Data on their minimally invasive resection are scarce and the optimal surgical approach for tumors below S3 remains debated.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>We performed a retrospective review of consecutive patients who underwent minimally invasive resection of retrorectal tumors between 2005 and 2022 at two tertiary university hospital centers, by comparing the results obtained for lesions located above or below S3.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Of over 41 patients identified with retrorectal tumors, surgical approach was minimally invasive for 23 patients, with laparoscopy alone in 19, with transanal excision in 2, and with combined approach in 2. Retrorectal tumor was above S3 in 11 patients (&gt;\u2009S3 group) and below S3 in 12 patients (&lt;\u2009S3 group). Patient characteristics and median tumor size were not significantly different between the two groups (60 vs 67\u00a0mm; <jats:italic>p<\/jats:italic>\u2009=\u20090.975). Overall median operative time was 131.5\u00a0min and conversion rate was 13% without significant difference between the two groups (126 vs 197\u00a0min and 18% vs 8%, respectively; <jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05). Final pathology was tailgut cyst (48%), schwannoma (22%), neural origin tumor (17%), gastrointestinal stromal tumor (4%), and other (19%). The 90-day complication rates were 27% and 58% in the &gt;\u2009S3 and &lt;\u2009S3 groups, respectively, without severe morbidity or mortality. After a median follow-up of 3.3\u00a0years, no recurrence was observed in both groups. Three patients presented chronic pain, three anal dysfunction, and three urinary dysfunction. All were successfully managed without reintervention.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Minimally invasive surgery for retrorectal tumors can be performed safely and effectively with low morbidity and no mortality.
