RESUMO
BACKGROUND AND AIMS: Gastric emptying scintigraphy (GES) is the criterion standard for the diagnosis of gastroparesis. However, data are lacking regarding the prognostic value of preoperative intragastric meal distribution during GES in patients undergoing gastric peroral endoscopic myotomy (G-POEM) for gastroparesis. This study investigated the association of GES morphologic parameters and the long-term clinical success of G-POEM. METHODS: This retrospective study included patients who underwent G-POEM for refractory gastroparesis in a tertiary center with preoperative GES data. Intragastric meal distribution was measured using the proximal to distal count ratio (PDCR) at 0, 1, 2 and 4 hours, and the retention index was calculated. Clinical success was defined as a decrease of at least 50% in the Gastroparesis Cardinal Symptom Index total score after G-POEM. RESULTS: In total, 77 patients were included with a mean follow-up of 40.14 months. Clinical success was observed in 54.55% of patients. The retention index was not associated with clinical success. Only PDCR at 0 hours (PDCR0) was associated with clinical success. In univariate analysis, the median PDCR0 was 6.0 (interquartile range, 5.59) in patients with clinical success and 4.29 (interquartile range, 4.51) in patients with clinical failure (P = .019). In multivariate analysis, PDCR0 >5.25 was associated with clinical success (odds ratio, 4.36; 95% confidence interval, 1.55-12.26; P = .00524). CONCLUSIONS: This study suggests that in patients with gastroparesis, a high PDCR0 value (suggestive for a preferential fundic meal distribution) during preoperative GES is associated with long-term clinical response to G-POEM.
RESUMO
BACKGROUND: Complete digestive disunion due to anastomotic necrosis is considered a contraindication to endoscopic repair. However, recent publications have suggested that endoscopic treatment by insertion of a self-expandable metal stent (SEMS) is possible. The report of this patient series aims to demonstrate the use of endoscopic management in selected cases with complete digestive disunion. METHODS: Seven consecutive patients with complete and circumferential upper gastrointestinal anastomotic disunion were treated at two European tertiary care centers between 2009 and 2021 by endoscopic insertion of an SEMS. Treatment was performed with a therapeutic gastroscope under general anesthesia, carbon dioxide insufflation, and fluoroscopic guidance, after surgical or percutaneous drainage. RESULTS: All patients were successfully treated by endoscopic insertion of fully or partially covered SEMS left in place for a median of 8 weeks, with a median of 3 endoscopic sessions. Digestive neo-epithelialization was associated with a restored circumferential gut lumen in all cases. The rate of stent migration was 23% and three patients (43%) experienced symptomatic strictures, which were successfully treated by endoscopic dilation. CONCLUSION: Complete digestive rupture could be successfully treated by endoscopy in selected cases, adding proof-of-concept data regarding guided tissue regeneration alongside SEMS placement.

INTRODUCTION: Gastric peroral endoscopic myotomy (G-POEM) is a promising technique for treating refractory gastroparesis. We present the first double-blind randomized study comparing the clinical efficacy of G-POEM versus pyloric botulinum toxin injection (BTI). METHODS: This randomized study, conducted in two expert centers, enrolled patients with refractory gastroparesis, medically managed for >6 months and confirmed by gastric emptying scintigraphy (GES), into two groups, G-POEM versus BTI, with follow-up of 1 year. The primary end point was the 3-month clinical efficacy, defined as a >1-point decrease in the mean Gastroparesis Cardinal Symptom Index (GCSI) score. Secondary end points were: 1-year efficacy, GES evolution, adverse events, and quality of life. RESULTS: 40 patients (22 women; mean age 48.1 [SD 17.4]), with mean symptom duration of 5.8 (SD 5.7) years, were randomized. Etiologies included idiopathic (n=18), diabetes (n=11), postoperative (n=6), and mixed (n=4). G-POEM showed a higher 3-month clinical success than BTI (65% vs. 40%, respectively; P=0.10), along with non-significantly higher 1-year clinical success (60% vs. 40%, respectively) on intention-to-treat analysis. The GCSI decreased in both groups at 3 months and 1 year. Only three minor adverse events occurred in the G-POEM group. The GES improvement rate was 72% in the G-POEM group versus 50% in the BTI group (non-significant). CONCLUSION: G-POEM seems to have a higher clinically relevant success rate than BTI, but this was not statistically demonstrated. This study confirms the interest in treatments targeting the pylorus, either mechanically or chemically, for managing refractory gastroparesis.

