Abstract
Fever, abdominal pain, and liver dysfunction are almost inevitable complications of transcatheter arterial chemo embolization (TACE) for hepatocellular carcinoma, but these symptoms may also be due to bile duct obstruction caused by shedding of necrotic tumor material into the bile duct. A 68-year-old man presented with persistent fever, liver dysfunction, and abdominal pain after TACE. Computed tomography revealed stone-like hyperdensities in the bile duct. Endoscopic retrograde cholangiopancreatography revealed these structures to be necrotic material from hepatocellular carcinoma. We believe this is an instructive case of an often overlooked situation.

Abstract
BACKGROUND/AIMS Covered self-expandable metallic stents (cSEMS) have become popular for endoscopic ultrasound-guided hepaticogastrostomy with transmural stenting (EUS-HGS). We compared the time to recurrent biliary obstruction (TRBO), complications, and reintervention rates between EUS-HGS using plastic stent (PS) and cSEMS in patients with unresectable malignancies at multicenter institutions in Japan. METHODS Patients with unresectable malignant biliary obstruction who underwent EUS-HGS between April 2015 and July 2020 at any of the six participating facilities were enrolled. Primary endpoint: TRBO; secondary endpoints: rate of complications other than recurrent biliary obstruction and technical success rate of reintervention were evaluated. RESULTS PS and cSEMS were used for EUS-HGS in 109 and 43 patients, respectively. The TRBO was significantly longer in the cSEMS group than in the PS group (646 vs. 202 days). Multivariate analysis identified two independent factors associated with a favorable TRBO: combined EUS-guided antegrade stenting with EUS-HGS and the use of cSEMS. No significant difference was observed in the rate of complications other than recurrent biliary obstruction between the two groups. The technical success rate of reintervention was 85.7% for PS and 100% for cSEMS (p=0.309). CONCLUSION cSEMS might be a better option for EUS-HGS in patients with unresectable malignancies, given the longer TRBO.

Abstract
A 66-year-old woman who had been suffering from chronic anorexia for two years was transported to the hospital after being unable to consume food for three days. She had no hematemesis or abdominal pain and had no history of taking nonsteroidal anti-inflammatory drugs. Blood tests showed marked anemia with hemoglobin of 3.3 g/dL, and esophagogastroduodenoscopy revealed a large ulcer lesion in the lesser curvature of the gastric body and a liver-like mass protruding from the ulcer base. Biopsy of the mass showed proliferation of cells showing irregular cord-like structures, suggestive of normal liver tissue or hepatocellular carcinoma. Computed tomography scan showed no obvious free air in the abdomen. Despite conservative treatment, the patient developed hematemesis and progressive anemia, and surgery was performed (total gastrectomy with partial hepatectomy). Surgical specimen showed an ulcer lesion with fibrosis and loss of wall structure in all layers of the stomach, and liver adhesion with fibrosis deep in the ulcer, but no malignant findings. With the advent of powerful gastric acid secretion inhibitors, gastric ulcer invasion into the liver is now very rare, and this case is thus a valuable example showing very clear images.

Abstract
A 70-year-old Japanese man with a submucosal gastric mass that continued to increase in size underwent endoscopic submucosal dissection using the pocket creation method. Histologically, some epithelial cell nuclei were enlarged, but there was little atypia overall and no sign of malignancy, suggesting a diagnosis of submucosal heterotopic gastric gland (SHGG). SHGG that enlarges over time has been associated with gastric cancer, but a preoperative diagnosis is difficult. This case was very valuable, as it enabled us to follow the course of SHGG over a period of about nine years, from the onset to enlargement.

Abstract
BACKGROUND We have previously demonstrated that the first wave of the coronavirus disease 2019 (COVID-19) pandemic caused exacerbations in ulcerative colitis (UC) patients, probably through psychological and physical stress. However, successive waves of the COVID-19 pandemic continuously followed the first. The effects of this chronic stress on the disease condition in UC patients are of interest. AIM To clarify the effect of chronic stress from COVID-19 on disease condition in patients aggravated after the first wave. METHODS Our previous study investigated 289 consecutive UC outpatients treated in one center during March and April 2020, the period of the first wave of the COVID-19 pandemic. In this study, an identical group of 289 UC patients was evaluated using UC-disease activity index (UC-DAI), endoscopic mucosal appearance score, and Matts pathological grade scoring. RESULTS Of the 289 UC patients included in the study in 2020, 10 patients dropped out as of 2021 and another 11 patients dropped out as of 2022, making three groups for 2020, 2021 and 2022. No significant differences in characteristics were found among the three groups. UC-DAI scores had aggravated during the period of the first wave of the COVID-19 pandemic, but significantly recovered in 2021 and remained stable in 2022. Matts grade scores significantly recovered in 2021 from those in 2020 and remained stable in 2022. CONCLUSION Disease activity of UC patients recovered in 2021 and remained stable in 2022, aggravated by the stress of the first wave of COVID-19 in 2020 despite persistence of the pandemic.

