Percutaneous gallbladder drainage is often challenging. Most patients require a transhepatic approach due to liver or colon interposition, impacting gallbladder access.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Abdominal Anatomy

Background:

  • Percutaneous cholecystostomy is a minimally invasive procedure for gallbladder drainage.
  • Assessing the feasibility of different percutaneous access routes is crucial for successful intervention.

Purpose of the Study:

  • To evaluate the anatomical relationships between the gallbladder fundus, liver, and right hemicolon.
  • To determine the feasibility of direct transperitoneal versus percutaneous transhepatic cholecystostomy.

Main Methods:

  • Retrospective analysis of 100 consecutive patients undergoing abdominal computed tomography (CT).
  • Evaluation of the spatial relationship between the skin, gallbladder fundus, liver, and right hemicolon.

Main Results:

Related Experiment Videos

  • In 83% of patients, the gallbladder fundus was not directly accessible from the skin without liver or colon interposition.
  • Only 17% of patients had no intervening structures between the skin and the gallbladder fundus.
  • The right hemicolon interposed between the gallbladder fundus and skin in 13% of cases.

Conclusions:

  • The majority of patients require a transhepatic approach for percutaneous cholecystostomy due to anatomical barriers.
  • Understanding these anatomical variations is essential for planning percutaneous gallbladder interventions.
