Abstract
Presacral cysts are cystic or cyst-solid lesions between the sacrum and rectum, almost involving adjacent pelvic floorstructures including sacrococcygeal fascia, rectum, and anal sphincter. Presacral cysts are usually benign, currently believed to arise from aberrant embryogenesis. Presacral cysts are clinically rare and the true incidence is unknown. Surgical resection remains the major treatment for presacral cysts. Unless the cysts are completely resected, recurrence is unavoidable. Recurrent cysts or hard-to-heal sinuses in the sacrococcyx cause patients extreme pain. However, the current knowledge of presacral cysts is insufficient. They are occasionally confused with other diseases such as ovarian cysts and perianal abscesses. Moreover, lack of the correct surgical concept and skills leads to palliative treatment for complex presacral cysts and serious complications such as impairing the function of the anal sphincter or important blood vessels and nerves. The consensus summarizes the opinions and experiences of multidisciplinary experts in presacral cysts and aims to provide clinicians with a more defined concept of the treatment, standardize the surgical approach, and improve the efficacy of presacral cysts.
