An Unusual Case of Peritoneovaginal Fistula With Fimbrial Prolapse in a Post-hysterectomy Woman

A fairly uncommon differential diagnosis for chronic vaginal discharge and sexual dysfunction in post-hysterectomy women is peritoneo-vaginal fistula. It can present with or without fimbrial end prolapse. It is also a rare differential of genito urinary fistula due to its comparable presentation in post-hysterectomy women. Patients' morbidity and a number of unneeded conservative treatments, including the use of antibiotics and superfluous tests, can be brought on by surgeons' uncertainties related to its diagnosis. Prophylactic salpingectomy and proper surgical technique are essential for avoiding these problems as summarised from previous literature. Hereby, we are presenting a case of a 30-year-old woman who underwent abdominal hysterectomy and has been complaining of persistent watery vaginal discharge for a year after the procedure. As genito-urinary fistula is a common relative differential of the presenting case scenario, hence workup was done to rule it out but there were no noteworthy discoveries found from the workup. Due to the diagnostic conundrum, we scheduled the patient for a diagnostic laparoscopy that was followed by the detection of the peritoneo-vaginal fistulous tract with prolapsed fimbrial end, repair of tract followed by bilateral salpingectomy.
