BACKGROUND: Various surgical techniques are used for the cure of hemorrhoid according to the extent of disease and severity of symptom. Purpose : We compared the postoperative clinical course after submucosal hemorrhoidectomy and ligation and excision of hemorrhoids. MATERIAL AND METHODS: Between February 1995 and May 1997, 221 patients underwent submucosal hemorrhoidectomy and 111 patients underwent ligation and excision of hemorrhoids at the Department of Surgery, Eulji General Hospital. We compared the hospital course and postoperative complications in two group. RESULTS: For submucosal hemorrhoidectomy group, mean operation time was 38 minutes, the improvement of postoperative pain, is based on no needs of analgesics after 48 hours of postoperation, was seen in 115 patients(52.0%), wound healing took 19.5 days in average, and mean hospital stay was 6.4 days. For ligation and excision group, these findings were mean operation time 21 minutes, the improvement of postoperative pain in 47 patients(42.3%), wound healing 25.4 days, and hospital stay 7.2 days. Postoperative complications such as skin tag, edema, and were more common in submucosal hemorrhoidectomy group. But anal fissure, stenosis were more frequent in ligation and excision group, although they did not occur later. CONCLUSION: We think that submucosal hemorrhoidectomy is a better method than ligation and excision in respect of postoperative course and complications.

Mediastinum is bounded by sternum, vertebra, 1st rib, and diaphragm externally, and by pleural cavity internally and includes important structures such as great vessels, nerves, thymus and many lymph nodes. Primary and metastatic cancers, cysts and inflammatory lesions can develop in this region, and the tumor developing in the mediastinum has a tendency to developed in a specific area of mediastinum depending on the histologic type. Therefore the developing site of tumor and the clinical findings are very important in diagnosing the tumor of the mediastinum. We studied not only the characteristics of mediastinal tumor and tumorlike conditions but the histologic classification and frequency of mass to a specific area and then observed if there is any information that could help in diagnosis of the lesion of the mediastinum. Results obtained were as follows: 1) Of the 95 cases of mediastinal lesion which excludes inflammatory process, there were 70 cases (73.5%) of primary tumors, 13 cases (13.1%) of metastatic tumors and 12 cases (12.6%) of tumor-like conditions. 2) Of the 70 cases of primary tumor, 54 cases (76.8%) were benign, 13 cases (20%) were malignant and 3 cases were unclassified or unidentified tumor with the overall 3.8:1 prevalence rate of benign tumor compared to malignancy. 3) Histologic classification of the 70 cases of primary tumor showed 27 cases (28.4%) of germ cell tumor, 22 cases (23.2%) of neurogenic tumor, 7 cases (7.4%) of thymoma, 6 cases (6.3%) of lymphoma and 5 cases (5.3%) of soft tissue tumors with the highest frequency of germ cell tumor. Germ cell tumor and neurogenic tumor exceeded to 50% of total primary mediastinal tumor. 4) Male to female prevalence rate showed that benigh tumor had a high frequency in female with the the ratio of 1:1.4. But malignant tumor showed much higher frequency in male with the ratio of 4.2:1. 5) Anterior mediastinum had germ cell tumor, thymoma and lymphoma in order of frequency. Metastatic tumor was the most common in superior mediastinum. Superior mediastinum had germ cell tumor and neurogenic tumor with about the equal number, and soft tissue tumor was also developed. Middle mediastinal tumor was less common in number compared to other portions of mediastinum but the majority of tumors developed was developmental cysts and metastatic tumors. And the majority of neurogenic tumors occured at the posterior mediastinum. 6) Mass sized 5-10 cm in diameter were about 55.7% of all tumor, 2.5-5 cm and 10-15 cm were 20% respectively. But the mass sized smaller than 2.5 cm and larger than 15 cm were about 5% respectively. And the malignant tumors have more larger size than benign tumors. 7) Patient with benigh tumor had no symptoms at all or some complaints of chest tightness, dyspnea, chest pain, shoulder pain and dysphagia. In addition to above symptoms, patient with malignant tumor complained of systemic symptoms such as weight loss and fever.

The rapid frozen section method is a means of intraoperative pathological diagnosis, first introduced by Welch in 1891 and developed as a diagnostic tool by Cullen, Wilson, MacCarty et al. This method serves useful purposes, such as determining the malignancy or benignancy of a suspected lesion, determining the adequacy of a biopsy of a suspected lesion, confirming the presence or absence of metatasis, and identifying small structures. But it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations and the accuracy of the frozen section method and the materials studied was total cases of frozen section during recent 5 years. The ovarall accuracy of the frozen section diagnosis of 1,603 cases was 96.2% with 0.3% of false positive, 3.5% of false negative and 2.8% of incorrect histological diagnoses or grading errors the tissues submitted for frozen section were lymph node, breast, gastrointestinal tract and soft tissue in decreasing order of frequency. The false positive cases were four in number, while the false negative cases were 53, one third of which were the misdiagnoses of the presence of ganglion cells in Hirschsprung's disease.

BACKGROUND: Induction of anesthesia with propofol commonly associated with reduction in systemic arterial pressure, especially in elderly and high risk patients. This reduction is influenced by the dose and rate of propofol injection. The aim of this study was to examine the effect of different injection rate of propofol on vital signs, dose requirement and induction time during induction period. METHODS: Unpremedicated one hundred and twenty ASA physical status I and II patients aged 20~60 years scheduled for elective surgery were randomly allocated into one of four (150, 300, 600, 1200 ml/hr) groups according to speed of injection of propofol during induction period. Loss of verbal contact was taken as the end-point of induction. Vital signs, SpO2, dose requirement of propofol and induction time were checked. RESULTS: As the injection rate of propofol became slower, there were significant reduction in induction dose and increase in induction time (p<0.05). For example, induction dose and time were 1.82 mg/kg, 223 +/- 58 sec in 150 ml/hr group and 3.14 mg/kg, 50 +/- 11 sec in 1200 ml/hr group, respectively. Also, decrease in systolic and diastolic pressure were less marked at lower injection rates. CONCLUSIONS: Slower injection of propofol produces less vital sign changes and dose requirement for the induction of anesthesia.

