RESUMO
Background and aim: Ulcerative colitis (UC) is characterized by repeated relapse and remission. Because no fundamental therapeutic strategy has been established, the treatment goal is generally to maintain the remission phase for a long period after rapid remission induction. Granulocyte and monocyte adsorption (GMA) for UC is reportedly quite safe because it does not affect immunosuppression. Moreover, it is useful in combination with other remission induction therapy. The aim of this study was to evaluate the difference in efficacy by the timing of the addition of GMA with corticosteroids, calcineurin inhibitors, and anti-cytokine therapy for active UC. Methods: The study included 59 patients. Patients who started GMA of 5-11 days were in the early GMA combination group. Patients who started GMA 12 days or more were in the late GMA combination group. The primary endpoint was difference in the effect of additional GMA according to the timing of the intervention. The secondary endpoint was difference in the time to remission induction between the two groups. Results: Of the 32 early GMA group patients, 24 achieved remission induction. Of the 27 late group patients, 18 achieved remission induction. No significant difference in induction rates was found (P = 0.481). The early group had shorter mean time to remission induction (P < 0.001). Conclusions: In conclusion, results suggest that early addition of GMA might lead to earlier remission in patients who have had an inadequate response to remission induction therapy with corticosteroids, calcineurin inhibitors, and anti-cytokine therapy.
RESUMO
Symptoms of traumatic duodenal intramural hematoma, a rare disease caused by trauma, blood disease, or antithrombotic therapy, can include abdominal pain. Case 1 is that of a 35-year-old man at a gym who dropped a 100 kg barbell on his abdomen. It was diagnosed as a duodenal obstruction caused by a traumatic intestinal wall hematoma. In Case 2, a 16-year-old male adolescent performing deadlift training at a gym had subsequent abdominal pain. It was diagnosed as intestinal wall hematoma. Both patients improved with conservative treatment. Malignancy is sometimes suspected from imaging findings. Detailed patient history and imaging studies can avoid unnecessary surgery.

INTRODUCTION: Since patients with pharyngeal squamous cell carcinoma (SCC) often have multiple pharyngeal lesions, evaluation of pharyngeal lesions before endoscopic resection (ER) is important. However, detailed endoscopic observation of the entire pharyngeal mucosa under conscious sedation is difficult. We examined the usefulness of endoscopic surveillance with narrow band imaging (NBI) and lugol staining for detection of pharyngeal sublesions during ER for pharyngeal SCC under general anesthesia (endoscopic surveillance during treatment; ESDT). METHODS: From January 2021 through June 2022, we examined 78 patients who were diagnosed with superficial pharyngeal SCC and underwent ER. They underwent the ESDT and for patients who were diagnosed with new lesions of pharyngeal SCC or high-grade dysplasia (HGD) that were not detected in the endoscopic examination before treatment, ER were performed simultaneously for new lesions and the main lesions. The primary endpoint of this study was the detection rate of new lesions of pharyngeal SCC or HGD in the ESDT. RESULTS: Fifteen of the 78 patients were diagnosed as having undetected new pharyngeal lesions in the ESDT and 10 (12.8%) (95% CI 6.9-22.2%) were histopathologically confirmed to have new lesions of pharyngeal SCC or HGD. Among the 13 lesions of SCC or HGD, 8 were found by NBI observation; however, 5 were undetectable using NBI but detectable by lugol staining. All of the 13 lesions had endoscopic findings of pink color sign on lugol staining. CONCLUSIONS: Endoscopic surveillance for pharyngeal sublesions during ER for pharyngeal SCC is feasible and useful.

