RESUMEN
BACKGROUND: Endoscopic resection of adenomas prevents colorectal cancer, but the optimal technique for larger lesions is controversial. Piecemeal endoscopic mucosal resection (EMR) has a low adverse event (AE) rate but a variable recurrence rate necessitating early follow-up. Endoscopic submucosal dissection (ESD) can reduce recurrence but may increase AEs. OBJECTIVE: To compare ESD and EMR for large colonic adenomas. DESIGN: Participant-masked, parallel-group, superiority, randomized controlled trial. (ClinicalTrials.gov: NCT03962868). SETTING: Multicenter study involving 6 French referral centers from November 2019 to February 2021. PARTICIPANTS: Patients with large (≥25 mm) benign colonic lesions referred for resection. INTERVENTION: The patients were randomly assigned by computer 1:1 (stratification by lesion location and center) to ESD or EMR. MEASUREMENTS: The primary end point was 6-month local recurrence (neoplastic tissue on endoscopic assessment and scar biopsy). The secondary end points were technical failure, en bloc R0 resection, and cumulative AEs. RESULTS: In total, 360 patients were randomly assigned to ESD (n = 178) or EMR (n = 182). In the primary analysis set (n = 318 lesions in 318 patients), recurrence occurred after 1 of 161 ESDs (0.6%) and 8 of 157 EMRs (5.1%) (relative risk, 0.12 [95% CI, 0.01 to 0.96]). No recurrence occurred in R0-resected cases (90%) after ESD. The AEs occurred more often after ESD than EMR (35.6% vs. 24.5%, respectively; relative risk, 1.4 [CI, 1.0 to 2.0]). LIMITATION: Procedures were performed under general anesthesia during hospitalization in accordance with the French health system. CONCLUSION: Compared with EMR, ESD reduces the 6-month recurrence rate, obviating the need for systematic early follow-up colonoscopy at the cost of more AEs. PRIMARY FUNDING SOURCE: French Ministry of Health.

INTRODUCTION: The environmental impact of endoscopy is a topic of growing interest. This study aimed to compare the carbon footprint of performing an esogastroduodenoscopy (EGD) with a reusable (RU) or with a single-use (SU) disposable gastroscope. METHODS: SU (Ambu aScope Gastro) and RU gastroscopes (Olympus, H190) were evaluated using life cycle assessment methodology (ISO 14040) including the manufacture, distribution, usage, reprocessing and disposal of the endoscope. Data were obtained from Edouard Herriot Hospital (Lyon, France) from April 2023 to February 2024. Primary outcome was the carbon footprint (measured in Kg CO2 equivalent) for both gastroscopes per examination. Secondary outcomes included other environmental impacts. A sensitivity analysis was performed to examine the impact of varying scenarios. RESULTS: Carbon footprint of SU and RU gastroscopes were 10.9 kg CO2 eq and 4.7 kg CO2 eq, respectively. The difference in carbon footprint equals one conventional car drive of 28 km or 6 days of CO2 emission of an average European household. Based on environmentally-extended input-output life cycle assessment, the estimated per-use carbon footprint of the endoscope stack and washer was 0.18 kg CO2 eq in SU strategy versus 0.56 kg CO2 eq in RU strategy. According to secondary outcomes, fossil eq depletion was 130 MJ (SU) and 60.9 MJ (RU) and water depletion for 6.2 m3 (SU) and 9.5 m3 (RU), respectively. CONCLUSION: For one examination, SU gastroscope have a 2.5 times higher carbon footprint than RU ones. These data will help with the logistics and planning of an endoscopic service in relation to other economic and environmental factors.
RESUMEN
INTRODUCTION: When initial resection of rectal neuroendocrine tumors (r-NETs) is not R0, persistence of local residue could lead to disease recurrence. This study aimed to evaluate the interest of systematic resection of non-R0 r-NET scars. METHODS: Retrospective analysis of all the consecutive endoscopic revisions and resections of the scar after non-R0 resections of r-NETs. RESULTS: A total of 100 patients were included. Salvage endoscopic procedure using endoscopic submucosal dissection or endoscopic full-thickness resection showed an R0 rate of near 100%. Residual r-NET was found in 43% of cases. DISCUSSION: In case of non-R0 resected r-NET, systematic scar resection by endoscopic full-thickness resection or endoscopic submucosal dissection seems necessary.

