RESUMO
BACKGROUND: Repeat endoscopic submucosal dissection for metachronous recurrence of esophageal squamous cell carcinoma close to previous endoscopic submucosal dissection scars is challenging. Therefore, this study evaluated the efficacy and safety of repeat endoscopic submucosal dissection for recurrent esophageal squamous cell carcinoma. METHODS: The study included 1680 patients. After propensity score matching, esophageal endoscopic submucosal dissection-related outcomes were compared between the post-endoscopic submucosal dissection scar group (n = 91) and first endoscopic submucosal dissection group (n = 910). The Kaplan-Meier method and log-rank tests were used to compare both groups' survival and local recurrence curves. RESULTS: After propensity score matching, the two groups showed no significant difference in en bloc resection rate (97.80% vs. 99.56%, p = 0.096), treatment time (64.75 min vs 61.33 min, p = 0.448), recurrence rate (3.30% vs. 2.20%, p = 0.458), and stricture rate (7.69% vs. 4.07%, p = 0.110). However, the perforation rate was higher in the post-endoscopic submucosal dissection scar group than in the first endoscopic submucosal dissection group (4.40% vs. 1.10%, p = 0.031). The 5-year overall survival rates in the post-endoscopic submucosal dissection scar and first endoscopic submucosal dissection groups were 88.6% and 89.0%, respectively. CONCLUSIONS: Repeated esophageal endoscopic submucosal dissection for recurrent esophageal squamous cell carcinoma yielded satisfactory clinical outcomes and survival rates. Therefore, repeat endoscopic submucosal dissection may effectively treat esophageal squamous cell carcinoma recurrence close to the initial endoscopic submucosal dissection scars.
RESUMO
INTRODUCTION: EndoTrac is a line-attached sheath-type traction device that enables us to control the direction and the force of traction during endoscopic submucosal dissection (ESD). The efficacy of EndoTrac for gastric ESD has not been fully verified. METHODS AND ANALYSIS: The G-Trac study is a multicentre (nine general hospitals and two university hospitals in Japan) collaborative trial assessing the efficacy of EndoTrac for gastric ESDs. Patients with superficial gastric neoplasms will be enrolled and randomly assigned to undergo either conventional ESD or EndoTrac ESD. Allocation will be stratified according to tumour location, operator experience and tumour diameter at an allocation rate of 1:1. The type of endoknife used will be confirmed before randomisation. The primary outcome, procedure time, will be compared between the groups in both intention-to-treat and per-protocol analyses using the Wilcoxon rank sum test. The efficacy-related, safety-related and device-related outcomes will be assessed in the secondary analysis. The planned sample size of the 142 patients in the two groups will enable us to detect a difference with a power of 80% by using the Wilcoxon rank sum test, assuming an effect size of 0.54, asymptotic relative efficiency of 0.864 and a two-sided type 1 error rate of 5%. ETHICS AND DISSEMINATION: This trial was approved by the certified review board of Kobe University (22 December 2022). The results from this trial will be disseminated through peer-review journals, presentations at national and international conferences, and data sharing with other researchers. TRIAL REGISTRATION NUMBER: jRCT1052220166.

A 53-year-old Japanese man presented to the emergency department with epigastric pain and bloating. Computed tomography revealed a thickening of the jejunal wall and proximal dilation. Double-balloon enteroscopy was performed to investigate the jejunal thickening, which revealed an anisakis larva in the jejunum with an associated ulcer. The larva was removed using endoscopic forceps, after which there was immediate improvement of symptoms. Further patient interview determined that he had consumed marinated mackerel the day before the onset of symptoms. After diagnosis of small intestinal anisakiasis, he was successfully treated using double-balloon enteroscopy. Its use for small intestinal anisakiasis is rare, and this case may be the first instance in the jejunum. Removal of the anisakis larva led to a clear diagnosis and a quick resolution of symptoms. A history of raw fish consumption a few days before the onset of abdominal symptoms and abnormal findings on computed tomography scans are key to the diagnosis of small intestinal anisakiasis. Double-balloon enteroscopy was thought to be a safe means of making accurate diagnoses and appropriate treatment of our patients.
RESUMO
BACKGROUND AND AIMS: Perforation during esophageal endoscopic submucosal dissection (ESD) typically results from electrical damage. However, there are cases in which perforation occurs because of segmental absence of intestinal musculature (SAIM) without iatrogenic muscular injury. We investigated the occurrence rate and clinical course of SAIM during esophageal ESD. METHODS: We conducted a retrospective review of esophageal ESDs performed between 2013 and 2019 at 10 centers in Japan. RESULTS: Five of 1708 (0.29%) patients received ESD for esophageal cancer and had SAIM. The median muscular defect size was 20 mm. All lesions were resected without discontinuation. After resection, 3 patients were closed with Endoloop. Four patients had mediastinal emphysema. All patients were managed conservatively. CONCLUSIONS: SAIM is a very rare condition that is usually only diagnosed during ESD. Physicians performing esophageal ESD should be aware of SAIM. When SAIM is detected, the ESD technique should be modified to prevent full-thickness perforation.

