Incidence and risk factors for fever after endoscopic submucosal dissection and its derivative technology for gastric lesions. Heliyon 2024; 10:e25748. [PMID: 38384516 PMCID: PMC10878927 DOI: 10.1016/j.heliyon.2024.e25748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 01/28/2024] [Accepted: 02/01/2024] [Indexed: 02/23/2024] Open
Abstract
Introduction Fever is one of the postoperative complications of endoscopic submucosal dissection (ESD) and its derivative technology. However, there are few studies on risk factors for fever after ESD and its derivative technology. The aim of this study was to determine the incidence and related risk factors after ESD and its derivative technology for gastric lesions. Materials and methods A retrospective review of patients with gastric lesions who were treated by ESD and its derivative technology in our hospital from January 2014 to January 2019 was conducted. Results A total of 1955 patients were included in the present study. A total of 451 (23.1 %) patients presented with fever after ESD and its derived techniques. The highest fever temperature was 37.6 ± 3.12 °C, and the number of days with fever was 1.48 ± 0.85. Through single factor and multiple factor analysis, age (OR: 1.261, 95% CI: 1.009-1.576, p < 0.05), procedure time (OR: 1.457, 95% CI: 1.053-2.016, p < 0.05), postoperative gastric tube placement (OR: 2.098, 95% CI: 1:616-2.723, p < 0.05), intraoperative hemorrhage (OR: 1.537, 95% CI: 1.196-1.974, p < 0.05) and perforation (OR: 1.970, 95% CI: 1.531-2.535, p < 0.05) were independent risk factors for postoperative fever. Conclusion Age ≥56 years old, procedure time ≥60 min, gastric tube placement, intraoperative hemorrhage and perforation were independent risk factors for postoperative fever after gastric ESD and its derivative technology. Attention should be given to such patients to minimize the risk of postoperative fever.

Abstract
Background and study aims Gastric cancer (GC) is one of the leading causes of malignancy-related death in Vietnam, with increasing incidence of non-cardia early gastric cancer (N-EGC). Data on accurate diagnosis of EGC and treatment by endoscopic submucosal dissection (ESD) in Vietnam are very sparse. The aim of this study was to describe the characteristics of N-EGC and evaluate the effectiveness and the safety of ESD in Central Vietnam. Patients and methods We prospectively enrolled patients with N-EGC detected by magnified chromoendoscopy from December 2013 to August, 2018 in Central Vietnam. Selected cases of N-EGC received standardized ESD technique and have been following up carefully as in protocol. Results Among 606 GC patients, 46 had N-GEC and underwent ESD. The depth of invasion was pT1a in 33 (71.7 %), pT1b1 in 10 (21.7 %), and pT1b2 in three cases (6.6 %). Mild chronic atrophic gastritis, most being C2 (63 %), and gastritis-like EGC that did not appear malignant was the predominant type. ESD achieved a 97.8 % en bloc resection rate; the mean procedure time was 76 ± 22 minutes (range 24-155), and mean endoscopic tumor size was 23 ± 5 mm (range 13-52) and ESD sample size was 28 ± 7 mm (range 16.5-60). Complications consisted of two patients with bleeding and one with a minor perforation, all of which were successfully managed by endoscopy. The longest and the mean follow-up times were 84 and 64 months, respectively, with no recurrence. Conclusions A significant proportion patients with N-EGC have a background mucosa of mild chronic atrophic gastritis. Our results 7 years after starting ESD demonstrate early promising outcomes with the procedure.

Upper Gastrointestinal Cancer and Liver Cirrhosis. Cancers (Basel) 2022; 14:cancers14092269. [PMID: 35565397 PMCID: PMC9105927 DOI: 10.3390/cancers14092269] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 04/26/2022] [Accepted: 04/29/2022] [Indexed: 02/01/2023] Open
Abstract
Simple Summary There is a higher incidence rate of upper gastrointestinal cancer in those with liver cirrhosis. The contributing factors include gastric ulcers, congestive gastropathy, zinc deficiency, alcohol drinking, tobacco use and gut microbiota. Most of the de novo malignancies that develop after liver transplantation for cirrhotic patients are upper gastrointestinal cancers. The surgical risk of upper gastrointestinal cancers in cirrhotic patients with advanced liver cirrhosis is higher. Abstract The extended scope of upper gastrointestinal cancer can include esophageal cancer, gastric cancer and pancreatic cancer. A higher incidence rate of gastric cancer and esophageal cancer in patients with liver cirrhosis has been reported. It is attributable to four possible causes which exist in cirrhotic patients, including a higher prevalence of gastric ulcers and congestive gastropathy, zinc deficiency, alcohol drinking and tobacco use and coexisting gut microbiota. Helicobacter pylori infection enhances the development of gastric cancer. In addition, Helicobacter pylori, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans also contribute to the development of pancreatic cancer in cirrhotic patients. Cirrhotic patients (especially those with alcoholic liver cirrhosis) who undergo liver transplantation have a higher overall risk of developing de novo malignancies. Most de novo malignancies are upper gastrointestinal malignancies. The prognosis is usually poor. Considering the surgical risk of upper gastrointestinal cancer among those with liver cirrhosis, a radical gastrectomy with D1 or D2 lymph node dissection can be undertaken in Child class A patients. D1 lymph node dissection can be performed in Child class B patients. Endoscopic submucosal dissection for gastric cancer or esophageal cancer can be undertaken safely in selected cirrhotic patients. In Child class C patients, a radical gastrectomy is potentially fatal. Pancreatic radical surgery should be avoided in those with liver cirrhosis with Child class B or a MELD score over 15. The current review focuses on the recent reports on some factors in liver cirrhosis that contribute to the development of upper gastrointestinal cancer. Quitting alcohol drinking and tobacco use is important. How to decrease the risk of the development of gastrointestinal cancer in those with liver cirrhosis remains a challenging problem.

Efficacy of vonoprazan against bleeding from endoscopic submucosal dissection-induced gastric ulcers under antithrombotic medication: A cross-design synthesis of randomized and observational studies. PLoS One 2021; 16:e0261703. [PMID: 34941937 PMCID: PMC8699580 DOI: 10.1371/journal.pone.0261703] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Accepted: 12/09/2021] [Indexed: 12/15/2022] Open
Abstract
Vonoprazan, a potassium-competitive acid blocker, is expected to be superior to proton pump inhibitors (PPIs) in preventing post-endoscopic submucosal dissection (ESD)-induced gastric bleeding. However, the results of randomized controlled trials (RCTs) and observational studies on the efficacy of vonoprazan have been inconsistent. This study aimed to evaluate the effectiveness of vonoprazan in antithrombotic drug users, a population that has been excluded from RCTs. Treatment effects were assessed using cross-design synthesis, which can be adjusted for differences in study design and patient characteristics. We used data from an RCT in Japan (70 patients in the vonoprazan group and 69 in the PPI group) and an observational study (408 patients in the vonoprazan group and 870 in the PPI group). After matching, among the antithrombotic drug users in the observational study, post-ESD bleeding was noted in 8 out of 86 patients in the vonoprazan group and 18 out of 86 patients in the PPI group. After pooling the data from the RCT and observational study, the risk difference for antithrombotic drug users was -14.6% (95% CI: -22.0 to -7.2). CDS analysis suggested that vonoprazan is more effective than PPIs in preventing post-ESD bleeding among patients administered antithrombotic medications.

