Comparison of the performance of the Gea extracorporeal knot with the Roeder extracorporeal knot and the classical knot.
BACKGROUND
Laparoscopy is useful to treat surgical diseases, yet tying sutures in the cavity is a challenge. A knot to secure tissue approximation, which would be hand-made, secure, simple, easy, quick, reliable, and extracorporeal without extra mechanical devices, was developed and named the Gea knot.


METHODS
A comparative study of the Gea knot, the Roeder knot, and the classical surgical knot, as the gold standard, using polypropylene, silk, catgut, polyglycolic acid, and Polyglactin 910, all of them of 1-0 caliber, was performed in pigs. Measurements were time to perform, slippage, and breaking point which was measured with a manual digital tensiometer.


RESULTS
The Gea knot was significantly faster statistically to perform than the Roeder knot and more resistant against rupture and slippage. The slippage rate was significantly lower statistically in the Gea knot than in the Roeder knot when Polyglactin 910 and polypropylene were used.


CONCLUSIONS
The Gea knot is a good alternative for laparoscopic procedures.
