What does it consist of?
The Endoscopic Transmural Resection (ETR) This is an advanced technique that allows for the removal of lesions affecting deeper layers of the digestive tract wall, including the entire wall, through endoscopy and without the need for conventional surgery.
It is used in selected cases where other techniques are insufficient, allowing access to complex lesions and treating them precisely. Thanks to this approach, it is possible avoid more invasive surgical interventions in certain patients.
Its main value is that it offers a minimally invasive alternative for Treat deep injuries, combining diagnostic accuracy and treatment in a single procedure, with a generally faster recovery.
How is the RTME performed?
The Endoscopic Transmural Resection It is an advanced technique that allows lesions to be removed by extracting the entire thickness of the colon wall. The procedure follows these steps:
1. Preparatory steps
Cleaning The patient performs a bowel preparation similar to that for a colonoscopy.
Medication Temporary suspension of antiplatelets or anticoagulants may be required.
Environment It is carried out under General anaesthesia or deep sedation in an operating theatre or a room equipped to ensure the patient's complete relaxation.
2. Technical execution
Capture A plastic cap with a metal clip is usedFTRD-Ovesco) at the tip of the endoscope to capture and pull the lesion inwards.
Sealing and Cutting The clip is fired to close the wall below the lesion, and simultaneously, an electrocautery device cuts the tissue above the clip.
Extraction The lesion is removed in one piece (en bloc) through the anus.
3. Recovery
- Income A minimum income is programmed 24 hours for surveillance.
- Diet The patient starts on a liquid diet for the first few hours after the procedure.
Specific instructions
RTME is indicated for colon injuries of up to 20-25 mm which present technical difficulties:
Intense scarring Residual polyps after failed removal attempts with standard techniques.
Complex locations: Lesions on diverticula or within the appendix.
Early-stage cancer Cases of superficial bowel cancer where it is vital to study the full thickness of the wall to confirm healing.
Submucosal lesions Tumours that grow in the middle layers of the wall.
Recovery and care
Following the intervention, the care protocol within GASTEA Madrid ensure controlled evolution
- Income A minimum income is programmed 24 hours for surveillance.
- Diet The patient will commence a liquid diet during the first few hours following the procedure.
- Evolution Reintegration into normal life is almost immediate after the 24 hours of observation.
- The clip The metallic device is inert, can remain indefinitely and does not restrict travel or medical tests (scans or security arches).
Tracking
Histological analysis: The specimen is fixed and sent for detailed study where the pathologist identifies all layers and the depth of the lesion.
Cure Confirmation The analysis of the margins and depth determines whether the lesion has been removed with curative intent and does not require further surgery.
Monitoring for complications It is recommended to maintain some vigilance at home for possible late symptoms.
Results
- Effectiveness: Initial success in the resection of 92% in our experience.
- Precision: Non-injurious margin rates for 86%.
- AdvantageIt allows for a definitive endoscopic solution in cases that would otherwise require radical surgery.