INTRODUCTION: The adoption of colorectal endoscopic submucosal dissection (ESD) is still limited in the West. A recent randomized trial showed that ESD is more effective and only slightly riskier than piecemeal endoscopic mucosal resection; reproducibility outside expert centers was questioned. We evaluated the results according to the annual case volume in a multicentric prospective cohort. METHODS: Between September 2019 and September 2022, colorectal ESD was consecutively performed at 13 participating centers classified as low volume (LV), middle volume (MV), and high volume (HV). The main procedural outcomes were assessed. Multivariate and propensity score matching analyses were performed. RESULTS: Three thousand seven hundred seventy ESDs were included. HV centers treated larger and more often colonic lesions than MV and LV centers. En bloc , R0, and curative resection rates were 95.2%, 87.4%, and 83.2%, respectively, and were higher at HV than at MV and LV centers. HV centers also achieved a faster dissection speed. Delayed bleeding and surgery for complications rates were 5.4% and 0.8%, respectively, without significant differences. The perforation rate (overall: 9%) was higher at MV than at LV and HV centers. Lesion characteristics, but not volume center, were independently associated with both R1 resection and perforation. However, after propensity score matching, R0 rates were significantly higher at HV than at LV centers, and perforation rates were significantly higher at MV than at HV centers. DISCUSSION: Colorectal ESD can be successfully implemented in the West, even in nonexpert centers. However, difficult lesions must still be referred to experts.
RESUMEN
BACKGROUND AND AIMS: We aimed to compare the long-term outcomes of patients with high-risk T1 colorectal cancer (CRC) resected endoscopically who received either additional surgery or surveillance. METHODS: We used data from routine care to emulate a target trial aimed at comparing 2 strategies after endoscopic resection of high-risk T1 CRC: surgery with lymph node dissection (treatment group) versus surveillance alone (control group). All patients from 14 tertiary centers who underwent an endoscopic resection for high-risk T1 CRC between March 2012 and August 2019 were included. The primary outcome was a composite outcome of cancer recurrence or death at 48 months. RESULTS: Of 197 patients included in the analysis, 107 were categorized in the treatment group and 90 were categorized in the control group. From baseline to 48 months, 4 of 107 patients (3.7%) died in the treatment group and 6 of 90 patients (6.7%) died in the control group. Four of 107 patients (3.7%) in the treatment group experienced a cancer recurrence and 4 of 90 patients (4.4%) in the control group experienced a cancer recurrence. After balancing the baseline covariates by inverse probability of treatment weighting, we found no significant difference in the rate of death and cancer recurrence between patients in the 2 groups (weighted hazard ratio, .95; 95% confidence interval, .52-1.75). CONCLUSIONS: Our study suggests that patients with high-risk T1 CRC initially treated with endoscopic resection may not benefit from additional surgery.

BACKGROUND AND AIMS: The muscle retracting sign (MRS) can be present during endoscopic submucosal dissection (ESD) of macronodular colorectal lesions. The prevalence of MRS and its pathologic and clinical implications is unclear. This study evaluated the effect of MRS on the technical and clinical outcomes of ESD. METHODS: All patients referred for ESD of protruding lesions or granular mixed lesions with >10 mm macronodule granular mixed laterally spreading tumors (LST-GMs) in 2 academic centers from January 2017 to October 2022 were prospectively included. Size of the macronodule was analyzed retrospectively. The primary outcome was the curative resection rate according to MRS status. Secondary outcomes were R0 resection, perforation, secondary surgery rate, and risk factors for MRS. RESULTS: Of 694 lesions, 84 (12%) had MRS (MRS+). The curative resection rate was decreased by MRS (MRS+ 41.6% vs lesions without MRS [MRS-] 81.3%), whereas the perforation (MRS+ 22.6% vs MRS- 9.2%), submucosal cancer (MRS+ 34.9% vs MRS- 9.2%), and surgery (MRS+ 45.2% vs MRS- 6%) rates were increased. The R0 resection rate of MRS+ colonic lesions was lower than that of rectal lesions (53% vs 74.3%). In multivariate analysis, protruding lesions (odds ratio, 2.47; 95% confidence interval, 1.27-4.80) and macronodules >4 cm (odds ratio, 4.24; 95% confidence interval, 2.23-8.05) were risk factors for MRS. CONCLUSIONS: MRS reduces oncologic outcomes and increases the perforation rate. Consequently, procedures in the colon should be stopped if MRS is detected, and those in the rectum should be continued due to the morbidity of alternative therapy.

