Abstract
OBJECTIVES Long-term outcomes of gastric subepithelial lesions have not been elucidated. To reveal the natural history, we initiated a prospective, 10-year follow-up of patients with small (≤20 mm) gastric subepithelial lesions in September 2014. Here, we report the results of an interim analysis of a prospective observational study. METHODS In total, 567 patients with 610 lesions were prospectively registered between September 2014 and August 2016. The location, size, morphology, and number of subepithelial lesions were recorded on a web-based case report form. This study has been conducted as an Academic Committee Working Group of the Japan Gastroenterological Endoscopy Society. RESULTS The endoscopic follow-up period was 4.60 ± 1.73 years (mean ± standard deviation), and survival data were investigated for 5.28 ± 1.68 years. This interim analysis revealed that the estimated cumulative incidence of a size increase ≥5 mm, after accounting for patients' death and resection of the tumor as competing risk events, was 4.5% at 5 years. In addition, the estimated cumulative incidence of lesion size increase ≥5 mm or resection of lesions was 7.9% at 5 years, and that of size increase ≥10 mm or resection of lesions was 4.5% at 5 years. CONCLUSION These results indicate that approximately one in 13 patients with small (≤20 mm) gastric subepithelial lesions may require resection or further investigation for increased tumor size (≥5 mm) within 5 years.

Abstract
BACKGROUND/AIMS For duodenal subepithelial lesions showing a hypoechoic mass on endoscopic ultrasound imaging, the utility of endoscopic ultrasound-guided fine-needle aspiration and the frequency of histological types have not been the focus of previous literature. This study aimed to clarify this. MATERIALS AND METHODS This prospective observational study enrolled 22 consecutive patients who underwent endoscopic ultrasoundguided fine-needle aspiration for duodenal subepithelial lesions with hypoechoic mass on endoscopic ultrasound. Immunohistochemical analysis was performed for all endoscopic ultrasound-guided fine-needle aspiration and surgically resected specimens. The main outcome measures were the technical results of endoscopic ultrasound-guided fine-needle aspiration and the frequency of histological types of duodenal subepithelial lesions with hypoechoic mass. RESULTS Thirteen fine-needle aspiration specimens were obtained from the duodenal bulb and eight from the descending duodenal region. The puncture was not performed because of intervening vessels in one patient. The diagnostic rate was 81% (95% confidence interval: 58.1-94.6, 17/21 patients). In 12 patients receiving surgical resection (excluding one cancellation of endoscopic ultrasoundguided fine-needle aspiration), the diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration was 75% (95% confidence interval: 42.8-94.5, 9/12 patients). No complications were observed. The histopathological diagnoses included 11 cases of gastrointestinal stromal tumor (50%), 2 cases of leiomyoma (9%), 2 cases of metastatic cancer (9%), 2 cases of benign inconclusive, and 1 case each of carcinoid, malignant lymphoma, leiomyosarcoma, gauzeoma, and aberrant pancreas (4.5% each). The frequency of malignant tumors in the duodenal subepithelial lesions with hypoechoic mass group was 73% (16/22 patients). CONCLUSIONS Endoscopic ultrasound-guided fine-needle aspiration for duodenal subepithelial lesions with hypoechoic mass was safe and accurate. As duodenal subepithelial lesion with hypoechoic mass has a reasonably high possibility of containing malignant tumors, it is desirable to perform endoscopic ultrasound-guided fine-needle aspiration.

Abstract
Endoscopic submucosal dissection (ESD) is a globally accepted minimally invasive therapy for early-stage gastrointestinal tract tumors. Although numerous electrosurgical knives have been developed for ESD, technical difficulties and high complication rates (bleeding and perforation) have limited their use worldwide. The grasping-type scissors forceps [clutch cutter (CC)] is the first forceps-type resection device developed with reference to hemostatic forceps. The aim was to allow easy and safe ESD throughout the gastrointestinal tract, as a biopsy technique, using one device. The CC can grasp the target tissue accurately and pull it away from the underlying muscle layer prior to energizing the tissue, for safe and effective incision and hemostasis during ESD. Reported clinical studies showed that ESD using the CC (ESD-CC) is a safe (perforation rate: 0%-3.6%; delayed bleeding rate: 0%-4.2%), technically efficient (en-bloc resection rate: 88.9%-100%), and single-device method for dissecting early-stage gastrointestinal tract tumors. The ESD-CC technique is simple and easy to learn because it can be completed simply by repeating the grasp, pull, and coagulate and/or incise actions using an electrosurgical current. The reported self-completion rate by non-experts was significantly better with the CC than with conventional knives (61.7% vs 24.5%, respectively; P < 0.001). Furthermore, the CC is used for other endoscopic therapies, such as endoscopic polypectomy for large pedunculated polyps, endoscopic myotomy for Zenker’s diverticulum, endoscopic treatment of buried bumper syndrome, and endoscopic necrosectomy for wall-off pancreatic necrosis. The initial reports using CC for these therapies have shown favorable results. In this review, we describe the structural features of the CC, how to use the instrument, efficacies of ESD-CC, and other unique endoscopic therapies using the CC.

Abstract
Endoscopists are at high risk of allowing transmission of coronavirus disease 2019 (COVID-19) during gastrointestinal endoscopy (GIE) procedures under pandemic conditions. The main avenues of droplet-containing aerosol generated during GIE are the mouth, anus, and endoscopic forceps channel. Although the usefulness of personal protective equipment for preventing COVID-19 dissemination has been well reported, measures to address infected aerosol escaping during endoscopic forceps use have been neglected. Pathogen-contaminated aerosol from the endoscopic forceps channel, leading into the gastrointestinal lumen, has been confirmed and is a highly problematic source of infection. We developed a technique that entails covering the forceps entry/exit hole with a vinyl bag, thereby preventing contamination of the endoscopy room by the infected aerosol that escapes from this hole. The technique can be used in daily clinical endoscopic practice. Furthermore, this shielding technique is useful for all patients who undergo GIE, regardless of the purpose of the procedure such as for making a diagnosis, administering therapy, or in an urgent situation. In this letter, we introduce our novel, easily performed, inexpensive method of infection prevention by disallowing infected aerosol to escape from a COVID-19-infected patient into the air during a procedure that requires the use of endoscopic forceps.

