*, record pain score at time intervals different from other studies; ¤, subxiphoid approach. Pain scores are demonstrated as video-assisted thoracoscopic surgeries (VAS) from 0–10 if not mentioned otherwise. The columns are shaded grey to indicate significant differences between uni- and multi portal VATS, and P value is shown if provided. Thirteen of the 14 studies comparing postoperative pain show that uniportal VATS has at least one parameter superior to conventional VATS, except for McElnay’s study where there are no differences. POD, postoperative day; VAS, visual analog scale.