OBJECTIVES: Early gastric cancer endoscopic resection (ER) is prominent in Japan. However, evidence regarding ER of gastric submucosal tumors (SMT) is limited. This prospective multicenter phase II study investigated the efficacy and safety of endoscopic full-thickness resection (EFTR) for gastric SMT. METHODS: Endoscopic full-thickness resection indication for gastric SMT was 11-30 mm, histologically proven or clinically suspicious (irregular margin, increasing size, or internal heterogeneity) gastrointestinal stromal tumors (GIST), with no ulceration and intraluminal growth type. The primary end-point was the complete ER (ER0) rate, with a sample size of 42. RESULTS: We enrolled 46 patients with 46 lesions between September 2020 and May 2023 at seven Japanese institutions. The mean ± SD (range) endoscopic tumor size was 18.8 ± 4.5 (11-28) mm. The tumor resection and defect closure times were 54 ± 26 (22-125) min and 33 ± 28 (12-186) min, respectively. A 100% ER0 was achieved in all 46 patients. The EFTR procedure was accomplished in all patients without surgical intervention. One patient had delayed perforation and was managed endoscopically. GIST accounted for 76% (n = 35) of the cases. R0, R1, and RX rates were 33 (77%), 3 (6.5%), and 7 (15%), respectively. CONCLUSION: Endoscopic full-thickness resection for gastric SMT of 11-30 mm is efficacious. It warrants further validation in a large-scale cohort study to determine the long-term outcome of this treatment for patients with gastric GIST.
RESUMO
Not all patients with ulcerative colitis (UC) respond initially to treatment with biologic agents, and predicting their efficacy prior to treatment is difficult. Vedolizumab, a humanized monoclonal antibody against alpha 4 beta 7 (α4ß7) integrin, suppresses immune cell migration by blocking the interaction between α4ß7 integrin and mucosal addressin cell adhesion molecule 1. Reports about histological features that predict vedolizumab efficacy are scarce. So, we examined the association between histological features and vedolizumab efficacy. This was a multicenter, retrospective study of patients with UC treated with vedolizumab. Biopsy specimens taken from the colonic mucosa prior to vedolizumab induction were used, and the areas positively stained for CD4, CD68, and CD45 were calculated. Clinical and histological features were compared between those with and without remission at week 22, and the factors associated with clinical outcomes were identified. We enrolled 42 patients. Patients with a high CD4+ infiltration showed a better response to vedolizumab [odds ratio (OR) = 1.44, P = 0.014]. The concomitant use of corticosteroids and high Mayo scores had a negative association with the vedolizumab response (OR = 0.11, P = 0.008 and OR = 0.50, P = 0.009, respectively). Histological evaluation for CD4+ cell infiltration may be helpful in selecting patients who can benefit from vedolizumab.

