[Chronic intestinal pseudo-obstruction due to intestinal neuronal dysplasia type B (IND B), concerning one case].

Intestinal neuronal dysplasia type B (IND B) is an infrequent disease due to hyperplasia of the parasympathetic submucous plexus which causes alteration of intestinal motility, giving rise to symptoms of constipation and subocclusive manifestations. The disease is difficult to diagnose. It requires high clinical suspicion and should include differential diagnosis of patients with repeated subocclusive manifestations in order to make an early and correct diagnosis and avoid complications derived from unnecessary surgery that worsens the prognosis. We present the case of a 33-year-old Moroccan male who was admitted to our hospital on 2 occasions in 11 months, requiring total parenteral nutrition (TPN) for five months. The immunohistochemical analysis of the ileostomy and colostomy stoma led to a diagnosis of IND B. Eighteen months later, the patients is leading a normal life and has recovered the 25 kilos lost following the dietary indications and with the enzymatic supplements.
