文摘In this editorial,we respond to a review article by Nabi et al,in which the authors discussed gastroesophageal reflux(GER)following peroral endoscopic myotomy(POEM).POEM is presently the primary therapeutic option for achalasia,which is both safe and effective.A few adverse effects were documented after POEM,including GER.The diagnostic criteria were not clear enough because approximately 60%of patients have a long acid exposure time,while only 10%experience reflux symptoms.Multiple predictors of high disease incidence have been identified,including old age,female sex,obesity,and a baseline lower esophageal sphincter pressure of less than 45 mmHg.Some technical steps during the procedure,such as a lengthy or full-thickness myotomy,may further enhance the risk.Proton pump inhibitors are currently the first line of treatment.Emerging voices are increasingly advocating for the routine combining of POEM with an endoscopic fundoplication method,such as peroral endoscopic fundoplication or transoral incisionless fundoplication.However,more research is necessary to determine the safety and effectiveness of these procedures in the long term for patients who have undergone them.
文摘Achalasia cardia,the most prevalent primary esophageal motility disorder,is predominantly characterized by symptoms of dysphagia and regurgitation.The principal therapeutic approaches for achalasia encompass pneumatic dilatation(PD),Heller's myotomy,and the more recent per-oral endoscopic myotomy(POEM).POEM has been substantiated as a safe and efficacious modality for the management of achalasia.Although POEM demonstrates superior efficacy compared to PD and an efficacy parallel to Heller's myotomy,the incidence of gastroesophageal reflux disease(GERD)following POEM is notably higher than with the aforementioned techniques.While symptomatic reflux post-POEM is relatively infrequent,the significant occurrence of erosive esophagitis and heightened esophageal acid exposure necessitates vigilant monitoring to preclude long-term GERD-related complications.Contemporary advancements in the field have enhanced our comprehension of the risk factors,diagnostic methodologies,preventative strategies,and therapeutic management of GERD subsequent to POEM.This review focuses on the limitations inherent in the 24-h pH study for evaluating post-POEM reflux,potential modifications in the POEM technique to mitigate GERD risk,and the strategies for managing reflux following POEM.
文摘This narrative review provides an overview of the utilization of endoscopic ultrasound-guided gallbladder drainage(EUS-GBD)as a salvage approach in cases of unsuccessful conventional management.EUS-GBD is a minimally invasive and effective technique for drainage in patients with acute cholecystitis with high risk of surgery.The procedure has demonstrated impressive technical and clinical success rates with low rates of adverse events,making it a safe and effective option for appropriate candidates.Furthermore,EUS-GBD can also serve as a rescue option for patients who have failed endoscopic retrograde cholangiopancreatography or EUS biliary drainage for relief of jaundice in malignant biliary stricture.However,patient selection is critical for the success of EUS-GBD,and proper patient selection and risk assessment are important to ensure the safety and efficacy of the procedure.As the field continues to evolve and mature,ongoing research will further refine our understanding of the benefits and limitations of EUS-GBD,ultimately leading to improved outcomes for patients.

文摘The increasing popularity of endoscopic submucosal dissection(ESD)as a treatment for early gastric cancer has highlighted the importance of quality assessment in achieving curative resections.This article emphasizes the significance of evaluating ESD quality,not only for curative cases but also for non-curative ones.Postoperative assessment relies on the endoscopic curability(eCura)classification,but management strategies for eCuraC-1 tumour with a positive horizontal margin are unclear.Current research primarily focuses on comparing additional surgical procedures in high-risk patients,while studies specifically targeting eCuraC-1 patients are limited.Exploring management strategies and follow-up outcomes for such cases could provide valuable insights.Furthermore,the application of molecular imaging using near-infrared fluorescent tracers holds promise for precise tumour diagnosis and navigation,potentially impacting the management of early-stage gastric cancer patients.Advancing research in these areas is essential for improving the overall efficacy of endoscopic techniques and refining treatment indications.
