Performance characteristics of retrograde single-balloon endoscopy: A single center experience

AIM: To evaluate the technical success, diagnostic yield(DY) and therapeutic potential of retrograde single balloon enteroscopy(rS BE). METHODS: A retrospective review of 136 rS BE procedures performed at a tertiary academic referral center from January 2006 and September 2013 was completed. Patient characteristics including age, gender and inpatient status were collected. The indication for the procedure was categorized into one of three groups: Obscure gastrointestinal bleeding(GIB), evaluation for Crohn's disease and abnormal imaging. Procedural characteristics including insertion depth(ID), procedure time, concordance with pre-procedural imaging and complications were also recorded. Lastly, DY, defined as the percentage of cases producing either a definitive diagnosis or findings that could explain clinical symptoms and therapeutic yield(TY), defined as the percentage of cases in which a definitive intervention was performed, were determined. Mucosal tattooing and biopsy alone were not included in the TY. RESULTS: A total of 136 rS BE procedures were identified. Mean patient age was 57.5(± 16.2) years, 67(49.2%) were male, and 110(80.9%) procedures were performed on an outpatient basis. Indications for rS BE included GIB in 55(40.4%), evaluation of inflammatory bowel disease(IBD) in 29(21.3%), and imaging suggestive of pathology other than GIB or IBD in 43(31.6%). Nine(6.6%) rS BEs were performed for other indications. Mean ID was 68.3(± 39.3) cm proximal to the ileocecal valve and mean time to completion was 41.7(± 15.5) min. Overall, 73(53.7%) cases were diagnostic and 25(18.4%) cases were therapeutic in which interventions(argon plasma coagulation, stricture dilatation, polypectomy, etc.) were performed. Pre-procedural imaging was performed in 88(64.7%) patients. Endoscopic concordance of positive imaging findings was seen in 31(35.2%) cases. Follow up data was available in 93(68.4%) patients; 2(2.2%) reported post-procedural abdominal pain within 30 d following rS BE. There were no other reported complications. CONCLUSION: rS BE exhibits an acceptable diagnostic and TY, rendering it a safe and effective procedure for the evaluation and treatment of small bowel diseases.

Clinical usefulness of single-balloon endoscopy in patients with previously incomplete colonoscopy

AIM:To evaluate the clinical usefulness of singleballoon endoscopy(SBE) in patients in whom a colonoscope was technically difficult to insert previously.METHODS:The study group comprised 15 patients(8 men and 7 women) who underwent SBE for colonoscopy(30 sessions).The number of SBE sessions was 1 in 7 patients,2 in 5 patients,3 in 1 patient,4 in 1 patient,and 6 in 1 patient.In all patients,total colonoscopy was previously unsuccessful.The reasons for difficulty in scope passage were an elongated colon in 6 patients,severe intestinal adhesions after open surgery in 4,an elongated colon and severe intestinal adhesions in 2,a left inguinal hernia in 2,and multiple diverticulosis of the sigmoid colon in 1.Three endoscopists were responsible for SBE.The technique for inserting SBE in the colon was basically similar to that in the small intestine.The effectiveness of SBE was assessed on the basis of the success rate of total colonoscopy and the presence or absence of complications.We also evaluated the diagnostic and treatment outcomes of colonoscopic examinations with SBE.RESULTS:Total colonoscopy was successfully accomplished in all sessions.The mean insertion time to the cecum was 22.9 ± 8.9 min(range 9 to 40).Abnormalities were found during 21 sessions of SBE.The most common abnormality was colorectal polyps(20 sessions),followed by radiation colitis(3 sessions) and diverticular disease of the colon(3 sessions).Colorectal polyps were resected endoscopically in 15 sessions.A total of 42 polyps were resected endoscopically,using snare polypectomy in 32 lesions,hot biopsy in 7 lesions,and endoscopic mucosal resection in 3 lesions.Fifty-six colorectal polyps were newly diagnosed on colonoscopic examination with SBE.Histopathologically,these lesions included 2 intramucosal cancers,42 tubular adenomas,and 2 tubulovillous adenomas.The mean examination time was 48.2 ± 20.0 min(range 25 to 90).Colonoscopic examination or endoscopic treatment with SBE was not associated with any serious complications.CONCLUSION:SBE is a useful and safe procedure in patients in whom a colonoscope is technically difficult to insert.

