Self-expanding metal stent for relieving the stricture after endoscopic injection for esophageal varices.

Esophageal stricture is one of the complications after esophageal varices sclerotherapy injection (ESI), and the incidence rate is between 2%-10%. To explore the efficacy of self-expanding metal stent (SEMS) for the stricture after endoscopic injection with cyanoacrylate (CYA) and sclerotherapy for esophageal varices. We retrospectively analyzed the efficacy of SEMS to improve the stricture after endoscopic injection with CYA and sclerotherapy for esophageal varices in 4 patients from February 2023 to June 2023. The strictures were improved in four patients after stenting. The stent was removed after two weeks because of chest pain with embedding into esophageal mucosa in one patient. The stent was removed after one month, however, the stent was reinserted because of the strictures happening again in two patients. The stent was removed after three months, however, the stent was reinserted because of the strictures happening again in one patient. The stent embedded into esophageal mucosa in three patients. There were 3 patients suffered reflux esophagitis, and the acid reflux was relieved by taking hydrotalcite. There was no other complication of esophageal perforation, bleeding from varices or infection. SEMS may relieve the stricture which happened after endoscopic injection with CYA and sclerotherapy for esophageal varices. However, when we should remove the stent still needs to be explored.

Study on the Application of Integrated Medical and Nursing Care Model in the Postoperative Period of Patients with Sclerotherapy for Esophageal Varicose Veins

Objective: To explore the application effect of medical and nursing integration management mode in the postoperative period of patients treated with sclerotherapy for esophageal varices. Methods: Randomly divided 64 cases of esophageal varices patients admitted to our hospital from October 2022 to October 2023 who underwent surgical treatment into two groups, and gave 32 cases of patients in the control group postoperative implementation of basic nursing care, and 32 cases of patients in the research group postoperative implementation of healthcare integration management mode, and compared the effect of the nursing care of the two groups of patients. Results: There are differences in nursing satisfaction, incidence of postoperative rebleeding, complication rate, and patients’ knowledge of disease-related common grip scores between the two groups of patients with esophageal varices after nursing care (P < 0.05), which is statistically significant. Conclusion: The implementation of integrated medical and nursing management mode for postoperative patients with sclerotherapy for esophageal varices has a significant effect on the prognosis of patients, reduces the occurrence of complications, and shortens the length of hospital stay.

EUS-Guided Vascular Interventions: Recent Advances.

Endoscopic ultrasound (EUS)-guided vascular interventions were first reported in 2000 in a study that evaluated the utility of EUS in sclerotherapy of esophageal varices. Currently, gastric variceal therapy and portosystemic pressure gradient (PPG) measurements are the most widely utilized applications. Ectopic variceal obliteration, splenic artery embolization, aneurysm/pseudoaneurysm treatment, portal venous sampling, and portosystemic shunt creation using EUS are some of the other emerging interventions. Since the release of the American Gastroenterological Association (AGA)'s commentary in 2023, which primarily endorses EUS-guided gastric variceal therapy and EUS-PPG measurement, several new studies have been published supporting the use of EUS for various vascular conditions. In this review, we present the recent advances in this field, critically appraising new studies and trials.

Endoscopic submucosal dissection for early esophageal squamous cell carcinoma after ligation and sclerotherapy of esophageal and gastric varices

Esophageal cancer ranked ten of the most common cancers in China. With the advancement of high-quality endoscopy and chromoendoscopic technique, early esophageal cancer can be diagnosed more easily, even combined with esophageal-gastric fundal varices. Endoscopic resection of early esophageal cancer is a minimally invasive treatment method for early esophageal cancer, and endoscopic submucosal dissection (ESD) is one of the standard treatments for early esophageal cancer in view of the risk of bleeding, the patient in this study successfully received ESD treatment after using endoscopic variceal ligation and endoscopic injection of tissue glue and sclerosing agent before ESD surgery. ESD treatment is safe and feasible for early esophageal cancer patients with cirrhosis of esophageal-gastric fundal varices.

Current Pediatric Endoscopy Training Situation in the Asia-Pacific Region: A Collaborative Survey by the Asian Pan-Pacific Society for Pediatric Gastroenterology, Hepatology and Nutrition Endoscopy Scientific Subcommittee.

