Comment on Evaluating Giant Hydatid Cysts: Factors Affecting Mortality and Morbidity.

they have not given neoadjuvant albendazole treatment. The authors stated that they have used Student’s t-test, Mann–Whitney U test, and Kruskal–Wallis test for comparison of the continuous variables. Since there are no three or more groups for comparison, Kruskal– Wallis test could not have been performed. Further-more, the mean and standard deviation is very close to each other for the continuous variables which means they are not distributing normally. For this reason, Student’s t-test cannot be used and the continuous variables should be expressed as median (min-max) or median (interquartile range [IQR]). In the first sentence of the results section, the authors stated that “a total of 382 patients (145 females and 138 males) were included in the study.” Instead of 382, it should be corrected as “283 patients.” In the results section, the authors stated that “postop-erative recurrence occurred in eight patients (2.8%), all of whom had undergone thoracotomy. Recurrence was attributed to continued exposure to animals.” The main factor that causes a recurrence is remnant germinant membrane due to inadequate surgery. Therefore, this statement is not compatible with current literature. The authors should provide the studies that they have used to support their statement.
