Background: Bullectomy through a transaxillary minithoracotomy have been widely used in the treatment of primary spontaneous pneumothorax. Material and Method: From September 1997 to September 1998, 22 consecutive cases of those who underwent transaxillary mini thoracotomy with Finochieto rib spreader(group F) and 24 consecutive cases with Naruke thoraco-opener(group N) at Taegu Fatima Hospital were reviewed retrospectively to compare the clinical results of transaxillary minithoracotomy with different rib spreaders in the opera tive treatments of primary spontaneous pneumothorax. Result: There were no significant differences in operative time, hospital stay, postoperative hospital stay, the duration of the indwelling chest tube, and the number of postoperative recurrences and complications in the two group. CONCLUSION This technique may be useful in the operative treatments of primary spontaneous pneumothorax.
Purpose: The purposes of the study were 1) to examine what relationships exist between PTE(perceived treatments effect) and PPS (perceived physical suffering) as the independent variables and hope as the dependent variable and 2) to examine whether PTE and PPS predict hope in cancer patients in their post-operative period within the Stotland's hope theory. Method: The Visual Analog Scale was used for measuring PTE and PPS and the Kim & Lee's Hope Scale which had acceptable reliability and validity was used for measuring hope. The data was collected from 38 hospitalized cancer patients who were in the post-operative period with a convenient sampling method. Result: There was a significant positive relationship between hope and the PTE in the low PTE group. There was a significant negative relationship between hope and the PPS in the low PPS group. There were no significant relationships between hope and the PTE in the high PTE group, and between hope and the PPS in the high PPS group. And the PTE explained hope with 71.2% of the variance in the low PTE group. Conclusion: PTE in the low PTE group and PPS in the low PPS group were identified as the factors to explain hope.

Purpose: Clinical characteristics and medical cost were analyzed according to the surgical procedures for intertrochanteric fracture in aged patients to assess the appropriateness of treatment expense and to find possibility of reducing the medical cost. Method: Variable for the statistical analysis were; the clinical characteristics, medical cost according to the surgical procedures, the treatment success rate, the total medical expense, and the average expense per case. SAS Package Version 8.02. was used to analyze the relevant data. Results: Operative procedures differ significantly according to the gender and by the location of institution. Only significant clinical variables according to the operative procedure were duration of general anesthesia and amount of blood transfusion. Average cost per treatment was the highest in the bipolar hemiarthroplasty followed by the gamma nail and hip compressing screw. Average cost for bipolar hemiarthroplasty was significantly higher than other surgical procedures. Conclusions: The difference in hospital costs for treatment of intertrochanteric fracture originates from the utilized surgical procedures, mostly by the materials used. The method of surgical treatment should be carefully determined by the purpose of the surgery, in order to improve the quality of medical care and also to reduce the hospital cost.
Traumatic aortic transection after blunt chest injury is highly lethal and has high operative mortality. Recently, the diagnostic and therapeutic method of this injury is advanced, especially in spinal cord protection during aortic cross-clamping. We have experienced two cases of traumatic aortic transection with left hemothorax after blunt chest injury, which was diagnosed in operative field. The transected aorta was primarily repaired with clamp and sew method and postoperative paraplegia had not occured. The patients were dischraged without any significant complications. We report these cases with a review of literature.

Purpose: This study was performed to evaluate and compare the radiopacity of dentin, enamel, and 8 restorative composites on conventional radiograph and digital images with different resolutions. Materials and Methods: Specimens were fabricated from 8 materials and human molars were longitudinally sectioned 1.0 mm thick to include both enamel and dentin. The specimens and tooth sections were imaged by conventional radiograph using #4 sized intraoral film and digital images were taken in high speed and high resolution modes using a phosphor storage plate. Densitometric evaluation of the enamel, dentin, restorative materials, a lead sheet, and an aluminum step wedge was performed on the radiographic images. For the evaluation, the Al equivalent (mm) for each material was calculated. The data were analyzed using one-way ANOVA and Tukey's test (p<0.05), considering the material factor and then the radiographic method factor, individually. Results: The high speed mode allowed the highest radiopacity, while the high resolution mode generated the lowest values. Furthermore, the high resolution mode was the most efficient method for radiographic differentiation between restorative composites and dentin. The conventional radiograph was the most effective in enabling differentiation between enamel and composites. The high speed mode was the least effective in enabling radiographic differentiation between the dental tissues and restorative composites. Conclusion: The high speed mode of digital imaging was not effective for differentiation between enamel and composites. This made it less effective than the high resolution mode and conventional radiographs. All of the composites evaluated showed radiopacity values that fit the ISO 4049 recommendations.
The purpose of this study was to evaluate and compare the sealing ability of ZOE, FR and Sealapex, as a root canal sealer. Ninety six extracted anterior or premolar human teeth with single root were instrumented by using conventional method. After instrumentation, the teeth were divided into three groups and thirty two teeth in each group were filled as follows: ZOE group: ZOE cement as a root canal sealer in combination with guttapercha cone FR group: FR root canal sealer in combination with guttapercha cone Sealapex group: Sealapex root canal sealer in combination with guttapercha cone $^{45}Ca$ in the form of calcium chloride, was employed as the tracer in this study and produce the auto-radiograph. The depth of isotope penetration into the root canal was evaluated by method by Yates and Hembree at the intervals of 1 day, 7 days, 14 days and 30 days. The following conclusions were derived from the results obtained; 1. After 1 day, ZOE group exhibited the greatest penetration degree of radioisotope (p < 0.05). 2. After 14 days, there was some difference of the radioisotope penetration between each group, but its difference was not significant statistically. 3. After 30 days Sealapex group exhibited the least penetration degree of radioisotope (p < 0.025). 4. In ZOE and Sealapex groups, there was no change of the degree of radioisotope penetration with time.
