Abstract

Abstract: This article discussed the value of preoperative color Doppler ultrasound-guided injection of nano-carbon suspension to guide laparoscopic surgery in patients with papillary thyroid carcinoma (PTC). Ninety-eight patients with PTC were selected as the research objects, according whether the patients adopted the nano-carbon tracking technology with ultrasound-guided, the patients were divided into the tracer group with 58 cases and the traditional group with 40 cases. The patients in the tracer group were injected with nano-carbon suspension under the guidance of color Doppler ultrasound before operation, and the surgeons were instructed to perform lymph node dissection in the central area of the neck. The traditional group were performed lymph node dissection in the central area of the neck by traditional surgical methods. The calcium levels in blood were analyzed by biochemical assays and the serum PTH level was detected by linked immunosorbent assay. The operation time and intraoperative blood loss in the tracer group were significantly lower than those in the traditional group (P<0.05). The number of dissected central lymph nodes and the number of positive central lymph nodes in the tracer group were higher than those in the traditional group (P<0.05). At 24 hour and 72 hour after the operation, the serum PTH and blood calcium levels in the two groups were lower than 535those in the same group before the operation (P<0.05). Compared with the tracer group, the serum PTH and blood calcium levels in the traditional group were significantly lower (P<0.05). The postoperative complication rate in the tracer group was lower than that in the traditional group (P<0.05). Color Doppler-guided injection of nano-carbon suspension lymph node tracing to guide endoscopic central lymph node dissection in patients with PTC has higher practical value, which is benefit to shorten the operation time, reduce the difficulty of operation, improve the efficiency of lymph node dissection, and reduce parathyroid glands incidence of collateral injuries and surgical complications.
