Résumé
Off-label use of radiofrequency vessel sealing devices for intestinal thermofusion has been reported as an alternate approach for closing the small and large intestines. The study aimed to evaluate if reinforcing the thermofusion line with a modified N-butyl-2-CyanoAcrylate and methacryloxysulpholane produced improved burst pressure values in ex vivo swine jejunal loops. A suture-less full-thickness jejunal biopsy was performed with different radiofrequency vessel-sealing devices (Ligasure 5 mm: RFVS-1; Atlast 10 mm: RFVS-2; Cayman Maryland: RFVS-3), and reinforcement with modified cyanoacrylate Glubran-2 (G2) at the thermofusion defect was applied. Burst pressure(BP) values were compared with a control group, wherein a cold blade was utilized to obtain the biopsy, followed by the closing of the jejunum with seven Gambee sutures. Seventy (n = 70) jejunal loop samples were distributed into the experimental groups.The RFVS-1 and -2 groups exhibited BP values similar to those of the suture group. The RFVS-3 group showed significantly lower BP values (P < 0.05) than the suture group. Conversely, in the groups wherein G2 was applied, all BP values were comparable to those of the suture group. BP test in the RFVS-3G2 group showed significantly (P < 0.05) higher values in the group using the same instrument without the glue (RFVS-3). G2 has been shown to improve the BP on the defects created by instruments that are not completely efficient in intestinal thermofusion and sealing. This experimental model showed that the performance of full-thickness biopsies with RFVS devices and reinforcement with G2 provide feasible and promising results.

BACKGROUND
Off-label use of radiofrequency vessel sealing devices for intestinal thermofusion has been reported as an alternate approach for closing the small and large intestines. The study aimed to evaluate if reinforcing the thermofusion line with a modified N-butyl-2-CyanoAcrylate and methacryloxysulpholane produced improved burst pressure values in ex vivo swine jejunal loops.
MATERIALS AND METHOD
A suture-less full-thickness jejunal biopsy was performed with different radiofrequency vessel-sealing devices (Ligasure 5 mm: RFVS-1; Atlast 10 mm: RFVS-2; Cayman Maryland: RFVS-3), and reinforcement with modified cyanoacrylate Glubran-2 (G2) at the thermofusion defect was applied. Burst pressure(BP) values were compared with a control group, wherein a cold blade was utilized to obtain the biopsy, followed by the closing of the jejunum with seven Gambee sutures.
RESULTS
Seventy (n = 70) jejunal loop samples were distributed into the experimental groups.The RFVS-1 and -2 groups exhibited BP values similar to those of the suture group. The RFVS-3 group showed significantly lower BP values (P < 0.05) than the suture group. Conversely, in the groups wherein G2 was applied, all BP values were comparable to those of the suture group. BP test in the RFVS-3G2 group showed significantly (P < 0.05) higher values in the group using the same instrument without the glue (RFVS-3).
CONCLUSIONS
G2 has been shown to improve the BP on the defects created by instruments that are not completely efficient in intestinal thermofusion and sealing. This experimental model showed that the performance of full-thickness biopsies with RFVS devices and reinforcement with G2 provide feasible and promising results.