Role of second look endoscopy in endoscopic submucosal dissection and peptic ulcer bleeding:Meta-analysis of randomized controlled trials

BACKGROUND Second-look endoscopy(SLE)to prevent recurrent bleeding in patients with peptic ulcer disease(PUD)and those undergoing endoscopic submucosal dissection(ESD)is routinely being performed.Conflicting evidence exists regarding efficacy,risk,benefit,and cost-effectiveness.AIM To identify the role and effectiveness of SLE in ESD and PUD,associated rebleeding and PUD-related outcomes like mortality,hospital length of stay,need for endoscopic or surgical intervention and blood transfusions.METHODS A systematic review of literature databases PubMed,Cochrane,and Embase was conducted from inception to January 5,2023.Randomized controlled trials that compared patients with SLE to those who did not have SLE or evaluated the role of prophylactic hemostasis during SLE compared to other conservative interventions were included.The study was conducted per PRISMA guidelines,and the protocol was registered in PROSPERO(ID CRD42023427555:).RevMan was used to perform meta-analysis,and Mantel-Haenszel Odds ratio(OR)were generated using random effect models.RESULTS A total of twelve studies with 2687 patients were included in our systematic review and meta-analysis,of which 1074 patients underwent SLE after ESD and 1613 patients underwent SLE after PUD-related bleeding.In ESD,the rates of rebleeding were 7%in the SLE group compared to 4.4%in the non-SLE group with OR 1.65,95%confidence intervals(CI)of 0.96 to 2.85;P=0.07,whereas it was 11%in the SLE group compared to 13%in the non-SLE group with OR 0.895%CI:0.50 to 1.29;P=0.36.The mean difference in the blood transfusion rates in the SLE and no SLE group in PUD was OR 0.01,95%CI:-0.22 to 0.25;P=0.91.In SLE vs non-SLE groups with PUD,the OR for Endoscopic intervention was 0.29,95%CI:0.08 to 1.00;P=0.05 while it was OR 2.03,95%CI:0.95 to 4.33;P=0.07,for surgical intervention.The mean difference in the hospital length of stay was-3.57 d between the SLE and no SLE groups in PUD with 95%CI:-7.84 to 0.69;P=0.10,denoting an average of approximately 3 fewer days of hospital stay among patients with PUD who underwent SLE.For mortality between SLE and non-SLE groups in PUD,the OR was 0.88,95%CI:0.45 to 1.72;P=0.70.CONCLUSION SLE does not confer any benefit in preventing ESD and PUD-associated rebleeding.SLE also does not provide any significant improvement in mortality,need for interventions,or blood transfusions in PUD patients.SLE decreases the hospital length of stay on average by 3.5 d in PUD patients.

Capsule endoscopy and panendoscopy:A journey to the future of gastrointestinal endoscopy

In 2000,the small bowel capsule revolutionized the management of patients with small bowel disorders.Currently,the technological development achieved by the new models of double-headed endoscopic capsules,as miniaturized devices to evaluate the small bowel and colon[pan-intestinal capsule endoscopy(PCE)],makes this non-invasive procedure a disruptive concept for the management of patients with digestive disorders.This technology is expected to identify which patients will require conventional invasive endoscopic procedures(colonoscopy or balloon-assisted enteroscopy),based on the lesions detected by the capsule,i.e.,those with an indication for biopsies or endoscopic treatment.The use of PCE in patients with inflammatory bowel diseases,namely Crohn’s disease,as well as in patients with iron deficiency anaemia and/or overt gastrointestinal(GI)bleeding,after a non-diagnostic upper endoscopy(esophagogastroduodenoscopy),enables an effective,safe and comfortable way to identify patients with relevant lesions,who should undergo subsequent invasive endoscopic procedures.The recent development of magnetically controlled capsule endoscopy to evaluate the upper GI tract,is a further step towards the possibility of an entirely non-invasive assessment of all the segments of the digestive tract,from mouth-to-anus,meeting the expectations of the early developers of capsule endoscopy.

