Vidio-assisted thoracic surgery[VATS] has recently evolved as an alternative to thoracotomy for several thoracic disorders,and the role of thoracoscopy has expanded with advances in surgical techniques and instruments. From May 1993 to May 1994, 13 patients with mediastinal mass underwent VATS for diagnosis and treatment at Gil General Hospital. There were four males and nine females, and their ages raged from 5 years to 66 years with average 38.8 years. Among 13 patients, 3 were operated for tissue diagnosis,9 for treatment,and 1 for diagnosis and treatment. Pathologic diagnoses were as follows; 5 benign neurogenic tumors, 2 thymoma, 2 sarcoidosis, 1 teratoma, 1 peripheral neuroepithelioma, 1 tbc lymphadenitis, and 1 pericardial cyst. The mean time of operation was 111.7 $\pm$ 30.7 minutes[60-160], mean duration of chest tube drainage was 2.9 $\pm$1.9days[1-9], mean hospital stay was 6.2 $\pm$2.6 days[4-13]. There was no patient needed blood transfusion or conversion to open thoracotomy. Accurate diagnosis was possible in all patients operated for diagnosis and /or treatment.[4/4,100%] Two complications occurred in two patients: 1 transient Horner,s syndrome,1 anhydrosis of left arm. Compared with those of conventional thoracotomy done for mediastinal mass during previous 2 years[May 1991 - April 1993], operative results of VATS were better in all aspects. For mediastinal mass, we concluded that VATS can be done with less morbidity,less complication,less blood loss,shorter operation time and hospital stay,and not more expensive in cost than conventional thoracotomy. Noticeably, we think that VATS is the operation of choice for the diagnosis and palliation of malignant mediastinal mass.

The laparoscopic splenectomy (LS) became popular over the last 10 years. The advantage of LS over open splenectomy (OS) includes short hospital stay, improved cosmesis, less development of postoperative intestinal ileus, and less analgesics required. The purpose of this study is to evaluate the outcome of LS at Asan Medical Center from January 1999 to January 2003. The records of 14 consequent children who underwent splenectomy were reviewed retrospectively. Patients characteristics, morbidity, mortality, operative time, blood loss, and hospital stay were analyzed., Seven patients age 5 to 15 years underwent LS under the indications: idiopathic thrombocytic purpura (ITP, n=3), hereditary spherocytosis (n=3), and myelodysplastic syndrome (n=l). Seven patients, age 7 to 16 years, underwent OS during the same period for ITP (n=7). Median operative time was 120 mInutes (80 to 170 mins.) in OS, and 270 minutes (110 to 480 mins,) in LS (p<0.05). Median length of hospital stay was 6 days (3 to 8) in OS, and 4 days (3 to 6) in LS (p>0.05). Median splenic length was 12.0cm (9.2 to 18.0) in OS, 14.0 cm (10.0 to 19.5) (p>0.05). Accessory spleens were identified in 3 of 7 LS and 1 of 7 OS cases. In the LS group, there was no conversion to open surgery. Two patients in LS required blood transfusion postoperatively. LS in children can be performed as effectively and safely as OS.

Background: Patient-controlled epidural analgesia (PCEA) is known to provide good postoperative analgesia in many types of surgery including laparoscopic surgery. However, no study has compared PCEA with patient-controlled intravascular analgesia (PCIA) in laparoscopic radical prostatectomy (LARP). In this study, the efficacy and side effects of PCEA and PCIA after LARP were compared. Methods: Forty patients undergoing LARP were randomly divided into two groups: 1) a PCEA group, treated with 0.2% ropivacaine 3 ml and 0.1 mg morphine in the bolus; and 2) a PCIA group, treated with oxycodone 1 mg and nefopam 1 mg in the bolus. After the operation, a blinded observer assessed estimated blood loss (EBL), added a dose of rocuronium, performed transfusion, and added analgesics. The numeric rating scale (NRS), infused PCA dose, and side effects were assessed at 1, 6, 24, and 48 h. Results: EBL, added rocuronium, and added analgesics in the PCEA group were less than those in the PCIA group. There were no significant differences in side-effects after the operation between the two groups. Patients were more satisfied with PCEA than with PCIA. The NRS and accumulated PCA count were lower in PCEA group. Conclusions: Combined thoracic epidural anesthesia could induce less blood loss during operations. PCEA showed better postoperative analgesia and greater patient satisfaction than PCIA. Thus, PCEA may be a more useful analgesic method than PICA after LARP.

