Comparative StudyGlasgow coma scale and APACHE II system data--are they normally distributed?
To verify whether the Glasgow Coma Scale (GCS) and APACHE II system scores are normally distributed. ⋯ We demonstrated that GCS data do not follow the normal distribution, and thus nonparametric tests should be employed when dealing with such data. Furthermore, APACHE II data follow the normal distribution, and parametric tests could be considered, even though nonparametric tests are still preferred.

Mediastinoscopy has the potential to bring under view the upper mediastinum, the area most difficult to dissect during transhiatal esophagectomy. The aim of the present study was to evaluate in an animal model the feasibility of the gas-chamber mediastinoscopy technique for dissection of the upper esophagus. ⋯ The technique of gas-chamber mediastinoscopy is feasible. It allows a fair amount of freedom of movement for the working instruments and offers a good view on the operative field for a controlled and accurate dissection. Further evaluation in experimental and clinical studies is required to establish the role of this procedure in esophageal surgery.
