“…4 Histologically, rectal duplication cysts have smooth muscle present with a surrounding squamous epithelial segment, as well transitional epithelium. 5 The consensus diagnosis for the above case was an anorectal duplication. The lesion was adherent to the anal canal but did not communicate with it, and was separate from the anal sphincter complex, consistent with an anal canal duplication.…”

A 4-year-old female presented with a perianal opening on a background of chronic constipation, mucus discharge from the perianal area and abdominal pain since birth. On initial examination, there was a small pinhole, external, opening at 6 O'clock with a prominent external anal blood vessel. Ultrasound showed a small opening adjacent to the anus and a small tract measuring 12 Â 2 mm opening along the anal canal. Further imaging with magnetic resonance imaging showed an anteriorly positioned rectum, with loss of normal vertical anorectal angle, and an abnormality anterior to the sacrum and paralleling the anal canal down to the anal verge. Both internal and extrinsic anal sphincters had a normal appearance. The probable diagnosis was of a collapsed sinus and the patient underwent an examination under anaesthetic which showed a 2-cm deep perineal tract that had no communication with the anorectum. The patient had no urogenital or spinal anomalies.The patient underwent surgical excision of the ano-perineal tract; she was admitted 2 days prior to surgery for bowel preparation due to her longstanding constipation. The patient was positioned prone, and a circumferential incision was made around the external opening and extended posteriorly in the sagittal plane. Bipolar diathermy was then used to dissect proximally with the aid of a nerve stimulator to identify muscle complex. The posterior wall of the tract was continuous with the rectal wall. The tract was traced proximally to its blind-ending and excised. There was no connection or breach of the rectum. The

“…Second, surgical resection of the rectal duplication eliminates the otherwise persistent risk of complications, such as bleeding, perforation and malignant degeneration 7–9. Several surgical techniques have been previously described in the literature for the treatment of rectal duplications, including parasacral, transanal, perianal and abdominal approaches 18–28. The size and location of the lesion, along with surgeon’s experience should be considered when choosing the operative technique, for there is no consensus about the best surgical approach 9 29–31.…”

“…The size and location of the lesion, along with surgeon’s experience should be considered when choosing the operative technique, for there is no consensus about the best surgical approach 9 29–31. The parasacral approach may be appropriate for small lesions located posteriorly to the rectum; its major disadvantages are the risk of intraoperative pelvic haemorrhage and injury to the lateral pelvic nerves 19 29. Transanal excision may be convenient for small low-lying rectal duplications but can be technically challenging 20–22.…”

Rectal duplication cyst in an adult with a history of imperforate anus: a diagnostic challenge

et al. 2022

View full text Add to dashboard Cite

Rectal duplications are rare congenital anomalies that represent 1%–6% of alimentary tract duplications. We report a case of a woman in her 50s who presented to our hospital with perianal pain and urinary retention. She had a history of imperforate anus repaired after birth and dynamic graciloplasty performed during her adulthood for faecal incontinence. Abdominal CT scan showed a fluid collection extending from the electrostimulator, placed in a subcutaneous pocket in the abdomen, to the rectouterine pouch. Infection related to the electrostimulator was assumed and, after a course of antibiotics without patient improvement, the electrostimulator was removed. The symptoms and the pelvic fluid collection persisted, and diagnostic laparoscopy was performed. Diagnosis of rectal duplication cyst was made intraoperatively, and the cyst was completely resected. Patient fully recovered after surgery. This is a rare case of a rectal duplication cyst presenting during adulthood and associated with imperforate anus.

BackgroundCongenital perineal hamartomas are rare, and reports of prenatal ultrasound diagnosis are limited. Perineal hamartomas are usually associated with other structural malformations, which complicate the therapeutic regime.Case presentationWe report a case of perineal hamartomas associated with rectal duplication in a female fetus. A review of the literature on similar cases was also presented. A fetus was first diagnosed with a perineal mass at 33 weeks of gestation using ultrasound examination in our hospital. Two-dimensional ultrasonography showed a hyperechoic mass resembling a scrotum in the perineum of the fetus. The pedicle connected the mass to the fetal anus. The masses were excised after birth, and perineal hamartomas were confirmed by pathological diagnosis. Rectal duplication, an associated malformation, was found during the surgery. The rectal duplication cyst was removed at the same time.ConclusionCongenital perineal masses are rare and are usually associated with urogenital and anorectal malformations. Prenatal ultrasound should be used to assess the position and relationship between the mass and perineal organs, and to exclude other combined deformities.
