NCT04012645

Brief Summary

It is a multicenter, prospective, and randomized controlled clinical study of patients with mid- or low- rectal cancer who received laparoscopic TME surgery aims to explore whether the application of near infrared-indocyanine green imaging system can evaluate the anastomotic blood perfusion accurately, and optimize the surgical procedures, or even reduce the incidence rates of postoperative anastomotic leakage in mid- or low- rectal cancer patients.

Outcome Measures

Primary Outcomes (1)

  • Anastomotic leakage

    Anastomotic leakage occured within 30 days after operation. The diagnostic criteria for AL include: Flow of gas, abscess, or excrement from pelvic drainage tube, surgical incision or vagina; Accompanied by fever, peritonitis and other systemic symptoms; And AL confirmed by digestive tract radiography, CT scan or enteroscopy.

    within 30 days after operation

Secondary Outcomes (1)

  • the change of surgical precedure

    within the operation time

Study Arms (2)

experimental group

EXPERIMENTAL

Underwent laparoscopic TME and colon-rectum or colon-anal anastomosis. near infrared-indocyanine green imaging system was used during the surgeries.

Procedure: application of near infrared-indocyanine green imaging system

control group

ACTIVE COMPARATOR

Underwent laparoscopic TME operation, and the operator judged anastomotic blood supply with naked eyes and performed the surgical intervention based on the experience

Procedure: Non-application of near infrared-indocyanine green imaging system

Interventions

Underwent laparoscopic TME and colon-rectum or colon-anal anastomosis. near infrared-indocyanine green imaging system was used to evaluate the anastomotic flood perfusion during the operation; The operator may decide whether to change the surgical programme based on the outcome of the evaluation.
