    Abstract:
    BACKGROUND AND AIMS: Natural orifice transluminal endoscopic surgery (NOTES) has been established in animal models and human studies, but few clinical studies have investigated transvaginal NOTES in the diagnosis of unexplained refractory ascites. We aimed to assess the feasibility, efficacy, and safety of transvaginal NOTES for the diagnosis of unexplained ascites in female patients. METHODS: A prospective study was done involving 3 female patients with unexplained ascites. After general anesthesia and disinfection, a 1.0-cm incision was made in the posterior fornix of the vagina. A gastroscope was inserted into the abdominal cavity through the transvaginal incision and an artificial pneumoperitoneum was created; NOTES peritoneoscopy was performed to scrutinize the pathologic changes. Endoscopic biopsy specimens were obtained for pathologic examination. The transvaginal incision was closed by direct suturing. RESULTS: Transvaginal NOTES for diagnostic peritoneoscopy was successfully performed in 3 patients. The mean operative time was 61 minutes. The estimated blood loss was 5 to 10 mL. The pathologic diagnoses were tuberculosis for all patients, and the symptoms and ascites disappeared after antituberculosis therapy. During the 4-year follow-up, no clinically significant adverse events occurred in any patient after NOTES. No patient experienced an annex inflammation, vaginitis, dyspareunia, or sexual dysfunction. All patients were comfortable and satisfied with the nonscarring surgical procedure. CONCLUSIONS: Transvaginal NOTES for the diagnosis of unexplained ascites is feasible, effective, and safe. This method had no long-term effect on female sexual function and is particularly suitable for women who have special aesthetic requirements.
