Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most useful diagnostic tool in biliary and pancreatic disease. However, ERCP cannot be performed successfully in all patients. Cannulation failure is the most common cause of failure of ERCP. Mechanical pathologies, such as peri-Vater diverticulum, cancer of the papilla of Vater, and impacted stone were the common causes of cannulation failure. We experienced two cases of carcinoma of the papilla of Vater in whom cholangiography and insertion of the nasobiliary tube were performed througth an artificial choledoehoduodenal fistula made by a needle type diathermy knife, beacuse cannulation to the duct was failed due to the tumor.

The localizations and morphological characteristics of gonadotropes in the adenohypophy-sis of Korean native goat were investigated with double immunohistochemistry. The gonadotropes were present in the pars distalis and pars tuberalis, but not in the pars intermedta. Gonadotropes occupied about 49.0% of the cells in the pars distalis in females, and about 40.8% in males. Three types of gonadotropes ; FSH immunoreactive cells[FSH cells], LH immunoreac-tive cells[LH cells], and FSH and LH immunoreactive cells[FSH/LH cell], were identified according to their immunoreactivities for FSH and LH antisera. The possessional perce-ntages of FSH cells, LH cells and FSH/LH cells were 1.1%, 40.6%, 58.3% in females and 1.8%, 30.0%, 68.8% in males, respectively. FSH/LH cells were large and oval or round in shape. These cells were distributed throughout the pars distalis, but were more abundant on the dorsal part adjacent to the hypophyseal cavity and along the lateral and ventral peripheral regions. LH cells were smaller than other gonadotropes and were observed throughout the pars distalis, but predominant in the central region. FSH cells were large and oval in shape. These cells were intercalated between FSH/LH cells.

To evaluate the influence of intraoperative irradiation on the healing of jejunal anastomosis, an experimentalstudy was undertaken using a total of 150 rats. The bursting pressure of the normal jejunum was obtained in groupI. Group II was subjected to resection and anastomosis, and group III was irradiated on the anastomosed jejunumwith a single dose of 1,000 rads. Healing process was evaluated by measuring bursting pressure of the anastomosedjejunum on each postoperative day from 2nd to 14th, and on 21 th day. Bursting pressure was tested by inflatingthe loop of gut with water, and bursting sites were observed. The resuls obtained are summarized as follows; 1.The bursting pressure of the anastomosed jejunum retained normal strength by the 7th postoperative day in thenonirradiated group, whereas by the 11th postoperative day in the irradiated group. 2. Irradiation caused delay inthe healing of anastomosis of the jejunum until the 10th postoperative day; but after then, there was nosignificant difference in bursting pressure between both groups. 3. In the jejunal segments with normal strength,bursting occurred exclusively at the non-anastomotic site in both groups; Bursting started along the mesentericborder in the non-irradiated group, whereas rupture usually occurred on the antimesenteric border in theirradiated group. in the jejunal segments with subnormal strength, bursting usually started on the mesentericborder of the anastomotic site in both groups. The results indicate that intraoperative irradiation with a singledose of 1,000 rads causes no harmful effect on the healing of anastomosis of the jejunum in rats. Therefore, thisstudy suggests the possibility of more effective clinical application of intraoperative irradiation.

PURPOSE: This study was made to evaluate the clinical characteristics of testicular microlithiasis which shows small diffuse hyperechoic nonshadowing foci throughout both testes on sonography. MATERIALS AND METHODS: Between July 1995 and May 1997, we had seen 15 Patients with dilateral diffuse microlithiasis of the testes on the sonography. Medical records were reviewed with respect to age at presentation, associated diseases, and sonographic and pathologic characteristics. RESULTS: The age of the patients ranged from 8 to 69 years. The testicular microlithiasis was coincidental to the presence of erectile dysfunction(n=5), epididymitis(n=5), varicocele(n=4), epididymal cyst(n=2), infertility(n=1), testicular teratoma(n=1) and diabetes mellitus(n=1). There were considerable variations in the numbers of echogenic foci on each sonography that examined the entire half of the scrotum(from 15 to more than 60 foci). The histological examinations were done in two patients and sbowed the lumina of seminiferous tubules filled with concentrically lamellated calcified concretions. CONCLUSIONS: The testicular microlithiasis showed a wide range of age at presentation and associated with diabetes mellitus and a variety of urological problems including erectile dysfunction, epididymitis, varicoce18, epididymal cyst, infertility and testicular teratoma. The clinical relevance remains unclear at this time. Further additional cases as well as a long-term follow-up would be necessary to assess the association between testicular microlithiasis and these coincidental conditions.