Abstract
With the widespread use of esophagogastroduodenoscopy in recent years, the detection rate of superficial non-ampullary duodenal epithelial tumors (SNADETs) is increasing. Most SNADETs are early-stage adenocarcinoma or benign conditions, including adenoma. Therefore, endoscopic resection is desirable from the perspective of quality of life. However, endoscopic resection for SNADETs has not yet been established. Endoscopic submucosal dissection (ESD) is the most promising method for the treatment of SNADETs, because ESD provides a high rate of en bloc resection and a low rate of recurrence regardless of the tumor size. However, the difficulty of the procedure and a high rate of severe adverse events including perforation and bleeding have become major problems. Various preventive countermeasures for adverse events, such as use of specific devices, endoscope stabilization methods, and endoscopic closure of the post-ESD ulcer using clips, are reported to reduce the risk of the adverse events of ESD for SNADETs. This article reviews and highlights the current state of ESD for SNADETs and new challenges towards safe and effective ESD.

Abstract
BACKGROUND The selection of endoscopic treatments for superficial non-ampullary duodenal epithelial tumors (SNADETs) is controversial.
AIM To compare the efficacy and safety of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) for SNADETs.
METHODS We retrospectively analyzed the data of patients with SNADETs from a database of endoscopic treatment for SNADETs, which included eight hospitals in Fukuoka, Japan, between April 2001 and October 2017. A total of 142 patients with SNADETs treated with EMR or ESD were analyzed. Propensity score matching was performed to adjust for the differences in the patient characteristics between the two groups. We analyzed the treatment outcomes, including the rates of en bloc/complete resection, procedure time, adverse event rate, hospital stay, and local or metastatic recurrence.
RESULTS Twenty-eight pairs of patients were created. The characteristics of patients between the two groups were similar after matching. The EMR group had a significantly shorter procedure time and hospital stay than those of the ESD group [median procedure time (interquartile range): 6 (3-10.75) min vs 87.5 (68.5-136.5) min, P < 0.001, hospital stay: 8 (6-10.75) d vs 11 (8.25-14.75) d, P = 0.006]. Other outcomes were not significantly different between the two groups (en bloc resection rate: 82.1% vs 92.9%, P = 0.42; complete resection rate: 71.4% vs 89.3%, P = 0.18; and adverse event rate: 3.6% vs 17.9%, P = 0.19, local recurrence rate: 3.6% vs 0%, P = 1; metastatic recurrence rate: 0% in both). Only one patient in the ESD group underwent emergency surgery owing to intraoperative perforation.
CONCLUSION EMR has significantly shorter procedure time and hospital stay than ESD, and provides acceptable curability and safety compared to ESD. Accordingly, EMR for SNADETs is associated with lower medical costs.

Abstract
Background and aims The Clutch Cutter (CC) can grasp, pull, coagulate, and incise targeted tissue with the use of electrosurgical current. It was developed as a biopsy technique to reduce the technical difficulty of endoscopic submucosal dissection (ESD) with knives. The aim of this study was to evaluate the efficacy and safety of ESD using the CC (ESD-CC) for early colorectal epithelial neoplasms (ECENs). Methods In this prospective study, we enrolled 437 consecutive patients with a diagnosis of ECEN between January 2009 and January 2018. They all satisfied the Japanese colorectal cancer treatment guidelines for ESD; namely, confirmation by preliminary endoscopy, EUS, and endoscopic biopsy. The CC was used for all steps of ESD (mucosal incision, submucosal dissection, and hemostatic treatment); therapeutic efficacy and safety were assessed. Results The en bloc resection rate was 99.3% (434/437), and the R0 resection rate was 87.0% (380/437). The mean operating time was 88.3 minutes. Perforation occurred in 10 cases (2.3%) and was managed with conservative medical treatment. Post-ESD-CC bleeding occurred in 10 cases (2.3%) and was successfully treated by endoscopic hemostatic treatment. Conclusions ESD-CC is a technically efficient, safe, and easy method for resecting ECEN.

Abstract
Gastrointestinal stromal tumors (GISTs) are the most common malignant subepithelial lesions (SELs) of the gastrointestinal tract. They originate from the interstitial cells of Cajal located within the muscle layer and are characterized by over-expression of the tyrosine kinase receptor KIT. Pathologically, diagnosis of a GIST relies on morphology and immunohistochemistry [KIT and/or discovered on gastrointestinal stromal tumor 1 (DOG1) is generally positive]. The prognosis of this disease is associated with the tumor size and mitotic index. The standard treatment of a GIST without metastasis is surgical resection. A GIST with metastasis is usually only treated by tyrosine kinase inhibitors without radical cure; thus, early diagnosis is the only way to improve its prognosis. However, a GIST is usually detected as a SEL during endoscopy, and many benign and malignant conditions may manifest as SELs. Conventional endoscopic biopsy is difficult for tumors without ulceration. Most SELs have therefore been managed without a histological diagnosis. However, a favorable prognosis of a GIST is associated with early histological diagnosis and R0 resection. Endoscopic ultrasonography (EUS) and EUS-guided fine needle aspiration (EUS-FNA) are critical for an accurate diagnosis of SELs. EUS-FNA is safe and effective in enabling an early histological diagnosis and adequate treatment. This review outlines the current evidence for the diagnosis and management of GISTs, with an emphasis on early management of small SELs.

Abstract
AIM To evaluate the clinical outcome of endoscopic submucosal dissection using the Clutch Cutter (ESDCC) in older patients.
METHODS We reviewed 232 consecutive patients with early gastric cancer who underwent ESDCC between June 2010 and February 2014 at Aso Iizuka Hospital. We divided patients into two groups according to age: Older patients (> 80 years, n = 64) and non-older patients (≤ 80 years, n = 168). We retrospectively compared the prevalence rates of pre-existing comorbidities, anticoagulant therapy, en bloc resection, mean duration of hospitalization, incidence of ESDCC-related complications, change in performance status (PS) before and after ESDCC, and financial cost of admission.
RESULTS The older group comprised 64 patients with a mean age of 84.1 years, and the non-older group comprised 168 patients with a mean age of 69.5 years. Older patients had significantly more pre-existing comorbidities than did non-older patients, specifically heart disease (P < 0.05). The en bloc resection rate in non-older patients was significantly higher than that in older patients (100% vs 95.3%, P = 0.02). There were no significant differences between the older and non-older groups in the incidence of ESDCC-related complications (i.e., postoperative bleeding and perforation) and the post-ESDCC change in PS. There were also no significant differences between the older and non-older groups in the mean duration of hospitalization (11.4 and 10.7 d, respectively) and financial cost of admission (657040 JPY and 574890 JPY, respectively).
CONCLUSION ESDCC has a good clinical outcome in older patients.

