Is superselective embolization of the brain AVMs, the possibilities of adjacent normal brain tissue damage necessitates preembolic evaluation. The authors performed the Sodium Amytal test on 15 patients with brain AVMs. In the AVM patients with negative Amytal test(30 cases), all patients showed normal pattern on EEG and neurologic examinations after embolization Among the five patients with positive Amytal test, three cases showed neurologic deficit and the others two didn't. In eleven patients. Repeated embolization without the Amytal test were done. Among them, 5 cases showed neurlogic deficit and the others were quite normal. In conclusion, the Amytal test is a useful method of evaluation of the risk to damage normal brain tissue which are supplied by superselected feeding vessels. Combining the EEG with this test is a sensitive and objective method in evaluating patients following the Amytal test. And it is essential to performed the Amytal test for repeat embolization procedures.

A 45-year-old woman with recurrent disturbances of consciousness for 4 years with hypoglycemia was hospitalized with the clinical suspicion of an insulinoma. The findings of transabdominal ultrasonography, computed tomography and angiography were negative. Transhepatic venous sampling for pancreatic hormone assay showed sudden step-up of serum level of insulin in the venous blood from the tail of the pancreas. Finally, an endoscopic ultrasonographic examination established with certainty the origin of the tumor from the tail of the pancreas, which was subsequently confirmed at operation. In conclusion, endoscopic ultrasonography is a useful and valuable procedure for the localization of insulinoma especially in patient with insulinoma of the pancreas that cannot be localized by conventional methods.

A survey of intestinal parasites infection among Korean people has been carried out during July 1969 to December 1970. A total of 2,250 stool specimens (male 1,101, female 1,146) was collected from all the provinces and Seoul city in Korea. The specimens were examined routinely by direct fecal smear, zinc sulfate flotation and formalin-ether sedimentation techniques. The results are summarized as follows: Of 2,250 specimens examined, l,803(80.l per cent) were positive for intestinal parasites. The positive rates of intestinal helminths were 1,644(73.1 per cent) among 2,250; Ascaris lumbricoides 46.0 per cent, Trichocephalus trichiurus 46.8 percent, hookworm 6.8 per cent, Trichostrongylus orientalis 7.0 percent, Clonorchis sinensis 12.1 percent, Enterobius vermicularis 1.6 per cent, Hymenolepis nana 0.7 percent, Taenia species 0.3 per cent, Metagonimus yokogawai 0.04 percent, Fasciolidae 0.04 per cent and one case of lung fluke Paragonimu westermani. The positive rstes of intestinal protozoa were 786(34.9 per cent); Entamoeba histolytica 6.4 per cent, Entamoeba coli 20.5 percent, Endolimax nana 10.0 per cent, Giardia lamblia 5.1 per cent, Trichomonas hominis 1.1 percent, Chilomastix mesnili 0.5 percent, Iodamoeba butschlii 0.6 percent, Enteromonas hominis 0.7 percent, Dientamoeba fragilis 0.1 per cent and one case of Isospora hominis. Sexual distribution of helminths and protozoan infections showed higher rate in female than that of male, except C. sinensis, H. nana, Taenia species or G. lamblia Infections of T. trichiurus, hookworm, T. orientalis, C. sinensis, Taenia species, E. histolytica, E. coli and E. nana increased with age. Conversely, H. nana and G. lamblia infections were more predominent in younger ages.