Background: Although endoscopic submucosal dissection (ESD) provides a high rate of curative resection, the remaining gastric mucosa after ESD is at risk for metachronous superficial gastric epithelial neoplasms (MSGENs). It leaves room for risk factors for developing MSGENs after ESD. This study aimed to identify clinicopathological risk factors for the occurrence of MSGENs, and to evaluate the association of Helicobacter pylori (H. pylori) with the MSGENs. Methods: We conducted a retrospective cohort study including 369 patients with 382 lesions that underwent ESD for adenoma/early gastric cancer. Results: Twenty-seven MSGENs occurred. The subjects were divided into MSGEN and not-MSGEN groups. There was a significantly higher frequency of histological intestinal metaplasia (HIM) and initial neoplasm location in the upper or middle parts (INUM) in the MSGEN group. The HIM and INUM groups had a significantly higher cumulative incidence of MSGENs. We compared 27 patients from the MSGEN group and 27 patients from the not-MSGEN group that were matched to the MSGEN group for variables including HIM and INUM. There was a significantly higher frequency of the spontaneous disappearance of H. pylori in the MSGEN group. Conclusions: HIM, INUM, and the spontaneous disappearance of H. pylori may be clinicopathological risk factors for developing MSGENs after ESD.
RESUMO
Esophageal squamous cell carcinoma (SCC) with dark spots caused by melanocytosis is very rare. A reddish and flat lesion, 4 cm in length and covering over two-thirds of the circumference, was found in the midthoracic esophagus of a 66-year-old male. Multiple brown and black spots are observed in the lesion. Superficial SCC with melanocytosis or malignant melanoma was also suspected. Endoscopic submucosal dissection was performed without biopsies of the spots. Histologically, a few melanocytes were observed in the black spots, and the lesion was diagnosed as SCC (T1a-lamina propria mucosae) with melanocytosis. We report a case of esophageal SCC with dark black spots that were difficult to differentiate endoscopically from malignant melanoma.
RESUMO
BACKGROUND: We previously developed a Japan Esophageal Society Barrett's Esophagus (JES-BE) magnifying endoscopic classification for superficial BE-related neoplasms (BERN) and validated it in a nationwide multicenter study that followed a diagnostic flow chart based on mucosal and vascular patterns (MP, VP) with nine diagnostic criteria. Our present post hoc analysis aims to further simplify the diagnostic criteria for superficial BERN. METHODS: We used data from our previous study, including 10 reviewers' assessments for 156 images of high-magnifying narrow-band imaging (HM-NBI) (67 dysplastic and 89 non-dysplastic histology). We statistically analyzed the diagnostic performance of each diagnostic criterion of MP (form, size, arrangement, density, and white zone), VP (form, caliber change, location, and greenish thick vessels [GTV]), and all their combinations to achieve a simpler diagnostic algorithm to detect superficial BERN. RESULTS: Diagnostic accuracy values based on the MP of each single criterion or combined criteria showed a marked trend of being higher than those based on VP. In reviewers' assessments of visible MPs, the combination of irregularity for form, size, or white zone had the highest diagnostic performance, with a sensitivity of 87% and a specificity of 91% for dysplastic histology; in the assessments of invisible MPs, GTV had the highest diagnostic performance among the VP of each single criterion and all combinations of two or more criteria (sensitivity, 93%; specificity, 92%). CONCLUSION: The present post hoc analysis suggests the feasibility of further simplifying the diagnostic algorithm of the JES-BE classification. Further studies in a practical setting are required to validate these results.

We herein report a rare case of hereditary diffuse gastric cancer in a Japanese man. A 41-year-old man underwent esophagogastroduodenoscopy which revealed a small gastric erosion. Biopsy specimens showed signet ring cell carcinoma, and endoscopic submucosal dissection was performed. The patient's elder sister had died of gastric cancer at 38 years old. Considering the family history, a genetic test was conducted and revealed a CDH1 germline mutation. Although no carcinomatous lesion was detected endoscopically, prophylactic total gastrectomy was performed. The resection specimen showed seven microlesions of signet ring cell carcinoma confined to the lamina propria mucosae.