Abstract
Background/Aims The ability of endoscopic submucosal dissection (ESD) to resect large early gastric cancers (EGCs) results in the need to treat large artificial gastric ulcers. This study assessed whether the combination therapy of rebamipide plus a proton pump inhibitor (PPI) offered benefits over PPI monotherapy. Methods In this prospective, randomized, multicenter, open-label, and comparative study, patients who had undergone ESD for EGC or gastric adenoma were randomized into groups receiving either rabeprazole monotherapy (10 mg/day, n=64) or a combination of rabeprazole plus rebamipide (300 mg/day, n=66). The Scar stage (S stage) ratio after treatment was compared, and factors independently associated with ulcer healing were identified by using multivariate analyses. Results The S stage rates at 4 and 8 weeks were similar in the two groups, even in the subgroups of patients with large amounts of tissue resected and regardless of CYP2C19 genotype. Independent factors for ulcer healing were circumferential location of the tumor and resected tissue size; the type of treatment did not affect ulcer healing. Conclusions Combination therapy with rebamipide and PPI had limited benefits compared with PPI monotherapy in the treatment of post-ESD gastric ulcer (UMIN Clinical Trials Registry, UMIN000007435).

Abstract
AIM To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) using the clutch cutter (CC) (ESD-CC) for gastric adenoma (GA).
METHODS From June 2007 to August 2015, 122 consecutive patients with histological diagnoses of GA from specimens resected by ESD-CC were enrolled in this prospective study. The CC was used for all ESD steps (marking, mucosal incision, submucosal dissection, and hemostatic treatment), and its therapeutic efficacy and safety were assessed.
RESULTS Both the en-bloc resection rate and the R0 resection rate were 100% (122/122). The mean surgical time was 77.4 min, but the time varied significantly according to tumor size and location. No patients suffered perforation. Post-ESD-CC bleeding occurred in six cases (4.9%) that were successfully resolved by endoscopic hemostatic treatment.
CONCLUSION ESD-CC is a technically efficient, safe, and easy method for resecting GA.

Abstract
AIM To determine the prognostic factors associated with mortality in patients with gastric fundal variceal (GFV) bleeding.
METHODS In total, 42 patients were endoscopically diagnosed with GFV bleeding from January 2000 to March 2014. We retrospectively reviewed the patients' medical records and assessed their history, etiology of liver cirrhosis, disease conditions, treatment options for GFV bleeding, medications administered before and after onset of GFV bleeding, blood test results (hemoglobin, albumin, and bilirubin concentrations), and imaging results (including computed tomography and abdominal ultrasonography). We also assessed the prognostic factors associated with short-term mortality (up to 90 d) and long-term mortality in all patients.
RESULTS Multivariate analysis showed that prophylactic administration of antibiotics was an independent prognostic factor associated with decreases in short-term mortality (OR = 0.08, 95%CI: 0.01-0.52) and long-term mortality (OR = 0.27, 95%CI: 0.08-0.91) in patients with GFV bleeding. In contrast, concurrent hepatocellular carcinoma (HCC) and regular use of proton pump inhibitors (PPI) were independent prognostic factors associated with increases in short-term mortality (HCC: OR = 15.4, 95%CI: 2.08-114.75; PPI: OR = 12.76, 95%CI: 2.13-76.52) and long-term mortality (HCC: OR = 7.89, 95%CI: 1.98-31.58; PPI: OR = 10.91, 95%CI: 2.86-41.65) in patients with GFV bleeding. The long-term overall survival rate was significantly lower in patients who regularly used PPI than in those who did not use PPI (P = 0.0074).
CONCLUSION Administration of antibiotics is associated with decreased short- and long-term mortality, while concurrent HCC and regular PPI administration are associated with increased short- and long-term mortality.

Abstract
Background and study aims Endoscopic snare polypectomy with prophylactic detachable snare of large pedunculated colonic polyps (PCPs) is technically demanding. To facilitate removal of such polyps, we developed endoscopic resection using the Clutch Cutter and a detachable snare (ERCCDS). This study aimed to evaluate the efficacy and safety of the procedure. Patients and methods From April 2010 to July 2015, 14 consecutive patients who had PCPs with head > 10 mm, stalk width > 5 mm, and stalk length > 10 mm were enrolled in this single-center prospective uncontrolled study. They were treated using ERCCDS by a single endoscopist. The efficacy and safety were assessed using a database prospectively formatted from the medical records. Results The Clutch Cutter was able to cut the distal side of the stalk an adequate distance from the detachable snare under good visual control. R0 resections were obtained in all lesions. There were no immediate or delayed complications. Conclusions ERCCDS appears to be a safe, easy, and technically efficient method for large PCPs, although larger studies are needed to compare ERCCDS and standard resection.

Abstract
OBJECTIVE Although the World Health Organisation (WHO) defined a novel classification of gastroenteropancreatic neuroendocrine tumours (NETs) in 2010, indications for endoscopic resection of rectal NETs in the guidelines were based on evidence accumulated for carcinoid tumours defined by a previous classification. This study was designed to clarify indications for endoscopic resection of rectal NETs corresponding to the new WHO classifications. MATERIAL AND METHODS One hundred-seventy rectal NETs resected endoscopically from April 2001 to March 2012 were histologically re-classified according to the WHO 2010 criteria. The clinicopathological features of these lesions were analysed, and the short- and long-term outcomes of endoscopic resection were evaluated. RESULTS Of the 170 rectal NETs, 166 were histopathologically diagnosed as NET G1 and four as NET G2. Thirty-eight tumours (22.4%) were positive for lymphovascular invasion, a percentage higher than expected. Although the curative resection rate was low (65.3%), en bloc (98.8%) and complete (85.9%) resection rates were high. Modified endoscopic mucosal resection (88.0%) and endoscopic submucosal dissection (92.2%) resulted in significantly higher complete resection rates than conventional endoscopic mucosal resection (36.4%). No patient experienced tumour recurrence, despite the low curative resection rate. CONCLUSION Despite the low curative resection rate, prognosis after endoscopic resection of rectal NETs was excellent. Prospective large-scale, long-term studies are required to determine whether NET G2 and tumours >1 cm should be included in the indication for endoscopic resection and whether tumours with lymphovascular invasion can be followed up without additional surgery.

Abstract
BACKGROUND AND STUDY AIMS The Clutch Cutter (CC) was developed to reduce the risk of complications related to endoscopic submucosal dissection (ESD) using knives. The CC is able to grasp and coagulate and/or incise the targeted tissue using electrosurgical current, like a biopsy technique. The aim of this study was to evaluate the efficacy and safety of ESD using the CC (ESD-CC) for early gastric cancer (EGC). PATIENTS AND METHODS From June 2007 to March 2014, 325 consecutive patients with a diagnosis of EGC were enrolled in this prospective study. They had all satisfied the Japanese gastric cancer treatment guidelines for ESD indication, namely confirmation by preliminary endoscopy, endoscopic ultrasound, and endoscopic biopsies. The CC was used for all steps of ESD (marking, circumferential marginal incision, submucosal dissection, and hemostatic treatment). The therapeutic efficacy and safety were assessed. RESULTS The en-bloc resection rate was 99.7 % (324/325) and the R0 resection rate was 95.3 % (310/325). The mean operating time was 97.2 minutes. Perforation during ESD-CC occurred in one case (0.3 %), which was managed with conservative medical treatment after endoscopic closure of the perforation. Post-ESD-CC bleeding occurred in 11 cases (3.4 %), which were successfully treated by endoscopic hemostatic treatment. The R0 resection rate was significantly low in tumors > 20 mm (88.9 %), and in the exclusion indication group (73.7 %). Significant differences were seen in the mean operating time, depending upon tumor size, histologic type, location, and indication criteria. CONCLUSIONS ESD-CC is a technically efficient, safe, and easy method for resecting EGC.

