Purpose: To compare perioperative outcomes between robotic single-site surgical technique and conventional laparoendoscopic single-site surgical technique.
Methods: This was a retrospective cohort study involving 67 patients who received robotic single-site surgery or laparoendoscopic single-site surgery for the treatment of stage IB1 cervical squamous carcinoma. The robotic single-site radical hysterectomy technique combined with pelvic lymph node dissections were performed in 32 patients while the laparoendoscopic single-site radical hysterectomy technique combined with pelvic lymph node dissections were performed in 35 patients.
Results: The enrolled patients had been diagnosed with stage IB1 cervical squamous carcinoma. The perioperative outcomes were mean age (51.63± 8.32 years in the lymph node dissection (RSS group) and 53.14± 8.14 years in the lymph node dissection (LESS group), p=0.453); BMIs (23.76± 2.72 in the RSS group and 23.46± 2.28 in the LESS group, p=0.629); shorter operative times (223.56± 15.43 min in the RSS group and 248.61± 20.89 min in the LESS group, p< 0.01) and less estimated blood loss (217.25± 16.77 mL in the RSS group and 294.74± 24.00 mL in the LESS group, p< 0.01). None of the study participants exhibited postoperative pain. There were no statistically significant differences in the length of hospital stay (p=0.865), perioperative complications (p=0.602), duration of closure and removal of catheter (p=0.518) as well as in pathological diagnoses between the two groups.
Conclusion: Robotic single-site surgery can be used in the treatment of early stage cervical cancer as it exhibits acceptable operative times and perioperative outcomes. This surgical technique is feasible and safe.
