BACKGROUND: Although still experimental, natural orifice translumenal endoscopic surgery (NOTES) aims to use the natural orifices for intraabdominal surgery. Pure transvaginal umbilical hernia repair has been reported. However, mesh protection devices were used to minimize mesh contamination during mesh insertion. The authors believe that before widespread implementation of this technique, more foundational research is indicated to establish the sterility of hernia mesh insertion through this route. This prospective study aimed to compare transvaginal ventral hernia mesh insertion sterility with laparoscopic trocar-site insertion sterility to establish baseline data to help promote the safety of NOTES tranvaginal hernia repair. METHODS: This was a prospective descriptive study (Canadian Task Force classification 2A). With institutional review board approval, 10 patients undergoing laparoscopic surgery for benign gynecologic disease were enrolled in the study. Atrium Prolite mesh (polypropylene monofilament) was inserted into the vagina before and after standard surgical preparation with 10 % povidone–iodine. As a control, mesh also was inserted through a prepped laparoscopic port site. The mesh was cultured for bacterial, fungal, and viral contamination. All patients received standard infection prophylaxis that included preoperative intravenous cefazolin and metronidazole. RESULTS: The unprepped vaginal canal was cultured and demonstrated normal multiorganism vaginal flora in all 10 cases. Of the 10 skin incision mesh samples, 3 (30 %) grew bacteria, including Staphylococcus lugdunensis, a potentially pathogenic organism. In contrast, none of the prepped vaginal mesh specimens yielded any growth of microorganisms or potential pathogens. CONCLUSIONS: This study showed that a surgically prepped vaginal canal can be a sterile conduit for insertion of polypropylene mesh for transvaginal ventral hernia repair without the use of additional mesh protection. Surprisingly, the prepped vaginal conduit in our patients was more sterile than a prepped skin incision.