Objective : Lumbar spinal stenosis is increasingly recognized as a common cause of low back pain in elderly patients. Conservative treatment has been initially applied to elderly patients, however, surgical treatment is sometimes indispensable to relieve severe pain. We retrospectively examine the age-related effects on the surgical risk, and results following general anesthesia and operative procedure in geriatric patients for two different age groups of at least 65years old. Methods : Consecutive 51 patients [${\ge}$ 65years], who underwent open surgical procedure for degenerative lumbar spinal stenosis, were selected in the study. Patients were divided into two groups. Group A included all patients who were between 65 and 69years of age at the time of surgery. Group B included all patients who were at least 70years of age at the time of surgery. We reviewed medical history including preoperative American Society of Anesthesiologists[ASA] classification of physical status, anesthetic risk factor, operative time, estimated blood loss, transfusion requirements, hospital stay, operated level, and clinical outcome to look for comparisons between two age groups [$65{\sim}69$ and over 70years]. Results : In preoperative evaluation, mean anesthetic risk factor of patients was numerically similar between the groups. The American Society of Anesthesiologists classification of physical status was similar between two groups. There was no difference in operated level, operative time, estimated blood loss, hospital stay, and anesthetic risk factor between the two groups. The clinical successful outcome showed 82.7% for Group A and 81.8% for group B. The overall postoperative complication rates were similar for both group A and B. Conclusion : We conclude that advanced age per se, did not increase the associated morbidity and mortality in surgical decompression for spinal stenosis.

The use of hemofiltration has been proposed to reduce excessive body fluid and inflammatory mediators produced during cardiac surgery with cardiopulmonary bypass (CPB) in infants and children. This study was undertaken to evaluate the efficacy of hemofiltration in adult cardiac surgery using (CPB). Twenty adult patients scheduled for elective cardiac surgery were randomly assigned to control group without hemofiltration (n=10) or hemofilter group with hemofiltration during CPB (n=lO). CBC and serum levels of interleukin-6 (IL-6), D-dimer, endothelin-l (ET-1), and cortisol were measured at before the initiation and immediately after the termination of CPB (Pre-CPB and End-CPB, respectively). Clinical data were assessed at postoperative period. In hemofilter group hematocrit was significantly higher (30.04±2.63％ vs 23.30±2.71％, P=0.0014) whereas total leukocyte count was lower than in control group (7.71±1.78×10³/㎣ vs 16.01 ±3.12x10³/㎣, P=0.021) at End-CPB. Increased rate of IL-6 (311.56±97.31％ vs 825.45±102.56％, P=0.012) and D-dimer levels (154.55±89.04％ vs 308.33±157.64％, P=0.026) at End-CPB were significantly less in hemofilter group than in control group. Postoperative blood transfusion in hemofilter group was low compared with that of control group (741.00±38.07 ml vs 1,137.50±169.82 ml, P=0.037). There were no significant differences between two groups in platelet count, ET -1, cortisol, pulmonary index, mechanical ventilation, postoperative blood loss, ICU-stay and hospitalization. Hemofiltration technique applied in the present study provided partly beneficial effect in adult cardiac surgery.

