RESUMEN
BACKGROUND: Several endoscopic treatments for iatrogenic perforations are currently available, with some limitations in terms of size, location, complexity, or cost. Our aims were to introduce a novel technique for closure, using an endoloop and clips, to assess its rate of technical success and post-resection complications. METHODS: For closure of large perforations (diameter ≥ 10 mm), two similar techniques were implemented, using a single-channel endoscope. An endoloop was deployed through the operating channel or towed by an endoclip alongside the endoscope. Several clips were utilized to fix it on the muscular layer of defect's margins. The defect was closed, by fastening the loop either directly or after being reattached to the mobile hook. RESULTS: This analysis included eleven patients (72% women, median age 68 years). Eight colorectal, one appendiceal, and two gastric lesions were resected, with a median perforation size of 15 mm. As confirmed by computed tomography, closure of wall defects was achieved successfully in all cases, using a median of 6 clips. Pneumoperitoneum was evacuated in 4 cases. The median hospitalization duration was 4 days, prophylactic antibiotics being prescribed for a median of 7 days. One patient had a small abdominal collection, without requiring drainage, while another presented post-resection bleeding from the mucosal defect. CONCLUSION: The novel techniques, utilizing a single-channel endoscope, clips, and an endoloop, ensuring an edge-to-edge suture of muscular layer, proved to be safe, reproducible, and easy to implement. They exhibit an excellent technical success rate and a minimal incidence of non-severe complications.

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.

BACKGROUND AND AIMS: Ampullary lesions (ALs) of the minor duodenal papilla are extremely rare. Endoscopic papillectomy (EP) is a routinely used treatment for AL of the major duodenal papilla, but the role of EP for minor AL has not been accurately studied. METHODS: We identified 20 patients with ALs of minor duodenal papilla in the multicentric database from the Endoscopic Papillectomy vs Surgical Ampullectomy vs Pancreatitcoduodenectomy for Ampullary Neoplasm study, which included 1422 EPs. We used propensity score matching (nearest-neighbor method) to match these cases with ALs of the major duodenal papilla based on age, sex, histologic subtype, and size of the lesion in a 1:2 ratio. Cohorts were compared by means of chi-square or Fisher exact test as well as Mann-Whitney U test. RESULTS: Propensity score-based matching identified a cohort of 60 (minor papilla 20, major papilla 40) patients with similar baseline characteristics. The most common histologic subtype of lesions of minor papilla was an ampullary adenoma in 12 patients (3 low-grade dysplasia and 9 high-grade dysplasia). Five patients revealed nonneoplastic lesions. Invasive cancer (T1a), adenomyoma, and neuroendocrine neoplasia were each found in 1 case. The rate of complete resection, en-bloc resection, and recurrences were similar between the groups. There were no severe adverse events after EP of lesions of minor papilla. One patient had delayed bleeding that could be treated by endoscopic hemostasis, and 2 patients showed a recurrence in surveillance endoscopy after a median follow-up of 21 months (interquartile range, 12-50 months). CONCLUSIONS: EP is safe and effective in ALs of the minor duodenal papilla. Such lesions could be managed according to guidelines for EP of major duodenal papilla.