OBJECTIVES: Endoscopic submucosal dissection (ESD) for superficial esophageal squamous cell carcinoma (ESCC) is performed for the treatment of lesions with varied backgrounds and factors. However, the predictive factors associated with the technical difficulty of ESD remain unknown in patients with varied lesions. Therefore, this study aimed to identify the predictive factors associated with the technical difficulty of ESD for ESCC using a retrospective cohort. METHODS: This multicenter, retrospective study was conducted in 10 hospitals in Japan. Consecutive patients who underwent esophageal ESD between January 2013 and December 2019 were enrolled. Lesions of subepithelial tumors, adenocarcinoma, and adenoma were excluded. Difficult lesions were defined as ESD requiring a long procedure time (≥120 min), perforation development, piecemeal resection, or discontinued ESD. In the present study, the clinical factors were assessed to identify the technical difficulty of ESD using univariate and multivariate analyses. RESULTS: Among 1708 lesions treated with esophageal ESD, eight subepithelial tumors, 44 adenocarcinomas, and two adenomas were excluded. Finally, 1505 patients with 1654 lesions were analyzed, and 217 patients with 217 lesions (13.1%) were classified as patients with difficult lesions. In multivariate analysis, the predictive factors associated with the technical difficulty of ESD were as follows: tumors with varices, tumors with diverticulum, antiplatelet use (discontinued), circumference of tumor (≥1/2), preoperative tumor size ≥30 mm, trainee, and nonhigh-volume center. CONCLUSION: This multicenter retrospective study identified the predictive factors associated with the technical difficulty of ESD for ESCC with varied backgrounds and factors.
RESUMO
INTRODUCTION: Favorable long-term outcomes of endoscopic submucosal dissection (ESD) for early remnant gastric cancer (ERGC) have been reported in single-center studies from advanced institutions. However, no studies have examined the long-term outcomes using a multicenter database. This study aimed to investigate the long-term outcomes of the aforementioned approach using a large multicenter database. METHODS: This retrospective multicenter cohort study included 242 cases with 256 lesions that underwent ESD for ERGC between April 2009 and March 2019 across 12 centers. We investigated the long-term outcomes of these patients with the Kaplan-Meier method, and the relationship between curability, additional treatment, or hospital category, and the survival time was evaluated using the log-rank test. RESULTS: During the median follow-up period of 48.4 months, the 5-year overall survival rate was 81.3%, and the 5-year gastric cancer-specific survival rate was 98.1%. The survival time of patients of endoscopic curability (eCura) C-2 without additional surgery was significantly shorter than the corresponding of patients of eCura A/B/C-1 and eCura C-2 with additional surgery. There was no significant difference in either overall survival or gastric cancer-specific survival rate between the high-volume and non-high-volume hospitals. CONCLUSION: The gastric cancer-specific survival of ESD for ERGC using a multicenter database was favorable. ESD for ERGC is widely applicable regardless of the hospital case volume. Management in accordance with the latest guidelines will lead to long-term survival.

BACKGROUND: Heavy drinking is associated with esophageal cancer and esophageal varices. However, there are limited reports of endoscopic resection for esophageal cancer with esophageal varices. In this multicenter study, we clarified the safety and efficacy of endoscopic submucosal dissection for superficial esophageal cancer with esophageal varices. METHODS: In this multicenter, retrospective, observational study, patients underwent esophageal endoscopic submucosal dissection at 10 referral centers in Japan from January 2013 to December 2019. We analyzed characteristics including backgrounds and varices, treatment outcomes, and adverse events in cases with esophageal varices. RESULTS: A total of 1708 patients were evaluated, 27 (1.6%) of whom had esophageal varices. In patients with esophageal varices, the en bloc resection rate and R0 resection rate were 100% and 77.8%, respectively. Patients with esophageal varices had longer procedure times than patients without esophageal varices (p = 0.015). There was no significant difference in adverse events. There was no significant difference in procedure time and number of adverse events between patients who underwent pretreatment and those who did not. There was no significant difference in these outcomes for patients with lesions on varices compared to those without. Child-Pugh classification and location of the lesions also did not affect these outcomes. CONCLUSIONS: Esophageal cancer with esophageal varices could be treated endoscopically safely and effectively.

BACKGROUND: Adenocarcinoma is preceded by chronic atrophic gastritis, gastric intestinal metaplasia and dysplasia. Trefoil factor 3 (TFF3) is a peptide secreted by goblet cells, which is abundantly present in intestinal metaplasia. AIM: To evaluate the utility of serum TFF3 as a non-invasive biomarker for the diagnosis of intestinal metaplasia and gastric cancer. METHODS: Single-center, cross-sectional study of 274 patients who consecutively underwent upper gastrointestinal endoscopy with gastric biopsies (updated Sydney system). TFF3 levels were measured in serum by a commercial ELISA kit. Patients with normal histology or chronic atrophic gastritis without intestinal metaplasia comprised the control group. In addition, 14 patients with invasive gastric cancer were included as a reference group. The association between TFF3 levels and intestinal metaplasia was assessed by logistic regression. RESULTS: Patients with intestinal metaplasia (n=110) had a higher median TFF3 level as compared to controls (n=164), 13.1 vs. 11.9ng/mL, respectively (p=0.024). Multivariable logistic regression showed a no significant association between TFF3 levels and intestinal metaplasia (OR=1.20; 95%CI: 0.87-1.65; p-trend=0.273). The gastric cancer group had a median TFF3 level of 20.5ng/mL, and a significant association was found (OR=3.26; 95%CI: 1.29-8.27; p-trend=0.013). CONCLUSION: Serum levels of TFF3 do not discriminate intestinal metaplasia in this high-risk Latin American population. Nevertheless, we confirmed an association between TFF3 levels and invasive gastric cancer.

