Endometriosis presenting as vaginal polyps: outpatient vaginoscopic treatment

Abstract

Objective: To demonstrate an outpatient vaginoscopic technique for treating multiple vaginal polyps. Design: Demonstration of surgical technique using slides, pictures, and video. Setting: Private hospital. Patient(s): Thirty-two-year-old nulligravid woman presenting to the gynecology clinic with one episode of intermenstrual bleeding, regular menstrual cycles with normal flow, and no history of dysmenorrhoea or dyspareunia. The genital local examination was normal, and speculum examination showed multiple vaginal lesions like polyps in the proximal posterior two-thirds and right lateral vaginal walls. Her transvaginal ultrasound read a normal uterus with a right ovarian simple cyst. Intervention(s): The surgeon performed an outpatient operative vaginoscopy using a 5-mm continuous flow office hysteroscope with a 2.9-mm rod lens optical system and a 5F working channel. Distension of the vagina was achieved with a normal saline solution, and an intrauterine pressure of 50 to 60 mm Hg was maintained by an irrigation and aspiration electronic pump. An inspection of the vaginal walls, fornices, and the external cervical os (Fig. 1) revealed 10 vaginal lesions like polyps in the proximal two-thirds of the posterior and right lateral vaginal wall. The vaginal lesions (Fig. 2) varied in size from 0.5 cm to 4 cm. An excisional biopsy was performed and the sample sent for histopathologic evaluation. The vaginal lesions <2 cm in length were excised by cutting the base with scissors or using a bipolar vaporization electrode, which was connected to an electrocautery unit by a bipolar high-frequency cord. Vaginal lesions >2 cm were excised with the TruClear 5C Hysteroscopic Tissue Removal System (HTRS) with a zero-degree scope using the 2.9-mm incisor with a 5-mm cutting window at one end attached to a reusable handpiece with two connectors-one to the motor unit and second to the suction bottle with a collection bag. The overall diameter of TruClear 5C is 5.7 mm, and the optic size is 0.8 mm. The same irrigation pump is compatible with HTRS, and the pressure was increased to 150 mm Hg to maintain vaginal distension. Three factors influenced our decision to use the HTRS intraoperatively: the number and size of the vaginal lesions and the surgical time in the outpatient setting. A mechanical system that works on the principle of excising and aspirating tissue, the HTRS incisor has a rotatory action with the excising window placed against the most distal part of the vaginal lesions. The cutting action is controlled via a foot pedal attached to a motor control with 800 rotations per minute. The handpiece remains stationary while the polyp is excised and aspirated through the window into the collection bag. Minimal bleeding occurred and stopped spontaneously. The institutional ethics committee exempted this case report from review, and we obtained informed written consent from the patient. Main Outcome Measure(s): All vaginal lesions excised in an outpatient setting via vaginoscopy technique without anesthesia. Result(s): The opera...
