Strictly-controlled techniques are required in laparoscopic appendectomy for elemental mercury sequestration in the...

Area of Science:

• Toxicology
• Gastroenterology
• Surgical Innovation

Background:

• Elemental mercury ingestion can lead to appendiceal impaction.
• Appendiceal mercury sequestration poses risks of local and systemic complications.
• Conservative management may not always resolve appendiceal mercury impaction.

Observation:

• A teenage male ingested approximately 10 mL of elemental mercury.
• Residual mercury was found sequestered in the appendix after initial conservative management.
• Abdominal computed tomography (CT) was utilized for diagnosis.

Findings:

• Laparoscopic appendectomy was performed to remove the residual appendiceal mercury.
• The patient experienced a complete clinical recovery.
• No adverse events related to mercury poisoning were observed during a 6-month follow-up.

Implications:

• Laparoscopic appendectomy is an effective treatment for appendiceal mercury impaction.
• Utilizing advanced imaging like CT and specialized operating room conditions enhances surgical outcomes.
• This case underscores the importance of surgical intervention for persistent appendiceal mercury sequestration.