Abstract
BACKGROUND AND AIMS There is no evidence of postoperative metastasis of gastric gastrointestinal stromal tumors (GISTs) smaller than 2 cm. The aim of this study was to evaluate the clinical usefulness of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) for gastric subepithelial lesions (SELs) smaller than 2 cm. PATIENTS AND METHODS Using a prospectively maintained EUS-FNA database, 90 consecutive EUS-FNAs of gastric hypoechoic solid SELs smaller than 2 cm diagnosed by EUS were evaluated retrospectively. The reference standards for the final diagnosis were surgery (n=44) and/or clinical follow-up (n=46) using esophagogastroduodenoscopy (EGD), CT, and/or ultrasonography (US). Additionally, immunophenotyping of specimens obtained by EUS-FNA and surgical resection specimens were compared. RESULTS The diagnostic rate of EUS-FNA for gastric hypoechoic solid SELs smaller than 2 cm was 73% (66/90). Histological diagnosis of EUS-FNA showed 47 (52%) malignant SELs (44 GISTs, 1 glomus tumor, 1 SEL like cancer, and 1 malignant lymphoma), 19 (21%) benign SELs (14 leiomyomas, 4 ectopic pancreas, and 1 neurinoma), and 24 (27%) indeterminate SELs. In 44 surgically resected cases, the diagnostic accuracy of EUS-FNA using immunohistochemical analysis was 98% (43/44). There were no complications. Appropriate management was performed in 65 out of 66 SELs (98%) diagnosed by definitive EUS-FNA. After surgery, there was no recurrence of malignant SELs. CONCLUSIONS EUS-FNA is an accurate and safe method in the pre-therapeutic diagnosis of gastric SELs smaller than 2 cm. EUS-FNA for gastric SELs smaller than 2 cm is a promising way to permit early management of patients with gastric SELs including GIST.

Abstract
We experienced an extremely rare case of gastric hyperplastic polyp with xanthoma. A 73-year-old Japanese man was transferred to our hospital from a referral hospital for further evaluation of a pedunculated gastric polyp and early gastric cancer. Esophagogastroduodenoscopy (EGD) revealed a yellow-whitish pedunculated polyp arising from the anterior wall of the fornix. Magnification narrow-band imaging (NBI) endoscopy revealed extended and tortuous microcapillaries and a swollen interfoveolar pattern on the polyp's surface, but there was no sign of malignancy. Endoscopic ultrasonography (EUS) revealed an irregularity of the first layer and a thickened second layer. The third layer was intact. A hyperechoic area was seen in the thickened second layer. Endoscopic submucosal dissection (ESD) for early carcinoma of the antrum and endoscopic mucosal resection (EMR) for a polyp in the fornix were performed in one session. Histological examination of the specimen of the fornix polyp revealed lengthened, branched and dilatated gastric foveolae and a tight sheet of foamy histiocytes in the stroma. The background mucosa of the polyp was atrophic. The pathologic evidence was gastric hyperplastic polyp with proliferation of xanthoma. The early cancer of the antrum was intramucosal tubular adenocarcinoma and was resected curatively.

Abstract
OBJECTIVE The criteria for endoscopic resection for early gastric cancer include absolute and expanded indications. Consensus already exists for the absolute indications. However, the suitability of the expanded indications must be validated by long-term outcome analyses since such lesions have only recently become resectable with the development of endoscopic submucosal dissection. The aim of this study is to clarify the suitability of the expanded indications for the treatment of early gastric cancer with endoscopic submucosal dissection. MATERIALS AND METHODS The medical records of 1161 patients with early gastric cancers (1332 lesions) treated by endoscopic submucosal dissection and meeting the criteria for absolute or expanded indications without additional treatment with gastrectomy were divided into absolute indication group or expanded indication group. RESULTS Complete resection rates were 96.4% and 93.4% in absolute and expanded indication groups, respectively, with no significant differences between the groups. Delayed bleeding rates were significantly higher in the expanded indication group, whereas all cases were successfully managed conservatively. The 5-year overall survival and recurrence-free rates were 93.7%/99.77% and 90.49%/98.90% in the absolute and the expanded indication groups, respectively, with no significant differences between the groups for either measure. Multivariate analyses revealed that affected horizontal margin and tumor location were independent predictive factors for recurrence. CONCLUSION The expanded indication group showed excellent post-endoscopic submucosal dissection short-term and long-term outcomes compared with the absolute indications group, demonstrating that expanded indications are suitable for endoscopic submucosal dissection for early gastric cancer.

Abstract
BACKGROUND/AIM To evaluate whether surgical intervention was useful in patients undergoing surgery for gastric gastrointestinal stromal tumors (GISTs), for tumors ≤ 20 mm in size. PATIENTS AND METHODS Between August 2002 and July 2014, 138 patients with GIST underwent surgery at our Hospital, including 112 patients with gastric GISTs. The medical records of these patients were retrospectively reviewed. RESULTS Postoperative recurrence was observed in three patients, each having tumors with high mitotic rates and ≥ 21 mm in size. In 89 patients undergoing gastric wedge resection, the incidence of postoperative complications was 10.1%; 5.6% of the patients developed late sequelae, all of which were mild. The group classified as having tumors ≥ 21 mm in size had a higher proportion of elderly patients (p=0.0010), more complications (p=0.0152), and longer hospital stay (p=0.0589). CONCLUSION To prevent recurrence, definitive diagnosis and aggressive resection while the tumor size is 20 mm or less is recommended. However, because some patients also carry surgical risks, sufficient consideration must be given to the needs of individual patients.

