Colonic intestinal duplication as a guide point associated with Waugh syndrome in an infant. First national case.

Background: Waugh syndrome is named to intestinal obstruction caused by intestinal invagination and malrotation, being a pathology rarely reported. The objective is to present the clinical case of a male infant with multiple intestinal obstruction secondary to Waugh Syndrome, having as a guide point a colonic intestinal duplication.

Case report: A 4-month-old male patient, with no previous history of importance, previously healthy, with clinical picture of mechanical intestinal obstruction, who underwent emergency exploratory laparotomy, finding colonic-colonic intestinal invagination at the level of the ascending colon, as head of invagination or guide point a cystic intestinal duplication of ascending colon and intestinal malrotation, exvagination by cabs, ileocecocolic resection was performed, which included cystic intestinal duplication, ileotransversoanastomosis and finally Ladd's procedure. His postoperative evolution was satisfactory. Currently with good evolution at 6 months of follow up.

Conclusions: Waugh's syndrome is a rare entity; despite having been described more than a century ago, its incidence continues to be rare. Colo-colonic invagination is infrequent, occurring in 2.5% of cases, generally associated with a guide point, as in our case, being extremely rare to cystic duplication of the colon, since there is no case reported in the literature.
