Ulcerative colitis, an inflammatory bowel disease, is primarily managed medically with a combination of 5-ASA and steroids. However, this chronic disease requires surgical management if symptoms persist or complications develop despite medical management. The clinical course, indications and outcome of surgical management of 21 patients under the age of 15 who were endoscopically diagnosed with ulcerative colitis at the Seoul National University Children's Hospital between January, 1988 and January, 2003 were reviewed. Mean follow up period was 3 years and 10 months. The mean age was 10.3 years old. All patients received medical management after diagnosis and 8 patients (38 %) eventually required surgical management. Of 13 patients who received medical management only, 7 patients (53 %) showed remission, 4 patients are still on medical management, and 2 patients expired due to congenital immune deficiency and hepatic failure as a result of sclerosing cholangitis. In 8 patients who received surgical management, the indications for operation were, 1 patient sigmoid colon perforation and 7 patients intractability despite medical management. The perforated case had a segmental colon resection and the other 7 patients underwent total colectomy with ileal pouch-anal anastomosis. One patient expired postoperatively due to pneumonia and sepsis. and 1 is still on medical management because of mild persistent hematochezia after surgery. Six other operated patients are doing well without medical therapy. Pediatric ulcerative colitis patients can be surgically managed if the patient is intractable to medical management or if complications such as perforation are present. Total colectomy & ileal pouch-anal anastomosis is thought to be the adequate surgical method.

Purpose: Supraventricular arrhythmia is a well-known complication of cardiothoracic surgery, and is common in patients wirth underlying cardiovascular disease. Also, it's treatment and prognosis are well known. However the incidence, the contributing factors, and the prognosis for supraventricular arrhythmias in noncardiothoracic surgical patients are less well known. This study was undertaken to investigate the incidence, the clinical presentation, the prognosis, and the factors comtributing to the prognosis for supraventricular arrhythmia in the surgical intensive care unit. Methods: We performed a retrospective study of 34 patients with newly developed or aggravated supraventricular arrhythmias in the surgical intensive care unit between March 2004 and February 2005. The incidence, the risk factors, and the prognosis of supraventricular arrhythmias were analyzed. Results: During a 12month period, the incidence of supraventricular arrhythmia was 1.79% (34/1896). Most patients had pre-existing cardiovascular disease and sepsis. The mortality rate was 29.4%, and the most common cause of death was multiple organ failure due to septic shock. The mean value of the APACHE II score was 20.9, and the surgical intensive care unit and the hospital lengths of stay were 9.9 days and 25.8 days, respectively. The APACHE II score measured when the arrhythmia developed was a significant factor in predicting mortality, Conclusion: Supraventricular arrhythmias result in increased mortality and increased length of stay in both the surgical intensive care unit and the hospital. The arrhythmia itself did not cause death, but a high APACHE II score incicated a poor prognosis. This may reflect the severity of the illness rather than an independent contributor to mortality.

Objective: The number of three-piece maxillary osteotomies has increased over the years; however, the literature remains controversial. The objective of this study was to evaluate the skeletal stability of this surgical modality compared with that of one-piece maxillary osteotomy. Methods: This retrospective cohort study included 39 individuals who underwent Le Fort I maxillary osteotomies and were divided into two groups: group 1 (three pieces, n = 22) and group 2 (one piece, n = 17). Three cone-beam computed tomography scans from each patient (T1, pre-surgical; T2, post-surgical; and T3, follow-up) were used to evaluate the three-dimensional skeletal changes. Results: The differences within groups were statistically significant only for group 1 in terms of surgical changes (T2-T1) with a mean difference in the canine region of 3.09 mm and the posterior region of 3.08 mm. No significant differences in surgical stability were identified between or within the groups. The mean values of the differences between groups were 0.05 mm (posterior region) and -0.39 mm (canine region). Conclusions: Our findings suggest that one- and three-piece maxillary osteotomies result in similar post-surgical skeletal stability.

Total 310 cases of spontaneous pneumothorax in 281 patients were analyzed to review the results of surgical treatment for this condition. Clinical data on the age & sex distribution, recurrence, etiologic conditions and on the other aspects of spontaneous neumothorax were summarized. The results of surgical management of spontaneous pneumothorax are followings; 205 out of 310 cases[66.1%] were cured by closed thoracostomies. 82 cases[26.5%] were cured by thoracotomy. The indications of thoracotomy were 1] persistent air leakage, 2] history of recurrences, 3] blebs or bullae on thoracoscopy, 4] associated parenchymal lesion, 5] pneumothorax caused by paragonimiasis. Other reasons of thoracotomy were bilateral pneumothorax and inadequate expansion due to chronicity. Excision of blebs or wedge resection was performed in most cases with good result. Lobectomy [9 case] or pneumonectomy [3 cases] was carried out depending on the pathological involvement of the lung. There was no operative death and only one case showed recurrent pneumothorax during follow-up after thoracotomy.

This paper deals with the designing of instrument for achieving surgical operation in the stomach and gullet using endoscope channel. The method used herein was to provide beads to knot suturing thread automatically. Following design rules were applied : 1) that instrument must be designed to enable surgical operator to stitch successively by only simple handling 2) that instrument must be designed to minimize insertion and extraction of endoscope. The main result from the experiment with animal stomach was that the surgical operation time was reduced and successive suture was available. Considering the requirement of operator‘s highly trained skills and the discomfort of patient in traditional suture process, the proposed design is expected to markedly improve the endoscopic suturing performance.

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade. Herein we report a case of the embolism of a device into the pulmonary artery after one hour of percutaneous closure in which the embolized device was surgically removed and the defect was closed with a pericardial patch.
