Computed Tomography-guided Drainage with Modified Trocar Technique Using a Drainaway Drainage Kit

Area of Science:

• Medical Imaging and Interventional Radiology
• Surgical Devices and Technology

Background:

• Image-guided percutaneous drainage is a standard, safe, and effective treatment for abscesses.
• Traditional methods may involve radiographic fluoroscopy, adding complexity and radiation exposure.

Purpose of the Study:

• To investigate the feasibility and safety of the Drainaway computed tomography-guided percutaneous drainage kit.
• To evaluate the efficacy of Drainaway for abscess drainage without radiographic fluoroscopy.

Main Methods:

• A retrospective observational study analyzed 28 procedures in 27 patients using the Drainaway kit.
• Inclusion criteria: symptomatic, CT-puncturable, and refractory abscesses.
• Outcomes assessed: technical success, primary and secondary clinical success, and complications.

Main Results:

• High technical success rate of 96.4% was achieved.
• Primary clinical success rate was 77.8%, with a secondary clinical success rate of 96.3% after catheter adjustment.
• A single complication of biliary pleurisy requiring drainage was reported.

Conclusions:

• The Drainaway kit is a valuable tool for abscess drainage.
• It allows for effective and safe procedures solely under computed tomography guidance, avoiding radiographic fluoroscopy.
