Transmural coil extrusion after embolization for colonic hemorrhage

Area of Science:

• Gastroenterology
• Interventional Radiology
• Endoscopy

Background:

• Transcatheter embolization is a common treatment for acute lower gastrointestinal hemorrhage.
• The long-term fate of embolization coils within the colon is not well-documented.
• Complications or unusual findings related to embolization coils require further investigation.

Purpose of the Study:

• To report a case of partially extruded embolization coils found during colonoscopy.
• To highlight the potential for misidentification of these coils.
• To raise awareness about this uncommon endoscopic finding.

Main Methods:

• A case report of a patient with massive descending colonic bleeding.
• Successful treatment with transcatheter microcoil embolization.
• Follow-up colonoscopy revealing partially extruded coils.

Main Results:

• The patient's bleeding was successfully controlled with microcoil embolization.
• During colonoscopy, partially extruded coils were visualized.
• The coils were initially misidentified as ingested foreign material, such as jewelry.

Conclusions:

• Partially extruded embolization coils can be an endoscopically enigmatic finding.
• While potentially confusing, this finding may be clinically inconsequential in some cases.
• Further studies are needed to determine the incidence and clinical significance of extruded coils after transcatheter embolization.
