“…Internal pudendal artery perforator (IPAP) flaps, which have been described in previous studies under various names and shapes, have become a valuable tool in vulva, vagina, and buttock reconstruction. [8][9][10] The pudendal thigh flap, also known as the Singapore flap, is primarily supplied by the internal pudendal artery branches. 11 Cardon et al 12 first reported the use of a unilateral neurovascular pudendal thigh flap for the treatment of complex RVFs in 1998.…”

Importance Rectovaginal fistula (RVF) is a challenging condition associated with recurrences and significant functional impairment. Objectives The internal pudendal artery perforator (IPAP) flap has become a viable option for reconstructing the vagina and perineal regions. This study aims to introduce a modified technique of IPAP flap interposition and evaluate its postoperative outcomes in the treatment of low RVF. Study Design Sixteen patients with RVF who underwent modified IPAP flap interposition between 2016 and 2021 were retrospectively enrolled. Recurrence rate, the satisfaction of vulvar appearance (Visual Analog Scale), and quality of sexual life (Female Sexual Function Index score) were followed up and analyzed. Results All patients presented with low fistula with a mean diameter of 8.3 mm. The mean width and length of the IPAP flaps were 3.8 and 6.2 cm, respectively. The mean follow-up period was 14.1 months. All patients achieved successful healing without recurrence. High satisfaction was reported for the cosmetic effect of the vulva with a mean Visual Analog Scale score of 8.4. The proportion of female sexual disorder exhibited a statistically significant reduction, decreasing from 100% preoperatively to 38% after surgery (P < 0.05). Conclusions The modified IPAP flap interposition is a reliable and safe option for repairing low RVF, with high success rates and minimal donor site morbidity. Moreover, this procedure provides a suitable volume flap and preserves the vaginal physiological environment, which benefits postoperative sexual function.
