Few studies on sphincter-preserving surgery have analyzed the colon used for the anastomotic segment. We evaluated the usefulness of measuring the square of the diameter of the sigmoid colon (cm2) (lumen score, LS) as a predictor of defecatory function after very low anterior resection (VLAR) for rectal cancer. Measurements were done by radiography with semiliquid barium, and the LS was calculated...
