BACKGROUND: Although many mechanical devices are being developed for functional end-to-end anastomosis (FETEA), the best choice remains to be determined. The mechanical strength of each device is an important factor associated with anastomotic leakage. In turn, anastomotic patency is related to postoperative stenosis. This study examined the bursting pressure and circumference of several FETEAs. METHODS: Young domestic pigs were used in this study. In experiment 1, a 10-cm segment of intestine was transected using an EndoGIA 60 blue, EndoGIA 60 green, or GIA 60 blue stapler, and the bursting pressure of each instrument's mechanical staple line was examined. In experiment 2, after FETEA had been created with EndoGIA 60 blue, the bursting sites were examined, and the bursting pressures of buttressed and nonbuttressed FETEA were measured and compared. In experiment 3, the circumference of FETEA was compared between the closed technique and reinforcement. RESULTS: The bursting pressure of EndoGIA 60 blue was significantly higher than that of the other devices. When an anastomotic crotch was buttressed, the bursting pressure (44 +/- 13 mmHg) was significantly increased over that of the nonbuttressed FETEA (27.5 +/- 5.8 mmHg; p < 0.05). The circumference of FETEA using the wide technique (92.7 +/- 2.3 mm) was larger than that using the offset technique (55.7 +/- 5.8 mm). CONCLUSIONS: The bursting pressure of the mechanical staple line using the EndoGIA 60 stapler was the strongest. Functional end-to-end anastomosis was stronger when created with buttress of an anastomotic crotch, and larger circumferences were created with the wide technique.