BACKGROUND/AIMS: A surgical resection has traditionally been used to treat tumors of the duodenal major papilla. However, radical surgery may cause significant morbidity and mortality. Endoscopic papillectomy has been reported in patients with benign papillary tumors. We evaluated the safety and outcomes of endoscopic papillectomy in patients with a papillary tumor. METHODS: Between January 1994 and December 2003, fifteen patients with ampullary tumors underwent an endoscopic papillectomy using a snare resection. Endoscopic papillectomy was performed in 13 patients diagnosed with an adenoma and in 2 patients diagnosed with an adenocarcinoma, who were contraindicated for surgery. RESULTS: Endoscopic papillectomy was performed in fifteen patients (11 men, 4 women: median age 61.7 years). All the tumors were removed either "en bloc" (14 tumors) or in a "piecemeal" fashion (one tumor). Ten patients were available for follow-up (median, 20.9 months: range, 1~62 months). The procedure-related complications were bleeding (n=1), pancreatitis (n=3), and a duodenal perforation (n=1). The follow-up endoscopy revealed a recurrent adenocarcinoma in 2 patients after 13 months (20%). CONCLUSIONS: Endoscopic papillectomy is a useful alternative for treating a papillary adenoma. The relatively high incidence of pancreatitis this study suggests that stenting into the pancreatic duct will be needed to prevent postprocedure pancreatitis.

Endoscopic papillary balloon dilation (EBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones, EBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones. We evaluated the efficacy and complications of EBD with large balloons (10-15 mm) after limited EST for retrieval of choledocholithiasis. From February 2005, we have performed EBD with limited EST for retrieval of common bile duct (CBD) stones. The patients who admitted with hyperamylasemia and gallstone pancreatitis were excluded. In cases without CBD dilation, EPBD with 12 mm for 40 seconds was performed. And in cases with CBD dilation, we dilated the sphincters with 15 mm sized balloon for 40 seconds. Total 22 patients (11 of male) were performed EBD with limited EST for retrieval of CBD stones. The median diameter of the stones was 10 mm (5-25 mm). Ten cases had multiple stones and 6 cases periampullary diverticuli. Successful stone removal in the initial session of ERCP with EBD was accomplished in 16 patients (72.7%). And complete retrieval of bile duct stones was achieved in all patients with repeated ERCP. In the aspect of complications, any episodes of perforation, bleeding was not developed. Only one case of mild grade of post-procedural pancreatitis was noted. However, post-procedural hyperamylasemia was developed in 16 cases (68.2%). EBD with larger balloon seems to be a feasible and safe alternative technique for conventional EST in CBD stone extraction.

A consensus meeting on autoimmune pancreatitis (AIP) was held in Seoul on August 31, 2007. Many Korean and Japanese gastroenterologist interested in AIP participated in the joint symposium, and issues related to histology, radiology, clinical manifestation, serology, and diagnostic criteria were discussed. This joint meeting indicated the need for unified diagnostic criterion for AIP in Korea and Japan. Here, we provide a summary of the symposium presentations and discussions.

Agenesis of dorsal pancreas is a very rare congenital anomaly which comes from the failure of development of the body and tail of pancreas in embryogenesis. Castleman's disease is a rare lymphoid tumor which usually occurred in the mediastinum, but it is very uncommon in the retroperitoneal pancreatic tail area. We report a case of partial agenesis of dorsal pancreas with Castleman's disease in pancreatic tail area, mimicking a pancreatic tumor. A 46-year-old woman was admitted to our hospital with intermittent abdominal discomfort for 2 months. Computed tomography, magnetic resonance imaging, and endoscopic retrograde cholangiopancreatography (ERCP) revealed a tumor at distal pancreatic tail area, short pancreatic duct, and absence of pancreatic body and tail. The surgical excision of the tumor revealed hyaline-vascular type Castleman's disease.

Intramural duodenal hematoma is an uncommon condition, which usually develops after blunt abdominal trauma. It is also reported as a complication of anticoagulant therapy, blood dyscrasia, pancreatic disease, and diagnostic and therapeutic endoscopy. The typical clinical pictures of intramural duodenal hematoma consist of upper abdominal pain, vomiting, fever, and hematochezia, and it is rarely accompanied by intestinal obstruction, peritonitis, and pancreatitis as its complication. We report a case of intramural duodenal hematoma extended to peritoneal cavity, and accompanied by acute pancreatitis following therapeutic endoscopy for duodenal ulcer bleeding in a 32-year-old man who was on maintenance of anti-coagulation therapy after valvular heart surgery.
