The repair of sphincter injury following vaginal delivery is often inadequate or the injury was
undetected. The consequence is fecal incontinence. In this descriptive study, five patients underwent
sphincter repair by the “overlap” technique. Evaluation of postoperative outcomes at 3 and 12 months
showed that the Wexner fecal incontinence score at 17 - 20 score decreased to 0 - 6 score. Transperineal
ultrasound showed that all five patients healed well. Measurement of anal manometry, functional
anal canal length, resting anal pressures and squeezing anal pressures was better after surgery
