US-guided Trocar Versus Seldiger Technique for Percutaneous Cholecystostomy

Randomized Comparison of US-guided TROcar Versus SELdiger Technique for Percutaneous Cholecystostomy. The TROSELC II Trial.

A single-center randomized comparison of bedside ultrasound (US)-guided trocar technique versus the US-guided Seldinger technique for percutaneous cholecystostomy

This is a single-center, randomized, controlled trial (RCT), comparing bedside US-guided trocar technique versus the US-guided Seldinger technique for percutaneous cholecystostomy (PC). The study will randomize a total of 100 consecutive patients (50 in each group) undergoing PC at one large tertiary university hospital. The primary endpoints will be technical success and procedure-related complication rates. Secondary endpoints will be procedural duration, pain assessment, and clinical success after up to 3 months of follow-up.

Inclusion Criteria:

• All patients requiring PC, regardless of the underlying cause.
• Signed informed consent form

Exclusion Criteria:

• Age <18 years or >100 years
• The necessity for CT-guided PC catheter placement, according to the judgment of the performing physician
• Severe uncontrollable coagulopathy