Abstract
AIM: To investigate the causes and intraoperative detection of endoscopic retrograde cholangiopancreatography (ERCP)-related perforations to support immediate or early diagnosis.
METHODS: Consecutive patients who underwent ERCP procedures at our hospital between January 2008 and June 2013 were retrospectively enrolled in the study (n = 2674). All procedures had been carried out using digital fluoroscopic assistance with the patient under conscious sedation. For patients showing alterations in the gastrointestinal anatomy, a short-type double balloon enteroscope had been applied. Cases of perforation had been identified by the presence of air in or leakage of contrast medium into the retroperitoneal space, or upon endoscopic detection of an abdominal cavity related to the perforated lumen. For patients with ERCP-related perforations, the data on medical history, endoscopic findings, radiologic findings, diagnostic methods, management, and clinical outcomes were used for descriptive analysis.
RESULTS: Of the 2674 ERCP procedures performed during the 71-mo study period, only six (0.22%) resulted in perforations (male/female, 2/4; median age: 84 years; age range: 57-97 years). The cases included an endoscope-related duodenal perforation, two periampullary perforations related to endoscopic sphincterotomy, two periampullary perforations related to endoscopic papillary balloon dilation, and a periampullary or bile duct perforation secondary to endoscopic instrument trauma. No cases of guidewire-related perforation occurred. The video endoscope system employed in all procedures was only able to immediately detect the endoscope-related perforation; the other five perforation cases were all detected by subsequent digital fluoroscope applied intraoperatively (at a median post-ERCP intervention time of 15 min). Three out of the six total perforation cases, including the single case of endoscope-related duodenal injury, were surgically treated; the remaining three cases were treated with conservative management, including trans-arterial embolization to control the bleeding in one of the cases. All patients recovered without further incident.
CONCLUSION: ERCP-related perforations may be difficult to diagnose by video endoscope and digital fluoroscope detection of retroperitoneal free air or contrast medium leakage can facilitate diagnosis.

Abstract
Endoscopic necrosectomy (EN) for walled-off pancreatic necrosis (WOPN) is less invasive than surgical treatment and has become the first choice for pancreatic abscess. EN is usually carried out with several devices including snares, baskets, and grasping forceps. Occasionally, we have encountered cases in which EN has not been satisfactorily carried out, and there is pressure for further innovation in EN. Here, we describe a case of a large area of WOPN that was successfully treated by EN with endoscopic submucosal dissection and associated techniques, which facilitated removal of necrotic tissues. A 60-year-old man was referred to our hospital for WOPN as a complication of necrotizing pancreatitis. As a result of his complicating conditions including ischemic heart disease, uncontrollable arrhythmia, chronic renal failure, and persistent pleural effusion, he was deemed a poor surgical candidate. Although EN with conventional devices was carried out for five sessions, we could not remove the dense and massive necrotic tissues. At the sixth EN session, the Clutch Cutter device (Fujifilm, Tokyo, Japan) was used to remove the necrotic tissues, without major complications. This is believed to be the first report of EN using the Clutch Cutter for successful treatment of WOPN.

Abstract
BACKGROUND To reduce the risk of complications related to endoscopic submucosal dissection (ESD) using knives, we developed the Clutch Cutter (CC), which can grasp and incise the target tissue similarly to biopsy techniques using an electrosurgical current. The aim of this study was to evaluate the efficacy and safety of ESD using the CC for removal of rectal carcinoid tumours. METHODS Between December 2009 and December 2011, we prospectively enrolled seven patients (seven lesions) on 7 different days. Patients were endoscopically diagnosed with rectal subepithelial lesions (upper rectum, n = 3; lower rectum, n = 4) within the level 3 layer and without lymph node involvement, with the diagnosis confirmed by preliminary endoscopy, endoscopic ultrasound and endoscopic biopsies. ESD using the CC was performed in all cases, and the therapeutic efficacy, safety and tumour recurrence were assessed. RESULTS All lesions were treated easily and safely, and there were no inadvertent incisions. En bloc resection was obtained in all cases, and histologic tumour-free lateral/basal margins were obtained in six of the seven patients. No delayed haemorrhage, perforation or tumour recurrence occurred. CONCLUSION ESD using the CC appears to be an easy, safe and technically efficient method for resecting rectal carcinoid tumour.

Abstract
A glomus tumor of the stomach is rare. It is difficult to diagnose the tumor before surgery by only endoscopic biopsy and radiography, and there is no established method of diagnosis before surgical treatment. Esophagogastroduodenoscopy (EGD) on a 50-year-old Japanese woman revealed a 10 mm submucosal tumor in the anterior wall of the gastric angle. Follow-up EGD revealed an increase in the size of the tumor to 15mm. Endoscopic ultrasonography (EUS) demonstrated a 15mm subepithelial hypoechoic solid tumor with continuity to the proper muscle layer. Histologic diagnosis by endoscopic ultrasonography guided fine needle aspiration (EUS-FNA) was glomus tumor. The tumor was treated by laparoscopic local resection. The histologic diagnosis of the resected tumor was similar to the preoperative EUS-FNA results. EUS-FNA would appear to be an effective histologic test for early diagnosis of gastric glomus tumor.

Abstract
BACKGROUND Double balloon endoscopy (DBE) allows the entire small intestine to be viewed using a combination of antegrade and retrograde approaches. Acute pancreatitis is a serious complication of antegrade DBE with no effective prophylactic treatment currently available. Ulinastatin has been shown to be effective for the prevention of pancreatitis following endoscopic retrograde cholangiopancreatography. We therefore assessed the efficacy of ulinastatin for hyperenzymemia after antegrade DBE. PATIENTS AND METHODS Forty-four patients were enrolled in this prospective, randomized, double-blind, placebo-controlled trial. Patients in the ulinastatin group received 150 000 U ulinastatin by i.v. drip infusion for 2 h from the start of the procedure. Serum concentrations of pancreatic amylase and lipase were measured before and 3 and 18 h after antegrade DBE. RESULTS The study was terminated after interim analysis. Of the 44 patients, 23 were randomized to ulinastatin and 21 to placebo.The groups were similar with regard to sex ratio, age, type of endoscope, insertion time, total procedure time, number of endoscope pull-back procedures, and baseline pancreaticamylase and lipase concentrations. Post-DBE hyperenzymemia was observed in 35.0% and 47.8% of patients in the placebo and ulinastatin groups, respectively. The higher frequency of hyperenzymemia in the ulinastatin group was unexpected, but the difference was not statistically significant. One patient in the placebo group (5.0%) and none in the ulinastatin group experienced acute pancreatitis, but the difference was not statistically significant. CONCLUSION The results of this trial suggest that ulinastatin does not prevent hyperenzymemia following antegrade DBE.