BACKGROUND/AIMS: The evaluation of visceral hypersensitivity and gastric accommodation in patients with gastroparesis (GP) is difficult. CT-scan gastric volumetry allows to test the distension of different regions of the stomach. We aimed to study gastric volumes and patient's sensitivity to gastric distension between in patients with GP compared to patients with GERD. METHOD: Retrospective study including patients who had CT-scan volumetry for GP or GERD. Two CT-scan series were made after gastric distension: left lateral decubitus 30° (LLD30) for antrum and right lateral decubitus (RLD) for body. Pain and discomfort were assessed using visual analogue scale (VAS). Gastric volumes were measured for LLD30 and RLD. RESULTS: 13 patients (7 GP and 6 GERD) were included. Mean age was 35.6+/-7.3 years. Median gastric volume in the RLD was lower in GP vs GERD (927+/-208 ml vs. 1115+/-163 ml; p = 0.046) while it was similar for LLD30 (1053+/-228 ml vs. 1054+/-193 ml; p = 0.603). GP patients had significantly more pain and discomfort during the procedure: pain VAS for GP was 6[0-9] versus 0[0-2] for GERD, p = 0.004, discomfort VAS for GP was 7[4-10] versus 4[0-5] for GERD, p = 0.007. 66.7% of GERD patients felt no pain vs. 14.3% in GP, p = 0.053. CONCLUSION: This pilot study suggests that GP could be associated with a reduced gastric volume compared to GERD in RLD after gaseous distension. In contrast, patient self-assessment of pain related to gastric distension was greater int GP patients. A lack of fundus accommodation and visceral hypersensitivity could explain some mechanisms in the genesis of GP symptoms.
Gastroparesis is associated with lower volumes in right lateral decubitus suggesting a lower distensibility of the fundus.Gastric volumetry is more painful in patients with gastroparesis than GERD controls, suggesting visceral hypersensitivity to mechanical distension.

INTRODUCTION: The prevalence of esophageal motor disorders (EMD) in PPI-refractory gastroesophageal reflux disease (GERD) is substantial. However, limited data exist on their impact on the efficacy of endoscopic treatments like anti-reflux mucosectomy (ARMS). This study aimed to evaluate the influence of EMD on ARMS efficacy in patients with PPI-refractory GERD. METHOD: This single-center retrospective study enrolled patients with refractory GERD treated with ARMS-b (anti-reflux mucosectomy band-ligation). High-resolution esophageal manometry (HREM) was conducted before the procedure to identify EMD presence. The primary endpoint was treatment efficacy, defined as >50% improvement in GERD-HRQL score at 1 year. Secondary endpoints included PPI intake, symptom control, ARMS complications, and overall patient satisfaction at 12 months. RESULTS: The study included 65 patients, with 41 (63.1%) showing EMD on HREM. Treatment efficacy was achieved by 33.8% (22) of patients, with 8 without EMD, 11 having isolated LES hypotonia, and 3 with both LES hypotonia and esophageal body motor disorder. No significant differences were observed between patients with and without EMD regarding the primary endpoint, PPI use, symptom control, or complications. Dysphagia developed in 52.3% (34) within 6 months, leading to esophageal dilatation in 15.3% (10). Two patients experienced acute hemorrhage, and one had perforation. CONCLUSION: The presence of esophageal motor disorders does not seem to impact ARMS response, suggesting the technique's consideration in this population. Larger studies are essential for confirming these results and exploring treatment response and post-operative predictors.