BACKGROUND: Although bile reflux plays an important role in the development of Barrett's esophagus, the relationship between endoscopic findings of bile reflux and Barrett's esophagus remains unclear. OBJECTIVE: This study evaluated whether endoscopic evidence of bile reflux was associated with the presence of Barrett's esophagus. METHODS: A retrospective analysis of a prospectively maintained database comprising consecutive patients who underwent screening esophagogastroduodenoscopy was conducted. Endoscopic evidence of bile reflux was defined as the presence of bile-stained fluid in the gastric fundus. We performed multivariate analysis to identify predictive factors that differed significantly between patients with and without Barrett's esophagus. RESULTS: Of 4021 patients, 922 (23%) had Barrett's esophagus, and 1000 (25%) showed endoscopic findings of bile reflux. Multivariate analysis revealed endoscopic evidence of bile reflux as the strongest independent factor associated with the presence of Barrett's esophagus (odds ratio [OR] 5.65, 95% confidence interval [CI] 4.71-6.76) in relation to the presence of hiatal hernia (OR 3.30, 95% CI 2.70-4.04) and male gender (OR 1.54, 95% CI 1.24-1.91). CONCLUSIONS: Endoscopic evidence of bile reflux was independently associated with the presence of Barrett's esophagus. This finding might help identify patients at future risk of Barrett's esophagus who could benefit from increased endoscopy surveillance.

[Aim and Background] People's lifestyles changed considerably due to the coronavirus disease 2019 (COVID-19) pandemic. The number of patients with acute pancreatitis (AP) can be expected to decrease as alcohol consumption decreases. This study was conducted to assess COVID-19 pandemic effects on AP patients in a Japanese regional hospital. [Methods] Based on the first and second states of emergency declarations in Tochigi Prefecture, the survey periods were set as follows: period A, 16 April-14 May; period B, 15 May-13 January; period C, 14 January-7 February; and period D, 8 February-15 April. Using data acquired in 2017, 2018, 2019, and 2020, we retrospectively reviewed the number of patients admitted to our hospital with a diagnosis of AP, and their clinical characteristics. [Results] According to a National Tax Agency survey, the average alcohol sales per adult in Tochigi Prefecture were 71.3 L in 2017 before the pandemic, and 64.0 L in 2021 under the pandemic. The number of AP patients in 2020 was 38% lower than in 2017. Comparing 2017 with 2020, the number of alcoholic AP patients was lower in 2020 (p = 0.007). [Conclusions] The findings suggest that COVID-19-pandemic-related lifestyle changes contributed to the decrease in AP patients.
RESUMO
[Background and study aim] A commonly applied method for diagnosing chronic pancreatitis (CP) uses endoscopic ultrasonography (EUS), assigning weights to each EUS diagnostic finding. It is the Rosemont classification (RC). In 2019, to improve EUS diagnostic specificity, Japanese diagnostic criteria for early chronic pancreatitis (ECP) were revised. Nevertheless, the criteria use no weighting of EUS diagnostic findings, as the RC does. This study was undertaken to propose diagnostic criteria that would weight each EUS finding of ECP and that would be more specific than the RC. [Methods] By EUS of the pancreas, 773 patients underwent detailed observation from January 2018 to March 2019 at our institution. An expert finalized all cases when patients were diagnosed. Using data from the medical records, 97 consecutive patients with EUS diagnostic findings of ECP based on the Japanese diagnostic criteria of ECP2009 (JDCECP2009) were selected. The definition under the RC of "Indeterminate for CP" was equivalent to ECP. Each case was diagnosed using (1) JDCECP2009 and (2) the Japanese diagnostic criteria of ECP2019 (JDCECP2019). Moreover, the four diagnostic EUS findings in JDCECP2019 were applied to the RC, weighted (modified-JDCECP2019), and subsequently compared with the earlier diagnostic criteria. As Modified-JDCECP2019, we suggested (3) RC-A-the current four items scored related to the RC, and (4) RC-B-the five items scored by dividing lobularity with and without honeycombing. [Results] Diagnoses produced based on each criterion were normal: ECP = (1) 20:77, (2) 46:51, (3) 52:42, and (4) 60:35. [Conclusions] Modified-JDCECP2019 may provide EUS diagnoses for ECP with higher specificity.
