BACKGROUND Duodenal Brunner's gland hyperplasia(BGH)is a therapeutic target when complications such as bleeding or gastrointestinal obstruction occur or when malignancy cannot be ruled out.Herein,we present a case of large BGH treated with endoscopic mucosal resection(EMR).CASE SUMMARY An 83-year-old woman presented at our hospital with dizziness.Blood tests revealed severe anemia,esophagogastroduodenoscopy showed a 6.5 cm lesion protruding from the anterior wall of the duodenal bulb,and biopsy revealed the presence of glandular epithelium.Endoscopic ultrasonography(EUS)demonstr-ated relatively high echogenicity with a cystic component.The muscularis propria was slightly elevated at the base of the lesion.EMR was performed without complications.The formalin-fixed lesion size was 6 cm×3.5 cm×3 cm,showing nodular proliferation of non-dysplastic Brunner's glands compartmentalized by fibrous septa,confirming the diagnosis of BGH.Reports of EMR or hot snare polypectomy are rare for duodenal BGH>6 cm.In this case,the choice of EMR was made by obtaining information on the base of the lesion as well as on the internal characteristics through EUS.CONCLUSION Large duodenal lesions with good endoscopic maneuverability and no evident muscular layer involvement on EUS may be resectable via EMR. 展开更多

Pancreatic ductal adenocarcinoma is speculated to become the second leading cause of cancer-related mortality by 2030,a high mortality rate considering the number of cases.Surgery and chemotherapy are the main treatment options,but they are burdensome for patients.A clear histological diagnosis is needed to determine a treatment plan,and endoscopic ultrasound(EUS)-guided tissue acquisition(TA)is a suitable technique that does not worsen the cancer-specific prognosis even for lesions at risk of needle tract seeding.With the development of personalized medicine and precision treatment,there has been an increasing demand to increase cell counts and collect specimens while preserving tissue structure,leading to the development of the fine-needle biopsy(FNB)needle.EUS-FNB is rapidly replacing EUS-guided fine-needle aspiration(FNA)as the procedure of choice for EUS-TA of pancreatic cancer.However,EUS-FNA is sometimes necessary where the FNB needle cannot penetrate small hard lesions,so it is important clinicians are familiar with both.Given these recent developments,we present an up-to-date review of the role of EUS-TA in pancreatic cancer.Particularly,technical aspects,such as needle caliber,negative pressure,and puncture methods,for obtaining an adequate specimen in EUS-TA are discussed. 展开更多

Common bile duct stones are among the most common conditions encountered by endoscopists.Therefore,it is well researched;however,some items,such as indications for endoscopic papillary balloon dilatation(EPBD),safety of EPBD and endoscopic sphincterotomy in patients receiving dual antiplatelet therapy or direct oral anticoagulant,selection strategy for retrieval balloons and baskets,lack adequate evidence.Therefore,the guidelines have been updated with new research,while others remain unchanged due to weak evidence.In this review,we comprehensively summarize the standard methods in guidelines and new findings from recent studies on papillary dilation,stone retrieval devices,difficult-to-treat cases,troubleshooting during the procedure,and complicated cases of cholangitis,cholecystolithiasis,or distal biliary stricture. 展开更多

BACKGROUND Ischemic gastritis is a clinically rare and highly fatal disease that occurs when the hemodynamics of a patient with vascular risk is disrupted.Early diagnosis and treatment are possible only with upper endoscopy after symptom appearance.We report seven cases of ischemic gastritis and its clinical features,prognosis,and indicators that may help in early detection.CASE SUMMARY Of the seven patients,six had vascular risk and five died within 2 wk of diagnosis.Their symptoms included hematemesis and hypotension.Although surgery is a choice for radical treatment,not all patients were tolerant.For such patients,conservative treatment was selected,but all of them died.In contrast,patients who underwent repeat endoscopy showed improved mucosal findings,suggesting that this improvement may not affect prognosis.Some ischemic changes such as wall thickening,mural emphysema,and fluid retention in the stomach were observed before diagnosis through endoscopy and computed tomography(CT).The CT scan can be effective for early detection,and improvement in circulatory failure and aggressive treatment may save the lives of patients with this disease.CONCLUSION The characteristic CT findings enable early detection of ischemic gastritis.Early diagnosis increases the chance of survival if early therapeutic intervention and improvement of circulatory dynamics can be achieved in this highly fatal disease. 展开更多

BACKGROUND Current guidelines recommend colonoscopy within 24 h for acute lower gastrointestinal bleeding;however,the evidence in support for colonic diverticular hemorrhage(CDH)indications remains insufficient.AIM To investigate the effectiveness of early colonoscopy on the length of hospital stay for CDH patients.METHODS We conducted a single-center retrospective cohort study.Patients who underwent colonoscopy within 24 h of presentation(early group)were compared with those who underwent colonoscopy beyond 24 h of presentation(elective group).The primary outcome was the length of hospital stay,and secondary outcomes were the identification of stigmata of recent hemorrhage(SRH),rebleeding,red blood cell transfusion more than 4 units,and interventional radiology and abdominal surgery after colonoscopy.RESULTS We identified 574 CDH cases.Patients were divided into the early(n=328)and elective(n=226)groups.After propensity score matching,191 pairs were generated.The length of hospital stay did not significantly differ between the two groups(early group vs elective group;median,7 vs 8 d;P=0.10).The early group had a significantly high identification of SRH(risk difference,11.6%;95%CI:2.7 to 20.3;P=0.02).No significant differences were found in the rebleeding(risk difference,4.7%;95%CI:-4.1 to 13.5;P=0.35),red blood cell transfusion more than 4 units(risk difference,1.6%;95%CI:-7.5 to 10.6;P=0.82),and interventional radiology and abdominal surgery rate after colonoscopy(risk difference,0.5%;95%CI:-2.2 to 3.2;P=1.00).CONCLUSION Early colonoscopy within 24 h,on arrival for CDH,could not improve the length of hospital stay. 展开更多
