OBJECTIVE: Decompressive craniectomy (DC) is a useful surgical method to achieve adequate decompression in hypertensive intracranial patients. This study suggested a new skin incision for DC, and analyzed its efficacy and safety. METHODS: In the retrograde reviews, 15 patients underwent a newly suggested surgical approach using n-shape skin incision technique (Group A) and 23 patients were treated with conventional question mark skin incision technique (Group B). Two groups were compared in the terms of the decompressed area of the craniectomy, protruded brain volume out of the skull layer, the operation time from skin incision to bone flap removal, and modified Rankin Scale (mRS) which was evaluated for 3 months after surgery. RESULTS: The decompressed area of craniectomy (389.1 cm² vs. 318.7 cm², p=0.041) and the protruded brain volume (151.8 cm³ vs. 116.2 cm³, p=0.045) were significantly larger in Group A compared to the area and the volume in Group B. The time interval between skin incision and bone flap removal was much shorter in Group A (23.3 minutes vs. 29.5 minutes, p=0.013). But, the clinical results were similar between 2 groups. Group A showed more favorable outcome proportion (mRS 0-3, 6/15 patients vs. 5/23 patients, p=0.225) and lesser mortality cases proportion 1/15 patients vs. 4/23 patients, but these differences were not significantly observed (p=0.225 and 0.339). CONCLUSION: DC using n-shaped skin incision was a feasible and safe surgical technique. It may be an easier and faster method for the purpose of training neurosurgeons.

The purpose of treatment for metastatic spine tumor is to improve the quality of life. So, it is very important to carefully select the surgical candidates to prevent unnecessary surgery-related morbidity and mortality. For this purpose, the authors have surveyed 200 cases of spinal metastasis treated by radiotherapy alone or radiotherapy plus surgery to determine prognostic factors. In this study, we attempted to examine retrospectively the four factors, e.g.,primary tumor, pretreatment neurologic status, general condition and degree of cancer extension, affecting the prognosis of metastatic spine tumors. Each factor was ranked from 1 to 3 points according to the severity and the total score for each patient was obtained by adding the these points. As a result, it was found that the total score was highly correlated to the survival period. While the patients with a total score of 6 or lower survived 100 days or less, those of 10 or higher survived 300 days or more on average. Therefore, authors believe this scoring system would be helpful to the determine treatment modalities and the selection of the most suitable operative procedures.

PURPOSE: The purpose of this study is to assess the periopertive morbidity and mortality rates in relation to the principal variables in aged patients who undergo laparoscopic colorectal resection. METHODS: From March 2001 to March 2006, the prospective laparoscopic colorectal resection database was used to identify 233 patients. Among them, 132 were 70 years of age or older and they were classified as the aged group. 101 were younger than 70 years of age and they were classified as the younger group. RESULTS: Comorbidity was more common in the aged group than in the younger group (67.4% and 53.5%, respectively) (P=0.030). There were higher ASA scores in the aged group (I: 2.3% II: 68.2% III: 29.5%) than in the younger group (I: 27.7% II: 56.4% III: 15.8%) (P<0.0001). There was a higher postoperative complication rate for the aged group than for the younger group (25.0% and 8.9%, respectively) (P=0.002). Only one case of mortality (0.8%) was found in the aged group. The period of the postoperative hospital stay was longer for the aged group than that for the younger group (21.9+/-3/416.3 days and 16.3+/-3/48.1days, respectively) (P= 0.002). For the aged group, univariate analysis revealed that the operative procedure, disease, the T stage and the operation time were significant variables for the postoperative complications, and multivariate analysis identified the operation time as an independent variable faor the postoperative complications. CONCLUSION: More prudent care is needed to prevent postoperative complications for the aged patients who undergo laparoscopic colorectal resection, and particularly for those who can be expected to have a longer operation time.

