Small bowel obstruction caused by secondary tumors

Adult jejunojejunal intussusception caused by metastasized pleomorphic carcinoma of the lung: Report of a case

“…With varying incidences among different malignancies, such involvement has been reported in up to 5%-10% of neoplasms such as breast cancers and malignant melanoma. 39 Not only adult jejunojejunal intussusception but also small bowel obstruction caused by isolated metastases to the bowel wall were reported as extremely rare events. Idelevich et al reviewed the literature between 1988 and 2005 and found only 36 cases, 39 only one of which was due to the intestinal metastasis of a gastrointestinal carcinoma: rectal adenocarcinoma.…”

“…39 Not only adult jejunojejunal intussusception but also small bowel obstruction caused by isolated metastases to the bowel wall were reported as extremely rare events.

They proposed that every reasonable effort be made to achieve complete resection if radical surgery is justifi ed for an individual patient.…”

“…They also suggested the possibility of successful long-term survival after resection of secondary tumors. 39 It is well recognized that intestinal intussusception triggered by metastasis is a cause of bowel obstruction, and that this type of obstruction is often much more subject to potentially fatal conditions such as intestinal necrosis and rupture, and intra-abdominal or intraluminal bleeding. The clinical presentation, however, may be determined by the size, location, and tissue constitution of the metastases.…”

Ileozökale Invagination infolge Dünndarmmetastase eines Lungenkarzinoms

“…Within the small bowel, malignant lesions are responsible for approximately 6-30% of intussusceptions, whereas benign tumors, including hamartomatous polyps, Meckel's diverticuli and inflammatory lesions, account for the majority of identifiable causes [14]. Within the small bowel, metastatic lesions are by far more common than primary malignancies and intussusception is seen predominantly in patients with (lobular) breast cancer, lung cancer, malignant melanoma, ovarian cancer and renal cancer [3]. Metastatic lung cancer was identified as the lead lesion in our patient.…”

“…In general, gastrointestinal metastases caused by solid tumors are rare. Primary sites most frequently reported include lung and breast cancer as well as malignant melanoma [3,4].…”
