Our local experience with the surgical treatment of ampullary cancer

Table 1 Comparison of different parameters among the different surgical approach groups.

	Whipple's procedure (n = 21)	Local excision (n = 9)	Palliative surgery (n = 2)	p-value
Hospital morbidity
n (%)	6 (28.6)	0 (0)	0 (0)	0.129^a
Hospital stay, days
Median (range)	16 (9–32)	8 (7–10)	7.5 (7–8)	<0.001^b

^a Fisher's exact test
^b Kruskal-Wallis test for the overall comparison (The significant pairwise comparisons with Bonferroni adjusted p-value were Whipple's procedure vs. the other two groups for both the hospital stay and operation time [p < 0.05]).
