To comparatively evaluate Seldinger and Trocar techniques in the percutaneous treatment of hydatid disease.
Trocar and Seldinger techniques were used for 49 and 56 cysts, respectively, among 106 hydatid cysts in 88 patients. The number of males and females were 22 and 66, respectively with a mean age of 44.9 years (range, 15-87). Follow-up studies included cyst diameter, cyst contents, and morphological changes in the cyst wall, local recurrence, and secondary invasion, using ultrasound, computerized tomography and chest X-rays.
The positive criteria of healing were a decrease in cyst diameter, progressive solidification of the cyst contents, and disappearance of the cyst. Local recurrence was defined as an increase in the cyst diameter and contents, and appearance of daughter cysts in the primary cavity, while secondary dissemination was defined as the appearance of new cysts outside the treated cyst. Mean duration of follow-up was 19.23 mo (range, 18-26 mo). Follow-up results demonstrated that no significant differences were present between the Trocar and Seldinger techniques in the percentage of decrease in the cyst volume, rate of early complications, local recurrence and secondary dissemination (P = 0.384, 0.069, 0.215 and 0.533, respectively).
There are no differences between the Seldinger and Trocar techniques that gain entry to the cyst cavity in terms of the efficacy of the treatment and the rates of early and late complications.
Core tip: Although various methods have been developed as interventional procedures, there is no knowledge in the literature on which technique should be used when entering the cyst hydatid cavity. İn this study, no differences have been found between the Seldinger and Trocar techniques that gain entry to the cyst hydatid cavity in terms of the efficacy of the treatment and the rates of early and late complications. Although trocar technique is a practical method that is easier and more economical to apply compared with the drainage procedure conducted using Seldinger technique, it should not be considered in post-surgical and elderly patients.