文摘BACKGROUND Endoscopic submucosal dissection(ESD)and transanal endoscopic submucosal dissection(TES)are widely employed surgical techniques.However,the comparative efficacy and safety of both remain inconclusive.AIM To comprehensively analyze and discern differences in surgical outcomes between ESD and TES.METHODS We conducted a systematic search of the electronic databases PubMed,Embase,Cochrane Central Register of Controlled Trials,Scopus,and CINAHL from inception till August 2023.We analyzed outcomes including recurrence rate,en bloc resection,R0 resection rate,perforation rate,procedure length,and hospital stay length applying a random-effects inverse-variance model.We assessed publication bias by conducting an Egger’s regression test and sensitivity analyses.RESULTS We pooled data from 11 studies involving 1013 participants.We found similar recurrence rates,with a pooled odds ratio of 0.545(95%CI:0.176-1.687).En bloc resection,R0 resection,and perforation rate values were also similar for both ESD and TES.The pooled analysis for procedure length indicated a mean difference of-4.19 min(95%CI:-22.73 to 14.35),and the hospital stay was on average shorter for ESDs by about 0.789 days(95%CI:-1.671 to 0.093).CONCLUSION Both ESD and TES displayed similar efficacy and safety profiles across multiple outcomes.Our findings show that individualized patient and surgeon preferences,alongside specific clinical contexts,can be considered when selecting between these two techniques.
文摘This editorial is an analysis the review article by Nabi et al recently published in this journal.Achalasia Cardia is a disease whose pathophysiology is still unclear.It is known that there is inflammation of unknown aetiology leading to loss of ganglion cells in the muscularis propria.The end result is lower oesophageal sphincter spasm,loss of receptive relaxation,decreased oesophageal peristalsis,all leading on to varying degrees of dysphagia.The treatment of this condition is palliative in nature,performed by myotomy of the lower oesophagus either surgically or endoscopically.Gastroesophageal reflux disease(GERD)has been associated with the myotomy performed,particularly with the Peroral Endoscopic Myotomy(POEM)procedure.Nabi et al have provided an excellent overview of the latest developments in predicting,preventing,evaluating,and managing GERD subsequent to POEM.Based on this theme,this review article explores the concept of using histology of the oesophageal muscle layer,to grade the disease and thereby help tailoring the length/type of myotomy performed during the POEM procedure.In the future,will a histology based algorithm available preoperatively,help modify the POEM procedure,thereby decreasing the incidence of GERD associated with POEM?

文摘BACKGROUND Guidewire slippage into the peritoneal cavity during clinical operations is extremely rare.Therefore,this paper aims to report a successful case of guidewire removal using transgastric natural orifice transluminal endoscopic surgery(NOTES).The goal is to enhance physicians'understanding of the management plan for this unique scenario and provide a valuable reference for clinical practice.CASE SUMMARY A 64-year-old man presented with abdominal distension and was diagnosed with cirrhosis combined with massive ascites.To proceed with treatment,the patient underwent ultrasound-guided peritoneal puncture and underwent catheterization and drainage.Unfortunately,a 0.035-inch guidewire slipped into the abdominal cavity during the procedure.Following a comprehensive evaluation and consultation by a multidisciplinary team,the guidewire was successfully removed using NOTES.CONCLUSION This case highlights the potential consideration of transgastric NOTES removal when encountering a foreign body,such as a guidewire,within the abdominal cavity.