PURPOSE: Gastric outlet obstruction (GOO) is mainly due to advanced malignant disease. GOO can be treated by surgical gastroenterostomy (SGE), endoscopic enteral stenting (EES), or endoscopic ultrasound-guided gastroenterostomy (EUS-GE) to improve the quality of life. METHODS: Between 2009 and 2022, patients undergoing SGE or EUS-GE for GOO were included at three centers. Technical and clinical success rates, post-procedure adverse events (AEs), length of hospital stay (LOS), 30-day all-cause mortality, and recurrence of GOO were retrospectively analyzed and compared between SGE and EUS-GE. Predictive factors for technical and clinical failure after SGE and EUS-GE were identified. RESULTS: Of the 97 patients included, 56 (57.7%) had an EUS-GE and 41 (42.3%) had an SGE for GOO, with 62 (63.9%) GOO due to malignancy and 35 (36.1%) to benign disease. The median follow-up time was 13,4 months (range 1 days-106 months), with no difference between the two groups (p = 0.962). Technical (p = 0.133) and clinical (p = 0.229) success rates, severe morbidity (p = 0.708), 30-day all-cause mortality (p = 0.277) and GOO recurrence (p = 1) were similar. EUS-GE had shorter median procedure duration (p < 0.001), lower post-procedure ileus rate (p < 0.001), and shorter median LOS (p < 0.001) than SGE. In univariate analysis, no risk factors for technical or clinical failure in SGE were identified and abdominal pain reported before the procedure was a risk factor for technical failure in the EUS-GE group. No risk factor for clinical failure was identified for EUS-GE. In the subgroup of GOO due to benign disease, SGE was associated with better technical success (p = 0.035) with no difference in clinical success rate compared to EUS-GE (p = 1). CONCLUSION: EUS-GE provides similar long-lasting symptom relief as SGE for GOO whether for benign or malignant disease. SGE may still be indicated in centers with limited experience with EUS-GE or may be reserved for patients in whom endoscopic technique fails.

BACKGROUND AND AIMS: The use of laparoscopic fundoplication (LF) to treat refractory GERD may induce refractory dysphagia (5%-10%). The management is complex, and peroral endoscopic myotomy (POEM) including valve incision is a new therapeutic option. METHODS: This retrospective study involved patients with postfundoplication refractory dysphagia treated by POEM associated with complete wrap incision. Patients were evaluated with Eckardt and dysphagia scores. Study objectives were to evaluate clinical and technical outcomes, adverse events, and GERD recurrence. RESULTS: Twenty-six patients, with a mean age of 57.3 ± 15.6 years, were included. Mean follow-up was 25.3 ± 17.6 months. The technical and clinical success rates were 96% and 84.6%, respectively. Among failures, 1 patient underwent Lewis-Santy, 2 required dilations, and 1 was lost to follow-up. Three late recurrences occurred and were endoscopically managed. Five patients (19%) had GERD recurrence that was mainly improved by proton pump inhibitors. CONCLUSIONS: POEM with fundoplication is a serious therapeutic option for managing persistent dysphagia after LF, with a low risk of GERD recurrence.
RESUMO
BACKGROUND AND AIMS: EUS-guided radiofrequency ablation (EUS-RFA) has been described as a potentially curative option for solid and cystic pancreatic neoplasms. We aimed to assess the safety and efficacy of pancreatic EUS-RFA in a large study population. METHODS: A retrospective study retrieving all consecutive patients who underwent pancreatic EUS-RFA during 2019 and 2020 in France was conducted. Indication, procedural characteristics, early and late adverse events (AEs), and clinical outcomes were recorded. Risk factors for AEs and factors related to complete tumor ablation were assessed on univariate and multivariate analyses. RESULTS: One hundred patients (54% men, 64.8 ± 17.6 years old) affected by 104 neoplasms were included. Sixty-four neoplasms were neuroendocrine neoplasms (NENs), 23 were metastases, and 10 were intraductal papillary mucinous neoplasms with mural nodules. No procedure-related mortality was observed, and 22 AEs were reported. Proximity of pancreatic neoplasms (≤1 mm) to the main pancreatic duct was the only independent risk factor for AEs (odds ratio [OR), 4.10; 95% confidence interval [CI), 1.02-15.22; P = .04). Fifty-nine patients (60.2%) achieved a complete tumor response, 31 (31.6%) a partial response, and 9 (9.2%) achieved no response. On multivariate analysis, NENs (OR, 7.95; 95% CI, 1.66-51.79; P < .001) and neoplasm size <20 mm (OR, 5.26; 95% CI, 2.17-14.29; P < .001) were independently related to complete tumor ablation. CONCLUSIONS: The results of this large study confirm an overall acceptable safety profile for pancreatic EUS-RFA. Close proximity (≤1 mm) to the main pancreatic duct represents an independent risk factor for AEs. Good clinical outcomes in terms of tumor ablation were observed, especially for small NENs.

