Intestinal pseudo-obstruction associated with biliary tract dilatation in a patient with systemic lupus erythematosus.

Intestinal pseudo-obstruction (IpsO) is an uncommon and severe complication of systemic lupus erythematosus (SLE). We report a patient with SLE who presented with IpsO and biliary dilatation (megacholedochus). The co-manifestation of these two conditions in SLE is unusual and has been reported only twice previously. The patient responded well to immunosuppressive treatment. IpsO is a rare but recognized manifestation of SLE that may be the presenting manifestation of the systemic disease or occur more commonly during disease course. Early recognition of IpsO is necessary to institute appropriate medical treatment and to avoid inappropriate surgical intervention.