Background and Objectives: Pancreatic cyst fluid level of glucose is a promising marker to identify mucinous from nonmucinous tumors, but the glucose assay has not yet been recommended. The objective of this study is to compare the diagnostic performances of pancreatic cyst fluid level of glucose and carcinoembryonic antigen (CEA). Methods: In this French multicenter study, data of consecutive patients who underwent fine-needle aspiration of pancreatic cyst with intracyst glucose assay between 2018 and 2022 were retrospectively reviewed. The area under the receiver operating characteristic curve (AUROC) of glucose and corresponding sensitivity (Se), specificity (Sp), accuracy (Acc), positive predictive value (PPV), and negative predictive value (NPV) were calculated and compared with those of CEA. The best threshold of glucose was identified using the Youden index. Results: Of the 121 patients identified, 81 had a definitive diagnosis (46 mucinous, 35 nonmucinous tumors) and were included for analysis. An intracystic glucose level <41.8 mg/dL allowed identification of mucinous tumors with better diagnostic performances (AUROC, 93.6%; 95% confidence interval, 87.2%-100%; Se, 95.3%; Sp, 91.2%; Acc, 93.5%; PPV, 93.2%; NPV, 93.9%) compared with CEA level >192 ng/mL (AUROC, 81.2%; 95% confidence interval, 71.3%-91.1%; Se, 41.7%; Sp, 96.9%; Acc, 67.6%; PPV, 93.8%; NPV, 59.6%) (P = 0.035). Combining values of glucose and CEA did not offer additional benefit in terms of diagnosis. Conclusion: Our results confirm previously published data and support the use of pancreatic cyst fluid glucose for the identification of mucinous tumors when the definitive diagnosis remains uncertain.
RESUMEN
PATIENTS AND METHODS: we performed a retrospective case-control study, including cases with repeat EUS FNB for a solid pancreatic lesion, matched on a 1:2 ratio on age, sex, tumor location and presence of chronic pancreatitis with cases diagnosed on the first EUS FNB. RESULTS: thirty-four cases and 68 controls were included in the analysis. Diagnostic accuracies were 80% and 88% in the repeat and single EUS FNB groups, respectively (p = 0.824). The second EUS FNB had a sensitivity of 80%, a specificity of 75%, a positive predictive value of 96%, and a negative predictive value of 33%. Of the 34 patients in the repeat EUS FNB group, 25 (74%) had a positive diagnosis with the second EUS FNB, 4 (12%) after surgery due to a second negative EUS FNB, 4 (12%) during clinical follow-up, and 1 (3%) after a third EUS FNB. Of the 25 patients diagnosed on the repeat EUS FNB, 17 (68%) had pancreatic adenocarcinomas, 2 (8%) neuroendocrine tumors, 2 (8%) other autoimmune pancreatitis, 2 (8%) chronic pancreatitis nodules, 1 (4%) renal cancer metastasis, and 1 (4%) other malignant diagnostic. There were no complications reported after the second EUS FNB in this study. CONCLUSION: repeat EUS FNB made a diagnosis in three fourths of patients with solid pancreatic lesions and a first negative EUS FNB, with 26% of benign lesions. This supports the repetition of EUS FNB sampling in this clinical situation.
RESUMEN
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.

INTRODUCTION: Ampullary neuroendocrine neoplasia (NEN) is rare and evidence regarding their management is scarce. This study aimed to describe clinicopathological features, management, and prognosis of ampullary NEN according to their endoscopic or surgical management. METHODS: From a multi-institutional international database, patients treated with either endoscopic papillectomy (EP), transduodenal surgical ampullectomy (TSA), or pancreaticoduodenectomy (PD) for ampullary NEN were included. Clinical features, post-procedure complications, and recurrences were assessed. RESULTS: 65 patients were included, 20 (30.8%) treated with EP, 19 (29.2%) with TSA, and 26 (40%) with PD. Patients were mostly asymptomatic (n = 46; 70.8%). Median tumor size was 17 mm (12-22), tumors were mostly grade 1 (70.8%) and pT2 (55.4%). Two (10%) EP resulted in severe American Society for Gastrointestinal Enterology (ASGE) adverse post-procedure complications and 10 (50%) were R0. Clavien 3-5 complications did not occur after TSA and in 4, including 1 postoperative death (15.4%) of patients after PD, with 17 (89.5%) and 26 R0 resection (100%), respectively. The pN1/2 rate was 51.9% (n = 14) after PD. Tumor size larger than 1 cm (i.e., pT stage >1) was a predictor for R1 resection (p < 0.001). Three-year overall survival and disease-free survival after EP, TSA, and PD were 92%, 68%, 92% and 92%, 85%, 73%, respectively. CONCLUSION: Management of ampullary NEN is challenging. EP should not be performed in lesions larger than 1 cm or with a endoscopic ultrasonography T stage beyond T1. Local resection by TSA seems safe and feasible for lesions without nodal involvement. PD should be preferred for larger ampullary NEN at risk of nodal metastasis.

