Intestinal Obstruction Due to Vitelline Vascular Remnants Treated by Single-incision Laparoscopic-assisted Surgery

A 37-year-old man was admitted to the hospital with complaints of abdominal pain and vomiting. Abdominal CT revealed an intestinal obstruction. Ileus was cured by conservative medical treatment. He had no history of abdominal operation. We performed single-incision laparoscopic surgery through an umbilical incision for diagnostic purposes. At surgery, we found a band extending from the ileum, 40 cm proximal to the end of the Bauhin’s valve, and adhering to the right medial umbilical fold. Pathologically, it was found to contain an artery and vein, and was diagnosed as vitelline vascular remnants. In Japan, the number of reported cases of vitelline vascular remnants without Meckel’s diverticulum is extremely low. To the best of our knowledge, this is the only case of vitelline vascular remnants without Meckel’s diverticulum treated by single-incision laparoscopic-assisted surgery in Japan.
