Clinical Trial Summary

A prospective observational study to assess the energy needs of Ulcerative Colitis patients undergoing total proctocolectomy with ileoanal j-pouch anastomosis.

Description:

Total proctocolectomy with creation of ileoanal j-pouch anastomosis is the gold-standard surgical procedure for familial polyposis, for ulcerative colitis unresponsive to medication and for colitis associated with dysplasia requiring total colectomy.

Patients postoperatively face difficulties in maintaining their physical condition and quality of life due to potential complications such as surgical, mechanical, inflammatory and functional disorders increasing the rates of malnutrition. Postoperative changes as regards anthropometric characteristics and nutritional status have not been fully elucidated.

Therefore, the need arises to calculate the energy needs of patients with ileoanal j-pouch anastomosis, given the lack of corresponding data and the possible differentiation of energy needs from a similar group of patients undergoing colorectal surgery.

Of particular interest is the body composition of ileoanal anastomosis patients, which has been studied very little ), and the extent to which their energy needs are met, given dietary restrictions both preoperatively and postoperatively.

It is therefore necessary to determine the energy needs, as well as the degree of their coverage by the diet, of UC patients undergoing proctocolectomy with creation of ileoanal j-pouch anastomosis.
