Abstract

Chronic intestinal pseudo-obstruction (CIPO) is a severe gastrointestinal syndrome characterized by disruption of normal gut movement, resembling a mechanical obstruction, despite the absence of any physical obstruction. It can occur idiopathically or as a secondary manifestation of various underlying conditions, such as certain genetic disorders. Chronic atrial and intestinal dysrhythmia (CAID) is one of the rare causes of CIPO. This syndrome is an autosomal recessive cohesinopathy in which the SGOL1 (K23E) mutation disrupts cardiac and intestinal pacemaker cells, leading to sick sinus syndrome (SSS) and chronic intestinal pseudo-obstruction (CIPO). In this case report, we present a 10-year-old male patient with severe gastrointestinal symptoms. After conducting all diagnostic procedures, the patient was diagnosed with Chronic Intestinal Pseudo-Obstruction (CIPO), and further genetic testing confirmed CAID as the underlying cause of his condition. Pharmacological treatment was administered, and a clinically significant response was observed. When other causes are ruled out, and the patient also exhibits cardiac symptoms, we should consider CAID. We recommend considering genetic counseling for investigating underlying causes, such as CAID, in cases of CIPO.
