Pedicled omentoplasty is effective in thoracic surgery, but it is associated with several postoperative complications. A case of diaphragmatic hernia as a complication of pedicled omentoplasty in a 65-year-old male is reported. Because aortoesophageal fistula occurred three months after the patch aortoplasty for mycotic aneurysm of descending thoracic aorta, he underwent ascending thoracic aorta to abdominal aorta bypass surgery with resection of thoracic aortic aneurysm and esophagorrhaphy with wrapping of the esophageal suture line and the stumps of aorta with pedicled omental flap. Three years after the operation, herniation of the stomach developed. The pedicled omental flap was ligated and divided, and the diaphragm defect was repaired.

Omental torsion secondary to inguinal hernia has rarely been reported as a cause of acute abdominal pain. However, in our case, omental infarction due to prolonged inguinal hernia-associated omental torsion led to the formation of a large omental mass with marginal fibrosis, and the patient presented with chronic abdominal pain. A 74-year-old man presented with complaints of lower abdominal pain for 1 month; subsequently, bilateral inguinal hernias were identified through inguinal ultrasonography. CT scans revealed that the greater omentum was trapped within the right inguinal canal, leading to omental torsion. The greater omentum, distal to the pedicle, appeared as a 30 cm-sized oblong fibrofatty mass in the right lower abdomen and pelvic cavity. Laparoscopic omentectomy with hernia repair was successfully performed.

Background: Using the neovascularizing properties of the omentum, we studied the viability and vascularity of the cryopreserved rat tracheal allografts with omental implantation. Material and Method: The cryopreserved tracheal allografts of eight-week old male Sprague Dawley rats were implanted into the omentum. The rats were divided into the four groups according to the duration of cryopreservation and of omental implantation. We examined the tracheal allografts histologically for viability of cartilages, inflammation and fibrosis of smooth muscle and connective tissue, and degree of vascularity. Result: The degree of inflammation in the smooth muscle and the connective tissue of the tracheal allografts was not statistically related to neither the duration of cryopreservation or of omental implantation. The tracheal cartilages of the tracheal allografts were found to be severely calcified in all cases. Significant difference in vascularity was found between the groups I and II (p < 0.05). And a sufficient vascularity in the intercartilaginous space was observed in the mid portion of the tracheal allografts as well as both ends. Conclusion: In conclusion, the omental implantation for 2 weeks could establish a sufficient vascularity in the intercartilaginous spaces for maintaining the viability of the tracheal allografts. This study might provide a possibility of the sequential tracheal allotransplantation after omental implantation.

Although primary tumors in the mesentery and omentum are relatively rare, it is often necessary to distinguish them from other non-tumorous diseases. Since the omentum and mesentery are major routes for the spread of various abdominal diseases, the anatomy, type, and pattern of the diseases affecting these organs should be known in detail for accurate differential diagnosis. In addition, it is important to detect and promptly treat hidden lesions in the mesentery and omentum. Therefore, careful observation of the area where the lesion occur should be emphasized when assessing mesentery and omentum in abdominal CT.

A 59 year-old male diagnosed as unstable angina underwent off-pump coronary artery bypass surgery using in situ left internal mammary and right gastroepiploic artery grafts. During harvesting the right gastroepiploic artery, there was no abnormal finding in intraabdominal organs including stomach and liver. He was discharged at the 3rd postoperative day without complication. In case of using in situ right gastroepiploic artery, we recommend gastrofberscopic study at regular follow-up, The patient underwent the gastrofiberscopic study at postoperative 3rd month and diagnosed as advanced gastric cancer on the posterior wall of gastric fundus. At 5th postoperative month, total gastrectomy without intraoperative injury of the right gastroepiploic artery was performed at the department of general surgery. He was discharged at the 9th postoperative day. Follow-up coronary angiography performed at the 1st postoperative year demonstrated patent grafts including right gastroepiploic artery.

