What are the recommended staple heights for vascular, GI tract, and distal stomach or thickened GI tract respectively?

• A. vascular 3-3.5 mm; GI 2-2.5 mm; distal 4-4.5 mm
• B. vascular 1-1.5 mm; GI 2-2.5 mm; distal 3-3.5 mm
• C. vascular 3-3.5 mm; GI 4-4.5 mm; distal 5-5.5 mm
• D. vascular 2-2.5 mm; GI 3-3.5 mm; distal 4-4.5 mm

Answer: (D)

Selecting staple height is about matching the staple to the thickness of the tissue you’re joining. Vascular tissue is thin and delicate, so you use the smallest staple height to avoid crushing the vessel while still achieving hemostasis. A height of 2-2.5 mm fits this, providing enough compression without excessive tissue damage. The GI tract wall sits thicker than vessels but thinner than a thickened area, so a moderate height of 3-3.5 mm gives reliable closure without over-compression. For the distal stomach or thickened GI tissue, the tissue is the thickest, requiring a larger staple height of 4-4.5 mm to ensure proper invagination and a secure seal. This progression—2-2.5 mm for vascular, 3-3.5 mm for GI, and 4-4.5 mm for distal stomach/thickened tissue—best matches tissue thickness and achieves safe, effective stapling.
