North American Expert Consensus on the Post-procedural Care of Patients After Per-oral Endoscopic Myotomy Using a Delphi Process. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00792-4. [PMID: 39214390 DOI: 10.1016/j.cgh.2024.08.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2024] [Revised: 08/02/2024] [Accepted: 08/18/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND & AIMS There is significant variability in the immediate post-operative and long-term management of patients undergoing per-oral endoscopic myotomy (POEM), largely stemming from the lack of high-quality evidence. We aimed to establish a consensus on several important questions on the after care of post-POEM patients through a modified Delphi process. METHODS A steering committee developed an initial questionnaire consisting of 5 domains (33 statements): post-POEM admission/discharge, indication for immediate post-POEM esophagram, peri-procedural medications and diet resumption, clinic follow-up recommendations, and post-POEM reflux surveillance and management. A total of 34 experts participated in the 2 rounds of the Delphi process, with quantitative and qualitative data analyzed for each round to achieve consensus. RESULTS A total of 23 statements achieved a high degree of consensus. Overall, the expert panel agreed on the following: (1) same-day discharge after POEM can be considered in select patients; (2) a single dose of prophylactic antibiotics may be as effective as a short course; (3) a modified diet can be advanced as tolerated; and (4) all patients should be followed in clinic and undergo objective testing for surveillance and management of reflux. Consensus could not be achieved on the indication of post-POEM esophagram to evaluate for leak. CONCLUSIONS The results of this Delphi process established expert agreement on several important issues and provides practical guidance on key aspects in the care of patients following POEM.

Abstract
Background and Aims Fluoroscopy-free endoscopic retrograde cholangiopancreatography for common bile duct stone (CBDS) clearance is usually offered only to pregnant patients. We initiated a multicenter, randomized controlled trial comparing clearance of non-complex CBDSs using fluoroscopy-free direct solitary cholangioscopy (DSC) to standard endoscopic retrograde cholangiography (ERC) to evaluate the wider applicability of the DSC-based approach. Here we report the initial results of stone clearance and safety in roll-in cases for the randomized controlled trial. Methods Twelve expert endoscopists at tertiary care centers in four countries prospectively enrolled 47 patients with non-complex CBDSs for DSC-assisted CBDS removal in an index procedure including fluoroscopy-free cannulation. Successful CBDS clearance was first determined by DSC and subsequently validated by final occlusion cholangiogram as the ERC gold standard. Results Fully fluoroscopy-free cannulation was successful in 42/47 (89.4%) patients. Brief fluoroscopy with minimal contrast injection was used in 4/47 (8.5%) patients during cannulation. Cannulation failed in 1/47 (2.1%) patients. Fluoroscopy-free complete stone clearance was reached in 38/46 (82.6%) cases. Residual stones were detected in the validation ERC occlusion cholangiogram in three cases. Overall serious adverse event rate was 2.1% (95% confidence interval 0.1-11.3): postprocedural pancreatitis in one patient. Conclusions In patients with non-complex CBDS, the fluoroscopy-free technique is easily transferred to endoscopic retrograde cholangiopancreatography experts with acceptable rates of cannulation and stone clearance and few serious adverse events.

Abstract
BACKGROUND Endoscopic papillectomy (EP) offers a safe and effective method for resection of ampullary adenomas. Data regarding the long-term resolution of adenoma following EP are limited. The aim of this study therefore was to examine the timing of recurrence after EP of ampullary adenomas. METHODS This was a single-center retrospective study including patients who received EP for ampullary adenomas from 8/2000 to 1/2018. Patients with confirmed complete eradication of adenoma were included in the recurrence analysis with recurrence defined as finding adenomatous histology after 1 negative surveillance endoscopy. Kaplan-Meier estimates were calculated to determine recurrence rates. RESULTS Of the 165 patients who underwent EP, 136 patients (mean age 61.9, 51.5% female) had adenomatous histology with a mean lesion size of 21.2 mm. A total of 124 (91.2%) achieved complete eradication with a follow-up of 345.8 person-years. Recurrence occurred in 20 (16.1%) patients at a mean of 3.2 (± 3) years (range 0.5-9.75 years) for a recurrence rate of 5.8 (95% CI 3.6-8.8) per 100 person-years. Nine (45%) recurrences occurred after the 1st 2 years of surveillance. Recurrence rate did not differ by baseline pathology [low-grade dysplasia: 5.2 (95% CI 3.0-9.0), high-grade dysplasia: 6.9 (95% CI 2.3-15.5), adenocarcinoma: 7.7 (95% CI 0.9-25.1)]. CONCLUSION Recurrence remains a significant concern after EP. Given the timing of recurrence, long surveillance periods may be necessary. Larger multicenter studies are needed, however, to determine appropriate surveillance intervals.