Abstract
OBJECTIVES Transcatheter arterial embolisation (TAE) is widely used to treat gastrointestinal bleeding. This paper reports the safety and efficacy of TAE for bleeding following endoscopic resection, including endoscopic mucosal resection and endoscopic submucosal dissection. METHODS Fifteen consecutive patients (13 males, two females; mean age 62.2 years) from two tertiary medical centres who underwent TAE for gastroduodenal bleeding after endoscopic resection from November 2001 to December 2020 were included. Patient demographics, clinical presentations, angiographic findings, and TAE details were retrospectively reviewed. RESULTS Immediate bleeding during endoscopic resection was noted in four patients. Delayed bleeding 1-30 days after endoscopic resection in nine patients presented with haematochezia (n = 4), haematemesis (n = 6) and melaena (n = 1). Endoscopic haemostasis was attempted in 11 patients (73.3%) but failed due to continued bleeding despite haemostasis (n = 6), failure to secure endoscopic field (n = 3) and unstable vital signs (n = 2). Eleven patients had positive angiographic findings for bleeding, and all bleeding arteries were embolised except one owing to failed superselection of the bleeder. In the other four patients with negative angiographic findings, the left gastric artery with/without the right gastric artery or the accessory left gastric artery was empirically embolised using gelatin sponge particles. Both technical and clinical success rates were 93.3% (14/15). No procedure-related complications occurred during follow-up. CONCLUSIONS TAE is safe and effective in the treatment of immediate and delayed bleeding after endoscopic resection procedures. ADVANCES IN KNOWLEDGE This is the first and largest 20-year bicentric study published in English on this topic. Empirical TAE for angiographically negative bleeding sites was also effective without significant complications.

Percent reduction of the ulcer size at 4 weeks is a predictor of the complete healing of endoscopic submucosal dissection-induced gastric ulcers. Arab J Gastroenterol 2020; 21:183-188.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) is widely used as a treatment modality for gastric mucosal neoplasia. While proton pump inhibitors (PPIs) have been used for the control of artificial ulcers created by ESD (ESD-ulcers), complete healing of the ulcers is not always achieved in all the cases. The purpose of this study was to identify the clinical factors that are predictive of refractory ESD-ulcers. PATIENTS AND METHODS We recruited 90 patients with 102 artificial ulcers that formed after the patients underwent ESD for gastric tumours. All the patients received a 20-mg capsule of esomeprazole daily until the 56th day after ESD, and underwent endoscopy at 1, 4, 6 and 8 weeks after the ESD. We analyzed the clinical factors that were associated with the complete healing at 8 weeks after the ESD (CH-8w). The ulcers in the scar stage were defined as the complete healing in this study. RESULTS Of the 102 ESD-ulcers, 16.7% failed to show complete healing after the 8 weeks of PPI therapy. Univariate analysis identified the percent reduction of the ulcer size at 4 weeks after ESD (PR-4w) as being significantly associated with CH-8w. Multivariate analysis identified ulcer location in the lower-third of the stomach and PR-4w > 95% as being independently correlated with the CH-8w (odds ratio = 4.86 and 7.89, respectively). Analysis of the area under the receiver operating characteristic (AUROC) curve demonstrated that the AUROC curve of PR-4w for predicting the CH-8w was 0.78. CONCLUSION Based on the results of our study, endoscopic observation at 4 weeks after ESD would help in the early identification of refractory ESD-ulcers.

Abstract
A woman in her 80s underwent endoscopic submucosal dissection (ESD) for a 20-mm-sized early gastric cancer lesion in the posterior wall of the upper gastric body. The lesion was resected en bloc with no adverse events. However, bleeding was observed in a post-ESD mucosal defect the day after ESD, so endoscopic hemostasis was performed. Moreover, hematemesis occurred 4 days after ESD, when the bleeding site showed a sign of pulsatile aneurysm. Therefore, endoscopic hemostasis was considered difficult, and angiographic treatment was chosen. Since angiography revealed a pseudoaneurysm in a portion of a branch of the left gastric artery, embolization with microcoils was performed. Thereafter, no bleeding occurred. To the best of our knowledge, there is no case report about the formation of a pseudoaneurysm in a post-gastric ESD mucosal defect. Thus, this case is being reported to document valuable information.

Abstract
Background: Endoscopic submucosal dissection (ESD) was commonly used for en bloc resection in gastric cancer and adenoma with the risk of delayed bleeding after ESD. We conducted a direct and indirect comparison meta-analysis to evaluate the best choice in preventing post-ESD bleeding among proton pump inhibitors (PPIs), histamine2-receptor antagonists (H2RAs), and the most widely used potassium-competitive acid blocker, vonoprazan. Methods: The Pubmed, Cochrane Library, and Embase were searched for randomized trials. We pooled odds ratios (OR) for preventing post-ESD bleeding using meta-analysis. Results: Sixteen randomized trials met the inclusion criteria including 2,062 patients. Direct comparisons showed slightly significant efficacy in PPIs rather than H2RAs in preventing post-ESD bleeding [OR: 1.83; 95% confidence interval (CI): 1.10 to 3.05] and vonoprazan was better than PPIs (OR: 0.46; 95% CI: 0.25 to 0.86). The adjusted indirect comparison indicated vonoprazan was superior to H2RAs (OR: 0.30, 95% CI: 0.12 to 0.74). In subgroup analysis, PPIs had similar efficacy as H2RAs in 4 weeks, while PPIs were better than H2RAs in 8 weeks’ treatment (OR: 1.91; 95% CI: 1.08 to 3.40). The superiority of vonoprazan than PPIs was more significant in combination therapy (OR: 0.18; 95% CI: 0.04 to 0.69). There was a significant difference in vonoprazan for 8 weeks of medication (OR: 0.44; 95% CI: 0.21 to 0.92). Conclusions: The effects of vonoprazan is better than PPIs than H2RAs in preventing bleeding after ESD. When vonoprazan combined with mucosal protective antiulcer drug in treatment or used in 8 weeks of medication, the efficacy may be even better.

Abstract
BACKGROUND/AIMS Feeding recommendations after endoscopic submucosal dissection (ESD) for gastric neoplasms are not established and based on clinical experience. METHODS This was a prospective pilot randomized controlled trial. Patients undergoing ESD for gastric neoplasms were randomly assigned to solid (n = 50) or liquid diet (n = 50) groups. Beginning the day after hemostasis confirmation until discharge, the solid diet group started on a diet of rice porridge, whereas the liquid diet group started on a liquid diet, with gradual transition to solid food. The primary endpoint was delayed bleeding rate. The secondary endpoints were quality of life (QOL), ulcer-stage, hospital fees, and post-ESD symptoms. RESULTS Delayed bleeding occurred in the solid diet group (2%) but not in the liquid diet group. The QOL evaluation using European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-STO22 showed better score in the solid diet group. The patients who felt dietary restriction at discharge was of a larger number in the liquid diet group (p = 0.019). More patients experienced appetite loss (p = 0.038), constipation (p = 0.022), and dietary restriction (p = 0.037) in the liquid diet group during hospitalization. The other endpoints were equivalent between the groups. CONCLUSION Early initiation of solid foods after ESD is feasible and associated with higher QOL, potentially rendering conventional liquid diets unnecessary, although additional studies are needed (Trial registration number: UMIN000013297).

