Abstract:

Objective  The purpose of this study is to compare the overall effects of surgical trauma and surgical results resulting from PELD and OD. Methods The patients were randomly allocated into two groups, the PELD and OD groups. Each group contained 10 patients. Blood loss, hospital stay, and skin incision size will be recorded in these two groups. In this study, a quantitative comparison will be performed through analysis of  patient's systemic cytokines, CPK and CRP response. An enzyme-linked immunosorbent assay (ELISA) was used for serum levels of Interleukin-1beta(IL-1), Interleukin-6 (IL-6), and Interleukin-8 (IL-8), Interleukin- 10(IL-10) and were measured before surgery and at 1,6,12 ,24 and 48 hours after surgery. Serum C-reactive protein (CRP) and creatine phosphokinase (CPK) were measured at the same time interval. Results The overall results showed PELD group had less blood loss ( P<0.01), less hospital stay(P<0.01), less skin incision size(P<0.01) than OD group. Using the modified MacNab criteria, the clinical outcomes were 90% in PELD and OD group at the  postoperative 6-month follow up. CRP、 CPK、IL-6 level showed significant difference at 24 hours and 48 hours between the two groups (P<0.01). The systemic IL-6, CRP and CPK were significantly less following PELD than OD. Conclusion PELD offers a similar short-term clinical outcome,with smaller incision,less tissue trauma and quicker recovery than OD.