BACKGROUND: Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using lumen-apposing metal stents (LAMSs) appears to be effective and safe in gastric outlet obstruction (GOO); however, the EUS-GE procedure is not standardized, with the use of assisted or direct methods still debated. The aim of this study was to compare the outcomes of EUS-GE techniques focusing on an assisted with orointestinal drain wireless endoscopic simplified technique (WEST) and the nonassisted direct technique over a guidewire (DTOG). METHOD: This was a multicenter European retrospective study involving four tertiary centers. Consecutive patients who underwent EUS-GE for GOO between August 2017 and May 2022 were included. The primary aim was to compare the technical success and adverse event (AE) rates of the different EUS-GE techniques. Clinical success was also analyzed. RESULTS: 71 patients (mean [SD] age 66.2 10 years; 42.3â% men; 80.3â% malignant etiology) were included. Technical success was higher in the WEST group (95.1â% vs. 73.3â%; estimate of relative risk from odds ratio (eRR) 3.2, 95â%CI 0.94-10.9; Pâ=â0.01). The rate of AEs was lower in the WEST group (14.6â% vs. 46.7â%; eRR 2.3, 95â%CI 1.2-4.5; Pâ=â0.007). Clinical success was comparable between the two groups at 1 month (97.5â% vs. 89.3â%). The median follow-up was 5 months (range 1-57). CONCLUSION: The WEST resulted in a higher technical success rate with fewer AEs, with clinical success comparable with the DTOG. Therefore, the WEST (with an orointestinal drain) should be preferred when performing EUS-GE.

BACKGROUND: Peroral endoscopic myotomy (POEM) is a very effective treatment for achalasia. However, training remains non-standardized. We evaluated a training curriculum, including ex vivo cases, followed by patients' cases under expert supervision. The objective was to establish a learning curve of POEM. MATERIALS AND METHODS: Four operators having completed advanced endoscopy fellowship were involved. They had already observed > 30 cases performed by experts. They performed 30 POEMs standardized (tunnel and myotomy lengths) procedures on ex vivo porcine model. Procedural times, number/volume of injections, mucosal and serous perforations, and myotomy length were collected. The learning curve was assessed using dissection speed (DS) and a dedicated performance score (PS), including learning rate (LR) and learning plateau (LP). RESULTS: The operators completed all cases within 4 months (median of 3.5 cases/week). The mean procedural time was 43.3 min ± 14.4. Mean myotomy length was 70.0 mm ± 15.6 mm. Dissection speed averaged 1.78 mm/min ± 0.78. Using DS and PS as parameter, the LR was reached after 12.2 cases (DS = 2.0 mm/min) and 10.4 cases, respectively. When comparing the LP and the plateau phase, the DS was slower (1.3 ± 0.5 mm/min versus 2.1 ± 0.54 mm/min, p < 0.005) and perforations were decreased: 0.35 ± 0.82 in LP vs. 0.16 ± 0.44 in PP. Following this training, all operators performed 10 supervised cases and are competent in POEM. CONCLUSION: The association of observed cases and supervised ex vivo model training is effective for starting POEM on patients. The learning curve is 12 cases to reach a plateau.

