Answer

In 2016, the US Multi-Society Task Force on Colorectal Cancer issued guidelines on colonoscopy after colorectal cancer resection, which included the following recommendations [26] :

  • Patients with colorectal cancer (CRC) should undergo high-quality perioperative clearing with colonoscopy. The procedure should be performed preoperatively, or within a 3- to 6-mo interval after surgery in the case of obstructive CRC. The goals of perioperative clearing colonoscopy are detection of synchronous cancer and detection and complete resection of precancerous polyps.
  • Patients who have undergone curative resection of either colon or rectal cancer should receive their first surveillance colonoscopy 1 yr after surgery (or 1 yr after the clearing perioperative colonoscopy).
  • Patients with localized rectal cancer who have undergone surgery without total mesorectal excision, those who have undergone transanal local excision (ie, transanal excision or transanal endoscopic microsurgery) or endoscopic submucosal dissection, and those with locally advanced rectal cancer who did not receive neoadjuvant chemoradiation and then surgery using total mesorectal excision techniques, are at increased risk for local recurrence. In these situations, it is suggested that patients undergo local surveillance with flexible sigmoidoscopy or endoscopic ultrasound (EUS) every 3−6 mo for the first 2−3 yr after surgery. These surveillance measures are in addition to recommended colonoscopic surveillance for metachronous neoplasia.
  • In patients with obstructive CRC precluding complete colonoscopy, CT colonography (CTC) is recommended as the best alternative to exclude synchronous neoplasms. Double-contrast barium enema is an acceptable alternative if CTC is not available.