BACKGROUND: The ileocecal valve (ICV) is considered to be one of the most difficult locations for endoscopic submucosal dissection (ESD). The objective of this study was to evaluate the efficacy and safety of traction-assisted ESD in this situation. METHODS: All patients who underwent traction-assisted ESD for an ICV lesion at three centers were identified from a prospective ESD database. En bloc and R0 rates were evaluated. Factors associated with non-R0 resection were explored. RESULTS: 106 patients with an ICV lesion were included. The median lesion size was 50 mm (interquartile range 38-60) and 58.5% (62/106) invaded the terminal ileum. The en bloc and R0 resection rates were 94.3% and 76.4%, respectively. Factors associated with non-R0 resection were lesions covering ≥75% of the ICV (odds ratio [OR] 0.21. 95%CI 0.06-0.76; P=0.02), and involving the anal lip (OR 0.36, 95%CI 0.13-0.99; P=0.04) or more than two sites on the ICV (OR 0.27, 95%CI 0.07-0.99; P=0.03). CONCLUSION: Traction-assisted ESD for treatment of ICV lesions was a safe and feasible option. Large lesions and anal lip involvement appeared to be factors predictive of difficulty.
RESUMEN
BACKGROUND: Clinically significant delayed bleeding (CSDB) is a frequent, and sometimes severe, adverse event after colorectal endoscopic submucosal dissection (ESD). We evaluated risk factors of CSDB after colorectal ESD. METHODS: We analyzed a prospective registry of 940 colorectal ESDs performed from 2013 to 2022. The incidence of bleeding was evaluated up to 30 days. Risk factors for delayed bleeding were evaluated by multivariate logistic regression. A Korean scoring model was tested, and a new risk-scoring model was developed and internally validated. RESULTS: CSDB occurred in 75 patients (8.0%). The Korean score performed poorly in our cohort, with a receiver operating characteristic (ROC) curve of 0.567. In the multivariate analysis, risk factors were age ≥75 years (odds ratio [OR] 1.63; 95%CI 0.97-2.73; 1 point), use of antithrombotics (OR 1.72; 95%CI 1.01-2.94; 1 point), rectal location (OR 1.51; 95%CI 0.92-2.48; 1 point), size >50 mm (OR 3.67; 95%CI 2.02-7.14; 3 points), and American Society of Anesthesiologists (ASA) score of III or IV (OR 2.26; 95%CI 1.32-3.92; 2 points). The model showed fair calibration and good discrimination, with an area under the ROC curve of 0.751 (95%CI 0.690-0.812). The score was used to define two groups of patients, those with low-medium risk (0 to 4 points) and high risk (5 to 8 points) for CSDB (respective bleeding rates 4.1% and 17.5%). CONCLUSION: A score based on five simple and meaningful variables was predictive of CSDB.

Malignant distal biliary obstructions are becoming increasingly common, especially in patients with cancers of the pancreatic head, despite progress in medical oncology research. ERCP is the current gold standard for management of such strictures, but the emergence of EC-LAMS has rendered EUS-CDS both safe and efficient. It is a "game changer"; originally intended for ERCP failure, two randomised clinical trials recently proposed EUS-CDS as a first-intent procedure in palliative settings. For resectable diseases, the absence of iatrogenic pancreatitis associated with a lower rate of postsurgical adverse events (compared with ERCP) leads us to believe that EUS-CDS might be used in first-intent as a pre-operative endoscopic biliary drainage.

