Preoperative colonoscopy and postoperative colonoscopic surveillance are essential in identifying patients at risk of metachronous colorectal cancer. A total colectomy and ileorectal anastomosis should be considered for some patients, certainly for those with HNPCC.
VRR is a new approach to the treatment of idiopathic megarectum. Clinical and physiological studies confirm that it can improve sensory feedback and defaecation. The procedure needs further evaluation as the number of patients undergoing the procedure increases.
Acute necrosis of the ileoanal pouch caused by long-axis rotational volvulus is an important, but uncommon, cause of life-threatening acute abdomen after restorative proctocolectomy. Prophylactic pouchpexy at the time of pouch construction or salvage pouchpexy after early diagnosis of the at-risk pouch are important considerations to avoid loss of the pouch.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
