Situation

Inserting transanally a circular stapler, e.g. for resection with an anastomosis, there are some risks of injuries: 

• Sphincter lesion
• Internal sphincter rupture
• Collision with the mucous membrane folds (mucosa)
• Risk of perforation

These risks stem mainly from the angular edge of the stapler. 

Eventual consequences

• Up to 36% of patients suffer temporary  of anal incontinence 
• 18% of patients suffer from a  sphincter  injury 
• Anal incontinence for liquid stool

Situation

Stool residuals are in the bowel and often contaminate the stapler head / stapler seam
