Clonorchiasis procucts diffuse dilatation of the small and medium sized intrahepatic bile ducts and its cholangiogram shows visualization of many bile ducts, especially, tertiary, quaternary, and more peripheral tributaries up to the 6th tributaries. In an attempt to clarify this cholangiographic sign quantitively, we counted the visualized smaller bile ducts in clonorchiasis and compared the number of visualized ducts in normal cholangiogram, recurrent pyogenic chlangitis and carcinoma of the extrahepatic ducts. In clonorchiasis the number of visualized smaller bile ducts was considerably geater than in normal subjects and recurrent pyogenic cholangitis, but there was no singnificant statistical differences in the number of visualized bile duct tributaries between clonorchiasis and carcinoma of the bile ducts. Thus it is considered that too many ducts sign is not a unique cholangiographic finding of clonorchiasis, but we believe that in the presence of this sign with other we l known cholangiographic findings, diagnosis of clonorchiasis is very easy.

Pheochromocytoma stems from the chromaffin cell and mostly is located in the adrenal medulla. It is an important cause of secondary hypertension due to correction of hypertension by a resection of the tumor. Because it produces and secretes catecholamine, it bothers anesthesiologists with excessive hypertension, tachycardia and arrhythmia during the anesthetic period. Therefore, anesthetic management is directed to avoid these conditions. We report a case of bilateral pheochromocytoma successfully managed intraoperatively with an infusion of nicardipine and an intermittent esmolol injection.

Twenty-six patients with chief complaint of shoulder pain who underwent both ultrasonographic examination and arthrography of the shoulder were analyzed. Ten out of 12 cases with clinical impression of frozen shoulder, showed normal findings on the ultrasonographic examination of the shoulder. Among these ten cases, nine cases showed abhesive capsulitis and one case showed rotator cuff tear on arthrography. Among six cases with the clinical impression of rotator cuff tear, five cases showed rotator cuff tear and one case showed combined calcific tendinitis and adhesive capsulitis on ultrasonographic examination. In arthrography, four cases of rotator cuff tear, one case of calcific tendinitis and biceps tendinitis and one case of normal findings were diagnosed. For the remaining eight cases in the ultrasonographic examination, normal finding or biceps tendinitis were found and for the remaning of the cases in arthrography adhesive capsulitis were found. With the above results, we recommend that the shoulder ultrasonography as the first line diagnostic modality for a patients with chief complaint of shoulder pain.

PURPOSE: To analyze the clinical and radiological results of whole lumbosacral fusion, and to identify whether an extension of the fusion level is required. MATERIALS AND METHODS: A retrospective review was carried out on 40 patients who had undergone whole lumbosacral fusion. The adjacent segment changes were evaluated by the radiological findings including intervertebral space narrowing, traction spur, endplate sclerosis and vacuum phenomenon. The clinical results were evaluated using a visual analogue scale (VAS) and Oswestry disability index (ODI). RESULTS: The mean age was 63.8 years and the mean follow-up period was 41.7 months. At the last follow-up, adjacent segment changes were observed in 12 cases of intervertebral space narrowing, 15 cases of traction spur, 20 cases of endplate sclerosis and 8 cases of vacuum phenomenon. In the clinical results, the VAS was improved to 4.0 points from 7.6 points, and the ODI improved to 43.9% from 86.0%. There were no revision cases due to adjacent segment problems. CONCLUSION: Whole lumbosacral fusion in spinal stenosis with degenerative lumbar scoliosis was concomitant with some adjacent segment problems, but presented favorable outcomes. For the prevention of junctional problem, caution should be taken when extending the fusion level to the proximal level in whole lumbosacral fusion.

BACKGROUND: In an effort t enhance long term patency of coronary bypass grafts, utilization of arterial conduits have been on an icrease. With the same objective, we have been using the right gastroepiploic artery (RGEA) in coronary artery bypass procedures since 1998. The current paper has been undertaken with the aim of assessing the apropriateness, problems, and short term results of using the RGEA as an arterial graft conduit by studying the postoperative clinical results of 100 patients than received coronary artery bypass grafting (CARG) with this artery. MATERIAL AND METHOD: Between May of 1998 and May of 1999, an analysis of the mortality, postoperative myocardial infarction, and the need for IABP insertion as a result of low cardiac output were made between 100 consecutive patients undergoing CABG with the RGEA. There was one postoperative death due to cerebral infarction. Postoperative complications/morbidity comprised myocardial infarction in 2, cerebral infarct in 3, reoperation due to bleeding in 1, mediastinitis in 1, and low cardiac output syndrome necessitating IABP in 3 patients. Complicatons related to harvesting of the arterial grafts were not experienced in any of the patients. CONCLUSION: The results of the current data show that utilization of the RGEA in CABG is not associated with increased mortality/morbidity and demonstrates satisfactory short term results suggesting the usefulnessof this conduit as an arterial graft.

