Several features of drug-induced mucosal alterations have been observed in the upper gastrointestinal tract,i.e.,the esophagus,stomach,and duodenum.These include pill-induced esophagitis,desquamative esophagitis,worsening of gastroesophageal reflux,chemotherapy-induced esophagitis,proton pump inhibitor-induced gastric mucosal changes,medication-induced gastric erosions and ulcers,pseudomelanosis of the stomach,olmesartan-related gastric mucosal inflammation,lanthanum deposition in the stomach,zinc acetate hydrate tabletinduced gastric ulcer,immune-related adverse event gastritis,olmesartan-associated sprue-like enteropathy,pseudomelanosis of the duodenum,and lanthanum deposition in the duodenum.For endoscopists,acquiring accurate knowledge regarding these diverse drug-induced mucosal alterations is crucial not only for the correct diagnosis of these lesions but also for differential diag-nosis of other conditions.This minireview aims to provide essential information on druginduced mucosal alterations observed on esophagogastroduodenoscopy,along with representative endoscopic images. 展开更多

BACKGROUND Gastroesophageal reflux disease(GERD)is a common disease worldwide with varying clinical presentations and risk factors.Prevalence data for Africa is lacking,but an increasing trend is expected due to demographic and epidemiological transitions.Although endoscopic studies for general gastrointestinal disorders have shown some patients with erosive esophagitis(EE),no studies in Ethiopia have investigated the clinical characteristics,risk factors,and severity of GERD using esophagogastroduodenoscopy(EGD).AIM To assess the clinical features of GERD in Ethiopian patients who underwent EGD and determine the severity and risk factors of EE.METHODS We conducted a multicenter,retrospective cross-sectional study of 221 patients diagnosed with GERD and endoscopic findings of EE at Trauma Associated Severe Hemorrhage and Amniotic Membrane Stem Cell between January 2019 and August 2022.Data were collected from electronic medical records and phone call interviews.We used descriptive statistics and binary logistic regression analysis with SPSS version 26 to identify the association between variables with a statistical significance set at P value<0.05.RESULTS The mean±SD age of the patients was 44.8(±15.9)years,with a male-to-female ratio of 1.6:1.The most commonly reported symptom was epigastric pain(80.5%),followed by heartburn(43%).Los Angeles(LA)-A EE was diagnosed in 71.1%of patients,followed by LA-B(14.9%),LA-C(7.7%),and LA-D(5.9%).Multivariate analysis showed that age 50 or above,presence of bleeding,and endoscopic findings of duodenitis/duodenopathy were significantly associated with severe EE(P<0.05).Stricture and Barrett’s esophagus were observed in 4.5%and 1.36%of patients with EE,respectively.CONCLUSION Most of the patients had milder EE with fewer complications.However,severe EE was more prevalent in older patients and those with duodenitis/duodenopathy. 展开更多

Upper gastrointestinal bleeding remains a significant cause of hospital admissions. Even though the incidence of peptic ulcer disease and gastritis is decreasing, the incidence rates in neoplasm, Dieulafoy’s lesions, angiodysplasia, and esophagitis are trending up, which necessities physicians to be aware of those pathologies and their specifics. Here, we represent a case of a 62-year-old male on dual antiplatelet therapy who was transferred to our hospital due to severe melena with suspicion of upper gastrointestinal bleeding. Due to hemodynamic instability, the patient was intubated and started on vasopressors. However, several repeated EGDs and CTs of the abdomen with GI bleeding protocol did not reveal the location of active bleeding to stop it. At the same time, clinically, the patient was hemodynamically unstable with continued melena. On the last EGD, a small area of concern resembling gastric varix was clipped for identification purposes, and the patient underwent a selective angiogram with further diagnosis of Dieulafoy’s lesion, which was successfully embolized. Our case demonstrates that Dieulafoy’s lesions can present as severe life-threatening hemorrhage, hard to diagnose with traditional methods such as EGD or CTs, in which case it is recommended to proceed with an angiogram sooner rather than later for further diagnosis and treatment if needed. 展开更多

