A retrospective review to identify criteria for incorporating the Singapore flap and gracilis muscle flap into obstetric fistula repair

Objective To identify criteria to guide surgeons regarding indications for use of the Singapore and gracilis muscle flaps in obstetric fistula repair. Methods This is a retrospective case series. Obstetric fistula surgeons in Lilongwe, Malawi, have been incorporating plastic surgery techniques with the Singapore and gracilis muscle flaps since collaborating with plastic surgeons in 2016. We describe the surgical outcomes of procedures utilizing each flap individually and those using both. Results Between February 2016 and June 2019, 69 patients received a flap at the time of obstetric fistula repair at the Fistula Care Center in Lilongwe, Malawi. A total of 32 (46.4%) received a Singapore flap, 20 (29.0%) received a gracilis flap, and 17 (24.6%) received both types of flap. Conclusion Based on our outcomes, we note the possible advantage of incorporating the gracilis flap even when it is thought that the Singapore flap is sufficient. However, more data are needed.
