For a small intestinal anastomosis in surgery, which suture pattern is typically used?

• A. Simple interrupted
• B. Continuous running
• C. Mattress
• D. Ford interlocking

Answer: (A)

The key idea is to achieve precise edge alignment and maintain the lumen while preserving tissue viability. Simple interrupted sutures let you place and tie each bite individually, so the mucosal edges meet exactly and you can adjust tension at each point. This control is especially important in the small intestine, where edema and fragile tissue are common; if one stitch loosens or tissue swells, the rest of the line remains intact and the overall patency isn’t compromised. A continuous running pattern links all bites into one line, so a single issue can affect the entire closure and may increase the risk of luminal narrowing. Other patterns like mattress or interlocking stitches impose more tissue tension and can contribute to ischemia or stenosis and are less forgiving when adjustments are needed. For these reasons, simple interrupted sutures are typically used for small intestinal anastomosis.
