Management of Fourth Degree Perineal Tear: A Case Report

Perineal trauma, particularly third- and fourth-degree tears, poses a significant concern in obstetric care due to its association with short- and long-term morbidities, including faecal incontinence, pain, dyspareunia, and social and psychological complications like depression. The risk of severe perineal tears increases with factors such as large birth weight, instrumental deliveries, and prolonged labour. Accurate diagnosis, effective management, and appropriate repair techniques are crucial for preventing complications and promoting recovery. This report discusses a case of a 33-year-old woman who presented with a 10-year history of faecal and flatus incontinence, with faeces passing through the vagina. Her obstetric history included three full-term home vaginal deliveries, marked by significant blood loss in the last two deliveries. Examination revealed a fourth-degree perineal tear with the absence of a separate anal opening and significant fibrosis, highlighting the complexities of managing such injuries. Surgical repair was performed using the Warren flap method. Postoperative management involved a liquid diet, antibiotics, and careful monitoring to prevent complications like wound dehiscence and delayed complications such as rectovaginal fistula. The patient’s postoperative course was uneventful, and follow-up assessments showed marked improvement, with complete healing at three months. The case emphasises the importance of skilled surgical intervention, tailored postoperative care, and comprehensive follow-up in optimising outcomes for patients suffering from severe perineal trauma.