BACKGROUND AND AIMS: Limited data exist concerning the long-term efficiency of gastric peroral endoscopic myotomy (G-POEM) as a treatment of refractory gastroparesis. This study evaluated the 3-year results of G-POEM in patients with refractory gastroparesis. METHODS: This was a prospective multicenter study of all G-POEM operations performed in 2 expert French centers for 46 patients with refractory gastroparesis with at least 3 years of follow-up. RESULTS: Clinical success was 65.2% at 36 months. There was significant improvement in symptom severity. Median Gastroparesis Cardinal Symptom Index decreased from 3.33 to 1.80 (P < .0001), with improvement in all subscales. We created a predictive score concerning G-POEM success (G-POEM predictive score) to which points were assigned as follows: nausea subscale <2: predictive of success, 1 point; satiety subscale >4: predictive of success, 1 point; bloating subscale >3.5: predictive of success, 1 point; percentage of gastric retention at 4 hours on scintigraphy >50%: 1 point. A threshold of 2 was identified by receiver operating characteristic curve analysis with an area under the curve of .825 that predicted clinical success with a sensitivity of 93.3% (95% confidence interval [CI], .77-.99), specificity of 56.3% (95% CI, .33-.77), positive predictive value of 80% (95% CI, .67-.93), negative predictive value of 81.8% (95% CI, .59-1.00), and accuracy of 80.4% (95% CI, .69-.92). Patients with a score ≥2 were significantly more likely to be responders at 3 years than were patients with a score <2 (80% and 18%, respectively; P = .0004). CONCLUSIONS: The clinical success of G-POEM for refractory gastroparesis was 65.2% at 36 months. Our predictive score offers an easy tool that needs to be confirmed in other studies.

BACKGROUND: Endoscopic internal drainage (EID) with double-pigtail stents or low negative-pressure endoscopic vacuum therapy (EVT) are treatment options for leakage after upper gastrointestinal oncologic surgery. We aimed to compare the effectiveness of these techniques. METHODS: Between 2016 and 2019, patients treated with EID in five centers in France and with EVT in Göttingen, Germany were included and retrospectively analyzed using univariate analysis. Pigtail stents were changed every 4 weeks; EVT was repeated every 3-4 days until leak closure. RESULTS: 35 EID and 27 EVT patients were included, with a median (interquartile range [IQR]) leak size of 0.75âcm (0.5-1.5). Overall treatment success was 100â% (95â% confidence interval [CI] 90â%-100â%) for EID vs. 85.2â% (95â%CI 66.3â%-95.8â%) for EVT (Pâ=â0.03). The median (IQR) number of endoscopic procedures was 2 (2-3) vs. 3 (2-6.5; Pâ=â0.003) and the median (IQR) treatment duration was 42 days (28-60) vs. 17 days (7.5-28; Pâ<â0.001), for EID vs. EVT, respectively. CONCLUSION: EID and EVT provide high closure rates for upper gastrointestinal anastomotic leaks. EVT provides a shorter treatment duration, at the cost of a higher number of procedures.

BACKGROUND: Pelvic collections may occur after surgery or in medical diseases. EUS transmural (TM) treatment has been shown as highly effective and safe, becoming an alternative to surgery or radiology. We aimed to assess the results of EUS management of pelvic collections. METHODS: Retrospective, single-center observational study conducted between 2004 and 2018. Patients with symptomatic collections treated by EUS-TM approach were enrolled. The procedures were performed with a therapeutic EUS-scope, following two possible options: puncture-aspiration-injection of antibiotics PAIA (group 1) or EUS-drainage by plastic double pigtail stents (DPS) with an ano-cavitary drain (ACD) or lumen-apposing metal Stent (LAMS) (group 2). The main objective was to assess the clinical effectiveness based on symptoms and collection resolution. RESULTS: Seventy-three patients were included. Mean age was 42.5 years [12-87]. 30 patients in group 1 (41%) underwent PAIA and 43 in group 2 (59%) underwent DPS ± ACD in 41 patients (95%) and LAMS in 2. The collection was postoperative in 58%. The mean size was 48.9 mm [8-120], 33 +/- 17 mm in group 1, compared to 67 ± 21 mm in group 2 (p < .0001). All the procedures were technically successful. Overall clinical success was 96% (93% in group 1 (28/30), 98% (42/43) in group 2). Failures occurred in 2 post sigmoiditis abscesses and 1 ileo-colic Crohn's disease. No adverse event was reported. During the median follow-up of 7.5 years [4.4-8.9], no patient had recurrence. CONCLUSIONS: EUS-TM with either PAIA or drainage depending on the collection size is confirmed to be highly effective and safe.

