RESUMO
BACKGROUND: Calcifying fibrous tumors (CFTs) are rare mesenchymal lesions that can occur in various sites throughout the body, including the tubular gastrointestinal (GI) tract. AIM: To analyze the clinical findings of 36 patients with GI tract CFTs to provide guidance for diagnosis and treatment. METHODS: This retrospective study included 36 patients diagnosed with CFTs of the GI tract. We collected demographic and clinical information and conducted regular follow-ups to assess for local recurrence. RESULTS: The stomach was the most commonly involved site, accounting for 72.2% of the 36 CFTs. Endoscopic mucosal resection (n = 1, 2.8%), endoscopic submucosal dissection (n = 14, 38.9%), endoscopic full-thickness resection (n = 16, 44.4%), and submucosal tunneling endoscopic resection (n = 5, 13.9%) were used to resect calcifying fibrous tumors. Overall, 34 (94.4%) CFTs underwent complete endoscopic resections with a mean procedure time of 39.8 ± 29.8 min. The average maximum diameter of the tumors was 10.6 ± 4.3 cm. No complications, such as bleeding or perforation, occurred during an average hospital stay of 2.9 ± 1.2 d. In addition, two patients developed new growth of CFTs near the primary tumor sites, and none of the patients developed distant metastases during the follow-up period. CONCLUSION: GI tract CFTs are rare and typically benign tumors that can be effectively managed with endoscopic procedures.
RESUMO
BACKGROUND: Endoscopic resection (ER) for jejunoileal lesions (JILs) has been technically challenging. We aimed to characterize the clinicopathologic characteristics, feasibility, and safety of ER for JILs. METHOD: We retrospectively investigated 52 patients with JILs who underwent ER from January 2012 to February 2022. We collected and analyzed clinicopathological characteristics, procedure-related parameters, outcomes, and follow-up data. RESULTS: The mean age was 49.4 years. Of the 52 JILs, 33 ileal tumors within 20 cm from the ileocecal valve were resected with colonoscopy, while 19 tumors in the jejunum or the ileum over 20 cm from the ileocecal valve received enteroscopy resection. The mean procedure duration was 49.0 min. The en bloc resection and en bloc with R0 resection rates were 86.5% and 84.6%, respectively. Adverse events (AEs) included one (1.9%) major AE (delayed bleeding) and five (9.6%) minor AEs. During a median follow-up of 36.5 months, two patients had local recurrence (3.8%), while none had metastases. The 5-year recurrence-free survival (RFS) and disease-specific survival (DSS) were 92.9% and 94.1%, respectively. Compared with the enteroscopy group, overall AEs were significantly lower in the colonoscopy group (P < 0.05), but no statistical differences were observed in RFS (P = 0.412) and DSS (P = 0.579). There were no significant differences in AEs, RFS, and DSS between the endoscopic submucosal dissection (ESD) and the endoscopic mucosal resection (EMR) group. CONCLUSIONS: ER of JILs has favorable short-term and long-term outcomes. Both ESD and EMR can safely and effectively resect JILs in appropriately selected cases.

