Robotic-assisted low anterior resection for rectal cancer shows similar clinical efficacy to laparoscopic surgery: A propensity score matched study

Table 4 Subgroup analysis of anastomotic leakage, n (%)

	Anastomotic leakage	P value
BMI ≥ 25 (kg/m2)		0.428
RALAR (n = 45)	8 (17.8)
LALAR (n = 50)	6 (12.0)
Maximum tumor diameter ≥ 6 cm		0.3301
RALAR (n = 14)	4 (28.6)
LALAR (n = 12)	1 (8.3)

¹Fisher’s exact test.

RALAR: Robot-assisted low anterior resection; LALAR: Laparoscopic-assisted low anterior resection; BMI: Body mass index.
