[Experimental study on the resistance to intraluminal pressure between handsewn and stapled anastomosis. In vitro experimental study].

Intoduction and aim: The aim of the study was to compare the resistance to pressure of stapled and manually handsewn intestinal suture lines on in vitro pig intestine model.

METHOD: We performed different types of stapled and manual sutures and the pressure level was measured using a differential pressure manometer.

RESULTS: Although the hand-sewn end-to-end suture turned out to be the most resistant to pressure, statistical analysis revealed no significant differences compared to stapled suture (p = 0.49). In stump closure techniques, we observed a statistically high significance in resistance to pressure in the favour of manual stump closure (p = 0.004).Regarding side-to-side sutures we did not find any statistically significant differences in resistance to pressure between the techniques (p = 0.06).

CONCLUSION: We can conclude that regarding the stump closure, the most resistant to pressure is the hand-sewn procedure, but in the other types of anastomosis, no significant differences was found between the stapled and hand-sewn techniques. Orv Hetil. 2017; 158(42): 1674-1680.
