Jejuno-jejunal intussusception in adults secondary to submucosal leiomyoma

Abstract

The tumor in the jejunum, almost completely obstructed the intestinal lumen and it was resected and bowel continuity was restored. Histopathological examination revealed a submucosal leiomyoma of the jejunum.

Adult Jejunojejunal Intussusception Caused by Small Bowel Leiomyoma

“…The invaginated intestine retracts the mesentery with its blood vessels, which leads first to venous and then arterial stasis. Intussusception is more frequent in childhood, and the highest incidence is recorded between the second and 12th months of life [ 1 ]. In adults, this phenomenon is a rare clinical entity, commonly diagnosed during surgeries performed for intestinal obstruction.…”

“…In adults, this phenomenon is a rare clinical entity, commonly diagnosed during surgeries performed for intestinal obstruction. The division of intussusception into juvenile and adult has great repercussions regarding the etiology, presentation of the clinical condition, time to diagnosis, and therapeutic approach [ 1 ].…”

“…Juvenile invaginations are mostly idiopathic, that is, there is no organic lesion that works as a lead point; they are functional disorders [ 1 ]. Exceptionally, intussusception occurs as a result of developmental abnormalities such as Meckel diverticulum, Henoch-Schonlein purpura, or lymphoma [ 1 ]. The clinical condition is most often characteristic, and the suspicion of intussusception can be established by clinical examination.…”

“…To confirm the diagnosis, the method of choice is ultrasonography, which achieves excellent results in terms of speed and diagnostic accuracy. Regarding the therapeutic approach, there is a general consensus that non-operative reduction of intussusception (under fluoroscopy or ultrasound control) is recommended when there are no absolute contraindications, which include suspected intestinal perforation, peritonitis, hypovolemic shock, and onset of discomfort for more than 24 hours [ 1 ].…”

Estudo retrospectivo das intussuscepções em cães

“…A ocorrência em animais idosos geralmente é relacionada a processos neoplásicos, o que está em concordância com a literatura médica. 9,10,11,12 Dentre os fatores predisponentes, deve-se ressaltar as alterações de dieta, presença de corpos estranhos, granulomas ou massas gastrintestinais, gastroenterites/ enterites infecciosas ou não, parasitismo intestinal e cirurgias prévias, além da forma idiopática, freqüente nos cães. …”
