aim :  this study aimed to compare the recurrence rate, mortality, and morbidity of curative resection of distal adenocarcinoma of the stomach between total gastrectomy (tg) and subtotal gastrectomy (stg). background : the choice between tg and stg for adenocarcinoma of the lower third of the stomach is still a matter of debate and controversy among surgeons. patients and methods : hospital rec...

background : gastric cancer is a common and lethal disease throughout the world. in iran with 7300 new cases annually, it is the first cause of cancer related death in both sexes. regarding the high incidence (10.5/100000 individuals) of gastric can­cer and priority of prevalence index in cancer management, in this study we tried to determine 1, 2-3 and 4-5 year point preva­lence of the disease...

adenosquamous carcinomas of stomach are rare entities comprising 0.5% of stomach carcinomas. here, we report a case of a 50-year-old female, who presented with weakness, pallor, and symptoms of gastric outlet obstruction. a partial gastrectomy was done and histology showed evidence of adenosquamous carcinoma of the antrum with metastasis to the perigastric lymph nodes. the patient condition imp...

up to date, there are four pharmacologically characterized subtypes of muscarinic receptors (m1, m2, m3 and m4). in our study we have investigated muscarinic receptor subtypes in smooth muscle layers of human stomach. isolated preparations of longitudinal and circular muscle layers from human stomach were used. acetylcholine, bethanechol, carbachol, pilocarpine and ahr -602 produced concentrati...

nucleolar organizer regions (nor) are defined as nucleolar components containing a set of argyrophilic proteins which are selectively stained by colloidal silver nitrate staining. although studies have shown that the number of nor dots or particles is directly related to the rapidity of cell proliferation in cancer cells, prognostic or diagnostic value of nor remains controversial. the aim of t...

fibrovascular polyps are rare, pedunculated, tumor-like lesions that are usually found in the esophagus; occurrence in the stomach is very rare. to our knowledge, sonographic and ct findings of a fibrovascular polyp in the stomach have never been reported. here, we report a case of a fibrovascular polyp that was identified in the gastric antrum and prolapsed into the duodenal bulb. sonography r...
