[Postoperative insufficiency of duodenal stump sutures caused by Ascaris lumbricoides].

A 43 years old female patient suffered ventricular resection (Billroth II) because of tumor. On the 11. postoperative day an Ascaris lumbricoides (with the length of 20 cm) was creeping out of the site of the draining tube onto the abdominal wall. Enteral parasites are very rare and strange reasons for postoperative duodenal suture insufficience but our case may deserve some attention considering the well known spreading of Ascaris infections.
