Correlation of radiological findings with surgical findings in hepatic hydatid disease. A prospective study of 79 cases.

OBJECTIVES

The liver is the most frequent anatomic location of hydatid disease. Imaging modality nowadays are numerous and increasingly efficient. The objective of our study is to precise the correlation between Ultrasonography, computed tomography and intraoperative findings on the different characteristics of hepatic hydatid cyst.

PATIENTS AND

METHODS

We conducted a prospective study including all hepatic hydatid cyst operated in 2015. We evaluated statistically, by calculating the coefficient K or the intraclass correlation coefficient, the concordance between Ultrasonography, computed tomography (CT) and intraoperative findings on the different characteristics of hepatic hydatid cyst.

RESULTS

In our study, we included 48 patients with 79 hepatic hydatid cysts. It was concluded that Ultrasonography performs better than CT in the study of type of cyst, pericyst, relationships with portal vein and main bile duct. While CT is better than echography in terms of number, localizations of cyst, relationship with the vena cava inferior, other localizations and the remaining liver, both examinations remain limited in the determination of pericyst characteristics and the identification of biliary fistula.

CONCLUSION

Ultrasonography and CT cannot provide accurate data for the study of pericyst and biliary fistula, hence requiring prospective studies of the place of MRI and intraoperative echography in this domain.
