Perforated peptic ulcer after cardiac surgery.

ABSTRACT

Although there are many causes of ulcer disease in postoperative period, hypoperfusion during cardiopulmonary bypass and advanced age are two key causes. We came across two cases of peptic ulcer perforation after coronary bypass graft surgery where these two common factors were absent. We have discussed various aetiolofical factors responsible for genesis of gastrointestinal ulcers in patients undergoing cardiac surgery using cardiopulmonary bypass.
