Super-minimally invasive laparoscopic surgery: technical innovations and clinical research progress

Abstract:

With the continuous evolution of minimally invasive surgical concepts, operative techniques are progressively advancing from "minimal injury" toward "scarless" approaches. Super-minimally laparoscopic surgery (SMLS) is a novel surgical modality developed on the basis of conventional laparoscopic techniques through the innovation and recombination of operative elements, aiming to achieve smaller trauma and improved cosmetic outcomes. Utilizing the umbilical skin fold as a natural scar-concealing site, SMLS establishes no more than two primary operating channels (maximum diameter ≤15 mm), supplemented by auxiliary ports ≤2 mm in diameter on the abdominal wall. Combined with innovative separable surgical instruments and high-definition visualization systems, this approach provides a systematic solution to key issues such as residual access-site scarring. This review summarizes the development, technical innovations, current clinical applications, and potential aesthetic value of SMLS in the evolution of minimally invasive surgery, aiming to offer theoretical insights and research reference for its future promotion and technical refinement.
