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.

장간막과 대망에서 원발성으로 생기는 종양은 비교적 흔하지 않지만, 종양과 비슷한 다양한 질환과의 감별이 필요한 경우가 많다. 또한, 다양한 복부 질환의 확산 경로이기 때문에 정확한 감별진단을 위해서는 장간막과 대망에 대한 해부학과 질병 종류 및 양상에 관하여 자세히 알아야 할 필요가 있다. 또한, 장간막과 대망의 숨어있는 병변들을 잘 찾아내어 적시에 정확한 치료를 하는 것이 중요하므로 복부 CT 판독 시 병변이 잘 생기는 부위를 잘 관찰하여야 한다.

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.

혈관종증(hemangiomatosis)은 하나 혹은 여러 개의 장기에서 다발성으로 발생하는 혈관종(hemangioma)이다. 혈관종증은 주로 간에서 나타나며 대망(greater omentum)과 장간막(mesentery)에 발생하는 경우는 매우 드문 경우로 보고된 예가 적다. 저자들은 특별한 증상이 없는 62세 남자 환자에서 간을 포함한 대망과 장간막에 우연히 발견된 혈관종증의 컴퓨터 단층촬영, 자기공명영상 소견을 병리 소견과 함께 보고자 한다.

대망의 서혜부 탈장에 의한 이차성 대망 염전은 급성 복통의 원인으로써 드물게 보고된 바 있다. 그러나 만성 복통의 원인으로써 이차성 대망 염전이 섬유성 벽을 가진 거대하고 단단한 종괴로 발견되는 것은 이전까지 보고되지 않았기에 이를 보고하고자 한다. 74세 남자 환자가 한 달간 지속된 만성적인 하복부 복통과 우하복부에 만져지는 종괴를 주소로 내원하였다. 시행한 서혜부 초음파상에서 양쪽 서혜부 탈장이 관찰되었다. 컴퓨터단층촬영상에서 오른쪽 서혜관으로 대망의 일부가 빠져나갔고 그 축을 중심으로 대망 염전이 있었다. 염전 줄기의 원위부 대망은 우하복부와 골반강에 걸쳐 단단한 섬유성 벽을 가진 약 30 cm 정도의 거대한 종괴를 형성하였다. 환자는 복강경하 장막 절제술 및 양쪽 탈장 수술을 시행 받은 뒤 퇴원하였다.

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.
