BACKGROUND Transplantation of cardiomyocytes that are derived from human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs) shows promise in generating new functional myocardium in situ, whereas the survival and functionality of the transplanted cells are critical in considering this therapeutic impact. Cell-sheet method has been used to transplant many functional cells; however, p...

Hemangiopericytoma (HP) is a vascular tumor that mostly develops in soft tissues. The greater omentum is a very rare site for its occurrence. We present herein the clinical evaluation and outcome of a very rare case of HP that caused acute abdomen. We evaluated a case of acute abdomen due to rupture of a HP of the greater omentum. The clinical and laboratory findings and treatment modality are ...

infarction is a rare condition. Infarction of the omentum causes localized acute abdominal pain and can therefore mimic other surgical emergencies. There is little information on this condition to be found in the radiological literature, because it is not usually diagnosed until surgical intervention, being previously diagnosed as acute appendicitis or acute cholecystitis (1, 2). There are only...

Primary tumors of the omentum are uncommon, and leiomyomas arising in the omentum are exceedingly rare. We report on a patient who presented with a large abdominal cyst presumed to be an omental cyst. At laparoscopy, after aspiration, the cyst was found to be attached to a solid mass arising from the greater omentum. The entire tumor was successfully excised laparoscopically. Histopathology an...

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...

BACKGROUND Use of alloplastic materials such as Gore-Tex and locoregional flaps for reconstruction of large abdominal wall defects has been well described. The purpose of this article is to present a novel technique of using the omentum as an interpositional flap to protect the Gore-Tex repair of the abdominal wall. METHODS Four patients with large abdominal wall defects underwent reconstruct...

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 computed tomography (CT) findings for a rare case of follicular dendritic cell sarcoma of the greater omentum from a 47-year-old female patient. The tumor presented ash a palpable mass lesion in the umbilical region for the last two months. Multidetector CT scan of the abdomen showed a 14-cm soft-tissue mass with calcification and necrosis within the greater omentum. As a result, a fo...
