OBJECTIVES: This study compares the uniportal with the 3-portal video-assisted thoracic surgery (VATS) by examining the data collected in the Italian VATS Group Database. The primary end point was early postoperative pain; secondary end points were intraoperative and postoperative complications, surgical time, number of dissected lymph nodes and length of stay.METHODS: This was an observational, retrospective, cohort, multicentre study on data collected by 49 Italian thoracic units. Inclusion criteria were clinical stage I-II non-small-cell lung cancer, uniportal or 3-portal VATS lobectomy and R0 resection. Exclusion criteria were cT3 disease, previous thoracic malignancy, induction therapy, significant comorbidities and conversion to other techniques. The pain parameter was dichotomized: the numeric rating scale <= 3 described mild pain, whereas the numeric rating scale score >3 described moderate/severe pain. The propensity score-adjusted generalized estimating equation was used to compare the uniportal with 3-portal lobectomy.RESULTS: Among 4338 patients enrolled from January 2014 to July 2017, 1980 met the inclusion criteria; 1808 patients underwent 3-portal lobectomy and 172 uniportal surgery. The adjusted generalized estimating equation regression model using the propensity score showed that over time pain decreased in both groups (P<0.001). There was a statistical difference on the second and third postoperative days; odds ratio (OR) 2.28 [95% confidence interval (CI) 1.62-3.21; P<0.001] and OR 2.58 (95% CI 1.74-3.83; P<0.001), respectively. The uniportal-VATS group had higher operative time (P<0.001), shorter chest drain permanence (P<0.001) and shorter length of stay (P<0.001).CONCLUSIONS: Data from the Italian VATS Group Database showed that in clinical practice uniportal lobectomy seems to entail a higher risk of moderate/severe pain on second and third postoperative days.
