This article reports a case of small bowel resection and anastomosis performed via the transrectal NOTES approach using the Shurui® snake-like robotic system in a 30 kg healthy pig. After transrectal establishment of access to the peritoneal cavity, the robotic system was deployed to complete mesenteric vessel dissection, clipping, and transection, followed by bowel resection and hand-sewn full-thickness anastomosis. The specimen was retrieved transanally, and the rectal incision was closed per anally. The total operative time was 175 minutes, including 35 minutes for establishing the transrectal access and 140 minutes for robotic operation. Intraoperative blood loss was less than 10 mL, and no conversion to other approaches or intraoperative complications occurred. The animal was euthanized immediately after surgery. The findings demonstrate that the snake-like robotic system enables small bowel resection and anastomosis via the transrectal NOTES approach, with preliminary technical feasibility at the procedural execution level. However, clinical feasibility aspects such as anastomotic healing and infection control require further validation through survival studies.