Fe2+ has been commonly selected to activate peroxydisulfate(PDS) for sulfate radical(SO4-·) generation because of its eco-friendly, cost-effective, and high activity characteristics. However, Fe2+ can be rapidly oxidized to Fe3+ in the reaction, leading to poor utilization of iron for PDS activation. Further, a fairly high concentration of Fe2+ is generally required and may cause iron sludge production and secondary pollution. In this study, a minute Fe2+-activated PDS system induced by bisulfite(BS) was used to degrade paracetamol(APAP) in water. The results showed that the Fe2+-PDS system could be enhanced by the circulation of Fe2+-Fe3+ with the injection of BS and by keeping Fe2+ at a high concentration. Under the optimal conditions(PDS=0.6 mol·L-1; BS=0.4 mol·L-1; Fe2+=10 µmol·L-1; pH=4), 100% APAP(4 µmol·L-1) was removed within 180 s. The degradation rate of APAP increased with the increase in BS(0-0.6 mmol·L-1) and PDS(0.2-1.5 mmol·L-1) concentration, and a modest Fe2+ concentration could accelerate APAP removal. Co-existing substances inhibited the APAP removal and followed the order of HCO3->HPO42->Cl->NO3->humic acid(HA). Based on the quenching experiments and electron paramagnetic resonance spectroscopy test, SO4-· was shown to be the primary reactive species for APAP decomposition in the BS-Fe2+-PDS process. Three-dimensional fluorescence spectroscopy revealed that APAP intermediates had fluorescence characteristics. Moreover, five intermediates were identified, and the probable APAP degradation pathways were proposed. The removal efficiencies of APAP were lower in real waters than that in ultrapure water. Nevertheless, the removal effect was greatly improved after a prolonged reaction time. All results indicated that the BS-Fe2+-PDS system could be a promising method for organic pollutant treatment.
RESUMO
OBJECTIVES: Delayed bleeding is a rare but important major adverse event (mAE) after endoscopic submucosal tunneling procedures (ESTP), which is scarcely reported. We aimed to characterize the clinical characteristics of delayed bleeding and provide better management of this mAE. METHOD: From August 2010 to October 2022, we reviewed 3852 patients with achalasia receiving peroral endoscopic myotomy (POEM) and 1937 patients with upper gastrointestinal tumors receiving submucosal tunneling endoscopic resection (STER). Among these, records of 22 patients (15 POEM, 7 STER) with delayed bleeding were collected. Clinical characteristics, treatment, and outcomes of delayed bleeding were analyzed. RESULTS: The mean age was 43.6 years. Ten patients (45.5%) were intratunnel bleeding, seven (31.8%) were intratunnel bleeding accompanied by mucosal bleeding, and five (22.7%) were mucosal bleeding. The most common accompanied symptoms were hematemesis, fever, and melena. The most common accompanied mAEs were fistula, pulmonary inflammation, and pleural effusion with atelectasis. The mean duration from ESTP to endoscopic intervention was 5.3 ± 4.9 days. Active bleeding was identified in 21 patients (95.5%). The bleeding was successfully controlled by electrocoagulation (19 cases), endoscopic clipping (six cases), and Sengstaken-Blakemore tube insertion (three cases), and no patient required surgical intervention. The mean hemostatic procedure duration was 61.8 ± 45.8 min. The mean post-bleeding hospital stay was 10.0 ± 6.2 days. A brief meta-analysis of previous studies showed the pooled estimate delayed bleeding rate after POEM, STER, and G-POEM was 0.4%. CONCLUSIONS: Delayed bleeding is uncommon and could be effectively managed by timely emergency endoscopic procedures without requiring subsequent surgical interventions.

BACKGROUND AND AIMS: Stenosis after esophageal endoscopic submucosal dissection (ESD) has a high incidence, and muscular injury is an important risk factor for esophageal stenosis. Hence, this study aimed to classify muscular injury degrees and investigate their association with postoperative stenosis. METHODS: This retrospective study included 1033 patients with esophageal mucosal lesions treated with ESD between August 2015 and March 2021. Demographic and clinical parameters were analyzed, and stenosis risk factors were identified using multivariate logistic regression. A novel muscular injury classification system was proposed and used to investigate the association between different muscular injury degrees and postoperative stenosis. Finally, a scoring system was established to predict muscular injury. RESULTS: Of 1033 patients, 118 (11.4%) had esophageal stenosis. The multivariate analysis demonstrated that the history of endoscopic esophageal treatment, circumferential range, and muscular injury were significant risk factors for esophageal stenosis. Patients with type II muscular injuries tended to develop complex stenosis (n = 13 [36.1%], P < .05), and type II muscular injuries were more likely to predispose patients to severe stenosis than type I (73.3% and 92.3%, respectively). The scoring system showed that patients with high scores (3-6) were more likely to have muscular injury. The score model presented good discriminatory power in the internal validation (area under the receiver-operating characteristic curve, .706; 95% confidence interval, .645-.767) and goodness-of-fit in the Hosmer-Lemeshow test (P = .865). CONCLUSIONS: Muscular injury was an independent risk factor for esophageal stenosis. The scoring system demonstrated good performance in predicting muscular injury during ESD.

