Introduction:
Intussusception occurs when one part of the intestines slides into the adjacent intestine resulting in bowel obstruction. It is a rare condition in adults, accounting for only 5% of all intussusceptions. It has multiple causes, with inflammatory fibroid polyps (IFPs) very infrequently being the cause. We present a rare case of intussusception in an adult due to an IFP.
Case Presentation:
A 72-year-old woman visited our hospital complaining of abdominal pain. Abdominal contrast-enhanced computed tomography (CT) demonstrated an ileo-ileal intussusception due to a round mass. An emergency surgery involving a partial ileal resection with laparoscopic assistance was performed. Pathological findings of the tumor showed proliferation of spindle-shaped cells, edematous stroma, dilation of lymphatic vessels, and infiltration of inflammatory cells, which were mainly eosinophils. Immunohistochemistry was positive for vimentin and SMA and negative for CD117, CD34, S-100, and desmin. Based on these findings, the tumor was diagnosed as an IFP.
Conclusion:
Bowel obstruction in adults due to intussusception is rare, and those due to IFPs are even more rare. Preoperative diagnosis of IFP is difficult, but surgeons must keep in mind that it can be a cause of adult intussusception.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
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...

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...