Abstract
AIM To prospectively investigate the efficacy and safety of clip-flap assisted endoscopic submucosal dissection (ESD) for gastric tumors.
METHODS From May 2015 to October 2016, we enrolled 104 patients with gastric cancer or adenoma scheduled for ESD at Shiga University of Medical Science Hospital. We randomized patients into two subgroups using the minimization method based on location of the tumor (upper, middle or lower third of the stomach), tumor size (< 20 mm or > 20 mm) and ulcer status: ESD using an endoclip (the clip-flap group) and ESD without an endoclip (the conventional group). Therapeutic efficacy (procedure time) and safety (complication: Gastrointestinal bleeding and perforation) were assessed.
RESULTS En bloc resection was performed in all patients. Four patients had delayed bleeding (3.8%) and two had perforation (1.9%). No significant differences in en bloc resection rate (conventional group: 100%, clip flap group: 100%), curative endoscopic resection rate (conventional group: 90.9%, clip flap group: 89.8%, P = 0.85), procedure time (conventional group: 70.8 ± 46.2 min, clip flap group: 74.7 ± 53.3 min, P = 0.69), area of resected specimen (conventional group: 884.6 ± 792.1 mm2, clip flap group: 1006.4 ± 1004.8 mm2, P = 0.49), delayed bleeding rate (conventional group: 5.5%, clip flap group: 2.0%, P = 0.49), or perforation rate (conventional group: 1.8%, clip flap group: 2.0%, P = 0.93) were found between the two groups. Less-experienced endoscopists did not show any differences in procedure time between the two groups.
CONCLUSION For patients with early-stage gastric tumors, the clip-flap method has no advantage in efficacy or safety compared with the conventional method.

Abstract
Cap polyposis is a rare intestinal disorder. Characteristic endoscopic findings are multiple inflammatory polypoid lesions covered by caps of fibrous purulent exudate. Although a specific treatment has not been established, some studies have suggested that eradication therapy for Helicobacter pylori (H. pylori) is effective. We report a case of a 20-year-old man with cap polyposis presenting with hematochezia. Colonoscopy showed the erythematous polyps with white caps from the sigmoid colon to rectum. Histopathological findings revealed elongated, tortuous, branched crypts lined by hyperplastic epithelium with a mild degree of fibromusculosis in the lamina propria. Although H. pylori eradication was instituted, there was no improvement over six months. We then performed en bloc excision of the polyps by endoscopic submucosal dissection (ESD), which resulted in complete resolution of symptoms. ESD may be a treatment option for cap polyposis refractory to conservative treatments. We review the literature concerning treatment for cap polyposis and clinical outcomes.

Abstract
AIM To investigated the relationship between postoperative bleeding following gastric endoscopic submucosal dissection (ESD) and individual antithrombotic agents.
METHODS A total of 2488 gastric neoplasms in 2148 consecutive patients treated between May 2001 and June 2016 were studied. The antithrombotic agents were categorized into antiplatelet agents, anticoagulants, and other antithrombotic agents, and we included combination therapies [e.g., dual antiplatelet therapy (DAPT)]. The risk factors associated with post-ESD bleeding, namely, antithrombotic agents overall, individual antithrombotic agents, withdrawal or continuation of antithrombotic agents, and bleeding onset period (during the first six days or thereafter), were analyzed using univariate and multivariate analyses.
RESULTS The en bloc resection and complete curative resection rates were 99.2% and 91.9%, respectively. Postoperative bleeding occurred in 5.1% cases. Bleeding occurred in 10.3% of the patients administered antithrombotic agents. Being male (P = 0.007), specimen size (P < 0.001), and antithrombotic agent used (P < 0.001) were independent risk factors for postoperative bleeding. Heparin bridging therapy (HBT) (P = 0.002) and DAPT/multidrug combinations (P < 0.001) were independent risk factors associated with postoperative bleeding. The bleeding rate of the antithrombotic agent continuation group was significantly higher than that of the withdrawal group (P < 0.01). Bleeding within postoperative day (POD) 6 was significantly higher in warfarin (P = 0.015), and bleeding after POD 7 was significantly higher in DAPT/multidrug combinations (P = 0.007). No thromboembolic events were reported.
CONCLUSION We must closely monitor patients administered HBT and DAPT/multidrug combinations after gastric ESD, particularly those administered multidrug combinations after discharge.

Abstract
BACKGROUND AND AIM Proton pump inhibitors are effective for the treatment of gastric ulcers after endoscopic submucosal dissection (ESD). However, the most excellent therapy is controversial. Vonoprazan, an active potassium-competitive acid blocker, has a strong gastric acid secretion inhibitory effect, but its efficacy for the treatment of post-ESD gastric ulcers is unclear. Herein, we aimed to determine the healing effect of vonoprazan on post-ESD gastric ulcers. METHODS We carried out a prospective randomized controlled trial examining 92 patients who had undergone ESD for the treatment of gastric neoplasms between April 2015 and June 2016 at Machida Municipal Hospital. Patients were treated with 20 mg/day vonoprazan (V group) or 20 mg/day esomeprazole (E group) for 8 weeks. We evaluated the 8-week cure rate for artificial ulcers and any complications after ESD. RESULTS A total of 80 patients (median age, 73.5 years; 71.3% male) were analyzed. Cure rate for the V group was significantly higher than that for the E group (94.9% [37/39] vs 78.0% [32/41], respectively; P = 0.049). In a multivariate analysis, only vonoprazan was correlated with ulcer healing (odds ratio = 6.33; 95% CI = 1.21-33.20; P = 0.029). Delayed bleeding was experienced only in the E group (7.3% [3/41]), but no significant difference compared with the V group was observed (P = 0.241). CONCLUSION Vonoprazan was significantly superior to esomeprazole for the healing of post-ESD gastric ulcers and should be considered as a treatment of first choice.

Abstract
Background/Aims Endoscopic submucosal dissection (ESD) with air insufflation is commonly used for the staging and treatment of early gastric carcinoma. However, carbon dioxide (CO2) use has been shown to cause less post-procedural pain and fewer adverse events. The objective of this study was to compare the post-procedural pain and adverse events associated with CO2 and air insufflation in ESD. Methods A systematic search was conducted for randomized control trials (RCTs) comparing the two approaches in ESD. The Mantel-Haenszel method was used to analyze the data. The mean difference (MD) and odds ratio (OR) were used for continuous and categorical variables, respectively. Results Four RCTs with a total of 391 patients who underwent ESD were included in our meta-analysis. The difference in maximal post-procedural pain between the two groups was statistically significant (MD, -7.41; 95% confidence interval [CI], -13.6 – -1.21; p=0.020). However, no significant differences were found in the length of procedure, end-tidal CO2, rate of perforation, and postprocedural hemorrhage between the two groups. The incidence of overall adverse events was significantly lower in the CO2 group (OR, 0.51; CI, 0.32–0.84; p=0.007). Conclusions: CO2 insufflation in gastric ESD is associated with less post-operative pain and discomfort, and a lower risk of overall adverse events compared with air insufflation.

Abstract
Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) is a widely accepted and well established procedure because of its curative potential and low invasiveness compared with surgery. Perforation is a potential major complication during ESD, and non-surgical treatments such as endoscopic closure with clips are sufficient in most cases. Here, we report a case of perigastric abscess that occurred as a complication of ESD for EGC. The patient improved with administration of antibiotics without surgical intervention.

Abstract
We investigated the potential of collagen-genipin sols as biomaterials for treating artificial ulcers following endoscopic submucosal dissection. Collagen sol viscosity increased with condensation, allowing retention on tilted ulcers before gelation and resulting in collagen gel deposition on whole ulcers. The 1.44% collagen sols containing genipin as a crosslinker retained sol fluidity at 23°C for >20 min, facilitating endoscopic use. Collagen sols formed gel depositions on artificial ulcers in response to body temperature, and high temperature responsiveness of gelation because of increased neutral phosphate buffer concentration allowed for thick gel deposition on tilted ulcers. Finally, histological observations showed infiltration of gels into submucosal layers. Taken together, the present data show that genipin-induced crosslinking significantly improves the mechanical properties of collagen gels even at low genipin concentrations of 0.2-1 mM, warranting the use of in situ gelling collagen-genipin sols for endoscopic treatments of gastrointestinal ulcers.

