PURPOSE: The purpose of this study was to analyze the clinical features and to assess the risk factors in the treatment of small-bowel obstructions. METHODS: This retrospective clinical report was based on the medical records of 67 patients who were treated between Jan. 1992 and Dec. 1999 and who had had a history of abdominal surgery due to cancer. RESULTS: The distribution of primary cancer was as follows: stomach cancer 36 (53.7%), colorectal cancer 25 (37.3%), uterine and ovarian cancer 4 (6.0%), and other cancers 2 (3.0%). The mean interval from the primary operation to the development of a small- bowel obstruction was 27 months. Conservative treatment produced a successful outcome in 36 patients (59.0%), but recurrences of obstruction were noted in 18 of those patients. There were 34 operations in 30 patients. The initial success rate of operative treatment was 80% (24/30), obstructions recurred in 6 patients. The causes of obstructions in the surgically treated patients were adhesion (53.3%) and recurrence of cancer (46.7%). The postoperative complication rate was 44.1%, and the mortality rate was 20.0%. The mean survival time of the patients with benign causes of obstruction was significantly longer than that of the patients with malignant causes of obstruction (46 months vs 11 months). CONCLUSION: In the treatment of such patients, conservative treatment should be considered first. However if conservative treatment fails, surgery should be done without hesitation, especially in patients with no definite evidence of recurrence.

Castleman's disease(Giant lymph node hyperplasia) is a pathologic entity of unknown etilogy, as attested to bythe number of names it has received, lymphoid hamartoma, angiomatous hamartoma, and giant lymph node, etc.Although the mediastinum is its most common location, it also occures in other areas of the body, usually wherelymph nodes are normally found. Authors have been experienced 2 cases of histologically porven Castleman's diseaseduring recent 3 years in Kyung Hee University Hospital, and present its radiological and pathological findings asmediastinal mass.

The incidence of transient bacteremia following esophageal variceal sclerotherapy (EVS) was evaluated in 29 patients. These 29 patients underwent a total of 83 sclerotherapy sessions.Prior to EVS, all instruments were sterilized. Blood cultures were drawn pre-EVS and post-EVS.All pre-EVS and post-EVS blood cultures were negative. In conclusion, it was found bacteremia following sclerotherapy is not easily developed, if a vigorous approach of using well cleaned equipment is used. Unless there is a cardiac prothesis or valvular heart disease, antibiotic prophylaxis is not warranted.

PURPOSE: Coronary artery spasm (CAS) and diabetes mellitus (DM) are implicated in endothelial dysfunction, and insulin resistance (IR) is a major etiological cause of type 2 DM. However, the association between CAS and IR in non-diabetic individuals has not been elucidated. The aim of the present study was to evaluate the impact of IR on CAS in patients without DM. MATERIALS AND METHODS: A total of 330 eligible patients without DM and coronary artery disease who underwent acetylcholine (Ach) provocation test were enrolled in this study. Inclusion criteria included both hemoglobin A1c < 6.0% and fasting glucose level < 110 mg/dL without type 2 DM. Patients were divided into quartile groups according the level of homeostasis model assessment of insulin resistance (HOMA-IR): 1Q (n=82; HOMA-IR < 1.35), 2Q (n=82; 1.35≤HOMA-IR < 1.93), 3Q (n=83; 1.93≤HOMA-IR < 2.73), and 4Q (n=83; HOMA-IR≥2.73). RESULTS: In the present study, the higher HOMA-IR group (3Q and 4Q) was older and had higher body mass index, fasting blood glucose, serum insulin, hemoglobin A1c, total cholesterol, and triglyceride levels than the lower HOMA-IR group (1Q). Also, poor IR (3Q and 4Q) was considerably associated with frequent CAS. Compared with Q1, the hazard ratios for Q3 and Q4 were 3.55 (95% CI: 1.79–7.03, p < 0.001) and 2.12 (95% CI: 1.07–4.21, p=0.031), respectively, after adjustment of baseline risk confounders. Also, diffuse spasm and accompanying chest pain during Ach test were more strongly associated with IR patients with CAS. CONCLUSION: HOMA-IR was significantly negatively correlated with reference diameter measured after nitroglycerin and significantly positively correlated with diffuse spasm and chest pain.

