Colonoscopy polypectomy management in Glanzmann's thrombasthenia.

Area of Science:

• Gastroenterology
• Hematology
• Genetics

Background:

• Glanzmann's thrombasthenia (GT) is a rare autosomal recessive bleeding disorder.
• Platelet dysfunction in GT stems from an abnormal Glycoprotein IIb/IIIa complex.
• Limited data exists on managing colon polyps in GT patients.

Purpose of the Study:

• To describe the endoscopic management of large colon polyps in a patient with Glanzmann's thrombasthenia.
• To evaluate the efficacy of different polypectomy techniques in preventing bleeding in GT.

Main Methods:

• A single patient with Glanzmann's thrombasthenia underwent sequential endoscopic polypectomy for large colon polyps.
• Standard cautery polypectomy was performed, followed by the application of multiple hemostatic clips.
• Bleeding complications were monitored for immediate and delayed post-procedural periods.

Main Results:

• The patient experienced both immediate and delayed bleeding post-polypectomy.
• The preemptive use of multiple hemostatic clips for polyps 10 mm or larger proved most effective in controlling bleeding.
• This approach was superior to other therapeutic interventions in preventing post-polypectomy hemorrhage.

Conclusions:

• Multiple hemostatic clips are recommended for large polypectomy defects in Glanzmann's thrombasthenia patients.
• This strategy may reduce the need for blood transfusions and shorten hospitalizations, potentially offsetting costs.
