To observe the effect of non-inflatable transaxillary endoscopic thyroid surgery (PTMC) on perioperative indexes, lymph node dissection and postoperative recurrence.

Clinical data of 96 PTMC patients who received treatment from April 2019 to April 2021 were retrospectively analyzed and divided into two groups according to different operation methods: the endoscopic group (n=45 cases) underwent non-inflatable transaxillary approach endoscopic surgery, and the open group (n=51 cases) underwent open surgery. Analyze the data using SPSS 20.0. Perioperative indicators, pain scores and other measurement data were expressed as (), and independent sample t test was used. The statistical data of postoperative complications and recurrence rate were chi-square test. P < 0.05 was considered statistically significant.

The incision length and intraoperative blood loss in the endoscopic group were less than those in the open group (P < 0.05), and the operation time, hospital stay and postoperative drainage volume were more than those in the control group (P < 0.05). There was no significant difference in the number of lymph node dissection and the number of positive dissection between the two groups (P > 0.05). The VAS pain scores in the endoscopic group were lower than those in the open group at 1d and 2d after surgery (P < 0.05). The complication rate of endoscopic group was lower than that of open group 2 weeks after surgery (P < 0.05). 2 years after discharge, there was no significant difference in recurrence rate between the two groups (P > 0.05).

Compared with open surgery, non-inflatable transaxillary endoscopic thyroid surgery for PTMC can shorten incision length, relieve pain and bleeding, and reduce complications.
