Brief insight regarding the use of transanal, laparoscopic, and robotic total mesorectal excision for rectal cancer

Table 1 Comparison of complications modified, n (%)

Groups	LapTME (n = 44)	TaTME (n = 50)	P value
Anastomotic fistula	1 (2.27)	1 (2.00)
Anastomotic bleeding	3 (6.82)	2 (4.00)
Ileus	3 (6.82)	2 (4.00)
Incision infection	1 (2.27)	0 (0.00)
Total occurrence	8 (18.18)	5 (10.00)	0.252

Comparison of complications modified from Lu et al[8]. LapTME: Laparoscopic total mesorectal excision; TaTME: Transanal total mesorectal excision.
