Summary
Brief summary
The PIPA trial is a prospective, multicentre, cluster randomized cluster crossover non-inferiority study. We aim to test whether a three-day postoperative course of per oral antibiotics is non-inferior to a three-day postoperative course of intravenous antibiotics as standard care after laparoscopic surgery for complicated appendicitis in regards to the risk of postoperative intraabdominal abscess formation within 30-days