Direct cost variance analysis of peroral endoscopic myotomy vs heller myotomy for management of achalasia: A tertiary referral center experience. World J Gastrointest Endosc 2023; 15:593-601. [PMID: 37900115 PMCID: PMC10600690 DOI: 10.4253/wjge.v15.i10.593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 08/23/2023] [Accepted: 09/11/2023] [Indexed: 10/12/2023] Open
Abstract
BACKGROUND Laparoscopic Heller myotomy (LHM) has been the traditional surgical treatment for achalasia. Recently, peroral endoscopic myotomy (POEM) has demonstrated similar clinical outcomes with shorter procedure times. Studies comparing the direct cost-effectiveness of POEM vs LHM are limited. AIM To compare costs of POEM vs LHM. METHODS This retrospective chart review aimed to compare the outcomes and cost of clinical care between patients who underwent POEM and LHM procedures for achalasia. The study was conducted at a tertiary academic center from January 2019 to December 2020. Clinical outcomes, including post-operative Eckardt scores and adverse events, were assessed and compared between the two groups. Direct cost variance analysis was utilized to evaluate the cost of clinical care incurred by patients undergoing POEM in the year preceding the procedure, during the index admission, and one year post-procedure, in comparison to patients undergoing LHM. RESULTS Of 30 patients were included (15 POEM and 15 LHM) in the study. Patients in the POEM group had a mean Eckardt score of 0.5 ± 0.5 post-procedure, which was no different from patients in the LHM group (0.7 ± 0.6, P = 0.17) indicating comparative efficacy. However, the total costs of the admission for the procedure in the LHM group were on average $1827 more expensive than in the POEM group (P < 0.01). Total healthcare costs one year prior to index procedure were $7777 higher in the LHM group, but not statistically different (P = 0.34). The patients in the LHM group one year after the index procedure had accrued $19730.24 larger total cost, although this was not statistically different from POEM group (P = 0.68). CONCLUSION Despite similar clinical outcomes, the cost of the index procedure admission for POEM was significantly lower than for LHM. The difference was primarily related to shorter time increments utilized in the operating room during the index procedure, and shorter length of hospital stay following POEM.

Surg Endosc 2023; 37:7767-7773. [PMID: 37580583 PMCID: PMC10771858 DOI: 10.1007/s00464-023-10319-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Accepted: 07/19/2023] [Indexed: 08/16/2023]
Abstract
BACKGROUND The Eckardt score (ES) is used to assess symptom response to Per-Oral Endoscopic Myotomy (POEM), but reliable methods to assess physiologic success are needed. Functional lumen imaging probe (FLIP) panometry has a potential role in post-POEM follow-up to predict long-term outcomes. The aim of this study was to assess the correlation between clinical success and FLIP parameters following POEM to determine if short interval FLIP could predict long-term outcomes. METHODS This was a prospective study of adult patients who underwent POEM with short interval follow-up FLIP between 11/2017 and 3/2020. Clinical success was defined as post-procedure ES ≤ 3. Physiologic success was based on an esophago-gastric junction distensibility index (EGJ-DI) > 2.8 mm2/mmHg on FLIP. RESULTS 47 patients (55% female, mean age 55 years) were included in the study. Clinical success after POEM was seen in 45 (96%) patients (mean ES 6.5 ± 2.2 pre and 0.83 ± 1.0 post-POEM, p < 0.001). Physiologic success was noted in 43 (91.5%) patients (mean EGJ-DI 6.1 mm2/mmHg ± 2.5). Among 4 patients not meeting criteria for physiologic success, EGJ-DI was 2.5-2.6. There was no correlation between post-POEM EGJ-DI and ES in the short term or long term. Significant reflux esophagitis was seen in 6 (12.8%) patients with no difference in mean EGJ-DI with vs without esophagitis (5.9 vs 6.1, p = 0.44). CONCLUSION Post-POEM endoscopy with FLIP is useful to both assess EGJ physiology and to examine for reflux esophagitis. Short interval FLIP has limited utility to predict long-term patient outcomes or risk of acid reflux.

Abstract
BACKGROUND Flexible endoscopic therapy of Zenker's diverticulum using submucosal tunneling (Z-POEM) similar to esophageal Per-Oral Endoscopic Myotomy (POEM) is becoming increasingly common. However, data comparing Z-POEM with traditional flexible endoscopic septotomy (FES) are sparse. The aim of this study was to compare outcomes of Z-POEM with traditional FES over a medium-term follow-up period. METHODS This was a prospective study of patients who underwent Z-POEM for treatment of Zenker's diverticulum between 2018 and 2020 at a tertiary academic medical center compared to prior patients who had FES (between 2015 and 2018). Procedural characteristics and clinical outcomes (technical and clinical success, and adverse events) were compared between patients who underwent each treatment. RESULTS A total of 28 patients underwent ZD therapy during the study period. 13 patients (mean age 70 years; 77% male) underwent Z-POEM and 15 patients (mean age 72 years; 73% male) underwent traditional FES. The mean Zenker's diverticulum size was 2.4 ± 0.6 cm in the ZPOEM group vs 2.5 ± 0.8 cm in the FES group. The mean procedure time was similar between groups: 43.9 min (range 26-66) in the Z-POEM group and 60.2 min (range 25-92) in the traditional FES group (t = 1.74 p = 0.19). Overall technical success was seen in 100% of patients. There was one adverse event in the FES group (dehydration resulting in near-syncope) (1/28, 3.6%). Overall clinical success was seen in 92.8% (26/28) of patients and was not significantly different between groups (Z-POEM; 13/13, 100% vs FES; 13/15, 86.7%, t = - 1.36 p = 0.18). CONCLUSION This prospective study suggests that ZPOEM is an effective technique for the treatment of Zenker's diverticulum with no significant differences in clinical outcomes or adverse event rates when compared to traditional FES.