OBJECTIVES: Portal venous thrombosis (PVT) in cirrhotic patients is usually asymptomatic and diagnosed incidentally. In this study we aimed to investigate the prevalence and characteristics of advanced PVT in cirrhotic patients with a recent episode of gastroesophageal variceal hemorrhage (GVH). METHODS: Cirrhotic patients with recent GVH at one month before their admission for further treatment to prevent rebleeding were retrospectively recruited. Hepatic venous pressure gradient (HVPG) measurements, contrast-enhanced computed tomography (CT) scan of the portal vein system, and endoscopy were performed. PVT was diagnosed by CT examination and classified as none, mild and advanced. RESULTS: Of the 356 patients enrolled, 80 (22.5%) had advanced PVT. Elevated levels of white blood cells (WBC) and serum D-dimer were observed in advanced PVT patients compared with those with no or mild PVT. Moreover, HVPG was lower in patients with advanced PVT, with fewer patients having HVPG exceeding 12 mmHg, while grade III esophageal varices and varices with red signs were more prevalent. Multivariate analysis showed that WBC count (odds ratio [OR] 1.401, 95% confidence interval [CI] 1.171-1.676, P < 0.001), D-dimer level (OR 1.228, 95% CI 1.117-1.361, P < 0.001), HVPG (OR 0.942, 95% CI 0.900-0.987, P = 0.011), and grade III esophageal varices (OR 4.243, 95% CI 1.420-12.684, P = 0.010) were associated with advanced PVT. CONCLUSIONS: Advanced PVT, which is associated with a more severe hypercoagulable and inflammatory status, causes severe prehepatic portal hypertension in cirrhotic patients with GVH.

BACKGROUND AND AIMS: Reintervention modalities after myotomy failure in achalasia patients have yet to be established. The efficacy and safety of salvage peroral endoscopic myotomy (POEM) for treatment of achalasia after myotomy failure were evaluated in the study. METHODS: Between August 2011 and August 2021 at the Endoscopy Center of Zhongshan Hospital, 219 achalasia patients who had previously undergone a myotomy underwent a salvage POEM and were thus retrospectively enrolled in this study. After propensity score matching (PSM), operation-related parameters were compared between the salvage POEM group and the naïve POEM group. Subgroup analysis was performed between patients with previous Heller myotomy (HM) and patients with previous POEM. RESULTS: With similar baseline characteristics between both groups after PSM, the salvage POEM group presented with shorter tunnel length (11.8 ± 2.2 cm vs 12.8 ± .9 cm, P < .0001) and myotomy length (9.8 ± 2.0 cm vs 10.4 ± 1.0 cm, P < .0001) than the naïve POEM group. No significant differences were found in procedure-related adverse events between patients of salvage POEM and naïve POEM. The primary outcome of treatment success occurred in 175 of 193 patients (90.7%) in the salvage POEM group versus 362 of 374 patients (96.8%) in the naïve POEM group (P = .0046). At a 2- and 5-year follow-up, significantly higher rates of clinical failures were observed in the previous HM subgroup than in the previous POEM subgroup (P = .0433 and P = .0230, respectively). CONCLUSIONS: Salvage POEM after a previous myotomy failure, especially after a POEM failure, is a promising treatment option because it has a durable clinical relief rate.

