Learning objectives: Describe how a  fluoroscopic percutaneous gastrostomy (PG) is performed in order to understand both the normal and the pathological findings that we can see on a computed tomography (CT) after its placement.

Background: A PG consists in inserting a catheter in the gastric chamber through the abdominal wall. Patients who need a gastrostomy are patients with either esophageal or neurological disorders that prevent proper oral nutrition, and are not candidates for long-term NGT.  

Findings and procedure details: BEFORE THE PROCEDURE:   1.- Informed consent should be signed by the patient at least a day before the intervention. In our institution the procedure is generally performed under conscious sedation and often on an outpatient basis.   2. - Review the labs and correct as necessary any coagul[...]

Conclusion: Computed tomography (CT) is the diagnostic method of choice for assessing patients with abdominal symptoms after a gastrostomy placement.   It is important to know the normal and the pathological findings after gastrostomy placement. Familiarity with the potential complications, techniques fo[...]
