Surgical Management of Retrorectal Tumors and Cysts

Retrorectal tumours and cysts are uncommon lesions arising in the space between the rectum and sacrum. They encompass a spectrum of congenital, inflammatory and neoplastic entities, including developmental cysts such as tailgut cysts and duplication cysts, as well as solid tumours, which may range from benign lipomas to malignant sarcomas or neuroendocrine tumours. Clinical presentation is often insidious, with nonspecific symptoms such as lower back pain, perineal discomfort or altered bowel habits. Accurate preoperative imaging—principally magnetic resonance imaging—defines lesion extent, relationship to surrounding structures and internal characteristics, guiding surgical planning. Complete excision remains the cornerstone of management to achieve histopathological diagnosis, prevent recurrence and mitigate malignant transformation. Surgical access is tailored to lesion size and location, with anterior (abdominal), posterior (perineal) or combined approaches. Minimally invasive techniques—including laparoscopy—have been increasingly adopted for selected lesions, offering reduced morbidity. A multidisciplinary team is essential, involving colorectal surgeons, radiologists and pathologists, to optimise patient outcomes and anticipate reconstructive needs or adjuvant therapies.

Surgical Management of Retrorectal Tumors and Cysts publication trend

The graph below shows the total number of articles in surgical management of retrorectal tumors and cysts across all publications each year (not limited to Nature Index journals).

Technical terms

Retrorectal (presacral) space: Anatomical region bounded anteriorly by the rectum, posteriorly by the sacrum and coccyx, and laterally by pelvic fascia, serving as the site for retrorectal lesions.

Tailgut cyst (retrorectal cystic hamartoma): A congenital multiloculated cyst arising from embryonic post-anal gut remnants, often asymptomatic but capable of infection or malignant transformation.

Neuroendocrine tumour (NET): A neoplasm originating from neuroendocrine cells, which may secrete hormones and occur rarely in the presacral region, sometimes within a cystic lesion.

Laparoscopic resection: A minimally invasive surgical technique using small abdominal ports and a camera to visualise and excise lesions with reduced postoperative pain and faster recovery.

Abdominoperineal excision: A combined anterior and perineal surgical approach that involves removal of the rectum and anus en bloc, typically used for low-lying or extensive retrorectal tumours requiring wide margins.
