“…On the other hand, the PCM method reported in 2014 by Hayashi et al [10] appears to be effective for laterally spreading tumors of the large intestine. Traction is important in ESD but difficult to apply in every situation.…”

“…For endoscopic products, we used an MD-47951 SB soft hood (Sumitomo Bakelite, Tokyo, Japan) and a DualKnife electrosurgical knife (KD-650Q; Olympus). PCM was performed as previously described [9,10]. Briefly, the initial mucosal incision was made after injection of 0.4% sodium hyaluronate solution.…”

“…On the other hand, the pocket creation method (PCM) was reported by Hayashi et al [9,10] as an ESD method for colon tumor, and has been described as a safe technique that offers a high en bloc resection rate compared with conventional colonic ESD [11]. In addition, the characteristics of the procedure make this method useful to ensure pathological evaluation in the vertical direction.…”

Purpose: Pancreatic/gastrointestinal tract neuroendocrine neoplasm (NEN) is divided into neuroendocrine tumor (NET) and neuroendocrine carcinoma (NEC) according to the grade of malignancy, and differences are seen in clinical prognosis. NET, and rectal NET in particular, is often treated endoscopically. Endoscopic mucosal resection (EMR) was previously the main intervention for rectal NET, but EMR with a ligation device (EMR-L) and endoscopic submucosal dissection (ESD) are now also used. However, complete resection with these therapies is not always achieved. The pocket creation method (PCM) is a safe ESD method for colon tumors that offers a high en bloc resection rate compared with conventional colonic ESD. We performed ESD using the PCM for rectal NET and evaluated the complete resection rate. Methods: We performed ESD using the PCM in 4 patients. This procedure was technically feasible in all patients. Results: Endoscopically, all cases were resected en bloc, and pathological complete resection was achieved in all cases. No complications such as perforation or delayed postoperative bleeding were encountered. Conclusions: PCM should be considered when treating NET of appropriate size.

“…The PCM is a new method for cases with severe fibrosis and one of the traction methods ( Figure 7) (30). The specific feature of PCM is the creation of a large submucosal pocket using a long and tapered hood (short ST hood or ST hood: Fujifilm Co., Tokyo, Japan).…”

In Japan, endoscopic submucosal dissection (ESD) becomes one of standard therapies for large colorectal tumors. Recently, the efficacy of ESD has been reported all over the world. However, it is still difficult even for Japanese experts in some situations. Right-sided location, large tumor size, high degree of fibrosis, difficult manipulation is related with the difficulty. However, improvements on ESD devices, suitable strategies, and increase of operators' experiences enable us to solve these problems. In this chapter, we introduce recent topics about various difficult factors of colorectal ESD and the tips such as strategy, devices, injection, and traction method [Pocketcreation method (PCM) etc.].

“…Rectal ESD using the pocket-creation method (PCM) [1] is relatively easy for endoscopists who are used to performing submucosal endoscopy (e. g. peroral endoscopic myotomy [POEM]), even if they have not performed many ESD procedures. Initially, creating the submucosal pocket is similar to the technique for POEM.…”
