The clinical significance of acquired jejunoileal diverticula

Abstract

Jejunoileal diverticula should not always be dismissed as asymptomatic findings, as they may be the cause of vague, chronic symptomatology and acute complications, including intestinal obstruction, hemorrhage, and perforation. Awareness of the fact that jejunoileal diverticula may cause chronic nonspecific abdominal symptoms and serious acute complications may lead to earlier diagnosis and timely treatment with lower morbidity and mortality.

A Rare Clinic Entity: Jejunal Diverticular Perforation and Ileus

“…Bu divertiküller primer olabilecekleri gibi operasyona, tüberküloza veya Crohn hastalığına bağlı sekonder de gelişebilirler. Ayrıca peristalsizm anormallikleri, intestinal diskinezi ve yüksek segmental intraluminal basınca bağlı olarak geliştiği düşünülmektedir [2]. İnce barsak divertiküllerinin çoğu genellikle konjenital Meckel divertikülleri gibi gerçek divertiküllerden veya akkiz olan multipl psödodivertiküllerden oluşur.…”

Jejunal diverticula — a rare cause of intestinal perforation

“…Acute complications reported are intestinal obstruction, hemorrhage or perforation can occur but are rare [3]. Reported in 5 to 10 % [5].Occult perforation of jejunal diverticulum is known to occur in rare cases [6].…”

A Rare Cause of Abdominal Pain: Jejunal Diverticulosis

“…2 Jejunal diverticulosis is encountered more frequently in the elderly, 3 with a mean age of about 70 years old. 4,5 The current theory on the pathogenesis of small bowel diverticular formation is that it is a result of a motor dysfunction of the smooth muscle or dysfunction in the myenteric plexus of the small bowel. 6 Uncoordinated contractions of the muscles result in local pressure, extruding the mucosa and submucosa through points of weakness, resulting in formation of diverticula, similar to the pathogenesis of esophageal and colonic diverticula.…”

“…The size of the diverticula can range from a few millimeters to more than ten centimeters. 4,8 They are usually larger and higher in number in the proximal jejunum compared to the distal small bowel. 4 Jejunal diverticulosis is generally not visible on plain radiograph images of the abdomen, 9 though distended jejunal loops may suggest its diagnosis.…”