Abstract
Endoscopic submucosal dissection (ESD) is accepted as minimally invasive therapy for early stage digestive tract tumors. It has allowed the achievement of histologically curative en-bloc resection of early stage digestive tract tumors regardless of size, including the resection of previously non-resectable tumors. Although numerous electrosurgical knives have been developed for ESD, technical difficulties and high complication rates (bleeding and perforation) have limited their use worldwide. Furthermore, conventional ESD usually needs several devices for each session. We developed the Clutch Cutter® (CC), which can grasp and incise the targeted tissue using electrosurgical current, to resolve such ESD-related problems. The ESD procedure using the CC is as follows: after marking using the CC and the injection of a solution into the submucosa, the lesion is separated from the surrounding normal mucosa by complete incision around the lesion using the CC. A piece of submucosal tissue is grasped and cut with the CC using electrosurgical current to achieve submucosal exfoliation. Intraoperative bleeding is also treated by the CC. Reported clinical studies showed that ESD using the CC is a safe, simple, easy-to-learn, technically efficient (en-bloc resection rate 100%), and a single-device method for the dissection of early stage digestive tract tumors. This new approach is promising to become the worldwide method of choice for early stage digestive tract tumors because it is technically simple and safe to perform.

Abstract
BACKGROUND AND AIM Endoscopic submucosal dissection (ESD) is now accepted as a minimally invasive treatment for early gastric cancer (EGC). To our knowledge, however, the functional effects of ESD have not been determined in patients with EGC. We therefore investigated whether gastric motility was affected by ESD. METHODS Using the (13) C-octanoic acid breath test, gastric emptying of solid test meals was examined in 26 EGC patients and 18 healthy controls, with EGC patients assayed before and about 2 months after ESD. Based on (13) CO2 breath-excretion curves, the lag-phase time (T(lag) ), half-emptying time (T(1/2) ), and gastric emptying coefficient (GEC) were calculated as indices of gastric emptying. RESULTS In healthy controls, the mean T(lag), T(1/2), and GEC were 85.5 ± 4.9 min, 148.5 ± 8.0 min, and 3.01 ± 0.09 h, respectively. Before ESD, the mean T(lag) , T(1/2), and GEC in the EGC patients were 90.1 ± 5.5 min, 174.7 ± 10.4 min, 2.64 ± 0.08 h, respectively. GEC, but not T(lag) or T(1/2), differed significantly in the two groups, with gastric emptying slower in EGC patients than in controls. Relative to before ESD, the mean T(lag), T(1/2), and GEC in EGC patients after ESD were 109.2% ± 7.8%, 107.9% ± 9.6%, 108.4% ± 4.7%, respectively, indicating that ESD did not significantly affect any of these gastric emptying parameters in EGC patients. CONCLUSION ESD is an effective treatment for EGC both in preserving organs and gastric motility.

Abstract
AIM: To investigate the clinical outcome of double balloon enteroscopy (DBE)-assisted endoscopic retrograde cholangiopancreatography (DB-ERCP) in patients with altered gastrointestinal anatomy.
METHODS: Between September 2006 and April 2011, 47 procedures of DB-ERCP were performed in 28 patients with a Roux-en-Y total gastrectomy (n = 11), Billroth II gastrectomy (n = 15), or Roux-en-Y anastomosis with hepaticojejunostomy (n = 2). DB-ERCP was performed using a short-type DBE combined with several technical innovations such as using an endoscope attachment, marking by submucosal tattooing, selectively applying contrast medium, and CO2 insufflations.
RESULTS: The papilla of Vater or hepaticojejunostomy site was reached in its entirety with a 96% success rate (45/47 procedures). There were no significant differences in the success rate of reaching the blind end with a DBE among Roux-en-Y total gastrectomy (96%), Billroth II reconstruction (94%), or pancreatoduodenectomy (100%), respectively (P = 0.91). The total successful rate of cannulation and contrast enhancement of the target bile duct in patients whom the blind end was reached with a DBE was 40/45 procedures (89%). Again, there were no significant differences in the success rate of cannulation and contrast enhancement of the target bile duct with a DBE among Roux-en-Y total gastrectomy (88 %), Billroth II reconstruction (89%), or pancreatoduodenectomy (100%), respectively (P = 0.67). Treatment was achieved in all 40 procedures (100%) in patients whom the contrast enhancement of the bile duct was successful. Common endoscopic treatments were endoscopic biliary drainage (24 procedures) and extraction of stones (14 procedures). Biliary drainage was done by placement of plastic stents. Stones extraction was done by lithotomy with the mechanical lithotripter followed by extraction with a basket or by the balloon pull-through method. Endoscopic sphincterotomy was performed in 14 procedures with a needle precutting knife using a guidewire. The mean total duration of the procedure was 93.6 ± 6.8 min and the mean time required to reach the papilla was 30.5 ± 3.7 min. The mean time required to reach the papilla tended to be shorter in Billroth II reconstruction (20.9 ± 5.8 min) than that in Roux-en-Y total gastrectomy (37.1 ± 4.9 min) but there was no significant difference (P = 0.09). A major complication occurred in one patient (3.5%); perforation of the long limb in a patient with Billroth II anastomosis.
CONCLUSION: Short-type DBE combined with several technical innovations enabled us to perform ERCP in most patients with altered gastrointestinal anatomy.

Abstract
BACKGROUND/AIMS Antithrombotic/nonsteroidal antiinflammatory drug (NSAID) therapies increase the incidence of upper gastrointestinal bleeding. The features of hemorrhagic peptic ulcer disease in patients receiving antithrombotic/NSAID therapies were investigated. METHODS We investigated the medical records of 485 consecutive patients who underwent esophagogastroduodenoscopy and were diagnosed with hemorrhagic gastroduodenal ulcers. The patients treated with antithrombotic agents/NSAIDs were categorized as the antithrombotic therapy (AT) group (n=213). The patients who were not treated with antithrombotics/NSAIDs were categorized as the control (C) group (n=263). The clinical characteristics were compared between the groups. RESULTS The patients in the AT group were significantly older than those in the C group (p<0.0001). The hemoglobin levels before/without transfusion were significantly lower in the AT group (8.24±2.41 g/dL) than in the C group (9.44±2.95 g/dL) (p<0.0001). After adjusting for age, the difference in the hemoglobin levels between the two groups remained significant (p=0.0334). The transfusion rates were significantly higher in the AT group than in the C group (p=0.0002). However, the outcome of endoscopic hemostasis was similar in the AT and C groups. CONCLUSIONS Patients with hemorrhagic peptic ulcers receiving antithrombotic/NSAID therapies were exposed to a greater risk of severe bleeding that required transfusion but were still treatable by endoscopy.

