Robotic 8-mm trocar fascial wounds: To close or not to close?

Abstract

The aim of this study was to investigate 8-mm robotic trocar site hernia (TSH) rate over the short and long term, providing aids to manage the related fascial wounds. A retrospective analysis of 320 patients undergoing robotic surgery was conducted. The primary outcome was 8-mm TSH rate with a minimum follow-up of 12months. The secondary outcome was the rate of haematomas and infections related to 8-mm wounds and their association with patient comorbidities and trocar position. One case of TSH was observed (0.31%). There were 15 cases of wound infection (4.68%) and 22 cases of wound haematoma (6.87%). Trocar related complications were significantly associated with patient comorbidities, not with trocar position. Our results do not justify the 8-mm fascial wound closure. Data concerning the association between trocar-related complications and patient comorbidities strengthen the need to implement the control of metabolic state and correct administration of perioperative therapy in high-risk patients.
