Factors Affecting the Choice of Treatment in Hepatic Hydatid Cyst Surgery

Abstract

Objective

We aimed to determine the effective factors in the selection of treatment methods for patients with hepatic hydatid cyst undergoing surgery and the variables effective when performing postoperative endoscopic retrograde cholangiopancreatography (ERCP). In addition, we aimed to reveal the factors affecting the recurrence, postoperative complications, and length of stay of these patients.

Materials and methods

A total of 107 patients diagnosed with hepatic hydatid cysts were treated surgically. Data were obtained from the records of these patients. Chi-square test was used for the analysis. The variables that were found to be significant in the chi-square analysis were included in the logistic regression (Backward: LR) analysis.

Results

Of all patients, 6.5% underwent the puncture, aspiration, injection, and reaspiration (PAIR) technique, 67.3% underwent conservative surgery, and 26.2% underwent radical surgical treatment. In paired comparisons, a significant difference was found among the ultrasonographic size of the cyst (p = 0.033), the radiological classification of the cyst (0.006), and history of previous surgery and treatment methods for the cyst. The risk of performing ERCP was 25.710 [95% confidence interval (CI): 1.721–284.013] folds higher for cysts located in the left lobe, whereas it was 19.992 (95% CI: 2.004–199.488) folds higher for cysts located in both right and left lobes. When the radical surgical treatment method was taken as a reference, the status of ERCP implementation was 29.785 (95% CI: 1.844–480.996) folds higher for PAIR and 3.628 (95% CI: 0.355–37.103) folds higher for conservative surgery.

Conclusion

In conclusion, radical surgery is a significant treatment for hepatic hydatid cyst as its ultrasonographic cyst size increases with time. The location and treatment method of the cyst increases the complication of biliary fistula and requires ERCP.
