RESUMO
Williams syndrome was first reported by Williams and Beuren in 1961-1962. It is a genetic disorder that is caused by a sporadic microdeletion of chromosome 7, which includes the elastin gene. The development of gastrointestinal pathology, such as diverticular disease, is associated with the deletion of this specific gene. Almost one-third of patients with Williams syndrome develop diverticular disease. The first episode of diverticulitis appears in 8% of patients, diagnosed with Williams syndrome, before the age of 40. According to the literature, in the case of complicated diverticulitis (Hinchey III) in patients with WS, the treatment is mainly surgical resection of sigmoid and colostomy (Hartmann procedure) or anastomosis. We present an interesting case with a 31-year-old male, with Williams syndrome and Hinchey III diverticulitis, who underwent laparoscopic lavage and primary closure of the perforation. To our knowledge, this is the first case in literature that a patient with Williams syndrome and complicated diverticulitis (Hinchey III) was treated this way and the results until now are encouraging.
