Background and Objectives: Neck metastasis is one of the most important prognostic factors in treating tonsillar cancer. Incidence and pattern of lymph node metastasis of tonsillar squamous cell carcinoma are the basic knowledge of treatment decision. Occult metastasis rate of tonsillar cancer and pattern of metastasis, failure pattern, survival were retrospectively analyzed. Patients and Methods: Seventy six patients who underwent surgery for tonsillar squamous cell carcinoma as an initial treatment from 1992 to 2004 were evaluated. Charts, imaging studies and pathologic reports were reviewed. Results: At the time of surgery, 78% of patients with tonsillar cancer had neck metastasis and 66% had multiple node metastasis. Occult neck metastasis was in 26%. There was high incidence of neck metastasis even in early stage of primary lesion. Conclusion: High incidence of lymph node metastasis was confirmed histopathologically in tonsillar cancer. All tonsillar cancer patients may need elective treatment of the neck. Tonsillar cancer had relatively good prognosis even though its neck metastasis rate is very high.
Background: Anticoagulant therapy can be required during pregnancy with prosthetic heart valves. Warfarin and heparin provide real protection against thromboembolic phenomena, but they also carry serious risks for the fetus and the mother. In an attempt to identify the best treatment for pregnant women with cardiac valve prostheses who are receiving anticoagulant, we studied 19 pregnancies, the warfarin was discontinued and heparin was administered every 12 hours by subcutaneous injection in doses adjusted to keep the midinterval aPTT in the therapeutic range(at least 2-2.5 control) from the conception to the 12th week of gestation and oral antiocagulant was then administered until the middle of the third trimester in the therapeutic range(at least 2 INR), and heparin therapy was restared until delivery. Also in order to avoid an anticoagulant effect during delivery, it has been our practice to instruct women to either discontinue their heparin injections with the onset of labur or to stop heparin injections 12 hours prior to the elective induction of labour. Result: The outcome of 19 pregnancies managed with above protocol was spontaneous abortion in 3 cases, voluntary termination in 2 cases, premature delivery at 35 weeks in 1 case and delivery at full-term in 14 cases. There was no maternal morbidity and moratality and fetopathy. Conclusion: We conclude that in the second and third trimester of pregnancy, warfarin provide effective protection against thromboembolism, Oral antiocagulant therapy should be avoided in 2 weeks before delivery because of the risk of serious perinatal bleeding caused by the trauma of delivery to the anticoagulated fetus. However, the substitution of heparin at first trimester and 2 weeks before delivery reduce the incidence of complications.
Purpose: A descriptive study was conducted to examine the levels of distress, state anxiety, and physiologic responses in postoperative patients under patient controlled analgesia (PCA), and to determine correlations among the variables. Method: The study sample included women who underwent an elective hysterectomy procedure or other gynecologic surgeries(N=100). Subjective distress was assessed by visual analog scales around 8 hours postoperatively. Trained nurses collected objective distress data through observation of subject's behavior and vital signs. Data were analyzed with frequencies, percentages, means, Pearson correlation coefficients, ANOVA, and the Scheffe post test using SPSS/PC 11.0. Result: Subjective distress, objective distress, and state anxiety scores were relatively low, except pain scores(5.31 out of 10.0) among sub-scales of subjective distress. Women who had a total abdominal hysterectomy showed significantly higher levels of both subjective distress and state anxiety than those after a minor gynecologic surgery. In relationships among variables, subjective distress correlated positively with postoperative state anxiety, but not with the amount of analgesic medication, verified by further analysis on sub-scales of subjective and objective distress. The higher the levels of state anxiety, the higher the levels of tension, dyspnea, facial change, and systolic blood pressure observed. Conclusion: Regardless of effective pain management, most postoperatively experienced distress in gynecological patients was derived from surgery associated anxiety and pain. Specific psychological strategies should be established as well for those with high levels of state anxiety to facilitate prompt recovery.
Purpose: To investigate the effectiveness and variance of a critical pathway (CP) for laparoscopic colon resection in colon cancer patients, and nurses'satisfaction with the CP. Methods: A CP for laparoscopic colon resection was applied to the CP-group that included 50 patients, who underwent elective colon resection between March and May, 2011. The non-CP group included 51 patients who had the same operation without the CP applied from March to May, 2010. Results: The means of length of hospital stay were 11.7 and 7.3 days (p<.001) and the lengths of postoperative hospital stay were 8.6 and 5.1 days (p<.001) in the non-CP group and CP group, respectively. There was no significant difference between two groups for total healthcare costs, pain score, complications, or emergency room visits within 30 days after discharge. By examining variances of the CP, there were 162 variances and the most frequent cause was patient's condition. Nurses'satisfaction with the use of CP was favorable and the mean score of satisfaction was 3.76 on the 5 point Likert scale. Conclusion: There are clear benefits to use of CP, resulting in standardized and effective patient care. In conclusion, analysis of variance data can assist in evaluating and revising CP for optimal care and reducing variances.