BACKGROUND AND AIMS: No recommendation regarding antibiotic prophylaxis and preparation modalities are available for patients with esophageal motor disorders who benefit from Per-Oral Endoscopic Myotomy (POEM). The aim of our study was to evaluate their impact on the POEM's safety. PATIENTS AND METHODS: This study was a comparative and multicentric retrospective analysis of a database prospectively collected. Patients over 18 years old with esophageal motor disorders confirmed by prior manometry, who underwent POEM were included. The primary endpoint was the occurrence of adverse events, as classified by Cotton, based on whether or not antibiotic prophylaxis was administered. RESULTS: A total of 226 patients (median age 52.9 ± 19.12 years [18-105], 116 women [51.3%]) were included. The indication for POEM was mainly type 2 achalasia (n = 135, 60.3%). Antibiotic prophylaxis was administered to 170 patients (75.2%) during 3.93 ± 3.46 days [1-21]. The overall adverse events rate was 9.3% (n = 21). Antibiotic prophylaxis was associated with the occurrence of adverse events (p = .003), but had no impact on their severity (p = .238). Antibiotic prophylaxis didn't influence the effectiveness of POEM (1 [0-4] vs 1 [0-9], p = .231). The use of a liquid diet in the 48 h prior to the procedure was significantly associated with a lower adverse events rate (3.1% vs 6.19%, p = .0002). CONCLUSION: The antibiotic prophylaxis during POEM does not prevent adverse events, had no impact on their severity and the efficacy of the procedure. A liquid diet before the procedure should be systematically proposed.

INTRODUCTION: In patients with benign and refractory esophageal strictures (BES), repeating initial dilations in short intervals could be recommended, but little data are available to validate this strategy. Our aim was to evaluate long-term results of a scheduled program of repeated and sustained esophageal dilations in patients with refractory strictures. METHODS: Patients with BES requiring five or more dilations were retrospectively included and divided in two groups for analysis: a SCHEDULED group (SDG) where patients were systematically rescheduled for the 5 first dilations; ON-DEMAND group (ODG) where patients were dilated only in case of recurrence of the dysphagia. Comparison between SDG and ODG was done with a 1:1 matching analysis and etiology of stricture. Clinical success was defined as the absence of dysphagia for more than a year. RESULTS: 39 patients with refractory BES were included with post-operative stenosis in 51.2% and post-caustic injury 28.2%; 10 were in SDG and 29 in ODG. In overall analysis (39 patients), the follow-up was 64.4 ± 32 months, success rate was 79.5% and duration of treatment was 27.3 ± 20 months, and mean number of dilations was 11.7 per patient. The need for dilations decreased significantly after 18 months of treatment with an average of 0.56 dilations per semester. Self-expandable metallic stent insertion was associated with an increased rate of complications (5.9% vs 59.1% p = 0.001). In matched analysis (10 ODG vs 10 SDG patients), the duration of treatment was lower in SDG (18.8 vs 41.4 months, p = 0,032) with a higher probability of remission (survival analysis, Log-rank: p = 0,019) and the success rate did not differ between ODG and SDG patients (80% vs 90%; NS). CONCLUSION: Overall, long-term esophageal dilations resulted in a 79.5% success rate and the need for further dilatations decreased significantly in both groups after 18-month follow-up. A scheduled dilation program was associated with a higher probability of final success and lower treatment duration.

