Effect and feasibility of uniportal thoracoscopic surgery in the treatment of early-stage lung cancer in a primary hospital

BACKGROUND: Thoracoscopic radical lobectomy is a routine procedure for radical surgery of lung cancer. Meanwhile, thoracoscopic surgery has been gradually transformed from assisted small incision and multiport thoracoscopic radical surgery to uniportal thoracoscopic surgery for treatment of early-stage lung cancers. However, there are still controversies regarding the efficacy and feasibility of 2 surgical methods. The purpose of this study is to investigate the effect and feasibility of uniportal thoracoscopic surgery for treatment of early-stage lung cancer in a primary hospital. METHODS: Clinical data of 142 patients with early-stage lung cancer were retrospectively chosen in the period from September 2019 to March 2021 in our hospital and divided into 2 groups: a control group (66 patients) with 3-port thoracoscopic radical surgery and an experimental group (76 patients) with uniportal thoracoscopic radical surgery. The baseline clinical data, perioperative clinical data, and lymph node dissection of 2 groups were compared. RESULTS: There was no significant difference in baseline general clinical data between 2 groups (P>0.05), and no significant difference in the incidence of postoperative complications, conversion rate, or operation time between 2 groups (P>0.05). The intraoperative blood loss volume, postoperative chest drainage volume, postoperative hospitalization time, and postoperative catheter time of experimental group were significantly lower than those of control group (P<0.05). There was no significant difference in the total number of lymph node dissection stations and lymph node dissections, the number of N2 lymph node dissection stations, or N2 lymph node dissections between 2 groups (P>0.05). There was also no significant difference in the number of left and right lymph node dissection stations between 2 groups (P>0.05). CONCLUSIONS: Compared with 3-port thoracoscopic radical surgery, uniportal thoracoscopic radical surgery in the treatment of patients with early-stage lung cancer provides the same effect of lymph node dissection and has advantages in reducing surgical trauma and accelerating postoperative rehabilitation, popularizing for use in primary hospitals.
