Abstract:
Objective To explore the learning curve of endoscopic mesothyroid excision via gasless axillary approach.Methods Clinical data of 44 patients who underwent endoscopic mesothyroid excision via gasless axillary approach between May 2020 and December 2022 by the same surgical team were retrospectively analyzed.Taking operation time as index,the learning curve of the operation was studied with the cumulative sum method(CUSUM).The cut-off value of the learning curve was regarded as the dividing line of different stages.The general data,operation time,intraoperative blood loss,hospital stay,number of lymph node dissection,and postoperative complications were compared between the different phases of the learning curve.Results The operations were successfully completed in all the 44 patients without conversion to open surgery.The cumulative sum fitting curve reached the top at the 21st case,which was used as the boundary to divide the learning curve into learning improvement stage and mature stable period.There was no statistically significant difference between the two stages in general data(P>0.05).The operation time in the learning improvement stage was significantly longer than in the mature stable period[(124.5±9.9)min vs.(82.0±8.8)min,t =15.166,P =0.000].The incidence of postoperative sternocleidomastoid muscle swelling and stiffness in patients in the learning improvement stage was higher than that in the mature stable period,but the difference was not statistically significant[6 cases(28.6%)vs.1 case(4.3%),χ2 =3.174,P =0.075].There was no significant difference between the two groups in terms of intraoperative bleeding,hospital stay,number of lymph node dissection,and other postoperative complications(all P>0.05).Conclusion To proficiently master the endoscopic mesothyroid excision via the gasless axillary approach,21 cases need to be completed.
