Pediatric laparoscopic splenectomy has been gradually accepted as the surgical management of a various splenic disorders, particularly in hematologic diseases. We report our experience with 16 patients who underwent this procedure because of hematologic disorders during the past 3 and a half years at the Department of Surgery, St. Mary's Hospital, the Catholic University Medical College. The mean age was 10 years(range 6-16 years) and the mean spleen weight was 210 gm(range 85-500 g). The indication for splenectomy were hereditary spherocytosis(6 cases), idiopathic thrombocytopenic purpura(8 cases), autoimmune hemolytic anemia(1 case), and idiopathic splenomegaly(1 case). All splenectomies were performed safely with mean estimated blood loss of 233 ml. Mean operative time and mean postoperative hospital stay were 157 min and 4.5 days, respectively. Postoperative pain, medication was needed in 3 cases, just one injection in immediate postoperative period. Diet was started on the second or third postoperative day. In conclusion, laparoscopic splenectomy in pediatric patients is a safe procedure, offering a small of abdominal scar, much less pain, a shorter hospital stay and car the lower postoperative morbidity.

Background: this study was designed to estimate whether specific risk factors could increase the postoperative complication rate of pneumonectomy for chronic complicated inf-lammatory lung disease. Material and Method: Eighty-five patients underwent pneumon-ectomy for chronic complicated inflammatory lung disease(tuberculosis, 67 ; bronchiecasis 11; aspergio- losis, 4; others, 3) between January 1991 and August 1998. We performed a univariated statistical analysis to identify preoperative and intraoperative risk factors associated with postoperative complications, Result: There was no operative mortality. There were a total of 18 postoperative complications(22.2%) Bronchopleural fistula(BPF) and empyema occurred in 5(5.9%) and 2(2.4%) respectively. General complication rate was significantly higher in patients with right-sided pneumonectomy(p=.029) extrapleural pneu-monectomy(p=.009) and intraoperative pleural spillage due to cavity or lesion perforation (p=.004). The prevalence of BPF and empyema was higher in patients with right sided pneumonectomy(p=.007) extrapleural pneumonectomy(p=.015) and intraoperative pl- eural spillage due to cavity or lesion perforation(p=.003) which is as the same results as gen-eral complication rate. Conclusion: The postoperative complication rate of pneumone-ctomy for chronic complicated lung disease is accptably low. But it is increase in patients with right sided pneumonectomy extrapleural pneumonectomy and intraoperative pleural spillage due to cavity or lesion perforation. therefore more careful and meticulous intra-operatve management are needed in right sided extrapleural pneumonectomy without intra- pleural spillage.

Background: Packing after closed reduction of nasal fracture causes uncomfortable nasal obstruction in patients. We packed the superior meatus with synthetic polyurethane foam (SPF) to support the nasal bone, and packed the middle nasal meatus with a nasal airway splint (NAS) and SPF. The aim of this article is prospectively to compare the subjective patient discomfort of SPF (Nasopore Forte plus) packing alone and SPF with NAS. Methods: We compared the prospectively subjective patient discomfort of SPF packing alone (group A) and SPF with NAS (group B) via visual analog scale (VAS; 0, no symptom; 100, most severe symptom). Results: At first postoperative day group B showed significant lower scores in dry mouth, sleep disturbance, conversation difficulty. However at third postoperative day, VAS scores of each group had no statistically significant differences. Moreover at fifth postoperative day group A had statistically significant lower scores for nasal pain, dry mouth than the group B. Conclusion: Combination method of using NAS and SPF have some advantage on the patient comfort from first postoperative day to third postoperative day.