Abstract
Background/Aims Colonic diverticular bleeding can stop spontaneously or be stopped by endoscopic hemostasis. We analyzed the clinical and colonoscopic features of patients with colonic diverticular bleeding to establish the predictive factors for rebleeding. Methods A total of 111 patients (median age, 72 years) with colonic diverticular bleeding in Aso Iizuka Hospital between April 2007 and July 2010 were enrolled. Age, sex, body mass index (BMI), comorbidity, medication, location of bleeding, colonoscopic findings and hemostatic methods were analyzed retrospectively from the hospital records. Results The most common sites of bleeding were the ascending (39.6%) and sigmoid (29.7%) colon. Overt rebleeding occurred in 30 patients (27.0%). Spontaneous hemostasis was seen in 81 patients (73.0%), and endoscopic hemostatic treatment was performed in 30 patients. The BMI in the patients with colonic diverticular rebleeding was significantly higher than in patients without rebleeding. Colonoscopic findings of actively bleeding or nonbleeding visible vessels in the responsible diverticula were more frequent in the group with rebleeding. Conclusions A higher BMI and colonoscopic findings of actively bleeding or nonbleeding visible vessels can be used as predictive factors for colonic diverticular rebleeding. Patients with such findings should be carefully followed up after hemostasis of the initial colonic diverticular bleeding.

Abstract
Endoscopic submucosal dissection (ESD) is now the most common endoscopic treatment in Japan for intramucosal gastrointestinal neoplasms (non-metastatic). ESD is an invasive endoscopic surgical procedure, requiring extensive knowledge, skill, and specialized equipment. ESD starts with evaluation of the lesion, as accurate assessment of the depth and margin of the lesion is essential. The devices and strategies used in ESD vary, depending on the nature of the lesion. Prior to the procedure, the operator must be knowledgeable about the treatment strategy(ies), the device(s) to use, the electrocautery machine settings, the substances to inject, and other aspects. In addition, the operator must be able to manage complications, should they arise, including immediate recognition of the complication(s) and its treatment. Finally, in case the ESD treatment is not successful, the operator should be prepared to apply alternative treatments. Thus, adequate knowledge and training are essential to successfully perform ESD.

Abstract
We report a rare case of adenocarcinoma arising in a gastric partial diverticulum in the upper portion of the stomach. The lesion had been followed up for approximately 14 years as a gastric submucosal tumor. However, a recent regular check-up revealed mucous material with some neoplastic tissue discharged from the top of the lesion. A surgically resected specimen showed a well-demarcated submucosal lesion identical to a pseudo-diverticulum carrying a distinctive intramucosal minimally invasive adenocarcinoma in part, with surrounding non-neoplastic but hyperplastic mucosal components. Intestinal phenotype, along with gastric foveolar, pyloric gland-type phenotypes, and neoplastic cells with neuroendocrine differentiation, were also identified in the adenocarcinoma. Chronic and persistent irritation within the diverticulum was postulated to be implicated in the carcinogenesis of the lesion, which carried no definite Helicobacter pylori microorganisms. We believe it is crucial not to overlook carcinoma in a diverticulum presenting as a long-standing submucosal tumor.

Abstract
Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate. The shortcomings of this method are the deficiencies of fixing the knife to the target lesion, and of compressing it. These shortcomings can lead to major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (Clutch Cutter®, Fujifilm, Japan) which can grasp and incise the targeted tissue using an electrosurgical current. Esophagogastroduodenoscopy on a 59-year-old Japanese man revealed a 16mm esophageal submucosal nodule with central depression. Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement. The histologic diagnosis of the specimen obtained by biopsy was granular cell tumor. It was safely and accurately resected without unexpected incision by ESD using the CC. No delayed hemorrhage or perforation occurred. Histological examination confirmed that the granular cell tumor was completely excised with negative resection margin.We report herein a case of esophageal granular cell tumor successfully treated by an ESD technique using the CC.

Abstract
BACKGROUND AND STUDY AIMS To compare the clinical outcome of double-balloon colonoscopy (DBC) with conventional colonoscopy (CC) for colon evaluation performed by an unskilled colonoscopist. PATIENTS AND METHODS Between June 2008 and November 2008, 1544 colonoscopies were performed in our hospital. Fifty-eight patients, (29 male and 29 female ; 19-86 years; mean age, 63 years) involving 60 intubations, were enrolled in this study and were assigned randomly to the DBC or CC group. One first-year GI fellow was enrolled and performed these 60 consecutive colonoscopies (30 DBCs, 30 CCs). Completion rate of colonoscopy, cecal intubation time, and rate of analgesic agent usage were analyzed. RESULTS Completion of DBC was 100% (30/30), while completion of CC was 73% (22/30). There was a statistically significant difference (p < 0.05). The mean cecal intubation time was 36.2 +/- 14.4 minutes (DBC) and 36.5 +/- 15.2 minutes (CC). There was no statistically significant difference. Analgesic agent was used with 19 intubations (63%) (DBC) and with 27 intubations (90%) (CC) (p < 0.05). CONCLUSIONS For inexpert endoscopists, using DBC has a higher rate of effectiveness than using CC and can decrease the discomfort of patients during colonoscopic procedures.

Abstract
A 73-year-old woman was referred to our hospital complaining of bloody stool. She had undergone high anterior resection with the double stapling technique for a sigmoid colon cancer 2 years prior to this admission. Colonoscopy revealed a soft submucosal tumor, 4cm in size, on the anal side of the previous anastomosis in the rectum. EUS revealed a cystic lesion located in the third and fourth layers of the rectal wall. EUS-FNA was performed, and the content of the cystic lesion was transparent mucinous liquid. Histologically, the specimen revealed PAS and Alcian blue-positive mucinous material and a small number of inflammatory cells such as foamy macrophages. Therefore, this cystic lesion was diagnosed as a rectal implantation cyst.

Abstract
AIM To reduce the risk of complications related to endoscopic submucosal dissection (ESD) using knives, we developed a new grasping-type scissors forceps (GSF) that can grasp and incise the target tissue using electrosurgical current. The aim of the present study was to evaluate the efficacy and safety of ESD using GSF for the removal of early gastric cancers and adenomas. METHODS ESD using GSF was carried out on 35 consecutive patients with early gastric cancers or adenomas who had preoperative EUS diagnoses of mucosal tumor without lymph node involvement. Therapeutic efficacy and safety were assessed. RESULTS All lesions were treated easily and safely without unexpected incision. The mean size of epithelial tumors and resected specimens was 15.6mm and 32.7mm, respectively. Curative en-bloc resection rates according to tumor size and location were 96% (26/27) in tumors ≤20mm, 100% (8/8) in tumors >20mm, 100% (18/18) of tumors in the lower portion, 100% (8/8) of tumors in the middle portion, 89% (8/9) of tumors in the upper portion, and 97% (34/35) overall. The mean operating time according to tumor size and location was 93.4min in tumors ≤20mm, 140min in tumors >20mm, 77.6min for tumors in the lower portion, 113.4min for tumors in the middle portion, 148.6min for tumors in the upper portion, and 104.1min overall. No intraoperative complication occurred, and postoperative bleeding was seen in 3% (1/35). CONCLUSIONS ESD using GSF allows simple and safe en-bloc resection of early gastric cancer or adenoma irrespective of tumor size and location.