Even the antituberculous drugs could cure the disease itself, it might not prevent progressive kyphosis and its sequelae. Therefore, radical curettage and anterior arthrodesis with autogenous strut bone graft has been used to prevent this deformity. From May 1982 to May 1989, twenty four cases of spinal tuberculosis treated with anterior arthrodesis were analysed about the progression of postoperative kyphosis. These cases were followed up for more than 1 year at least, and the following results were obtained; 1. Lumbar spine was most commonly involved. There was involvement of one disc space in 12 cases, only narrowing of disc space in 7 cases, and two disc spaces in 5 cases. 2. The degree of vertebral loss was under 1 in 15 cases, 0 (disc space narrowing only) in 7 cases, and over 1 in 2 cases. 3. Compared with immediate postoperative kyphotic angle, there was increase of kyphotic angle in 15 cases but most of them were under 10 degress. 4. Preoperative degree of vertebral loss of 15 incerased cases was 0.5 and that of 9 decreased of maintained cases was 0.2 in average. 5. Preoperative vertebral involvement of 15 increased cases was 1.3 and that of 9 decreased or maintained cases was 1.2 in average.

Background: Although an ambulatory surgical practice continues to increase, there is a few data exist about patient discharge criteria. This study was undertaken to evaluate the usefulness and safety of Aldrete PAR (postanesthetic recovery) score and modified PADSS (modified postaneathesia discharge scoring system) on ambulatory surgery patients for recovery in Korea. Methods: Demographic, anesthetic data, Aldrete PAR score and modified PADSS on 279 patients were recorded. The time to dicharge, from recovery room and postoperative complications were evaluated, also. Results: PAR score and modified PADSS are correlated to length of stay in ambulatory surgery center. 24hr after discharge, 16% patients complained postoperative complications. Pain was most frequent postoperative complication. The PAR score was correlated with the occurrence of the complication. Conclusion: PAR score and modified PADSS are useful scoring systems to evaluate patients and make a decision to discharge the patients from ambulatory surgery center in safe.

To evaluate the isolation rate of acid-fast bacilli on Ziehl-Neelsen stain from biopsy specimens of extrapulmonary tuberculosis proven by chronic granulomatous inflammation, 286 cases of extrapulmonary tuberculosis were reviewed and the results are as follows : 1) Mean age was 27.3 years old and lymphatic tuberculosis was more prevalent in the female but others were more common in the male. 2) The most common site of extrapulmonary tuberculosis was pleura (103 cases ; 36%) followed by lymph nodes (87 cases ; 30.4%), gastrointestinal tract (27 cases ; 9.4%), skin and soft tissue (23 cases ; 8.0%), bone (19 cases ; 6.6%), urinary tract (14 cases ; 4.6%), larynx (9 cases ; 3.2%) and breast (5 cases ; 1.8%) in order of frequencies. 3) Of 286 cases, 30.4%, (87 cases) of the biopsy specimens showed acid fast bacilli on microscopy. The isolation rate according to the sites was slightly higher in breast and lymph nodes as 3 of 5 cases (60.0%) and 35 of 87 cases (40.2%) respectively, and followed by 3 of 9 cases (33.3%) in the larynx, 4 of 13 cases (30.8%) in the urinary tract, 5 of 19 cases (26.3%) in the bone, 7 of 27 cases (25.9%) in the gastrointestinal tract, 26 of 103 cases (25.2%) in the pleura, and 4 of 23 cases (17.4%) in the skin and soft tissue, in order of frequencies. 4) The prevalence of extrapulmonary tuberculosis associated with pulmonary tuberculosis on chest X-ray was 85 of 286 cases (29.7%).

Osteosarcomas are highly malignant bone tumors which commonly affect metaphyseal portions of long bones and those of the skull are distinctly rare as primary neoplasm. We report a case of recurrent osteosarcoma originated from the skull base which destructed sphenoid bone in two months. The CT and MR images of 28 years old man with headache, dizziness, and loss of touch sense in right buccal area showed 3-cm sized homogenously well-enhancing mass with internal small cystic portions. Craniotomy and mass excision was done and chemotherapy was combined for 1 month. After about 2 month, follow up MR images showed larger recurrent mass in original site and confirmed as the same osteosarcoma after 2nd operation.
