Percutaneous Radiologic Gastrostomy Placement in Challenging Clinical Scenarios.

Percutaneous radiologic gastrostomy is indicated for patients who require enteral access for nutritional support, medication administration, and/or decompression. Some patients have comorbidities that increase procedural risk and may require deviation from the conventional approach, such as upper gastrointestinal tract obstruction, ascites, and postsurgical anatomy. In such cases, technical modifications and/or changes to the standard approach may be needed. This review describes several specific scenarios that require special consideration, focusing on clinical management options, risk mitigation techniques, and supportive evidence.
