We report a case of wandering spleen with peculiar collateral circulation resected by laparoscopic surgery. A 33-year-old woman underwent diagnosis with wandering spleen 10 years previously, but had only been under follow-up thereafter as the abdominal pain was not severe. She had severe recurring pain in the left side abdomen on exertion, a few days prior to visiting our hospital. Since contrast enhanced CT scan revealed poorly enhanced region of the wandering spleen accompanied by coiling vessel bundles suggesting splenic torsion, we performed a laparoscopic surgery. The spleen was not fixed to the retroperitoneum, but bound at 2 points by coiling vessel bundles with severe torsion; one bundle was to the splenic hilus and the other peculiar bundle was attached to the opposite side of the splenic hilus. The bundle at the splenic hilus (splenic artery and vein) had already been obstructed with fibrosis. The peculiar bundle attached to the opposite side of the splenic hilus was found to be derived from gastroepiploic vessels and formed collateral circulation of the spleen.
