Palliative Interventional Radiology for Malignant Bowel Obstruction

Gan To Kagaku Ryoho. 2025 Oct;52(10):705-709.ABSTRACTIn interventional radiology (IR) for malignant bowel obstruction, treatment is broadly classified into drainage and stent placement. In cases such as terminal-stage malignancy, where removal of a nasogastric or ileus tube is unlikely, gastrostomy or stent placement may be performed endoscopically. However, for patients in whom endoscopic gastrostomy is difficult-such as those with anatomical or procedural limitations-IR-guided access for gastrointestinal decompression can be considered. Representative procedures include percutaneous radiologic gastrostomy (PRG), also referred to as radiologically inserted gastrostomy (RIG), and percutaneous transesophageal gastro-tubing (PTEG). In specific cases such as afferent loop syndrome, stent placement through…
