A 74-year-old man who had undergone partial gastrectomy (Billroth I) for a gastric
tumor 15 years previously was admitted to our hospital for post-stroke rehabilitation.
Being dysphagic, he was transferred to our hospital with a nasogastric tube; however,
long-term tube feeding was deemed necessary and, after careful evaluation, a percutaneous
endoscopic gastrostomy (PEG) was performed in an interventional radiology suite with
the use of fluoroscopy. A bumper tube-type catheter was inserted using the push technique
(Boston Scientific Safety PEG Kit; Natick, Massachusetts, USA) by puncturing the anterior
wall of the remaining stomach just before the anastomotic site ([Fig. 1]).

tube positioned within the stomach.
Although the procedure ended uneventfully, hematemesis occurred after a few hours.
An upper gastrointestinal endoscopy revealed blood oozing from the PEG site with no
bleeding lesions within the stomach. An abdominal computed tomography (CT) scan showed
the PEG tube had been placed through the lateral segment of the liver ([Fig. 2]), confirming a mispuncture during the procedure. The bleeding eventually stopped
with the use of antibleeding agents and tightening of the external bolster of the
PEG catheter. The patient was transferred to the rehabilitation ward 30 days after
the procedure without further complications.

An interposed organ is usually considered an absolute contraindication for a PEG and
liver injury (mispuncture) is a rare complication [1]. However, in patients with a previous gastric resection, the remnant stomach is
usually overlaid by the transverse colon or the left lobe of the liver, meaning these
organs are at risk of injury during PEG insertion. Although in such cases a transhepatic
approach to PEG has been suggested to be feasible [2], the risk of postoperative hemorrhage and other complications should be given due
consideration [3]. When a PEG is not suitable or cannot be performed safely, a minimally invasive
esophagostomy procedure, known as percutaneous transesophageal gastro-tubing (PTEG),
may be a more appropriate alternative to achieve percutaneous tube feeding without
the need for a laparotomy or laparoscopy [4]. Another option would be jejunal feeding using direct percutaneous endoscopic jejunostomy
(D-PEJ) [5].