Background: To assess the accuracy of ultrasound in differentiating endometrioma from ovarian cancer and to describe pattern recognition for atypical endometriomas mimicking ovarian cancers. Materials and Methods: Patients scheduled for elective surgery for adnexal masses were sonographically evaluated for endometrioma within 24 hours of surgery. All examinations were performed by the same experienced sonographer, who had no any information of the patients, to differentiate between endometriomas and non-endometriomas using a simple rule (classic ground-glass appearance) and subjective impression (pattern recognition). The final diagnosis as a gold standard relied on either pathological or post-operative findings. Results: Of 638 patients available for analysis, 146 were proven to be endometriomas. Of them, the simple rule and subjective impression could sonographically detect endometriomas with sensitivities of 64.4% (94/146) and 89.7% (131/146), respectively. Of 52 endometriomas with false negative tests by the simple rule, 13 were predicted as benign masses and 39 were mistaken for malignancy. Solid masses and papillary projections were the most common forms mimicking ovarian cancer, consisting of 38.5% of the missed diagnoses. However, with pattern recognition (subjective impression), 32 from 39 cases mimicking ovarian cancer were correctly predicted for endometriomas. All endometriomas subjectively predicted for ovarian malignancy were associated with high vascularization in the solid masses. Conclusions: Pattern recognition of endometriomas by subjective assessment had a higher sensitivity than the simple rule in characterization of endometriomas. Most endometriomas mimicking ovarian malignancy could be correctly predicted by subjective impression based on familiarity of pattern recognition.
Continuous epidural pain block with a local anesthetic agents is a commonly employed technique for pain relief after thoracotomy. In this study, we evaluated the effectiveness of the continuous epidural pain block in 19 patients undergoing elective lateral or posterolatrral thoracotomy with control group(n=19) from November 1994 to July 1995, Epidural lidocaine and morphine mixtures were injected via an epidural catheter as a bolus after operation, and then bupivacaine and morphine mixtures were injected continuously following 5 or 6 days. The pain score, upper arm elevation(ROM score), and respiratory rate were significantly changed(P<0.05) from 30min after injection. The CO2 tension of arterial blood was decreased significantly(P<0.05) from 2hr after injection. The postoperative hospital days were decreased significantly(P<0.05). Side effects of the epidural pain block were urinary retention(n= 10), urticaria(n=2) and a case of headache. There was no postoperative lung atelectasis. We conclude that the continuous epidural pain block is good for prevention of the postoperative lung complication and early recovery after thoracotomy.
Sixty-nine patients with various types of cyanotic congenital heart disease underwent systemic-pulmonary artery shunts with a microporous polytetrafluoroethylene [PTFE] prosthesis between 1979 and 1985. Their ages ranged from 2 months to 39 years [mean$\pm$SD: 5.2$\pm$7.4, median: 3.3 years]. Diagnosis included the following: Tetralogy of Fallot, 45: Double outlet right or left ventricle, 11: Single ventricle, .5: Transposition of great vessels, 4: Tricuspid atresia, 3 and Pulmonary atresia with intact ventricular septum, 1. Forty-eight patients had subclavian-pulmonary artery anastomosis, 12 patients aorta-right pulmonary artery anastomosis, 6 patients aorta-main pulmonary artery anastomosis, and 3 patients descending aorta-pulmonary artery anastomosis. The PTEE graft of 3 mm in diameter was used in 1, 4 mm in 29, 5 mm in 35 and 6 mm in 4 patients. Ten patients were died within 30 days after operation [mortality rate: 14.5%]. Among them, 6 patients were operated in urgency due to cardiac arrest or severe anoxic spell after cardiac catheterization, and so surgical mortality of elective operation is 9.5%. The 59 survivors showed improvement of the arterial oxygen saturation [65.4% - 9.8%] and hemoglobin [18.8 gm/dl - 16.0 gm/dl] values [V<0.01]. The follow up period ranged from 1 month to 67 months, [752 patient-months] and during this periods there were 4 late shunt failures after 3 months postoperatively with 4 mm graft, and 2 with 5 mm graft. The over-all patency rate of 4 mm PTFE was 85.9$\pm$9.2% [SEM] in 12 months and 40.9$\pm$22.5% in 24 months. The over-all patency rate of 5 mm PTFE was 87.5$\pm$9.6% in 12 months and 58.3$\pm$24.6% in 36 months. The lowest systolic pressure in death group was 64.9$\pm$15.0 mmHg and in survival group, 86.4$\pm$12.1 mmHg [P<0.001]. We think that the PTFE graft is useful in palliative shunt operation, but the effectiveness of the 4 mm PTFE graft may be limited. The blood pressure also may play an important role in patency of Prosthesis.

