Advancing Mid-Rectal Cancer Surgery: Unveiling the Potential of Natural Orifice Specimen Extraction Surgery (NOSES) in Comparison to Conventional Laparoscopic-Assisted Resection (CLAR)

<p><strong>Supplementary Material_1</strong><strong>:</strong>These supplementary videos offer a comprehensive visual guide to the NOSES surgical procedure, highlighting each significant step with precision and clarity.</p> <p><strong><em>Supplementary Video 1: Mobilization of the Descending and Sigmoid Colon.</em></strong></p> <p>This video illustrates the crucial first step in the NOSES surgical procedure, demonstrating the meticulous mobilization of the descending and sigmoid colon.</p> <p><strong><em>Supplementary Video 2: Clipping of the Inferior Mesenteric Artery using Hem-o-Lock Clips.</em></strong></p> <p>In this video, the surgical team showcases the precise technique of clipping the inferior mesenteric artery with Hem-o-Lock clips, a key maneuver in the NOSES approach.</p> <p><strong><em>Supplementary Video 3: Dissection of the Mesorectum following Total Mesorectal Excision (TME).</em></strong></p> <p>This video provides an in-depth view of the mesorectal dissection, a critical component of the NOSES procedure, following the principles of Total Mesorectal Excision (TME).</p> <p><strong><em>Supplementary Video 4: Delivery of the Anvil in the Sigmoid and Resection of the Rectum using the Linear Stapler Echelon 60.</em></strong></p> <p>Watch as the surgical team delivers the anvil into the sigmoid and performs rectal resection using the advanced Linear Stapler Echelon 60.</p> <p><strong><em>Supplementary Video 5: Removal of the Anvil Connection Rod at the Distal End of the Sigmoid Colon.</em></strong></p> <p>This video showcases the precise removal of the anvil connection rod at the distal end of the sigmoid colon, ensuring a seamless transition in the surgical process.</p> <p><strong><em>Supplementary Video 6: Transanal Extraction of the Opened Distal Rectal Stump for Smooth Specimen Extraction.</em></strong></p> <p>Observe the meticulous transanal extraction of the opened distal rectal stump in this video, a step that facilitates smooth specimen extraction.</p> <p><strong><em>Supplementary Video 7: Extracorporeal Resection of the Rectal Specimen and Inspection for Adequate Distal Margin.</em></strong></p> <p>This video captures the extracorporeal resection of the rectal specimen, followed by a thorough inspection to ensure an adequate distal margin.</p> <p><strong><em>Supplementary Video 8: Passage of the Head of the Circular Stapler through the Anal Orifice and End-to-End Double-Stapled Anastomosis.</em></strong></p> <p>Witness the precise passage of the circular stapler through the anal orifice, culminating in an end-to-end double-stapled anastomosis.</p> <p><strong><em>Supplementary Video 9: Positioning of the Post-operative Peritoneal Drainage Tube near the Anastomosis Site</em></strong><em>.</em></p> <p>In this video, the surgical team demonstrates the placement of the post-operative peritoneal drainage tube near the site of the anastomosis, a crucial step in the NOSES procedure.</p>