The aim of this study was to evaluate the early and midterm results of off-pump total arterial revascularization using the skeletonized right gastroepiploic artery (RGEA) as a third arterial conduit. Material and Method: We prospectively analyzed 103 patients who underwent off-pump total arterial revascularization using bilateral internal thoracic arteries (ITAS) and RGEA. The RGEA was used as in situ graft in 88 patients, composite graft in 10 patients, and free graft in 5 patients. Postoperative coronary angiographies were performed before discharge in 100 patients, and at postoperative one year in 88 patients. Result: The RGEA showed a significantly higher free flow (130$\pm$95 ml/min) than that of right ITA(113$\pm$57 ml/min) or left ITA (107$\pm$55 ml/min), which was measured before anastomosis (p < 0.05). The total number of distal anastomoses was 3.8$\pm$0.7. The number of distal anastomoses per bilateral ITAs was 2.8$\pm$0.7 and the number of distal anastomosis per RGEA was 1.0. There were two morialities including one operative mortality. The late mortality was not related to cardiac events. Early postoperative morbidities were atrial fibrillation in 15 patients, bleeding reoperation in 4 patients, mediastinitis in 1 patients, perioperative myocardial infarction in 2 patient, and transient ARF in 3 patients. Postoperative coronary angiographies showed the early patency rate of 98.6％ (272/276) for ITAs and 97.0％ (97/100) for RGEA, respectively (p=ns), and the one-year patency rate of 95.9％ (234/244) for ITAs and 88.6％ (78/88) for RGEA, respectively (p=0.07). Flow competition between the RGEA and NCA (native coronary artery) was seen in 5 of the 100 patients (5.0％) immediate postoperatively and 7 of the 88 patients (8.0％) 1 year after surgery. Since July, 2000, we measured transit time flow intraoperatively and could reduce flow competition significantly Conclusion: The skeletonized RGEA demonstrated excellent early and midterm patency rates and could be used as a third arterial graft following the bilateral ITAs.

Background: To maximize the histological advantage and minimize the physiological disadvantage, we have been using the skeletonized gastroepiploic artey (GEA) as a free graft for total arterial revascularization. The aims of the current study was to assess the efficacy of the skeletonized GEA as a composite or extended graft for total arterial revascularization. Material and Method: Between January 2000 and Feburary 2005, 133 patients (43 female, mean age=61.8 yrs) undergoing coronary artery bypass grafting (CABG) with a skeletonized GEA as free graft (22 extended, 107 composite and 4 others) were enrolled in this study. Coronary angiograms were performed in the immediate (median 44 days, n=86), early (median 366 days, n=56) and midterm (median 984 days, n=29) postoperative periods. Result: There were 3 ($2.2\%$) early and 4 ($3.3\%$) late cardiac-related deaths. The mean number of distal anastomoses per patient was 3.34 for total graft and 1.92 for GEA graft. The immediate, early, and midterm GEA patency were 157/159 ($98.7\%$), 106/142 ($94.6\%$), and 53/56 ($94.6\%$), respectively. During follow-up, four patients required percutaneous intracoronary intervention because of GEA and target coronary artery stenosis or competitive flow. Conclusion: These data demonstrate satisfactory clinical and angiographic results in the skeletonized GEA as free graft for total arterial revascularizatioh. Although we need a careful longer follow-up, the skeletonized GEA as a free graft will be a valuable option 'to be' for CABG.

장기간의 간기능 부전 증상을 보인 2살짜리 포인터종 개가 전남대학교 동물병원에 내원하였다. 방사선 소견상 조영제(바륨)와 가스가 찬 소장이 심낭에서 관찰되었다. 허니아로 인한 불량한 예후 때문에 심한 간기능 부전이었지만 외과적 수술을 시행하였다. 소장, 대망, 담낭을 포함한 간이 복막-심막 횡격막 허니아에 의해 심낭에 삽입되어 있었다. 소장은 심낭에서 쉽게 복구되었지만 대망과 간은 심낭과의 심한 유착으로 복구되지 못하였다. (중략)