Endoscopic features and treatments of gastric cystica profunda

BACKGROUND Gastric cystica profunda(GCP)represents a rare condition characterized by cystic dilation of gastric glands within the mucosal and/or submucosal layers.GCP is often linked to,or may progress into,early gastric cancer(EGC).AIM To provide a comprehensive evaluation of the endoscopic features of GCP while assessing the efficacy of endoscopic treatment,thereby offering guidance for diagnosis and treatment.METHODS This retrospective study involved 104 patients with GCP who underwent endoscopic resection.Alongside demographic and clinical data,regular patient followups were conducted to assess local recurrence.RESULTS Among the 104 patients diagnosed with GCP who underwent endoscopic resection,12.5%had a history of previous gastric procedures.The primary site predominantly affected was the cardia(38.5%,n=40).GCP commonly exhibited intraluminal growth(99%),regular presentation(74.0%),and ulcerative mucosa(61.5%).The leading endoscopic feature was the mucosal lesion type(59.6%,n=62).The average maximum diameter was 20.9±15.3 mm,with mucosal involvement in 60.6%(n=63).Procedures lasted 73.9±57.5 min,achieving complete resection in 91.3%(n=95).Recurrence(4.8%)was managed via either surgical intervention(n=1)or through endoscopic resection(n=4).Final pathology confirmed that 59.6%of GCP cases were associated with EGC.Univariate analysis indicated that elderly males were more susceptible to GCP associated with EGC.Conversely,multivariate analysis identified lesion morphology and endoscopic features as significant risk factors.Survival analysis demonstrated no statistically significant difference in recurrence between GCP with and without EGC(P=0.72).CONCLUSION The findings suggested that endoscopic resection might serve as an effective and minimally invasive treatment for GCP with or without EGC.

Imaging and endoscopic tools in pediatric inflammatory bowel disease: What’s new?

Pediatric inflammatory bowel disease(IBD)is a chronic inflammatory disorder,with increasing incidence and prevalence worldwide.There have been recent advances in imaging and endoscopic technology for disease diagnosis,treatment,and monitoring.Intestinal ultrasound,including transabdominal,transperineal,and endoscopic,has been emerging for the assessment of transmural bowel inflammation and disease complications(e.g.,fistula,abscess).Aside from surgery,IBD-related intestinal strictures now have endoscopic treatment options including through-the-scope balloon dilatation,injection,and needle knife stricturotomy and new evaluation tools such as endoscopic functional lumen imaging probe.Unsedated transnasal endoscopy may have a role in patients with upper gastrointestinal Crohn’s disease or those with IBD with new upper gastrointestinal symptoms.Improvements to dysplasia screening in pediatric patients with longstanding colonic disease or primary sclerosing cholangitis hold promise with the addition of virtual chromoendoscopy and ongoing research in the field of artificial intelligence-assisted endoscopic detection.Artificial intelligence and machine learning is a rapidly evolving field,with goals of further personalizing IBD diagnosis and treatment selection as well as prognostication.This review summarized these advancements,focusing on pediatric patients with IBD.

Endoscopic detection and diagnostic strategies for minute gastric cancer:A real-world observational study

BACKGROUND Minute gastric cancers(MGCs)have a favorable prognosis,but they are too small to be detected by endoscopy,with a maximum diameter≤5 mm.AIM To explore endoscopic detection and diagnostic strategies for MGCs.METHODS This was a real-world observational study.The endoscopic and clinicopathological parameters of 191 MGCs between January 2015 and December 2022 were retrospectively analyzed.Endoscopic discoverable opportunity and typical neoplastic features were emphatically reviewed.RESULTS All MGCs in our study were of a single pathological type,97.38%(186/191)of which were differentiated-type tumors.White light endoscopy(WLE)detected 84.29%(161/191)of MGCs,and the most common morphology of MGCs found by WLE was protruding.Narrow-band imaging(NBI)secondary observation detected 14.14%(27/191)of MGCs,and the most common morphology of MGCs found by NBI was flat.Another three MGCs were detected by indigo carmine third observation.If a well-demarcated border lesion exhibited a typical neoplastic color,such as yellowish-red or whitish under WLE and brownish under NBI,MGCs should be diagnosed.The proportion with high diagnostic confidence by magnifying endoscopy with NBI(ME-NBI)was significantly higher than the proportion with low diagnostic confidence and the only visible groups(94.19%>56.92%>32.50%,P<0.001).CONCLUSION WLE combined with NBI and indigo carmine are helpful for detection of MGCs.A clear demarcation line combined with a typical neoplastic color using nonmagnifying observation is sufficient for diagnosis of MGCs.MENBI improves the endoscopic diagnostic confidence of MGCs.

