Third space endoscopy, also known as submucosal endoscopy, is an innovative technique that allows gastroenterologists to access and visualize deeper layers of the gastrointestinal tract beyond the mucosal surface. This procedure is particularly valuable for evaluating and treating complex GI conditions that involve lesions or abnormalities located within the submucosal layer.

Indications for Third Space Endoscopy

At Sandozi Health, third space endoscopy may be recommended for various indications, including:

• Submucosal Tumors: Evaluation and biopsy of tumors or growths located beneath the mucosal lining of the GI tract.
• Gastric Polyps: Removal or biopsy of polyps that are difficult to access with traditional endoscopy.
• Treatment of Gastrointestinal Bleeding: Hemostasis (control of bleeding) in cases where lesions or vascular abnormalities are located in the deeper layers.
• Management of Achalasia: A condition where the lower esophageal sphincter fails to relax, leading to difficulty swallowing.

Procedure Overview

Before the third space endoscopy procedure:

• Preparation: Patients may need to fast for several hours prior to the procedure, depending on the specific area being examined.
• Anesthesia: Sedation or anesthesia is administered to ensure patient comfort during the procedure.
• Detailed Explanation: Our gastroenterologists provide detailed information about the procedure, its benefits, risks, and expected outcomes.

During the third space endoscopy:

• Endoscope Insertion: A specialized endoscope with capabilities for submucosal dissection or access is used to navigate through the GI tract.
• Submucosal Access: Techniques such as tunneling or lifting the mucosa are employed to access the deeper layers where lesions or abnormalities are located.
• Diagnostic and Therapeutic Interventions: Biopsy samples can be obtained from deeper tissues for pathological analysis. Additionally, treatments such as polypectomy (removal of polyps) or hemostasis can be performed as needed.
