“…Anal canal duplication (ACD) is an extremely rare congenital anomaly of the intestinal tract. ACD presents as an extra opening of the anal canal without communication with the anorectum and is usually tubular [ 1 ]. It is more common in females, and it is usually diagnosed and treated in childhood and only a few cases remain undiagnosed until adulthood [ 2 ].…”

Anal canal duplication (ACD) is an extremely rare congenital anomaly of the intestinal tract that presents as an extra opening of the anal canal without communication with the anorectum. We present the case of a five-year-old male presenting to the pediatrician without symptoms and upon physical examination, a duplicated anal canal along the midline was discovered. The patient was admitted for surgery and the canal was removed via mucosal stripping. Postoperatively, the patient recovered well. The present study aims to expand on our knowledge of a very rare pathological entity and emphasize the importance of a complete pediatric physical examination.

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

“…Anal canal duplication (ACD) is a rare condition that is not easy to recognize [ 1 ]. It presents as a perineal orifice that ends with a tract as long as the anal canal and without any communication with the anorectum [ 2 ]. ACDs are usually detected early in the life, and only a few cases remain undiagnosed until adulthood.…”

Anal canal duplication (ACD) is a very rare condition, especially in adults. Four cases in adults are reported. In three cases, the orifice of duplication was located behind the native anus, and in one case, it was located anteriorly. In all cases, no communication between the anal canal and the tract of duplication was noted. Complete removals of the duplications were done through a perineal approach. Histology showed fibro-muscular tissue lined with a squamous epithelium. The postoperative courses were uneventful.
