- Abstract
Introduction: Reduced invasiveness has a potential benefit of reduced postoperative pain however there is a relative paucity of prospective data to confirm this presumption. The analysis of this prospective study was to compare pain score results in patients who underwent minimally invasive video-assisted (MIVAT) versus minimally invasive open thyroidectomy (MIT) and in doing so further extrapolate the potential advantages of video-assisted thyroid surgery. Materials and methods: A total of 98 patients post minimally invasive thyroidectomy from January 1st to December 31st 2008 are the subject matter of this study. Pain scores (0-10) assigned by the patients shortly after the thyroidectomy and after 24 hours postoperative forms the basic outcome variable. For statistical comparison of the distributions of the pain scores between patients the Kolmogrov- Smirnov (KS) test was employed. Results: The comparison pain score distribution using the KS test for postoperative assessment yielded a Z-value of 2.84 (P < 0.001). The comparison pain score distribution at 24 hours yielded a Z-value of 1.48 (P < 0.05). These results imply the difference in distributions of pain scores among MIT and MIVAT group to be statistically significant. Conclusions: We concluded that video-assisted thyroidectomy appears to reduce the pain in patients shortly after the operation and 24 hours postoperative. The reduction is statistically significant. Male patients appear to report less pain compared to their female counter parts.
