladder showed well differentiated papillary adenocarcinoma confined to superficial part of musele layer. 3 years before admission she took T-tube drainage due to obstructive jaundice. The microscopic finding af distal common bile duct showed well differentiated adenocarcinoma. Recently she complained of pain and discomfort on T-tube site and so we perforrned endoscopic retrograde biliary drainage after removal of T-tube. The computed tomogram showed no mass in liver or lymph node enlargement. 4 months after procedure of ERBD; we changed to the new catheter for the prevention of cloggiag of prosthesis. We report here a case of longterm survival over 15 years after the diagnosis of cancer of extrahepatic bile duct.

OBJECTIVE: This study was carried out to evaluate the effect of the isolation methods of inner cell mass from mouse blastocyst, types of feeder cells and treatment time of mitomycin C on the formation rate of ICM colony. METHODS: The inner cells were isolated by conventional immunosurgery, partial trophoblast dissection with syringe needles and whole blastocyst co-culture method. Commercially available STO and primary cultured mouse embryonic fibroblast (pMEF) feeder cells were used, and mitomycin C was treated for 1, 2 or 3 hours, respectively. The formation rate of ICM colony was observed after isolation of ICM and culture of ICM on the feeder cells for 7 days. RESULT: The ICM colony formation rate on STO were significantly higher in partial trophoblast dissection group (58%) than that in immunosurgery (12%) or whole blastocyst culture (16%) group (p<0.05). The formation rate on pMEF feeder layer was higher in partial trophoblast dissection (88%) and whole blastocyst culture (82%) group than that in immunosurgery (16%) group (p<0.05). When mitomycin C treated to pMEF for 2 hours, the formation rate of 88% was significantly higher than those of other conditions. CONCLUSIONS: Above results showed that the efficient isolation method of ICM from blastocyst was the partial trophoblast dissection and the appropriate treatment time of mitomycin C was 2 hours. However, the subculture of ICM colony and characterization of stem cells should be carried out to confirm the efficacy of the partial trophoblast dissection method.

BACKGROUND: The optimal management of malignant obstruction of the left colon and rectum is controversial. METHODS: A retrospective study was performed of 33 patients who underwent one-stage operation(n=11), staged operation(n=20), and palliative colostomy(n=2) at Kwangju Christian Hospital between January 1992 and December 1996. RESULTS: Eleven patients underwent one-stage operations(7 cases with anterior resection, 3 cases with left hemicolectomy, 1 case with Miles' operation). In this group, postoperative morbidity was 36.3% including 1 wound infection(9.0%), 1 anastomotic leakage (9.0%), 1 postoperative intestinal obstruction and 1 pulmonary complication, but there was no postoperative death. The average of hospital stay in this group was 18.1 days and the first day of normal diet was 6.0 days. Twenty patients underwent staged operations including 12 cases of Hartmann's procedure. In this group, postoperative morbidity was 35.0% including 3 wound infections(15.0%), 2 pulmonary complications(10.0%), 1 parastomal hernia and 1 fistula. There were two postoperative deaths as a result of sepsis. The average of hospital stay in this group was 34.9 days and the first day of normal diet was 6.8 days. CONCLUSION: We believe that one-stage operation was of value in management of malignant obstruction of the left colon and rectum in selected patients.

Endoscopic nasobiliary drainage(ENBD) has been developed as a safe and effective noninvasive biliary drainage method for initial decompression in the benign or malignant biliary obstruction, dissolution of biliary stones by injection of litholytic agents through the tube, and proper causative diagnosis of biliary obstruction by cytologic, bacteriologic and parasite investigation of drained bile. Generally, endoscopic sphicterotomy (EST) is performed before the insertion of an ENBD tube in order to make the procedure easy and to prevent acute pancreatitis that may develop by compression of the pancreatic orifice of the inserted tube. Nevertheless, in some cases EST is difficult to perform or should not be performed due to their coagulopathy. In such cases, ENBD without EST may be necessary. To evaluate the safety, successfullness and effectiveness of ENBD without EST, ENBD without EST using 5, 6 or 7 Fr pigtail tubes were performed in 81 cases(49 malignant, 32 benign). ENBD without EST was successfully performed in 78 out of 81 cases(96.3%). This effectiveness for decompression of bile duct, evaluated by decreasing total bilirubin values, was good in 66 out of 73 casee (90. 2%). The complications of this procedure were noted in 6 out of 78 cases(7. 7%). e. g. cholangitis in 3, migration of ENBD tube in 2, acute pancreatitis in 1 case. Particularly, regardless of our concern that ENBD without EST may develop acute pancreatitis acute panereatitis was noted in only one case. In conclusion, ENBD without EST is a safe and effective method which can be applied to the cases who have benign or malignant obstructive jaundice.
