Localized diagnosis and surgical management of insulinoma / 中国实用外科杂志

Insulinoma is a type of functional pancreatic neuroendocrine neoplasms(p NENs).As symptoms of hypoglycemia due to hyperinsulinemia are varied and nonspecific,diagnosis of insulinoma tends to be quite difficult.Both of localization diagnosis and surgical management are key points to deal with insulinoma.As for localization,while traditional imaging methods like CT and MRI improve quite fast,new molecular imaging technologies also develop rapidly.In terms of surgical treatment,main concerns of physicians often focus on the evaluation of operative procedures and experience of operating points.

CT Localized Diagnosis of Primary Mesenteric Occupancy Lesions / 实用放射学杂志

Objective To evaluate the value of CT examination in localized diagnosis of primary mesenteric occupancy lesions.Methods CT findings in 35 cases of primary mesenteric occupancy lesions proved operatively and pathologically were analysed.Results Accuracy and postive forecast rate of localization of lesions by CT were 62.9% and 78.6% respectively.The findings of localized diagnosis included:(1)The relation between the occupancy lesions and intestines was closed,the situs was circled by intestines which were fixed and there was no filling defect in 25 cases.(2)The main retroperitoneal organs were distorted and their axes were rotated by the lesions in 15 cases.(3)There was fat space between the lesions and the retroperitoneal organs and the abdomen walls in 11 cases.(4)The main blood vessels of abdomen were compressed by the lesions or the lesions circled by vessels in 9 cases.The localized accuracy was lower when the lesions were larger.Conclusion CT is useful for localization of primary mesenteric occupancy lesions.CT combined with other imaging data and clinical symptoms can improve CT localized accuracy.
