Peritonitis Due to Appendicitis Related to Mercury Sequestration: An Unusual Peruvian Case Report

Abstract

Elemental mercury ingestion caused by folk practices is rare and usually harmless. Nevertheless, some complications related to mercury ingestion have been reported such as appendicitis related to mercury sequestration and poisoning leading to systemic toxicity. Patients usually present with nausea, vomiting, and abdominal tenderness. Mercury sequestration in the appendix depends on its anatomy and mercury physical properties, both of which may lead to appendicitis, resulting in subsequent peritonitis leading to multiple and severe surgical complications. A 26-year-old Peruvian man complaining of vomiting and abdominal pain after ingestion of elemental mercury as part of a folk practice presented to the emergency department. Physical exam was remarkable for rigid abdomen and diffuse rebound sign. A clinical diagnosis of peritonitis was made. The patient was taken to the operating room where an open appendectomy and peritoneal lavage were performed. On gross inspection, a silver foreign body within the perforated appendix was seen by the surgical team. The patient developed multiple surgical complications leading to multiple organ failure and death. Clinicians should be aware that mercury ingestion is usually benign. However, severe complications may develop. Early surgical and medical intervention should be initiated promptly to achieve better outcomes. We present the first case of peritonitis due to appendicitis related to mercury sequestration in the appendix.

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

“…1 Additionally, the surgical team must have extensive experience, and few reports describe the surgical procedure for mercury sequestration in the appendix. 3,7 Here, we report a case of elemental mercury sequestration in the appendix that was successfully managed using laparoscopic appendectomy. We describe the operative techniques, which may help improve the surgical success rate.…”
