ETIOLOGY AND IMAGING FINDINGS OF ILEUS IN ONCOLOGY PATIENTS

XVI.Balkan Congress of Radiology 2018, İzmir, Türkiye, 4 - 06 Ekim 2018, ss.54-55

Purpose: The aim of this study is to determine the etiology and

discuss multidetector computed tomography (MDCT) imaging findings

of adult oncology patients-under treatment or in follow-up for

their malignancy-presenting with ileus.

Methods: The abdominal MDCT findings of 70 oncology patients

(54 (77%) intra-abdominal, 16 (23%) extra-abdominal malignancy)

from our radiology database who had presented with ileus were retrospectively

evaluated to confirm the presence of ileus and to determine

the exact location and etiology. The patients were either under

treatment with chemo and/or radiotherapy, in the post-operative period

or in follow-up with remission.

Results: The etiology of patients included primary gastrointestinal

tumor (n=5), brid ileus due to adhesions (n=15), recurrent tumor at

the location of the old operation (n=20), at the anostomosis site of

the previous operation (n=5), as intraabdominal implants (n=13),

mechanical ileus due to stricture at the anostomosis site of the previous

operation (n=2), post-operative transmesenteric obstructive

hernia (n=3), incisional hernia (n=3), inguinal hernia (n=1), bezoar

at the level of partial gastrectomy (n=1), and post-operative abscess

at the operation site (n=2).

Conclusion: The etiology of ileus in oncology patients differs from

the other patients. To be familiar with these different etiologies and

imaging findings is essential in the establishment of this diagnosis in

oncology patients. MDCT is the main imaging method to confirm

the presence and etiology of ileus, to determine the transit zone in

mechanical obstructions and to guide the treatment.
