Background: Multi-drug-resistant bacteria are rarely isolated from patients with acute appendicitis.
Methods: Case report and literature review.
Results: We report an unusual case of post-appendectomy intra-abdominal abscess with intra-
operative cultures that grew multi-drug-resistant Acinetobacter baumannii. An 11–year-old
boy underwent open appendectomy for perforated appendicitis. He developed a superficial
surgical site infection at the Penrose drain site on the seventh postoperative day; cultures grew
multi-drug-resistant Acinetobacter baumannii. A computed tomography scan revealed an intra-
abdominal abscess. Open drainage was performed, and intra-operative cultures grew the
same multi-drug-resistant A. baumannii along with Escherichia coli.
Conclusions: Post-operative therapy with ceftriaxone may have predisposed the patient to
nosocomial infection caused by multi-drug-resistant A. baumannii.