INTRODUCTION: Nasopharyngeal angiofibroma is a rare histologically benign tumor which occurs almost exclusively in adolescent boys. The morbidity and mortality associated with this tumor are related to its prominent vascularity and its propensity for aggresive local growth. MATERIALS AND METHOD: From November 1990 through February 1996, 8 patients with a diagnosis of nasopharyngeal angiofibroma were managed at Asan Medical Center. For the devasculation of the tumor before the surgery, preoperative arterial embolization was performed on 6 patients. RESULTS: The main tumor supplying vessel was ipsilateral internal maxillary artery in all cases. According to Chandler classfication(Table 1), stage II was 4 cases and stage III was 4 cases. Operative procedures were midfacial degloving approach(4 cases), transpalatal approach(1 case), transantral approach(1 case), combined approach(1 case: Caldwell-Luc op & endoscopic op), medial maxillectomy(1 case). There were no treatment-related deaths and no major surgical complications.

PURPOSE: To propose a new, multivariable risk-scoring model for predicting 30-day mortality in individuals underwent repair of abdominal aortic aneurysms (AAA). METHODS: Four hundred eighty-five consecutive patients who underwent AAA repair from January 2000 to December 2010 were included in the study. Univariate and multivariate analyses were performed to evaluate the risk factors, and a risk-scoring model was developed. RESULTS: Multivariate analysis identified three independent preoperative risk factors associated with mortality, and a risk-scoring model was created by assigning an equal value to each factor. The independent predictors were location of the AAA, rupture of AAA, and preoperative pulmonary dysfunction. The multivariable regression model demonstrated moderate discrimination (c statistic, 0.811) and calibration (Hosmer-Lemeshow test, P = 0.793). The observed mortality rate did not differ significantly from that predicted by our risk-scoring model. CONCLUSION: Our risk-scoring model has excellent ability to predict 30-day mortality after AAA repair, and awaits validation in further studies.

PURPOSE: Although common femoral artery endarterectomy (CFAE) is regarded as the standard treatment modality for common femoral artery (CFA) disease, availability of advanced endovascular techniques has resulted in an increased number of CFA disease being treated. We evaluated clinical outcomes in a contemporary series of patients who were treated for CFA disease using endarterectomy alone or combined with endovascular treatment. MATERIALS AND METHODS: We retrospectively reviewed 46 patients from November 2001 through December 2007. The treated lesions were divided into 4 groups based on operative procedure: group I (n=11), CFAE alone; group II (n=15), CFAE and iliac artery (IA) endovascular treatment; group III (n=6), CFAE and superficial femoral artery (SFA) endovascular treatment; group IV (n=14), CFAE and IA and SFA endovascular treatment or bypass surgery. RESULTS: The degree of CFA steno-occlusion was not different among the groups. The 3-year primary patency rates of each group were 88.9±10.5%, 60.0±14.5%, 62.5±21.3%, and 83.9±10.4%, respectively. The 3-year primary assisted patency rates were 100%, 70.0±13.0%, 62.5±21.3%, and 89.3±10.4%, while 3-year secondary patency rates were 100%, 80.0±13.0%, 62.5±21.3%, and 92.3±7.4%, respectively. There was no procedure-related mortality. Significant improvement of ankle-brachial index was achieved in all groups. CONCLUSION: CFAE alone is the treatment of choice for excellent patency and clinical improvement in steno-occlusive lesions confined to the CFA. In multiple steno-occlusive diseases, this procedure could be combined with endovascular procedures to reduce the operative risk in conditions with high morbidity.

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 51patients (> or = 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 (65~69 and over 70years). RESULTS: In preoperative evaulation, 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.

