Intussusception secondary to a carcinoid tumor in an adult patient()

INTRODUCTION: Intussusception in adult patients represents 5% of all intussusceptions and 1–5% of bowel obstructions in adults. In contrast to pediatric patients, 90% of the time, in adults, it's caused by well-established pathologic mechanisms, such as carcinoma, polyps, diverticula, Meckel di...

Sumario:INTRODUCTION: Intussusception in adult patients represents 5% of all intussusceptions and 1–5% of bowel obstructions in adults. In contrast to pediatric patients, 90% of the time, in adults, it's caused by well-established pathologic mechanisms, such as carcinoma, polyps, diverticula, Meckel diverticula, stenosis, or benign neoplasms. Small intestine intussusceptions are more frequent, but colonic intussusceptions are caused 50% of the time by malignant neoplasms, especially adenocarcinoma. PRESENTATION OF CASE: We present a 70-year-old woman, with no relevant familial history, who presented with a 3-day symptomatology consisting of epigastric, colic, diffuse, abdominal pain of moderate intensity, which progressed till reaching a severe intensity, also referring abdominal distension, nausea, and gastrointestinal-content vomits. DISCUSSION: In adult patients, the exact mechanism of intussusception is unknown in 8–20% of the cases, however, secondary intussusception can occur with any lesion of the intestinal wall or any irritant factor in its lumen that alters normal peristaltic activity and that could serve as a trigger to start an intussusception of one bowel segment over another the most common site is the small intestine. CONCLUSION: Intussusception represents an unusual problem in adult patients; it requires a high clinical suspicion, mainly as a differential diagnosis in patients with intestinal obstruction, and it clinically presents as a subacute or chronic illness. CT represents the most useful diagnostic tool. An attempt to perform reduction procedures in small intestine intussusceptions can be done, however, in ileocolic or colonic intussusceptions, a formal resection of the segment is recommended.
