A 50-year-old female with squamous cell carcinoma of the lower third of the esophagus underwent an esophagectomy via laparotomy and right thoracotomy. She developed a major anastomotic leak on the third postoperative day. The chest tube slipped out on the 10th postoperative day and a segment of Taenia saginata tapeworm came out through the tube drain site and was extracted. She was given praziquantel tablets treatment; after which the leakage dropped dramatically and ceased completely after one week. Patients scheduled for esophagectomy who experienced recurrent abdominal pain in areas endemic with a tapeworm need to be screened for taeniasis before surgery.
