A prospective observational study to assess the energy needs of Ulcerative Colitis patients undergoing total proctocolectomy with ileoanal j-pouch anastomosis.
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.
Study Type
OBSERVATIONAL
Enrollment
30
Resting energy expenditure measurement
Evangelismos General Hospital of Athens
Athens, Attica, Greece
Amount of resting energy expenditure (kcal/day)
To evaluate total energy needs of patients who undergo proctocolectomy with ileoanal j-pouch
Time frame: Before surgery, 1 week postoperatively, 3 months postoperatively
IBDQ
Inflammatory Bowel Disease Questionnaires (IBDQ), a widely used questionnaire for HRQoL assessment in patients with inflammatory bowel diseases (IBDs)
Time frame: Before surgery and 1 week after Surgery
Resting energy expenditure change (kcal/day)
Changes in daily energy expenditure after surgery compared to pre surgery assesment.
Time frame: 1 week postoperatively and 3 months postoperatively
Bristol stool form scale, min: type 1 (hard solid stools, better outcome) - max: type 7 (liquid stools, worst outcome)
Longitudinal changes in Bristol stool form scale score before and after surgery.
Time frame: Before surgery, 1 week postoperatively, 6 months after surgery
Post operative weight loss
Post operative weight loss will be assessed by measuring the post weight on the date of surgery and adjusting for the baseline weight in kg.
Time frame: 1 week postoperatively, 3 months postoperatively
Post operative Energy intake.
Total energy intake measured in calories after surgery.
Time frame: 1 week postoperatively, 3 months postoperatively
