Strictly-controlled techniques are required in laparoscopic appendectomy for elemental mercury sequestration in the appendix: a case report

Elemental mercury impaction in the appendix can cause subsequent local and systemic complications. We present a case of a teenage boy who ingested approximately 10 mL of elemental mercury, resulting in residual mercury sequestration in the appendix after conservative management. We performed laparoscopic appendectomy to remove the residual mercury. The patient made a complete clinical recovery without adverse events related to mercury poisoning over the 6-month follow-up. We highlight the advantages of laparoscopic appendectomy, abdominal computed tomography (CT), negative pressure operating rooms, and surgeon protection to improve surgical success rates. This case report adds to the literature on the management of elemental mercury impaction in the appendix and provides valuable insights for clinical decision-making.
