The incision length, in the centimeters, was the exposure. The primary outcome measures were the PPOI incidence and its association with the incision length. The secondary outcome included the days to the first passage of flatus and the days to the first passage of stool.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Overall, 1,840 patients, including 287 (15.7%) patients with the PPOI, were recruited. The PPOI incidence was 17.6% and 13.3% in the long-incision (&amp;gt;18 cm) and short-incision patients ( \u2264 18 cm), respectively. The incidence of the PPOI increased by 1.1% (1.0\u20131.1) by each centimeter increment of the incision length after adjusting for the confounding factors. In comparison to the short-incision patients, the long-incision patients had prolonged passage of stool (4.46 vs. 4.95 days, <jats:italic>p<\/jats:italic> &amp;lt; 0.001). Each centimeter increment of the incision length contributed to a 2% increased risk of delay in the first bowel movement [hazard ratio (HR) 0.980 (0.967, 0.994)].<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> A long abdominal incision length independently contributed to the prolonged gut function recovery post-operatively mainly by delaying the
