Abstract
Background
Radiation enteropathy is a recognized complication in patients who undergo neoadjuvant radiotherapy for locally advanced rectal cancer. Routine formation of defunctioning loop ileostomy in these patients may mask the development of stricturing, terminal ileal and radiation enteropathy which later may complicate the ileostomy closure. Our aim was to assess the preventive techniques and key warning signs.
Methods
We present two cases of ileostomy closure in patients with occult, radiation-induced, terminal ileal stricture and review the relevant literature.
Results
The first case was complicated by dehiscence of the ileal anastomosis due to undiagnosed, downstream stenosis of the irradiated terminal ileum. A similar terminal ileal stricture was diagnosed in the second case by contrast fluoroscopy enabling an elective ileocolic anastomosis. The literature indicates the importance of identifying such problems prior to loop ileostomy closure.
Conclusions
Contrast studies before loop ileostomy closure are valuable in limiting the complications of radiation-induced distal ileal obstruction in selected patients.