Oesophageal Mycosis: Epidemiological and Clinical Aspects and Risk Factors for Occurrence in the Digestive Endoscopy Unit of the Donka National Hospital, Conakry CHU

Introduction: Oesophageal mycosis (OM) is one of the most common opportunistic infections in patients infected with HIV (Human Immunodeficiency Virus). However, this condition is increasingly observed in immunocompetent subjects. The aim of this study was to determine the endoscopic prevalence, clinical characteristics and risk factors for the occurrence of oesophageal mycosis in our department. Patients and Method: This was a prospective cross-sectional study of all patients who underwent oeso-gastroduodenal fibroscopy during the period from 1st January to 31st December 2022, i.e. one year, at the digestive endoscopy unit of the hepato-gastroenterology department of the Donka CHU national hospital in Conakry. All patients found to have oesophageal mycosis by FOGD were included. The endoscopy was performed using appropriate equipment: A Fujinon 4400 video endoscopy column;Three Fujinon EG 590 video gastroscopes;A hoover;Data were collected using a pre-established survey form and analysed using Epi info software version 6.0.4;Pearson’s Chi2 test as a test of independence and the exact 5% threshold ficher test. Results: Out of 1343 upper gastrointestinal endoscopies performed, 107 cases of oesophageal mycosis were found, representing a prevalence of 7.96%. The mean age was 40 years, with a male predominance of 55.42%. The sex ratio M/F was 1.24. The 45 and over age group was the most affected, with a prevalence of 40.43%, followed by the [35 - 45] age group, with a prevalence of 22.43%. Clinical symptoms were dominated by epigastralgia in 74.76% of cases, followed by odynophagia in 37.38% of cases, nausea and vomiting in 28.03% of cases, and pyrosis in 26.16% of cases. Oesophageal mycosis without oesophagitis was the most common endoscopic finding in 70% of cases. The main associated endoscopic lesions were erythemato-erosive and congestive gastropathy in 28.03% of cases, peptic oesophagitis (9.34%) and gastric ulcer (5.60%). The main risk factors found were positive HIV serology in 39.25% of cases, and diabetes in 24.30% of cases, with a statistically significant relationship of 0.02 and 0.01 respectively. Conclusion: Oesophageal mycosis is the most common opportunistic infection in patients with impaired cellular immunity. The prevalence of oesophageal mycosis in our series was 7.96%. This study enabled us to identify the main risk factors for the occurrence of oesophageal mycosis. Our country needs to step up its programme to combat and prevent immunodeficiency diseases, particularly HIV and diabetes.

Standard-definition White-light,High-definition White-light versus Narrow-band Imaging Endoscopy for Detecting Colorectal Adenomas:A Multicenter Randomized Controlled Trial

