Removal of a trapped endoscopic catheter from the gallbladder via percutaneous transhepatic cholecystostomy: technical innovation.

Background: Percutaneous cholecystostomy is used for a variety of clinical problems.

Methods: Percutaneous cholecystostomy was utilized in a novel setting to resolve a problematic endoscopic situation.

Observations: Percutaneous cholecystostomy permitted successful removal of a broken and trapped endoscopic biliary catheter, in addition to helping treat cholecystitis.

Interventional radiology strategies in the treatment of pseudomyxoma peritonei.

Purpose: To describe percutaneous maneuvers to treat the unusual entity symptomatic pseudomyxoma peritonei (PMP).

Methods: Four patients with PMP were treated by interventional radiology techniques that included large catheters (20-30 Fr) alone (n = 3), multiple catheters (n = 4), and dextran sulfate as a catalytic agent through smaller catheters (n = 1). The causes of the PMP were tumors in the ovary (2 patients), appendix (1 patient), and colon (1 patient).

Image-guided 25-gauge needle biopsy for thoracic lesions: diagnostic feasibility and safety.

Purpose: To report our experience regarding the feasibility and safety of 25-gauge needles for biopsy of thoracic lesions.

Materials And Methods: Twenty-six patients with thoracic lesions, predominately pulmonary nodules, measuring 0.7-5.

Salinoma window technique for mediastinal lymph node biopsy.

Computed tomographic-guided transthoracic needle biopsy can access virtually all mediastinal lymph node stations, but is limited by the potential for pneumothorax and bleeding. To avoid these possible complications, the extrapleural "salinoma" technique was used for computed tomographic-guided mediastinal biopsies in 15 patients. Sampling methods were coaxial (8), tandem (5), and single pass (2).

Transosseous access for decompression of an obstructed pelvic kidney.

We report a case of an obstructed pelvic kidney which was decompressed using a transosseous access route. The patient presented with obstructive uropathy and fever, necessitating decompression. Initial access was gained to the kidney by traversing the ilium, allowing subsequent retrograde placement of a double-J ureteric catheter.
