omental torsion is caused by the rotation of the greater omentum on its axis which may lead to tissue infarction and necrosis. it is a rare cause of acute abdomen. signs, symptoms and paraclinical data are not specific. the patients usually undergo laparotomy for acute abdomen of poorly defined origin. high index of suspicious is required for the diagnosis of this entity. the diagnosis is usual...

Ewing's sarcoma (ES) is the second most common malignant bone tumor in children and young adults. ES also occurs as a primary soft tissue neoplasm without involvement of bone. We report the second case of extraosseous (EO) ES emerging from the omentum and a review of the relevant literature. EO ES should be included in the differential diagnosis of soft tissue neoplasms in the abdomen.

The fetal mouse omentum has been shown to be a source of precursors that exclusively reconstitutes Lyl + B cells and the closely related Lylsister population, but not conventional B cells or T cells. We have extended these studies to compare B cell development in the human fetal omentum, liver, and spleen, and to demonstrate that the pro/pre-B cell compartment (CD24 +, sIgM-) is detected in the...

The fetal mouse omentum has been shown to be a source of precursors that exclusively reconstitutes Ly1+ B cells and the closely related Ly1- sister population, but not conventional B cells or T cells. We have extended these studies to compare B cell development in the human fetal omentum, liver, and spleen, and to demonstrate that the pro/pre-B cell compartment (CD24+, sIgM-) is detected in the...

Problem statement: Esophageal surgery is associated with greater wound healing problems than surgery on other portion of the alimentary tract. Omentum and fresh bone marrow are rich source of angiogenic factors that promote the growth of blood vessels into wound tissue. The aim of this study was evaluation of the effects of a combination of autogenous fresh bone marrow and omental free graft in...

BACKGROUND The influence of an omentectomy on peritoneal defense mechanisms and its clinical consequences have not been fully elucidated. In the present study, we aimed to investigate the influence of omentectomy on bacterial growth in blood and tissue specimen cultures in rats with experimental peritonitis. METHODS Fifty Wistar-Albino rats were included in the present study. Animals were ass...

Autogenous splenic implant seems to be the only alternative for preservation of splenic tissue after total splenectomy. This work was carried out to analyze the morphologic regeneration of autotransplanted splenic tissue in Wistar rats and to determine the bacterial phagocytic function of their macrophages. We utilized an experimental model with thirty-two rats, of both sexes, submitted to tota...

Contrary to metastatic tumors of the omentum, primary tumors of the omentum are very rare. A 10-year-old girl presented with low abdominal pain. Imaging studies showed a multiseptated hemorrhagic tumor. The mass from the omentum was removed completely and confirmed as a malignant rhabdoid tumor. Despite aggressive chemotherapy, she died after 9 months due to disease progression. We report one c...

There are many techniques have been used in the surgical treatment of prostatitis, prostatic abscesses and prostatic cysts. Partial or complete prostatectomy, marsupialization, or debridement and drainage have all been advocated; unfortunately all of these techniques are associated with complications such as incontinence, cyst or abscess recurrence, etc. More recently, prostatic omentalization ...