To date, there is no region-specific guideline for pediatric endoscopy training. This study aimed to illustrate the current status of pediatric endoscopy training in Asia-Pacific region and identify opportunities for improvement. A cross-sectional survey, using a standardized electronic questionnaire, was conducted among medical schools in the Asia-Pacific region in January 2024. A total of 57 medical centers in 12 countries offering formal Pediatric Gastroenterology training programs participated in this regional survey. More than 75% of the centers had an average case load of <10 cases per week for both diagnostic and therapeutic endoscopies. Only 36% of the study programs employed competency-based outcomes for program development, whereas nearly half (48%) used volume-based curricula. Foreign body retrieval, polypectomy, percutaneous endoscopic gastrostomy, and esophageal variceal hemostasis, that is, sclerotherapy or band ligation (endoscopic variceal sclerotherapy and endoscopic variceal ligation), comprised the top four priorities that the trainees should acquire in the autonomous stage (unconscious) of competence. Regarding the learning environment, only 31.5% provided formal hands-on workshops/simulation training. The direct observation of procedural skills was the most commonly used assessment method. The application of a quality assurance (QA) system in both educational and patient care (Pediatric Endoscopy Quality Improvement Network) aspects was present in only 28% and 17% of the centers, respectively. Compared with Western academic societies, the limited availability of cases remains a major concern. To close this gap, simulation and adult endoscopy training are essential. The implementation of reliable and valid assessment tools and QA systems can lead to significant development in future programs.

Esophageal variceal ligation plus sclerotherapy vs. ligation alone for the treatment of esophageal varices.

BackgroundThis study aimed to evaluate the efficacy and adverse events of esophageal variceal ligation (EVL) vs. EVL combined with endoscopic injection sclerosis (EIS) in the therapy of esophageal varices.MethodsPatients from January 2017 to August 2021 who received EVL alone (control group) or EVL plus EIS (intervention group) were enrolled in this retrospective study. Efficacy, including rebleeding (clinically hematemesis or melena, confirmed by endoscopy as esophagogastric varices bleeding), variceal recurrence rate (the presence of esophagogastric varices which is needed to be treated again) the number of sessions performed to complete eradication of varices, and safety (adverse events) were compared. The variceal recurrence-associated factors were derived by univariate and multivariate logistic regression analyses.ResultsThe variceal recurrence and rebleeding rate in the intervention group showed significantly lower than the control group (2.6% vs 10.3%, P = 0.006 and 20.7% vs 37.5%, P = 0.029, P = 0.006, respectively, in the 12-month follow-up). The adverse events (fever, chest pain, swallowing, and esophageal stricture) showed no significant difference between the two groups (P > 0.05). Further research showed that the efficacy of the intervention group was better than the control group only achieved in prophylactically endoscopic treatment patients. The diameter of esophageal varices and gastric varices co-exist showed significant effects on variceal recurrence in intervention group [odds ratio (OR) = 15.856; 95% confidence interval (CI), 1.709–160.143; P = 0.016 and OR = 4.5; 95% CI, 1.42–20.028; P = 0.021; respectively].ConclusionsThe intervention group may obtain lower recurrence, rebleeding rate, and fewer sessions performed to complete eradication of varices (number of sessions) and similar incidence of adverse events, especially for prophylactically treatment. Among the intervention group, the diameter of esophageal varices and gastric varices were closely associated with variceal recurrence.

Sclerotherapy of oesophageal varices may induce chronic constrictive pericarditis in children.

Constrictive pericarditis is rare in children and can be difficult to diagnose. It has been described in adults after sclerotherapy of oesophageal varices but not in children. We report two cases of chronic constrictive pericarditis after sclerotherapy of oesophageal varices in children with portal cavernoma. Constrictive pericarditis should be considered as a cause of refractory ascites.

Temporary hypotension and ventilation difficulty during endoscopic injection sclerotherapy for esophageal varices in a child with Fontan circulation: a case report

BackgroundEndoscopic procedures are rarely performed in children with congenital heart disease (CHD); therefore, the associated complications are unknown. We report an abrupt change in circulatory and respiratory condition during endoscopic injection sclerotherapy for esophageal varices.Case presentationA 9-year-old boy with a history of total anomalous pulmonary venous connection (TAPVC) repair and Fontan procedure for asplenia and a single ventricle with TAPVC underwent endoscopic injection sclerotherapy under general anesthesia for esophageal varices. Systolic blood pressure decreased from 70 to 50 mmHg following a sclerosant injection; a second injection reduced his peripheral oxygen saturation from 93 to 79% secondary to ventilation difficulty. Although we suspected anaphylaxis intraoperatively, postoperative imaging suggested that balloon dilation performed to prevent sclerosing agent leakage caused compression of the pulmonary venous chamber and trachea owing to the anomalous intrathoracic organ anatomy.ConclusionThorough understanding of the complex anatomy is important before performing endoscopic procedures in children with CHD to preoperatively anticipate possible intraoperative complications and select the optimal therapeutic approach and anesthesia management.