BACKGROUND: The location of intimal tear can vary in type A acute aortic dissection. The aim of this study was to assess the operative result according to the intimal tear site. MATERIAL AND METHOD: From January, 1995 to May, 2003, 18 patients underwent surgery for acute type A aortic dissection. The patients were classified according to the intimal tear site. In Group I (n=11), the intimal tear site was located within the ascending aorta, in Group II (n=7), the intimal tear site was located in the aortic arch, descending aorta, or intramural hematoma only. All clinical data were analyzed retrospectively. RESULT: In Group I, the operative time, cardiopulmonary bypass time, aorta cross clamp time and circulatory arrest time were 381.5+/-81.0 min, 223.5+/-42.5 min, 146.4+/-34.8 min and 36.5+/-17.4 min, respectively; and in group II, 461.7+/-54.0 min, 252.5+/-45.3 min, 162.5+/-45.3 min and 47.0+/-14.4 min respectively. All of those were greater in group II. The overall hospital mortality rate was 27.8% (5/18) and was significantly higher in Group II (57.1%)(p=0.003) compared to that in Group I (9.1%). The causes of death were hemorrhage (n=1) in group I and hemorrhage (n=2), multiple organ failure (n=1), and rupture of abdominal aorta (n=1) in group II. CONCLUSION: Surgical treatment of acute type A aortic dissection with intimal tear in the ascending aorta results in an acceptable mortality rate, but in patients with intimal tear in the aortic arch or descending aorta, the operative mortality still remains high when only ascending aorta replacement was performed. In these circumstances, in order to improve surgical results, efforts to include the intimal tear site in the operative procedure will be needed.

PURPOSE: There has been controversy over an adequate operative method for peptic ulcer perforation, but currently there is general agreement in the surgical literature that perforated duodenal ulcers in patients who constitute excessive surgical risk should be managed by the simplest possible procedure and in the absence of surgical risk, definitive operations are advocated. However, an accurate description of the degree of severity of concurrent medical disease and surgical risk factor is not available and the question as to whether the postoperative mortality is influenced by the magnitude of the procedure or determined only by the patient's risk remains unanswered. METHODS: This retrospective study reviewed the case histories of all patients who underwent operations for perforated duodenal ulcer at Gil Medical Center from January 1993 through 1998 and evaluates the influences of prognostic factors, APACHE II, SAPS, age, duration of peritonitis, concurrent major medical disease and ulcer size, and operative procedures on postoperative mortality in high risk and low risk groups. RESULTS: Large APACHE II score (> or =15) and SPSS (> or =10), delayed operation, large ulcer (> or =2 cm), age (> or =60), and major medical illness that severely compromised cardiorespiratory, hepatic, renal, and immunologic function were associated significantly with mortality in patients with a perforated peptic ulcer. CONCLUSION: Age, duration of peritonitis, major medical disease, APACHE II score, and ulcer size should be pre-sumed to be important prognostic factors. Although further study is necessary in a larger number of patients, it appears that operative procedures have no influence on postoperative mortality.

PURPOSE: Hepatic resection is generally considered as the most satisfactory treatment for patients having intrahepatic stones. Yet for cases of right-sided intrahepatic stones, role of hepatic resection is still ambiguous because of the higher operative risks that are entailed when performing surgery at that location. This report presents the results of hepatic resection for the treatment of right-sided intrahepatic stones. METHODS: Seventy-one patients with right-sided intrahepatic stones were operated on during a period of 14 years. The operative procedures executed in the patients were 40 hepatic resections and 31 biliary lithotomies. We analyzed the operative findings and the results of treatment were then compared between the two treatment groups. RESULTS: The intrahepatic bile duct changes associated with stones were cholangitis (n=16), biliary stricture (n=31), biliary dilatation (n=13), and liver atrophy (n=11). Biliary dilatation and liver atrophy were more frequently observed in patients with hepatic resection (p< 0.05). Operative complications occurred in 6.5% of patients after biliary lithotomy and in 25.0% of patients after hepatic resection. There was no operative mortality in both groups. Retained stones were found in 51.6% of patients after biliary lithotomy. There were no retained stones in patients undergoing hepatic resection. After biliary lithotomy, the rate of retained stones was higher for patients having associated bile duct strictures and dilatations (cholangitis; 18.2%, stricture; 64.7%, dilatation; 100%, p< 0.05). Recurrent stones were found to have developed in 10 patients (14.2%), yet the rates for the recurrent stones were not different in both groups. CONCLUSION: Hepatic resection is an effective and safe treatment for right-sided intrahepatic stones. For intrahepatic stones associated with definite bile duct strictures, hepatic resection is the most suitable procedure for the complete removal of stones.
