Obstetrical procedures include cesarean sections, episiotomies, and assisted delivery. Medio-lateral episiotomies are recommended to expedite delivery or prevent perineal injury. The two types of episiotomies performed are the medial incision and the medio-lateral incision. Episiotomies can cause the formation of a rectovaginal fistula. Episiotomies are still commonly performed in Korea. Routine episiotomies have not been found to reduce the level of pain after the birth. The use of episiotomies also continued to increase throughout DeLee's career and after his death.