文摘Contrast-enhanced endoscopic ultrasound(CH-EUS)can overcome the limi-tations of endoscopic ultrasound-guided acquisition by identifying microvessels inside inhomogeneous tumours and improving the characterization of these tumours.Despite the initial enthusiasm that oriented needle sampling under CH-EUS guidance could provide better diagnostic yield in pancreatic solid lesions,further studies did not confirm the supplementary values in cases of tissue acquisition guided by CH-EUS.This review details the knowledge based on the available data on contrast-guided procedures.The indications for CH-EUS tissue acquisition include isoechoic EUS lesions with poor visible delineation where CH-EUS can differentiate the lesion vascularisation from the surrounding parenchyma and also the mural nodules within biliopancreatic cystic lesions,which occur in select cases.Additionally,the roles of CH-EUS-guided therapy in patients whose pancreatic fluid collections or bile ducts that have an echogenic content have indications for drainage,and patients who have nonvisualized vessels that need to be highlighted via Doppler EUS are presented.Another indication is represented if there is a need for an immediate assessment of the post-radiofrequency ablation of pancreatic neuroendocrine tumours,in which case CH-EUS can be used to reveal the incomplete tumour destruction.
文摘BACKGROUND Gastric stromal tumors,originating from mesenchymal tissues,are one of the most common tumors of the digestive tract.For stromal tumors originating from the muscularis propria,compared with conventional endoscopic submucosal dissection(ESD),endoscopic full-thickness resection(EFTR)can remove deep lesions and digestive tract wall tumors completely.However,this technique has major limitations such as perforation,postoperative bleeding,and post-polypectomy syndrome.Herein,we report a case of postoperative serous surface bleeding which formed an encapsulated hemoperitoneum in a patient with gastric stromal tumor that was treated with exposed EFTR.Feasible treatment options to address this complication are described.CASE SUMMARY A 47-year-old male patient had a hemispherical protrusion found during gastric endoscopic ultrasonography,located at the upper gastric curvature adjacent to the stomach fundus,with a smooth surface mucosa and poor mobility.The lesion was 19.3 mm×16.1 mm in size and originated from the fourth ultrasound layer.Computed tomography(CT)revealed no significant evidence of lymph node enlargement or distant metastasis.Using conventional ESD technology for mucosal pre-resection,exposed EFTR was performed to resect the intact tumor in order to achieve a definitive histopathological diagnosis.Based on its morphology and immunohistochemical expression of CD117 and DOG-1,the lesion was proven to be consistent with a gastric stromal tumor.Six days after exposed EFTR,CT showed a large amount of encapsulated fluid and gas accumulation around the stomach.In addition,gastroscopy suggested intracavitary bleeding and abdominal puncture drainage indicated serosal bleeding.Based on these findings,the patient was diagnosed with serosal bleeding resulting in encapsulated abdominal hemorrhage after exposed EFTR for a gastric stromal tumor.The patient received combined treatments,such as hemostasis under gastroscopy,gastrointestinal decompression,and abdominal drainage.All examinations were normal within six months of follow-up.CONCLUSION This patient developed serous surface bleeding in the gastric cavity following exposed EFTR.Serosal bleeding resulting in an encapsulated hemoperitoneum is rare in clinical practice.The combined treatment may replace certain surgical techniques.