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) is challenging for appendicular lesions. We report the outcomes of ESD in this context. METHODS: We collected data of ESD procedures for appendiceal neoplasia in a multicenter prospective registry. Main study endpoints were R0, en-bloc, and curative resection rates and adverse event rate. RESULTS: One hundred twelve patients were included, 47 (42%) with previous appendectomy. Fifty-six (50%) were Toyonaga type 3 lesions (15 [13.4%] postappendectomy). En-bloc and R0 resection rates were 86.6% and 80.4%, respectively, with no significant difference associated with different grades of appendiceal invasion (P = .9 and P = .4, respectively) or previous appendectomy (P = .3 for both). The curative resection rate was 78.6%. Additional surgery was performed in 16 cases (14.3%), including 10 (62.5%) Toyonaga type 3 lesions (P = .04). This included the treatment of 5 cases (4.5%) of delayed perforation and 1 acute appendicitis. CONCLUSIONS: ESD for appendicular lesions is a potentially safer and effective alternative to surgery for a significant proportion of patients.

BACKGROUND: Endoscopic submucosal dissection (ESD) is potentially a curative treatment for T1 colorectal cancer under certain conditions. The aim of this study was to evaluate the feasibility and effectiveness of ESD for lesions with a suspicion of focal deep invasion. METHODS: In this retrospective multicenter study, consecutive patients with colorectal neoplasia displaying a focal (< 15âmm) deep invasive pattern (FDIP) that were treated by ESD were included. We excluded ulcerated lesions (Paris III), lesions with distant metastasis, and clearly advanced tumors (tumoral strictures). RESULTS: 124 patients benefited from 126 diagnostic dissection attempts for FDIP lesions. Dissection was feasible in 120/126 attempts (95.2â%) and, where possible, the en bloc and R0 resection rates were 95.8â% (115/120) and 76.7â% (92/120), respectively. Thirty-three resections (26.2â%) were for very low risk tumors, so considered curative, and 38 (30.2â%) were for low risk lesions. Noncurative R0 resections were for lesions with lymphatic or vascular invasion (LVI; nâ=â8), or significant budding (nâ=â9), and LVIâ+âbudding combination (nâ=â4). CONCLUSION: ESD is feasible and safe for colorectal lesions with an FDIPâ≤â15âmm. It was curative in 26.6â% of patients and could be a valid option for a further 30.6â% of patients with low risk T1 cancers, especially for frail patients with co-morbidities.

BACKGROUND : The diagnosis of cholangiocarcinoma in patients with a biliary stricture without mass syndrome can be obtained by biliary brushing with a sensitivity of ~50â%. We performed a multicenter randomized crossover trial comparing the aggressive Infinity brush with the standard RX Cytology Brush. The aims were to compare sensitivity for cholangiocarcinoma diagnosis and cellularity obtained. METHODS : Biliary brushing was performed consecutively with each brush, in a randomized order. Cytological material was studied with blinding to the brush type used and order. The primary end point was sensitivity for cholangiocarcinoma diagnosis; the secondary end point was the abundance of cellularity obtained with each brush, with cellularity quantified in order to determine if one brush strongly outperformed the other. RESULTS : 51 patients were included. Final diagnoses were cholangiocarcinoma (nâ=â43; 84â%), benign (nâ=â7; 14â%), and indeterminate (nâ=â1; 2â%). Sensitivity for cholangiocarcinoma was 79â% (34â/43) for the Infinity brush versus 67â% (29/43) for the RX Cytology Brush (Pâ=â0.10). Cellularity was rich in 31/51 cases (61â%) with the Infinity brush and in 10/51 cases (20â%) with the RX Cytology Brush (Pâ<â0.001). In terms of quantification of cellularity, the Infinity brush strongly outperformed the RX Cytology Brush in 28/51 cases (55â%), while the RX Cytology Brush strongly outperformed the Infinity brush in 4/51 cases (8â%; Pâ<â0.001). CONCLUSIONS : This randomized crossover trial showed that the Infinity brush is not significantly more effective than the RX Cytology Brush for biliary stenosis without mass syndrome in terms of sensitivity for cholangiocarcinoma diagnosis, but does offer a significantly higher abundance of cellularity.