BACKGROUND: Endoscopic techniques allow resections of deep submucosal invasion rectal carcinoma, but mostly are facing issues such as costs, follow-up care or size limit. Our aim was to design a new endoscopic technique, which retains the advantages over surgical resections while eliminating the disadvantages mentioned above. PATIENTS AND METHODS: We propose a technique for the resection of the superficial rectal tumours, with highly suspicious deep submucosal invasion. It combines steps of endoscopic submucosal dissection, muscular resection and edge-to-edge suture of the muscular layers, finally performing the equivalent of a "transanal endoscopic microsurgery" with a flexible colonoscope (F-TEM). RESULTS: A 60-year-old patient was referred to our unit, following the discovery of a 15 mm distal rectum adenocarcinoma. The computed tomography and the endoscopic ultrasound examination revealed a T1 tumour, without secondary lesions. Considering that the initial endoscopic evaluation highlighted a depressed central part of the lesion, with several avascular zones, an F-TEM was performed, without severe complication. The histopathological examination revealed negative resection margins, without risk factors for lymph node metastasis, no adjuvant therapy being proposed. CONCLUSION: F-TEM allows endoscopic resection of highly suspicious deep submucosal invasion T1 rectal carcinoma and it proves to be a feasible alternative to surgical resection or other endoscopic treatments as endoscopic submucosal dissection or intermuscular dissection.

Background and study aims Esophageal stricture is the most frequent adverse event after endoscopic resection for early esophageal neoplasia. Currently available treatments for the prevention of esophageal stricture are poorly effective and associated with major adverse events. Our aim was to identify transcripts specifically overexpressed or repressed in patients who have developed a post-endoscopic esophageal stricture, as potential targets for stricture prevention. Patients and methods We conducted a prospective single-center study in a tertiary endoscopy center. Patients scheduled for an endoscopic resection and considered at risk of esophageal stricture were offered inclusion in the study. The healthy mucosa and resection bed were biopsied on Days 0, 14, and 90. A transcriptomic analysis by microarray was performed, and the differences in transcriptomic profile compared between patients with and without esophageal strictures. Results Eight patients, four with esophageal stricture and four without, were analyzed. The mean ± SD circumferential extension of the mucosal defect was 85â±â11â%. The transcriptomic analysis in the resection bed at day 14 found an activation of the interleukin (IL)-1 group (Z scoreâ=â2.159, P â=â0.0137), while interferon-gamma (INFγ) and NUPR1 were inhibited (Z scoreâ=â-2.375, P â=â0.0022 and Z scoreâ=â-2.333, P â=â0.00131) in the stricture group.âNone of the activated or inhibited transcripts were still significantly so in any of the groups on Day 90. Conclusions Our data suggest that IL-1 inhibition or INFγ supplementation could constitute promising targets for post-endoscopic esophageal stricture prevention.
RESUMEN
BACKGROUND: Familial adenomatous polyposis (FAP) is a rare inherited syndrome that predisposes the patient to cancer. Treatment of FAP-related ampullary lesions is challenging and the role of endoscopic papillectomy has not been elucidated. We retrospectively analyzed the outcomes of endoscopic papillectomy in matched cohorts of FAP-related and sporadic ampullary lesions (SALs). METHODS: This retrospective multicenter study included 1422 endoscopic papillectomy procedures. Propensity score matching including age, sex, comorbidity, histologic subtype, and size was performed. Main outcomes were complete resection (R0), technical success, complications, and recurrence. RESULTS: Propensity score matching identified 202 patients (101 FAP, 101 SAL) with comparable baseline characteristics. FAP patients were mainly asymptomatic (79.2â% [95â%CI 71.2-87.3] vs. 46.5â% [95â%CI 36.6-56.4]); Pâ<â0.001). The initial R0 rate was significantly lower in FAP patients (63.4â% [95â%CI 53.8-72.9] vs. 83.2â% [95â%CI 75.8-90.6]; Pâ=â0.001). After repeated interventions (mean 1.30 per patient), R0 was comparable (FAP 93.1â% [95â%CI 88.0-98.1] vs. SAL 97.0â% [95â%CI 93.7-100]; Pâ=â0.19). Adverse events occurred in 28.7â%. Pancreatitis and bleeding were the most common adverse events in both groups. Severe adverse events were rare (3.5â%). Overall, 21 FAP patients (20.8â% [95â%CI 12.7-28.8]) and 16 SAL patients (15.8â% [95â%CI 8.6-23.1]; Pâ=â0.36) had recurrence. Recurrences occurred later in FAP patients (25 [95â%CI 18.3-31.7] vs. 2 [95â%CI CI 0.06-3.9] months). CONCLUSIONS: Endoscopic papillectomy was safe and effective in FAP-related ampullary lesions. Criteria for endoscopic resection of ampullary lesions can be extended to FAP patients. FAP patients have a lifetime risk of relapse even after complete resection, and require long-time surveillance.

