Study on the application value of 4K and 3D endoscopic system in benign thyroid disease surgery through transthoracic and breast approach

ObjectiveTo investigate the application value of 4K and 3D endoscopic system in benign thyroid disease surgery through transthoracic and breast approach.

MethodsFifty patients with benign thyroid disease were divided into the 4K group(n=25) and 3D group(n=25) according to the different endoscopic systems. The clinical indicators of two groups were collected and compared, and the subjective feelings of surgeons were investigated by questionnaire.

ResultsThere was no statistical significance in the operation time between the 4K group and 3D group(P>0.05). The building space time in 4K group was longer than that in 3D group(P < 0.01), and the difference of the time of gland resection was not statistically significant between two group(P>0.05). The differences of the intraoperative blood loss, postoperative drainage volume, drainage time, postoperative hospital stay and incidence of complications between two group were not statistically significant(P>0.05). The subjective perception questionnaire survey of surgeons showed that the visual fatigue, vertigo and color resolution in 4K group were higher than those in 3D group(P < 0.05). The spatial orientation and depth resolution in 3D group were higher than those in 4K group(P < 0.05). There was no statistical significance in the sense of operation between two groups(P>0.05).

ConclusionsCompared with the 3D endoscopic system, the 4K endoscopic system is safe and feasible in the application of benign thyroid disease surgery, and the 4K endoscopic system can provide better resolution and visual acuity, and reduce the visual fatigue. Compared with the 4K endoscopic system, the 3D endosscopic system can shorten the time of the building space during the operation, and provide a better sense of spatial orientation and depth.