The worldwide burden of tuberculosis(TB)has increased and it can involve virtually any organ of the body.Intestinal TB accounts for about 2%of the cases of TB worldwide.The ileocecal region is the most commonly affected site,and the foregut is rarely involved.The reported incidence is approximately 0.5%.Esophageal TB presents with dysphagia,weight loss,and hematemesis in rare cases.Gastroduodenal TB usually manifests with symptoms such as nausea,vomiting,weight loss,and sometimes with gastric outlet obstruction.Gastroscopy may reveal shallow ulcers in stomach and duodenal deformity when underlying TB is suspected,therefore histopathology plays pivotal role.On computed tomography,duodenal TB typically manifests as duodenal strictures predominantly,accompanied by extrinsic compression,and occasionally as intraluminal mass.But their diagnosis can easily be missed if proper biopsies are not taken and samples are not sent for GeneXpert testing,TB polymerase chain reaction investigation and histopathological analysis.Despite being in close proximity to the lungs,the esophagus and stomach are rare sites of TB.The reasons could be low gastric pH and acidity which does not let mycobacterium grow.But there are various case reports of TB involving the foregut.We have summarized the rare cases of foregut TB in different sections and highlighted the importance of esophagogastroduodenoscopy,histopathology and advanced techniques like endoscopic ultrasound in establishing the diagnosis. 展开更多

Acute non-variceal upper gastrointestinal bleeding(ANVUGIB)is a common medical emergency in clinical practice.While the incidence has significantly reduced,the mortality rates have not undergone a similar reduction in the last few decades,thus presenting a significant challenge.This editorial outlines the key causes and risk factors of ANVUGIB and explores the current standards and recent updates in risk assessment scoring systems for predicting mortality and endoscopic treatments for achieving hemostasis.Since ANUVGIB predominantly affects the elderly population,the impact of comorbidities may be responsible for the poor outcomes.A thorough drug history is important due to the increasing use of antiplatelet agents and anticoagulants in the elderly.Early risk stratification plays a crucial role in deciding the line of management and predicting mortality.Emerging scoring systems such as the ABC(age,blood tests,co-morbidities)score show promise in predicting mortality and guiding clinical decisions.While conventional endoscopic therapies remain cornerstone approaches,novel techniques like hemostatic powders and over-the-scope clips offer promising alternatives,particularly in cases refractory to traditional modalities.By integrating validated scoring systems and leveraging novel therapeutic modalities,clinicians can enhance patient care and mitigate the substantial morbidity and mortality associated with ANVUGIB. 展开更多

Esophageal tuberculosis(ET)is a relatively rare clinical condition,characterized by often atypical clinical features.The lack of specificity in diagnostic methods,such as esophagogastroduodenoscopy and various imaging techniques,frequently leads to misdiagnosis and inappropriate treatments.Compared to esophagogastroduodenoscopy,endoscopic ultrasonography(EUS)offers a more comprehensive examination of esophageal tuberculosis lesions,including the extent of wall layer involvement and the internal structure characteristics of the lesions.Furthermore,when necessary,endoscopic ultrasonography-guided fine-needle aspiration can be employed to acquire deeper pathological tissue,significantly aiding diagnosis.When combined with the patient’s clinical presentation,endoscopic findings,and pathological features,EUS plays a crucial role in the definitive diagnosis of ET and in the differential diagnosis process.This article meticulously reviews both national and international literature to summarize the relevant features of ET,with a focus on its appearance under EUS,and to highlight the clinical value of EUS in enhancing the diagnosis of ET and in distinguishing it from other conditions.The aim is to offer guidance for the accurate diagnosis of ET. 展开更多

