introduction: nitric oxide (no), as a free radical, involves in several physiologic functions in gi tract such as nerve impulse transmission and vascular tonicity regulation. nitric oxide synthase (nos) is the enzyme for the production of no from l-arginine which in turn inhibits by l-ngnitroarginine methyl ester (l-name). in the current work, we aimed to evaluate morphometric analysis of duode...

anatomical variations of duodenum such as atresia, stenosis, and variations in shape have been described by various authors, but the existence of a gross anomaly in shape and position of midgut segment of the duodenum is rare. few reported cases of duodenal anomalies date back to early twentieth century. in the wake of advancement of imaging techniques and minimal access surgeries, authors repo...

peptic ulcer disease and its complications have long been studied but the coexistence of two major complications in a kissing ulcer is uncommon. we present our experience with this entity and review the related literature. a 27 year old man was suffering from concomitant major complication of duodenal kissing ulcer, huge anterior perforation and uncontrolled posterior bleeding, presenting as he...

background: an increase in the number of intraepithelial lymphocytes (iel) in the duodenal mucosa is an important criterion for the histological diagnosis of celiac disease (cd). we determined the normal range for intraepithelial lymphocytes (iel) in the second part of duodenum in healthy iranian population. materials and methods: four biopsy samples of the endoscopically normal appearing mucos...

brunner’s gland hamartoma is a rare benign tumour of the duodenum. it was first described by cruveilhier in 1835. presently around 200 cases have been reported in literature. no sex predilection is seen. patients usually present in the fifth to sixth decades of life. they may be clinically silent or may present with variable symptoms and occasionally obstructive symptoms and chronic pancreatiti...