BACKGROUND: Liver cirrhosis and esophageal cancer share several risk factors, such as alcohol intake and excess weight. Endoscopic resection is the gold standard treatment for superficial tumors. Portal hypertension and coagulopathy may increase the bleeding risk in these patients. This study aimed to assess the safety and efficacy of endoscopic resection for early esophageal neoplasia in patients with cirrhosis or portal hypertension. METHODS: This retrospective multicenter international study included consecutive patients with cirrhosis or portal hypertension who underwent endoscopic resection in the esophagus from January 2005 to March 2021. RESULTS: 134 lesions in 112 patients were treated, including by endoscopic submucosal dissection in 101 cases (75â%). Most lesions (128/134, 96â%) were in patients with liver cirrhosis, with esophageal varices in 71 procedures. To prevent bleeding, 7 patients received a transjugular intrahepatic portosystemic shunt, 8 underwent endoscopic band ligation (EBL) before resection, 15 received vasoactive drugs, 8 received platelet transfusion, and 9 underwent EBL during the resection procedure. Rates of complete macroscopic resection, en bloc resection, and curative resection were 92â%, 86â%, and 63â%, respectively. Adverse events included 3 perforations, 8 delayed bleedings, 8 sepsis, 6 cirrhosis decompensations within 30 days, and 22 esophageal strictures; none required surgery. In univariate analysis, cap-assisted endoscopic mucosal resection was associated with delayed bleeding (Pâ=â0.01). CONCLUSIONS: In patients with liver cirrhosis or portal hypertension, endoscopic resection of early esophageal neoplasia appeared to be effective and should be considered in expert centers with choice of resection technique, following European Society of Gastrointestinal Endoscopy guidelines to avoid undertreatment.

INTRODUCTION : Residual colorectal neoplasia (RCN) after previous endoscopic mucosal resection is a frequent challenge. Different management techniques are feasible including endoscopic full-thickness resection using the full-thickness resection device (FTRD) system and endoscopic submucosal dissection (ESD). We aimed to compare the efficacy and safety of these two techniques for the treatment of such lesions. METHODS : All consecutive patients with RCN treated either using the FTRD or by ESD were retrospectively included in this multicenter study. The primary outcome was the R0 resection rate, defined as an en bloc resection with histologically tumor-free lateral and deep margins. RESULTS : 275 patients (median age 70 years; 160 men) who underwent 177 ESD and 98 FTRD procedures for RCN were included. R0 resection was achieved in 83.3â% and 77.6â% for ESD and FTRD, respectively (Pâ=â0.25). Lesions treated by ESD were however larger than those treated by FTRD (Pâ<â0.001). The R0 rates for lesions of 20-30âmm were 83.9â% and 57.1â% in the ESD and FTRD groups, respectively, and for lesions of 30-40âmm were 93.6â% and 33.3â%, respectively. On multivariable analysis, ESD procedures were associated with statistically higher en bloc and R0 resection rates after adjustment for lesion size (Pâ=â0.02 and Pâ<â0.001, respectively). The adverse event rate was higher in the ESD group (16.3â% vs. 5.1â%), mostly owing to intraoperative perforations. CONCLUSION: ESD is effective in achieving R0 resection for RCN whatever the size and location of the lesions. When residual lesions are smaller than 20âmm, the FTRD is an effective alternative.

BACKGROUND & AIMS: We developed and validated a magnetic resonance imaging-based index to predict Crohn's disease (CD) postoperative recurrence (POR). METHODS: Patients with CD who underwent a postoperative evaluation for recurrence (with colonoscopy and MRI no longer than 105 days apart) were included between 2006 and 2016 in University Hospital of Nancy, France. MRI items with good levels of intra-rater and inter-rater agreement (Gwet's coefficient ≥0.5) were selected. The MRI in Crohn's Disease to Predict Postoperative Recurrence (MONITOR) index's performance was assessed in terms of the area under the receiver operating characteristic curve (AUROC) and accuracy, by considering the Rutgeerts score as the gold standard. The MONITOR index was validated with a bootstrap method and an independent cohort. RESULTS: Seventy-three MRI datasets were interpreted by 2 radiologists. Seven items (bowel wall thickness, contrast enhancement, T2 signal increase, diffusion-weighted signal increase, edema, ulcers, and the length of the diseased segment) had a Gwet's coefficient ≥0.5 and were significantly associated with the Rutgeerts score, leading to their inclusion in the MONITOR index. All the items had a weighting of 1, except the "ulcers" item weighting 2.5, reflecting the higher adjusted odds ratio. The AUROC [95% confidence interval] for the prediction of endoscopic POR (Rutgeerts score >i1) was 0.80 [0.70-0.90]. The optimal threshold was a MONITOR index ≥1, giving a sensitivity of 79%, a specificity of 55%, a predictive positive value of 68%, and a predictive negative value of 68%. The bootstrap validation gave an AUROC of 0.85 [0.73-0.97]. In the validation cohort, a MONITOR index ≥1 gave a sensitivity of 87%, a specificity of 75%, a predictive positive value of 84.6%, and a predictive negative value of 75%. CONCLUSIONS: The MONITOR index is an efficient, reliable, easy-to-apply tool that can be used in clinical practice to predict the POR of CD.