Purpose: This study analysed the intention of medical students career choice, educational programmes, and mentoring and counseling system for career planning at Yonsei medical school in Korea. Methods: The data were collected based on four separate graduation questionnaires at Yonsei medical school in the years of 2005, 2006, 2007, and 2008. The number of the survey was 130 in 2005, 130 in 2006, 153 in 2007, and that of the latest was 120 in 2008. We analysed the career intention on medical specialties and activities, and perceptions of important factors in choosing medical specialty. Results : The results which can be drawn from this study are these: firstly. students had more intention for choosing clinical medicine as university faculty than any other activities. While male students preferred to major in surgery, neurosurgery, orthopedic surgery, urology, otorhinolaryngology, female students in internal medicine, neurology, anesthesiology and pain medicine, diagnostic radiology, laboratory medicine. Secondly, students perceived that the most important factor which can influence on choosing a medical specialty was individual factor such as one's interests and concerns, values, and aptitudes. In stead, they relatively less perceived mentor and role model's effects on choosing a medical specialty compared to those of the United States of America. Third, the career planning at Yonsei medical school was evaluated well, especially educational programmes for career planning such as self assessment programme, elective(specialized) courses, and conversation with a senior programme. Conclusions: Unexpectedly, there are high demands for career planning by medical students. Therefore, we will reorganize systematic devices for career planning such as mentoring and counseling system at medical school.

Antithrombotic agents, including antiplatelet agents and anticoagulants, are widely used in Korea because of the increasing incidence of cardiocerebrovascular disease and the aging population. The management of patients using antithrombotic agents during endoscopic procedures is an important clinical challenge. The clinical practice guidelines for this issue, developed by the Korean Society of Gastrointestinal Endoscopy, were published in 2020. However, new evidence on the use of dual antiplatelet therapy and direct anticoagulant management has emerged, and revised guidelines have been issued in the United States and Europe. Accordingly, the previous guidelines were revised. Cardiologists were part of the group that developed the guideline, and the recommendations went through a consensus-reaching process among international experts. This guideline presents 14 recommendations made based on the Grading of Recommendations, Assessment, Development, and Evaluation methodology and was reviewed by multidisciplinary experts. These guidelines provide useful information that can assist endoscopists in the management of patients receiving antithrombotic agents who require diagnostic and elective therapeutic endoscopy. It will be revised as necessary to cover changes in technology, evidence, or other aspects of clinical practice.
Inguinal hernia is the most common disease treated by the pediatric surgeon. There are several controversial aspects of management 1)the optimal timing of surgical repair, especially for preterm babies, 2)contralateral groin exploration during repair of a clinically unilateral hernia, 3)use of laparoscope in contralateral groin exploration, 4)timing of surgical repair of cord hydrocele, 5)perioperative pain control, 6)perioperative management of anemia. In this survey, we attempted to determine the approach of members of KAPS to these aspects of hernia treatment. A questionnaire by e-mail or FAX was sent to all members. The content of the questionnaire were adapted from the "American Academy of Pediatrics (AAP) Section on Surgery hernia survey revisited (J Pediatr Surg 40, 1009-1014, 2005)". For full-term male baby, most surgeons (85.7 %) perform an elective operation as soon as diagnosis was made. For reducible hernia found in ex-preterm infants already discharged from the neonatal intensive care unit (NICU), 76.2 % of surgeons performed an elective repair under general anesthesia (85.8 %). 42.9 % of the surgeons performed the repair just before discharge. For same-day surgery for the ex-premature baby, the opinion was evenly divided. For an inguinal hernia with a contralateral undescended testis in a preterm baby, 61.9 % of surgeons choose to 'wait and see' until 12 month of age. The most important consideration in deciding the timing of surgery of inguinal hernia in preterm baby was the existence of bronchopulmonary dysplasia (82.4 %), episode of apnea/bradycardia on home monitoring (70.6 %). Most surgeons do not explore the contralateral groin during unilateral hernia repair. Laparoscope has not been tried. Most surgeons do not give perioperative analgesics or blood transfusion.