Abstract
BACKGROUND Abdominal pain is a common complaint following endoscopic resection (ER). AIMS To investigate the predictive factors for abdominal pain after ER. METHODS Patients who were scheduled to undergo endoscopic mucosal resection or endoscopic submucosal dissection for the treatment of gastric adenoma or cancer were prospectively enrolled. Pain scores were checked every 6 h after ER and whenever patients complained of pain by using a 0-10 pain scale. If the pain score exceeded 5, 25 mg of intravenous (IV) pethidine was administered. RESULTS Among 156 patients who underwent ER, 66 (42.3 %) received IV pethidine due to moderate/severe abdominal pain. Both the number of patients complaining of abdominal pain and the pain scores decreased with time following the procedure, with only a few patients complaining of mild abdominal pain 2 days after ER. Multivariate analysis showed that female sex [odds ratio (OR) 2.88; confidence interval (CI) 1.31-6.33], tumor location in the lower third of the stomach (OR 5.46; CI 2.31-12.92), and procedures time more than 60 min (OR 2.96; CI 1.26-6.98) were significant predictive factors for developing pain after ER. CONCLUSIONS Female sex, tumor location in the lower third of the stomach, and longer procedure time were significantly associated with pain after ER. Close monitoring and active management of pain is recommended for patients who have these risk factors. With these efforts, the majority of patients could experience pain relief within 2 days after the procedure.

Abstract
Background and Aims. Endoscopic submucosal dissection (ESD) outcomes have traditionally been reported from high volume centers in East Asia. Data from low volume centers in other parts of Asia remain sparse. Methods. A retrospective survey with a structured questionnaire of 5 tertiary centers in 3 countries in South East Asia was conducted. Details of training and clinical outcomes of ESD cases, with follow-up data from these centers, were analyzed. Results. Seven endoscopists from the 5 centers performed a total of 35 cases of ESD in the upper gastrointestinal tract (UGIT) over a 6-year duration. Details of the lesions excised were as follows: median size was 20 mm, morphologically 20 (68.6%) were flat/depressed and 6 (17.1%) were submucosal, and histologically 27 (77.1%) were neoplastic. The median duration of ESD procedures was 105 minutes, with an en-bloc resection rate of 91.4%. There was 1 (2.9%) case of delayed bleeding, but no perforation nor mortality in any of the cases. The recurrence rate after ESD was 5.7%. A prolonged ESD duration was influenced by a larger size of lesion (25 mm, p = 0.02) but not by factors related to the training experience of endoscopists. Conclusions. ESD in the UGIT is feasible and safe in low volume centers in Asia.

Acid inhibition exerted by proton pump inhibitors differs by CYP2C19 genotype. Herein, we investigated whether healing speed of artificial ulcers formed after endoscopic submucosal dissection (ESD) was influenced by H. pylori infection, CYP2C19 genotype, or other factors. METHODS A total of 96 H. pylori-positive patients with gastric tumors scheduled for ESD were randomly assigned to receive eradication therapy for H. pylori before ESD (pre-ESD eradication) (n = 44) or after (post-ESD eradication) (n = 52). Patients received eradication therapy consisting of lansoprazole 30 mg, amoxicillin 750 mg, and clarithromycin 200 mg twice daily for 1 week. After ESD, lansoprazole 30 mg was given once daily for 8 weeks. Ulcer size was endoscopically measured on the next day and at 4 and 8 weeks after ESD. RESULTS Mean reduction rate of artificial ulcer area in the pre-ESD eradication group was 94.7% ± 5.5% at 4 weeks, which was similar to that in the post-ESD eradication group (94.7% ± 6.7%, P = 0.987), irrespective of CYP2C19 genotype. In multivariate analyses, location of gastric tumor (middle and upper, odds ratio: 4.05, 95% CI: 1.620-10.230, P = 0.003) was a factor for 97% reduction of artificial ulcer area at 4 weeks post-ESD, but CYP2C19 genotype and H. pylori infection were not. CONCLUSION Healing speed of ESD-induced artificial ulcer was affected by tumor location, but not by time of H. pylori eradication, resected size, or CYP2C19 genotype.

Abstract
BACKGROUND The prevention of bleeding after endoscopic submucosal dissection (ESD) for gastric neoplasms is still an important problem. OBJECTIVE To investigate the efficacy and safety of a shielding method that uses polyglycolic acid (PGA) sheets and fibrin glue to prevent post-ESD bleeding in high-risk patients. DESIGN A nonrandomized trial with historical control subjects. SETTING A single academic hospital in Japan. PATIENTS From July 2013 to February 2014, 45 ESD-induced ulcers in 41 patients with a high risk of bleeding were enrolled in a study group. Forty-one consecutive ESD-induced ulcers in 37 control subjects with a high risk of bleeding were treated in 2013 before the first enrollment. INTERVENTIONS We placed PGA sheets on the mucosal defect and fixed with fibrin glue in the study group. MAIN OUTCOME MEASUREMENTS The post-ESD bleeding rate. RESULTS The post-ESD bleeding occurred at a rate of 6.7% in the study group (3/45 lesions) and 22.0% in the historical control group (9/41 lesions). There was a significant difference in the post-ESD bleeding rate between the 2 groups (P = .041). LIMITATIONS A nonrandomized trial with historical control subjects; a single-center analysis; small sample size. CONCLUSIONS The endoscopic tissue shielding method with PGA sheets and fibrin glue appears to be promising for the prevention of post-ESD bleeding.

Abstract
Endoscopic submucosal dissection (ESD) is a widely accepted treatment for early gastric and esophageal cancer. Compared to endoscopic mucosal resection, ESD has the advantage of enabling en bloc removal of tumors regardless of their size. However, ESD can result in a large artificial ulcer, which may lead to a considerable deformity. Circumferential mucosal defects of more than three-fourths the esophageal circumference, long longitudinal mucosal defects (>30 mm), and lesions in the upper esophagus are significant risk factors for the development of post-ESD strictures of the esophagus. In the stomach, a circumferential mucosal defects more than three-fourths in extent and longitudinal mucosal defects >5 cm are risk factors of post-ESD stricture. If scheduled early, regular endoscopic balloon dilation is effective in controlling and preventing post-ESD stricture. Moreover, intralesional steroid injections or oral steroids can achieve remission of dysphagia or reduce the need for repeated endoscopic balloon dilation. However, further study is needed to improve the prevention of stricture formation.

Abstract
BACKGROUND Carbon dioxide (CO2) insufflation is effective for gastric endoscopic submucosal dissection (ESD). However, its safety is unknown in patients with pulmonary dysfunction. This study aimed to investigate the safety of CO2 insufflation during gastric ESD in patients with pulmonary dysfunction under conscious sedation. METHODS We analyzed 322 consecutive patients undergoing ESD using CO2 insufflation (1.4 L/min) for gastric lesions. Pulmonary dysfunction was defined as a forced expiratory volume in 1.0 s/forced vital capacity (FEV1.0%) <70% or vital capacity <80%. Transcutaneous partial pressure of CO2 (PtcCO2) was recorded before, during, and after ESD. RESULTS In total, 127 patients (39%) had pulmonary dysfunction. There were no significant differences in baseline PtcCO2 before ESD, peak PtcCO2 during ESD, and median PtcCO2 after ESD between the pulmonary dysfunction group and normal group. There was a significant correlation between PtcCO2 elevation from baseline and ESD procedure time (r = 0.22, P < 0.05) only in the pulmonary dysfunction group. In patients with FEV1.0% <60%, the correlation was much stronger (r = 0.39, P < 0.05). Neither the complication incidences nor the hospital stay differed between the two groups. CO2 narcosis or gas embolism was not reported in either group. CONCLUSIONS CO2 insufflation during gastric ESD in patients with pulmonary dysfunction under conscious sedation is safe with regard to complication risk and hospital stay. However, in patients with severe obstructive lung disease, especially in those with FEV1.0% <60%, longer procedure time may induce CO2 retention, thus requiring CO2 monitoring.

