Summary

Title Case Summary: "This study evaluates the safety, feasibility, and short-term clinical outcomes of a new surgical approach called Single-Port (SP) Robotic Transanal Minimally Invasive Surgery (SPR TAMIS) for treating rectal tumors."

Content:

Transanal Minimally Invasive Surgery (TAMIS) is a standard technique for treating early-stage rectal tumors. However, traditional TAMIS often faces challenges such as restricted vision and instrument crowding in the narrow rectum.

The purpose of this study is to establish a standardized surgical procedure using a single-port robotic platform, which provides better flexibility and visualization. The investigators will analyze real-world clinical cases and surgical videos to assess key outcomes, including the success of tumor resection (R0 resection rate), operative safety, and patient recovery parameters. The study aims to provide clinical evidence for this robotic technique and facilitate its standardized implementation in surgical practice.

Conditions

  • Rectal Neoplasms
  • Rectal Cancer Patients
  • Rectal Benign Lesions

Interventions

DEVICE

da Vinci SP Surgical System

This intervention involves the use of a single-port robotic platform to perform transanal excision of rectal tumors. The procedure includes robotic docking, precise tumor dissection with wristed instrumentation, and robotic-assisted closure of the rectal defect.
