Preoperative predictive factors of recurrent hepatic hydatid cyst after different types of open surgical treatment

Abstract EN

Objective: Hydatid cysts is a parasitic disease of worldwide distribution, continues to be a major public health problem.

The aim of this study was to identify the preoperative predictive factors of recurrence after different types of open surgical treatment for hepatic hydatid cysts.

Methods: A retrospective study of 160 patients who underwent open surgery for hepatic hydatid cysts were included in this study in Mosul and Duhok teaching hospitals, during the period from February 1997 till March 2017.

The patients demographic data, cyst characteristics (location, type, size, and multiplicity), type of operation (endocystectomy and external tube drainage, deroofing with omentoplasty, or total pericystectomy) performed and recurrence rate were recorded.

Mean follow-up period was 30 months (6-180 months).

Results: There were 110 female and 50 male patients with a ratio F/M: 2.2/1.

The age range was 4-70 years.

Right lobe was involved in 123 patients, the left lobe in 22 and both lobes in 15 patients.

Average cyst size in cm was 8.6±2.41 cm.

Single cyst in 116 and multiple cysts in 44 patients.

Univesicular type in 104 and multivesicular in 56 patients.

Recurrence rate was 15.6%, which was detected in patients with multivesicular type and in multiple cysts.

Conclusions: Preoperative predictor factors of recurrence of hepatic hydatid cyst after different types of open surgical treatment according to logistic regression analysis revealed that multiple cysts and multivesicular cysts are independent factors for recurrence, with a p-value of 0.046 and 0.003, respectively
