A vaginal foreign body is a common cause of consultation in Pediatric Gynecology. We present here a case of a 3 year-old girl who presented with a chief complaint of abdominal pain and who was found to have a battery in the vagina with severe secondary mucosal burns. We present here our management and follow-up. A 3 year-old girl presented to the Emergency Department with a 2 day history of abdominal pain and fever. On the review of systems, she had lost appetite; she had dysuria, did not have nausea and vomiting and did not complain of gynecologic symptoms. Upon examination, she was septic, had a very tender abdomen with guarding and had foul vaginal discharge. An ultrasound was performed to evaluate the appendix. The appendix was normal, but a round, button-battery like foreign body was seen in the vagina. Broad spectrum antibiotics were started and the patient was taken to the Operating Room to perform an Examination Under Anesthesia to remove the battery. Severe vaginal mucosa burns were seen during vaginoscopy and the battery could be removed using an E.N.T forceps through a 3-way scope (Figs. 1 and 2). We used a therapy of intra vaginal silver sulfadiazine and conjugated estrogens after the intervention to enhance vaginal healing. We performed another EUA in follow-up 2 weeks and 6 weeks after the initial intervention to assess the healing. Healing was complete at the 6 weeks examination. A vaginal foreign body can be a cause of abdominal pain in the Emergency Department. Caustic objects like batteries can cause severe burns to the vaginal mucosa. These burns can be effectively treated post intervention with intra vaginal silver sulfadiazine and conjugated estrogens.Fig. 1Cervix and posterior fornixFig. 2Lateral vaginal walls with severe mucosal burns
