Extragastrointestinal stromal tumor (EGIST) has been reported to occur only rarely, and the cases of this disease appearing as cystic masses are also known to be very infrequent. Along with a review of the related articles, we report here on a case of EGIST arising from the omentum that was seen as a multiloculated large cystic mass with multiple thick septa and a solid component.
Omentum*

Omentum has the characteristic that it readily develops vascular anastomosis with adjacent tissues. It is suitable for eliminating a dead space regardless of the size, shape or site in the treatment of chronic osteomyelitis by use of technique of microvascular anastomoses. We report a case of chronic osteomyelitis treated by transplantation of autogenous omentum with microvascular anastomsis.

The omentum is unique in that it is the body tissue developed for the resolution of local inflammatory processes because of combination of its blood supply and abundant lymphatic drainage. Thus, the use of omentum is well established for the more complex reconstruction of the urinary tract. We managed 3 cases of multiple severe renal injury using omentum and results were favorable.

Xanthogranulomatous cystitis is a rare benign chronic inflammatory disease of unknown etiology. Herein, an extensive case presenting as a mass around the dome of bladder, with infiltration of perivesical fat and a part of omentum, is reported.

Herein, we report on a case of primary torsion of the greater omentum with segmental infarction, which should provide useful information for the preoperative diagnosis of future such cases. Primary torsion of the greater omentum with omental infarction is a rare condition. There are only a few radiological reports of secondary torsion of the greater omentum caused by the hernial sac. During surgical exploration, infarction of the greater omentum was identified, due to the observation of omental torsion without any underlying cause. We describe a patient with characteristic computed tomography (CT) findings of primary omental torsion with segmental infarction, which correlated with the operative and pathologic results.

Extensive and complicated defects on the body call for an omnipotent tool for a perfect reconstruction. Flaps derived from the omentum has many advantages over the conventional flaps. From 1999 to 2004, Omental flaps were applied for various soft tissue reconstructions. Among total 20 total 7 cases were for immediate reconstruction, 2 cases for chronic infection, 3 cases for simultaneous reconstruction of two defects, 4 cases for functional joint reconstruction and 4 cases were for flow- through revascularization. Among these cases, 3 cases were operated with minimal incision harvest technique. There were no complete flap failures, partial necrosis of the distal parts were noted on three cases. The omental flap is indicated on a large contaminated defect reconstruction due to its large size, well-vascularized, and malleable properties. The omental flap provides several additional advantages over other flaps, which are; the availability of the one staged simultaneous reconstruction of two defects with one flap, providing gliding function for the joint motion, and a flow-through characteristics with long vascular pedicle. But there are some serious shortcomings, including a long abdominal scar and intraabdominal problems. However, these are rare and can be minimized with our minimal incision technique. Due to its unique characteristics. the omentum is one of the ideal tissues for the reconstruction of the complicated soft tissue defects due to its unique characteristics.

Liver lacerations are the most common intra-abdominal injury that leads to death, and control of hemorrhage remains the primary problem in lowering mortality. The perihehatic packing is a important technique for selected patients with major liver injuries. A major problem associated with perihepatic packing has been the adherence of the laparotomy pads to the raw surface or the omentum, which leads to recurrent bleeding related to clot disruption and avulsion of the hepatic parenchyma when the packs are removed. We had the opportunity to prevent renewed bleeding using Steri-Drapes in patients with hepatic laceration. Reported here are the effectiveness of Steri-Drepes in perihepatic gauge packing.

Primary torsion of the greater omentum is a rare cause of an acute abdomen in children, which often mimic other acute abdominal conditions. Resection of the infarcted segment is the treatment of choice. Here, a case of torsion of the greater omentum, diagnosed with preoperative computed tomography and subsequently managed by laparoscopic surgery, is reported. The patient was discharged three day after surgery without any complication. Omental torsion can be accurately diagnosed and safely treated with a laparoscopy.

Primary peritoneal cancer is a rare tumor, which may be mesothelial or mullerian in nature. It can develop from unifocal or multifocal origin and the clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but the main features of primary peritoneal cancer are widely disseminated malignancy along the peritoneal surfaces, the omentum, and abdominal viecera, with minimal or no ovarian involvement. Recently investigators have analyzed the morphology of these tumors and have used histochemical, eletron microscopic and immunohistologic techniques in an attempt to identify, characterize, and categorize. We have experienced a case of a primary peritoneal cancer which developed in the patient who had probably a previous total hysterectomy and both salpingooophorectomy.