Abstract
Endoscopic submucosal dissection (ESD) for early gastric cancer is a well-established procedure with the advantage of resection in an en bloc fashion, regardless of the size, shape, coexisting ulcer, and location of the lesion. However, gastric ESD is a more difficult and meticulous technique, and also requires a longer procedure time, than conventional endoscopic mucosal resection. These factors naturally increase the risk of various complications. The two most common complications accompanying gastric ESD are bleeding and perforation. These complications are known to occur both intraoperatively and postoperatively. However, there are other rare but serious complications related to gastric ESD, including aspiration pneumonia, stenosis, venous thromboembolism, and air embolism. Endoscopists should have sufficient knowledge about such complications and be prepared to deal with them appropriately, as successful management of complications is necessary for the successful completion of the entire ESD procedure.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) is widely used in the resection of gastric tumors en bloc, however, complications such as pyrexia frequently occur following the procedure. The study aim was to elucidate the incidence, clinical characteristics, and risk factors of post-ESD pyrexia. PATIENTS AND METHODS We conducted a retrospective cohort study of 471 consecutive patients with 485 gastric lesions resected by ESD between December 2005 and 2010. Pyrexia was defined as body temperature above 37.5 °C, regardless of its duration. Blood tests and chest radiography were performed three times before and after ESD. Chest and abdominal computed tomography (CT) was taken on postoperative day 1. RESULTS Post-ESD pyrexia developed in 117 patients (24.8 %), including 40 patients with pneumonia as shown by computed tomography. The pyrexia was resolved in all the patients after 1 day (median; range, 1 - 36 days). A multivariate analysis identified age (P = 0.0029) and resection diameter (P = 0.0009) as risk factors for pyrexia in patients without pneumonia, and operation time (P = 0.0025) as a risk factor for pyrexia in patients with pneumonia. CONCLUSION The patient would be at risk for post-ESD pyrexia if a large ESD is performed in the elderly. The longer operation time would raise the risk for pneumonia-associated fever.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) allows en bloc resection of superficial colorectal tumors regardless of size. However, ESD is technically difficult, hazardous, and time consuming. New devices may help overcome these drawbacks. We focused on traction methods and designed a new traction device, the "S-O clip." Its main advantage is that it allows direct visualization of the cutting line during submucosal dissection. Moreover, it can be used at any location without withdrawing the endoscope. The purpose of this study was to evaluate the efficacy and safety of traction device-assisted ESD for large colorectal tumors using the S-O clip. METHODS Between August 2010 and December 2011, ESD was performed in 70 patients with a superficial colorectal tumor ≥20 mm in diameter in our department. Patients were randomized into two groups: 27 cases in the S-O clip-assisted ESD group and 23 cases in the conventional ESD group. Included in the analysis were patient's gender and age, tumor form, size, and location, rate of en bloc resection, procedure time, presence or absence of intraoperative perforation or delayed bleeding, and pathological findings. Subgroup analysis stratified by these factors and multivariate analyses were conducted. RESULTS In the S-O clip-assisted ESD group, all 27 tumors were resected en bloc without any complications. Although a micro perforation occurred in one patient in the conventional ESD group, further surgical treatment was not required. None of the other 22 cases in the conventional ESD group experienced complications. The mean procedure time for the S-O clip-assisted ESD group was significantly shorter than for the conventional ESD group (37.4 ± 32.6 vs. 67.1 ± 44.1 min, p = 0.03). No significant between-group differences were found for the other factors. CONCLUSION Our results demonstrated that S-O clip-assisted ESD is safe and fast for en bloc resection of large superficial colorectal tumors.

Abstract
BACKGROUND The topical antispasmodic agent l-menthol is useful for inhibiting gastric peristalsis during diagnostic upper gastrointestinal endoscopy. However, it remains unclear whether l-menthol is similarly effective during therapeutic endoscopy, thereby improving treatment outcomes in a clinical setting. METHODS A total of 83 patients scheduled to undergo endoscopic treatment at 8 Japanese referral centers were randomly assigned to receive l-menthol or placebo. The degree of gastric peristalsis (peristaltic score: grade 1-5) was assessed by an independent committee. The primary outcome was the proportion of subjects in whom no or mild peristalsis (grade 1 or 2) was maintained throughout endoscopic treatment. Secondary outcomes were the duration of sustained response and the incidence of adverse drug reactions. RESULTS The proportion of patients with no or mild peristalsis was significantly higher in the l-menthol group (85.4 %, 95 % confidence intervals 70.8-94.4: 35/41 subjects) than in the placebo group (39.0 %, 24.2-55: 16/41; P < 0.001). The sustained response rates in the l-menthol and the placebo were, respectively, 90.0 and 39.6 % 30 min post-dose, and 79.9 and 35.7 % at the completion of the resection. The sustained response rates were significantly higher in the l-menthol group than in the placebo group (P < 0.001, log-rank test). The incidence of adverse drug reactions did not differ significantly between the two groups (P = 1.000). CONCLUSIONS During gastric endoscopic submucosal dissection, spraying l-menthol on the gastric mucosa significantly suppressed peristalsis, with minimal adverse drug reactions as compared with placebo. l-menthol solution might be useful for therapeutic endoscopy.

Abstract
AIM: To discuss the clinical value of endoscopic submucosal dissection (ESD) for treating upper gastrointestinal lesions.
METHODS: A total of 52 patients who underwent ESD between May 2012 and May 2013 were retrospectively analyzed to assess the feasibility, safety and efficacy of ESD for treating upper gastrointestinal lesions.
RESULTS: Among 52 patients, 4 had esophageal lesions, 48 had gastric lesions. Postoperative pathology revealed that 40 were mucosal lesions, including esophageal papilloma (n = 2), cardiac hyperplastic polyps (n = 9), cardiac adenoma (n = 3), early gastric cancer (n = 2), high grade intraepithelial neoplasia (n = 3), low grade intraepithelial neoplasia (n = 5), gastric antral adenomatous polyps (n = 9), hyperplastic polyps (n = 5), and intestinal metaplasia (n = 2); and 12 were submucosal lesions, including esophageal leiomyoma (n = 1), esophageal gastrointestinal stromal tumor (n = 1), gastric heterotopic pancreas (n = 7), gastric body gastrointestinal stromal tumor (n = 2), and lipoma (n = 1). All the lesions were completely resected and were confirmed by pathologic examination. No severe bleeding occurred. Perforation occurred in two cases but was safely managed by conservative treatment.
CONCLUSION: ESD is a safe, effective and recommendable treatment for upper gastrointestinal lesions. It can not only resect the lesions completely, but also provide accurate pathologic information.

Abstract
Endoscopic submucosal dissection (ESD) is an accepted standard treatment for early gastric cancer but is not widely used in the esophagus because of technical difficulties. To increase the safety of esophageal ESD, we used a scissors-type device called the stag beetle (SB) knife. The aim of this study was to determine the efficacy and safety of ESD using the SB knife. We performed a single-center retrospective, uncontrolled trial. A total of 38 lesions were excised by ESD from 35 consecutive patients who were retrospectively divided into the following two groups according to the type of knife used to perform ESD: the hook knife (hook group) was used in 20 patients (21 lesions), and the SB knife (SB group) was used in 15 patients (17 lesions). We evaluated and compared the operative time, lesion size, en bloc resection rate, pathological margins free rate, and complication rate in both groups. The operative time was shorter in the SB group (median 70.0 minutes [interquartile range, 47.5-87.0]) than in the hook group (92.0 minutes [interquartile range, 63.0-114.0]) (P = 0.019), and the rate of complications in the SB group was 0% compared with 45.0% in the hook group (P = 0.004). However, the lesion size, en bloc resection rate, and pathological margins free rate did not differ significantly between the two groups. In conclusion, ESD using the SB knife was safer than that using a conventional knife for superficial esophageal neoplasms.