RESUMO
A woman in her 60s underwent endoscopic sphincterotomy for choledocholithiasis. Unfortunately, post-endoscopic retrograde cholangiopancreatography pancreatitis occurred. In addition, huge walled-off necrosis (WON) appeared as a late complication. For the infected WON, endoscopic ultrasound-guided fistuloplasty and endoscopic necrosectomy were performed, and a double pigtail plastic stent (PS) (7Fr, 7 cm) was placed to prevent a recurrence. Plain computed tomography conducted two years later showed that the stent implanted for WON had deviated. The distal end of the stent was found to have migrated into the bile duct. In addition, common bile duct stones with stents as nuclei were observed. Upon performing endoscopic retrograde cholangiography, it was revealed that the stent tip perforated the distal bile duct just above the papilla. After removal of the stent using grasping forceps, we made an incision between the duodenal - bile duct fistula and bile duct orifice using a sphincterotome. Then, the stone was removed by a balloon catheter. Although such late adverse events are rare occurrences, placement of long-term PS after treatment of WON should be followed up regularly with imaging examination, and if there is no recurrence for several months, removal of the PS at that point may be considered.
RESUMO
BACKGROUND AND AIM: Small gastric subepithelial lesions (SELs) are sometimes encountered in daily esophagogastroduodenoscopy (EGD) practice, but whether once-annual or twice-annual endoscopy can provide sufficient follow-up remains unclear. Because follow-up based on small-SEL characteristics is important, this study clarified the natural history of gastric SELs less than 20 mm. METHODS: This retrospective multicenter observation study conducted at 24 Japanese hospitals during April 2000 to March 2020 examined small gastric SELs of ≤20 mm diameter. The primary outcome was the rate of size increase of those SELs detected using EGD, with growth times assessed irrespective of SEL pathological diagnoses. RESULTS: We examined 824 cases with tumors of 1-5 mm diameter in 298 (36.2%) cases, 6-10 mm in 344 (41.7%) cases, 11-15 mm in 112 (13.6%) cases, and 16-20 mm in 70 (8.50%) cases. An increase of small gastric SELs was observed in 70/824 patients (8.5%). The SELs larger than 6 mm increased, even after 10 years. No-change and increasing groups had no significantly different malignant findings at diagnosis. In cases of gastrointestinal stromal tumors (GISTs), internal cystic change in endoscopic ultrasound (EUS) is a risk factor for an increased tumor size. The predictive tumor growth cutoff size at initial diagnosis was 13.5 mm. CONCLUSIONS: Small gastric SELs less than 20 mm have an approximately 8.5% chance of increase. Predictive markers for GIST growth are tumor size ≥13.5 mm and internal cystic change in EUS.

The patient, a 73-year-old woman, had been taking acid-suppressive therapy for refractory reflux esophagitis for 10 years. A potassium-competitive acid blocker was administered to strengthen acid-suppressive therapy for worsening symptoms of gastroesophageal reflux disease. Esophagogastroduodenoscopy showed an increase in the number and size of fundic gland polyposis (FGPs). When acid-suppressive therapy was changed from potassium-competitive acid blocker to proton pump inhibitor, the FGPs showed reduced size 1 year later. Furthermore, when acid-suppressive therapy was changed from proton pump inhibitor to histamine-2 receptor antagonist, FGPs were even smaller after 1 and 2 years. The patient, who had no flare-up of gastroesophageal reflux disease symptoms, continues to be treated medically with histamine-2 receptor antagonist. This case report describes changes in endoscopic findings of a patient with FGPs caused by acid-suppressive therapy for refractory gastroesophageal reflux disease.
RESUMO
A 38-year-old woman was admitted to our hospital for a detailed examination of jaundice. Three years before, she had undergone a right total mastectomy and axillary lymph node dissection of her right breast because of cancer. Histopathological evaluation revealed invasive ductal carcinoma. Postoperatively, because multiple bone metastases were found, she underwent chemoradiotherapy. Endoscopic retrograde cholangiopancreatography was performed, which revealed widespread multiple stenoses with a smooth surface from the intrahepatic to the extrahepatic bile duct. A transpapillary biliary biopsy was performed. Histopathological examination revealed adenocarcinoma extending into the subepithelium of the bile duct. The obtained cancer cells were similar to those of the earlier invasive breast cancer. This rare case demonstrates bile duct metastasis of breast cancer with specific endoscopic retrograde cholangiopancreatography findings.