Prognostic and recurrence factors after endoscopic injection sclerotherapy for esophageal varices: Multivariate analysis with the propensity score matching: Multivariate analysis with propensity score matching.

Peri-esophageal collateral veins have been reported to be associated with the recurrence of esophageal varices (EVs). In this study, we retrospectively analyzed whether endoscopic ultrasonography (EUS) findings obtained just before endoscopic injection sclerotherapy (EIS) are associated with the success rate of intravariceal injection, recurrence rate of EVs, and overall survival rate (OS) of patients. Furthermore, we investigated the independent predictors associated with these factors by multivariate analysis. A total of 91 patients with risky EVs treated by EIS were analyzed. The primary endpoint was to identify independent predictors associated with the success rate of intravariceal injection, recurrence rate, and OS by multivariate analysis, to confirm the usefulness of EUS examination. The secondary endpoint was to clarify differences in recurrence rate and OS between patients who underwent additional argon plasma coagulation (APC) and those who did not, by the propensity score matching method. Luminal diameter of EVs and F factor were predictors of the success rate of intravariceal injection. APC was predictor of OS and recurrence of EVs. EUS findings were not associated with these factors. Propensity score matching (APC, 23; without APC, 23) showed that recurrence rate was significantly improved in the APC group (P = 0.050) and that OS had the tendency to be higher in the APC group (P = 0.068). Endoscopic ultrasonography findings before EIS were associated with successful intravariceal injection but were not associated with recurrence rate or OS. Additional APC could improve OS and reduce the recurrence of EVs.

Endoscopic Treatment as the Rescue Therapy for Recurrent Bleeding after Transjugular Intrahepatic Portosystemic Shunt (TIPS).

Background Transjugular intrahepatic portosystemic shunt (TIPS) is suggested as the salvage therapy for gastroesophageal variceal bleeding in cirrhosis. However, rebleeding might occur in some patients after TIPS. Currently, there is a lack of evidence in the endoscopic management of recurrent bleeding in these patients. Aims To evaluate the efficacy of endoscopic treatment in cirrhotic patients with recurrent bleeding after TIPS. Methods Cirrhotic patients with gastroesophageal varices who received endoscopic treatment for recurrent bleeding after TIPS were included. Results 6 patients were enrolled in this study. The median age of the patients was 47 years (range 27 to 65 years), and the duration of follow-up time was 346 (17-773) days. Stent stenosis or occlusion was found in 5 out of 6 patients after TIPS. Salvage endoscopic treatment, including esophageal variceal ligation (EVL), gastric variceal cyanoacrylate injection, esophageal variceal sclerotherapy, and balloon-occluded retrograde transvenous obliteration- (BRTO-) assisted endoscopic cyanoacrylate injection. Among included patients, 2 died shortly after EVL (14 and 19 days) due to variceal bleeding. Among other 4 patients, 2 had rebleeding episodes at 422 and 789 days, respectively. Conclusion Endoscopic treatment may be an option for recurrent bleeding after TIPS in selected patients. Further studies are needed to carefully define the indication and efficacy of this option.

Different Doses of Oxycodone for Endoscopic Injection Sclerotherapy of Esophageal Varices.

BackgroundThe aim of the present study was to evaluate the effects of different doses of oxycodone during endoscopic injection sclerotherapy (EIS) for esophageal varices with painless sclerosing agents.Material/MethodsA total of 119 patients were randomly divided into 3 groups: Group A, midazolam and 0.075 mg/kg oxycodone (n=40); Group B, midazolam and 0.1 mg/kg oxycodone (n=40); and Group C, midazolam and 0.125 mg/kg oxycodone (n=39). The main observation index was the incidence of body movement during the perioperative period. The secondary indices were additional propofol usage; postoperative analgesic usage; other adverse effects, such as hypoxia, myoclonus, and cough; and satisfaction scores for surgeons and patients.ResultsThe incidence rates for body movement during the perioperative period in groups A, B, and C were 33%, 13%, and 0, respectively (P<0.001). The satisfaction scores for surgeons and patients were highest in Group C (0.125 mg/kg oxycodone). The incidence rates for hypoxia before EIS were 15%, 8%, and 33% (P=0.026) and during EIS were 23%, 3%, and 0% (P<0.001), respectively. There were no significant between-group differences with respect to other adverse effects.ConclusionsThe ideal dose of oxycodone for perioperative analgesia during EIS for esophageal varices is 0.125 mg/kg.

