Comparing Outcomes of Per-Oral Image-Guided Gastrostomy With Radiologically Inserted Gastrostomy at a Quaternary...

Area of Science:

• Gastroenterology
• Interventional Radiology
• Medical Devices

Background:

• Per-oral image-guided gastrostomy (PIG) is an alternative to conventional radiologically inserted gastrostomy (RIG).
• PIG is underutilized in Australia despite a favorable complication profile in existing literature.
• This study evaluates PIG versus RIG in an Australian quaternary hospital setting.

Purpose of the Study:

• To compare the technical success rates of PIG and RIG.
• To assess and compare the incidence of major and minor complications between PIG and RIG.
• To evaluate readmission and mortality rates within three months for both procedures.

Main Methods:

• A retrospective review of electronic medical records (EMR) from January 2019 to January 2023.
• Inclusion of patients undergoing radiological-guided gastrostomy.
• Outcomes analyzed: procedural indication, technical success, complications (major/minor), readmission, and mortality within 3 months.

Main Results:

• Gastrostomy was successful in 97.8% of PIG procedures and 98.4% of RIG procedures.
• RIG had significantly higher rates of major complications (15.6% vs. 6.6%) and minor complications (14.0% vs. 2.9%) compared to PIG.
• No significant differences were observed in readmission or mortality rates between PIG and RIG.

Conclusions:

• Per-oral image-guided gastrostomy (PIG) demonstrates comparable primary success rates to radiologically inserted gastrostomy (RIG).
• PIG is associated with a significantly lower incidence of both major and minor complications.
• PIG represents a safer alternative to RIG for gastrostomy placement.