文摘BACKGROUND Endoscopic evaluation in diagnosing and managing ulcerative colitis(UC)is becoming increasingly important.Several endoscopic scoring systems have been established,including the Ulcerative Colitis Endoscopic Index of Severity(UCEIS)score and Mayo Endoscopic Subscore(MES).Furthermore,the Toronto Inflammatory Bowel Disease Global Endoscopic Reporting(TIGER)score for UC has recently been proposed;however,its clinical value remains unclear.AIM To investigate the clinical value of the TIGER score in UC by comparing it with the UCEIS score and MES.METHODS This retrospective study included 166 patients with UC who underwent total colonoscopy between January 2017 and March 2023 at the Affiliated Hospital of Qingdao University(Qingdao,China).We retrospectively analysed endoscopic scores,laboratory and clinical data,treatment,and readmissions within 1 year.Spearman’s rank correlation coefficient,receiver operating characteristic curve,and univariate and multivariable logistic regression analyses were performed using IBM SPSS Statistics for Windows,version 26.0(IBM Corp.,Armonk,NY,United States)and GraphPad Prism version 9.0.0 for Windows(GraphPad Software,Boston,Massachusetts,United States).RESULTS The TIGER score significantly correlated with the UCEIS score and MES(r=0.721,0.626,both P<0.001),showed good differentiating values for clinical severity among mild,moderate,and severe UC[8(4-112.75)vs 210(109–219)vs 328(219–426),all P<0.001],and exhibited predictive value in diagnosing patients with severe UC[area under the curve(AUC)=0.897,P<0.001].Additionally,the TIGER(r=0.639,0,551,0.488,0.376,all P<0.001)and UCEIS scores(r=0.622,0,540,0.494,and 0.375,all P<0.001)showed stronger correlations with laboratory and clinical parameters,including C-reactive protein,erythrocyte sedimentation rate,length of hospitalisation,and hospitalisation costs,than MES(r=0.509,0,351,0.339,and 0.270,all P<0.001).The TIGER score showed the best predictability for patients'recent advanced treatment,including systemic corticosteroids,biologics,or immunomodulators(AUC=0.848,P<0.001)and 1-year readmission(AUC=0.700,P<0.001)compared with the UCEIS score(AUC=0.762,P<0.001;0.627,P<0.05)and MES(AUC=0.684,P<0.001;0.578,P=0.132).Furthermore,a TIGER score of≥317 was identified as an independent risk factor for advanced UC treatment(P=0.011).CONCLUSION The TIGER score may be superior to the UCIES score and MES in improving the accuracy of clinical disease severity assessment,guiding therapeutic decision-making,and predicting short-term prognosis.
文摘BACKGROUND In hepatology,the clinical use of endoscopic ultrasound(EUS)has experienced a notable increase in recent times.These applications range from the diagnosis to the treatment of various liver diseases.Therefore,this systematic review summarizes the evidence for the diagnostic and therapeutic roles of EUS in liver diseases.AIM To examine and summarize the current available evidence of the possible roles of the EUS in making a suitable diagnosis in liver diseases as well as the therapeutic accuracy and efficacy.METHODS PubMed,Medline,Cochrane Library,Web of Science,and Google Scholar databases were extensively searched until October 2023.The methodological quality of the eligible articles was assessed using the Newcastle-Ottawa scale or Cochrane Risk of Bias tool.In addition,statistical analyses were performed using the Comprehensive Meta-Analysis software.RESULTS Overall,45 articles on EUS were included(28 on diagnostic role and 17 on therapeutic role).Pooled analysis demonstrated that EUS diagnostic tests had an accuracy of 92.4%for focal liver lesions(FLL)and 96.6%for parenchymal liver diseases.EUS-guided liver biopsies with either fine needle aspiration or fine needle biopsy had low complication rates when sampling FLL and parenchymal liver diseases(3.1%and 8.7%,respectively).Analysis of data from four studies showed that EUS-guided liver abscess had high clinical(90.7%)and technical success(90.7%)without significant complications.Similarly,EUS-guided interventions for the treatment of gastric varices(GV)have high technical success(98%)and GV obliteration rate(84%)with few complications(15%)and rebleeding events(17%).CONCLUSION EUS in liver diseases is a promising technique with the potential to be considered a first-line therapeutic and diagnostic option in selected cases.

