Objectives : The purpose of this study was to evaluate the clinical features of the epidermoid tumor of posterior fossa and to assess the surgical outcome. Methods : We reviewed the clinicoradiological records of 10 epidermoid tumor of posterior fossa, treated surgically at our hospital between 1991 and 1996. Results : The mean age of onset was 36 years old and mean duration of symptom was 5.2 years. Six were men and four were women. The location of tumors were cerebellopontine angle(CPA) 5 cases, cerebellum(Cbll)& 4th ventricle 3 cases, foramen magnum 1 case, and pineal region extended to Cbll and 4th ventricle 1 case. Common clinical features were trigeminal neuralgia in 3 cases, cerebellar signs 2 case, headache 2 cases, hemifacial spasm with deafness 1 case, cbll signs and multiple cranial nerve dysfunctions 1 case. One CPA epidermoid had no clinical symptom and sign associated with the tumor. The surgical approaches were suboccipital approach in 9 cases and one transcallosal approach to the tumor of pineal region. The extent of surgical removal was gross total resection in 5 cases and near total or subtotal resection in 5. Two patients with CPA tumor were complicated with facial paresis. One patient with tumor located in cerebellum extended into cisterna magna had postoperative vocal cord paresis. All complicated cases had severe adhesion of tumor capsule with brainstem or cranial nerve. The mean duration of follow up was 26 months. The overall outcome was improvement of symptoms and signs in 6 cases and stationary 4 cases. During follow up, imaging study was done in 7 patients and none of them had finding of tumor recurrence. Conclusion : We conclude that recurrence of tumor is rare in both total and subtotal resected cases, but long-term follow-up is required. Aggressive removal of tumor capsule that adhesed to brianstem or cranial nerve is avoided for preventing severe postoperative complication.

Objective : The aim of this study was to determine the efficacy of percutaneous radiofrequency neurotomy[RFN] of ramus communicans nerve in patients suffering from severe low back pain due to osteoporotic compression fracture. Methods : Twenty two patients with lumbar osteoporotic compression fracture who had intractable back pain for less than two weeks and were performed with RFN at L1-L4 from May 2004 to December 2005 were retrospectively analyzed. Clinical outcome using visual analogue scale[VAS] pain scores and modified MacNab's grade was tabulated. Complications related to the procedure were assessed. Results : Twenty-two female patients [age from 63 to 81 years old] were included in this study. The mean VAS score prior to RFN was 7.8, it improved to 2.6 within postoperative time of 48 hours, and the mean VAS score after 3 months was 2.8, which was significantly decreased. Eighteen of 22 patients were graded as excellent and good according to modified MacNab's criteria at final follow up. All patients recovered uneventfully, and the neurologic examination revealed no deficits. Two patients showing poor results worsened in symptom. Percutaneous was performed eventually resulting in symptom improvement. There were no significant complications related to the procedure such as sensory dysesthesia, numbness or permanent motor weakness. Conclusion : RFN is safe and effective in treating the painful osteoporotic compression fracture. in patients with intractable back pain due to lumbar osteoporotic compression fracture, RFN of gray ramus communicans nerve should be considered as a treatment option prior to vertebroplasty.

Objective : Pituitary apoplexy, resulting from an acute infarction or hemorrhage mainly in pituitary adenomas, is a rare yet major clinical event with neurological, ophthalmological and hormonal emergent consequences. The authors review our surgical experience with a series of 16 cases of pituitary apoplexy. Methods : The cases of pituitary apoplexy, operated via trans-sphenoidal approach in our hospital between 1998-2005, were retrospectively analyzed in terms of their clinicoradiological features, pathological findings and surgical outcomes. Results : The mean age of patients (9 male and 7 female) was 47.1 years. The average time of presentation after onset of symptom was 8.9 days. Pituitary apoplexy occurred as an initial manifestation of pituitary adenoma in all patients. Headache was the most common presenting symptom (94%). Visual disturbance was found in 56% of patients. Thirty-one percent of the patients had hypopituitarism. On magnetic resonance imaging, this entire catastrophic event accompanied with macroadenoma in a mean size of 22.5 mm. Only four patients needed postoperative hormone replacement therapy. Three of them showed preoperative hypopituitary function, and one patient in normal pituitary function. There was no specific complication in any of these patients. Conclusion : Early trans-sphenoidal decompression with high-dose corticosteroid replacement showed good outcomes of pituitary apoplexy.