OBJECTIVES: Limited information is available on the efficacy and safety of endoscopic resection (ER) of gastric submucosal tumors (SMTs) in Japanese endoscopic practice where ER for gastric tumors is extremely popular. METHODS: We conducted this study to elucidate the current scenario of ER for gastric SMTs in Japanese endoscopic practice. Patients (from 12 institutions) with gastric SMTs who underwent ER were enrolled from the first case until August 2020. RESULTS: We enrolled 117 patients with 118 lesions. The number of patients who underwent ER increased over the years. The mean endoscopic tumor size was 20 ± 7.2 (8-40) mm. The growth type was primarily intraluminal (90%). The mean resection and wound closure times were 58 ± 38 (range, 12-254) min and 31 ± 41 (range, 3-330) min, respectively. Complete ER was achieved for 117 (99%) lesions. Full-thickness resection rate was 44%; however, only 12 (10%) patients required abdominal paracentesis for decompression. Endoscopic treatments were completed in 115 (97%) lesions, while three lesions required conversions to laparoscopic surgery due to luminal collapse, uncontrolled bleeding, and difficulty in defect closure. Gastrointestinal stromal tumors were the most common pathology (74%). No recurrence was observed during the mean follow-up period of 4.3 ± 2.9 years. The 5-year overall survival rate was 98.9% (95% confidence interval 97.8-100%). CONCLUSION: Performance of ER for gastric SMTs is increasing in Japan. The technique seems feasible in Japanese endoscopic practice, warranting further validation in a prospective study.

BACKGROUND: Endoscopic submucosal dissection (ESD) for remnant gastric cancer (RGC) after distal gastrectomy (DG) is considered technically challenging due to the narrow working space, and severe fibrosis and staples from the previous surgery. Technical difficulties of ESD for RGC after DG have not been thoroughly investigated. This study aimed to develop and validate a risk-scoring system for assessing the technical difficulty of ESD for RGC after DG in a large multicenter cohort. METHODS: We investigated patients who underwent ESD for RGC after DG in 10 institutions between April 2008 and March 2018. A difficult case was defined as ESD lasting ≥ 120 min, involving piecemeal resection, or the occurrence of perforation during the procedure. A risk-scoring system for the technical difficulty of the procedure was developed based on multiple logistic regression analyses, and its performance was internally validated using bootstrapping. RESULTS: A total of 197 consecutive patients with 201 lesions were analyzed. There were 90 and 111 difficult and non-difficult cases, respectively. The scoring model consisted of four independent risk factors and points of risk scores were assigned for each as follows: tumor size > 20 mm: 2 points; anastomosis site: 2 points; suture line: 1 point; and non-expert endoscopist: 2 points. The C-statistics of the scoring system for technical difficulty was 0.72. CONCLUSIONS: We developed a validated risk-scoring model for predicting the technical difficulty of ESD for RGC after DG that can contribute to its safer and more reliable performance.

OBJECTIVES: Recently, several studies have demonstrated the usefulness of endoscopic submucosal dissection (ESD) for residual or locally recurrent colorectal lesions after endoscopic treatment. However, the feasibility of ESD for recurrent rectal lesions after transanal endoscopic microsurgery (TEM) has not been fully investigated. In this study, we evaluated the feasibility and safety of ESD for recurrent rectal lesions after TEM. METHODS: The treatment outcomes of 10 lesions in 9 patients, who underwent ESD between January 2006 and March 2018 for recurrent rectal lesions after transanal endoscopic microsurgery, were evaluated. RESULTS: All lesions were successfully resected en bloc, and the R0 resection rate was 90%. The median size of the resected specimens and lesions (range) was 44 mm (21-70) and 27.5 mm (5-60), respectively. The pathological diagnoses included 4 adenomas and 6 cancerous lesions. The cancerous lesions included 5 cases of mucosal cancer and 1 case of superficial submucosal invasive cancer (depth of submucosal invasion <1,000 µm from the muscularis mucosae). No adverse events occurred. There was no recurrence during the follow-up period. CONCLUSIONS: ESD for recurrent rectal lesions after TEM by expert's hands appears to be safe and feasible.