Objective This study aimed to compare the performance of standard-definition white-light endoscopy(SD-WL),high-definition white-light endoscopy(HD-WL),and high-definition narrow-band imaging(HD-NBI)in detecting colorectal lesions in the Chinese population.Methods This was a multicenter,single-blind,randomized,controlled trial with a non-inferiority design.Patients undergoing endoscopy for physical examination,screening,and surveillance were enrolled from July 2017 to December 2020.The primary outcome measure was the adenoma detection rate(ADR),defined as the proportion of patients with at least one adenoma detected.The associated factors for detecting adenomas were assessed using univariate and multivariate logistic regression.Results Out of 653 eligible patients enrolled,data from 596 patients were analyzed.The ADRs were 34.5%in the SD-WL group,33.5%in the HD-WL group,and 37.5%in the HD-NBI group(P=0.72).The advanced neoplasm detection rates(ANDRs)in the three arms were 17.1%,15.5%,and 10.4%(P=0.17).No significant differences were found between the SD group and HD group regarding ADR or ANDR(ADR:34.5%vs.35.6%,P=0.79;ANDR:17.1%vs.13.0%,P=0.16,respectively).Similar results were observed between the HD-WL group and HD-NBI group(ADR:33.5%vs.37.7%,P=0.45;ANDR:15.5%vs.10.4%,P=0.18,respectively).In the univariate and multivariate logistic regression analyses,neither HD-WL nor HD-NBI led to a significant difference in overall adenoma detection compared to SD-WL(HD-WL:OR 0.91,P=0.69;HD-NBI:OR 1.15,P=0.80).Conclusion HD-NBI and HD-WL are comparable to SD-WL for overall adenoma detection among Chinese outpatients.It can be concluded that HD-NBI or HD-WL is not superior to SD-WL,but more effective instruction may be needed to guide the selection of different endoscopic methods in the future.Our study’s conclusions may aid in the efficient allocation and utilization of limited colonoscopy resources,especially advanced imaging technologies.

Clinical and demographic features of patients undergoing videocapsule endoscopy management:A descriptive study

BACKGROUND Video-capsule endoscopy(VCE)is an efficient tool that has proven to be highly useful in approaching several gastrointestinal diseases.VCE was implemented in Colombia in 2003,however current characterization of patients undergoing VCE in Colombia is limited,and mainly comes from two investigations conducted before the SARS-CoV-2 pandemic period.AIM To describe the characteristics of patients undergoing VCEs and establish the main indications,findings,technical limitations,and other outstanding features.METHODS A descriptive study was carried out using data from reports of VCE(PillCam SB3 system)use in a Gastroenterology Unit in Bogotá,Colombia between September 2019 and January 2023.Demographic and clinical variables such as indication for the VCE,gastric and small bowel transit times(GTT,SBTT),endoscopic preparation quality,and limitations were described[n(%),median(IQR)].RESULTS A total of 133 VCE reports were analyzed.Most were in men with a median age of 70 years.The majority had good preparation(96.2%),and there were technical limitations in 15.8%of cases.The main indications were unexplained anemia(91%)or occult bleeding(23.3%).The median GTT and SBTT were 14 and 30 minutes,respectively.The frequencies of bleeding stigma(3.79%)and active bleeding(9.09%)were low,and the most frequent abnormal findings were red spots(28.3%),erosions(17.6%),and vascular ectasias(12.5%).CONCLUSION VCE showed high-level safety.The main indication was unexplained anemia.Active bleeding was the most frequent finding.Combined with artificial intelligence,VCE can improve diagnostic precision and targeted therapeutic interventions.

T1 colorectal cancer management in the era of minimally invasive endoscopic resection

T1 colorectal cancer(CRC),defined by tumor invasion confined to the submucosa,has historically been managed by surgery.Improved understanding of recurrence and lymph node metastases risk,coupled with advances in endoscopic resection techniques,have led to an increasing capacity for organ-sparing local excision.Minimally invasive management of T1 CRC begins with optical evaluation of the lesion to diagnose invasive disease and quantify depth of invasion,which informs therapeutic decision making.Modality selection between various available endoscopic resection techniques depends upon lesion characteristics,technique risk-benefit profiles,and location-specific implications.Following endoscopic resection,established histopathology features determine the risk of recurrence and subsequent management including surveillance or adjuvant surgical excision.The management of non-operative candidates deviates from conventional recommendations with emerging treatment strategies in select populations.

Double-nylon purse-string suture technique: Another addition to the endoscopist's toolbox for full-thickness defect closure

Iatrogenic perforation is the most feared adverse event in endoscopy.With the expansion of interventional endoscopy in favor of traditional surgery,it is now more crucial than ever to develop effective defect closure techniques.This has culminated in the dissemination of multiple novel closure technologies,including through-the-scope clips,over-the-scope clips,through-the-scope suturing and over-the-scope suturing devices.In this editorial,we comment on the recent publication by Wang and colleagues discussing the performance of the double-nylon purse-string suture technique in the closure of large(>3 cm)gastric full-thickness defects.This technique offers a promising,practical and cost-effective approach to closure of large full-thickness defects that can be readily imple-mented across diverse healthcare settings.

