Video-assisted thoracoscopic surgery lobectomy using "the caudal approach": results and evolution

Totally thoracoscopic versus standard VATS lobectomies: perioperative differences

BACKGROUND

Minimally invasive surgery is considered the gold standard approach for early stage lung cancer. Techniques range from a standard three-port approach to uniportal lobectomies, with no technique emerging as superior thus far. We retrospectively compared the pain outcomes of a standard approach using a utility incision with a totally thoracoscopic technique.

METHODS

Between January 2015 and December 2019, 168 patients received a VATS lobectomy in our centers. Two groups were created, Group A (82 patients, totally thoracoscopic approach) and Group B (86 patients, standard approach with utility incision). Perioperative outcomes, such as operative time, complications, length of stay, perioperative and chronic pain using visual analog scale (VAS), and rescue doses of painkillers were examined. A one-way analysis of covariance (ANCOVA) was conducted to investigate the impact of surgical time and days of drainage on VAS score.

RESULTS

Pain was less on postoperative day (POD) 1 and 2 (p = 0.025 and p = 0.020, respectively) in Group A. No differences were found in the baseline and perioperative characteristics of the two groups, in the mean VAS score at 1 month (p = 0.429), 1 year (p = 0.561), doses of NSAIDs (p = 0.609), and chronic pain (3vs7 patients, p = 0.220). The ANCOVA test showed no significant effect of surgical time and days of drainage on VAS score (p > 0.05).

CONCLUSIONS

In our experience, a totally thoracoscopic approach may improve acute postoperative pain without compromising the oncological results of the procedure and the safety of the patients.
