Endoscopic Mucosal Resection Versus Endoscopic Submucosal Dissection for Colorectal Laterally Spreading Lesions. (intERsection)
Endoscopic Mucosal Resection Versus Endoscopic Submucosal Dissection for Laterally Spreading Lesions Non Granular-Flat Elevated Type (LSL-NG-FE) ≥ 20 mm and LSLs-Granular Mixed Type ≥ 30 mm. A Randomized, Non-inferiority Trial.
EMR and ESD are both effective and safe and are associated with a very low risk of procedure related mortality when performed for colorectal laterally spreading lesions (LSL).
Some kind of LSLs have a low risk of submucosal invasive carcinoma (SMIC) or these foci are found in well demarcated areas of the tumor. This is the case of the non-granular flat elevated (LSN-NG-FE) and the LSLs-G mixed subtypes.
The investigators aim to assess if piecemeal EMR (the older technique) for LSLs-G mixed type > 30 mm and LSLs-NG FE type > 20 mm is not inferior to ESD (the new treatment) for the need of additional surgery in the mid-term.

Detailed Description
Endoscopic submucosal dissection (ESD) is curative for lesions with superficial submucosal invasive carcinoma (s-SMIC) and favourable histological features. The procedure is performed mainly for laterally spreading lesions (LSLs) and is the reference treatment for these neoplasms in Asian countries nowadays. LSLs can be granular (G) or non-granular (NG). Most LSLs-G homogenous type are superficial and can be resected by EMR because SMIC is often lacking. On the other hand, since LSLs-G mixed type > 20 - 30 mm have a higher prevalence of SMIC when compared with the homogenous subtype, Asian experts now recommend ESD for this kind of tumors. However, some years ago, EMR had been suggested for LSLs-G mixed type if the largest nodule was resected first and the histological assessment was done separately. The rationale for the latter approach is that the invasive component is usually found within the large nodule.
Conversely, the prevalence of SMIC is higher in LSLs-NG PD type, therefore, ESD is the preferred therapeutic intervention. In addition, LSLs-NG FE type have been associated with multifocal invasion in Japanese studies. However, in Western countries, the percentage of SMIC in LSLs-NG FE type > 20 mm seems much lower than previously described in Asian series. Thus, the investigators do not know if EMR might be enough to remove these tumours.
Furthermore, if the risk of s-SMIC is low, the recurrence rates for ESD in these kind of lesions (LSL-G mixed type > 30 mm and LSL-NG FE type > 20 mm) might be comparable to that of piecemeal EMR, in terms of curative resection (avoiding the need for surgery) in the mid-term. When performing an EMR, recurrences are more frequent, but they are largely inconsequential because it is usually unifocal, diminutive and easily can be managed endoscopically on subsequent sessions.
In order to clarify the controversial issue of performing colorectal ESD in Western countries, the investigators aim to assess if piecemeal EMR (the older technique) for LSLs-G mixed type > 30 mm and LSLs-NG FE type > 20 mm is not inferior to ESD (the new treatment) for the need of additional surgery in the mid-term.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Adults (at least 18 years old).
- LSL-NG FE type ≥ 20mm or LST-G mixed type ≥30mm who have not been previously treated or received submucosal injection, regardless of their location in the colon.
- LSL-NG FE type ≥ 20mm or LST-G mixed type ≥30mm WITHOUT a demarcated area
- The patient must have undergone a complete colonoscopy, reaching the cecum, to detect possible synchronous lesion. If this procedure has not been done previously, it will be performed prior to the inclusion of the patient in the study.
- Patients able to fill in questionnaires written in Spanish or English.
Exclusion Criteria:
- Contra-indication to colonoscopy.
- Contra-indication to general anesthesia.
- Inability to stop antiplatelet agents and anti-coagulant according to the European Society of Gastro-Intestinal Endoscopy guidelines.

Active Comparator: Endoscopic Mucosal Resection (EMR):
Piecemeal EMR is a conventional endoscopic resection technique.
A submucosal injection of a large volume of a solution (normal saline or other) with or without dilute epinephrine (1/10,000) with or without indigo carmine is performed.
Then, sequential piecemeal resection is performed with use of a combination of stiff-type snares.
At the end of the procedure when macroscopically visible adenoma has been totally resected, a snare tip soft coagulation (STSC) of the margin of the scar is performed to eliminate non visible residual neoplastic tissue.
This procedure is quicker and safer than ESD but led to more recurrent disease (around 20% with the standard technique but recently reduced to 5% after the introduction of STSC)
|
Endoscopic mucosal resection (EMR) is an endoscopic resection technique that allows the removal of large colorectal lesions using a conventional "lift-and-cut" procedure or an underwater technique
|
Experimental: : Endoscopic Submucosal Dissection (ESD):
ESD is a newer resection technique that allows en bloc resection for large LSLs.
A submucosal injection is also needed but, in this case, different endo-knives are used to achieve the resection instead of diathermic snares.
The en bloc resection allows a more precise pathological analysis and the risk of recurrence is lower (<2%) when margins are tumor-free.
|
Endoscopic submucosal dissection (ESD) is an endoscopic procedure that allows dissection of larger colorectal lesions in one piece using endoknives. The procedure is technically more difficult, much more time-consuming than EMR, mandates multiday hospital admission and has an increased risk of perforation. |
