    Abstract:
    Chronic intestinal pseudo-obstruction (CIPO) is a heterogeneous group of rare disorders characterised by symptoms of intestinal obstruction with no mechanical evidence of obstruction. It is caused by ineffective intestinal contractions due to visceral neuropathy and/or neuropathy. In adults, CIPO is mostly secondary. The most common causes are metabolic disorders, connective tissue disorders, neuropathic drug related injuries, paraneoplasic and post-infectious syndromes and amyloidosis. Secondary forms of CIPO have been reported with anti-Hu antibodies. This corresponds to an antineuronal antibody that recognizes a protein expressed in the nuclei of neuron (ANNA-1) and neoplasic cells. The anti-Hu antibody must be searched for in patients over 40 years old with CIPO (associated with small cell lung cancer in 75% of cases). Recently, the association of CIPO and the anti-Hu antibody has been described without associated neoplasia. We report a case of an association of CIPO and anti-Hu antibody without cancer after 13 years of follow-up.
