BACKGROUND In sentinel node (SN) detection for cases of early gastric cancer, the submucosal dye injection method appears to be more reasonable than the subserosal injection. To compare the two injection methods, we have focused on the rate of concordance between hot nodes (HNs) obtained from the radioisotope (RI) method and green nodes (GNs) obtained from the dye-guided method in addition to t...

Nineteen cases of pneumatosis cystoides intestinalis all affecting adults and all involving the small intestine have been collected in two centres of Iran (Shiraz and Tehran) over a 20 year period, the pathological findings being divided into three groups: pure submucosal, combined submucosal and subserosal, and pure subserosal cysts. Experimental PCI was produced in cadavers using high pressur...

Uterine fibroids are often found in women of reproductive age. Different types of fibroids may affect reproductive outcome to a different extent, with submucous, intramural and subserosal fibroids being (in decreasing order of importance) a cause of infertility and pregnancy wastage. Fibroids may also produce a number of complications during pregnancy. Women who are scheduled for assisted conce...

Parasitic myomas are those that have become partially or almost completely separated from the uterus and receive their main blood-supply from another source. The etiopathogenesis of parasitic myomas may be separation of peduncululated subserosal myomas that have outgrown their blood supply. More commonly, iatrogenic parasitic myomas may be caused by seeding of myoma fragments following morcella...

Omental torsion is a rare cause of acute abdominal pain. It presents with nonspecific symptoms and signs of an acute abdomen, making it difficult to diagnose preoperatively, because symptoms mimic those caused by other conditions such as appendicitis, cholecystitis, diverticulitis, and other gynecologic diseases. Computed tomography is an effective and useful method to diagnose and exclude othe...

Membranous fat necrosis (MFN) in the gallbladder is rare. We found marked MFN as the cause of peculiar foreign body reaction in a Japanese woman in her late seventies, with severe chronic cholecystitis. Histopathological examination of the extirpated gallbladder revealed severe grade chronic cholecystitis accompanied by many multinucleated giant cells and phagocytizing yellowish wavy membranous...
