Leech in the Rectum Causing Lower GI Bleeding in a Four Years Old Child: A Case Report

Area of Science:

• Zoology
• Parasitology
• Clinical Medicine

Background:

• Leeches (class Hirudinea) are annelids that parasitize various hosts, including humans.
• These ectoparasites are known for their blood-feeding habits, consuming volumes significantly larger than their own body weight.
• Leech infestations can occur in various human body sites, including the eyes, respiratory tract, urogenital tract, and occasionally the rectum.

Observation:

• A case study involved a four-year-old male child presenting with two weeks of painless, bright red rectal bleeding.
• The child's hematocrit level was 9.2%, indicating significant blood loss.
• A leech was successfully removed from the patient's rectum by immersing the child in water.

Findings:

• The case highlights a rare presentation of rectal leech infestation in a pediatric patient.
• Painless hematochezia in children can be a symptom of internal leech infestation.
• Simple, non-invasive methods can be effective for leech removal.

Implications:

• Pediatricians and emergency physicians should include leech infestation in the differential diagnosis for unexplained rectal bleeding in children.
• Early diagnosis and removal of rectal leeches are crucial to prevent complications such as anemia.
• Awareness of potential leech habitats and transmission routes is important for public health education.
