RESUMO
The abdominoperineal excision (APE) is still one of the standard operations for low rectal cancer. The exralevator APE can reduce the positive rate of circumferential margin and perforation rate of rectal cancer, but the incidence of postoperative complications is relatively high. With the continuous development of minimally invasive surgery, the transperineal minimally invasive Abdominoperineal excision (Tpm-APE) is proposed. Compared with traditional APE, the Tpm-APE has potential technical advantages, but there is a lack of large sample and multicenter clinical research evidence. The authors share the design and results of an international multicenter clinical study to investigate the clinical practice of Tpm-APE in the treatment of low rectal cancer.
