ObjectiveTo determine postoperative pain of the robotic technique for the patients with lobectomy. MethodsWe retrospectively analyzed the clinical data of 120 patients with lobectomy between October 2014 and May 2015 in our hospital. The patients are divided into two groups:a robotic group, including 40 patients with 16 males and 24 females at age of 59.7±7.2 years, undergoing robotic lobectomy, and a video-assisted thoraciscopic surgery (VATS) lobectomy group (a VATS group) including 80 patients with 29 males and 51 females at age of 61.2±8.9 years, undergoing VATS lobectomy. We used the numerical rating scale (NRS) and verbal rating scale (VRS) to assess the pain level on the first day, the 7th day and the 30th day after the surgery. The pain level of the two groups was compared. ResultsThe patients in the two groups both felt pain. There were no statistical differences in the scores of VRS and NRS on the first day, the 7th day and the 30th day after the surgery between the two group (P>0.05). The pain score of the patients in the two groups decreased with no statistical difference from the first day to the 30th day after the surgery (P>0.05). ConclusionThe patients with robotic lobectomy have similar pain level after surgery compared with the patients with VATS lobectomy.
