Colocolic Intussusception in an Adult Patient Secondary to Caecal Adenocarcinoma

Abstract

Acute intestinal invagination is the pathology of infants and small children. Its occurrence in adults is rare, and it represents 1 to 5% of intestinal occlusions often leading to the discovery of an organic cause that may be tumor. We report the case of a 72-year-old patient admitted to the emergency room of Ibn Sina Rabat, Morocco, for intestinal occlusion. The abdominal CT scan showed a voluminous intestinal invagination on a very probable heterogeneous digestive mass. The treatment was an open right hemicolectomy. The histopathological examination of the surgical specimen concluded a colonic well-differentiated adenocarcinoma with a 30% mucinous component. By review of literature, we discuss diagnostic and therapeutic procedures in emergency.

A Rare Case of Cecal Adenocarcinoma Presenting as Intussusception

“…Cecal adenocarcinoma presenting as intussusception in adults has been discussed previously as well [9][10][11][12]. The presentation is usually in older adults with an age group greater than 65 years of age being commonly involved [9][10][11][12]. Males are more likely to be affected as a result [9][10][11].…”

“…The presentation is usually in older adults with an age group greater than 65 years of age being commonly involved [9][10][11][12]. Males are more likely to be affected as a result [9][10][11]. The most common presentation is chronic abdominal pain in most of the cases [9][10][11][12].…”

Colonic Intussusception Due to a Cecal Tumor: A Representative Case

“…Colonoscopy has the added benefit of providing the opportunity for therapeutic reduction [3], but this is not always possible. In the majority of cases in adults, surgery remains the optimal management strategy for the reduction and resection of any underlying neoplastic process [4][5][6].…”

“…By far, intussusception is more common in children, with likely etiologies being Meckel's diverticulum and hyperplastic lymphoid tissue after gastrointestinal virus exposure [ 3 ]. Intestinal intussusceptions are rarer in adults, representing only 1%-5% of intestinal obstructions, often leading to the discovery of an organic cause, which may be neoplastic [ 4 ]. Segments of the enteric tract that is theoretically more susceptible to intussusception are junctions between freely moving segments and fixed segments, such as the ileum or cecum into the ascending colon.…”

“…Intussusceptions are classified according to etiology (idiopathic, primary, or secondary) and by their locations (entero-enteric, ileo-colic, colo-colic, etc.) [ 3 , 4 ].…”
