Obstructive Enteropathy

• the resection specimen is dictated by the site and nature of the abnormality and extent of any complications that are present. For example, jejunal ring diaphragm disease results in resection of the radiologically and macroscopically involved segment whereas Crohn's terminal ileitis produces a limited right hemicolectomy. Intussusception complicated by ischaemia needs a more extensive resection than would be otherwise necessary. A cancer operation will necessitate more radical dissection of mesentery and regional lymph nodes. In some instances it is not possible clinically or macroscopically to distinguish between inflammatory and neoplastic ulcers or strictures - handling of the specimen must therefore cover these various options pending histopathological assessment.
