Comparison of surgical outcomes between robotic & laparoscopic single-site myomectomies

Abstract

Objective: To compare surgical outcomes of robotic single-site myomectomy (RSSM) and laparoscopic single-site myomectomy (LSSM). Methods: The medical records of 105 consecutive women who had undergone RSSM and 183 consecutive women on whom LSSM had been performed were retrospectively reviewed. The clinical characteristics and surgical outcomes between these groups were compared. Results: Age at the time of surgery was younger among RSSM women than for LSSM patients (36.76.3 vs. 38.76.7 years, P=0.010). In the RSSM group, whereas there were more unmarried (48.6% vs. 34.4%, P=0.018) and nulliparous (73.3% vs. 59.6%, P=0.019) women, there were fewer women who had undergone previous abdominal surgery (18.1% vs. 32.8%, P=0.007) and peritoneal adhesion (7.6% vs. 23.0%, P=0.001). Total operation time was longer in the RSSM group than in the LSSM group (145.853.7 vs. 117.544.8 minutes, P<0.001). Estimated blood loss (210.1162.2 vs. 161.4158.7 mL, P=0.013) was much higher in the RSSM group than in the LSSM group. Hemoglobin decrement (1.41.1 vs. 1.61.1 g/dL, P=0.120) and blood transfusion performance (1.0% vs. 1.1%, P=0.910) were similar between the two groups. The duration of hospital stay (4.70.9 vs. 5.41.0 days, P<0.001) was shorter in the RSSM group. No one in the RSSM group had any operation-related complications. However, one ileus and one wound dehiscence were diagnosed in the LSSM group (P=0.309). Conclusion: Although the hospital stay might be shorter, RSSM showed longer operation time and higher estimated blood loss.
