Materials and Methods: Patients who have complications due to postoperative radiotherapy for abdominopelvic cancer (n=119) were retrospectively compared with 207 cases, who did not receive radiotherapy between 2005-2008. Patients were retrospectively evaluated according to the age, gender, primary disease, time of the occurrence of complications following the radiotherapy, accompanied disease, BMI, applied surgical methods, mortality and morbidity. Peritoneal carcinomatosis and complications related to other causes than radiation were excluded from the study.

Results : Fifty eight (48,7%) of patients who received radiotherapy did not require surgical repair, but 15 (12,6%) received surgical procedure. 5 (4.2%) of these patients died. In patients who did not received radiotherapy, number of complications which required surgical approach was only 3 (1.4%). There was a statistical significance between irradiated group and control group, according to gastrointestinal hemorrhage, ileus, fistula, proctitis, cystitis, enteritis and reoperation requirement (p<0,05; for fistula, proctitis, cystitis and p<0,001 for all other parameters ).

Conclusion: Number of complications are increasing in patients receiving radiotherapy following the surgery for abdominopelvic malignancies. Preoperative nutrition is very important in patients who require surgery for these complications. Preferred surgical method and technique is crucial in these cases. Diversion and bypass procedures should be considered.