INTRODUCTION: Radiofrequency ablation (RFA) has become the recommended endoscopic treatment for flat dysplastic Barrett's esophagus. However, the outcomes of this treatment are variable across European countries. Our aim was to report the results of a French high-volume center, and to investigate factors associated with treatment failure. METHODS: We conducted a single-center retrospective study from a prospectively collected database from 2011 to 2020, including all consecutive patients treated with RFA for flat dysplastic Barrett's esophagus. The primary endpoint was the failure rate of esophageal radiofrequency treatment, defined as either persistence of intestinal metaplasia at the end of treatment, or neoplastic progression during RFA. RESULTS: 96 patients treated with a median of four RFA sessions for a mean C5M6 Barrett's esophagus were included in the analysis. Complete eradication of intestinal metaplasia and dysplasia were achieved in 59% and 79% of patients, respectively, resulting in a treatment failure rate of 41%. Ten patients experienced neoplastic progression during treatment. We recorded 14% of post-RFA esophageal strictures, all successfully treated by endoscopic dilatation. Univariate analysis identified the length of Barrett's esophagus and the absence of hiatal hernia as predictive factors for treatment failure, however not confirmed in multivariate analysis. CONCLUSION: In our experience, RFA of flat dysplastic Barrett's esophagus had a 41% treatment failure rate. The length of the Barrett's segment might be associated with treatment failure. Although our results confirm a role for RFA in the management of dysplastic Barrett's esophagus, the treatment failure rate was higher than expected. This suggest that endoscopists, even in high-volume centers, should receive specific training in RFA.

