Inverted Meckel's Diverticulum with Intussusception and Ulceration Diagnosed after Rectal Double-Balloon Enteroscopy

Intussusception due to an Inverted Meckel’s Diverticulum Diagnosed by Double-Balloon Enteroscopy

“…Since Meckel's diverticula are usually 70–100 cm from the ileocecal valve, DBE can pave the way to establish the diagnosis of an inverted Meckel's diverticulum resulting in intussusception. The endoscopic findings of an inverted Meckel's diverticulum with ulceration and intussusception in this report are consistent with a previous publication [ 9 ]. The intussusception was partially reduced by injecting contrast medium after wedging the balloon to prevent distal flow, which relieved the obstruction.…”

A Pediatric Case of Inverted Meckel’s Diverticulum Presenting with Cyclic Vomiting-like Symptoms: A Case Report and Literature Review

“…In the literature review including the present case, bloody stool was observed in 55/74 (74.3%) of adults and 3/9 (33.3%) of children, with a significant difference ( p = 0.019) ( Table 1 ). Although it may not be sufficient to conclude that the diagnosis of inverted Meckel’s diverticulum is usually delayed in pediatric cases because of the absence of bloody stool, eight pediatric cases, excluding the present case, resulted in ileus due to intussusception, and imaging findings of intussusception were observed significantly more often in children than in adults ( p = 0.001) [ 2 , 3 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. On the other hand, adult cases may have significantly more anemia due to chronic intestinal hemorrhage ( p < 0.0001) ( Table 1 ), because the adult cases do not present with the acute onset of intussusception, unlike the pediatric cases.…”

“…In total, 94 related articles were retrieved. There were 29 articles for 74 adult [ 3 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ] and 9 pediatric (age < 18 years) [ 2 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ] cases including the present case] that reported the course of each case in detail. These included 55 male and 28 female patients with onset ages of 2 to 78 years.…”
