Closed Cyst Resection for Liver Hydatid Disease: a New Standard.

BACKGROUND

Although radical resections are recommended for the surgical management of liver hydatid disease (LHD), whether closed (CCR) or opened (OCR) cyst resections should be performed remains unclear. The aim of this study was to compare the postoperative and long-term outcomes of CCR and OCR for primary and recurrent LHD.

MATERIALS AND METHODS

Medical charts of patients who underwent surgery at a single centre were retrospectively reviewed and compared with respect to major postoperative complications and recurrence rates.

RESULTS

Seventy-nine CCRs and 37 OCRs were included. The major morbidity rates were 19% and 5% in the OCR and CCR groups, respectively (P = 0.036). In multivariate analysis, OCR (P = 0.030, OR = 5.37) and the operative time (P < 0.001, OR = 18.88) were the only independent predictors of major complications. The 5-year and 10-year recurrence rates were both 0% in the CCR group compared to 18% and 27%, respectively, in the OCR group (P < 0.001). The mean time to recurrence was 10.5 (± 8) years.

DISCUSSION

Closed cyst resection for LHD is a safe and effective approach with a low risk of recurrence. Considering that recurrence could appear more than 10 years after surgery, follow-up of patients should be adapted.