Background and study aims Evidence for the modes of transmission of SARS-CoV-2 remains controversial. Recently, the potential for airborne spread of SARS-CoV-2 has been stressed. Air circulation in gastrointestinal light source boxes and endoscopes could be implicated in airborne transmission of microorganisms. Methods The ENDOBOX SC is a 600â×â600âmm cube designed to contain any type of machine used during gastrointestinal endoscopy. It allows for a 100-mm space between a machine and the walls of the ENDOBOX SC. To use the ENDOBOX SC, it is connected to the medical air system and it provides positive flow from the box to the endoscopy room. The ENDOBOX SC uses medical air to inflate the digestive tract and to decrease the temperature induced by the microprocessors or by the lamp.âENDOBOX SC has been investigated in different environments. Results An endoscopic procedure performed without ventilation was interrupted after 40 minutes to prevent computer damage. During the first 30 minutes, the temperature increased from 18â°C to 31â°C with a LED system. The procedure with fans identified variations in temperature inside the ENDOBOX SC from 21 to 26â°C (±â5â°C) 1 hour after the start of the procedure. The temperature was stable for the next 3 hours. Conclusions ENDOBOX SC prevents the increase in temperature induced by lamps and processors, allows access to all necessary connections into the endoscopic columns, and creates a sterile and positive pressure volume, which prevents potential contamination from microorganisms.
RESUMEN
Aggressive intrasegmental recurrence (AIR) is a form of local recurrence associated with a dismal prognosis and defined by multiple nodules or by an infiltrative mass with a tumor thrombus, occurring in the treated segment, after radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). We aimed to identify radiological and/or histological characteristics of tumor biopsy predictive of AIR. We retrospectively analyzed patients treated by No-Touch multi-bipolar RFA (mbpRFA) for a first HCC with a systematic per-procedural tumor biopsy positive for diagnosis of HCC. The first recurrence was classified as non-aggressive local recurrence, AIR or intrahepatic distant recurrence. 212 patients were included (168 men; mean age 67.1 years; mean tumor size 28.6 mm, 181 cirrhosis). AIR occurred in 21/212 patients (10%) and was associated with a higher risk of death (57% in patients with AIR vs 30% without AIR, p = 0.0001). Non-smooth tumor margins, observed in 21% of the patients and macro-trabecular massive histological subtype, observed in 12% of the patients were independently related to a higher risk of AIR (HR: 3.7[1.57;9.06], p = 0.002 and HR:3.8[2.47;10], p = 0.005 respectively). Non smooth margins at imaging and macro-trabecular massive histological subtype are associated with AIR and could be considered as aggressive features useful to stratify therapeutic strategy.

Pancreatic neuroendocrine tumors (p-NETs) are rare tumors with a recent growing incidence. In the 2017 WHO classification, p-NETs are classified into well-differentiated (i.e., p-NETs grade 1 to 3) and poorly differentiated neuroendocrine carcinomas (i.e., p-NECs). P-NETs G1 and G2 are often non-functioning tumors, of which the prognosis depends on the metastatic status. In the localized setting, p-NETs should be surgically managed, as no benefit for adjuvant chemotherapy has been demonstrated. Parenchymal sparing resection, including both duodenum and pancreas, are safe procedures in selected patients with reduced endocrine and exocrine long-term dysfunction. When the p-NET is benign or borderline malignant, this surgical option is associated with low rates of severe postoperative morbidity and in-hospital mortality. This narrative review offers comments, tips, and tricks from reviewing the available literature on these different options in order to clarify their indications. We also sum up the overall current data on p-NETs G1 and G2 management.

