In Japan, colorectal endoscopic submucosal dissection (ESD) is being conducted safely and effectively as shown by the increased number of the cases, however, it is still regarded as a complicated and challenging procedure. Therefore, piecemeal endoscopic mucosal resection (p-EMR) is still regarded as an appropriate treatment, rather than ESD for large colorectal tumors, especially in Western countries. Areas covered: There are several factors that are responsible for colorectal ESD difficulty. Firstly, there is no adequate traction or counter-traction in colorectal ESD...

Concomitant gastric stromal tumor (GST) and gastric cancer (GC) is uncommon; even more uncommon is a concomitant GST and early stage GC (EGC). Tumor resection by endoscopic submucosal dissection (ESD) for concomitant GST and EGC has not been reported. We sought to define the clinical importance of detection of concomitant GST and EGC during the first esophagogastroduodenoscopy (EGD), and compare the clinical outcomes of ESD versus radical surgery for the treatment of concomitant GST and EGC. Our investigation was a retrospective cohort study...

BACKGROUND AND AIMS: Early esophageal squamous cell neoplasia (ESCN) can be successfully treated by endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), or radiofrequency ablation (RFA). A new portable, battery-powered cryotherapy system using nitrous oxide (cryoballoon focal ablation system (CbFAS) has been used for Barrett's esophagus. It consists of a small hand-held device containing liquid nitrous oxide, which converts to gas within a low-pressure-compliant through-the-scope balloon and freezes targeted mucosa in contact with the balloon...

BACKGROUND AND AIMS: Endoscopic resection of extensive esophageal lesions has become more common as endoscopic resection techniques and equipment has developed. However, extensive esophageal endoscopic resections can cause postoperative esophageal strictures, which have a negative impact on the quality of life of patients. We aimed to review current treatments and innovative approaches to prevent esophageal strictures after widespread endoscopic resection of esophageal lesions. METHODS: We performed a comprehensive literature search using predetermined search terms from 2000 to 2016 to identify relevant articles and summarized their results as a narrative review...

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...

PURPOSE OF REVIEW: Most of small tumours in gastrointestinal tract are easily removed by endoscopic mucosal resection (EMR). However, EMR are sometimes not reliable to ensure the complete resection for large tumours. Although endoscopic submucosal dissection (ESD) was developed, it had a higher risk for complications such as perforation and bleeding. The techniques and clinical outcomes of EMR and ESD are reviewed. RECENT FINDINGS: ESD is more effective for early gastric and oesophageal cancer with higher en-bloc resection rate and lower local recurrence in comparison to EMR...

BACKGROUND AND STUDY AIMS : Patients receiving antithrombotic drugs have a higher risk of postoperative bleeding and thromboembolic events related to endoscopic procedures. The aim of this study was to evaluate the relationship between various antithrombotic therapies and bleeding after gastric endoscopic submucosal dissection (ESD) (post-ESD bleeding). PATIENTS AND METHODS:  Among 529 consecutive gastric ESD procedures (483 patients with 579 legions), 100 patients with 121 lesions who underwent 108 procedures were on antithrombotic therapy (group A) and 382 patients with 458 lesions who underwent 421 procedures were not on antithrombotic therapy (group B)...

BACKGROUND: Although endoscopic submucosal tunnel dissection has been used for the resection of esophageal and stomach neoplastic lesions, there are still no reports about large superficial rectal neoplastic lesions. Compared with esophageal and stomach endoscopic submucosal dissection, the dissection of large superficial rectal neoplastic lesions is more difficult because of the flimsy bowel wall with abundant vasculature in the submucosal region, which results in poor endoscopic maneuverability and serious complications, such as bleeding and perforation...

The role of nodal station No. 14v (along the superior mesenteric vein) in lymphadenectomy for distal gastric cancer remains elusive. A 73-year-old woman underwent endoscopic submucosal dissection for gastric cancer, and was referred to our division for additional surgery because of pathologically non-curative resection. A laparoscopic distal gastrectomy with D1+ dissection was performed, with a final diagnosis of pT1bN1M0, Stage IB (2 nodal metastases to No. 6). Four months post-surgery, abdominal computed tomography revealed a 14-mm solitary nodule along the superior mesenteric vein...

Minimally invasive surgical interventions in the gastrointestinal tract, such as Endoscopic Submucosal Dissection (ESD), are very difficult for surgeons when performed with standard flexible endoscopes. Robotic flexible systems have been identified as a solution to improve manipulation. However, only a few such systems have been brought to preclinical trials as of now. As a result, novel robotic tools are required.

REVIEW
Toshihiro Nishizawa, Naohisa Yahagi
Endoscopic submucosal dissection (ESD) is becoming the main procedure for the resection of early gastric cancer (EGC). The absolute indications for treating EGC with endoscopic resection were established by the Japanese Gastric Cancer Association and have been generally accepted. However, the absolute indications for treating EGC are rather strict, and expanded indications have been developed. Many studies have reported favorable long-term outcomes for patients who received curative resection for the expanded indication...

This study was designed to investigate the efficacy and safety of endoscopic submucosal dissection (ESD) for treatment of early gastric cancer. In this study, we evaluated the effects of antithrombotic drugs on bleeding risk in patients with ESD. Meta analysis showed that the use of antithrombotic drugs before ESD can reduce the risk of postoperative bleeding, but the early recovery of the use of antithrombotic drugs, or combined with a variety of antithrombotic drugs will increase the risk of bleeding. Twenty-four lesions in 524 patients were treated using ESD, and treatment status and efficacy were observed...
