Small bowel intussusception in adults

Abstract

Intussusception is the telescoping of a proximal segment of the gastrointestinal tract into an adjacent distal segment. This rare form of bowel obstruction occurs infrequently in adults. We report a case of small bowel intussusception in an adult male patient. We have also performed a literature review of this rare condition.

A case of retrograde jejuno-duodenal intussusception caused by jejunal lipoma: a case report and review of literature

“…14 Majority of the small bowel intussusception in adults are caused by benign lesions (60%), followed by malignancy (30%) and idiopathic causes (10%). 15 Of lesions that cause intussusception, site of intussusception and presence of anemia (hemoglobin <12) are independent predictors of malignancy.…”

“…21 Other modalities have also been used to diagnose intussusception, such as barium studies, abdominal ultrasonography, and endoscopic approaches such as EGD, enteroscopy, and colonoscopy. 14 Currently, the findings of retrograde enteric intussusception could not be fully diagnosed on computed tomography and sonography. However, they can be diagnosed via barium study showing "reverse claw sign", which represents part of the sheathing portion of the intussuscipiens filling but not the lumen of the intussuceptum.…”

Rare case of adult jejunojejunal intussusception secondary to angiolipoma

“…Owing to the fact that adults rarely present with this clinical triad, diagnosis is more challenging. CT of the abdomen is the preferred imaging study with a sensitivity of 71.4–87.5% and a specificity of 100% 5. An appearance of a ‘sausage-shaped’ mass in the longitudinal axis or a ‘target’ mass in the transverse axis is virtually pathognomonic 2.…”

Intussusception of terminal ileum into cecum associated with endometriosis

“…Intussusception – invagination or telescoping of a segment of bowel into an adjacent one, is typically a paediatric condition. Only 5% of total incidence has been described in adults, and 1% from these cases result in intestinal obstruction . In contrast, endometriosis occurs in up to 20% of women of childbearing age, defined by presence of extra‐uterine cavity endometriosis tissue .…”

“…Only 5% of total incidence has been described in adults, and 1% from these cases result in intestinal obstruction . In contrast, endometriosis occurs in up to 20% of women of childbearing age, defined by presence of extra‐uterine cavity endometriosis tissue . Endometriosis of ileum is rare and makes up about 3–18% of cases …”
