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.
