Hereditary cancer syndromes such as BRCA1/2 and Lynch syndrome significantly increase the lifetime risk of ovarian, fallopian tube, and endometrial cancers. Risk-reducing salpingo-oophorectomy (RRSO) and hysterectomy are standard preventive strategies. Vaginal natural orifice transluminal endoscopic surgery (vNOTES) has recently emerged as a minimally invasive, scarless alternative that may enhance patient acceptance while maintaining oncologic safety. This narrative review aims to synthesize the current evidence regarding the role of vNOTES in risk-reducing gynecologic surgery for women with hereditary cancer syndromes, focusing on surgical feasibility, technical considerations, oncologic safety, and patient-reported outcomes. A structured literature search was conducted in PubMed and Web of Science for studies published between January 2000 and April 2025, using terms related to vNOTES, prophylactic gynecologic surgery, BRCA mutations, and Lynch syndrome. Inclusion criteria focused on studies reporting outcomes of vNOTES in risk-reducing or oncologic contexts. A total of eight studies were included for qualitative synthesis. vNOTES has demonstrated technical feasibility and favorable surgical outcomes in risk-reducing procedures such as RRSO and hysterectomy in BRCA and Lynch syndrome carriers. Comparative studies report lower postoperative pain, faster recovery, and high patient satisfaction, with oncologic standards maintained through specimen containment, peritoneal inspection, and adherence to the SEE-FIM protocol. Limitations include the learning curve and restricted access to the upper abdomen, which may necessitate hybrid approaches in selected cases. vNOTES offers a promising, patient-centered surgical approach for hereditary cancer prevention, combining oncologic safety with enhanced recovery and cosmetic benefits. Further research is needed to standardize protocols, evaluate long-term outcomes, and define its role within broader personalized cancer prevention strategies.