OBJECTIVE: We aimed to investigate the prevalence of covert hepatic encephalopathy (CHE) in cirrhotic patients in China and its risk factors. METHODS: A multicenter prospective observational study was conducted from January 2021 to March 2022 at 16 medical centers across China to investigate the risk factors of CHE and establish a prediction model for CHE episodes. RESULTS: A total of 528 patients were enrolled in the study. Based on both the psychometric hepatic encephalopathy score and Stroop test results, the prevalence of CHE was 50.4% (266/528), and the consistency between these two tests was 68.9%. Multivariate analysis showed that age (odds ratio [OR] 1.043, 95% confidence interval [CI] 1.022-1.063, P < 0.001), duration of education (OR 0.891, 95% CI 0.832-0.954, P = 0.001), comorbidities of cardiovascular diseases, hypertension, cerebral apoplexy or diabetes mellitus (OR 2.072, 95% CI 1.370-3.133, P < 0.001), Child-Pugh score (OR 1.142, 95% CI 1.029-1.465, P = 0.025), and blood urea nitrogen concentration (OR 1.126, 95% CI 1.038-1.221, P = 0.004) were associated with CHE episodes. According to the Chronic Liver Disease Questionnaire, CHE patients had lower scores for abdominal symptoms and systemic symptoms (P < 0.001), indicating a poor health-related quality of life. Based on a stepwise Cox regression hazard model, we established a nomogram for determining the probabilities of CHE episodes, and the area under the receiver operating characteristic curve was 0.733 (95% CI 0.679-0.788) and 0.713 (95% CI 0.628-0.797) in the training and validation cohorts. CONCLUSIONS: CHE is a common complication of cirrhosis in China. Large-scale studies with long-term follow-up are needed to determine the natural history of Chinese CHE patients.

BACKGROUND AND AIMS: Peroral endoscopic myotomy (POEM) is a promising endoscopic technique for achalasia. We aimed to establish a regression model and develop a simple nomogram to predict the technical difficulty of POEM in a single center with large volume cases. METHODS: 3385 achalasia patients treated with POEM were included, and the technical difficulty was systemically evaluated. All of them were randomized into the training cohort (n = 1693) or internal validation cohort (n = 1692). Then, the prediction model and nomogram were proposed based on multivariate logistic regression analysis in the training cohort and assessed in the validation cohort. RESULTS: Of 3385 patients, technical difficulty happened in 417 (12.32%) cases. In the training stage, six factors were weighted based on the ß coefficient from the regression model, including age, disease duration, sigmoid esophagus, mucosal edema, submucosal fibrosis, and tunnel length. The patients were categorized into low-risk (< 0.1), medium-risk (0.1-0.25), and high-risk (> = 0.25) groups. Our score model performed satisfying discrimination with the areas under the receiver-operating characteristic curve (AUC) of 0.743 (95% confidence interval (CI), 0.701-0.785) and calibration with goodness of fit in the Hosmer-Lemeshow test (P = 0.088) in internal validation. CONCLUSIONS: The prediction model and nomogram demonstrated good performance in predicting the technical difficulty of POEM.

OBJECTIVES: Variceal hemorrhage is a fatal complication of cirrhosis. In this study, we aimed to investigate the role of serum interleukin 2 receptor (sIL-2R) as a predictive indicator in patients with a previous history of cirrhosis-related variceal bleeding. METHODS: A total of 340 cirrhotic patients who had experienced variceal bleeding from December 2016 to December 2018 were enrolled, and were randomly assigned to the modeling group and the validation group. The 3-year variceal rebleeding rate and other outcomes including adverse events were analyzed between patients with different sIL-2R levels. RESULTS: A time-dependent receiver operating characteristic (ROC) curve of variceal rebleeding indicated that sIL-2R had an area under the ROC curve (AUROC] of 0.731 and 0.837 for the modeling and validation groups, respectively, with a cut-off value of 426 U/mL. Kaplan-Meier analysis showed that higher sIL-2R level was related to an increased risk of variceal rebleeding rate (55.33% vs 24.34%, P = 0.024 and 51.28% vs 15.32%, P = 0.049) and decreased 3-year survival rate (91.16% vs 98.92%, P = 0.013 and 90.52% vs 97.50%, P = 0.180) in the modeling and validation groups. Elevated sIL-2R levels were associated with an increased risk of portal vein thrombosis and severe ascites as well as inferior liver function, hypercoagulable state, and increased portal pressure. CONCLUSION: High sIL-2R levels were associated with poor prognosis in cirrhotic patients with previous variceal bleeding.