Abstract
BACKGROUND Recently, endoscopic submucosal dissection (ESD) has been performed to treat early gastric cancer. The en bloc resection rate of ESD has been reported to be higher than that of conventional endoscopic mucosal resection (EMR), and ESD can resect larger lesions than EMR. However, ESD displays a higher complication rate than conventional EMR. Therefore, the development of devices that would increase the safety of ESD is desired. Lasers have been extensively studied as a possible alternative to electrosurgical tools. However, laser by itself easily resulted in perforation upon irradiation of the gastrointestinal tract. We hypothesized that performing ESD using a CO2 laser with a submucosal laser absorber could be a safe and simple treatment for early gastric cancer. To provide proof of concept regarding the feasibility of ESD using a CO2 laser with submucosally injected laser absorber solution, an experimental study in ex vivo and in vivo porcine models was performed. METHODS Five endoscopic experimental procedures using a carbon dioxide (CO2) laser were performed in a resected porcine stomach. In addition, three endoscopic experimental procedures using a CO2 laser were performed in living pigs. RESULTS In the ex vivo study, en bloc resections were all achieved without perforation and muscular damage. In addition, histological evaluations could be performed in all of the resected specimens. In the in vivo study, en bloc resections were achieved without perforation and muscular damage, and uncontrollable hemorrhage did not occur during the procedures. CONCLUSIONS Endoscopic submucosal dissection using a CO2 laser with a submucosal laser absorber is a feasible and safe method for the treatment of early gastric cancer.

Abstract
BACKGROUND/AIM Endoscopic treatments of colorectal neoplasms have yet to be standardized. This study aimed to compare efficacy and tolerability of different endoscopic resection methods for colorectal epithelial tumors. METHODS Patients with non-pedunculated colorectal tumors undergoing endoscopic treatments were consecutively enrolled, and their medical records were reviewed retrospectively. The resection methods were classified into three groups: endoscopic mucosal resection with circumferential precutting (EMR-P), endoscopic submucosal dissection with snaring (ESD-S), and endoscopic submucosal dissection alone (ESD). We compared en bloc resection, pathological complete resection, and complications associated with these methods. RESULTS Overall, 206 lesions from 203 patients were included in the study (mean size 25.2 ± 10.1 mm). The number of lesions treated with EMR-P, ESD-S, and ESD was 91 (44.2 %), 57 (27.7 %), and 58 (28.2 %), respectively. There was a significant difference in both the en bloc resection rates (EMR-P, 61.5 %; ESD-S, 64.9 %; ESD, 96.6 %; p = 0.001) and complete resection rates (EMR-P, 51.6 %; ESD-S, 54.4 %; ESD, 75.9 %; p = 0.009). Bleeding and perforation were less frequently observed in the EMR-P group. In the subgroup-analysis of lesions less than 20 mm, however, these differences were not observed. CONCLUSIONS All endoscopic resection methods, including EMR-P, ESD-S, and ESD, were effective and safe for the treatment of colorectal neoplasms. Technically demanding ESD with high en bloc and complete resection rate should be reserved for the suspicious cancer lesion, which requires the precise histological evaluation. EMR-P with good feasibility can be considered an alternative to ESD for the lesions less than 20 mm.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) allows en bloc resection of early neoplastic lesions of gastrointestinal tract. Lesions are lifted by submucosal fluid injection before circumferential incision and dissection. High-pressure fluid injection using water jet (WJ) technology is already used for lifting and dissection in surgery. The study was designed to assess WJ for ESD submucosal lifting and dissection. METHODS An experimental, randomized comparative, "in vivo" nonsurvival animal study on 12 pigs was designed. Stomach mucosal areas were delineated and resected using three ESD techniques: technique A-syringe injection and IT knife dissection; technique B-WJ continuous injection and IT knife dissection; technique C-WJ injection and WJ pulsed dissection. Injection and dissection speeds and complications rates were assessed. RESULTS Water jet continuous injection is faster than syringe injection (B faster than A, p = 0.001 and B nonsignificantly faster than C, p = 0.06). IT knife dissection is significantly faster after WJ continuous injection (B faster than A, p = 0.003). WJ pulsed dissection is significantly slower than IT knife dissection (C slower than A and B, both p < 0.001). The overall procedure speed was significantly higher and the immediate bleedings rate was significantly lower for technique B than A and C (overall procedure speed p = 0.001, immediate bleedings p = 0.032 and 0.038 respectively). There were no perforations with any technique. CONCLUSIONS Water jet fluid continuous injection speeds up ESD, whereas pulsed WJ dissection does not.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) can be technically demanding and requires great attention to detail and prolonged concentration. We assumed that clinical outcomes of ESDs may be affected by cumulative time, and we aimed to compare complete resection rates and adverse events according to cumulative ESD time. METHODS This study involved 1,328 consecutive patients with 1,461 gastric tumors who underwent ESD from January 2008 to July 2011 in a tertiary-care academic medical center. The main outcome measurements were en bloc resection rate, complete resection rate, bleeding rate and perforation rate. RESULTS Patients were divided into three groups according to cumulative time intervals (<2 h vs. 2-4 h vs. ≥ 4 h). Complete resection rate did not differ among the three groups, but early post-ESD bleeding (EPEB) rate was significantly different among the three groups (2.5 vs. 3.5 % vs. 6.6 %, P = 0.040). In multivariate analysis, cumulative time period was an independent predictor of EPEB (2-4 h odds ratio [OR] 2.29, 95 % confidence interval [CI] 1.05-5.01, P = 0.038; ≥ 4 h OR 3.99; 95 % CI, 2.15-7.65, P < 0.001). The rate of perforation was higher in ESDs performed after completing prior endoscopies or outpatient clinic session compared to those performed without prior work (3.8 vs. 1.6 %, P = 0.004). Moreover, prior workload before ESD was an independent predictor of perforation in multivariate analysis (OR 2.77, 95 % CI, 1.37-5.60, P = 0.005). CONCLUSIONS Our data suggest that cumulative ESD time did not influence en bloc or complete resection rate of ESD, but increased the rate of acute bleeding. Moreover, prior workload before ESDs may increase the risk of perforation.

Abstract
OBJECTIVE Epigastric pain management following endoscopic submucosal dissection is an important consideration. This study aimed to investigate the utility and safety of fentanyl patches for pain relief after the procedure. METHODS Patients who were scheduled to undergo endoscopic submucosal dissection were prospectively randomised to either a transdermal fentanyl patch group or a placebo control group. An additional pethidine was intravenously administered when pain developed and a numerical rating scale was used to evaluate both pre- and post-procedural pain. RESULTS One hundred and ten patients were randomly assigned to receive either a 12 mcg/h fentanyl patch or a control patch on the night before the procedure. The fentanyl patch group had significantly lower pain scores immediately following the procedure (mean, 5.17 vs. 4.26, p=0.030). Maximal pain scores during the first 24 h (5.43 vs. 4.46, p=0.038) and pain scores on the day after the procedure (2.98 vs. 1.20, p<0.001) were also lower in the fentanyl patch group. In addition, the fentanyl patch group required a significantly lower dose of pethidine for pain management (24.54 vs. 11.25, p=0.004). CONCLUSIONS The application of a transdermal fentanyl patch is an effective, convenient, and safe method to control epigastric pain after endoscopic submucosal dissection.

