“…There are a few reports on use of gastric ESD in children[7-9]. Further, there are a couple of reports showing that ESD is useful for treating anorectal tumors close to the dentate line[10,11]. This procedure is an attractive option for en bloc resection of large sessile or flat colorectal lesions and is associated with very low recurrence rates.…”

Traditional serrated adenoma (TSA) is a type of serrated polyp of the colorectum and is thought to be a precancerous lesion. There are three types of serrated polyps, namely, hyperplastic polyps, sessile serrated adenomas/polyps, and TSAs. TSA is the least common of the three types and accounts for about 5% of serrated polyps. Here we report a pediatric case of TSA that was successfully resected by endoscopic submucosal dissection (ESD). This rare case report describes a pediatric patient with no family history of colonic polyp who was admitted to our hospital with hematochezia. On colonoscopy, we found a polypoid lesion measuring 10 mm in diameter in the lower rectum. We selected ESD as a surgical option for en bloc resection, and histopathological examination revealed TSA. The findings in this case suggest that TSA with precancerous potential can occur in children, and that ESD is useful for treating this lesion.

“…However, ESD increased in Period B compared with Period A. Moreover, Imai et al [26] demonstrated the feasibility of ESD for rectal tumor extending to the dentate line. In our study, 82.4 % of locally recurrent patients in Period A and two of all [12] reported that salvage surgery might be effectiveprimarly in patients with T1 tumors despite the high risk of local recurrence.…”

“…Cases at the dental line are recently reported to be difficult for ESD (26) because there are lots of vessels at the location. However, we manage thick vessels during ESD with the scissor-type knife (Clutch cutter).…”

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.].
