Summary
Obstetric anal sphincter injuries (OASIS) are severe lacerations that extend into or through the anal sphincter complex. A thorough exam in the immediate postpartum period and familiarity with the anatomy is essential for the proper diagnosis and management. There is no difference in long-term complications regarding the use of an end-to-end anastomosis or overlapping technique to repair the external anal sphincter. It is reasonable to administer a single dose of a second-generation cephalosporin as antibiotic prophylaxis with third- and fourth-degree perineal lacerations. Proper postoperative care, including the avoidance of constipation, pelvic rest, good hygiene, pain control, and short-term follow-up visits, are key to avoiding complications.