In addition to the central and the peripheral nervous system, calcitonin gene-related peptide-like immunoreactivity (CGRP-LI) has been identified throughout the enteric nervous system. Several functions of the CGRP in gastrointestinal (G-I) tract has been identified, but the effect of CGRP on G-I motility is unclear. The distribution of calcitonin gene-related peptide-like immunoreactivity (CGRP-LI) in the murine small bowel were studied by using immunohistochemistry, also analyzed functionally by using electrophysiological method. Immunohistochemical studies demonstrated that CGRP-LI is localized in both nerve fibers and myenteric ganglion cells in the whole-mount preparation of murine small intestine. Double labelling with CGRP and c-kit investigated by confocal microscope was shown that CGRP-LI enteric nerve fiber surrounded the c-kit positive interstitial cells of Cajal (ICC). Electrophysiological finding revealed that treatment of CGRP inhibited electrical activity on culture ICC. Our results suggest a CGRP innervation of murine small bowel ICC. The released CGRP from enteric nerve terminals may induce relaxation of small bowel through the inhibition of ICC.

BACKGROUND: Low flow anesthesia provides many advantages, including reduced cost, conservation of body heat and airway humidity. This study was performed to compare low flow anesthesia with high flow anesthesia and to investigate whether the advantages of low flow anesthesia during positive pressure ventilation can be combined with the laryngeal mask airway in paralyzed pediatric patients. METHODS: Thirty-one pediatric patients of ASA physical status 1 or 2 were studied and divided into two groups according to the fresh gas flow (FGF) in the breathing system; low flow group (FGF approximation 1 L/min, n = 17) or high flow group (FGF approximation 4 L/min, n = 14). Each respiratory parameter was measured when a steady state was reached at 20 min after induction. RESULTS: There were no significant differences of respiratory data between the two groups except that the inspired oxygen concentration was lower in the low flow group than in the high flow group. Hemodynamic changes with the laryngeal mask airway insertion were not statistically significant. CONCLUSIONS: A laryngeal mask airway is an effective airway device for low flow anesthesia as well as for high flow anesthesia in paralyzed pediatric patients.

PURPOSE: To improve our understanding of the pharmacokinetics of triamcinolone acetonide (TA) and TA concentration in ocular tissue, TA concentration was measured in ocular tissue after intravitreal and subtenon injection. METHODS: Fifteen rabbit eyes underwent subtenon TA injection (40 mg/1 ml), and another 15 rabbit eyes underwent intravitreal TA (4 mg/0.1 ml) injection. All eyes were enucleated at 1, 2, 4, 8, and 12 weeks after subtenon and intravitreal injection, and TA concentration in the aqueous and vitreous humor and the retina-choroid were measured by high performance liquid chromatography (HPLC). RESULTS: In cases of subtenon's TA injection, TA concentrations were 0 ng/ml, 136.7 ng/ml, 178.7 ng/ml, 0 ng/ml, and 0 ng/ml in the aqueous humor; 99.1 ng/ml, 125.7 ng/ml, 726.8 ng/ml, 0 ng/ml, and 0 ng/ml in the vitreous humor; 72.7 ng/ml, 304.6 ng/ml, 459.0 ng/ml, 0 ng/ml, and 0 ng/ml in the retina-choroid after 1, 2, 4, 8, and 12 weeks, respectively. In cases of intravitreal TA injection, the measured values were 0 ng/ml, 0 ng/ml, 0 ng/ml, 654.1 ng/ml, and 0 ng/ml in the aqueous humor; 28152.2 ng/ml, 13646.4 ng/ml, 11388.8 ng/ml, 10297.2 ng/ml, and 183.0 ng/ml in the vitreous humor; and 0 ng/ml, 27.9 ng/ml, 108.3 ng/ml, 0 ng/ml, and 0 ng/ml in the retina-choroid at each time point. CONCLUSIONS: Intravitreal TA injection may be more effective for drug delivery than subtenon TA injection, but subtenon TA injection seems to be an effective and safe technique.