Prognosis of bleeding recurrence after endoscopic sclerotherapy of esophageal varices

To improve prediction of recurrent bleeding after endoscopic sclerotherapy of esophageal varices. A prospective, observational, case-control study was performed. Immediate and long-term results of endoscopic sclerotherapy of esophageal varices were studied in 91 patients for the period from 2002 to 2016. Multiple regression analysis with binary response model was applied to analyze the prediction models. Recurrent bleeding occurred in 80.5 (20; 182) days after sclerotherapy (range 0-2557 days). Spearman's correlation analysis revealed a significant relationship between bleeding recurrence and erythrocyte count (R= -0.32), Child-Pugh class of liver cirrhosis (R=0.49), Child-Pugh score (5-15) (R=0.54), content of amino acids, HPro/Pro ratio (R=0.71). Prognostic indicators were selected by stepwise inclusion of predictors. Thus, the final version of regression equation is as follows: Y=exp (-0.17+0.93×Child-Pugh score-106.42×HPro/Pro)/[1+exp(-0.17+0.93×Child-Pugh score-106.42×HPro/Pro)]. High risk of recurrent bleeding from esophageal varices within 1 year after endoscopic sclerotherapy is determined by Y-value >0.5. An accuracy of this model is 89.6%, Se 94.3%, Sp 79.2%, PPV 90.9%, NPV 86.4%, OR 63.3, LR + 4.53, LR - 0.07. Thus, the proposed method is highly informative, effective, available and can be widely used in clinical practice.

Exacerbation of Portal Hypertensive Enteropathy after Endoscopic Injection Sclerotherapy for Esophageal Varices

Introduction: Portal hypertensive enteropathy (PHE) is a well-known small-bowel lesion that occurs with liver cirrhosis (LC) and is associated with increased hepatic venous pressure. However, it is unclear how esophageal varices (EV) treatment actually affects PHE. We aimed to analyze the effects of EV treatment on PHE. Methods: Among LC patients who underwent capsule endoscopy (CE) more than twice to confirm PHE at our hospital from February 2009 to September 2018, we targeted those with no change in the Child-Pugh classification after EV treatment for the prevention of bleeding. Patients were assigned to groups based on the EV treatment method (endoscopic injection sclerotherapy [EIS] group or endoscopic variceal ligation [EVL] group). We analyzed the PHE findings before and after treatment, and we investigated changes in the collateral vein using computed tomography imaging. Results: We analyzed 42 LC patients (27 men; mean age, 65.3 years); 20 were in the EIS group and 22 were in the EVL group. Exacerbation of PHE was significantly prevalent in the EIS group (90%) compared to that in the EVL group (50%). CE of PHE showed significantly prevalent exacerbation of villous edema in the EIS group (65%) compared to that in the EVL group (23%). Stenosis or disappearance of the feeding vessel (55%) and exacerbation of the hepatofugal collateral vein (35%) were significantly prevalent in the EIS group. Conclusions: EIS exacerbates PHE, especially villous edema, in LC patients with changes in collateral circulation.

Schistosomal portal hypertension: Randomized trial comparing endoscopic therapy alone or preceded by esophagogastric devascularization and splenectomy

Background. Upper gastrointestinal bleeding is a major cause of morbidity and mortality in patients with portal hypertension secondary to schistosomiasis mansoni.Aim. To evaluate the efficacy of combined surgery and sclerotherapy versus endoscopic treatment alone in the prophylaxis of esophageal variceal rebleeding due to portal hypertension in schistosomiasis.Material and methods. During a two-years period consecutive patients with schistosomiasis and a recent bleeding history were evaluated for prospective randomization. Absolute exclusion criteria were alcoholism or other liver diseases, whereas platelet count < 50,000/mm3, INR > 1.5 or presence of gastric varices were relative exclusion criteria. By random allocation 25 (group A) have received endoscopic sclerotherapy for esophageal varices alone and 22 (group B) combined treatment: esophagogastric devascularization with splenectomy followed by sclerotherapy. Interim analysis at 24 months has shown significant statistical differences between the groups and the randomization was halted.Results. Mean age was 38.9 ± 15.4 years and 58.46% were male. Mean follow-up was 38.6 ± 20.1 months. Endoscopic comparison of the size of esophageal varices before and after treatment did not show significant differences among the two groups. Treatment efficacy was assessed by the rate of recurrent esophageal variceal bleeding, that was more common in group A- 9/25 patients (36.0%) vs. 2/22 (9.0%) in group B (p = 0.029). Other complications were odynophagia, dysphagia and esophageal ulcer in group A and ascites and portal vein thrombosis in the surgical group.Conclusion. In portal hypertension due to schistosomiasis, combined surgical and endoscopic treatment was more effective for the prevention of recurrent esophageal variceal bleeding.
