Imaging examination of the transverse colonic duplication. (a) Abdomen film with the patient in the erect position. (b) CT scan shows a giant cyst in the abdominal cavity. (c) The arrows indicate the transverse colon and duplication.

Adjacent abdominal organs, such as the stomach, spleen, liver, and pancreas, were displaced by compression (Figure 1).
Postoperative specimen. (a) Surgical exposure of the transverse colonic duplication. (b) Removal of the transverse colonic duplication; the marked points in the figure are the locations where intestinal canals communicate. (c) Multiple cut surfaces of the transverse colonic duplication.

As a result, we decompressed the cyst by creating a small breach, disconnected the transverse colon at a distance of 10 cm from the cyst, and performed a side-to-side anastomosis (Figure 2).
Microscopic examination of the transverse colonic duplication. (a) The layers of intestinal tubes are clear, and another myenteron can be seen on the other side of the serosa, suggesting that the two intestinal tubes share the same serosa and vessel. (b) Full-thickness vasodilation of the intestinal canal and reactive proliferation of lymph nodes around the intestine.

Finally, the diagnosis of transverse colonic duplication was confirmed (Figure 3).
