Spontaneous perforation of bile duct in adults is very rare, with less than 30 cases described in the literature to date. We repoit a case of a 65-year-old man who presented with severe colicky abdominal pain and fever, just like symptoms of peritonitis. ERCP provided a preoperative noninvasive confirmation of the diagnosis of the rupture of right intrahepatic duct. The patient was performed T-tube choledochotomy and drainage of retroperitoneal bile collection. The etiolgy, diagnosis, and treatment of spontaneous perforation of bile duct is discussed.

BACKGROUND: To find out characteristics and classification of toxic agents by clinical analysis of pediatric poisoning and to determine the clinical availability of grading by using MSPC score. METHOD: Subjects were patients under 15 years exposed to toxic agents, who visited Ajou university hospital emergency center from June, 1994 to October, 1997. The study was performed retrospectively. RESULTS: The subjects were 126 cases and male to female sex ratio was 1.2:1. Mean age was 29+/-30 months old. The most common route of exposure was ingestion, following contact, inhalation and bite. The most common reason was mistake by the patient, following mistake by caregiver, suicide attempt and accident. The MSPC score distribution of symptomatic patient was as follows; 1 point: 26 cases(63.4%), 2 point: 12 cases(29.2%), 3 point: 1 case(2.4%), 4 point: 2 cases(4.8%). The classification of exposed poison was as follows; therapeutic drugs: 29 cases(23.0%), non-therapeutic drugs: 97 cases(73.0%). The most common exposed poison was household products: 23 patients(18.3%) were admitted to hospital. CONCLUSION: There was statistically significant difference in the classification of poison, MSPC score, treatment modality at hospital, first follow up period after discharge between admitted group and non-admitted group. There was statistically significant difference in the reason of exposure, route of exposure, MSPC score, admission period according to patient's age. severity grading according to MSPC score is regarded as an available method to determine the modality of management.

Inadvertent application of ionizing radiation, a valuable tool in diagnostic radiology and radiotherapy, results in injury and death of adjacent normal cells, inducing gene mutations or even producing latent cancers. Captopril, an angiotensin I converting enzyme (ACE) inhibitor, has been reported to prevent the structural and functional changes in variable organs, such as lung and kidney, from radiation injury in different experimental animal models. An experiment was carried out to elucidate the radiation-induced histomorphologic changes of small intestine, especially jejunum, and to determine whether captopril can reduce or prevent the radiation-induced injuries in jejunum. Twenty-six healthy Sprague-Dawley rats were used. Experimental group (n=24) was divided into two large groups: the first one (n=16) was treated with two different single dose (9 Gy, 17 Gy) irradiation only and was sacrificed at 12 hours and at 8 weeks following irradiation; the second one (n=8) received captopril 500 mg/l per oral continuously after same doses of irradiation and was sacrificed at 8 weeks. The control group (n=2) was maintained on a stock diet in a same period of experimental group and sacrificed coincidentally. On light and electron microscopy, the 9 Gy and 17 Gy 12 hours groups revealed frequent apoptosis and necrosis but extremely decreased mitotic figures of the crypt cells. However, the 9 Gy and 17 Gy 8 weeks groups and the combined irradiation with captopril groups showed extremely reduced apoptosis and necrosis with increased mitotic figures. There was good correlation between experimental groups in apoptotic count and mitotic count (p<0.05). In the 9 Gy and 17 Gy 12 hours groups, the mucosal surface was focally or diffusely fragmented and the villi were slightly to moderately distorted. Collagen deposition was very mild and confined to the lower portion of the lamina propria. The 9 Gy and 17 Gy 8 weeks groups showed more severe mucosal surface fragmentation even with foci of erosion, short and distorted villi, and more intense collagen deposition. In contrast, the combined irradiation with captopril groups revealed complete regeneration of the mucosal surface epithelium and absent collagen deposition. These findings suggest that the acute radiation injuries to small intestine occur principally in the mucosal crypt cells. Captopril, the ACE inhibitor, might provide a useful intervention in the radiation injuries of intestinal mucosa.
