Comparative efficacy analysis of laparoscopic-assisted transanal total mesorectal excision vs laparoscopic transanal mesorectal excision for low-lying rectal cancer

Figure 1 Comparison of anal function recovery. A: Comparison of anal resting pressure values; B: Comparison of maximum systolic pressure values; C: Comparison of maximum tolerated volume values; D: Comparison of Memorial Sloan Kettering Cancer Center scores. ^aP < 0.05 compared within the group preoperatively and postoperatively. ^bP < 0.05 compared with the laparoscopic total mesorectal excision group during the same period. ARP: Anal resting pressure; MSP: Maximum systolic pressure; MTV: Maximum tolerated volume; MSKCC: Memorial Sloan Kettering Cancer Center; LapTEM: Laparoscopic total mesorectal excision; TaTME: Transanal total mesorectal excision.