Abstract
AIM Acute haemorrhagic rectal ulcer (AHRU) is characterized by sudden onset of painless and massive rectal bleeding in elderly bedridden patients who have serious illness. Endoscopic diagnosis and management of AHRU is, however, still controversial. We retrospectively investigated 95 AHRU patients to elucidate the clinical characteristics, endoscopic findings and haemostatic strategies. METHOD Between January 1999 and March 2007, 95 patients were diagnosed with AHRU in our hospital. Medical records and colonoscopy files were reviewed. Clinical features, colonoscopic findings, haemostatic treatment and outcome of the patients were evaluated. RESULTS Eighty per cent of the patients were bedridden at the onset. The most frequent underlying disorder was cerebrovascular disease (36.8%). Hypoalbuminaemia (< 3.5 g/dl) was seen in 92.6% of the patients. Endoscopic findings of AHRU were classified as circumferential ulcer (41.1%), linear or nearly round small ulcer(s) (44.2%), circumferential and small ulcer(s) (7.4%) and Dieulafoy-like ulcer (7.4%). Primary endoscopic haemostatic treatment was performed in 45.3% of cases. Recurrent bleeding occurred in 24.2% of patients. Permanent haemostasis was achieved by secondary endoscopic treatment in 82.6% of re-bleeding patients. CONCLUSION Understanding the typical clinical and endoscopic findings and careful endoscopic examination are important for the accurate diagnosis of AHRU, and endoscopic haemostatic therapy may be effective for bleeding patients.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a useful modality when the target is a lymph node located in the mediastinum, perigastric area or perirectum. Although it is difficult to carry out EUS-FNA of the colon using an oblique view linear scope, we report two cases of successful EUS-FNA of the lesions via the proximal sigmoid colon using a recently available new convex type EUS scope. Case 1 was a 77-year-old Japanese woman noted to have multiple lymph node swelling in the para-aortic area and in the pelvis. Case 2 was a 60-year-old Japanese woman noted to have a large mass in the left lower abdomen. In case 1, oral EUS showed no lymph node swelling. In both cases, EUS with forward-viewing radial echoendoscope was carried out via the anus, and multiple lymph-node swelling or a large mass was observed near the proximal sigmoid colon. In the EUS-FNA for these cases, we used a new convex-type EUS scope that has an oblique view, but with a wide-angled optical device giving a view similar to a forward one. EUS-FNA was successfully carried out on the lesions. The pathological specimen revealed diffuse large B-cell lymphoma in case 1 and gastrointestinal stromal tumor (GIST) in case 2.

Abstract
Gastrointestinal stromal tumor (GIST) is one of the most common malignant mesenchymal tumors of the stomach. Prognosis of this disease is related to tumor size and mitotic activity and early diagnosis is the only way to improve it. Diagnosis of GIST always requires histological and immunohistochemical confirmation as no imaging modalities can diagnose it conclusively. Endoscopic forceps biopsy results are frequently negative. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a technique which allows tissue samples to be obtained with minimal risks and is accurate in the diagnosis of GIST. From the point of view of the endoscopist, aggressive use of EUS-FNA is the only promising way to allow early diagnosis and early treatment of this disease.

Abstract
To reduce the risk of complications related to endoscopic submucosal dissection (ESD), we developed a new grasping-type scissors forceps (GSF), which can grasp and incise the targeted tissue using an electrosurgical current. We prospectively evaluated the efficacy and safety of ESD using GSF for the removal of colorectal tumors in 10 consecutive patients. After the submucosa had been injected with a solution, the lesion was separated from the surrounding normal mucosa by complete incision around the lesion using the GSF. A piece of submucosal tissue was grasped and cut with the GSF using an electrosurgical current to achieve submucosal excision. All lesions were treated easily and safely with no unexpected incisions. No delayed hemorrhage or perforation occurred. En bloc resection was obtained in all cases. The tumor-free lateral/basal margins were obtained in eight out of 10 patients. ESD using GSF appears to be an easy, safe, and technically efficient method for resecting early colorectal tumors.

Abstract
BACKGROUND/AIMS Proton pump inhibitor (PPI) therapy is considered as the first choice for treatment of non-erosive reflux disease (NERD). However, NERD is less sensitive to PPIs than erosive gastroesophageal reflux disease (GERD) and the differences between PPIs and H2 receptor antagonists are less evident in NERD than in erosive GERD. Since gastric acid secretion is lower in the Japanese population than in Western populations, we aimed to investigate whether PPI therapy is really necessary for NERD patients in Japan. METHODOLOGY Thirty-three symptomatic endoscopically diagnosed NERD patients were randomly assigned to receive roxatidine acetate 75 mg twice daily (n = 16) or omeprazole 20 mg once daily (n = 17). Gastrointestinal symptoms were assessed using the Gastrointestinal Symptom Rating Scale at baseline and after 4 and 8 weeks of treatment. RESULTS Both roxatidine and omeprazole significantly improved the heartburn score at 4 and 8 weeks. The clinical response rates did not differ between roxatidine and omeprazole. Both roxatidine and omeprazole significantly relieved not only reflux but also abdominal pain and indigestion. The degrees of improvement did not differ between the two groups. CONCLUSION Roxatidine relieved the symptoms of NERD patients with similar effectiveness to omeprazole. Therefore, roxatidine may be a good choice for NERD treatment.

Abstract
Endoscopic submucosal dissection (ESD) has allowed the achievement of histologically curative en bloc resection of gastrointestinal neoplasms regardless of size, permitting the resection of previously non-resectable tumors. The ESD technique for treatment of early gastric cancer has spread rapidly in Japan and a few other Asian countries due to its excellent eradication rate compared to endoscopic mucosal resection. Although numerous electrosurgical knives have been developed for ESD, technical difficulties and high complication rates (bleeding and perforation) have limited their use worldwide. We developed the grasping type scissor forceps (GSF) to resolve such ESD-related problems. Our animal and preliminary clinical studies showed that ESD using GSF is a safe (no intraoperative complication) and technically efficient (curative en bloc resection rate 92%) method for dissection of early gastrointestinal tumors. The use of GSF is a promising option for performing ESD on early stage GI tract tumors both safely and effectively.

Abstract
Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate. The shortcomings of this method are the inability to fix the knife to the target lesion, and compression of the lesion. These can lead to major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (GSF), which can grasp and incise the targeted tissue using electrosurgical current. Colonoscopy on a 55-year-old woman revealed a 10-mm rectal submucosal nodule. The histological diagnosis of the specimen obtained by biopsy was carcinoid tumor. Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement. It was safely and accurately resected without unexpected incision by ESD using a GSF. No delayed hemorrhage or perforation occurred. Histological examination confirmed the carcinoid tumor was completely excised with negative resection margin.
