Colorectal tubular enteric duplication

Abstract

Case presentation A 6-month-old female infant with an absent left thumb ( Figure 1) was referred to a pediatric surgeon because of rectal prolapse. She was the full-term product of an uncomplicated pregnancy. Physical examination showed a pelvic mass anterior to the rectum. Therefore, a pelvic sonogram ( Figure 2) and computed tomography ( Figure 3) were obtained. The pelvic sonogram showed a fluid-filled tubular structure separate from the uterus anteriorly, and from the rectum posteriorly. The computed tomography scan confirmed this slightly left-sided tubular structure. At the time of the CT, no contrast given orally was seen to enter the left-sided tubular structure. The child was taken to the operating room for a better evaluation by means of cystoscopy, vaginoscopy and colonoscopy. Cystoscopy and vaginoscopy were normal without a bladder septation or fistula being identified. A small pit was identified in the rectal wall just above the anus, which was catheterized and contrast injected (Figure 4).The contrast enema at the time of colonoscopy showed a tubular colorectal duplication communicating with the distal Figure 1 Single frontal radiograph of the left hand. The thumb is absent. Figure 2 Longitudinal sonograms of the pelvis. Longitudinal (a) and transverse (b). Behind the uterus (Ut) and anterior to the rectum (R) is a tubular structure (arrow) with an echogenic central structure, related to the mucosa, and a hypoechoic periphery related to the muscular wall. These findings are the characteristic sonographic signatures of the bowel.

“…10 Extensive work in animal models of gastrointestinal duplication has shown a very close relationship of this duplication with the presence of notochordal and spinal abnormalities, such as spina bifida and split notochord syndrome. 11 The absence of spinal or neurological abnormalities in this patient makes this unlikely.…”
