Effect of two short striae incision or traditional "L" shaped incision in neck dissection of differentiated thyroid carcinoma on serum trauma cytokines

Abstract

To compare the trauma of neck dissection on the human body between two-striae incision and traditional "L" shaped incision by serum trauma cytokines. Patients with differentiated thyroid carcinoma hospitized from December 2008 to July 2011 were divided into 2 groups according to their own will. The first group 26 patients) had two-striae incision and the second group 32 patients) had traditional "L" shaped incision. The serum level of interleukin(IL)-2, IL-6 and C-reactive protein (CRP) in all patients were examined 1 day before and 1, 3 and 5 days after the surgery. No statistical significance was found between the 2 groups, although level of IL-2 decreased 1 day after the surgery, but recovered to normal 3 days later. The level of IL-6 in both groups increased 1 day after the surgery, began to decrease 3 days after the surgery, and recovered to normal 5 days after the surgery. The level of CRP suggested statistical significance (P<0.05), which increased obviously 1, 3 and 5 days after the surgery. No statistical difference was found before or after the surgery between the 2 groups (P>0.05). After follow-up for 8-40 months, no local recurrence or lymph node metastasis was found. Compared with the traditional "L" shaped incision, two-striae incision in neck dissection does not increase the serum level of trauma cytokines and trauma to human body after the surgery. Two-striae incision is an ideal surgical approach to differentiated thyroid carcinoma.
