Intersphincteric resection with rectal eversion improves anal preservation

A novel surgical technique for low rectal cancer, intersphincteric resection combined with rectal eversion and total extra-abdominal resection (ISrer), shows promise in enhancing anal preservation rates without raising postoperative complications. In a study involving 74 patients, ISrer achieved a 94.3% anal preservation rate compared to 71.8% for conventional laparoscopic ISR, while maintaining a 100% R0 resection rate. The technique demonstrated similar costs and hospital stay duration to traditional methods, marking it as a beneficial alternative.
