5. CNCLUSION
Intussusception in the adult population is often associated with
underlying pathology. Considering that adult intussusception is a rare
entity with inaccurate medical history and clinical examination. Imaging
method evaluations are needed for diagnosis. Primary small bowel DLBCL
can present a variety of clinical manifestations, which shows the
importance of a highly suspected clinically, which is helpful for rapid
diagnosis and subsequent treatment. Thus, learning aim based on this
extremely rare case report, we can learn that its clinical
manifestations, morphological characteristics, immunophenotypes and
molecular biological characteristics are very different and important,
which is challenging to preoperative diagnosis. Clinicians and surgeons
should keep this in mind in the assessment of patients with intestinal
obstruction, and should always be kept in the differential diagnosis of
intussusception, especially in the older age or children groups.
Emergency surgery is an option to treat severe intussusception. The
diagnosis for localized intestinal DLBCL is usually confirmed by
histopathology and IHC examination after obtained surgical specimen.
Surgery, chemotherapy, radiotherapy and or immunotherapy is a different
application of its management, may be in a different combination.
