Intestinal pseudo-obstruction (IPO) is a rare but dangerous complication of systemic lupus erythematosus (SLE) when the patient has no other manifestations except gastrointestinal symptoms. We performed 1 patient with a 2-month history of recurrent vomiting and abdominal distension. She admitted past surgical histories of cesarean section and appendectomy. A physical examination revealed tenderness in the right lower abdominal on palpation and bowel sounds were weak, 2 to 3 bpm. An x-ray and CT of her abdomen showed intestinal obstruction. The initial diagnosis was adhesive intestinal obstruction. She received surgical treatment because her symptoms had gradually become more frequent and persistent. But she vomited again 2 weeks later after the surgery. Further immunology tests indicated that she had an IPO secondary to SLE. We treated the patient with methylprednisolone pulse for 3 days and followed by prednisone orally. The patient had a good response. Complete remission was achieved on 8 years follow-up. The importance of IPO secondary to SLE lies in an early diagnosis. After the diagnosis is established, immunosuppressive therapy should be the initial and first-line treatment, and surgical intervention is often disappointing and should be carefully avoided. It is necessary to enhance awareness of doctors to IPO secondary to SLE.