BACKGROUND AND AIM: We aim to evaluate the efficacy and safety of endoscopic radial incision (ERI) versus endoscopic balloon dilation (EBD) treatment of naïve, recurrent, and refractory benign esophageal anastomotic strictures. METHODS: One hundred and one ERI, 145 EBD, and 42 ERI combined with EBD sessions were performed in 136 consecutive patients with benign esophageal anastomotic stricture after esophagectomy at Zhongshan Hospital from January 2016 to August 2021. Baseline characteristics, operational procedures, and clinical outcomes data were retrospectively evaluated. Parameters and recurrence-free survival (RFS) were compared between ERI and EBD in patients with naïve or recurrent or refractory strictures. Risk factors for re-stricture after ERI were identified using univariate and multivariate analyses. RESULTS: Twenty-nine ERI versus 68 EBD sessions were performed for naïve stricture, 26 ERI versus 60 EBD for recurrent strictures, and 46 ERI versus 17 EBD for refractory stricture. With comparable baseline characteristics, RFS was greater in the ERI than the EBD group for naïve strictures (P = 0.0449). The ERI group had a lower 12-month re-stricture rate than the EBD group (37.9% vs 61.8%, P = 0.0309) and a more prolonged patency time (181.5 ± 263.1 vs 74.5 ± 82.0, P = 0.0233). Between the two interventions, recurrent and refractory strictures had similar RFS (P = 0.0598; P = 0.7668). Multivariate analysis revealed initial ERI treatment was an independent predictive factor for lower re-stricture risk after ERI intervention (odds ratio = 0.047, P = 0.001). Few adverse events were observed after ERI or EBD (3.0% vs 2.1%, P = 0.6918). CONCLUSIONS: ERI is associated with lower re-stricture rates with better patency and RFS compared with EBD for naive strictures.

BACKGROUND AND AIMS: Endoscopic resection is a feasible treatment for GI extraluminal tumors but remains a challenging procedure with limited data. In this study, we assessed the safety and efficacy of endoscopic resection for extraluminal tumors in the upper GI tract. METHODS: From May 2016 to December 2021, 109 patients undergoing endoscopic resection for extraluminal tumors in the upper GI tract were retrospectively included. Clinicopathologic characteristics, procedure-related parameters, adverse events (AEs), and follow-up outcomes were analyzed. RESULTS: The en-bloc tumor resection rate was 94.5% and en-bloc retrieval rate 86.2%. Statistical analysis revealed tumor size ≥3.0 cm and irregular shape as significant risk factors for piecemeal extraction. Resection time and suture time were 46.8 ± 33.6 minutes and 20.6 ± 20.1 minutes, respectively. Large tumor size was significantly associated with a longer procedure duration. Five patients (4.6%) experienced major AEs, including recurrent laryngeal nerve injury, hydrothorax, major bleeding, local peritonitis, duodenal leakage, and repeat endoscopic surgery for tumor extraction. Minor AEs occurred in 13 patients (11.9%). Irregular tumor shape and tumor location (duodenum) were significantly associated with AE occurrence. Mean postoperative hospital stay was 4.7 ± 3.3 days. No recurrence or metastasis was observed during the mean follow-up period of 31.8 ± 15.2 months. CONCLUSIONS: Endoscopic resection is a safe and feasible therapeutic approach for upper GI extraluminal tumors. Tumor size, shape, and location impact the difficulty and safety of the procedure. Endoscopic resection of duodenal tumors is also feasible but associated with an increased risk of AEs compared with tumors in other locations.

OBJECTIVES: Gastric varices (GV), a common complication of liver cirrhosis, often cause serious consequences. However, the management of GV remains debated. In this study we aimed to explore the practice patterns of Chinese practitioners in GV treatment and discuss whether these patterns conform to the guidelines in China and around the world. METHODS: Between October 2020 and January 2021, an online questionnaire was sent to doctors from different regions in China via WeChat. Data on the practice patterns for endoscopic treatment with and without a multidisciplinary discussion team (MDT) clinic for GV were analyzed. RESULTS: Questionnaires were collected from 241 practitioners from 29 provinces in China. Before endoscopic treatment, 100 (41.5%) of the practitioners arranged computed tomography angiography (CTA) examination. In endoscopic tissue adhesive (ETA) treatment, 183 (75.9%) of the practitioners chose ETA combined with lauromacrogol. Approximately one-fourth of all practitioners did not prescribe drugs to reduce portal pressure. Only 75 (31.1%) of physicians preferred using early transjugular intrahepatic portosystemic shunt (TIPS) for patients at a high risk of treatment failure for GV. Compared to those without MDT clinics, practitioners with MDT clinics more often chose early TIPS for high-risk patients (39.0% vs 18.9%, P = 0.001). CONCLUSIONS: Treatment for GV differ across China. Practitioners with MDT clinics can better use assistant strategies such as CTA to evaluate the risk and efficacy. Further clinical studies are needed, and more guidelines and consensuses are warranted to standardize clinical practice for GV.

