An unusual case of acute unilateral parotitis following abdominal surgery. Report of a case and review of the literature.

Background: Postoperative parotitis is a well known entity which can develop in patients who undergo major abdominal surgery.
Methods: We present a case of postoperative parotitis which occurred after a laparotomy for incisional hernia repair.
Results: After establishing diagnosis by ultrasonography assessment and blood chemical tests, patient was successfully treated by morphine discontinuing and antibiotics therapy.
Conclusion: Beside sialolithiasis, sitting position or dehydratation we suggest that morphine could play a substantial role in the development of postoperative parotitis.
