A 58-year-old woman was referred for a follow-up colonoscopy, having been diagnosed with colon cancer eight years earlier which was treated with surgery (sigmoidectomy with end-to-end anastomosis1) and adjuvant chemotherapy (stage pT3N0M02). Two years later, she presented a recurrence of the disease with two lung metastases. The first was treated surgically, and the second was treated with stereotactic body radiation therapy. Two subsequent follow-up endoscopies showed no evidence of disease.

The current colonoscopy found the patient's colonic mucosa to be normal along its entire length (Fig. 1). However, the region of the anastomosis featured a very prominent area of neovascularisation with an arboriform pattern (Figs. 2 and 3), with no other signs of recurrence, ischaemia or recent bleeding. These striking findings were consistent with formation of perianastomotic vessels following surgery. Notably, despite this endoscopic imaging, the patient was asymptomatic, with no gastrointestinal bleeding, abdominal pain or altered bowel movements and no evidence of recurrence on a computed tomography (CT) scan (Fig. 4). One year later, the patient remained asymptomatic and cancer-free.

The presence of vessels in the perianastomotic mucosa is a common finding on endoscopy following colon resection with subsequent anastomosis.3 However, such a prominent neovascularisation with this distribution is exceptional. Despite its striking appearance, this condition is not associated with pathological significance and does not require any subsequent follow-up or treatment.

Ethical considerations

The patient granted her informed consent to the colonoscopy and to the acquisition of images during the test, as well as to the publication of those images deemed of interest by the physicians responsible.

The patient’s identity was kept confidential at all times.

No experiments were conducted in either animals or humans.

Funding

No funding was received for this study.