OBJECTIVES: A single-use duodenoscope (SUD) has been recently developed to overcome issues with endoscopic retrograde cholangiopancreatography (ERCP)-related cross-infections. The aim was to evaluate SUD safety and performance in a prospective multi-centre study. METHODS: All consecutive patients undergoing ERCP in six French centers were prospectively enrolled. All procedures were performed with the SUD; in case of ERCP failure, operators switched to a reusable duodenoscope. Study outcomes were the successful completion of the procedure with SUD, safety and operators' satisfaction based on a VAS 0-10 and on 22 qualitative items. The study protocol was approved by French authorities and registered (ID-RCB: 2020-A00346-33). External companies collected the database and performed statistical analysis. RESULTS: Sixty patients (34 females, median age 65.5 years old) were enrolled. Main indications were bile duct stones (41.7%) and malignant biliary obstruction (26.7%). Most ERCP were considered ASGE grade 2 (58.3%) or 3 (35.0%). Fifty-seven (95.0%) procedures were completed using the SUD. Failures were unrelated to SUD (one duodenal stricture, one ampullary infiltration, and one tight biliary stricture) and could not be completed with reusable duodenoscopes. Median operators' satisfaction was 9 (7-9). Qualitative assessments were considered clinically satisfactory in a median of 100% of items and comparable to a reusable duodenoscope in 97.9% of items. Three patients (5%) reported an adverse event. None was SUD-related. CONCLUSIONS: The use of a SUD allows ERCP to be performed with an optimal successful rate. Our data show that SUD could be used for several ERCP indications and levels of complexity.

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.

BACKGROUND: Data on the long-term outcomes of gastric peroral endoscopic myotomy (G-POEM) for refractory gastroparesis are lacking. We report the results of a large multicenter long-term follow-up study of G-POEM for refractory gastroparesis. METHODS: This was a retrospective multicenter study of all G-POEM operations performed in seven expert French centers for refractory gastroparesis with at least 1 year of follow-up.âThe primary endpoint was the 1-year clinical success rate, defined as at least a 1-point improvement in the Gastroparesis Cardinal Symptom Index (GCSI). RESULTS: 76 patients were included (60.5â% women; age 56 years). The median symptom duration was 48 months. The median gastric retention at 4 hours (H4) before G-POEM was 45â% (interquartile range [IQR] 29â%â-â67â%). The median GCSI before G-POEM was 3.6 (IQR 2.8â-â4.0). Clinical success was achieved in 65.8â% of the patients at 1 year, with a median rate of reduction in the GCSI score of 41â%. In logistic regression analysis, only a high preoperative GCSI satiety subscale score was predictive of clinical success (odds ratio [OR] 3.41, 95â% confidence interval [CI] 1.01â-â11.54; Pâ=â0.048), while a high rate of gastric retention at H4 was significantly associated with clinical failure (OR 0.97, 95â%CI 0.95â-â1.00; Pâ=â0.03). CONCLUSIONS: The results confirm the efficacy of G-POEM for the treatment of refractory gastroparesis, as evidenced by a 65.8â% clinical success rate at 1 year. Although G-POEM is promising, prospective sham-controlled trials are urgently needed to confirm its efficacy and identify the patient populations who will benefit most from this procedure.

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.

BACKGROUND: After lung transplantation (LT), gastroparesis is frequent, occurring in 25-63% of cases and leading to pulmonary infections. In refractory disease, classical management has demonstrated limited efficacy. Gastric peroral endoscopic myotomy (G-POEM) is a recently developed safe and effective procedure that has been performed here on five patients with severe post-LT gastroparesis. METHODS: In all patients, the diagnosis was confirmed by disturbed gastric emptying scintigraphy and GCSI calculation showing severe disease. Upper gastrointestinal endoscopies confirmed the absence of organic lesions. All patients were informed about the procedure and signed informed consent forms. The procedure consisted of performing an endoscopic pyloromyotomy under general anesthesia. RESULTS: The patients were between 35 and 64 years of age. Four had chronic disease, starting approximately 1 year following LT, and one had acute, severe gastroparesis requiring intubation in the intensive care unit. All patients underwent G-POEM after failure of medical treatment, without any complications. Three of the patients with chronic disease improved; they resumed a normal diet and gained weight. The patient with acute disease was discharged within a few days following the procedure and resumed oral intake. CONCLUSION: G-POEM is promising for managing post-LT refractory gastroparesis and should be further evaluated.
