CT guidance for percutaneous gastrostomy and gastroenterostomy

Area of Science:

• Medical Imaging
• Interventional Radiology
• Gastroenterology

Background:

• Percutaneous gastrostomy (PG) and gastroenterostomy (PGE) are common procedures for gastrointestinal decompression or feeding.
• Traditional fluoroscopic or endoscopic guidance can be challenging or impossible in patients with specific anatomical or pathological conditions.
• Previous attempts at percutaneous endoscopic gastrostomy (PEG) may have been unsuccessful.

Purpose of the Study:

• To evaluate the efficacy and safety of computed tomographic (CT) guidance for percutaneous gastrostomy (PG) or gastroenterostomy (PGE) in patients with contraindications to standard guidance methods.
• To determine the success rate and complication profile of CT-guided PG/PGE in a challenging patient cohort.

Main Methods:

• Retrospective analysis of 22 patients undergoing CT-guided PG or PGE.
• Indications included gastrointestinal obstruction (n=15) and feeding access (n=7).
• Reasons for CT guidance included esophageal obstruction, inability to tolerate gastric distention, abnormal gastric morphology, and concurrent procedures.

Main Results:

• Successful catheter placement was achieved in all 22 patients.
• No major complications were reported during or after the procedures.
• CT guidance facilitated PG/PGE in cases where fluoroscopic or endoscopic methods were not feasible.

Conclusions:

• CT guidance is a valuable and safe technique for performing percutaneous gastrostomy (PG) or gastroenterostomy (PGE) when standard methods are precluded by anatomical or pathological issues.
• This imaging modality expands the applicability of percutaneous feeding and decompression procedures to complex patient populations.
• CT-guided interventions offer a reliable alternative for gastrostomy placement in challenging clinical scenarios.