BACKGROUND: Despite a need for assessment of endoscopic submucosal dissection (ESD) skills in order to track progress and determine competence, there is no structured measure of assessing competency in ESD performance. The present study aims to develop and examine validity evidence for an assessment tool to evaluate the recorded performance of ESD for gastric neoplasms. METHODS: The ESD video assessment tool (EVAT) was systematically developed by ESD experienced endoscopists. The EVAT consists of a 25-item global rating scale and 3-item checklist to assess competencies required to perform ESD. Five unedited videos were each evaluated by 2-blinded experienced ESD endoscopists to assess inter-rater reliability using intraclass correlation coefficients (ICC). Seventeen unedited videos in total were rated by 3 blinded experienced ESD endoscopists. Validity evidence for relationship to other variables was examined by comparing scores of inexperienced (fellows) and experienced endoscopists (attending staff), and by evaluating the relationship between the EVAT scores and ESD case experience. Internal consistency was evaluated using Cronbach's alpha. RESULTS: The inter-rater reliability for the total score was high at 0.87 (95% confidence interval 0.11 to 0.99). The total score [median, interquartile range (IQR)] was significantly different between the inexperienced (71, 63-77) and experienced group (95, 91-97) (P = 0.005). The total scores demonstrated high correlation with the number of ESD cases (Spearman's ρ = 0.79, P < 0.01). The internal consistency was 0.97. CONCLUSIONS: This study provides preliminary validity evidence for the assessment of video-recorded ESD performances for gastric neoplasms using EVAT.

Background and study aims Patients who have undergone colorectal surgery for resection of cancer and benign lesions are at risk for recurrent, residual, or metachronous lesions at the anastomosis site. Surgical resection of such lesions is difficult because of adhesions, and a stoma may be required as there are risks for leakage after resection. The feasibility and safety of endoscopic submucosal dissection (ESD) for these lesions remain unknown. Therefore, this case series aimed to examine the feasibility and safety of ESD by evaluating the clinical outcomes. Patients and methods We retrospectively investigated five patients who underwent ESD by a single expert for superficial neoplastic lesions at the anastomosis site after previous colorectal surgery. Results R0 resections were achieved for all lesions. Mean procedure time was 160.6 minutes. Mean dimensions of the resected specimen and tumor were 52.4âmm and 31.8mm, respectively. None of the patients had complications or recurrence after surveillance colonoscopy 1-year post-resection. Conclusions In an expert's hands, ESD at the anastomosis site might be feasible minimally invasive treatment for superficial neoplastic lesions.
RESUMO
BACKGROUND AND STUDY AIMS: Gastrointestinal (GI) fistulas arise as adverse events of GI surgery and endoscopic treatment as well as secondary to underlying diseases, such as ulceration and pancreatitis. Until a decade ago, they were mainly treated surgically or conservatively. Bioabsorbable polyglycolic acid (PGA) sheets and fibrin glue, which are commonly used in surgical procedures, have also recently been used in endoscopic procedures for the closure of GI defects. However, there have only been few case reports about successful experiences with this approach. There have not been any case-series studies investigating the strengths and weaknesses of such PGA sheet-based treatment. In this study, we evaluated the clinical effectiveness of using PGA sheets to close GI fistulas. PATIENTS AND METHODS: Cases in which patients underwent endoscopic filling with PGA sheets and fibrin glue for GI fistulas at Kobe University Hospital between January 2013 and April 2018 were retrospectively reviewed. RESULTS: A total of 10 cases were enrolled. They included fistulas due to leakage after GI surgery, aortoesophageal/bronchoesophageal fistulas caused by chemoradiotherapy, or severe acute pancreatitis. The fistulas were successfully closed in 7 cases (70%). The unsuccessful cases involved a fistula due to leakage after surgical esophagectomy and bronchoesophageal fistulas due to chemoradiotherapy or severe acute pancreatitis. Unsuccessful treatment was related to fistula epithelization. CONCLUSION: Endoscopic plombage with PGA sheets and fibrin glue could be a promising therapeutic option for GI fistulas.

A 73-year-old female with a 6-month history of progressive dysphagia and chest pain was referred to our hospital. She underwent esophagogastroduodenoscopy, which revealed abnormally strong contractions in the distal esophagus. Esophageal biopsy specimens showed massive eosinophil infiltration into the epithelium, and high-resolution manometry (HRM) also demonstrated abnormally strong contractions in the distal esophagus. Based on these results, she was diagnosed with Jackhammer esophagus (JHE) due to eosinophilic esophagitis (EoE). Treatment was started with 5 mg/day of prednisolone (PSL), and the number of peripheral blood eosinophils quickly decreased without any improvement in the patient's dysphagia. Esophageal biopsy specimens obtained after the PSL treatment showed the disappearance of eosinophils from the epithelium. However, abnormally strong contractions were still detected on HRM. Per-oral endoscopic myotomy (POEM) was performed to treat the JHE. Interestingly, the intraoperative esophageal muscle biopsy sample demonstrated massive eosinophil infiltration into the muscle layer. After the POEM, the patient's symptoms improved, and abnormal contractions were no longer detected on HRM. The current case suggests that when EoE combined with an esophageal motility disorder are refractory to steroid therapy, clinicians should be aware that motility disorders can develop due to eosinophil infiltration deep into the esophageal muscularis propria.
