The advancement of laparoscopic minimally invasive techniques has driven the surgical treatment of colorectal cancer toward greater minimal invasiveness. As the “ultimate minimally invasive procedure”, natural orifice specimen extraction surgery (NOSES) has emerged as a crucial development direction in colorectal surgery due to its advantages including mild postoperative pain, fewer incision complications, rapid recovery of gastrointestinal function, and excellent cosmetic outcomes. Caudal approach laparoscopic radical resection of right colon cancer conforms to oncological radical principles, shortens the surgical learning curve, ensures surgical safety, and offers unique advantages over other approaches in terms of the completeness of lymph node dissection and perioperative patient recovery. Based on the Chinese Expert Consensus on the Definition and Nomenclature of Mesentery, Fasciae and Planes in the Colon and Rectum (2023 Edition) and relevant clinical research evidence, this article reports the application of caudal tunnel three-dimensional through-and-through technique and reciprocating vascular skeletonization technique in the performance of radical resection of right colon cancer with transvaginal specimen extraction and no auxiliary abdominal incision (NOSES ⅧA procedure) in municipal hospitals. It also discusses the surgical techniques, clinical safety and application value of this procedure, providing a reference for municipal hospitals to perform NOSES for right colon cancer.