文摘BACKGROUND According to practice guidelines,endoscopic band ligation(EBL)and endoscopic tissue adhesive injection(TAI)are recommended for treating bleeding from esophagogastric varices.However,EBL and TAI are known to cause serious complications,such as hemorrhage from dislodged ligature rings caused by EBL and hemorrhage from operation-related ulcers resulting from TAI.However,the optimal therapy for mild to moderate type 1 gastric variceal hemorrhage(GOV1)has not been determined.Therefore,the aim of this study was to discover an individualized treatment for mild to moderate GOV1.AIM To compare the efficacy,safety and costs of EBL and TAI for the treatment of mild and moderate GOV1.METHODS A clinical analysis of the data retrieved from patients with mild or moderate GOV1 gastric varices who were treated under endoscopy was also conducted.Patients were allocated to an EBL group or an endoscopic TAI group.The differences in the incidence of varicose relief,operative time,operation success rate,mortality rate within 6 wk,rebleeding rate,6-wk operation-related ulcer healing rate,complication rate and average operation cost were compared between the two groups of patients.RESULTS The total effective rate of the two treatments was similar,but the efficacy of EBL(66.7%)was markedly better than that of TAI(39.2%)(P<0.05).The operation success rate in both groups was 100%,and the 6-wk mortality rate in both groups was 0%.The average operative time(26 min)in the EBL group was significantly shorter than that in the TAI group(46 min)(P<0.01).The rate of delayed postoperative rebleeding in the EBL group was significantly lower than that in the TAI group(11.8%vs 45.1%)(P<0.01).At 6 wk after the operation,the healing rate of operation-related ulcers in the EBL group was 80.4%,which was significantly greater than that in the TAI group(35.3%)(P<0.01).The incidence of postoperative complications in the two groups was similar.The average cost and other related economic factors were greater for the EBL than for the TAI(P<0.01).CONCLUSION For mild to moderate GOV1,patients with EBL had a greater one-time varix eradication rate,a greater 6-wk operation-related ulcer healing rate,a lower delayed rebleeding rate and a lower cost than patients with TAI.
文摘Background:To prevent stent migration during endoscopic ultrasound-guided hepaticogastrostomy(EUS-HGS),intra-scope channel release technique is important,but is unfamiliar to non-expert hands.The self-expandable metal stent(SEMS)is an additional factor to prevent stent migration.However,no compara-tive studies of laser-cut-type and braided-type during EUS-HGS have been reported.The aim of this study was to compare the distance between the intrahepatic bile duct and stomach wall after EUS-HGS among laser-cut-type and braided-type SEMS.Methods:To evaluate stent anchoring function,we measured the distance between the hepatic parenchyma and stomach wall before EUS-HGS,one day after EUS-HGS,and 7 days after EUS-HGS.Also,propensity score matching was performed to create a propensity score for using laser-cut-type group and braided-type group.Results:A total of 142 patients were enrolled in this study.Among them,24 patients underwent EUS-HGS using a laser-cut-type SEMS,and 118 patients underwent EUS-HGS using a braided-type SEMS.EUS-HGS using the laser-cut-type SEMS was mainly performed by non-expert endoscopists(n=21);EUS-HGS using braided-type SEMS was mainly performed by expert endoscopists(n=98).The distance after 1 day was significantly shorter in the laser-cut-type group than that in the braided-type group[2.00(1.70-3.75)vs.6.90(3.72-11.70)mm,P<0.001].In addition,this distance remained significantly shorter in the laser-cut-type group after 7 days.Although these results were similar after propensity score matching analysis,the distance between hepatic parenchyma and stomach after 7 days was increased by 4 mm compared with the distance after 1 day in the braided-type group.On the other hand,in the laser-cut-type group,the distance after 1 day and 7 days was almost the same.Conclusions:EUS-HGS using a laser-cut-type SEMS may be safe to prevent stent migration,even in non-expert hands.
文摘The combination of endoscopic ultrasound with endoscopic treatment of type 1 gastric variceal hemorrhage may improve the robustness and generalizability of the findings in future studies.Moreover,the esophageal varices should also be included in the evaluation of treatment efficacy in subsequent studies to reach a more convincing conclusion.