RESUMO
Endoscopic ultrasound (EUS) is widely recognized for its non-invasiveness and for its usefulness in chronic pancreatitis (CP) diagnosis, including early CP. Although it is desirable to obtain a definitive diagnosis of CP by tissue sampling with EUS-guided fine needle aspiration, histopathological changes in CP are heterogeneous in terms of the extent and the distribution of lesions. Therefore, histopathological diagnosis of appropriate tissue sampling by EUS-fine needle aspiration is expected to be difficult. Furthermore, it is virtually impossible to match EUS images with pathological sections, making direct contrast between EUS findings and pathology difficult. This narrative review presents a discussion of the diagnosis of CP/early CP by EUS, particularly assessing the association between ultrasound and pathological findings. Recently, the histological corroboration and correlation of EUS findings related to CP have been clarified by surgical specimens, including those obtained from animal studies. Furthermore, remarkable advances have occurred in the objective and quantitative diagnosis of pancreatic fibrosis by EUS-elastography. Future technological advances in EUS are expected to improve the accuracy of diagnosis of pancreatic fibrosis at earlier stages.
RESUMO
Advanced endoscopy (AVE) techniques include image-enhanced endoscopy methods, such as narrow-band imaging (NBI), and types of microscopic endoscopy, such as endocytoscopy. In the esophagus, AVE first showed diagnostic utility in the diagnosis of superficial esophageal cancer and was then applied to inflammatory disease. This review focuses on non-erosive reflux disease (NERD) and eosinophilic esophagitis (EoE), which sometimes show no abnormal findings on standard white light endoscopy alone. Studies have demonstrated that advanced endoscopy, including NBI magnification endoscopy and endocytoscopy, improved the diagnostic performance of white-light endoscopy alone for NERD and EoE. In this review, we explain why advanced endoscopy is needed for the diagnosis of these esophageal inflammatory diseases, summarize the study results, and discuss future perspectives.
RESUMO
Red color sign-positive (RC-positive) esophageal varices present a high bleeding risk, necessitating prophylactic treatment. Among RC-positive esophageal varices, those classified morphologically as small straight varices (Form level 1: F1) are difficult to treat. Moreover, the appropriate time for therapeutic intervention remains undefined. This study assessed the bleeding risk in RC-positive F1 esophageal varices. After extracting 541 cases of F1 esophageal varices diagnosed during 1 January 2012−29 February 2020, 76 cases of RC-positive F1 esophageal varices were divided into two groups in terms of treatment intervention at diagnosis: 49 cases with (treatment group) and 27 cases without (follow-up group). We assessed the bleeding rates, bleeding-associated factors, and early-bleeding-associated factors. The treatment group's bleeding rate was 10% (5/49). The follow-up group's bleeding rate was 78% (21/24). The subsequent bleeding rate was low in the treatment group (p < 0.001). The median period of sustained absence of bleeding was longer in the treatment group than in the follow-up group (1156 [274−1582] days vs. 105 [1−336] days; p < 0.001). In the follow-up group, a significant number of bleedings had varices that included a hematocystic spot (HCS) as RC or combined with RC (p = 0.017). Early bleeding occurred often in varices that included HCS or combined with RC (p = 0.024). Red wale marking (RWM) only was not a factor of early bleeding (p = 0.012). In conclusion, RC-positive varices should be treated even as F1 varices. Patients with RWM only show the possibility of not accepting early treatment intervention. A fast response is crucially important in HCS cases because of its associated bleeding and early bleeding.
RESUMO
INTRODUCTION: Hematochezia is observed frequently in daily practice. However, natural hemostasis often prevents identification of the bleeding source during observations. This study was conducted to clarify risk factors related to rebleeding in hematochezia patients without an identified cause of bleeding. METHODS: We analyzed patients who were admitted to Dokkyo Medical University Hospital during April 1, 2009, through March 31, 2015, with the chief complaint of hematochezia. Main outcome measures included the rebleeding rate and the period until rebleeding in hematochezia patients without an identified bleeding source. RESULTS: We selected 159 patients for analyses. Rebleeding was observed in 46 (28.9%) of 159 patients. The median period until first rebleeding was 166 days (2-3,046 days). Univariate analysis indicated that risk factors for rebleeding were male gender (p = 0.029), higher age (p = 0.023), antithrombotic medicines (p = 0.047), lower hemoglobin on admission (p = 0.024), and the presence of diverticula (p = 0.002). Multivariate analysis indicated the presence of diverticula (p = 0.023) and male gender (p = 0.043) as rebleeding risk factors. DISCUSSION/CONCLUSION: In patients with hematochezia of unknown origin, risk factors for rebleeding indicated in this study, especially the presence of diverticula and male gender, should be given particular attention by physicians.