Abstract
Eosinophilic pancreatitis (EP) is very rare and characterised by infiltration of eosinophils into the pancreatic parenchyma. A 40-year-old man was diagnosed with total-colitis-type ulcerative colitis at the age of 15 years. He was then diagnosed with steroid-dependent ulcerative colitis. He was given golimumab, which resulted in remission. Ten months after beginning golimumab, he was urgently hospitalised with a diagnosis of acute pancreatitis. Hence, endoscopic ultrasound-guided fine needle biopsy was performed to obtain a definitive diagnosis. Pathologically, abundant infiltration of eosinophils was observed in the edematous intralobular stroma of the pancreas. He was diagnosed with EP, and treated with corticosteroids.

Abstract
Objectives In recent years, endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) has been performed as an important salvage option for failed endoscopic retrograde cholangiopancreatography for biliary drainage. However, technical issues, such as puncture site (bile duct of segment 3 [B3] or bile duct of segment 2 [B2]), dilation method, stent selection, and procedural safety, need to be resolved for the optimization of EUS-HGS. The present study was to compare the safety, difficulty, and technical and functional success between biliary access via B2 and B3 during EUS-HGS. Methods We conducted a retrospective investigation of 161 consecutive EUS-HGS cases across a total of 6 facilities, including those at our hospital. The patients were divided into two groups according to the successful drainage route: the puncture to B2 (P-B2) or the puncture to B3 (P-B3). We compared the technical and functional success rates, technical difficulty, and adverse events between the two groups. We also conducted a subgroup analysis to show the factors related to the procedure time. Results There were 92 cases in the P-B2 group and 69 cases in the P-B3 group. There were no significant differences in the technical success, functional success, or adverse events between the groups; however, the procedure time was significantly shorter in P-B2 cases than in P-B3 cases. The multivariate analysis showed that the puncture site was the only factor related to the procedure time. Conclusions Based on these findings, P-B2 appears useful and safe. P-B2 is as effective as P-B3 and was able to be performed in a shorter period of time. The B2 approach can be considered a useful option for EUS-HGS.

Abstract
Objectives Early obstruction of a self‐expandable metal stent placed for distal malignant biliary obstruction is more likely to occur in the presence of duodenal invasion. An anti‐reflux self‐expandable metal stent (ARMS) has been developed for the purpose of preventing duodenal fluid reflux into the bile duct. In this study, we evaluated the usefulness and safety of a duckbill‐type ARMS (D‐ARMS) in the situation of duodenal invasion. Methods We retrospectively analyzed 10 consecutive patients who received D‐ARMS for distal malignant biliary obstruction with duodenal invasion. We evaluated non‐occlusion cholangitis, recurrent biliary obstruction (RBO), and adverse events after D‐ARMS placement. Results There were no cases of non‐occlusion cholangitis. RBO was observed in 2 patients (20%), and time to RBO was 236 days and 117 days, respectively. The causes of RBO were overgrowth and sludge formation. The median time to RBO was 382 days (range, 117–382 days). Only one adverse event was observed (cholecystitis). Conclusions D‐ARMS shows potential as an optimal ARMS.

Abstract
Background and Aim Based on past diagnostic classifications of gastritis, the Kyoto classification of gastritis adopts simpler, more objective gastritis findings according to Helicobacter pylori infection status and evaluates the risk of gastric cancer. To clarify whether this score can predict future gastric cancer, we retrospectively examined risk scores obtained using the Kyoto classification of gastritis a few years prior to the diagnosis of early gastric cancer. Methods We reviewed data from 50 individuals who had undergone upper gastrointestinal endoscopy 2–3 years prior to the diagnosis of early gastric cancer in our hospital. Two expert endoscopists evaluated and compared risk scores obtained using the Kyoto classification of gastritis between cancer and control groups. Results With regard to the risk score obtained using the Kyoto classification of gastritis in all cases, atrophy, intestinal metaplasia, diffuse redness, and total score were significantly higher among gastric cancer cases. Among H. pylori‐eradicated cases, atrophy score was higher in the gastric cancer group. Among patients for whom H. pylori had been eradicated for >3 years at first endoscopy, atrophy score was still higher in the gastric cancer group. Conclusion This retrospective study suggested that the risk score obtained using the Kyoto classification of gastritis was useful for predicting the onset of gastric cancer. In particular, patients with a high atrophy score even after H. pylori eradication may be at high risk of developing gastric cancer.

Abstract
A 43-year-old Japanese man diagnosed with Cronkhite-Canada Syndrome (CCS) underwent endoscopic submucosal dissection for Helicobacter pylori-negative gastric cancer. Histologically, the completely resected specimen showed large and small irregular glands composed of foveolar epithelial-like atypical cells, and it was immunohistochemically MUC5AC positive overall, MUC6 positive except for the surface layer and nearby parts, and MUC2 negative. The patient was diagnosed with gastric-phenotype, low-grade, well-differentiated adenocarcinoma. This is a case of gastric cancer developing in CCS definitively without H. pylori infection. We conclude that H. pylori infection is not an absolute condition in gastric cancer associated with CCS. Elucidation of the true malignant potential of CCS excluding the effects of H. pylori infection is needed.

