This is a retrospective clinical analysis of 27 cases of pancreatic pseudocysts that were treated at the Department of Surgery, Chung Goo Sung Sim Hospital, from 1988 to 1996. The results are as follows:1) The ratio of males to females was 12.5 :1, and the highest incidence was in the 4th decade. 2) Acute & Chronic Pancreatitis was most frequently associated with pancreatic pseudocysts (72.4%). 3) The most frequent symptom of patients with a pancreatic pseudocyst was abdominal pain (92.5%), and the most common site of the pancreatic pseudocyst was the tail of the pancreas (55.6%). 4) Of the 7 cases involving pseudocysts of less than 5 cm, 6 cases were managed conservatively and 1 case surgically . In the 15 cases with sizes from 5 cm to 10 cm, percutaneous catheter drainage was performed in 7 cases, with sizes larger conservative management in 5 cases and surgical management in 4 cases. In the 5 cases with sizes larger than 10 cm, percutaneous catheter drainage was performed in 3 cases and surgical management in 1 case. 5) Cases involving conservative management and percutaneous drainage (average:31 & 34 days), respectively had shorter hospital stays than surgical menagement (42 days). 6) Complications of pancreatic pseudocysts, such as intra-abdominal abscesses, cutaneous fistulas, pulmonary complications, wound infection, leakage or rupture, etc, were relatively common after surgery. In conclusion, we propose that conservative management and percutaneous catheter drainage are first-line treatment modalities for pancreatic pseudocysts if the clinical conditions of the patient can tolerate them.

In order to obsetve the effect of stroke on hypothalamic-pituitary axis, TRH stimulabon test and dexamethasone suppression test(DST) were performed in 52 patients with stroke(cerebral infarction, 16 cases; intracerebral hemorrhage, 15 cases: subarachnoid hemorrhage, 21 cases) and 15 age-sex matched patients control without intracrania disease at Keimyung University Dongsan Hospital from April 1987 to August 1988. The results summarized as follows. 1. The frequency of blunted response on TRH stimulation test is significantly higher in total stroke and patients with cerebral infarction than in control(P<0.06, P<0.05). 2. The frequency of DST non-suppression in patients with cerebral infarction is significantly higher than in control, patients with cerebral hemorrhage and patients with subarachnoid hemorrhage(P<0.001, P<0.01, P<0.01). 3. Patients with left hemispheric stroke tend to show more frequent abnormal neuroendocrine test results than patient with right hemispheric stroke. 4. There are no correlation between abnormal neuroendocrine test results and age, sex, size of stroke and Barthel ADL scale. These results suggest stroke can influence on hypothalamic-pituitary axis, more marked in cerebral infarction and left hemispheric lesion.

The authors analysed the CT findings in 75 cases diagnosed as gastric carcinoma by U.G. I.S. or endoscopy in a 3)1, year period. The comparative analysis betw~en CT findings and surgical pathologic findings was done in 55 cases who underwent surgery. 20 cases could not be operated upon because of distant metastasis. The gastric carcinoma was devided into 4′ stages according to the staging system of the American joint Committee on Cancer. The CT findings were then compared and the following results noted : 1. The relationship with gastric wall thickening and penetratioil degree of tumori no thickening (Iesser than 1.0 cm) of 3 cases showed all of T1, 11 of localized thickening (1. 0.1 .5cm) showed 7 of T2, 38 of localized thickening (more than 1.5 cm) showed 37 of T3 and 3 of diffuse thickening showed all of T4a. 2. The accuracy of Iymph node detection by CT scan, 1) Regionaf tymph node showed 86% in operative f in ding and 73% in pathologic. 2) Extragastric Iymph node showed 87% in operative finding and 89% in pathologic. 3) Retro-peritoneallymph node showed 96% in operative finding and 95% in pathologic. ic. 3. In operated cases, there was one case of false positive distant metastasis and three false negative cases. 20 cases of non-operated cases showed distant metastasis such as liver, lung or kidney. 4. 55 cases were classified as stage 1 in 4 cases, 11 in 18, 111 in 23 and IV in 10 by pathologic findings, and 1 in 3, 11 in 24, 111 in 19 and IV in 9 by CT. The overall accuracy by CT stagi ng is 75%. 5. Among a total of 75 cases, there were 46 operable cases by CT finding an d 43 operabl e cases by pathologic staging. There we re 29 inoperable cases by CT finding and 27 cases by pathologic staging. Therefore, there was a 93% overall accuracy by CT stagi ng in terms of determination of operability. 6. The accuracy of adhesion into adjacent structure by CT finding was 69%. compared with operable finding.

Gastric cancer occurs with high frequency and is a significant cause of cancer motality in Korea. The most common metastatic sites of gastric cancer are liver, lung, bone and adrenal gland. Intramuscular metastasis from gastric cancer is an rare case. Skeletal muscle is one of the most unusual sites of metastasis from any malignancy. We report an elderly patient with gastric cancer developing multiple metastasis in skeletal musle.