Benign lung tumors compose a heterogeneous group of solid growths that present variations in clinical features, depending on whether the origin is within the bronchus on lung parenchyma or from visceral pleura. Benign tumors of the lung are relatively uncommon, and series are to be found in the literature and the classification of benign tumors of the lung continues to be controversial because of disagreement concerning the origin and prognosis of many common lesions. We adopt Liebows original classification but excluded bronchial adenoma which no longer considered as benign tumor and added pulmonary A-V fistula and congenital cystic adenomatoid malformation. We analyzed 61 cases of benign tumors which were composed of 16 original Korean cases and 45 cases which were reported on journal of Thoracic & Cardiovascular Surgery. The results were. [1] Incidence; Of 61 cases, chondromatous hamartoma was 2 cases [41 %], congenital cystic adenomatoid malformation 10 cases [16.4 %], pulmonary A-V fistula 5 cases [8.1 %], sclerosing hemangioma 4 cases [6.5 %], teratoma, plasma cell granuloma & mesothelioma were 3 cases [4.9%], Castlemans disease 2 cases [3.3%], and mucous gland adenoma, paraganglioma, and leiomyoma 1 case [1.6 %]. [2] Age & Sex distribution; Male 30 cases and female 31 cases. Mean age was 31.4 years old. [3] Main symptom; was coughing, 32.8%, and no symptom, 24.6%. [4] Sixty eight percentage of chest film showed mass density, and 4 cases showed calcification, 2 cases had lobulation. [5] Size of mass was large and multiple mass was 2 cases. Endobronchial tumors were 9 cases, 14.9 %. [6] Three cases of endobronchial tumor were preoperatively diagnosed by bronchoscopy and 2 cases of pulmonary A-V fistula were diagnosed by pulmonary arteriography. [7] Seven cases, 11.5%, had associating diseases such as bronchogenic cyst, thymic cyst, Schwannoma, situs inversus, bronchiectasis and bronchogenic carcinoma. [8] Minor resection such as excision 8i: wedge resection were 15 cases, 26.2 %, and 6 cases, 75.4 %, of lobectomy were performed including 5 cases of pneumonectomy 5 cases had. [9] Postoperative complications; One case, 1.6 %, expired due to respiratory insufficiency. Two cases had re-operation due to bleeding and hemoptysis.

Purpose: Patient quality of life (QoL) may be severely disrupted following distal gastrectomy for gastric cancer. This issue should be addressed to improve postoperative care. Materials and Methods: QoL data from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, and its gastric cancer-specific module, were administered to 202 patients preoperatively, and 5 years postoperatively. Patients were classified into subgroups based on their answers to each questionnaire item: group I (good), answering "not at all"; group II (fair), answering "a little"; group III (poor), answering "quite a bit" or "very much." Results: At 5 years post-operation, the proportion of patients in group III on the functional scales ranged from 4.3% to 5.7%. The proportions of patients in group III with fatigue, insomnia, diarrhea, and financial difficulties were 8.9%, 9.0%, 11.5%, and 9.1%, respectively. The proportions of patients in group III with anxiety, dry mouth, body image concerns, and hair loss were 12.8%, 10.5%, 9.9%, and 12.6%, respectively. These proportions were less than 5% for other QoL symptom scales/items and for the gastric cancer-specific module. Conclusions: Most patients reported good or fair QoL following surgery. However, symptom management of fatigue, insomnia, diarrhea, anxiety, dry mouth, body image, and hair loss should be specifically targeted for long-term patient care in approximately 10% of patients.

