Intestinal invagination in adults: Presentation of a case and a review of the Spanish literature

Intestinal Intussusception: A Shocking Diagnosis

“…More recently, a study conducted in 1971 reviewed 160 cases of intussusception and found that 24% of small bowel and 54% of colonic intussusceptions were of malignant origin [ 10 ]. In 1997, Azaretal conducted a retrospective review at the Massachusetts General Hospital with a total of 58 adult patients from 1964 until 1993, and he concluded that the diagnosis of intussusception was correctly done preoperatively in 32% of cases and was incorrect more often in small bowel benign intussusception which included 58 adult patients and concluded that intussusception was only correctly diagnosed preoperatively in 32% of cases, with small bowel intussusception of benign etiology the most frequently incorrectly diagnosed [ 10 ]. In a review by Hong et al, most lesions were located in the small bowel (49.5%), with most malignant tumors identified as metastatic carcinoma (48.7%), followed by lymphoma (26.2%) and GIST (21.3%).…”

“…The lack of specificity of these findings adding to the low intussusception incidence in adults, leads to a broad list of differential diagnoses, but this should not delay intervention [ 2 , 8 ]. Pain is the most common symptom [ 2 , 8 , 10 ], present in 71-90% of cases [ 2 ]. Following pain, rectal bleeding, nausea, vomiting, and changes in bowel habits were common symptoms.…”

“…Concerning laboratorial evaluation, elevations of C-reactive protein and leukocytosis are frequent [ 10 ] but non-significant unless ischemia or perforation have already developed [ 2 ]. In contrast, imaging evaluation is very often diagnostic, and in 36% of cases, the correct diagnosis can be made by ultrasound; by plain radiographs in 60% of cases, by barium enema in 36% of cases, and by CT scan in 72% of cases [ 2 ].…”

Intussusception on melanoma metastasis: A rare condition

“…In the majority of occasions there is an organic lesion that explains an intestinal invagination in adult [7], and the most common clinical sign is abdominal pain, associated with inflammatory biochemical symptoms [7].…”

“…Melanoma is a malignant tumor that develops from melanocytes found primarily in the skin, eye, meninges, and gastrointestinal mucosa from mouth to the rectum [7].…”