BACKGROUND & AIMS: Despite the significant advances made in the diagnosis and treatment of Barrett's esophagus (BE), there is still a need for standardized definitions, appropriate recognition of endoscopic landmarks, and consistent use of classification systems. Current controversies in basic definitions of BE and the relative lack of anatomic knowledge are significant barriers to uniform documentation. We aimed to provide consensus-driven recommendations for uniform reporting and global application. METHODS: The World Endoscopy Organization Barrett's Esophagus Committee appointed leaders to develop an evidence-based Delphi study. A working group of 6 members identified and formulated 23 statements, and 30 internationally recognized experts from 18 countries participated in 3 rounds of voting. We defined consensus as agreement by ≥80% of experts for each statement and used the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool to assess the quality of evidence and the strength of recommendations. RESULTS: After 3 rounds of voting, experts achieved consensus on 6 endoscopic landmarks (palisade vessels, gastroesophageal junction, squamocolumnar junction, lesion location, extraluminal compressions, and quadrant orientation), 13 definitions (BE, hiatus hernia, squamous islands, columnar islands, Barrett's endoscopic therapy, endoscopic resection, endoscopic ablation, systematic inspection, complete eradication of intestinal metaplasia, complete eradication of dysplasia, residual disease, recurrent disease, and failure of endoscopic therapy), and 4 classification systems (Prague, Los Angeles, Paris, and Barrett's International NBI Group). In round 1, 18 statements (78%) reached consensus, with 12 (67%) receiving strong agreement from more than half of the experts. In round 2, 4 of the remaining statements (80%) reached consensus, with 1 statement receiving strong agreement from 50% of the experts. In the third round, a consensus was reached on the remaining statement. CONCLUSIONS: We developed evidence-based, consensus-driven statements on endoscopic landmarks, definitions, and classifications of BE. These recommendations may facilitate global uniform reporting in BE.

BACKGROUND: Adult-onset Ménétrier's disease is strongly associated with Helicobacter pylori (H. pylori) infection and an elevated risk of carcinogenesis. Cases of early-stage gastric cancer developed in H. pylori-negative Ménétrier's disease are extremely rare. We report a case of early gastric cancer in H. pylori-negative Ménétrier's disease that was curatively resected with endoscopic submucosal dissection (ESD). CASE SUMMARY: A 60-year-old woman was referred to our hospital after her medical examination detected anemia. Contrast-enhanced upper gastrointestinal (UGI) radiography revealed translucency of the nodule-aggregating surface with giant rugae. Blood tests showed hypoproteinemia and were negative for serum H. pylori immunoglobulin G antibodies. The 99mTc-DTPA-human serum albumin scintigraphy showed protein loss from the stomach. UGI endoscopy showed a 40-mm protruding erythematous lesion on giant rugae of the greater curvature of lower gastric body, suggesting early-stage gastric cancer due to Ménétrier's disease. En bloc resection with ESD was performed for diagnosis and treatment. Histology of ESD showed well-differentiated tubular adenocarcinoma. The cancer was confined to the mucosa, and complete curative resection was achieved. Foveolar hyperplasia and atrophy of the gastric glands were observed in non-tumor areas, histologically corresponding to Ménétrier's disease. Three years after ESD, gastric cancer had not recurred, and Ménétrier's disease remained in remission with spontaneous regression of giant gastric rugae. CONCLUSION: Complete curative resection was achieved through ESD in a patient with early-stage gastric cancer and H. pylori-negative Ménétrier's disease.
