Table 3.

Correlation between results of radiological examination of the anastomosis and the presence or absence of clinical anastomotic leakage for each imaging modality separately and for the whole group of patients (only contrast radiography in 40, only CT in 27, and both imaging modalities in 24 patients)

	Clinical anastomotic leakage		Sensitivity % (CI)	Negative predictive value % (CI)
	Yes	No	Sensitivity % (CI)	Negative predictive value % (CI)
All patients (N = 91)			65 (51–79)	73 (61–84)
Leakage^a	28	8^b
No leakage	15	40
Contrast radiography (N = 64)			68 (51–84)	76 (62–89)
Leakage	21	2^c
No leakage	10	31
CT(N=51)			54 (34–74)	66 (49–82)
Leakage	13	6^d
No leakage	11	21

CI = 95% confidence interval

^aFive patients with leakage by only one of both imaging modalities

^bThree negative relaparotomy

^cOne negative relaparotomy

^dTwo negative relaparotomy