BACKGROUND: Propofol is a useful induction agent, but it can cause hypotention and bradycardia. Meanwhile, ephedrine has alpha-vasoconstriction and beta-cardiac stimulant effect. The purpose of this study was to assess the hemodynamic effects of adding various doses of ephedrine to propofol to obtund adverse hemodynamic response and to determine the optimal dose. METHODS: Unpremedicated 120 ASA physical status I adult patients (20~50yrs) scheduled for elective surgery were randomly allocated into four groups according to the doses of ephedrine added to propofol (1%, 20 ml). Group 1 (control group) was given propofol alone and 10, 15 and 20 mg of ephedrine was added to propofol in Group 2, 3 and 4, respectively (n=30 for each group). Propofol was loaded at 150 ml/hr using a syringe pump and no response to verbal command was ascertained as the end-point of induction. Vital signs and SpO2 were checked every 1 min during the induction period. RESULTS: In group 1, there was a significant decrease in both systolic and diastolic pressure prior to intubation. Group 2 and 3 showed relatively stable hemodynamic changes and significant systolic or diastolic changes occured only in the pre or post 1 min periods of intubation. But, in pulse rate, group 3 showed significant change 1 and 2 min after intubation, in contrary to group 2. Group 4 showed significant changes in systolic and diastolic pressure 1 and 2 min after intubation, and in pulse rate throughout the postintubation period. CONCLUSIONS: Ephedrine 10mg may be safely employed to reduce the hemodynamic changes during induction preiod with propofol.

BACKGROUND: To estimate real time concentration of drugs during TIVA is theoretical, but it is not easy and inefficient. To maintain designed target concentration with continuous infusion using methods that account for the multicompartmental pharmacokinetic profile of fentanyl, isoconcentration nomogram is one of the methods. We evaluated the clinical usefulness of the isoconcentration nomogram using two different expected concentration of fentanyl. METHODS: Thirty ASA class I or II adult patients scheduled for spine fusion were randomly allocated into two groups according to 1.5 or 3 ng/ml of expected fentanyl concentration. Using isoconcentration nomogram, fentanyl concentration was adjusted and the propofol concentration was fixed to 3.5 g/ml according to Prys-Roberts method. Vital signs were titrated using variable flow rate of propofol. Fentanyl and propofol were discontinued 15 min before the end of operation. And, IV-PCA using fentanyl were applicated for postoperative pain control. The dosage of propofol and fentanyl, recovery time of consciousness and orientation were checked. Also, first buttoning time and 24hr fentanyl dosage in IV-PCA were checked. RESULTS: Average flow rate of propofol used were 7.5 1.2 mg/kg/hr in group 1, 5.7 1.1 mg/kg/hr in group 2 which was significantly lower than group 1 (p<0.05). Spontaneous eye opening and recovery of orientation was delayed 1.8 times in group 2. First buttoning time and 24hr fentanyl requirement for postoperative pain control using IV-PCA was delayed by 2 and decreased 60% in group 2, respectively. CONCLUSIONS: Isoconcentration nomogram was useful tool to control the expected concentration of fentanyl during TIVA and postoperative pain control using fentanyl IV-PCA.

BACKGROUND: Because of wide individual variations in response to sedative and the level of sedation desired by different patients, inadequate sedation is frequent during surgery. Patient-controlled sedation is a logical extension of patient-controlled analgesia to find and maintain their own steady-state of sedation by self-administration of sedatives during surgery. The purpose of this study was to evaluate the feasibility of patient-controlled sedation compared with anesthesiologist-controlled sedation during surgical spinal anesthesia. METHODS: Unpremedicated forty adult patients who received spinal anesthesia for lower extremity surgery were randomly allocated into two groups (n=20 for each group). After selection of target state of sedation according to sedation scale, patient-controlled sedation (PCS) group self-administered 0.5 mg (1 ml) intravenous midazolam in increments using a Walkmed PCA infusor and anesthesiologist- controlled sedation (ACS) group administered by the anesthesiologist as the same manner to achieve previously selected sedation state. Sedation score, vital signs, SpO2 were checked 5, 10, 20, 30, 40min after start of drug injection. RESULTS: The sedation scores patient desired were 4.4 +/- 0.8 in PCS group and 4.3 +/- 0.7 in ACS group. These scores were achieved 20min after start of injection in PCS group and 40 min in ACS grou p (p<0.05). Degree of satisfaction was higher in PCS group compared with ACS group (1.5 +/- 0.6 vs 2.1 +/- 0.8, p<0.05). No complications were detected in two groups. CONCLUSIONS: PCS using midazolam was better than ACS in terms of early achievement of sedation state patient desired and degree of satisfaction.

Sjogren-Larsson Syndrome is a rare disorder chracterized by congenital icthyosis, spastic diplegia or tetraplegia and mental retardation. The inheritance is autosomal recessive, due to deficiency of alcohol dehydrogenase activity of fatty acid matabolism. We have experienced a case of Sjogren-Larsson Syndrome in a 16 month-old male children who have dried thick skin, developmental delay, and spastic diplegia. He also has glistening spot on macula area with irregular high voltage slow wave (2-3Hz) on electroencephalography. From Biopsy finding, Lamella ictyosis with acanthosis and hyperkeratosis in epithelium is shown. He was much improved clinically for skin lesion and developmental status with etretinate supplement. We report the case with brief review of related literatures.
