Curved plannar reconstruction with maximum intensity projection in lower gastrointestinal bleeding

Area of Science:

• Gastroenterology
• Medical Imaging
• Surgical Endoscopy

Background:

• Hematochezia, or rectal bleeding, can indicate various lower gastrointestinal pathologies.
• Large colonic polyps are a common cause of lower GI bleeding and require timely diagnosis and management.

Observation:

• A 51-year-old male presented with acute hematochezia.
• Abdominal CT and colonic imaging revealed a large, high-density lesion in the ascending colon.
• Colonoscopy confirmed a 4 cm bleeding polypoid eminence in the ascending colon.

Findings:

• The polypoid lesion in the ascending colon was identified as the source of bleeding.
• Endoscopic mucosal resection (EMR) was performed to remove the polyp.
• The patient experienced complete resolution of hematochezia post-procedure.

Implications:

• EMR is an effective and minimally invasive treatment for large, bleeding colonic polyps.
• Prompt diagnosis via imaging and endoscopy is crucial for managing acute lower GI bleeding.
• This case highlights the importance of endoscopic intervention for polypoid lesions causing significant hematochezia.
