Transanal local excision reduces surgical burden without evidence of increased recurrence in lower rectal GIST: a multicenter inverse probability of treatment weighting analysis.

BACKGROUND Lower rectal gastrointestinal stromal tumors (rGISTs) pose a surgical challenge, as complete resection must be balanced against anorectal function preservation. Transanal local excision (taLE) may offer a less invasive alternative to transabdominal laparoscopic radical resection (tlRR), but comparative evide...
