[Influencing factors on surgical duration of ovarian cystectomy by single-port access]

OBJECTIVES: To evaluate the factors influencing the operative duration of ovarian cystectomy by single-port access (SPA). MATERIALS AND METHODS: Observational monocentric study from June 2010 to September 2012. Inclusive patients were patients with an indication of ovarian cystectomy may be done by laparoscopy. The procedures were performed by the SPA system LESS®. Factors evaluated were BMI of the patient, histological nature and size of the cyst. RESULTS: We performed 54 cystectomy in 49 patients. SPA surgery was successfully completed in 53 patients. The median operative time was statistically longer for endometriotic cysts than dermoid cysts or serous-mucinous cysts (P=0.003). Cases exceeding 60minutes were significantly higher in the endometriosis group (P=0.005). There wasn't correlation found between the BMI of the patient and operative time (P=0.5). The operating time wasn't increased according to the size of the cyst (P=0.9). CONCLUSION: Endometriotic cysts nature appears to be the only limiting factor of cystectomy by SPA. Further studies are needed to evaluate the factors that may limit the SPA actions.
