Robot-assisted lobectomy versus completely portal robotic lobectomy: What is the difference?

摘要

BACKGROUND: This study aims to compare robot-assisted lobectomy versus completely portal robotic lobectomy. METHODS: Between January 2014 and December 2019, a total of 41 patients (10 males, 31 females; median age 62 years; range, 50 to 68 years) underwent robotic anatomical pulmonary resection in our institution were retrospectively analyzed. The patients were consecutively divided into two groups: the first 20 (48.8%) patients underwent pulmonary resection by robot-assisted lobectomy technique, while the next 21 (51.2%) patients underwent pulmonary resection by completely portal robotic lobectomy with four arms. Data including age, sex, diagnosis, surgery type and duration, rate of conversion to open surgery, and length of stay of the patients were recorded. The operation time, docking time, console time, and closure duration for each patient were also noted. RESULTS: There was no statistically significant difference in age, sex, comorbidities, complications, length of hospital stay, adequate lymph node staging, or tumor size and side between the two groups (p>0.05). However, the mean console and operation times were statistically significantly shorter in the patients receiving completely portal robotic lobectomy with four arms (p=0.001). CONCLUSION: The advantage of completely portal robotic lobectomy with four arms is relative, although it significantly shortens the operation time. Based on our experiences, this technique may be preferred in case of inadequate lung deflation, as carbon dioxide insufflation allows sufficient workspace for robotic lung resection.