BACKGROUND AND AIMS: Submucosal tunneling endoscopic septum division (STESD) is an endoscopic minimally invasive technique for treating esophageal diverticulum. The objectives of this study were to evaluate the safety and efficacy of STESD and its impact on patients' quality of life. METHODS: This study included consecutive patients who underwent STESD for esophageal diverticulum from April 2016 to August 2020 in 2 centers (Zhongshan Hospital, Fudan University and Tianjin First Central Hospital). Esophagogram and endoscopic examination were performed before STESD and 30 days after STESD. Patients completed the 36-item Short Form survey (SF-36) before STESD and 1 year after surgery. Clinical symptoms were assessed via telehealth every 6 months until August 2021. Costamagna and Eckardt scores were used to evaluate changes in symptoms. RESULTS: Twenty-one patients were included. Mucosal injury 1 to 2 cm below the septum occurred in 2 patients. No severe surgical adverse events were observed. Median duration of follow-up was 39 months (range, 12-63). Total SF-36 scores increased from 118.7 ± 18.6 before STESD to 132.4 ± 9.1 at 1 year after the procedure (P = .007). SF-36 subscales of general health (P = .002), vitality (P = .004), social functioning (P = .030), and mental health (P = .020) improved significantly after STESD. The mean Costamagna score decreased from 3.83 ± 1.33 to 1.67 ± 1.51 (P = .010), whereas the mean Eckardt score decreased from 3.50 ± .90 to 1.25 ± 1.76 (P = .002). One patient developed symptom recurrence at 10 months after STESD. CONCLUSIONS: STESD is a safe and valid endoscopic minimally invasive surgery for esophageal diverticulum, which can reduce symptoms and improve quality of life.

RESUMO
Background and study aims Submucosal tunneling endoscopic resection (STER) and non-tunneling techniques are two alternative options for the treatment of cardial submucosal tumors (SMTs). We aimed to establish a regression model and develop a simple scoring system (Zhongshan Tunnel Score) to help clinicians make surgical decisions for cardial submucosal tumors. Patients and methods A total of 246 patients who suffered cardial SMTs and received endoscopic resection were included in this study. All of them were randomized into either the training cohort (nâ=â147) or the internal validation cohort (nâ=â99). Then, the scoring system was proposed based on multivariate logistic regression analysis in the training cohort and assessed in the validation cohort. Results Of 246 patients, 97 were treated with STER and the others with non-tunneling endoscopic resection. In the training stage, four factors were weighted with points based on the ß coefficient from the regression model, including irregular morphology (-2 points), ulcer (2 points), the direction of the gastroscope (-2 points for forward direction and 1 point for reverse direction), and originating from the muscularis propria (-2 points). The patients were categorized into low-score (<â-4), medium-score (-4 to -3) and high-score (>â-3) groups, and those with low scores were more likely to be treated with STER. Our score model performed satisfying discriminatory power in internal validation (Area under the receiver-operator characteristic curve, 0.829; 95â% confidence interval, 0.694-0.964) and goodness-of-fit in the Hosmer-Lemeshow test ( P â=â.4721). Conclusions This scoring system could provide clinicians the references for making decisions about the treatment of cardial submucosal tumors.
RESUMO
BACKGROUND: Submucosal tunneling endoscopic resection (STER) has been widely applied for esophageal submucosal tumors. This large volume study aims to provide a standard landscape of STER-related AEs for reference. METHODS: 1701 patients with esophageal SMTs undergoing STER were included at Zhongshan Hospital, Fudan University. Data of clinical characteristics and adverse events were collected and analyzed in depth. Adverse events were recorded by ASGE lexicon and graded by ASGE grading/Clavien-Dindo system. Risk factors for major AEs were analyzed by univariate and multivariate logistic regression. RESULTS: Three hundred and twenty (18.8%) patients with 962 cases of adverse events were observed. Accordingly, 84 (5.0%) were classified as major AEs (moderate and severe) by ASGE grading and 37 (2.2%) were classified as major AEs (grades III-V) by Clavien-Dindo grading. First 1 year operation, distance > 6 cm from incision to tumor, piecemeal resection, partially extraluminal location, mucosal injury, and operation time > 60 min were included in the risk score model for major AEs of STER, with 57.1% sensitivity and 87.5% specificity. CONCLUSIONS: STER was a safe procedure for diagnosis and treatment of esophageal SMTs with a total 18.8% incidence of AEs, among which only 5.0% were major AEs requiring therapeutic measurements.