Purpose: Microtia is a congenital anomaly resulting from abnormal development of the branchial apparatus. Although significant modification and improvement of operative procedures for the reconstruction of the auricle with a natural appearance have been reported, postoperative complications, such as infection, flap necrosis and deformity, still remain serious problems in patients. Many studies with long-term results have focused mainly on operative procedures for an acceptable auricular shape without consideration of possible complications. Methods: We conducted a retrospective study on postoperative complications at the recipient sites of 183 patients who underwent auricular reconstruction with autologous rib cartilage grafts from November 1987 to January 2007 at the Division of Pediatric Plastic Surgery, Seoul National University Children's Hospital. Patients were analyzed in terms of the kinds and incidences of complications, and their treatment options. Results: Postoperative complications included wound dehiscence, flap necrosis, infection, hypertrophic scar, auricular deformity and absorption of rib cartilage grafts. The complications occurred in 47 patients with a complication rate of 25.7%. Fourteen patients were successfully managed with conservative treatment. However, surgical treatment was required in 51 reoperations(33 patients) of total 329 operations. Conclusion: Postoperative complications at the recipient sites of autologous rib cartilage grafts occurred with relatively high incidences and required long-term treatments and multiple surgeries. The results of this study may provide information on the causes and proper management of postoperative complications as well as safe procedures for the reconstruction of the auricle.

Background: Pregabalin has been studied as a single or multimodal analgesic drug for postoperative pain management in different types of surgeries. We evaluated the analgesic effect of 150 mg of pregabalin in resolving post-gastrectomy pain. Methods: Forty-four patients were randomized into two groups: a pregabalin group that received oral pregabalin (150 mg) 2 h before anesthetic induction, and a control group that received placebo tablets at the same time. Data on postoperative pain intensity (visual analog scale [VAS], at 30 min, 2 h, 4 h, and 24 h), consumption of fentanyl in patient-controlled analgesia (PCA), and the proportion of patients requiring rescue analgesics at different time intervals (0-2 h, 2-4 h, and 4-24 h) were collected during the 24 h postoperative period. Results: The VAS scores did not show significant differences at any time point and consumption of fentanyl in PCA and the proportion of patients requiring rescue analgesics did not differ between the two groups. The groups did not differ in the occurrence of dizziness, sedation, and dry mouth. Conclusion: A preoperative 150 mg dose of pregabalin exerts no effect on acute pain after gastrectomy.

Background: Quality of postoperative care may be improved by management of postoperative pain. Epidural anesthesia and analgesia have several advantages over general anesthesia and parenteral analgesics in managing the postoperative pain. We retrospectively reviewed records of obstetrical patients who underwent the cesarean sections under epidural anesthesia to evaluate perioperative analgesic use, side effects, and complications. Methods: All patients received epidural anesthesia consisting of 0.25% bupivacaine, 2% lidocaine and 100 ${\mu}g$ fentanyl, followed by epidural analgesia with 0.1% bupivacaine and 12.5 ${\mu}g$/ml fentanyl at rate of 2 ml/hr for 48 hours. Patients' records were reviewed for: medications administered for pain relief, incidence of nausea and vomiting and pruritus, and presence of respiratory or cardiovascular depression. Results: Over 18 months, 1,054 patients' records were reviewed. Average age was 27.8 years (18~43 years). 768 patients (72.9%) received no additional drugs for the pain relief. Intramuscular analgesics, ketoprofens, were one time administered to 247 patients (23.4%), 39 patients (3.7%) received two more dosages. The time of administration was $8.3{\pm}4.3$ hours postoperatively. Antiemetics, for example, low-dose droperidol, were administerd one time for 160 patients (15.2%), 5 patients (0.5%) received two or more administrations. The medication was administered $5.1{\pm}4.2$ hours postoperatively. Drugs for relief of pruritus, low-dose naloxone, were administered one time for 108 patients (10.2%), 10 patients (0.9%) received 2 or more dosages. The time of administration was $6.3{\pm}4.2$ hours postoperatively. None of the patients experienced cardiovascular nor respiratory (<8 breath/min) depression. Conclusions: Postoperative continuous epidural analgesia in combination with bupivacaine and fentanyl is an effective method of providing postoperative analgesia with low incidence of side effects.
