Evaluation of the effect of pulmonary hydatid cyst location on the surgical technique approaches.
OBJECTIVE
A hydatid cyst is the most common lung parasitic disease and is endemic in Iran. A hydatid cyst is more common in the right lung and lower lobes.


OBJECTIVE
The aim of this study was to assess surgical treatment of pulmonary hydatid cysts and whether the location of cyst affects surgical technique approaches.


METHODS
This study was performed on 87 patients with a pulmonary hydatid cyst who were referred to Qaem Hospital from 2010 to 2012. Selection of surgical technique was according to size, location, and the number of cysts. Patients were divided into two groups: (1) surgery with preserving lung parenchyma and (2) lobectomy. Afterward, the relationship between the location of cyst and surgical technique approaches was evaluated. Data was analyzed by Chi-square and Fisher exact tests.


RESULTS
In this study, no significant relation was found between the size (P = 0.682) and number (P = 0.344) of cysts and lobectomy necessity. But, there was a significant relation between the occurrence of cyst in middle lobe and lobectomy necessity (P = 0.016).


CONCLUSIONS
According to the results, type of surgical technique does not depend on the size and number of cysts, but it may be related to the location of the cyst and the ratio of lung destruction.
