Gallbladder ascariasis with uneventful worm migration back to the duodenum: A case report

Area of Science:

• * Parasitology
• * Gastroenterology
• * Infectious Diseases

Background:

• * Ascariasis is a globally prevalent parasitic infection caused by Ascaris lumbricoides, typically residing in the small intestine.
• * While Ascaris can invade bile and pancreatic ducts, gallbladder invasion is uncommon due to the narrow, tortuous cystic duct.

Observation:

• * A rare case of ascariasis involving the gallbladder is presented.
• * The patient exhibited an unusual migration of the Ascaris worm from the gallbladder back into the intestinal lumen.

Findings:

• * The study documents a unique instance of gallbladder ascariasis.
• * The key finding is the rare retrograde migration of Ascaris lumbricoides from the gallbladder to the intestine.

Implications:

• * This case expands the understanding of Ascaris lumbricoides' migratory capabilities and potential complications.
• * Highlights the importance of considering unusual presentations in diagnosing parasitic infections.
• * Contributes to the literature on rare parasitic invasions of the biliary system.
