Objective:
Intestinal intussusception is difficult to diagnose in adults because the symptoms are nonspecific. However, most have structural causes that require surgical treatment. This paper reviews the epidemiologic characteristics, imaging findings, and therapeutic management of intussusception in adults.
Materials And Methods:
This retrospective study identified patients diagnosed with intestinal intussusception who required admission to our hospital between 2016 and 2020. Of the 73 cases identified, 6 were excluded due to coding errors and 46 were excluded because the patients were aged<16 years. Thus, 21 cases in adults (mean age, 57 y) were analyzed.
Results:
The most common clinical manifestation was abdominal pain, reported in 8 (38%) cases. In CT studies, the target sign yielded 100% sensitivity. The most common site of intussusception was the ileocecal region, reported in 8 (38%) patients. A structural cause was identified in 18 (85.7%) patients, and 17 (81%) patients required surgery. The pathology findings were concordant with the CT findings in 94.1% of cases; tumors were the most frequent cause (6 (35.3%) benign and 9 (64.7%) malignant).
Conclusions:
CT is the first-choice test for the diagnosis of intussusception and plays a crucial role in determining its etiology and therapeutic management.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
