A nine-year-old neutered male cat was presented with chronic cough and vomiting. Thoracic radiography showed regions of fatty opacity in the right caudoventral region. On positive contrast celiography, contrast agent did not move into thoracic cavity. Computed tomography revealed 7-mm diameter of defect at the right diaphragmatic crus and a 2-mm diameter defect at the left ventral diaphragmatic crus. Through the right diaphragmatic defect omental herniation was confirmed by the presence of contrast enhanced omental vessel running across the diaphragm. On exploratory thoracotomy, the omentum protruded into the thorax through the right diaphragmatic defect, and it contained a yellowish lipomatous mass. The protruded omentum containing a mass in the thorax was removed, and the right diaphragmatic defect was closed. Histopathologic examination revealed that the protruded omentum showed normal omental structure and the adipose mass showed lipoma surrounded by fibrous tissue. In conclusion, a thorough examination is necessary to confirm the origin of the mass located near the diaphragm.

Acute mediastinitis and subsequent graft infection following aorta surgery poses a difficult problem, as infected synthetic material must be completely removed for resolution of infection. Here we report a case of successful management of acute mediastinitis following hemiarch replacement for acute aortic dissection with omental flap transfer leaving infected graft in situ.

This study was designed to determine the effects of the insulin-like growth factor (IGF-1) and estradiol $17-{\beta}$ on the in vitro proliferation of stromal vascular cell from Hanwoo omental, subcutaneous, intermuscular and intramuscular adipose tissues. Cells were cultured in M199+20% newborn calf serum and the proliferation of cells was measured by direct microscopic cell counting and change of genomic DNA amount. Cell numbers increased slightly over the first 72 hour of culture and then increased greatly, regardless of adipose tissue depots. In IGF-1 treatment, the number of omental preadipocytes maintained highest level from the beginning to the 20th day of culture. However, in estradiol-$17{\beta}$ treatment, those tended to be lower than the control from the beginning of culture and significantly lower at the 24th day. When IGF-1 was added to subcutaneous preadipocytes, the numbers of cells were higher from 11th day than those from other treatments, although there was no statistical significance. For intermuscular preadipocytes treated with IGF-1, its numbers were significantly (p<0.05) higher at 11th day, and in the other days it showed a similar tendency to those of the subcutaneous tissue. In this experiment, preadipocytes were taken from 24 month old fully matured steers and the highest proliferation rate was shown in intramuscular tissue followed by those of subcutaneous preadipocytes. Addition of $5{\mu}M$ estradiol-$17{\beta}$ to the growth medium failed to promote the replication of Hanwoo preadipocytes, as indicated by direct cell counts and total genomic DNA content. As the culture period proceeded, the amounts of DNA were increased, but the patterns of increment were not consistent with the results of cell numbers.

Mesenteric and omental cysts are rare intra-abdominal lesions in childhood, and may present various clinical features such as an asymptomatic mass or an acute abdomen. Therefore, these entities are frequently misdiagnosed preoperatively or are found only incidentally at operation for other conditions. We analyzed our experiences of 19 cases in a 19 year period from 1981 to 1999, at College of Medicine, Catholic University of Korea. There were 12 boys and 7 girls with a mean age of 4.8 years (range, 3 days to 15 years). Common presenting symptoms were abdominal pain (47%), abdominal distension (31%), abdominal mass (24%), vomiting (15%) and fever (10%). Ultrasonography was the most preferred method of diagnosis. Other diagnostic modalities include CT, MRI, and abdominal ascites tapping in selected patients. Location of the mesenteric cysts was small bowel mesentery in nine, the right mesocolon and retroperitoneum in one, the left mesocolon in one, and the jejunum, sigmoid-colon mesentery in one. Most of the patients underwent cyst excision, but six patients required concomitant bowel resection for complete removal of the lesions, and two patients underwent unroofing and simple aspiration respectively. There was one mortality case due to sepsis.

We report a successful right,sleeve pneumonectomy using femoro-femoral bypass on a 26-year-old woman with severe carinal and lower tracheal stenosis of tuberculous origin. Omental graft on the anastomotic site was added, There was no specific postoperative complication and postoperative bleeding was minimal.

Leiomyosarcoma (LMS) of the small intestine is a rare tumor, accounting for about 1% of all malignant mesenchymal lesions in the gastrointestinal tract. Since small bowel tumors are initially asymptomatic and nonspecific, delayed diagnosis and treatment are common. We found that a 44-year-old male patient who came in for lower abdominal pain had partial obstruction in the small bowel. Multiple ascites and ileal tumors involving peritoneal seeding were observed from his abdominal computed tomography. He was diagnosed as epithelioid LMS involving peritoneal transition after surgical resection, and the outpatient department has planned for a conservative therapy with observation. To the best of our knowledge, ileal epithelioid LMS accompanying a huge omental mass, with a size of 18 cm in dimension, and peritoneal seeding has not yet been reported in Korea. We report this rare case with literature review.

A trocar site hernia is a rare complication. We report a patient who had an abdominal wall mass at a previous trocar site after laparoscopic distal gastrectomy. It was diagnosed as omental herniation and fat necrosis. We conclude that patients with trocar site masses exhibiting fat density on a computed tomography scan could be followed up without surgery, and that fascial defects located at 10-mm or larger trocar sites should be closed whenever possible to prevent hernia formation.
