Retrograde Jejunoduodenal Intussusception due to a Migrated Percutaneous Endoscopic Gastrostomy (PEG) Tube: A Case Report

Abstract

We report a case of retrograde jejunoduodenal intussusception due to a migrated percutaneous endoscopic gastrostomy (PEG) tube, which was first suggested by the multidetector computed tomography (MDCT). Several such cases have been reported and have mostly been treated by surgical exploration, except for one case that was treated using a conservative approach. We present a case of a PEG-related retrograde intussusception that was successfully managed in a non-surgical manner, which showed no evidence of serious complications.

  Fig. 1 A. Portal venous phase of axial CT scan shows target lesion (arrow) at the 2nd portion of duodenum which composed of the jejunal loop as an intussusceptum and the duodenum as an intussuscipiens, and you can also notice gastric distension. B. Initial curved reformatted MPR image shows a markedly distended, fluid-filled stomach with retrograde jejunoduodenal intussusception. Balloon of the tube (arrow) is located in the 3rd portion of duodenum. C. When the balloon of the tube was deflated and reposited, the small bowel lumen was slightly decompressed. Note contrast materials in proximal duodenum injected via the PEG tube, and incompletely reduced intussusception (arrow). D. After four days, coronal reformatted MPR image shows spontaneously improved intussusception and decompression of duodenum (arrow).