AIM:To determine whether topical lidocaine benefits esophagogastroduoduenoscopy(EGD) by decreasing propofol dose necessary for sedation or procedurerelated complications.METHODS:The study was designed as a prospective,single centre,double blind,randomised clinical trial and was conducted in 2012 between January and May(NCT01489891).Consecutive patients undergoing EGD were randomly assigned to receive supplemental topical lidocaine(L;50 mg in an excipient solution which was applied as a spray to the oropharynx) or placebo(P;taste excipients solution without active substance,similarly delivered) prior to the standard propofol sedation procedure.The propofol was administered as a bolus intravenous(iv) dose,with patients in the L and P groups receiving initial doses based on the patient’s American Society of Anaesthesiologists(ASA) classification(ASAⅠ-Ⅱ:0.50-0.60 mg/kg;ASA Ⅲ-Ⅳ:0.25-0.35 mg/kg),followed by 10-20 mg iv dose every 30-60 s at the anaesthetist’s discretion.Vital signs,anthropometric measurements,amount of propofol administered,sedation level reached,examination time,and the subjective assessments of the endoscopist’s and anaesthetist’s satisfaction(based upon a four point Likert scale) were recorded.All statistical tests were performed by the Stata statistical software suite(Release 11,2009;StataCorp,LP,College Station,TX,United States).RESULTS:No significant differences were found between the groups treated with lidocaine or placebo in terms of total propofol dose(310.7 ± 139.2 mg/kg per minute vs 280.1 ± 87.7 mg/kg per minute,P = 0.15) or intraprocedural propofol dose(135.3 ± 151.7 mg/kg per minute vs 122.7 ± 96.5 mg/kg per minute,P = 0.58).Only when the L and P groups were analysed with the particular subgroups of female,【 65-year-old,and lower anaesthetic risk level(ASA Ⅰ-Ⅱ) was a statistically significant difference found(L:336.5 ± 141.2 mg/kg per minute vs P:284.6 ± 91.2 mg/kg per minute,P = 0.03) for greater total propofol requirements).The total incidence of complications was also similar between the two groups,with the L group showing a complication rate of 32.2%(95%CI:21.6-45.0) and the P group showing a complication rate of 26.7%(95%CI:17.0-39.0).In addition,the use of lidocaine had no effect on the anaesthetist’s or endoscopist’s satisfaction with the procedure.Thus,the endoscopist’s satisfaction Likert assessments were equally distributed among the L and P groups:unsatisfactory,[L:6.8%(95%CI:2.2-15.5) vs P:0%(95%CI:0-4.8);neutral,L:10.1%(95%CI:4.2-19.9) vs P:15%(95%CI:7.6-25.7)];satisfactory,[L:25.4%(95%CI:10-29.6) vs P:18.3%(95%CI:15.5-37.6);and very satisfactory,L:57.6%(95%CI:54-77.7) vs P:66.6%(95%CI:44.8-69.7)].Likewise,the anaesthetist’s satisfaction Likert assessments regarding the ease of maintaining a patient at an optimum sedation level without agitation or modification of the projected sedation protocol were not affected by the application of lidocaine,as evidenced by the lack of significant differences between the scores for the placebo group:unsatisfactory,L:5.8%(95%CI:1.3-13.2) vs P:0%(95%CI:0-4.8);neutral,L:16.9%(95%CI:8.9-28.4) vs P:16.7%(95%CI:8.8-27.7);satisfactory,L:15.2%(95%CI:7.7-26.1) vs P:20.3%(95%CI:11.3-31.6);and very satisfactory,L:62.7%(95%CI:49.9-74.3) vs P:63.3%(95%CI:50.6-74.7).CONCLUSION:Topical pharyngeal anaesthesia is safe in EGD but does not reduce the necessary dose of propofol or improve the anaesthetist’s or endoscopist’s satisfaction with the procedure. 展开更多

AIM:To investigate the impact of esophagogastroduodenoscopy with conscious sedation on the subsequent 24-h catheter-based pH monitoring.METHODS:Fifty patients with extra-esophageal symptoms of gastroesophageal reflux disease undergoing ambulatory dual-probe 24-h pH monitoring were enrolled from March 2010 to August 2011.All of the data were collected prospectively and analyzed retrospectively.Thirty-six patients(72%,group A) underwent pH monitoring shortly after esophagogastroduodenoscopy(EGD) with conscious sedation,and 14 patients(28%,group B) underwent pH monitoring without conscious sedation.The 24-h pH data from two time periods were analyzed:the first 4 h(Period Ⅰ) and the remaining time of the study(Period Ⅱ).RESULTS:The mean age of the patients was 49.6 ± 12.5 years;20 patients(40%) were men.The baseline data,including age,sex,body mass index,reflux esophagitis,the Reflux Symptom Index,and the Reflux Findings Score,were comparable between the two groups.The percentage of total time with a pH < 4 and the frequency of acid reflux during Period Ⅰ were not significantly different between the two groups,as measured using both pharyngeal(0.03% ± 0.10% vs 0.07% ± 0.16%,P = 0.32;and 0.07 ± 0.23 episodes/h vs 0.18 ± 0.47 episodes/h,P = 0.33,respectively) and esophageal probes(0.96% ± 1.89% vs 0.42% ± 0.81%,P = 0.59;and 0.74 ± 1.51 episodes/h vs 0.63 ± 0.97 episodes/h,P = 0.49,respectively).The percentage of total time with a pH < 4 and the frequency of acid reflux were also not significantly different between Periods I and Ⅱ in group A patients,as measured using both pharyngeal(0.03% ± 0.10% vs 0.23% ± 0.85%,P = 0.21;and 0.07 ± 0.23 episodes/h vs 0.29 ± 0.98 episodes/h,P = 0.22,respectively) and esophageal probes(0.96% ± 1.89% vs 1.11% ± 2.57%,P = 0.55;and 0.74 ± 1.51 episodes/h vs 0.81 ± 1.76 episodes/h,P = 0.55,respectively).CONCLUSION:EGD with conscious sedation does not interfere with the results of subsequent 24-h pH monitoring in patients with extra-esophageal symptoms of gastroesophageal reflux disease. 展开更多
