This multicentre prospective feasibility study evaluated the bedside use of LumenEye® for early inspection of colorectal anastomoses in postoperative patients. The aim was to determine whether digital rectoscopy could safely and accurately detect anastomotic leaks before clinical symptoms developed.
A total of 53 patients from five European centres were included. The LumenEye was used at bedside to assess anastomotic healing, and early leaks were detected in 3 patients — all of whom showed no clinical signs at the time of inspection. The procedure was safe, well tolerated, and had no adverse events.
The authors conclude that bedside LumenEye assessment may enable early leak detection, reduce reliance on CT imaging, and support proactive postoperative decision-making. A larger powered study is recommended to assess sensitivity and specificity.
