위에서 살펴본 바와 같이 준임상적 정계정맥류이 존재가 불임 환자에서 가지는 중요성에 관하여는 아직 논란이 많다. 하지만 실제적인 정계정맥류의 크기와 신체검사에서 촉진되는 정계정맥류의 크기가 항상 일치하지는 않는다는 사실과 준임상적인 정계정맥류라 할지라도 고환에 악영향을 끼칠 수 있는 잠재력이 있음을 고려할 때, 준임상적 정계정맥류의 임상적 중요성을 결코 간과해서는 안 될 것이다. 비록 현재는 불임의 치료로서 준임상적 정계정맥류의 제거술의 잇점이 뚜렷이 규명되지는 않았지만, 불임을 주소로 내원한 환자에 있어 준임상적 정계정맥류의 존재는 항상 염두에 두어야 할 사항이라 생각된다. 또한 앞으로도 준임상적 정계정맥류의 치료 효과 및 필요성에 관하여는 잘 계획된 많은 연구들이 필요할 것으로 사료된다.

This patient was an 53-year-old man who had undergone Sengstaken-Blackmore tube insertion for esophageal varix bleeding. Two days after Sengstaken-Blackmore tube insertion, he developed severe left hemothorax and was transferred to our hospital. The esophagoscopic findings revealed a large perforation lengthening 8-cm in the intrathoracic esophagus. A left thoracotomy was performed 33 days after the injury due to repeated varix bleedings and poor conditions. An 8-cm longitudinal perforation of the intrathoracic esophagus with gross suppurative empyema was found. Primary repair and esophageal exclusion was performed 2cm proximal and distal to the perforation, using rows of nonabsorbable staplers(TA stapler 60 $\times$ 4.8) and large bore thoracostomy tubes were placed for local drainage. Six days after intrathoracic esophageal exclusion, an esophagogram revealed a leakage at just above the proximal stapling site. A cervical esophageal exclusion was performed using the same method. One hundred thirty seven days after exclusion operation for the intra-thoracic esophageal perforation, the patient was able to eat per orally without any secondary esophageal reconstructive surgery.

Brachiocephalic venous aneurysm (BVA) development is an extremely rare, particularly as a primary vascular disorder. BVAs may be misinterpreted as lymphadenopathies owing to the variable degrees of enhancement seen in imaging studies, especially among patients with underlying malignancy. We report a BVA that mimicked lymph node metastasis on CT in a 60-year-old female who had undergone subtotal gastrectomy for stomach cancer. After follow-up chest CT with different bolus times and Doppler ultrasonography, a venous aneurysm originating from the brachiocephalic vein was diagnosed. We emphasize that, to make an accurate diagnosis, physicians should be aware of the potential diagnostic pitfalls and have a high index of suspicion for BVA when encountering certain lesions in the cervical area.

A 64-year-old man was admitted for gross hematuria. Preoperative study revealed right renal cell carcinoma with inferior vena cava(IVC) tumor thrombus. Right radical nephrectomy was performed, and deep hypothermic circulatory arrest(DHCA) with retrograde cerebral perfusion(RCP) was used for extraction of tumor thrombus in the IVC. The thrombus originated from the right kidney, which extended the orifice of the gonadal vein in the left renal vein laterally, the hepatic vein superiorly, and 3cm below the right renal vein inferiorly. The thrombus was removed completely without caval wall injury under DHCA with RCP, and the postoperative course was uneventful. He received immunotherapy with interferon, and followed up without any surgical problem.

Purpose: This study was performed to review the recent experiences of pediatric gastrointestinal (GI) endoscopy done in one university hospital. Methods: A retrospective review of medical records was conducted of 1,040 pediatric cases who underwent GI endoscopy at the Pusan National University Hospital between January 2001 to June 2005. Results: A total of 1,040 endoscopies (upper 840 and lower 200) were performed. The male/female ratio was 1.25:1. Neonates and infants accounted for 6.0% and 16.5% respectively. Half of the children were below 5 years (mean age $8.5{\pm}2.1$ years). Upper and lower GI diagnostic endoscopies were performed in 634 and 163 children respectively. Abdominal pain (38.8%), vomiting (19.4%), foreign body (17.7%), and hematemesis (10.3%) were the main reasons for esophagogastroduodenoscopy. Hematochezia (56.0%), abdominal pain (27.5%) and diarrhea (3.0%) were the main reasons for colonoscopy. Upper GI therapeutic procedures included retrieval of foreign bodies, balloon dilatations of esophageal stricture, PEG, and variceal ligation in 148, 27, 15, and 3 children, respectively. Therapeutic lower GI endoscopies were performed in 37 children (polypectomy in 92%, argon lazer cauterization for angiodysplasia in 4%). Conclusion: GI endoscopy played an important role in the diagnosis and treatment of GI diseases in children. Procedures in younger aged children, cases evaluated by colonoscopy and therapeutic endoscopies are increasing in pediatric practice.

