Application and exploration of single-incision plus one port laparoscopic surgery in radical resection of colorectal cancer

The surgical management of colorectal cancer has evolved from conventional multiport laparoscopic surgery toward more minimally invasive and individualized approaches. Among these, single-incision laparoscopic surgery (SILS) or reduced-port laparoscopic surgery (RPLS) has gained increasing attention from clinicians. Single-incision plus one port laparoscopic surgery (SILS+1) combines the advantages of both SILS and RPLS. Recent studies have demonstrated that compared with conventional multiport laparoscopic surgery, SILS+1 could yield comparable safety, feasibility and oncologic outcomes in treating colorectal cancer while offering additional benefits in enhanced recovery and better cosmesis.The development of SILS+1 relies heavily on innovations in single-port platforms and specialized instruments. By strictly adhering to its indica-tions, skillfully employing string and traction techniques during surgery, and the appropriate mana-gement of complications such as hemorrhage, the procedure can be performed safely and smoothly. The authors review relevant domestic and international studies and integrate the practical experi-ence to provide an in-depth discussion on the application and exploration of SILS+1 in radical colorectal cancer surgery, aiming to provide valuable insights for broader adoption of this approach.