Background: The present study was conducted to evaluate the technical feasibility, safety and adequacy of surgical margins with salvage transoral robotic surgery (TORS) for recurrent or residual head and neck squamous cell carcinoma patients. Materials and Methods: Thirty patients who underwent salvage TORS using the 'DaVinci' robot were enrolled in the study and data related to their surgical time, complications and functional outcome were recorded. Results: The feasibility of salvage TORS in our study was observed to be 100%. Positive margins were encountered in only 6.7% of patients. Mean blood loss was 23.3 ml with no patient requiring blood transfusion. Postoperative complications in the form of primary haemorrhage requiring active surgical intervention occurred in 13.3%. Oral feeding could be started as early as the 3rd postoperative day in a few patients, with nasogastric tubes being removed on the 12th postoperative day. Long term gastrostomy tube dependency was seen in 10% cases. Median survival of patients was 19 months. Conclusions: Salvage TORS is a safe, effective and feasible option in the management of treatment failure cases. It offers an alternative surgical approach with unexpected benefits in terms of tracheostomy tube use, Ryle's tube and gastrostomy dependence.

Background: To determine surgical outcomes, perioperative complications, and patient outcomes in gynecologic cancer patients undergoing robotic surgery. Materials and Methods: Surgical outcomes, including docking time, total operative time, console time, estimated blood loss (EBL), conversion rate and perioperative complications were retrospectively reviewed in 30 gynecologic cancer patients undergoing robotic surgery. Patient outcomes included recovery time and patient satisfaction, as scored by a visual analogue scale (VAS) from 0-10. Results: The operations included 24 hysterectomies with pelvic lymphadenectomy (PLD) and/or para-aortic lymphadenectomy, four radical hysterectomies with PLD, and two radical trachelectomies with PLD. Mean docking time was $12.8{\pm}9.7min$, total operative time was $345.5{\pm}85.0min$, and console time was $281.9{\pm}78.6min$. These times were decreased in the second half of the cases. There was no conversion rate. Three intraoperative complications, including one external iliac artery injury, one bladder injury, and one massive bleeding requiring blood transfusion were reported. Postoperative complications occurred in eight patients, most were minor. Only one patient had port herniation that required reoperation. Mean hospital stay was $3.5{\pm}1.7days$, and recovery time was $14.2{\pm}8.1days$. Two-thirds of patients felt very satisfied and one-third felt satisfied; the mean satisfaction score was 9.4 +0.9. Two patients with stage III endometrial cancer developed isolated port site metastasis at five and 13 months postoperatively. Conclusions: Robotic surgery for gynecologic cancer appears to be feasible, with acceptable perioperative complication rate, fast recovery time and high patient satisfaction.

A 3-month-old intact male, Labrador retriever was presented with the history of coagulopathy and anemia. The results of initial screening tests of the hemostatic system yielded a tentative diagnosis of hemophilia. Activated partial thromboplastin time (APTT) was distinctly prolonged (106 seconds) and prothrombin time (PT) was not detected due to markedly prolonged test time. Whole blood transfusions (20 me l/kg body weight) were carried out prior to assays of coagulation factor. After transfusion, the patient recovered well and hemorrhage ceased. Blood samples were assessed for coagulation factor activity. The patient showed markedly low factor IX coagulation activity (5%, reference range: 7~140%) and was diagnosed with hemophilia B. After recovery, the patient was discharged from the hospital. However, 4 months later the patient was re-hospitalized for recurrence of the initial symptoms. The owner did not want to pursue further treatment and the patient died of respiratory distress two days later.

Purpose: This study was done to identify learning experiences and self-confidence and to analyze nursing students' self-confidence according to learning experiences for core nursing skills (CNS). Method: Participants were 502 final year nursing students. Data were collected using a structured questionnaire and analyzed using descriptive statistics and t-test. Results: Over 60% of participants had practiced 15 items of the 24 CNS in the basic nursing lab (BNL). In clinical practice (CP), they had practiced five items but experienced only one item in a simulation lab (SL). Items with the highest confidence level were vital signs (4.69) followed by blood sugar test (4.60), pulse oximeter (4.38), and oral medication (4.12). Items with the lowest confidence level were blood transfusion (2.17) followed by enema (2.64) and indwelling catheterization (2.67). The group with CNS experience in the practice curriculum was generally more confident than the group with no experience. Self-confidences in some skills was significantly different depending on availability of SL, credits for BNL and CP, and presence of preceptors. Conclusion: Results indicate a need to develop practice education strategies such as changing the CP to practice-centered learning with preceptors and including well-designed SL to increase confidence of nursing students.
