Table 3 Postoperative outcomes according to mode of presentation, n (%)

Outcome	Emergency (n = 56)	Elective (n = 96)	P value
Any postoperative complication	28 (50.0)	26 (27.1)	0.008
Major complication (Clavien-Dindo ≥ III)	16 (28.6)	11 (11.5)	0.015
Anastomotic leakage	8 (14.3)	2 (2.1)	0.006
ICU admission	16 (28.6)	6 (6.3)	< 0.001
Length of hospital stay, days, median (IQR)	10 (7-13.3)	6.5 (5-10)	< 0.001
Reoperation	3 (5.4)	0 (0)	0.048
Stoma formation	26 (46.4)	34 (35.4)	0.243
30-day mortality	4 (7.1)	4 (4.2)	0.467

Categorical variables were compared using Pearson χ² or Fisher’s exact test, and continuous variables using the Mann-Whitney U test. ICU: Intensive care unit; IQR: Interquartile range.
