Meckel′s diverticulum-Revisited

Abstract

Meckel's diverticulum is a true intestinal diverticulum that results from the failure of the vitelline duct to obliterate during the fifth week of fetal development. In about 50% cases, it contains ectopic or heterotopic tissue which can be the cause of complications. A systematic review of literature was undertaken to study the history, incidence, embryoanatomy, clinical presentation, complication and management of Meckel's diverticulum. Although Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract, it is often difficult to diagnose. It may remain asymptomatic or it may mimic disorders such as Crohn's disease, appendicitis and peptic ulcer disease.

Meckel's diverticulitis: a rare entity of Meckel's diverticulum

“…Resection of incidental Meckel's found during laparotomy is controversial in children and adults. It is generally recommended that asymptomatic Meckel's to be resected in children during laparotomy [2, 3] given an increased lifelong risk for complications [4]. However, this approach remains debatable in adult patients.…”

A rare case of a strangulated Littre’s hernia with Meckel’s diverticulum duplication. Case report and literature review

“…The Meckeĺs diverticulum is a true diverticulum typically located on the antimesenteric border, is the result of a failure in the obliteration of the vitelline duct (omphalomesenteric duct), which connects the yolk sac to the midgut through the umbilical cord [1], [3], [14]. MD contains all four layers of the intestinal wall with its independent blood supply [3], [10], [15].…”

Meckel�s diverticulum: clinical features, diagnosis and management

“…Establishing a diagnosis of symptomatic Meckel diverticulum is difficult preoperatively. Although symptoms can appear at all ages, clinical manifestations are more widespread in childhood (10). Higaki et al (11) examined 776 patients and concluded that diagnosis in cases that present with symptoms, with the exception of bleeding, was more difficult than in those with per-rectal bleeding.…”

“…However, the diagnosis of Meckel's diverticulum is often to 6%; 40% of these complications are seen in children below the age of ten years (13) ( Table 1). The most general presentation in childhood is bleeding, which has been reported in approximately 50% of cases with symptoms related to the diverticulum (10). The most widespread complication of Meckel's diverticulum in adults is bowel obstruction, whereas this presentation occurs as the second most common complication in childhood (9,10,14).…”

“…The most general presentation in childhood is bleeding, which has been reported in approximately 50% of cases with symptoms related to the diverticulum (10). The most widespread complication of Meckel's diverticulum in adults is bowel obstruction, whereas this presentation occurs as the second most common complication in childhood (9,10,14). Intestinal obstruction resulting from Meckel's diverticulum occurs via distinct mechanisms such as: intussusception (15), volvulus (9,16), abdominal wall hernia (9,17,18), Meckel's diverticulitis (9), entrapment of the bowel loop beneath the mesodiverticular band (9,19) (Fig.…”
