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.

Figure 2 Comparison of surgical stress response factors. A: Comparison of cortisol levels; B: Comparison of adrenaline levels; C: Comparison of norepinephrine levels. ^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. Cor: Cortisol; AD: Adrenaline; NE: Norepinephrine; LapTEM: Laparoscopic total mesorectal excision; TaTME: Transanal total mesorectal excision.

Figure 3 Comparison of quality of life. A: Comparison of cognitive function; B: Comparison of physical function; C: Comparison of emotional function; D: Comparison of role function. ^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. LapTEM: Laparoscopic total mesorectal excision; TaTME: Transanal total mesorectal excision.
