Meckel's mesodiverticular band causing an internal hernia

Obstructive internal hernia caused by mesodiverticular bands in children

INTRODUCTION The mesodiverticular band (MDB) is an embryologic remnant of the vitelline circulation, which carries the arterial supply to the Meckel diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may hernia...

Meckels Diverticulum Causing Volvulus of Ileum

The most common complications of Meckel’s diverticulum are Intestinal obstruction, gastrointestinal haemorrhage, adherence, intussusception, acute diverticulitis and rarely malignancy. Reported mechanism of intestinal obstruction in Meckel’s diverticulum include invagination, adherence and volvulus. Obstruction of ileum caused by volvulus of Meckel’s diverticulum is not a very frequent conditio...

Laparoscopic Removal of Retained Artery Forceps Causing Internal Hernia

rarer. Retained artery forceps remain inert and induce their effects through mechanical means giving rise to pressure effects resulting in abdominal pain or direct tissue/viscous injury leading to tissue strangulation or perforation of viscous leading to for example peritonitis or vascular injury resulting in hemorrhage [1]. The clinical presentation of retained intra-abdominal foreign material...

Aneurysmal Rupture of a Mesodiverticular Band to a Meckel's Diverticulum

Aneurysmal rupture of a mesodiverticular band has not previously been reported in the clinical literature. We are reporting a case of hemoperitoneum in a 51-year-old male after an aneurysmal rupture of a mesodiverticular band. This case demonstrates that in rare instances, a rupture of the mesodiverticular band leading to Meckel's diverticulum can lead to significant hemoperitoneum. This is usu...
