Abstracts

Background: Staplers make it possible to create a gastrointestinal anastomosis quickly, easily, and securely. Staplers have undergone several improvements. We herein evaluate the effect of a new stapler with unique surface gripping technology that provides a superior tissue grip without trauma during firing.

Methods: Porcine small bowel was used. The stapling devices compared were the ECHELON FLEXTM with White (E) and GST System White (G). The number of total malformed staples, severely malformed staples, staples malformed to the cutting side, and the absolute value of the degree of malformation were evaluated.

Results: The number of malformed staples and the absolute value of the degree of malformation were significantly lower in group G. The number of occurrences of total malformations <0 was greater in group G. Comparing the inner, middle, and outer staple rows, the number of occurrences of malformations were lower on the outer row in group E. Comparing the front, middle, and back parts malformation was lower in the front.

Conclusions: We found that a new stapler is superior to a standard stapler with regard to a reliable “B” shape formation of staples. Future directions include studying the correlation between staple malformation and the strength of the suture line.