Yield of alarm features in predicting significant endoscopic findings among hospitalized patients with dyspepsia

BACKGROUND Dyspepsia is a very prevalent upper gastrointestinal tract symptoms complex.Some of these symptoms might arise from serious underlying diseases,so the promotion of evidence-based guidelines could potentially better align evaluation and treatment.AIM To determine the value of alarm features as a predictive factor for significant endoscopic findings(SEFs)among hospitalized patients presenting with dyspepsia.METHODS We conducted a retrospective case-control study including information about 6208 endoscopic procedures performed for hospitalized patients.Patients were divided into two groups,with and without SEFs,and compared to elucidate the ability of the different alarm features to predict SEFs.RESULTS During the study,605 patients fulfilled the inclusion criteria.When the demographics and clinical characteristics of the two groups were compared,tachycardia(P<0.05),normocytic anemia,(P<0.05),leukocytosis(P<0.05),and hypoalbuminemia(P<0.05)documented on admission prior to endoscopy were strong predictors of SEFs.Among the alarm features,upper gastrointestinal bleeding,persistent vomiting,odynophagia[odds ratio(OR)=3.81,P<0.05;OR=1.75,P=0.03;and OR=7.81,P=0.07,respectively]were associated with SEFs.Unexplained weight loss was strongly associated with malignancy as an endoscopic finding(OR=2.05;P<0.05).In addition,long-term use of anti-aggregate medications other than aspirin(P<0.05)was correlated to SEFs.CONCLUSION Novel predictors of SEFs were elucidated in this study.These parameters could be used as an adjunctive in decision making regarding performing upper endoscopy in hospitalized patients with dyspepsia.

Recanalization of anastomotic occlusion following rectal cancer surgery using a rendezvous endoscopic technique with transillumination:A case report

BACKGROUND Colorectal anastomotic occlusion is a serious complication of colorectal cancer surgery.Although several treatment strategies have been proposed,the mana-gement of anastomotic occlusion remains challenging.In this report,we present a case of anastomotic occlusion recanalization performed using a novel technique involving two endoscopes,one for radial incision and the other serving as a guide light.This novel technique offers significant advantages in terms of operational feasibility,reduced invasiveness,rapid recovery,and shortened hospital stay.CASE SUMMARY A 37-year-old man underwent low anterior resection and prophylactic double-lumen ileostomy for rectal cancer in June,2023.Two months later,complete anastomotic occlusion was observed on colonoscopy.Therefore,we developed a novel atresia recanalization technique.Two endoscopes were placed,one through the colonic anastomosis and the other through the anus.A radial incision was successfully made from the colonic side,guided by the light of the endoscope from the anal side.Atresia recanal-ization was performed within 20 minutes.Three weeks after recanalization,colonoscopy revealed that the diameter of the colorectal anastomosis was approximately 16 mm and the patient therefore underwent stoma reversal in September.During the follow-up period of approximately one year,the patient remained well and no stenosis or obstruction symptoms were observed.CONCLUSION Endoscopic atresia recanalization of colorectal anastomotic occlusion assisted by an opposing light source is safe and effective.

Effect of navigation endoscopy combined with threedimensional printing technology in the treatment of orbital blowout fractures

