Purpose To evaluate the feasibility and effectiveness of the LigaSure device in closing divisions of the small bowel in an ex vivo porcine model. Methods Two types of closure were performed: stumps created by ‘‘muco-mucosa’’ fusion and stumps created by ‘‘sero-serosa’’ fusion. For each type of closure, different power levels of the LigaSure system were tested in com-bination with different numbers of applications and then compared with the Stapler group. Results With both types of intestinal closure, the highest value of burst pressure was obtained with the application of a power level of three bars and one frequency application. The high burst pressure of the muco-mucosa stump group was significantly lower than that of the Stapler group (41.8 ±5.9 vs. 75.8±5.9, respectively, p\0.01). No differences were found between the high burst pressure of the sero-serosa stump group and the Stapler group (74.1 ±5.5 vs. 75.8±5.9, respectively,p=0.2). Conclusions Our preliminary results showed that the LigaSure is an efficient tool for closing the intestines when sero-serosa stumps are created. The second step of our work will be to evaluate the feasibility of this tool in cre-ating intestinal anastomose

Abstract

Purpose To evaluate the feasibility and effectiveness of the LigaSure device in closing divisions of the small bowel in an ex vivo porcine model. Methods Two types of closure were performed: stumps created by ‘‘muco-mucosa’’ fusion and stumps created by ‘‘sero-serosa’’ fusion. For each type of closure, different power levels of the LigaSure system were tested in com-bination with different numbers of applications and then compared with the Stapler group. Results With both types of intestinal closure, the highest value of burst pressure was obtained with the application of a power level of three bars and one frequency application. The high burst pressure of the muco-mucosa stump group was significantly lower than that of the Stapler group (41.8 ±5.9 vs. 75.8±5.9, respectively, p\0.01). No differences were found between the high burst pressure of the sero-serosa stump group and the Stapler group (74.1 ±5.5 vs. 75.8±5.9, respectively,p=0.2). Conclusions Our preliminary results showed that the LigaSure is an efficient tool for closing the intestines when sero-serosa stumps are created. The second step of our work will be to evaluate the feasibility of this tool in cre-ating intestinal anastomose
