Data Collected
All data concerning patients’ demographics, such as age,
sex were collected. The intraoperative findings, such as
four quadrant pus, appendicular abscess, and appen-
dicular mass as well as procedure-related complications
were documented. The outcomes, such as relooks, post-
operative complications (see paragraph below) as well as
mortality were recorded.