Background and study aims Per oral endoscopic myotomy (POEM) of the lower esophageal sphincter has become a major treatment for esophageal motility disorders, especially achalasia. POEM can result in esophageal bleeding or perforation and pleural and mediastinal effusion. Early routine computed tomography (CT) esophagogram is frequently performed to assess these adverse events (AEs) before resuming oral food intake. We sought to evaluate the value of routine CT esophagogram on postoperative day (POD) 1 after POEM. Patients and methods This single-center retrospective study was performed in a tertiary referral center for interventional digestive endoscopy. We included consecutive patients with POEM and routine CT esophagogram on POD 1 between July 2018 and July 2019. Results Fifty-eight patients were included in the study, 79â% of whom had achalasia. Twenty patients (34â%) presented post-endoscopic AEs, including two patients with severe AEs requiring intensive care admission (one compressive pneumothorax and one mediastinitis); no deaths occurred. Of the 58 CT esophagograms performed, only one was normal. The 57 others (98â%) showed at least one abnormal finding: pneumoperitoneum or retroperitoneal air (91â%), pneumomediastinum (78â%), pleural effusion (34â%), pneumothorax (14â%), pneumonia (7â%), pericardial effusion (2â%), and mediastinal collection (2â%). CT esophagograms revealed AEs and modified therapeutic management in eight patients of 58 (14â%), all of whom had clinical symptoms prior to CT. Conclusions POD 1 CT esophagogram after POEM for esophageal motility disorders diagnosed clinically meaningful AEs in 14â% of patients, all associated with persistent clinical symptoms. Routine use of CT esophagogram after POEM in asymptomatic patients is questionable.
RESUMEN
BACKGROUND: This paper reports our experience of the perioperative management of patients with sporadic, non-malignant, pancreatic insulinoma. METHODS: A retrospective monocentric cohort study was performed from January 1989 to July 2019, including all the patients who had been operated on for pancreatic insulinoma. The preoperative work-up, surgical management, and postoperative outcome were analyzed. RESULTS: Eighty patients underwent surgery for sporadic pancreatic insulinoma, 50 of which were female (62%), with a median age of 50 (36-70) years. Preoperatively, the tumors were localized in 76 patients (95%). Computed tomography (CT) and magnetic resonance imaging allowed exact preoperative tumor localization in 76% of the patients (64-85 and 58-88 patients, respectively), increasing to 96% when endoscopic ultrasonography was performed. Forty-one parenchyma-sparing pancreatectomies (PSP) (including enucleation, caudal pancreatectomy, and uncinate process resection) and 39 pancreatic resections were performed. The mortality rate was 6% (n = 5), with a morbidity rate of 72%, including 24 severe complications (30%) and 35 pancreatic fistulas (44%). No differences were found between formal pancreatectomy and PSP in terms of postoperative outcome procedures. The surgery was curative in all the patients. CONCLUSION: CT used in combination with endoscopic ultrasonography allows accurate localization of insulinomas in almost all patients. When possible, a parenchyma-sparing pancreatectomy should be proposed as the first-line surgical strategy.

OBJECTIVES: Adenocarcinomas of the esophagus and of the gastric cardia are regarded as a same clinical entity in oncology. For endoscopic resection however, endoscopic mucosal resection is recommended for esophageal adenocarcinoma, while endoscopic submucosal dissection (ESD) is advocated for gastric adenocarcinomas. Our aim was to compare the outcomes of ESD in both types of esophagogastric junction adenocarcinomas. METHODS: Between March 2015 and December 2019, we included all patients who underwent an ESD for early adenocarcinoma of the esophagogastric junction at a French tertiary referral center. Esophageal and gastric cardia adenocarcinomas were compared in terms of clinical, procedural and histological outcomes. RESULTS: 57 esophageal and 19 gastric cardia adenocarcinomas were included in the analysis, for a total of 76 patients. The median (IQR) size of the resections was 40 (40-57.5) and 50 (35-55)mm, p=0.96, respectively. En bloc resection was achieved in 100% and 89% for adenocarcinomas of the esophagus and the gastric cardia, p=0.06. Late adverse events occurred in 14% and 5.3%, respectively, p=0.44, with no severe adverse event. Curative resection rates were 67% and 63% for adenocarcinomas of the esophagus and the gastric cardia, respectively, p=0.89. CONCLUSION: ESD is a safe treatment for T1 adenocarcinomas of the esophagogastric junction, curative in two thirds of the patients, in tumors arising from the esophagus or from the stomach. ESD should be considered for the routine resection of esophageal adenocarcinomas.

Parenchymal sparing duodenal and pancreatic resection are safe procedures in selected patients with the aim to reduce endocrine and exocrine long-term dysfunction. When the tumor is benign or borderline malignant, this appears to be a good option for the surgeon, associated with low rates of severe surgery-related early postoperative complications and low in-hospital mortality. This mini review offers comments, tips and tricks, and a review of literature concerning those different options with specific illustrations in order to clarify their indication.