This experiment was performed to evaluate the morphological responses of the gastric epithelial cells of the mouse, inoculated with Ehrlich carcinoma cells in the inguinal area, following administration of BCG. Healthy adult ICR mice weighing 25 gm each were divided into normal and experimental groups (tumor control group and BCG-treated group). In the experimental groups, each mouse was inoculated with $1{\times}10^7$ Ehrlich carcinoma cells subcutaneously in the inguinal area. From next day after inoculations, 0.2 mL of saline or BCG (0.5 mL/25 g B.W.: $0.03{\times}10^8{\sim}0.32{\times}10^8$ CFU) were injected subcutaneously to the animals every other day, respectively. The day following the 7th injection of saline or BCG, each mouse was injected with a single dose of 0.7 ${\mu}Ci/g$ of methyl-$^3H$-thymidine (25 Ci/mmol, Amersham Lab., England) through tail vein. Seventy minutes after the thymidine injection, animals were sacrificed, and gastric tissues were taken and fixed in 10% neutral formalin. Deparaffinized sections were coated with autoradiographic emulsion EM-1 (Amersham Lab., England) in a dark room. The number of labeled epithelial cells in the gastric mucosae (mean number of labeled epithelial cells per 3.5 mm length of mucosa) were observed and calculated. And for electron microscopic observation, gastric tissues were prefixed with 2.5% glutaraldehyde-1.5% paraformaldehyde solution, followed by post-fixation with 1% osmium tetroxide solution. On the light microscopic study, gastric mucosae had no morphological changes following the injection of BCG. On the electron microscopic study, in the BCG-treated mice, myelin figures and multivesicular bodies within the gastric epithelial cells were observed more frequently than in those of the normal control ones. On the autoradiographic study, number of the labeled cells of normal control, tumor control and BCG-treated mice were 380.2 (${\pm}31.35$), 426.1 (${\pm}28.43$) and 301.8 (${\pm}34.63$), respectively. In the BCG-treated mice, poorly-labeled cells containing only a few silver grains of 3H-thymidine were observed more frequently as compared in those of the normal control and tumor control ones. From the above results, BCG may suppress the DNA synthesis of the gastric epithelial cells, but does not results severe fine structural defect on the gastric epithelial cells. These results suggest that BCG is expected as one of the effective supplemental anticancer drugs.

Between 1987 and 1994, 21 patients were treated surgically for aortic aneurysm involving the thoracoabdominal aorta. There were 11 males and 10 females, and their age ranged from 20 to 67 years old and mean age was 41.5 years. Many complained of back pain, chest pain or discomfort, and flank pain, but three patients were asymptomatic. 15 patients had chronic dissection (71.4%) and 6 had nondissecting fusiform or saccular aneurysm(28.5%), and of those 15 patients with chronic dissection, 6(28.5%) had atherosclerosis assniated with hypertension, 5 (23.8%) were Martian syndrome, and 2 (9.5%) were associated with pregnancy. The diameter of an aneurysm ranged from 6cm to 12cm, and their extent was classified as type I in 7(33.3%), type II in 8(38.1%), type III in 3(14.3%), and type IV in 3(14.3%) patients based on Crawford classification for TAA . Diseased aorta was replaced with artificial vascular graft in all but one patient. In whom the aortic tear site due to pseudoaneurysm was closed by primary suture. For the spinal cord protection during the operation, we used partial cardiopulmonary bypass (FV-FA or PA-FA bypass) in 12 patients (57.1%), Biopump (LA-FA bypass) in 4(19.0%), total circulartory arrest and CPB in 2 (9.5%), Gott's heparinized shunt in 1(4.7%), and simple aortic cross clamping in 2 (9.5%). The most common complication after the operation was hoarseness due to unilateral vocal cord palsy which onured in 5 patients (23.8%), and the next common complication was wound infection in 4 patients(19.0%), paraplegia in 2 patients (9.5%), chylothorax in 1 patient(4.7%). The hospital mortality rate was 9.5% (2deaths), and there was no late death. Our experience shows that the graft replacement of TAAA had reasonable rate of mortality, low rate of serious complication, and provided good post operative state of the pati nts, and since the thoracoabdominal aortic operation is not a high risky procedure anymore, we recommend a radical operation for the indicated patients.

To reveal the association between blood selenium level and the gastric diseases, 180 persons received the gastrofiberscopic examination at the outpatients department of the two university hospitals from July to September 1987, after the exclusion of the persons having the esophageal varix, were randomly selected. Their general characteristics such as age, sex and educational level and so on, were inverstigated. Five mi venous blood was collected from each subjects and stored at $0^{\circ}C$ in heparinized vaccum tube. The blood selenium level was measured by the flameless atomic absorption spectrophotometry. In the procedure of data analysis, five subjects having benign tumor and anomaly of the stomach, were also excluded. The mean blood selenium levels of the $155.5{\mu}g/{\ell}$ among gastritis cases, the $154.8{\mu}g/{\ell}$ gastric ulcer and the $133.0{\mu}g/{\ell}$ gastric malignancy were significantly lower(p<0.05) than that of the $173.3{\mu}g/{\ell}$ among normal controls. In men the mean blood selenium levels .among gastritis, gastric ulcer and gastric malignancy cases were significantly lower(p<0.05) than that among normal controls. In females, the mean blood selenium levels among gastritis and gastric maligancy cases were significantly lower(p<0.05) than that among normal controls($169.7{\mu}g/{\ell}$), but that among gastric ulcer cases($177.7{\mu}g/{\ell}$) was not significantly higher. In the logistic analysis, coefficient of the blood selenium level was -0.0436(p<0.05 : odds ratio 0.957) for gastritis, -0.0197(p=0.17 : 0.981) for gastric ulcer, -0.4876(p<0.05 : 0.614) for gastric malignancy and -0.0411(p<0.05 ; 0.960) for gastric diseases including the gastritis, the gastric ulcer and the gastric malignancy. These data support the hypothesis that the gastric diseases are to be associated with the low selenium level but, for the gastric ulcer, the further research is recommended.
