CT appearance of retrograde jejunoduodenogastric intussusception: a rare complication of gastrostomy tubes.

Case Report: Retrograde Jejunoduodenal Intussusception Caused by a Migrated Percutaneous Endoscopic Gastrostomy Tube

“…It may occur as a complication of gastrostomy tube migration. There have been only a few case reports in the English literature on this subject (9)(10)(11)(12)(13)(14)(15). Almost all of these cases were secondary to distal migration of a Foley-type catheter gastrostomy tube, which lacked an external fixation device or a bolster.…”

Reverse Ball Valve Syndrome: Retrograde Intussusception of a Duodenal Polyp

“…17 Retrograde intussusception of the jejunum after gastrectomy is a recognized complication 18,19 and has been described in association with intubation of the jejunum with feeding tubes. [20][21][22] We believe that the present case is the first description of the reverse 'ball valve' syndrome of the pylorus occurring through retrograde intussusception of a large duodenal polyp into the stomach. In the present case the result was abdominal pain, nausea and vomiting; the potential for this diagnosis may now need to be considered by the gastrointestinal surgeon.…”

Retrograde jejunoduodenogastric intussusception associated with fully functioning nonballoon nasojejunal feeding catheter: A case report

“…[ 13 , 14 ] Others have shown cases of retrograde intussusception, coinciding with a repositioning attempt of a distally migrated balloon tip catheter. [ 3 , 4 , 6 ]…”

“…It is often associated with a displaced gastrostomy tube. [3] Although the exact mechanism remains unclear, retrograde jejunoduodenogastric intussusception is assumed to be preceded by fixation of an inflated tip of a gastrostomy tube onto the mucosa of the small intestine following its migration past the gastric pylorus. Retraction of the migrated catheter (e.g., repositioning attempt) could lead to retrograde invagination of the distal small intestine with the inflated tip acting as a leading point.…”
