Context:
LigaSure™ is considered safe in performing pancreaticoduodenectomy (PD). However, no data are available regarding the possible damage of tissues at the resection margins and the impact thereof on histologic margin assessment.
Objective:
This study compares the degree of histologic damage to the resection margins when using LigaSure™ (Group 1) or traditional ligature (Group 2).
Methods:
Both groups included 8 consecutive patients who underwent PD at Karolinska Institute in December 2013 (Group 1) or earlier (Group 2) by the same surgeon (M.D.C.). The quality of tissues at the circumferential margins was compared between both groups by scoring for three different kinds of damage: tissue fragmentation, hemorrhage, and cell damage.
Results:
The mean score for fragmentation was 1.3 (Group 1) versus 1.7 (Group 2; P=0.1). For hemorrhage the mean score was 0.8 (Group 1) versus 1.5 (Group 2; P=0.04). The mean score for cell damage was 1.4 (Group 1) compared to 1.2 (Group 2; P=0.1).
Conclusions:
LigaSure™ does not cause tissue damage that could affect histologic margin assessment in PD specimens.
