- Brief Summary
Our preliminary work demonstrates that there is buy-in from both patients and surgeons with regards to early ileostomy closure (EIC) for select rectal cancer patients undergoing restorative proctectomy (RP) and diverting loop ileostomy (DLI). The feedback from leaders in Europe further supports the need for a large scale randomized-controlled trial (RCT) on this subject in North America. Should the results of such a study be favourable, we believe it could support a change in practice that would be beneficial to patients and the health care system alike. Furthermore, our work will help identify which patients and practices are suitable for EIC.
The goal of our project is to determine whether EIC in rectal cancer patients undergoing RP with a DLI is safe, feasible and beneficial in a North American population. Specifically, our primary objective is to compare the severity of complications between patients undergoing EIC versus traditional (late) closure. Our secondary objectives include assessing the difference in quality of life (QoL), early and late bowel function, and cost of care between these two groups.
- Detailed Description
Eligible adults (≥18 years-old) from one a large colorectal surgery practice in Canada who (1) underwent RP with creation of a DLI for the treatment of rectal cancer and (2) have a negative anastomotic leak test on post-operative day 7-9 which will consist of a flexible sigmoidoscopy and CT scan with rectally-administered water soluble contrast. Patients will be excluded if there is (1) peri-operative immunosuppression, (2) age-adjusted Charlson Comorbidity Index \>6, (3) other major surgery during the index operation, and (4) any major complications (Clavien Dindo Grade III-V) following RP. Eligible participants will be randomized (1:1): Intervention group (EIC): Following a negative leak test, patients will undergo standardized reversal of their DLI (stapled side-side functional end-to end anastomosis, purse-string closure of the ileostomy wound and no use of epidural analgesia) between post-operative days 10-14. Control group (standard practice): Following a negative leak test, patients will undergo a standardized reversal of their DLI no earlier than 12 weeks following their index surgery.
The primary outcome will be comprehensive complication index (CCI) at 12 months following RP. Secondary outcomes will include: CCI at 2-, 6-, and 9-months following RP; recovery from surgery using the PROMIS 29 profile at 7- and 14-days post RP; bowel function, as measured using the Low Anterior Resection Syndrome (LARS) Score at 2-, 6-, 9-, and 12-months post-DLI closure; post-operative ileus, as defined by intolerance to oral intake in the absence of clinical or radiological signs of obstruction, will be measured prospectively after DLI closure; overall QoL, as measured by the EORTC CR30 and QLQ-CR38 at 0-, 2-, 6-, 9-, and 12-months post-RP; cost, as measured from the perspective of the healthcare system \[length of hospital stay (RP, ileostomy closure, and any readmissions), interventions in any setting following RP, and appliance-related costs\] will be assessed at 6- and 12-months post-index surgery. Treatment effect on the primary outcome (CCI at 12 months) will be modeled using linear regression.

Group Intervention Description Early Ileostomy Closure Early Ileostomy Closure Following a negative leak test (CT scan with rectally-administered water-soluble contrast on post-operative day 7, 8 or 9), patients will undergo standardized reversal of their diverting loop ileostomy (stapled side-side functional end-to end anastomosis, purse-string closure of the ileostomy wound, and no use of epidural analgesia) between post-operative days 10-14.
- Primary Outcome Measures
Name Time Method Complications 12-months post-restorative proctectomy Comprehensive complication index
- Secondary Outcome Measures
Name Time Method Complications 2-, 6-, and 9-months post-restorative proctectomy Comprehensive complication index
Occurrence of post-operative ileus following ileostomy reversal Monitored for from date of ileostomy closure to day of discharge from hospital Intolerance to oral intake in the absence of clinical or radiological signs of obstruction, measured prospectively after diverting loop ileostomy closure
EORTC QLQ-CR29 score Baseline (day of patient recruitment), 2-, 6-, 9-, and 12-months post-restorative proctectomy Health-related quality of life of colorectal cancer patients. All of the scale ranges in score from 0 to 100. Higher score for the functioning scales and global health status denote a better level of functioning (i.e. a better state of the patient), while higher scores on the symptom and single-item scales indicate a higher level of symptoms (i.e. a worse state of the patient).
Cost of patient care (in dollars) Calculated at 6- and 12-months post restorative proctectomy Measured from the perspective of the healthcare system, by combining cost of each hospital admission (restorative proctectomy, diverting loop ileostomy closure, and any readmissions), interventions in any setting following restorative proctectomy, and stoma appliance-related costs (measured based on the average number of bags and stoma appliances used per week by each patient).
Post-operative recovery 1- and 2-weeks post-restorative proctectomy and diverting loop ileostomy as well as 30 days post-diverting loop ileostomy closure PROMIS-29 profile v2.0. PROMIS measures use a T-score metric in which 50 is the mean of a relevant reference population and 10 is the standard deviation of that population. For PROMIS measures, higher scores equals more of the concept being measured (e.g., more Fatigue, more Physical Function). Thus a score of 60 is one standard deviation above the average referenced population. This could be a desirable or undesirable outcome, depending upon the concept being measured.
Time to chemotherapy (weeks) Starting from restorative proctectomy post-operative day 1 through the course of the study (1 year follow-up) Number of weeks elapsed from date of restorative proctectomy to date of initiation of adjuvant chemotherapy
Bowel function 2-, 6-, 9-, and 12-months post-diverting loop ileostomy closure Low Anterior Resection Syndrome (LARS) Score. The score ranges from 0-42 with a score of 0-20 representing "No LARS", a score of 21-29 representing "Minor LARS" and a score of 30-42 representing "Major LARS".
EORTC QLQ-C30 score Baseline (day of patient recruitment), 2-, 6-, 9-, and 12-months post-restorative proctectomy Health-related quality of life of cancer patients. All of the scale ranges in score from 0 to 100. Higher score for the functioning scales and global health status denote a better level of functioning (i.e. a better state of the patient), while higher scores on the symptom and single-item scales indicate a higher level of symptoms (i.e. a worse state of the patient).