Purpose: Schwannoma, a benign peripheral nerve tumor, is slow-growing, encapsulated neoplasm that originates from the Schwann cell of the nerve sheath. Schwannoma most frequently involves the major nerve. Schwannoma occurring in the superficial radial nerve rare. This is a report of our experience with schwannoma arising from the superficial radial nerve with neurologic symptom. Methods: A 55-year-old woman presented with eight-month history of progressive numbness and paresthesia in dorsum of the thumb and index finger. Physical examination revealed a localized mass on the midforearm. Sonographic examination showed an ovoid, heterogenous, hypoechoic lesion, located eccentrically in related to the superficial radial nerve. The lesion was mobile in the transverse but not in the longitudinal axis of the nerve, which was thought to favour schwannoma rather than neurofibroma. At operation, a $20{\times}15mm$ ovoid, yellowish grey mass was seen arising from the superficial radial nerve. The tumor present as eccentric masses over which the nerve fibers are splayed. Using operating microscope, the tumor was removed, preserving the surrounding nerve. Results: Histology confirmed that the mass was a benign schwannoma. There were no postoperative complications. After two months the patient had no clinically demonstrable sensory deficit. Conclusion: An unsusual case of a schwannoma of the superficial radial nerve is presented. In case with neurologic symptom, prompt surgical decompression must be made to prevent further nerve damage and to restore nerve function early.

Objective : In the present study, we evaluate visual outcomes after surgical removal of craniopharyngiomas and analyze the factors that are considered to affect visual outcomes. Methods : This study includes 30 patients with craniopharyngioma, who underwent surgery in this clinic during the last 10 years. The changes of visual function [visual acuity and field] of the patients were assessed preoperatively and postoperatively, and paired data of this change were compared. Also, the factors that influence on this change were analysed. Results : Among the 21 patients complaining of decreased vision before the operation, 8 patients were improved [38.0%], and 7 patients were worse [33.3%]. However, Four out of 9 patients without any preoperative visual symptoms developed worse vision after the operation [44.4%]. The average duration of symptom was 17.2 months in the improved group and 23.6 months in the aggravated group. The tumors recurred in only 5 patients after the gross total resection : Four of them showed the aggravation of visual function after surgical removal and 1 had improvement. Conclusion : After removal of craniopharyngiomas, the overall rate of vision improvement, no change and aggravation are 26.6%, 36.7% and 36.7%, respectively. Aggravation of postoperative visual function is higher in males, children and patients with a longer duration of symptom and the tumor recurres more frequently in patients who complained of worsened vision after surgical removal.

Objective: Stereotactic thalamic procedure is well known to be a effective treatment for disabling upper limb tremor of essential tremor. However, the effect of this procedure for head tremor, which is midline symptom of that disease entity, has not been sufficiently established. The authors discuss the result of stereotactic thalamic operations for head tremor of their patients who suffered from essential tremor. Methods: We evaluated 4 patients of essential tremor who had head tremor combined with both upper limb tremor. One patient underwent unilateral ventralis intermedius thalamotomy, two patients had unilateral Vim deep brain stimulation(DBS) and one patient had unilateral Vim thalamotomy and contralateral DBS. Postoperative results of tremor were evaluated using our proposed scale. Results: Contralateral upper limb tremors to surgical side were markedly resolved in all patients but there was no meaningful effect for head tremor in 3 patients who underwent unilateral thalamic surgery. In a patient having simultaneously unilateral thalamotomy and contralateral DBS, remarkable improvement of head tremor was observed. Conclusion: Although it is difficult to evaluate the efficacy of thalamic surgery for axial symptom of essential tremor with a few cases, simultaneous unilateral thalamotomy and contralateral DBS would be expected to induce favorable outcomes for head tremor with significant economical advantages.

Objectives: The purpose of this study is to report the effectiveness and satisfaction of traditional Korean medicine (TKM) for enhanced recovery after surgery (ERAS) after gynecological surgery. Methods: The study is conducted by analyzing the medical records of hospitalized patients in a Korean medicine hospital. Sixty-five patients who received TKM for ERAS after gynecological surgery from May 2020 to July 2021 were included. We performed statistical analysis by using SPSS ver. 25.0. To verify the effect of TKM for ERAS, we analyzed improvement of symptoms. Also, we analyzed survey of patients' satisfaction to verify the satisfaction of TKM for ERAS. Results: Among the symptoms of pain, there was a statistically significant decrease in all types of pain on the questionnaire. Other systemic symptoms showed statistically significant improvement in all symptoms on the questionnaire. The satisfaction level questionnaires for TKM for ERAS showed a mean value of 4.37±0.63 out of 5-point scale. Especially, herbal medicine, acupuncture, and moxibustion showed high satisfaction without dissatisfaction. Conclusions: The result has shown that TKM for ERAS after gynecological surgery is effective and the satisfaction of the patients is high. Further study on TKM for ERAS for quality of life assessment is needed.