Angioedema is a well-demarcated localized edema involving the deeper layers of the skin, including the subcutaneous tissue. Angioedema occurs with Cl esterase inhibitor (Cl INH) deficiency that may be inborn as an autosomal dominant characteristic or may be acquired. Acquired angioedema (AAE) is a rare disorder characterized by adult onset and lack of evidence of inheritance of the disease. Two types of AAE are known today: type I in which there are lowering of functional Cl INH, an underlying disease such as a B-cell disease, and no detectable autoantibodies to Cl INH, type II with anti Cl INH autoantibodies in the circulation without detectable underlying disease and with depressed functional Cl INH levels. We experienced a case of angioedema in a 29-year old man. He had no family history of angioedema and laboratory data showed depressed Cl-INH levels. We diagnosed the case as acquired type of angioedema. Even though we could not measure anti-Cl INH auto-antibodies, we identified the case as type II because there was no evidence of underlying disease.

OBJECTIVE: To review recurrence and prognosis of microivasive squamous cell carcinoma of the cervix that are associated with depth of invasion, pathologic finding and management(conservative or radical treatment) STUDY DESIGN: We conducted retrospective study in order to evaluate the results of therapeutic approaches in 46 patients with microinvasive cervical cancer from Jan 1987 to Oct 1996. RESULT: The mean age of patients was 44.6+ 8.86 years. Only one woman was nullipara, and the mean parity was 2.8, Overall diagnostic accuracy of pap smear and punch biopsy were 54.3% and 79.4%. As the depth of invasion was deeper, the diagnostic accuracy of punch biopsy increased(p<0.05), The confluence pattern and lymphovascular space involvement were observed in 39.1% and 4.9%. The confluence pattern was observed with statistical significant in advanced depth of stromal invasion. In the surgical management, vaginal hysterectomy was done in 28 patients, conization(l patient), total abdominal hysterectomy(8 patients) and radical hysterectomy with pelvic lymph node dissection(9 patients) was done, no positive node was in 104 pelvic lymph node dissected. Though all cone margin was free and all endocervical curettage was negative, residual lesion(2 patients) was present in the hysterectomy after conization, The median follow-up period was 64 months. There was no recurrence in all cases and 5 years survival rate was 100% CONCLUSION: We suggest that microinvasive carcinoma of the cervix may be the disease of good prognosis and no recurrence, and less radical therapy for the patients with microinvasive carcinoma may be sufficient.

OBJECTIVE: This study was done to propose a new method of determining the cutoff frequency against measurement noise in fetal heart rate signal and to analyze the discriminating value for normal fetus (pH>7.15) and abnormal fetus (pH< or =7.15) by nonlinear method. METHODS: The patients were classified by umbilical artery pH (7.15) or base excess (-10 mEq/L). After removing the high frequency noise components at the cutoff frequency determined in this study, we calculated correlation dimension as a discriminating value for the normal and abnormal fetuses. RESULTS: After low pass filtering of fetal heart rate signal at the cutoff frequency, the numerical result of embedding dimension was 5.47+/-0.67 (normal), 4.43+/-0.60 (abnormal) (p<0.001), and correlation dimension was 2.51+/-0.43 (normal), 1.79+/-0.15 (abnormal). CONCLUSION: We could determine the cutoff frequency from the different fluctuation level between high frequency noise and principal signal according the cutoff frequency function. The detection of fetal distress was done objectively by this method. We could discriminate between normal fetus and abnormal fetus by correlation dimension as indicator for the nonlinear complexity.

