We report a case of gastric cancer with intestinal malrotation detected during laparoscopic surgery.A 72-year-old man diagnosed with early gastric cancer underwent laparoscopic distal gastrectomy. Before the reconstruction, we discovered that the second portion of the duodenum was not fixed to the retroperitoneum and that the Treitz ligament was not formed. The small intestine was located on the right side of the abdomen and the large intestine, on the left. Ladd's ligament was not present, and thus non-rotation type intestinal malrotation was diagnosed. Billroth I reconstruction was performed, but no procedure for the malrotation was performed.Intestinal malrotation is very rare in adults, and is more commonly found in neonates. Careful examination of images is very important, particularly in laparoscopic surgery.
