Two cases of primary torsion of the greater omentum were described. The first patient was a 5-year-old boy who was admitted to the hospital because of severe abdominal pain for 1 day. The The clinical features were similar to perforated acute appendicitis. Laparotomy revealed a normal appendix and the greater omentum twisted around its pedicle. The second patient was a 7-year-old girl admitted to the hospital because of abdominal pain in right lower quadrant for 2 days. The clinical features? were that of acute appendicitis. Laparotomy revealed a normal appendix and primary torsion of greater omentum around its pedicle. In both cases, resection of twisted omentum and incidental appendectomy were done. The microscopic findings in two cases consisted of congestion and vascular hemorrhage. Both patients recovered uneventfully. Torsion of the greater omentum, therefore, may be added to the entities to consider in the differential diagnosis of acute appendicitis.

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.

One case of primary omental torsion in a 10 year-old, 43 kg boy is presented. He presented with a history of acute, continuous pain in the upper abdomen, aggravated by changes of position. Physical examination of his abdomen showed board-like rigidity. tenderness and rebound tenderness over the entire abdomen. The preoperative diagnosis was perforated peptic ulcer. Exploratory laparatomy revealed torsion of the greater omentum. The torsed omentum was excised and the outcome was good. Omental torsion is a rare surgical condition and is difficult to diagnose prior to operation. Therefore, in case of negative exploration for acute abdomen, the omentum should be included among the organs examined. In addition, careful search for an inflammatory focus should be made, because secondary omental torsion with intraabdominal sepsis is much more common than primary torsion.

Abdominal cystic lymphangiomas arising from the mesentery, omentum and retroperitoneum are rare and occasionally confused with other cause of acute abdomen. Sixteen children who underwent surgery for abdominal cystic lymphangioma between 1984 and 2005 at the Division of Pediatric Surgery, Keimyung University Dongsan Medical Center were evaluated retrospectively. There were 9 boys and 7 girls. Age ranged from 12 days to 13 years (mean age: 4.7years). The cysts were located in the omentum (4 cases),mesentery (9 cases: jejunum: 3, colon: 6). retroperitoneum (2 cases) and pelvic cavity (one case). The cyst content was hemorrhagic (8 cases), serous (5 cases), and inflammatory (2 cases), and chyle (one). Prenatal diagnosis was made in 3. The clinical features were variable, but abdominal pain, mass, and abdominal distention in order. There were 3 emergency operations in patients with complicated cyst, who were suspected of having panperitonitis and volvulus preoperatively. Complete excision was accomplished in all cases. There was one mortalityin a newborn with E.coli sepsis. Intestinal obstruction developed in 2 cases in long-term follow-up. No recurrence was observed. Although intraabdominal lymphangioma arising from mesentery, omentum and retroperitoneum are rare, it should be considered as a possible cause of acute abdomen.

A 48 year old woman was diagnosed with a huge cystic mass in her abdominal cavity. She complained of significant abdominal discomfort due to the mass. The abdominal computed tomography revealed a giant multi-lobulated mass, measuring $26{\times}12$ cm in size, adjacent to the lesser curvature of the stomach. In the operation field, the mass was found to originate from the lesser omentum, including the right and left gastric vessels and the vagus nerves, and to invade the lesser curvature of the stomach. For curative resection, distal subtotal gastrectomy with mass excision followed by gastroduodenostomy were performed. This mass was pathologically diagnosed to be a mesenteric cystic lymphangioma; in fact, the largest ever reported. The patient had no complications during the postoperative period and was discharged from the hospital on the seventh day after surgery.

Background Although the utility of flaps for the treatment of sternal wound infections following median sternotomy has been reported for 30 years, there have been few reports on the risk factors for complications after reconstruction. The objective of this investigation was to identify factors related to complications after the reconstruction of sternal wound infections. Methods A retrospective analysis of 74 patients with reconstructive surgery after sternal wound infection over a 5-year period was performed. Clinical data including age, sex, body mass index (BMI), comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected. Results The patients' BMI ranged from 15.2 to $33.6kg/m^2$ (mean, $23.1{\pm}3.74kg/m^2$). Wound closure complications after reconstructive surgery were observed in 36.5% of the cases. The mortality rate was 2.7%. Diabetes mellitus significantly affected the rate of wound closure complications (P=0.041). A significant difference in the number of complications was seen between Staphylococcus aureus (S. aureus) and coagulase-negative Staphylococci (P=0.011). There was a correlation between harvesting of the internal thoracic artery and postoperative complications (P=0.048). The complication rates of the pectoralis major flap, rectus abdominis flap, omentum flap, a combination of pectoralis major flap and rectus abdominis flap, and direct closure were 23.3%, 33.3%, 100%, 37.5%, and 35.7%, respectively. Conclusions Diabetes mellitus, S. aureus, harvesting of the internal thoracic artery, and omentum flap were significant factors for complications after reconstruction. The omentum flap volume may be related to the complications associated with the omentum flap transfer in the present study.

The treatment of acute and chronic empyema with bronchopleural fistula is remained as serious postoperative complication in thoracic surgery. Although several operative procedures for the treatment of postpneumonectomy empyema have been reported, the method of treating empyema, and in particular empyema associated with fistula, remains controversial. Recently some successful results have been reported by use of the omentum in the patients with thoracic empyema resulting from bronchial fistula. We have performed one-stage operations using the omentum and chest wall muscles in 2 patients, one was acute, and the other was chronic case. Their postoperative courses were uneventful

Two cases of traumatic diaphragmatic hernia are reported, who were operated on in this department during the last 12 months` period. The first case, a 34 year old male, fell from 6 meters` height while he was working on electric pole. He sustained rib fractures, left 8th, 9th and 10th rib, left diaphragmatic rupture and ileal perforation. In the pleural cavity, there were stomach, omentum, left lobe of liver, transverse colon and ileum, which were reduced into the peritoneal cavity, and the diaphragmatic aperture was closed through anterolateral thoracotomy. After closure of the thoracic incision, median abdominal incision was made and closed the ileal perforation by primary suture. The second case was a 19 year old tyre repairman, who felt abrupt severe abdominal pain during lifting a heavy lyre. A barium study revealed a marked displacement of the stomach into the left pleural cavity. Immediately, thoracotomy was performed and closed the ruptured diaphragm after reduction of the herniated stomach, omentum, transverse colon, spleen and small intestine. The size of the diaphragmatic aperture were measured 17cm. in first case and 12cm. in the other respectively. Both cases discharged after uneventful recovery.

A ten-year-old dog was presented with pancreatitis and increased hepatic enzymes. On necropsy a large firm mass was observed in the liver extending to the gall bladder. Smaller masses with similar texture were found in multiple organs including lung, stomach, pancreas, lymph nodes, omentum, and mesentery. Neoplastic cells were spindle shaped with prominent osteoid production and occasional trabeculae of woven bone. Tumor cell emboli were observed in the blood vessels and lymphatics of the omentum and stomach. Hepatic osteosarcoma with systemic metastasis is very rare and may serve to broaden the diagnostic spectrum of hepatic and pancreatic diseases in dogs.