文摘BACKGROUND Infected acute necrotic collection(ANC)is a fatal complication of acute pancre-atitis with substantial morbidity and mortality.Drainage plays an exceedingly important role as the first step in invasive intervention for infected necrosis;however,there is great controversy about the optimal drainage time,and better treatment should be explored.CASE SUMMARY We report the case of a 43-year-old man who was admitted to the hospital with severe intake reduction due to early satiety 2 wk after treatment for acute pancre-atitis;conservative treatment was ineffective,and a pancreatic pseudocyst was suspected on contrast-enhanced computed tomography(CT).Endoscopic ultra-sonography(EUS)suggested hyperechoic necrotic tissue within the cyst cavity.The wall was not completely mature,and the culture of the puncture fluid was positive for A-haemolytic Streptococcus.Thus,the final diagnosis of ANC in-fection was made.The necrotic collection was not walled off and contained many solid components;therefore,the patient underwent EUS-guided aspiration and lavage.Two weeks after the collection was completely encapsulated,pancreatic duct stent drainage via endoscopic retrograde cholangiopancreatography(ERCP)was performed,and the patient was subsequently successfully discharged.On repeat CT,the pancreatic cysts had almost disappeared during the 6-month fo-llow-up period after surgery.CONCLUSION Early EUS-guided aspiration and lavage combined with late ERCP catheter drainage may be effective methods for intervention in infected ANCs.
文摘●AIM:To compare the success rate and complications of adjuvant use of mitomycin C and triamcinoloneimpregnated biodegradable nasal packing(TABP)in endoscopic dacryocystorhinostomy(DCR).And to evaluate the efficacy of combining intraoperative mitomycin C and TABP for endoscopic DCR.●METHODS:A total of 198 eyes of 148 patients who underwent endoscopic DCR for acquired nasolacrimal duct obstruction were retrospectively analysed.The patients were randomly divided into three groups:Group A included patients treated without intraoperative mitomycin C but with TABP,Group B included patients treated without triamcinolone but with intraoperative mitomycin C and normal saline-impregnated nasal packing,and Group C included patients treated with intraoperative mitomycin C and TABP.●RESULTS:The results revealed no significant difference in the overall success rates between Groups A(86.8%)and B(89.2%;P=0.377).However,Group C(97.5%)showed a significantly higher overall success rate than Groups A and B.The incidence of granulomas was significantly lower in group C(5%)than in Groups A(20.8%)and B(15.2%;P=0.009).Other complications,such as crust,synechiae,and revision surgery,did not differ significantly among the three groups.●CONCLUSION:The combination of intraoperative mitomycin C and TABP effectively prevents granulomas and enhances surgical success rate.Additionally,there is no statistically significant difference observed between the use of mitomycin C or TABP alone.
文摘In this editorial we comment on the article published in the recent issue of the World Journal of Gastrointestinal Endoscopy 2023;15(11):634-680.Gastric cancer(GC)remains the fifth most common malignancy and the fourth leading cause of cancer-related death worldwide.The overall prevalence of GC has declined,although that of proximal GC has increased over time.Thus,a significant proportion of GC cases and deaths can be avoided if preventive interventions are taken.Early GC(EGC)is defined as GC confined to the mucosa or submucosa.Endoscopic resection is considered the most appropriate treatment for precancerous gastrointestinal lesions improving patient quality of life,with reduced rates of complications,shorter hospitalization period,and lower costs when compared to surgical resection.Endoscopic mucosal resection(EMR)and endoscopic sub-mucosal dissection(ESD)are representative endoscopic treatments for EGC and precancerous gastric lesions.Standard EMR implies injection of a saline solution into the sub-mucosal space,followed by excision of the lesion using a snare.Complete resection rates vary depending on the size and severity of the lesion.When using conventional EMR methods for lesions less than 1 cm in size,the complete resection rate is approximately 60%,whereas for lesions larger than 2 cm,the complete resection rate is low(20%-30%).ESD can be used to remove tumors exceeding 2 cm in diameter and lesions associated with ulcers or submucosal fibrosis.Compared with EMR,ESD has higher en bloc resection rates(90.2%vs 51.7%),higher complete resection rates(82.1 vs 42.2%),and lower recurrence rates(0.65%vs 6.05%).Thus,innovative techniques have been introduced.
