Can LigaSure seal and divide the small bowel?

Abstract:

BACKGROUND:The LigaSure system (Valleylab, Boulder, CO) seals vessels by reforming collagen and elastin in vessel walls. We studied the feasibility and effectiveness of LigaSure in dividing porcine small bowel. METHODS:Twelve porcine small bowel portions were randomized to division with either endoscopic linear stapler or LigaSure system and the burst pressure of the sealed ends were measured. RESULTS:Segments sealed with staples (6), LigaSure Atlas (Valleylab) (7), LigaSure Xtd (Valleylab) (4), and double-sealed with LigaSure Atlas (Valleylab) (4) were compared. Burst pressure for stapled segments was 131 (standard deviation [SD] 19) mm Hg; failure occurred in the bowel wall. Burst pressures for the 3 groups of Ligasure segments were 27 (SD 5), 20 (SD 6), and 11 (SD 13) mm Hg, respectively, with no statistically significant difference among them; failure occurred at the sealed end. Burst pressure for stapled segments was significantly higher than that of Ligasure segments (P < .001). CONCLUSION:LigaSure does not safely seal small bowel.
