Facilitating endorobotic submucosal dissection ( <scp>ERSD</scp> ) in transanal single‐port surgery: A comparative analysis of two ports—A video vignette

Transanal single-port surgery has emerged as a valuable technique for resecting challenging rectal lesions, offering an alternative to traditional endoscopic procedures [1, 2]. This video vignette demonstrates the effectiveness and technical application of this method, specifically showcasing the advantages of different access ports in endorobotic submucosal dissection (ERSD) (Video 1). We present a comparative analysis of two key transanal access ports for endorobotic rectal lesion resection: the da Vinci SP Access Port, commonly referred to as the ‘Bubble Port’, and the GelPOINT platform. This comparison highlights the da Vinci SP Access Port (‘Bubble Port’) with its ‘floating-docking’ technique and its role in overcoming the inherent spatial limitations of transanal surgery in the distal rectum. As demonstrated in Video 1, this method provides crucial depth and manoeuvrability for robotic instrumentation where limited space can otherwise restrict movement. For more proximal rectal lesions, away from the anal verge, this advantage is less critical, as a GelPOINT is usually sufficient. The vignette also illustrates the application of the GelPOINT platform for similar resections in different rectal locations. This presentation underscores how tailoring the access port to lesion characteristics and location can significantly enhance procedural ease and precision, ultimately improving outcomes in transanal rectal lesion resections.

Ethical approval was not taken for this video vignette as it involves only two patients and focuses on the technical demonstration of surgical methods. According to our institutional policy, formal ethics committee approval is waived for video vignettes involving two cases that are fully anonymized. Specific case details are provided in adherence to ethical guidelines to ensure patient privacy and confidentiality; no patient-identifiable information is included in the manuscript or the accompanying video. Human subjects were involved in the video vignette. Individual informed consent was not obtained due to the retrospective nature and complete anonymization of the video vignette. The data presented in this manuscript are a comparative analysis of two ports illustrated through two distinct case studies (video vignettes). There is no external dataset to be shared, as the analyses are derived directly from the detailed descriptions, visual evidence of these two clinical cases, all of which are included within the published manuscript itself. Specific case details are provided in adherence to ethical guidelines to ensure patient privacy and confidentiality are maintained.
