The present study was conducted to compare the effects of xenogenic bovine fetal demineralized bone matrix (DBM), commercial DBM, omentum, omentum-calf fetal DBM, cortical autograft and xenogenic cartilage powder on the healing of tibial defects in a dog model to determine the best material for bone healing. Seven male adult mongrel dogs, weighing 26.2 ± 2.5 kg, were used in this study. Seven h...

OBJECTIVE The purpose of this study was to describe the probable mechanism of the volume increase of laparoscopically harvested omentum flaps used to treat breast deformities. METHODS A histological analysis of omentum samples was performed to study the volume increase of laparoscopically harvested omentum flaps. Samples were harvested immediately after the transposition of the omentum from t...

PURPOSE To describe MR findings in patients who have undergone omental transposition (omental myelosynangiosis) for spinal cord revascularization. METHODS Spin-echo MR images, without and with intravenous gadolinium, were obtained before and after surgery in three patients using a quadrature spine coil. Three-dimensional time-of-flight spinal MR angiography was also performed. RESULTS On ro...

CASE HISTORY A 10-year-old boy was admitted with pain in the right iliac fossa for two days, which was made worse by movement and coughing. He was not nauseated and he did not vomit. He had not eaten for two days. Pulse rate was 70 oer min and temperature 37.4°C. There was marked tenderness with rebound in the right iliac fossa. On rectal examination he was very tender on the right side. White ...

We report a case of solitary fibrous tumor (SFT) of greater omentum in a young woman. SFT arising from the greater omentum can mimic a gynecologic neoplasm. SFTs are generally benign but some of them are malignant and have uncertain prognosis. An adequate follow-up is essential in these patients.

BACKGROUND Rapid revascularization of islet cell implants is important for engraftment and subsequent survival and function. Development of an adequate vascular network is expected to allow adaptive growth of the β-cell mass. The present study compares omentum and kidney capsule as sites for growth and differentiation of immature β-cell grafts. METHODS Perinatal porcine islet cell grafts were...

BACKGROUND Mechanical catheter dysfunction caused by omentum entrapment remains a major complication of peritoneal dialysis (PD) therapy. The purpose of this study was to determine the outcomes of omentum folding at the time of primary open catheter insertion. METHODS From March 2008 to December 2012, a total of 67 PD subjects were enrolled in the study and randomly assigned to receive either...

BACKGROUND A complete omentectomy is recommended as part of radical (sub)total gastrectomy for gastric cancer, but there is little evidence to suggest any survival benefit. The aim of this study was to evaluate the incidence of, and risk factors for, metastases in the greater omentum in patients undergoing gastrectomy for gastric cancer. METHODS This was a multicentre prospective cohort study...

omental and mesenteric cysts are both rare pathologies in children. children who have omental cysts usually display symptoms of abdominal distension, with or without a palpable mass. the mass can simulate ascites on clinical observation, or tuberculosis on radiological images. the optimal treatment for this condition is complete resection. the presenting symptoms of abdominal distension and the...
