“…One clinical series comparing a variation of EMRC (known as endoscopic aspiration mucosectomy) with standard EMR for the treatment of early gastric mucosal cancer showed a significant increase in the mean longest diameter of the resected specimen with the EMRC compared with standard EMR biopsy, although there was no comparison of the histological depth of the resected specimen [17]. This series was a retrospective review involving several endoscopists without formal prospective evaluation of the resected specimens [18]. Again, no randomization process was employed and two separate patient groups were compared [18].…”

“…Subsequently, we gradually switched to EAM because the procedure is straightforward and enables the resection of larger specimens than does strip biopsy [4]. However, conventional procedures for EMR such as EAM have a risk of recurrence because of incomplete resection when piecemeal EMR is used to resect larger lesions [8].…”

“…Endoscopic mucosal resection (EMR) was initially performed by strip biopsy [1], followed by the development of techniques such as EMR with a cap-fitted panendoscope (EMRC) [2] and endoscopic aspiration mucosectomy (EAM) [3,4]. In the latter half of the 1990s, techniques for endoscopic submucosal dissection (ESD) were developed and gained popularity [5,6].…”

Background Few studies have compared the outcomes of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) in patients with early gastric cancer. Methods We studied 780 lesions for which endoscopic treatment was indicated according to the Japanese Gastric Cancer Association (JGCA) criteria or the Results The median follow-up was 73 months in the EAM group and 65 months in the ESD group. Overall, the local recurrence rate was significantly lower in the ESD group (0.2 %, 1/421) than in the EAM group (4.2 %, 15/359) (p \ 0.05). For lesions meeting the JGCA criteria, the local recurrence rate was 2.9 % in the EAM group and 0 % in the ESD group (p \ 0.05). For lesions meeting the NCC criteria, the local recurrence rate was 12.5 % in the EAM group and 0.6 % in the ESD group (p \ 0.05). There was no significant difference between the groups in overall survival. Conclusions On long-term follow-up, ESD was associated with a lower rate of local recurrence than EAM for lesions that met the JGCA or the NCC criteria. From the point of view of radical curability, ESD can be recommended for the management of lesions that meet either set of criteria.

“…The lesion is then lifted by forceps and situated into a snare (via the second channel of a dualchannel endoscope), such that the lesion is resected at the base by applying electrocautery [20] . (3) The "cup and suction" or EMR-cap technique is the most frequently used method of EMR in the esophagus [25] . This technique was first described by Inohue et al in 1993 [26] .…”

“…The advantages of the EMR-cap technique are that a standard single-channel endoscope can be used, and only one endoscopy assistant is required. In addition, it appears that there is a lower risk of bleeding compared to the stripoff method [21,25] . The disadvantage is that it may be difficult to ensure that the entire lesion has been aspirated into the cap, and occasionally, visualization of the lesion can be obscured by the cap itself.…”

Endoscopic mucosal resection (EMR) is a technique used to locally excise lesions confined to the mucosa. Its main role is the treatment of advanced dysplasia and early gastrointestinal cancers. EMR was originally described as a therapy for early gastric cancer. Recently its use has expanded as a therapeutic option for ampullary masses, colorectal cancer, and large colorectal polyps. In the Western world, the predominant indication for EMR in the upper gastrointestinal tract is the staging and treatment of advance dysplasia and early neoplasia in Barrett's esophagus. This review will describe the basis, indications, techniques, and complications of EMR, and its role in the management of Barrett's esophagus.
