Digestive and Osteoarticular interventional radiology

In some cases, interventional radiology represents an alternative to conventional surgical treatment, but the two techniques can complement each other. While the principle of conventional surgery is to operate "in the open", i.e. to open up the body and operate with bare hands, interventional radiology makes it possible to operate inside the body without always coming into direct contact with the medical instruments or without visual contact with the organ being operated on. This system therefore saves time and is less invasive for the human body (earning interventional radiology the nickname of "minimally invasive method").

All procedures are preceded by a diagnostic scan or MRI and a pre-intervention consultation with the specialist.

Before any operation, a diagnosis is made on the spot during a pre-intervention consultation, which consists of: 1/ checking that the procedure is indicated. 2/ looking for any contraindications by asking the patient about any allergies and taking a blood sample to check for any blood coagulation problems or any ongoing infectious syndrome. The diagnoses sought by the blood test are : CBC - platelets - prothrombin rate (PT), activated partial thromboplastin time (APTT), sedimentation rate (ESR) and C-reactive protein (CRP). 3/ If the blood sample is taken in one of our laboratories in Guadeloupe, a period of 72 hours is required between the pre-intervention consultation and the operation.

BIOPSY UNDER ECHOGRAPHY OR SCANNER (liver-kidney-retroperitoneum-ganglia)

The ultrasound or CT biopsy procedure involves obtaining a small fragment of tissue (liver or kidney) using a needle. The samples obtained in this way are then analysed in the laboratory using a microscope by a pathologist. In most cases, this procedure enables a diagnosis to be made without the need for surgery.


A thyroid biopsy involves removing fragments of tissue from a thyroid abnormality using a needle through the skin. It is a simple procedure, generally with little or no pain (similar to taking a blood sample), which involves inserting a very fine needle through the skin into the nodule. Several punctures may be necessary to collect enough cells.

Your state of health requires drainage, which consists of placing a flexible tube called a "drain" through the skin to empty what is known as a collection (accumulation of fluid) or an abscess. The positioning of the drain will be guided under radiological control (ultrasound, scanner or radioscopy).


Gallbladder drainage is an operation in which a catheter is inserted through the skin into your liver, and more specifically into your bile ducts. The aim is to drain your bile without the need for surgery. The procedure is performed under ultrasound and X-ray guidance.
