Innovation of LESS-OPEN concept and its application and prospect in ovarian cystectomy

Ovarian cysts are one of the most common gynecological diseases, and laparoscopic surgery has been considered as the main approach for treating benign ovarian tumors. Laparoendoscopic single site surgery (LESS) is favored by women due to its hidden scar in the umbilicus. Combining single-port laparoscopy with open surgery (OPEN) can enhance aesthetic outcomes, reduce surgical complexity, and preserve ovarian function better. The concept of LESS-OPEN pioneered by our team in China has shown significant efficacy in treating ovarian cysts. We also pioneered the construction of a feasibility prediction scoring system for laparoendoscopic single-site extracorporeal (LESS-E) ovarian cystectomy, and established an indication system for LESS-E surgery for ovarian cysts to guide surgeons in selecting surgical approaches. This paper aims to discuss the application of the LESS-OPEN technique in ovarian cystectomy and to explore its future prospects.