OBJECTIVES: Endoscopic ultrasound-guided digestive anastomosis (EUS-A) is a new alternative under evaluation in patients presenting with afferent limb syndrome (ALS) after Whipple surgery. The aim of the present study is to analyze the safety and effectiveness of EUS-A in ALS. METHODS: This is an observational multicenter study. All patients ≥18 years old with previous Whipple surgery presenting with ALS who underwent an EUS-A using a lumen-apposing metal stent (LAMS) between 2015 and 2021 were included. The primary outcome was clinical success, defined as resolution of the ALS or ALS-related cholangitis. Furthermore, technical success, adverse event rate, and mortality were evaluated. RESULTS: Forty-five patients (mean age: 65.5 ± 10.2 years; 44.4% male) were included. The most common underlying disease was pancreatic cancer (68.9%). EUS-A was performed at a median of 6 weeks after local tumor recurrence. The most common approach used was the direct/freehand technique (66.7%). Technical success was achieved in 95.6%, with no differences between large (≥15 mm) and small LAMS (97.4% vs. 100%, P = 0.664). Clinical success was retained in 91.1% of patients. A complementary treatment by dilation of the stent followed by endoscopic retrograde cholangiopancreatography through the LAMS was performed in three cases (6.7%). There were six recurrent episodes of cholangitis (14.6%) and two procedure-related adverse events (4.4%) after a median follow-up of 4 months. Twenty-six patients (57.8%) died during the follow-up due to disease progression. CONCLUSION: EUS-A is a safe and effective technique in the treatment of malignant ALS, achieving high clinical success with an acceptable recurrence rate.

INTRODUCTION: The aims of this retrospective multicenter study were to assess the technical success and adverse events of endoscopic retrograde cholangiopancreatography (ERCP) procedures in children in French and Belgian centers. METHODS: All children aged 1 day to 17 years who underwent ERCP between January 2008 and March 2019 in 15 tertiary care hospitals were retrospectively included. RESULTS: 271 children underwent 470 ERCP procedures. Clinical long-term follow-up was available for 72â% of our patients (340/470 procedures). The median age at intervention was 10.9 years. ERCP was therapeutic in 90â% (423/470) and diagnostic in cases of neonatal cholestasis in 10â% of the patients. The most common biliary indication was choledocholithiasis; the most common pancreatic indication was chronic pancreatitis. Biliary cannulation was successful in 92â% of cases (270/294); pancreatic cannulation in 96â% of cases (169/176); and planned therapeutic procedures in 92â% of cases (388/423). The overall complication rate was 19â% (65/340). The most common complication was post-ERCP pancreatitis (PEP) in 12â% of cases (40/340) and sepsis in 5â% (18/340). On univariate analyses, pancreatic stent removal was protective against PEP (odds ratio [OR] 0.1, 95â% confidence interval [CI] 0.01â-â0.75; Pâ=â0.03), and sepsis was associated with history of liver transplantation (OR 7.27, 95â%CI 1.7â-â31.05; Pâ=â0.01). Five patients had post-ERCP hemorrhage and two had intestinal perforation. All complications were managed with supportive medical care. There was no procedure-related mortality. CONCLUSION: Our cohort demonstrates that ERCP can be performed safely with high success rates in many pancreaticobiliary diseases of children. The rate of adverse events was similar to that in previous reports.
