NCT01997684

Brief Summary

The use of colonic stenting with elective surgery has been suggested as an alternative management for acute malignant colonic obstruction, as emergency surgery has a high risk of morbidity and mortality. However, the available body of literature addressing their benefit in this setting is contradictory. The purpose of this study is to determine the efficacy and safety of colonic stenting with elective surgery versus emergency surgery in the management of acute malignant colonic obstruction.

Outcome Measures

Primary Outcomes (1)

  • Rates of primary colorectal anastomosis

Secondary Outcomes (8)

  • Stoma rates

    From date of randomization until the follow-up ended, assessed up to 2 years

  • Mortality

    From date of randomization until the date of death from any cause, assessed up to 2 years

  • Procedure related complication

    From date of randomization until the first follow-up ended, assessed up to 30 days

  • Re-operation rates

    From date of randomization until the follow-up ended, assessed up to 2 years

  • R0 resection

    From date of randomization until the first follow-up ended, assessed up to 30 days

  • +3 more secondary outcomes

Other Outcomes (2)

  • Technical success

    From date of randomization until the first follow-up ended, assessed up to 30 days

  • Clinical success

    From date of randomization until the first follow-up ended, assessed up to 30 days

Study Arms (2)

Colonic Stenting with Elective Surgery

EXPERIMENTAL

In the experimental group, the patients will undergo colonic stenting within 24 h of inclusion. For this study, the WallFlex â„¢ Colonic Stent (Boston Scientific, Natick, MA) will be employed. Candidates for elective surgery, after clinical success of colonic stenting, will be preferably operated on 5-14 days after inclusion, and no later than 4 weeks. Type and extent of the elective surgery will be selected by the surgeon. In this group, unplanned emergency surgery will be indicated in case of technical failure of colonic stenting, iatrogenic morbidity, or clinical failure. In case of a primary colostomy, restoration of bowel continuity was attempted within 3-6 months.

Procedure: Colonic Stenting with Elective Surgery

Emergency Surgery

ACTIVE COMPARATOR

In the comparator group, patients will be undergo emergency surgery. Surgical options including but not limited to: loop colostomy, Hartmann's procedure, and (sub) total colectomy with ileostomy or ileorectal anastomosis. In case of a primary colostomy, restoration of bowel continuity was attempted within 3-6 months.

Procedure: Emergency Surgery

Interventions

After preparation of the distal colon with an enema, the colonoscope will be introduced up to the site of the obstruction. The colonic stent will be placed along a guide wire through the lesion under radiologic or endoscopic guidance. A colonic stent will be chosen which was at least 3 cm longer than the lesion (1.5 cm at either end). When the colonic stent did not cover the entire length of the lesion, a second overlapping stent will be placed. If the colonic stenting failed (technical failure) or symptoms of colonic obstruction did not resolve within 3 days (clinical failure), patients were indicated for emergency surgery. Candidates for elective surgery were preferably operated on 5-14 days after colonic stenting, and no later than 4 weeks. Type and extent of the surgery were selected by the surgeon, including but not limited to: loop colostomy, Hartmann's procedure, and (sub) total colectomy with ileostomy or ileorectal anastomosis.

Colonic Stenting with Elective Surgery

Type and extent of the surgery were selected by the surgeon, including but not limited to: loop colostomy, Hartmann's procedure, and (sub) total colectomy with ileostomy or ileorectal anastomosis.
