Incidence, outcomes, and risk factors of postlaparoscopic subcutaneous emphysema: a historical cohort study
Authors' conclusion
This historical cohort study showed a relatively high incidence of postlaparoscopic subcutaneous emphysema. In addition to previously reported risk factors, female sex and use of the AirSeal Intelligent Flow System were found to be associated with postlaparoscopic subcutaneous emphysema.
