Acute peritonitis secondary to post-traumatic appendicitis: A case report and literature review

BACKGROUND: Blunt abdominal trauma has rarely been reported as a cause of acute appendicitis in the literature. However, the coexistence of the two conditions can cause issues for the patient. We present here a systematic review of cases of traumatic appendicitis as well as our own experience with a 12-year-old male patient. CASE SUMMARY: A 12-year-old male was admitted 3 d after abdominal trauma, experiencing peritoneal syndrome. A pelvic formation was discovered during abdominal ultrasound, and surgical exploration revealed a perforated appendix. A literature review was conducted applying the keywords “appendicitis,” “abdominal,” and “trauma” to the PubMed, Embase, and Medline databases. Our initial search included 529 papers published between 1991 and 2022, of which 33 papers were finally included. They revealed 51 reported cases. The trauma mechanisms included road traffic accidents, falls, assaults, ball accidents, a horse kick, and a colonoscopy. Eight patients underwent surgical exploration with no prior radiological investigation, and twenty-six patients underwent an initial radiological examination. All reports indicated a perforated appendix. CONCLUSION: Acute traumatic appendicitis represents a diagnostic quandary that can be misdiagnosed resulting in significant morbidity and potential mortality. A high level of suspicion combined with radiological examination may aid in the diagnosis and treatment of this condition.
