Single port robotic platform offers articulation and 360° camera rotation for anorectal tumour excision in a narrow pelvic space. This study assesses the clinical usefulness and outcomes of SP robotic transanal surgery.
Nine patients who underwent transanal excision using the SP robotic platform were included. A GelPOINT path Transanal Access channel with insufflation stabilisation bag was used to maintain rectal inflation.
All patients underwent full-thickness excision without intraoperative complications. The mean distance from anal verge was 6.41 cm. Prone position was used regardless of the direction of the tumour due to the 360° rotation. The mean operative time was 66.1 min. The mean docking time was 8.7 min with only one docking. All oncologic resection margins were negative, and recurrence was not observed during follow-up.
SP robotic transanal surgery allows flexible vision and meticulous procedures in narrow spaces; therefore, this method has greater feasibility and oncologic safety.
单孔机器人平台为在狭窄盆腔空间内进行的肛肠肿瘤切除提供了关节活动和360°摄像头旋转功能。本研究评估了单孔机器人经肛门手术的临床实用性和结果。
纳入9例使用单孔机器人平台进行经肛门切除的患者。使用带有充气稳定袋的GelPOINT path经肛门入路通道来维持直肠充气。
所有患者均接受了全层切除，术中无并发症。距肛缘的平均距离为6.41厘米。由于可360°旋转，无论肿瘤方向如何均采用俯卧位。平均手术时间为66.1分钟。仅进行一次对接，平均对接时间为8.7分钟。所有肿瘤切除切缘均为阴性，随访期间未观察到复发。
单孔机器人经肛门手术在狭窄空间内具有灵活的视野和精细的操作；因此，该方法具有更高的可行性和肿瘤学安全性。
