Abstract

Background

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.

Methods

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.

Results

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.

Conclusions

SP robotic transanal surgery allows flexible vision and meticulous procedures in narrow spaces; therefore, this method has greater feasibility and oncologic safety.

单端口机器人经肛门微创直肠肿瘤手术（SP-rTAMIS）的临床可行性和技术方面。

背景：单端口机器人平台提供关节和360°相机旋转在狭窄的骨盆空间肛肠肿瘤切除。本研究评估了SP机器人经肛门手术的临床有效性和结果。方法：采用SP机器人平台对9例经肛门切除术患者进行分析。使用GelPOINT路径经肛门通道和充气稳定袋来维持直肠膨胀。结果：所有患者均行全层切除，无术中并发症。距肛缘平均距离6.41 cm。由于360°旋转，无论肿瘤的方向如何，均采用俯卧位。平均手术时间66.1 min，平均对接时间8.7 min，仅对接1次。所有肿瘤切除边缘均为阴性，随访期间未见复发。结论：SP机器人经肛门手术可以在狭窄的空间内实现灵活的视觉和细致的手术；因此，该方法具有较大的可行性和肿瘤学安全性。

期刊介绍： The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
