Endoscopiques

Endoscopiques denotes procedures and techniques that employ an endoscope to visualize the interior surfaces of the body. Endoscopy is used both diagnostically and therapeutically, enabling direct inspection, targeted biopsies, and a range of interventions without open surgery. Endoscopic equipment can access the gastrointestinal tract, respiratory tract, urinary tract, biliary system, and other hollow or lined structures through natural orifices or small incisions.

Common procedures include gastroscopy (esophagogastroduodenoscopy), colonoscopy, bronchoscopy, cystoscopy, and endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic ultrasound (EUS) combines endoscopy with ultrasonography for imaging and sampling near the gastrointestinal tract. Capsule endoscopy uses a swallowed camera to image the small intestine. Enteroscopy extends visualization of the small intestine beyond the reach of standard endoscopy.

Endoscopes are slender instruments with a light source and camera, designed to be flexible or rigid. Many devices include channels for accessories such as biopsy forceps, snare polypectomy tools, dilators, stents, and drainage catheters. Modern systems integrate video imaging, high-definition displays, and, in some cases, ultrasound, fluoroscopy, or therapeutic instruments that enable targeted interventions during a single session.

Before an endoscopic procedure, clinicians assess medical history and risks, obtain informed consent, and arrange appropriate sedation or anesthesia. Procedures are performed under sterile conditions, with monitoring for complications. Post-procedure recovery varies by type and patient vulnerability.

Endoscopy is performed by specialists such as gastroenterologists, pulmonologists, urologists, and interventional radiologists, often in dedicated suites or hospitals. Training emphasizes patient selection, technique, safety, and management of potential complications, guided by professional societies and clinical guidelines.