Abstract
MicroRNAs (miRNAs) are small noncoding RNAs that function as endogenous silencers of target genes and play critical roles during carcinogenesis. The selective cyclooxygenase-2 (COX-2) inhibitor celecoxib has been highlighted as a potential drug for treatment of gastrointestinal tumors. The aim of this study was to investigate the role of miRNAs in gastric carcinogenesis and the feasibility of a new therapeutic approach for gastric cancer. miRNA expression profiles were examined in 53 gastric tumors including gastric adenomas (atypical epithelia), early gastric cancers and advanced gastric cancers and in gastric cancer cells treated with celecoxib. miRNA microarray analysis revealed that miR-29c was significantly downregulated in gastric cancer tissues relative to nontumor gastric mucosae. miR-29c was significantly activated by celecoxib in gastric cancer cells. Downregulation of miR-29c was associated with progression of gastric cancer and was more prominent in advanced gastric cancers than in gastric adenomas and early gastric cancer. In addition, expression of the oncogene Mcl-1, a target of miR-29c, was significantly increased in gastric cancer tissues relative to nontumor gastric mucosae. Activation of miR-29c by celecoxib induced suppression of Mcl-1 and apoptosis in gastric cancer cells. These results suggest that downregulation of the tumor suppressor miR-29c plays critical roles in the progression of gastric cancer. Selective COX-2 inhibitors may have clinical promise for the treatment of gastric cancer via restoration of miR-29c.

Abstract
Narrow band imaging (NBI) is a new image enhancement system employing optic digital methods to enhance images of blood vessels on mucosal surfaces, allowing improved visualization of mucosal surface structures. Studies have progressed over the last several years, and the clinical usefulness has been demonstrated. NBI has become frequently applied for preoperative diagnosis before endoscopic submucosal dissection (ESD) of digestive tract cancers, as well as for assessment of the range of ESD for en-bloc resection of large lesions. Consensus has been reached with regard to the usefulness of NBI for detecting micro-lesions of esophageal squamous cell carcinoma indicated for ESD, for the diagnosis of the range and depth. NBI has also been attracting attention for diagnosing gastric cancer based on the observation of micro blood vessels on the mucosal surface and mucosal surface microstructures. The usefulness of NBI has been reported in relation to various aspects of colon cancer, including diagnoses of the presence, quality, range, and depth of lesions. However, as NBI has not surpassed diagnostic methods based on magnifying observation combined with the established and widely employed dye method, its role in ESD is limited at present. Although NBI is very useful for the diagnosis of digestive tract cancers, comprehensive endoscopic diagnosis employing the combination of conventional endoscopy including dye spraying, EUS, and NBI may be important and essential for ESD.

Abstract
Although colorectal endoscopic submucosal dissection (ESD) is superior to endoscopic mucosal resection (EMR) in en bloc resection rate, it is technically quite difficult because of the anatomical and histological characteristics of the colorectal wall. This difficulty prevents wide spread of the technique. Establishment of the training system for colorectal ESD is necessary to standardize training and to achieve wider acceptance of this technique. Herein, we describe our training system for colorectal ESD, and assess the validity of the training system for colorectal ESD, based on the clinical outcomes and learning curve of trainees. Our training system for colorectal ESD would help the spread of this procedure.

Abstract
BACKGROUND Hypertonic saline solution (HS) as a submucosal fluid cushion (SFC) for endoscopic submucosal dissection (ESD) has several disadvantages, including a short effect duration and increased risk of bleeding and perforation. Photocrosslinkable chitosan hydrogel in DMEM/F12 medium (PCH) can be converted into an insoluble hydrogel by UV irradiation for 30 seconds. OBJECTIVE To evaluate the feasibility, usefulness, and safety of PCH as an SFC for ESD of esophagi, compared with HS and sodium hyaluronate (SH). DESIGN Survival animal study. SETTINGS Research laboratory study of 24 pig models in vivo. INTERVENTIONS Twenty-four pigs were used in the 2 steps: First, ESD of the esophagus was performed with PCH, SH, or HS (each n = 6) as an SFC, and the effects of these agents on wound healing were examined endoscopically and histologically. Second, in vivo degradation of PCH (n = 3) and HS (n = 3) was examined in independent pig esophagi. MAIN OUTCOME MEASUREMENTS Outcome measurements included feasibility and safety of PCH-assisted ESD of esophagus, gross and histologic evidence of the treated esophagus, biodegradation of injected PCH, and clinical tolerance by the animals. RESULT PCH injection led to a longer-lasting elevation with clearer margins compared with SH and HS, thus enabling precise ESD along the margins of the elevated mucosa without complications such as bleeding and perforation. The aspects of wound repair after PCH-assisted ESD were similar to those of SH- and HS-assisted ESDs. Biodegradation of PCH was confirmed to be almost completed within 8 weeks on the basis of endoscopic and histologic observations. LIMITATIONS In vivo animal model study. CONCLUSION PCH permits more reliable ESD of the esophagus without complications than do SH and HS. Furthermore, the applied PCH appeared to be completely biodegraded within 8 weeks. Thus, PCH is a promising agent as an SFC in ESD of the esophagus.

Abstract
AIM: To investigate risk factors and adverse events related to high-dose diazepam administration during endoscopic submucosal dissection for gastric neoplasias.
METHODS: Between February 2002 and December 2009, a total of 286 patients with gastric epithelial neoplasia underwent endoscopic submucosal dissection in our hospital. To achieve moderate sedation, 5-7.5 mg of diazepam was administered intravenously by non-anesthesiologists. Intermittent additional administration of 2.5-5 mg diazepam was performed if uncontrollable body movement of the patient was observed. All patients were classified into groups based on the required diazepam dose: low-dose (≤ 17.5 mg, n = 252) and high-dose (> 17.5 mg, n = 79).
RESULTS: Differences between the low- and high-dose diazepam groups were observed in lifetime alcohol consumption (0.30 ± 0.48 vs 0.44 ± 0.52 tons, P = 0.032), body weight (58.4 ± 10.3 vs 62.0 ± 9.9 kg, P = 0.006), tumor size (15 ± 10 vs 23 ± 18 mm, P < 0.001), lesion location (P < 0.001) and the presence of ulcerative findings (14/238 vs 18/61, P < 0.001). Multivariate analysis identified all five variables as independently related to required diazepam dosage. In terms of adverse reactions to diazepam administration, paradoxical excitement was significantly more frequent in the high-dose diazepam group (P < 0.001).
CONCLUSION: Intermittent administration of diazepam enabled safe completion of gastric endoscopic submucosal dissection except in patients who were alcohol abusers or obese, or who showed complicated lesions.

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
Endoscopic submucosal dissection (ESD), an endoscopic procedure for the treatment of gastric epithelial neoplasia without lymph node metastases, spread rapidly, primarily in Japan, starting in the late 1990s. ESD enables en bloc resection of lesions that are difficult to resect using conventional endoscopic mucosal resection (EMR). However, in comparison to EMR, ESD requires a high level of endoscopic competence and a longer resection time. Thus, ESD is associated with a higher risk of adverse events, including intraoperative and postoperative bleeding and gastrointestinal perforation. In particular, because of a higher incidence of intraoperative bleeding with mucosal incision and submucosal dissection, which are distinctive endoscopic procedures in ESD, a strategy for endoscopic hemostasis, mainly by thermo-coagulation hemostasis using hemostatic forceps, is important. In addition, because of iatrogenic artificial ulcers that always form after ESD, endoscopic hemostasis and appropriate pharmacotherapy during the healing process are essential.