●AIM:To explore the combined application of surgical navigation nasal endoscopy(NNE)and three-dimensional printing technology(3DPT)for the adjunctive treatment of orbital blowout fractures(OBF).●METHODS:Retrospective analysis was conducted on the data of patients with OBF who underwent surgical treatment at the Affiliated Eye Hospital of Nanchang University between July 2012 and November 2022.The control group consisted of patients who received traditional surgical treatment(n=43),while the new surgical group(n=52)consisted of patients who received NNE with 3DPT.The difference in therapeutic effects between the two groups was evaluated by comparing the duration of the operation,best corrected visual acuity(BCVA),enophthalmos difference,recovery rate of eye movement disorder,recovery rate of diplopia,and incidence of postoperative complications.●RESULTS:The study included 95 cases(95 eyes),with 63 men and 32 women.The patients’age ranged from 5 to 67y(35.21±15.75y).The new surgical group and the control group exhibited no statistically significant differences in the duration of the operation,BCVA and enophthalmos difference.The recovery rates of diplopia in the new surgical group were significantly higher than those in the control group at 1mo[OR=0.03,95%CI(0.01–0.15),P<0.0000]and 3mo[OR=0.11,95%CI(0.03–0.36),P<0.0000]postoperation.Additionally,the recovery rates of eye movement disorders at 1 and 3mo after surgery were OR=0.08,95%CI(0.03–0.24),P<0.0000;and OR=0.01,95%CI(0.00–0.18),P<0.0000.The incidence of postoperative complications was lower in the new surgical group compared to the control group[OR=4.86,95%CI(0.95–24.78),P<0.05].●CONCLUSION:The combination of NNE and 3DPT can shorten the recovery time of diplopia and eye movement disorder in patients with OBF.

Global research landscape of Peutz-Jeghers syndrome and successful endoscopic management of intestinal intussusception in patients with recurrent laparotomies

BACKGROUND Peutz-Jeghers syndrome(PJS)has brought significant physical,psychological and economic burdens on the patients and their families due to its early onset,diagnostic and therapeutic challenges and increased recurrence risk.AIM To explore the current research status and emerging hotspots of PJS.METHODS Studies on PJS published during 1994-2023 were gathered based on Web of Science Core Collection.Additionally,a case of PJS-induced intestinal intussusception,successfully treated with endoscopic methods despite three laparotomies,was highlighted.Comprehensive bibliometric and visual analysis were conducted with VOSviewer,R and CiteSpace.RESULTS Altogether 1760 studies were identified,indicating a steady increase in the publication number.The United States had the highest influence,whereas the University of Helsinki emerged as the leading institution,and Aaltonen LA from the University of Helsinki was the most prolific author.Cancer Research,Oncogene and Endoscopy were the top three journals based on H-index.Keyword burst direction analysis revealed that"cancer risk","management","surveillance"and"familial pancreatic cancer"were the potential hotspots for investigation.Additionally,"early detection","capsule endoscopy","clinical management","double-balloon endoscopy","familial pancreatic cancer"and"molecular genetic basis"were identified as the key clusters of co-cited references.Endoscopic polypectomy remained effective on resolving intestinal intussusception in patients who underwent three previous laparotomies.CONCLUSION In the last three decades,global publications related to PJS show a steadily increasing trend in number.Endoscopic management is currently a research hotspot.

Gastric cystica profunda:Another indication for minimally invasive endoscopic resection techniques?

Gastric cancer presents a significant global health burden,as it is the fifth most common malignancy and fourth leading cause of cancer mortality worldwide.Variations in incidence rates across regions underscores the multifactorial etiology of this disease.The overall 5-year survival rate remains low despite advances in its diagnosis and treatment.Although surgical gastrectomy was previously standard-of-care,endoscopic resection techniques,including endoscopic mucosal resection and endoscopic submucosal dissection(ESD)have emerged as effective alternatives for early lesions.Compared to surgical resection,endoscopic resection techniques have comparable 5-year survival rates,reduced treatment-related adverse events,shorter hospital stays and lower costs.ESD also enables en bloc resection,thus affording organ-sparing curative endoscopic resection for early cancers.In this editorial,we comment on the recent publication by Geng et al regarding gastric cystica profunda(GCP).GCP is a rare gastric pseudotumour with the potential for malignant progression.GCP presents a diagnostic challenge due to its nonspecific clinical manifestations and varied endoscopic appearance.There are several gaps in the literature regarding the diagnosis and management of GCP which warrants further research to standardize patient management.Advances in endoscopic resection techniques offer promising avenues for GCP and early gastric cancers.

