Summary
Colonoscopy can rarely cause hemoperitoneum, a serious complication. This case highlights a unique mesocolon laceration, emphasizing the need to consider internal bleeding in persistent post-procedure abdominal pain.
Area of Science:
- Gastroenterology
- Surgical Complications
- Abdominal Imaging
Background:
- Colonoscopy is a common diagnostic and therapeutic procedure.
- While generally safe, potential complications include bleeding and perforation.
- Hemoperitoneum is a rare but severe complication following colonoscopy.
Observation:
- A 20-year-old male presented with left lower quadrant pain post-colonoscopy.
- Abdominal CT scan confirmed hemoperitoneum.
- Urgent laparoscopic exploration revealed a lacerated mesocolon of the descending colon.
Findings:
- The bleeding from the mesocolon laceration was successfully controlled laparoscopically.
- The patient experienced a full recovery without recurrent bleeding.
- This represents a rare instance of isolated mesocolic injury after colonoscopy.
Implications:
- Persistent abdominal pain after colonoscopy warrants consideration of hemoperitoneum.
- Mesocolon laceration is a potential cause of hemoperitoneum post-colonoscopy.
- This case expands the understanding of rare colonoscopic complications.

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