Abstract
Background/Aims When undergoing endoscopic submucosal dissection (ESD), patients with liver cirrhosis (LC) may suffer from a high risk of bleeding, bacteremia and tissue vulnerability. There have been few reports evaluating the efficacy and safety of ESD in patients with LC. Methods From January 2004 to March 2010, 23 patients with LC (cirrhosis group) underwent ESD for superficial gastric neoplastic lesions. The number of patients with a liver function in the Child-Pugh classes A and B were 20 and 3, respectively. The clinical outcomes and complications were compared with 69 patients without LC (control group) that were matched for age and sex. Results The en bloc resection, R0 resection and en bloc plus R0 resection rates of the cirrhosis group were 82.6%, 91.3%, and 82.6%, respectively, and did not show significant differences from the rates of the control group. No local recurrence was found in either group during the follow-up period. The procedure length of time (41.0 vs 39.0 minutes), rate of bleeding (4.3% vs 7.2%) and rate of perforation (0.0% vs 1.4%) in the cirrhosis group were also comparable to the results from the control group. Conclusions ESD was safely performed in patients with LC, and satisfactory outcomes were achieved with high en bloc and R0 resection rates for superficial gastric neoplastic lesions.

Abstract
Endoscopic submucosal dissection (ESD) is a novel endoscopic procedure first developed in the 1990s which enables en bloc resection of gastric neoplastic lesions that are difficult to resect via conventional endoscopic mucosal resection. However, given that ESD increases the risk of intra- and post-ESD delayed bleeding and that platelet aggregation and coagulation in artificial ulcers after ESD strongly depend on intragastric pH, faster and stronger acid inhibition via proton pump inhibitors (PPIs) and histamine 2-receptor antagonists (H(2)RAs) as well as endoscopic hemostasis by thermocoagulation during ESD have been used to prevent ESD-related bleeding. Because PPIs more potently inhibit acid secretion than H(2)RAs, they are often the first-line drugs employed in ESD treatment. However, acid inhibition after the initial infusion of a PPI is weaker in the early phase than that achievable with H(2)RAs; further, PPI effectiveness can vary depending on genetic differences in CYP2C19. Therefore, optimal acid inhibition may require tailored treatment based on CYP2C19 genotype when ESD is performed, with a concomitant infusion of PPI and H(2)RA possibly most effective for patients with the rapid metabolizer CYP2C19 genotype, while PPI alone may be sufficient for those with the intermediate or poor metabolizer genotypes.

Abstract
BACKGROUND AND AIM Endoscopic submucosal dissection (ESD) enables complete, collective removal of gastrointestinal (GI) malignant tumors, but requires a long operation time. Air insufflated during ESD is distributed throughout the entire GI tract, and thus causes an enlarged feeling of the abdomen. We aimed to reduce the incidence of an enlarged feeling of the abdomen by wedging a balloon in the bulbus duodeni to reduce air flow into the lower parts of the GI tract. METHODS Sixteen patients who were approved by the institutional ethics committee and provided consent to participate in this single-center, prospective study were divided into two groups using a sealed-envelope randomization method: ESD with a balloon wedged in the bulbus duodeni (the balloon [+] group) or conventional ESD with no balloon (the balloon [-] group). Total air volume in the entire GI tract and its change before and after ESD were measured objectively by 3-D computed tomography. RESULTS In the balloon (+) group, the mean intestinal gas volume (± standard deviation) was 274.3 ± 142.0 mL before ESD, and 352.5 ± 183.2 mL after, with a mean change of 78.1 ± 139.7 mL. The increase in intestinal gas volume was well controlled. No postoperative complications, such as an enlarged feeling of the abdomen, was reported in the balloon (+) group. CONCLUSIONS Our new technique has several advantages, including reduction in the frequency of postoperative abdominal symptoms, and will be useful and safe for gastric ESD.

Abstract
Endoscopic submucosal dissection (ESD) is a novel endoscopic treatment that enables a clinician to resect an early-stage gastric cancer in en bloc fashion. ESD is indicated for those cancers in which there is a high probability of en bloc resection and low probability of lymph node metastasis. The latter may be the limiting factor at institutions skilled at ESD. Several ESD techniques are available with similar outcomes. Thus, selection depends on operator preference and expertise. Gastrectomy with lymphadenectomy should be applied initially to those early gastric cancers with high probability of positive lymph nodes or as an additional treatment after ESD. Endoscopic mucosal resection (EMR) should be reserved for small, nonulcerated, intramucosal, differentiated cancers. Disadvantages of ESD in comparison with EMR are longer operation times and higher incidences of intraoperative bleeding and perforation, but the indication for ESD includes larger and ulcerative lesions not amenable to EMR.

Rectal laterally spreading tumors successfully treated in two steps by endoscopic submucosal dissection and endoscopic mucosal resection. BMC Gastroenterol 2010; 10:135.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is an advanced technique of therapeutic endoscopy alternative to endoscopic mucosal resection (EMR) for superficial gastrointestinal neoplasms >2 cm. ESD allows for the direct dissection of the submucosa and large lesions can be resected en bloc. ESD is not limited by resection size, increases histologically complete resection rates and may reduce the local recurrence. Nevertheless, the technique is time-consuming, technically demanding and associated with a high complication rate. To reduce the risk of complications, different devices and technical advances have been proposed with conflicting results and, still, ESD en bloc resections of huge lesions are associated with increased complications. CASE PRESENTATION We successfully used a combined ESD/EMR technique for huge rectal laterally spreading tumors (LSTs). ESD was used for circumferential resection of 2/3 of the lesion followed by piecemeal resection (2-3 pieces) of the central part of the tumour. In all three patients we obtained the complete dissection of the polyp and the complete histological evaluation in absence of complications and recurrence at 6 months' follow up. CONCLUSIONS In the treatment of rectal LSTs, the combined treatment - ESD/EMR resection may be considered a suitable therapeutic option, indicated in selected cases as an alternative to surgery, in which the two techniques are neither reliable nor safe separately. However, to confirm our results, larger trials with longer follow up are required together with improvement of the technique and of the technical devices.

Abstract
BACKGROUND AND AIM Magnifying endoscopy with narrow-band imaging (ME-NBI) enhances images of the irregular mucosal structures and microvessels of gastric carcinoma, and could be useful for determining the margin between cancerous and non-cancerous mucosa. We evaluated the usefulness of ME-NBI for determining the tumor margin compared with indigocarmine chromoendoscopy (ICC). METHODS The subjects were 110 patients (with 118 lesions) who underwent endoscopic submucosal dissection for gastric tumors. They were randomized into ME-NBI and ICC groups. Marking was carried out by electrocautery with the tip of a high-frequency snare at the tumor margins determined by each observation. The distance from the marking dots to the tumor margin was measured histopathologically in the resected specimens. Marking was diagnosed as accurate if the distance was less than 1 mm. RESULTS Of the 118 gastric lesions, 55 were allocated to the ME-NBI group, and 63 to the ICC group. Seventeen lesions in the ME-NBI group and 18 lesions in the ICC group were excluded because the distance from the marking dots to the tumor margin was immeasurable histopathologically. Thirty-eight lesions in the ME-NBI group and 45 lesions in the ICC group were evaluated. The rate of accurate marking of the ME-NBI group was significantly higher than that of the ICC group (97.4% vs 77.8%, respectively; P-value = 0.009). CONCLUSION Magnifying endoscopy with narrow-band imaging can identify gastric tumor margins more clearly than ICC.
