A Case of Transanal Total Mesorectal Excision Using the Senhance Digital Laparoscopy System for Rectal Cancer

Le résumé fourni par la source

INTRODUCTION: This case report presents the world's first transanal total mesorectal excision (taTME) using the Senhance Digital Laparoscopy System for rectal cancer. Senhance has been gaining attention as an advanced surgical robot, providing better visualization, stable dissection, and reduced surgeon fatigue compared to conventional methods. CASE PRESENTATION: A 68-year-old woman underwent Senhance-assisted taTME for a rectal tumor located 4 cm from the anal verge. The procedure was completed safely with a total operation time of 209 minutes, a cockpit time of 85 minutes, and a blood loss of 40 mL. Pathological evaluation confirmed complete resection (R0) with no residual cancer or lymph node metastases. The patient was discharged on postoperative day 7 without complications. CONCLUSIONS: This case demonstrates the potential advantages of Senhance-assisted taTME, including improved visualization, stable dissection, and reduced surgeon fatigue. Further studies are needed to evaluate long-term outcomes and establish the role of this technique in rectal cancer surgery.
