Comparison of postoperative pain in robotic and laparoscopic myomectomy: a retrospective cohort study.

ABSTRACT

Gynecologic surgery with minimally invasive method using robotic or laparoscopic techniques has gained popularity for reducing perioperative discomfort and length of hospital stay. However, the debate over postoperative pain superiority between traditional laparoscopy and robotic surgery persist. This study compared the postoperative pain of patients within 24 h of robotic (RM) and laparoscopic myomectomy (LM). This retrospective cohort study included 24 and 53 patients who underwent RM and LM, respectively, between January 2019 and July 2023. The primary outcomes were the postoperative pain levels of patients within 24 h and the use and dosage of postoperative analgesia. Additional perioperative analgesia, including long-acting non-steroidal anti-inflammatory drugs (Dynastat) and abdominal nerve block, was also recorded. The secondary outcomes were blood loss and hospitalization duration. The patient characteristics were similar between the groups. Factors that could potentially increase pain, such as the number of ports (p < 0.0001), additional procedures (p = 0.0195), operative time (p < 0.0001), number of myomas (p = 0.0057), and the largest myoma size (p = 0.0086), were significantly higher in the RM group than in the LM group. However, there were no significantly different in the postoperative visual analog scale pain scores, use and dosage of ketorolac and opioid, and use of Dynastat and nerve block between the groups. Hospitalization duration and intraoperative blood loss were similar between the groups. RM and LM offer comparable postoperative pain outcomes, emphasizing the importance of patient-specific factors in decision-making regarding myomectomy techniques.