Anatomic correction of the transposition of the great arteries (TGA) or Taussig-Bing anomaly by means of the arterial switch operation is now accepted as the therapeutic method of choice. This retrospective study was conducted to evaluate the risk factors for operative deaths and the efficacy of technical modification of the coronary transfer. 85 arterial switch operations for TGA or Taussig-Bing anomaly which were performed by one surgeon from 1994 to July 2002 at Dong-A university hospital were included in this retrospective study Multivariate analysis of perioperative variables for operative mortality including technical modification of the coronary transfer was peformed. Overall postoperative hospital mortality was 20.0% (17/85). The mortality before 1998 was 31.0% (13/42), but reduced to 9.3% (4/43) from 1998. The mortality in the patients with arch anomaly was 61.5% (8/13), but 12.5% (9/72) in those without arch anomaly. In patients who underwent an open coronary reimplantation technique, the operative mortality was 28.1% (18/64), but 4.8% (1/21) in patients undergoing a technique of reimplantation coronary buttons after neoarotic reconstruction. Risk factors for operative death from multivariated analysis were cardiopulmonary bypass time ($\geq$ 250 minutes), aortic cross-clamping time ($\geq$ 150 minutes), aortic arch anomaly, preoperative event, and open coronary reimplantation technique. Operative mortality has been reduced with time. Aortic arch anomaly and preoperative events were important risk factors for postoperative mortality. However atypical coronary artery patterns did not work as risk factors. We think that the technical modification of coronary artery transfer played an important role in reducing the postoperative mortality of arterial switch operation.
Objective: The purpose of this study was to determine breast shape and ratio of breast enlargement women prior to development of breast enlargement patient's bra. Background: Although there are many previous studies on women's breast that did not undergo breast augmentation surgery, no studies have examined the breast type and proportion of women with breast augmentation. Method: In this study, we analyzed ratios and angles with photographs taken before and after breast augmentation on the frontal and lateral views of the breast, UPF and projection were analyzed too. We also compared the pre-operative and post-operative rates with those of previous breast studies, as well as the post-operative breast types for the desirable breast types. Results: The length and width of the breast base and the height of the breast projection increased after the operation. The rate of increase in width is larger than the vertical distance in the breast base, and the rate of increase in height of the projection is larger than the increase in the width. Specifically, in the vertical distance, the rate of increase in the lower portion is larger than that in the upper portion. In the width, the rate of increase on the inside is larger than that on the outside. Conclusion: The angles of the static relationship with the projection increased and the angles of the minor relation decreased. The changes in the size of the breast were visually observed in the overlapping of the triangle shape before and after the surgery. The changes were composed of the line connecting the angle and the measurement points. The pre-operative upper pole fullness (UPF) was mostly 0 and - 1, but after the surgery, +1, 0, -1, +2 were distributed, while post-operative levels of projection were distributed in the order of level 3> level 1> level 2. In comparison with the desirable breast type, it was found that the anatomical type was a more natural breast type than the round type of implant. Application: These results can be useful as basic data for the breast analysis of breast enlargement patients and their bra patterns.
Purpose : There has been considerable controversy as to the method of the treatment of acute acromioclavicular joint dislocation classified to type III injury. The purpose of this study is to compare the conservative and operative treatment of the type III acute acromioclavicular joint dislocation in terms of clinical and radiological results. Materials and Methods: We treated 31 cases of acute, type III acromioclavicular joint dislocation, 17 cases were treated by operative methods and 14 patients by conservative treatment, and 1 year minimum follow-up was done from January 1990 to January 1996. We used UCLA Shoulder Rating Scale for clinical results. And for the radiological results coracoclaviclar distance were measured. We used Fisher's exact test for statistical analysis of results between the two treatment methods. Results: Fifteen(88.2%) of seventeen patients in operative treatment and eleven(78.6%) of fourteen patients in nonoperative treatment were rated excellent or good on the UCLA rating scale. In radiographic evaluation, the average coracoclavicular distances of preoperative state, immediate postoperation(or postreduction) and last follow-up were as follows. In operative cases, it was 1.75±0.21mm, 1.14±0.24mm and 1.33± 0.22mm respectively. In nonoperative cases, it was 1.65±0.14mm, 1.26±0.26mm, and 1.42±0.27mm respectively. Conclusion : This study demonstrated that there was no significant difference in clinical and radiological results between the operative and nonoperative treatment groups. So, nonoperative treatment is recommended for acute type III acromioclavicular dislocation as general rule.
Purpose: It is hypothesized that robotic gastrectomy may surpass laparoscopic gastrectomy after the operators acquire long-term experience and skills in the manipulation of robotic arms. This study aimed to evaluate the long-term learning curve of robotic distal gastrectomy (RDG) for gastric cancer compared with laparoscopic distal gastrectomy (LDG). Materials and Methods: From October 2008 to December 2015, patients who underwent LDG (n=809) were matched to patients who underwent RDG (n=232) at a 1:1 ratio, by using a propensity score matching method after stratification for the operative year. The surgical outcomes, such as trends of operative time, blood loss, and complication rate, were compared between the two groups. Results: The RDG group showed a longer operative time (171.3 minutes vs. 147.6 minutes, P<0.001) but less estimated blood loss (77.6 ml vs. 116.6 ml, P<0.001). The complication rate and postoperative recovery did not differ between the two groups. The RDG group showed a longer operative time and similar estimated blood loss compared with the LDG group after 5 years of experience (operative time: 159.2 minutes vs. 136.0 minutes in 2015, P=0.003; estimated blood loss: 72.9 ml vs. 78.1 ml in 2015, P=0.793). Conclusions: In terms of short-term surgical outcomes, RDG may not surpass LDG after a long-term experience with the technique.
