A 12-month-old boy presented to a local emergency department (ED) with a 2-hour history of a protruding anal mass that had been incidentally noted when his parents had changed his diaper after a bowel movement. They had found soft stool and no blood in the diaper. The mass was pink and emanating directly from the boy’s anal orifice. This was the first such episode. He had been eating well and had had no evidence of pain.
His recent medical history was remarkable for intermittent diarrhea and bloody stools approximately 1.5 months prior to presentation. He had been transitioned to a nondairy diet due to suspected milk protein intolerance, and the symptoms had resolved. He had no recent history of constipation, producing 1 to 2 soft stools daily. His parents also reported a 1-week history of an upper respiratory tract infection with notable coughing.
The patient’s past medical history was unremarkable. He had been delivered at full term and had had no subsequent chronic pulmonary or gastrointestinal tract issues. Circumcision had been his only procedure, and he had had no associated abnormal bleeding. There were no familial genetic, neoplastic, pulmonary, or gastrointestinal tract disorders.
At the presenting hospital, the staff attempted to manually reduce the mass twice to no avail. The photographs in Figure were taken in the ED at presentation, 3.5 hours after the mass had been initially noted. A pediatric gastroenterologist at the tertiary referral center was consulted, and the decision was made to transfer the patient for further evaluation and management.
Figure. Lateral (top) and perineal (bottom) view of the anal protrusion.
On arrival at the tertiary center ED, the patient was stable with normal vital signs. No imaging or laboratory tests were obtained. A pediatric surgeon on call was consulted and came to see the patient promptly. On examination, the boy’s abdomen was full but soft and nontender. Anal examination revealed a 5-cm dark purple mass protruding from the anus. It was oozing blood but was not ulcerated. The mass was not pedunculated, and the surface was smooth.
The surgeon diagnosed incarcerated rectal prolapse and was able to reduce the mass by applying gentle pressure, first radially inward and then upward toward the body. The bowel was successfully reduced 5.5 hours after the prolapse had been initially noted. On digital rectal examination (DRE), there was good anal sphincter tone, no anal or rectal mass, and minimal blood in the rectal vault. The patient was discharged to home, and the parents were instructed to call with any episodes of recurrent rectal prolapse.
After discharge, the patient was referred to a pediatric gastroenterology clinic for follow-up. He had had a prolapse recurrence 1 day after the ED visit. His parents noted rectal bleeding but were able to reduce the prolapse at home. DRE in clinic revealed persistent blood in the rectal vault. The family was encouraged to use stool softeners to ensure soft stools, and a plan was made for colonoscopy to assess for a juvenile polyp or other lesion that could serve as a lead point.
Colonoscopy revealed a single 15-mm pedunculated polyp in the rectosigmoid colon. This was removed with a snare and sent for biopsy. The histology results revealed evidence of a juvenile polyp. The prolapse resolved after removal of the polyp.
