“…Although the ESD is an ideal therapeutic method for every gastrointestinal mucosal lesion indicated for local resection, an easier technique such as EMR using a negative pressure technique would be quite helpful. This necessitates some new devices for ESD such as a useful but complicated endoscope and a special hood including a Vshaped electric knife [13]. These have been designed, but they can be used for only limited purposes.…”

Endoscopic mucosectomy, comprising both endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), is a minimally invasive treatment for patients with early esophageal carcinoma. The use of ESD is appropriate for mucosal lesions of any size. However, ESD techniques are relatively difficult and can lead to serious complications such as perforation and massive bleeding, which have been reported more frequently after ESD than after EMR. This study describes a novel technique for ESD using a newly designed multipurpose treatment hood (TxHood) as well as basic experiments to ensure its safety. The TxHood includes various therapeutic tools such as an electric needleknife, a snare wire, and an injection needle, and the lines can be selected freely before insertion of an enodoscope covered by a TxHood. The main techniques for ESD are endoscopic submucosal saline injections on demand through a working channel of the endoscope or TxHood and a cut or swing cut with a needleknife attached to the TxHood. Moreover, the target area can be grasped with a grasping forceps through a working channel of the endoscope to obtain effective countertraction. In these experiments, an electric needleknife set parallel to the shaft of the endoscope offered safety and ease of handling for the dissecting procedures. Altogether, 16 resections of mucosa with an average size of 3.5 x 2.5 cm (range, 2 x 2 to 7 x 4 cm) were performed. The average time required for each targeted endoscopic resection area was about 15 min. No perforations or instances of uncontrollable bleeding occurred. In conclusion, this basic study demonstrates that the new ESD technique with the TxHood provides a useful treatment for early esophageal carcinoma and may be applicable for all mucosal or submucosal tumors in the gastrointestinal tract.

“…We recently reported the usefulness of three types of original prelooped caps: the irrigating prelooped cap [1], the twochannel prelooped hood [2], and the internally retained snare hood [3] for endoscopic aspiration mucosectomy (EAM). EAM is the simplest method of endoscopic mucosal resection (EMR) [1 -5], but there is a risk of aspirating and perforating the full thickness of the gastric wall.…”

“…The disadvantage of this method, however, is the difficulty in keeping the lesion in the center of the cap, because after aspiration the procedure is performed blindly. Hence, we re− cently reported the usefulness of two types of original irrigating prelooped caps, that is the irri− gating prelooped hood [6] and the two−channel prelooped hood [7]. The irrigating prelooped hood facilitated EMR−C while allowing adequate repeated irrigation of the aspiration site [6 ± 14], and the two−channel prelooped hood facilitated EMRC while simultaneously allowing both irriga− tion of the aspiration site and grasping of the cen− ter of the lesion [7].…”
