 A very rare case of polyarteritis nodosa (PAN) with penetration of the small intestine to the mesostenium treated by laparoscopically assisted surgery is herein reported. A 66-year-old woman was admitted with the chief complaints of abdominal distention and vomiting. Radiologic enteroclysis after decompression used the long intestinal tube revealed incomplete stenosis at the small intestine. Abdominal CT revealed parenteral gas in the mesostenium. Penetration of the small intestine to the mesostenium was suspected and laparoscopically assisted surgery was performed. Penetration site was detected laparoscopically, and partial resection of the small intestine was performed by minilaparotomy. Histologically, the lesion of the ulcer was diagnosed as PAN. Postoperative course was uneventful. Oral administration of steroid was started, and the patient was discharged 11 days after surgery. There has been no recurrence.
