Abstract:

【Abstract】〓Objective〓To investigate the feasibility of gasless endoscope-assisted neck dissection via the anterior chest wall and the ear-behind neck incision (the improved dual parallel incision) in cN0 papillary thyroid carcinoma (PCT). Methods〓Forth-five patients with cN0 PCT underwent endoscopic neck dissection, including 11 patients with pathological lymph node metastasis at level VI (endoscopic group). Meanwhile, another 11 patients with cN0 PCT underwent traditional neck dissection (traditional group). Operation time, estimated intraoperative blood loss, lymph node number at level II~IV and their metastasis number,.complications were compared between the two groups. Results〓Operation time was no difference (t=1.227, P=0.233) between endoscopic group (218.16±31.54 min) and traditional group (202.35±28.81 min). There was no difference (t=1.922, P=0.068) in intraoperative blood loss between endoscopic group (52.42±13.25 mL) and traditional group (64.27±15.57 mL). Lymph node number at level II-IV and their metastasis number were also no difference.(t=0.390,P=0.700 and t=1.913, P=0.070) in endoscopic group (15.37±4.61 and 2.82±0.34) and traditional group (16.19±5.23 and 3.15±0.46). There were one case of transient hoarseness in endoscopic group and one of lymphorrhagia in traditional group, and one of transient hypocalcemia in both groups. No difference was observed in complication occurrence between two groups..(χ2 =2.000, P=0.367). Conculsion Endoscopic neck dissection in cN0 papillary thyroid carcinoma is safe and feasible.
