The aim of this study is to verify whether differences could be found
or not as concerns of the postoperative surgical stress between the co
nventional open herniorrhaphy and laparoscopic herniorrhaphy. We there
fore compared the immunological and inflammatory responses to open and
laparoscopic procedures in this study. The sex, age, weight, and heig
ht characteristics of group 1 (open surgery group) matched those of gr
oup 2 (laparoscopic surgery group), and no statistically significant d
ifferences were found between them. Nor were there any statistically s
ignificant differences in operating time or the postoperative hospital
ization. Blood samples were collected preoperatively [postoperative da
y (POD) 0], POD 1 and 5, and the following parameters were assessed: t
otal leukocyte (WBC) count, including neutrophil and lymphocyte subpop
ulations, HLA-DR(+)CD3(+), IL-6, C-reactive protein (CRP), serum album
in, and body temperature. No differences were detected between two gro
ups in leukocyte, neutrophil, or lymphocyte count, HLA-DR(+)CD3(+), IL
-6, albumin, or body temperature on any of the postoperative days. The
only statistically significant difference was a higher CRP value in t
he laparoscopy group than the open group only on POD 1 (p < 0.05). It
can be concluded that the laparoscopic approach appears to offer no ad
vantages over the open approach to herniorrhaphy from the standpoint o
f immunological and inflammatory responses.