BACKGROUND AND AIMS: Local recurrence of esophageal squamous cell carcinoma (ESCC) after endoscopic resection does not have an established treatment. The efficacy and safety of repeat endoscopic submucosal dissection (ESD) for recurrent ESCC were determined in the study. METHODS: Forty-three consecutive patients with 45 locally recurrent superficial ESCC lesions undergoing repeat ESD and 909 first ESD lesions for propensity score matching (PSM) at Zhongshan Hospital between January 2011 and January 2020 were retrospectively enrolled. After PSM (1:2), operation-related parameters were compared between repeat ESD and first ESD. In the repeat ESD group, the Kaplan-Meier method and log-rank tests were used for identification of risk factors for local recurrence after repeat ESD. RESULTS: As compared with propensity score-matched first ESD, rates of complete resection (86.7% vs 97.8%, P = .02) and curative resection (86.7% vs 96.7%, P = .06) were lower and procedure duration (54.8 ± 21.7 minutes vs 46.2 ± 20.6 minutes, P = .67) and hospital stay (4.3 ± 1.8 days vs 2.9 ± 1.4 days, P = .25) were longer in the repeat ESD group. The en-bloc resection rate (93.3% vs 98.8%, P > .11) remained comparable. Adverse events including bleeding (4.4% vs 0%, P = .11), perforation (.0% vs .0%, P > .99), and stricture (6.7% vs 2.2%, P = .33) presented with no difference. The 5-year overall survival rate and recurrence-free survival rate for repeat ESD was 100% and 86.0%, respectively. Multiplicity was significantly associated with recurrence after repeat ESD (P = .01). CONCLUSIONS: Repeat esophageal ESD showed favorable short- and long-term outcomes and thus provides an alternative choice for recurrent superficial ESCC.

OBJECTIVE: Helicobacter pylori infection is mostly a family-based infectious disease. To facilitate its prevention and management, a national consensus meeting was held to review current evidence and propose strategies for population-wide and family-based H. pylori infection control and management to reduce the related disease burden. METHODS: Fifty-seven experts from 41 major universities and institutions in 20 provinces/regions of mainland China were invited to review evidence and modify statements using Delphi process and grading of recommendations assessment, development and evaluation system. The consensus level was defined as ≥80% for agreement on the proposed statements. RESULTS: Experts discussed and modified the original 23 statements on family-based H. pylori infection transmission, control and management, and reached consensus on 16 statements. The final report consists of three parts: (1) H. pylori infection and transmission among family members, (2) prevention and management of H. pylori infection in children and elderly people within households, and (3) strategies for prevention and management of H. pylori infection for family members. In addition to the 'test-and-treat' and 'screen-and-treat' strategies, this consensus also introduced a novel third 'family-based H. pylori infection control and management' strategy to prevent its intrafamilial transmission and development of related diseases. CONCLUSION: H. pylori is transmissible from person to person, and among family members. A family-based H. pylori prevention and eradication strategy would be a suitable approach to prevent its intra-familial transmission and related diseases. The notion and practice would be beneficial not only for Chinese residents but also valuable as a reference for other highly infected areas.
