In an 18-year-old man who had noticed an abdominal mass sometimes changing the size since 2 years age, a 15×10cm tumor with elastic hard and well-defined border was palpated in the upper abdomen. Fluoroscopic examination of the stomach revealed that it was pushed up. Abdominal plain X-ray film taken after several days showed a residual barium in a cystic form 15×10cm in size at the median. Barium enema revealed a communication between the cystic portion and the transverse colon at the splenic flexure. From these findings the patient was diagnosed a transverse colon duplication and underwent laparotomy. The duplicated intestine arose from the transverse colon near the splenic flexure, and existed between the anterior and posterior leaves of transverse mesocolon. The feeding artery branched directly from the superior mesenteric artery. The cystic duplicated intestine was excised and the end was sutured. Histologically it had normal structure of large intestinal wall.
This paper also describes a discussion of 54 cases of the disease reported in Japan.