OBJECTIVES: For estimating the antenatal fetal wellbeing to develop new analysis method of fetal heart rate(FHR) with electronic Fetal Heart Rate Monitoring(eFHRM) and computer. METHODS: Heart rate signal is received from distressed fetus using eFHRM. It is necessary to carry out low pass filtering as a preprocess for the nonlinear method. Nonlinear parameters are calculated and classified to investigate the relations between these parameters and values of umbilical cord blood gas. RESULTS: By dividing values of the umbilical cord blood gas into 5 fetuses of acidemic group and 17 fetuses of non-acidemic group after 22 neonates who presented fetal distress were born, the following results as compared with nonlinear chaotic analysis result were obtained. 1. Delay time through AMI for acidemic group was 16.80+/-3.11, and was higher than 15.41+/-2.27 for non-acidemic group, and is not significant in statistics. 2. Embedding Dimension calculated with FNN method was 5.60+/-2.07 for acidemic group, and 4.71+/-1.26 for non-acidemic group, and it was not significant statistically. 3. Correlation dimension for acidemic group was 1.41+/-0.20, and was higher than 1.10+/-0.38 for non-acidemic group, and is not significant in statistics. 4. Mean crossing value by isoangular return map was 28.80+/-11.34 for acidemic group, and 16.65+/-7.00 for non-acidemic group, and it was significant statistically(P=0.008). 5. In comparison of information entropy in 1-D ED, acidemic group was 6.32+/-0.38 and non-acidemic group was 6.20+/-0.28 and it was not significant statistically. Also, in comparison of value in 2-D ED, acidemic group was 10.20+/-0.34. It was higher than non-acidemic group of 9.51+/-0.43 significantly in statistics(P=0.004). But, in comparison of value in 2-D EP, acidemic group was 8.78+/-0.86 and non-acidemic group is of 9.22+/-0.74 and it wasn't significant statistically. And, 2-D ED(DI) value was 10.64+/-0.14 for acidemic group and 10.51+/-0.18 for non-acidemic group, and it wasn't significant statistically. CONCLUSIONS: By the above result, nonliner dynamics and chaotic analysis of heart rate data with computer can serve as a new diagnosis method which may estimate the fetal wellbeing with real time. Through further studies for establishment of diagnosis standard and computer programming, real time diagnosis method shall be applied to clinical practice.

Intrasellar or pituitary abscess was first reported about a century ago, after then once relatively common but now is rare. Since 1925, about 50 cases have been reported in the literatures, of which characters were variable, but clinical very similar to one of pituitary tumor. So they were often diagnosed preoperatively as pituitary tumor. Several pathogenic factors were postulated in relation to clinical aspects. We had recently experienced a case of pituitary abscess combined with chromophobe adenoma. A 28 years old clerkman was admitted to our hospital with complaints of impared ejaculation and visual disturbance. Clinical aspects and diagnostic studies gave us a strong impression of pituitary tumor. Upon surgery we found a cystic mass in pituitary region, of which aspiration showed whitish-gray, tenacious and liquid material. Many polymorphous leukocytes were noted by direct smear, but no microorganisms were detected in culture. He had postoperatively suffered from transient polyuria and polydipsia, which soon disappeared under the medication of Esidrex. He was discharged from this hospital with recommendation of radiation therapy. Clinical features and treatment were also discussed with review of ever reported cases.

A number of authors have called attention to the difficulty encountered in diagnosing tumors near the foramen magnum and have formulated symptom complexes in an effort to facilitate early recognition of these lesions. Emphasis has been placed on their bizarre symptoms and on their resemblance to the clinical picture associated with some degenerative diseases of the central nervous system, ruptured cervical disc and cervical spondylosis. Fortunately, it has been known that most of tumors around the foramen magnum are benign, extramedullary and amenable to cure by surgical excision and with minimal morbidity and mortality, provided they are diagnosed early. Recently we experienced a rare case of glioblastoma multiforme at the cervico-medullary junction. A 28-year-old Korean man was admitted to the Dept. of Neurosurgery on May 27, 1974, with 5 months history of cervical and suboccipital pain, and progressive visual disturbance. He had sustained hyperextension injury to his neck 8 months ago, and subsequently developed mild suboccipital and cervical pain which subsided easily with some analgesice. Three months later, he noticed paresthesia and tingling sensation in his upper limbs and anterior chest, especially when he turned his neck to either side. He also had pain in suboccipital region radiating to his both shoulders. Seven months later, he developed sudden paraperesis, poor vision and incoordination with severe suboccipital headache and vomiting. On admission, neurological examination disclosed clear consciousness, bilateral papilledema and abducens nerve palsy and markedly decreased vision. There were clumsiness of movement of both legs, hypesthesia in the face, decreased perception of vibration and position sense below the neck and increased deep tendon reflexes. Fine coordination movements in the upper limbs were disturbed and horizontal hystagmus was also present. Simple skull films showed destruction of the dorsum sellae and the posterior clinoid process, suggesting increased intracranial pressure. Cervical spine films were interpreted as normal. Right carotid angiograms demonstrated marked hydrocephalic patterns, and right vertebral angiograms demonstrated posterior displacement of the tip of the basilar artery and of the choroidal point. Conray ventriculogram showed a sharp filling defect at the level of lateral recess of the fourth ventricle. Suboccipital craniectomy and bilateral laminectomy of the first two cervical vertebrae were performed, disclosing a nodular, meaty, firm mass with some necrosis. The tumor was located posterolateral to the medulla and the spinal cord from the obex to the C2, compressing them and displacing the right cerebellar tonsil upward and laterally. The tumor was removed partially and Torkildsen's shunt was performed. Post-operatively he died suddenly at the end of the second week without any remarkable improvement in symptoms and signs. Pathological report was a glioblastoma multiforme. At autopsy, the tumor was originated from the cervicomedullary junction, extending posteriorly from the obex to the C2 and anteriorly along the brain stem up to the perichiasmatic region.
