The patient was a 10-month-old boy who was referred to our hospital because of an abdominal mass. From the findings of abdominal CT and contrast enema, a tubular duplication of the colon from the transverse to the sigmoid colon was suspected. Laparoscopic-assisted surgery was conducted. It was found that the expected entrance was a fistula formed in the common wall of the transverse colon, and the duplicated intestinal tract was extended to the 15 cm oral from the ileum end, which was impossible to separate from the normal intestine. After consultation with the family, a total colectomy with ileorectal end-to-end anastomotic reconstruction was performed. One year after surgery, the patient is doing well despite needing antidiarrheal agents. While it has been stated that colon duplication should be treated by complete resection, this is Japan’s first pediatric report of the total resection of the colon because of colon duplication. While the short-term results are satisfactory, the appropriateness of the procedure needs to be determined or middle- to long-term follow-up.
