Analyses were done on one hudred and twenty caaes of bleeding gastric ulcers diagnosed by emergency endoscopy for the past five years. The reaults are as the following: Much more cases were found in male than female and the most prevalent age group was 6th decade. The body of stomach along the lesser curvature was the most common bleeding site. No age related difference was noted in bleeding sites. Most common type of ulcer was in the round and shallow form. Five of six cases with exposed vessels showed atrophic changes in surrounding mucosa. Among the probable precipitating factors, analgesica, alcohols and certicosteroids were found in such order,

Background:
The aim of this study was to evaluate the short-term and long-term results of surgical treatment for native valve endocarditis (NVE) and to investigate the risk factors associated with mortality.
Methods:
Data including patients’ characteristics, operative findings, postoperative results, and survival indices were retrospectively obtained from Hallym University Sacred Heart Hospital.
Results:
A total of 29 patients underwent surgery for NVE (affecting the mitral valve in 20 patients and the aortic valve in 9) between 2003 and 2017. During the follow-up period (median, 46.9 months; interquartile range, 19.1–107.0 months), the 5-year survival rate was 77.2%. In logistic regression analysis, body mass index (p=0.031; odds ratio [OR], 0.574; 95% confidence interval [CI], 0.346–0.951), end-stage renal disease (ESRD) (p=0.026; OR, 24.0; 95% CI, 1.459–394.8), and urgent surgery (p=0.010; OR, 34.5; 95% CI, 2.353–505.7) were significantly associated with in-hospital mortality. Based on Cox proportional hazard regression analysis, the statistically significant predictors of long-term outcomes were hypertension, ESRD, and urgent surgery.
Conclusion
Surgical treatment for NVE is associated with considerable mortality. The in-hospital mortality and 5-year survival rates of this study were 13.8% and 77.2%, respectively. Underlying conditions, including hypertension and ESRD, and urgent surgery were independent risk factors for unfavorable outcomes.

Vitamin C acts as a antioxidants and as free radical scavengers in biological systems. The objective of this study was to examine whether the administration of vitamin C could improve the skin flap survival. Sprague-Dawley rats (n = 40) were divided into 4 groups (n = 10); normal saline, vitamin C 200 mg/day, vitamin C 500 mg/day, vitamin C 1000 mg/day were injected subcutaneously to each group (n = 10). A classic caudally based random flap (2 X 7 cm) was elevated on the dorsum of rats and then sutured to its normal position. On the 3rd, 7th, 14th days postoperatively each animal was evaluated for percentage area of flap survival by paper template technique, thereafter rats were sacrificed and we obtained tissue from the distal ends of the flap. Following is our results. 1) The experimental group treated with vitamin C revealed an increased rate of random pattern skin flap survival compared with the control group (p < 0.005). 2) There was correlation of vitamin C dosage with flap survival rate (Spearman's correlation coefficient = 0.971). 3) The biopsy of the control group showed extensive atrophy and necrosis. However, New capillary proliferation and collagen deposition were noted in the vitamin C 200 mg and 500mg treated group. In the vitamin 1000 mg group, microscopic findings were very alike compared with normal rat skin texture. Finally, we concluded that the Vitamin C supplement increases survival rate of random pattern flap in rat skin flap model, and flap survival is correlated with vitamin C dosage.

A 55-year-old female presented to Pusan National University Yangsan Hospital with left neck and shoulder pain. An anterior mediastinal mass was detected on chest CT and there were no other specific lesions in the lung or pleural cavity. An infected pericardial cysts was suspected and excision was performed through a left-sided VATS approach. The patient was discharged on the second post-operative day with left diaphragm palsy and praziquantel was prescribed after paragonimaisis was confirmed on pathology. The patient has not shown any particular problems at my outpatient clinic.

A 12-year-old female presented with the abnormal findings on the chest PA. The chest CT revealed a retrosternal defect of the diaphragm and a fatty opacity in the pleural cavity, resulting in a diagnosis of Morgagni hernia. It was decided to undergo a laparoscopic surgery. The retrosternal defect of the diaphragm measuring 3.5 cm in diameter was found, through which a portion of the greater omentum and the fatty tissue connected with the falciform ligament were herniated into the pleural cavity. The greater omentum was pushed back into the peritoneal cavity and the fatty tissue connected with falciform ligament was excised. The mediastinal pleura was plicated and the defect of the diaphragm was repaired primarily. Immediately after the operation, the patient developed a right pneumothorax for which a chest tube was inserted. She was discharged at the post-operative third day without any further complications.

The patient was an eight-year-old female. She was diagnosed as dilated cardiomyopathy. She was supported with bi-ventricular assist because of heart failure for 15 days. After 7 days, she was suffered from prerenal type ARF and support with continuous veno-veno hemodyalisis (CVVHD). And then heart transplantation was performed, heart donor's blood type was A. Immune suppressants were used after due consideration for renal toxicity. ARF was resolved on post operative 14th day. She was discharged on post operative 52nd day without any specific post operative complication. She has been followed up without any immune rejection reaction upto 14 months.

BACKGROUND: The purpose of this paper is to present a guideline for beginning video-assisted thoracic surgery (VATS) lobectomy to junior surgeons, and to review the first year experience of a new surgeon performing VATS lobectomies who had not performed a VATS lobectomy unassisted during his training period. MATERIALS AND METHODS: A young surgeon opened a division of general thoracic surgery at a medical institution. The surgeon had performed about 100 lobectomies via conventional thoracotomy during his training period, but had never performed a VATS lobectomy unassisted while under the supervision of an expert. After opening the division of general thoracic surgery, the surgeon performed a total of 38 pulmonary lobectomies for various pulmonary diseases from March 2009 to February 2010. All data were collected retrospectively. RESULTS: There were 14 lobectomies via thoracotomy, 14 VATS lobectomies, and 10 cases of attempted VATS lobectomies that were converted to open thoracotomies. The number of VATS lobectomies increased from the second quarter (n=0) to the third quarter (n=5). The lobectomies that were converted from VATS into thoracotomies decreased from the second quarter (n=5) to the third quarter (n=1) (p=0.002). CONCLUSION: It can take 6 months for young surgeons without experience in VATS lobectomy in their training period to be able to reliably perform a VATS lobectomy.

PURPOSE: The purpose of this study was to determine the extent of safety of medial dissection of the thyroid gland along the trachea. Medial to lateral dissection of the thyroid gland along the trachea after early division of the isthmus has been known to be a useful technique in thyroid surgery, especially for difficult cases, but the risk of injury of the recurrent laryngeal nerve (RLN) has constrained thyroid surgeons from utilizing this technique to its full extent. METHODS: Distances of the laryngeal entry point (LEP) of 134 RLNs of 71 patients from the midline of the trachea, and some other anatomical distances, were measured intraoperatively. The relationships of the intraoperatively measured data with circumferences of the cartilaginous portion of the trachea (CCT) around LEP measured preoperatively by CT scan were evaluated. RESULTS: LEP was always located within 2 mm vertically from the horizontally extended line of the inferior border of the cricoid cartilage and was the closest point from the midline in the whole course of the RLN. The distance between LEP and the midline was very closely correlated with CCT measured on preoperative CT scan, and it can be accurately calculated with a regression equation; Distance between LEP and the midline = (0.42 × CCT) + (1.2 × sex) + 3.2 (mm) (sex: female=0, male=1; R2 = 0.85). CONCLUSION: Early division of the isthmus and dissecting the thyroid off the trachea to the calculated extent is a safe and effective procedure.
