Surgical Trunk Oriented Laparoscopic Right Hemicolectomy (ST-LRH) for Right-Sided Colon Cancer

Laparoscopic right hemicolectomy is a commonly utilized surgical procedure for the treatment of right-sided colon cancer. However, the high degree of difficulty in separating adjacent structures and the frequent vascular variations present in laparoscopic right hemicolectomy contribute to ongoing challenges, including unclear dissection planes, increased intraoperative bleeding, and insufficient lymph node clearance. This article proposes a combined approach that employs the surgical trunk as a guide, providing a clearer anatomical perspective and safer procedural steps. The study demonstrates all the steps of Surgical Trunk-oriented Laparoscopic Right Hemicolectomy (ST-LRH). A 67-year-old male was diagnosed with ascending colon cancer via colonoscopy and biopsy. Surgery was performed using the ST-LRH approach. The operation lasted approximately 125 min with 20 mL of blood loss. Postoperatively, no complications occurred, and the patient was discharged 7 days later. ST-LRH offers clearer exposure to the vascular anatomy of the surgical trunk and Henle trunk while reducing the risk of intraoperative bleeding. This approach is more procedural and standardized, facilitating broader adoption. Additionally, it contributes to reducing the learning curve for junior surgeons in mastering laparoscopic-assisted radical resection of right-sided colon cancer.