Abstract
Objective Colonic diverticular bleeding often recurs, and readmissions are common. The aim of this study was to identify predictors of colonic diverticular recurrent bleeding and readmission within 90 days. Methods Subjects comprised 144 patients diagnosed with colonic diverticular bleeding who received inpatient hospital care between January 2012 and June 2017. A retrospective comparative study was carried out regarding the clinical characteristics during the hospital stay by dividing the cases into 2 groups: patients with recurrent bleeding requiring readmission within 90 days (n=17) and patients without recurrent bleeding (n=127). Results A univariate analysis showed that recurrent bleeding and readmission were significantly more frequent among cases with hypovolemic shock on admission (p=0.009), blood transfusion during hospitalization (p=0.029), and hyperlipidemia (p=0.020) than among others. Shock on admission (odds ratio, 5.118; 95% confidence interval, 1.168-22.426, p=0.030) remained a significant predictor on a multivariate analysis. Conclusion Shock may predict recurrent colonic diverticular bleeding and readmission within 90 days. Careful and adequate endoscopic hemostasis is recommended for patients showing shock on admission.

Abstract
Esophagogastroduodenoscopy of a 45-year-old woman revealed a submucosal tumor in the gastric antrum. Endoscopic submucosal dissection of the tumor was performed. The histological findings revealed a fibromyxomatous tumor composed of myofibroblastic cells with no evidence of malignancy. The growth pattern of the resected specimen was not multinodular or plexiform. We therefore tentatively referred to the present tumor descriptively as a gastric uninodular fibromyxomatous tumor, stressing its singular nodularity. It was initially roughly 10 mm in size but grew over a period of 4 years. A uninodular plexiform fibromyxoma might increase in size but might not become multinodular if it remains small.

Abstract
Purpose Pancreatic/gastrointestinal tract neuroendocrine neoplasm (NEN) is divided into neuroendocrine tumor (NET) and neuroendocrine carcinoma (NEC) according to the grade of malignancy, and differences are seen in clinical prognosis. NET, and rectal NET in particular, is often treated endoscopically. Endoscopic mucosal resection (EMR) was previously the main intervention for rectal NET, but EMR with a ligation device (EMR-L) and endoscopic submucosal dissection (ESD) are now also used. However, complete resection with these therapies is not always achieved. The pocket creation method (PCM) is a safe ESD method for colon tumors that offers a high en bloc resection rate compared with conventional colonic ESD. We performed ESD using the PCM for rectal NET and evaluated the complete resection rate. Methods We performed ESD using the PCM in 4 patients. This procedure was technically feasible in all patients. Results Endoscopically, all cases were resected en bloc, and pathological complete resection was achieved in all cases. No complications such as perforation or delayed postoperative bleeding were encountered. Conclusions PCM should be considered when treating NET of appropriate size.

Abstract
Immunoglobulin G4-related disease (IgG4-RD) represents a group of disorders that share features of inflammation, plasma cell infiltrates, and fibrosis. Sclerosing cholangitis is a disorder involving inflammation, scarring, and destruction of the bile ducts. IgG4-related sclerosing cholangitis (IgG4-SC) has been proposed as a bile duct lesion associated with IgG4-RD. This disease entity can be distinguished from other types of sclerosing cholangitis and classified into four types based upon the region of strictures revealed by cholangiography. Here, we present two cases in which the finding of bile duct wall thickening visualized with transabdominal ultrasonography was useful in the diagnosis of patients with IgG4-SC. At present, transabdominal ultrasonography is not included in the diagnostic algorithm for IgG4-SC. We are certain that detailed observation of the bile duct wall with transabdominal ultrasonography can make a significant contribution to the diagnosis of IgG4-SC. Furthermore, we propose that transabdominal ultrasonography may be useful in following clinical improvement in cases where a steroid trial is the best option for treatment. Both cases emphasize the practicality of transabdominal ultrasonography in the diagnosis and follow-up observation of IgG4-SC.

Abstract
The same iron pot in which their father had boiled lead with mercury (from a glass thermometer) for the purpose of alchemy, was also used for cooking in the kitchen. Although his wife had died of mercury poisoning, and his 14-year-old and 11-year-old daughters were found to excrete 322 and 455 micrograms/l mercury in the urine, respectively, (1-10 micrograms/l in controls), he stubbornly refused to give permission for them to be examined further. Nine months later, the daughters were permitted to be sent to our clinical ward. While the blood level of mercury had already come down to near normal, its excessive deposition in hair, kidneys and other parts of the body as well as its excessive urinary excretion, were still persistent (beyond tenfold the normal). According to our measurement values, mercury ranged from 14 to 49 micrograms/g in every 1-cm-piece of 10 cm hair of the elder sister, and ranged from 21 to 85 micrograms/g in 14 cm hair from the younger sister. About a 75% decrease in mercury deposition was estimated during these 9 months, based on the speculation of 1.5 cm/month hair-lengthening.