Endoscopic and pathological features of neoplastic transformation of gastric hyperplastic polyps:Retrospective study of 4010 cases

BACKGROUND Hyperplastic polyps,which represent 30%-93%of all gastric epithelial polyps,are the second most common type of gastric polyps after fundic gland polyps.They were previously considered to have no risk of neoplastic transformation.Recently,an increasing number of cases of gastric hyperplastic polyps(GHPs)combined with neoplastic changes have been reported;however,the specific mechanism underlying their transformation has not been thoroughly explored.AIM To investigate the clinical,endoscopic,and pathological characteristics of the neoplastic transformation of GHPs and explore the risk factors.METHODS A retrospective analysis was performed on 4010 cases of GHPs diagnosed by gastroscopy and pathological examination at the hospital from 2005 to 2021.In total,3874,119,and 17 cases were in the group without intraepithelial neoplasia(IN),with low-grade IN,and with high-grade IN,respectively.The data analysis examined the association of endoscopic and pathological features with risk factors for neoplastic transformation.Factors with significant differences were entered into univariate logistic regression,followed by multivariate logistic regression analysis.RESULTS Univariate analysis revealed diameter,multiple polyp presence,redness,rough surface,lobulation,erosion,Yamada classification,location,and gastric mucosa were risk factors for neoplastic transformation.Multivariate analysis showed that age>65 years[odds ratio(OR)=1.789;95%confidence interval(CI):1.227-2.609;P=0.003],male sex(OR=1.680;95%CI:1.158-2.438;P=0.006),multiple polyps(OR=1.851;95%CI:1.230-2.784;P=0.003),pedunculated or semi-pedunculated shape(OR=2.722;95%CI:1.689-4.388;P<0.001),and polyp diameter were significantly associated with GHPs that demonstrated neoplastic transformation.Compared with chronic superficial gastritis,autoimmune gastritis,atrophic gastritis,and gastritis with IN were independent risk factors for neoplastic transformation[(OR=2.672;95%CI:1.559-4.579;P<0.001),(OR=1.876;95%CI:1.134-3.103;P=0.014),and(OR=5.299;95%CI:3.173–8.849;P<0.001),respectively].CONCLUSION Male sex,age>65 years,multiple polyps,pedunculated or semi-pedunculated shape,polyp size>1 cm,and specific background gastric mucosa are key indicators for predicting neoplastic transformation of GHPs.

Remimazolam for sedation in gastrointestinal endoscopy:A comprehensive review

Worldwide,a majority of routine endoscopic procedures are performed under some form of sedation to maximize patient comfort.Propofol,benzodiazepines and opioids continue to be widely used.However,in recent years,Remimazolam is gaining immense popularity for procedural sedation in gastrointestinal(GI)endoscopy.It is an ultra-short-acting benzodiazepine sedative which was approved by the Food and Drug Administration in July 2020 for use in procedural sedation.Remimazolam has shown a favorable pharmacokinetic and pharmacodynamic profile in terms of its non-specific metabolism by tissue esterase,volume of distribution,total body clearance,and negligible drug-drug interactions.It also has satisfactory efficacy and has achieved high rates of successful sedation in GI endoscopy.Furthermore,studies have demonstrated that the efficacy of Remimazolam is non-inferior to Propofol,which is currently a gold standard for procedural sedation in most parts of the world.However,the use of Propofol is associated with hemodynamic instability and respiratory depression.In contrast,Remimazolam has lower incidence of these adverse effects intra-procedurally and hence,may provide a safer alternative to Propofol in procedural sedation.In this comprehensive narrative review,highlight the pharmacologic characteristics,efficacy,and safety of Remimazolam for procedural sedation.We also discuss the potential of Remimazolam as a suitable alternative and how it can shape the future of procedural sedation in gastroenterology.

Endoscopic diagnosis and management of gallbladder carcinoma in minimally invasive era:New needs,new models

Gallbladder cancer(GBC)is a rare and lethal malignancy;however,it represents the most common type of biliary tract cancer.Patients with GBC are often diagnosed at an advanced stage,thus,unfortunately,losing the opportunity for curative surgical intervention.This situation leads to lower quality of life and higher mortality rates.In recent years,the rapid development of endoscopic equipment and techniques has provided new avenues and possibilities for the early and minimally invasive diagnosis and treatment of GBC.This editorial comments on the article by Pavlidis et al.Building upon their work,we explore the new needs and corresponding models for managing GBC from the endoscopic diagnosis and treatment perspective.
