Sigmoid Perforation by an Ingested Foreign Body Mimicking Acute Appendicitis: A Case Report

Lower abdominal pain is a common complaint for patients presenting for evaluation in the emergency department. Among other life-threatening complications, acute appendicitis needs to be ruled out in the case of right-lower quadrant pain (RLQ). Sigmoid perforation caused by an ingested foreign body is an uncommon cause of RLQ pain. This report presents the case of an otherwise healthy, 29-year-old male who presented to the emergency department with RLQ pain. His initial evaluation raised concern for acute appendicitis. However, during his exploratory laparoscopy, he was found to have a perforated sigmoid colon due to a skewer stick; the patient had no recollection of having ingested any foreign body. This paper highlights the importance of considering the possibility of sigmoid perforation by an ingested foreign body as a possible cause of RLQ pain. The article also reviews the most common causes of ingested foreign bodies, their potential complications and management.