BACKGROUND: Adult with congenital heart disease represents a new category of specialized cardiovascular interest that requires the cooperation of a number of medical and surgical disciplines, and also requires the interactions among traditional departmental jurisdiction. Uninterrupted, long-term continuity care is essential if the concerns inherent in this new and increasing patient population are to be addressed. The purpose of this study was to analyze the clinical characteristics of congenital heart disease in adolescents and adults. METHODS: Between October 1994 and July 1996, retrospective follow-up records and registry chart of 229 consecutive patients with congenital heart disease for over 16 years in GUCH (grown-up congenital heart) clinic were reviewed by a physician and a nurse specialist. RESULTS: There were 126 female and 103 male GUCH patients with the mean age of 34+/-14.6 years old. Among the 229 patients, there were 179 natural survivors, those without cardiac repair, and 50 postoperative survivors. Congenital heart defects were 167 shunt legions, 17 obstructive and valvular legions, 14 tetralogy of Fallot, 15 complex congenital heart anomalies and 16 others. Among the 179 natural survivors; 122 (68%) required heart surgery or continuous medical surveillance, and among the 50 surgically repaired survivors; 37 (74%) required reoperation for residual heart defects, constant medical treatment or consultation from other medical divisions. The reasons for the hospital vistis were:cardiac operation or cardiac diagnosis in 128 (56%) patients, symptomatic heart conditions in 43 (19%), routine heart examinations since childhood in 31 (14%) and others in 27 (11%). Also, the patient compliances were higher in the GUCH clinic than the traditional departmental jurisdiction (p<0.001). CONCLUSIONS: To achieve continuing care for the patients with congenital heart disease in adolescents and adults, it is important to develope a specialized clinic addressing the specific needs of the congenital heart disease in adolescents and adults.

PURPOSE: To prevent permanent neurologic deficit and/or spinal deformity in pyogenic spondylitis earlydiagnosis and prompt treatment are essential. The purpose of this study is to determine the MR imaging findings ofpyogenic spondylitis. MATERIALS AND METHODS: In 31 patients with pathologically or clinically proven pyogenicspondylitis, MR images(31, T1-weighted ; 30, T2-weighted ; 31, Gd-enhanced T1-weighted) were retrospectivelyanalyzed. Analysis focused on the signal intensity and enhancement pattern of involved vertebral bodies andintervertebral discs, as well as paravertebral soft tissue abnormality. RESULTS: A total of 77 vertebral bodies(mean, 2.5 per patient) were involved. Signal intensity was low in 58 of 77 T1-weighted images, high in 63 of 75T2-weighted images and in 72 of 77 contrast-enhanced T1-weighted images, enhancement was diffuse. A total of 47intervertebral discs were involved. Signal intensity was low or intermediate in all 47 T1-weighted images, andhigh or intermediate in 38/46 T2-weighted images ; in 24 of 38 contrast-enhanced T1-weighted images, signalintensity was peripheral, and in 14, enhancement was diffuse. Twenty-six patients showed diffusely enhancedparavertebral soft tissue abnormality and in 14, the largest diameter was less than 1cm. CONCLUSION: With regardto vertebral bodies, MR imaging findings of pyogenic spondylitis are low signal intensity on T1-weighted images,and high or intermediate signal intensity on T2-weighted images, together with diffuse enhancement. Forintervertebral discs, signal intensity was low on T1-weighted images, high on T2-weighted images, and peripheralor diffuse enhancement was seen. Diffusely enhanced small paravertebral soft tissue abnormality was also present.

PURPOSE: To evaluate the MR imaging findings and gadolinium enhancing patterns of Kienboeck's disease. MATERIALS AND METHODS: Thirteen patients with Kienb ck's disease were included in this study. T1 and T2 or T2*weighted images(WI) were taken in all patients and gadolinium enhancement was performed in six patients. We compared MR signal intensity of lunates with that of normal bone marrow. MR imaging findings and stages accordingto Lichtman's classification were correlateds and we evaluated the enhancing patterns of the lunates and synovia. RESULTS: Stage II was found in five patients, stage III in seven, and stage IV in one. T1WIs showed low or focaliso signal intensity in all patients. T2WI showed low signal intensity in three patients and focal iso or focal high signal intensity in ten. There were no significant correlations between the signal intensity of lunates and stages. Synovial enhancement was detected in five patients. In four, the areas of focal iso or high signal intensity on T2WI were the enhanced areas of lunates. CONCLUSION: Kienb ck's disease showed low signal intensityon T1WI in all patients and variable signal intensity on T2WI. There was no significant correlation between MRsignal intensity and Lichtman's stage. Synovia and the areas of focal iso or high signal intensity on T2WI were frequently enhanced.