Abstract
Endoscopic full-thickness resection (EFTR) has emerged as a viable technique in the management of mucosal and subepithelial lesions of the gastrointestinal tract (GIT) not amenable to conventional therapeutic approaches. While various devices and techniques have been described for EFTR, a single, combined full-thickness resection and closure device (full-thickness resection device, FTRD system, Ovesco Endoscopy AG, Tuebingen, Germany) has become commercially available in recent years. Initially, the FTRD system was limited to use in the colorectum only. Recently, a modified version of the FTRD has been released for EFTR in the upper GIT as well. This review provides a broad summary of the FTRD, highlighting recent advances and current challenges.

Abstract
BACKGROUND AND AIMS The gas-filled intragastric balloon (IGB) system (Obalon) and the fluid-filled IGB system (Orbera) are the current FDA-approved IGB systems to treat obesity; however, they have not been previously compared in clinical practice. The aims of this study were to compare their efficacy, tolerance, and safety in a clinical setting. MATERIALS AND METHODS This is a retrospective cohort study of consecutive patients treated with the gas-filled IGB or fluid-filled IGB between October 2015 and May 2020 at 2 academic centers. The primary endpoints included percent total body weight loss at balloon removal in patients who completed at least 20 weeks of therapy, the difference in adverse events that required urgent evaluation or hospitalization, and early removal in the 2 groups. RESULTS A total of 87 patients underwent successful IGB placement (gas-filled IGB n=57, age 48.9±8.8, body mass index 35.5±5 kg/m 2 ; fluid-filled IGB n=30, age 49.2±14.3, body mass index 38.8±6 kg/m 2 ). Eleven patients underwent early device removal. There were no differences in percent total body weight loss at balloon removal and 12 months between the balloon systems ( P =0.39). Patients who received the fluid-filled IGB were more likely to require urgent evaluation or treatment, require hospital stay >24 hours, and need early balloon system removal compared with patients treated with the gas-filled IGB. CONCLUSION In this 2-center cohort, both FDA-approved gastric balloon systems had the same effectiveness, but the gas-filled IGB had fewer serious adverse events and better tolerability than the fluid-filled IGB.

Abstract
OBJECTIVE We evaluated a protocolized endoscopic necrosectomy approach with a lumen-apposing metal stent (LAMS) in patients with large symptomatic walled-off pancreatic necrosis (WON) comprising significant necrotic content, with or without infection. SUMMARY BACKGROUND DATA Randomized trials have shown similar efficacy of endoscopic treatment compared with surgery for infected WON. DESIGN We conducted a regulatory, prospective, multicenter single-arm clinical trial examining the efficacy and safety of endoscopic ultrasound -guided LAMS with protocolized necrosectomy to treat symptomatic WON ≥6 cm in diameter with >30% solid necrosis. After LAMS placement, protocolized WON assessment was conducted and endoscopic necrosectomy was performed for insufficient WON size reduction and persistent symptoms. Patients with radiographic WON resolution to ≤ 3 cm and/or 60-day LAMS indwell had LAMS removal, then 6-month follow-up. Primary endpoints were probability of radiographic resolution by 60 days and procedure-related serious adverse events. RESULTS Forty consecutive patients were enrolled September 2018 to March 2020, of whom 27 (67.5%) were inpatients and 19 (47.5%) had clinical evidence of infection at their index procedure. Mean WON size was 15.0 ± 5.6 cm with mean 53.2% ± 16.7% solid necrosis. Radiographic WON resolution was seen in 97.5% (95% CI, 86.8%, 99.9%) by 60 days, without recurrence in 34 patients with 6-month follow-up data. Mean time to radiographic WON resolution was 34.1 ± 16.8 days. Serious adverse events occurred in 3 patients (7.5%), including sepsis, vancomycin-resistant enterococcal bacteremia and shock, and upper gastrointestinal bleeding. There were no procedure-related deaths. CONCLUSIONS Endoscopic ultrasound-guided drainage with protocolized endoscopic necrosectomy to treat large symptomatic or infected walled-off necrotic pancreatic collections was highly effective and safe.

Abstract
BACKGROUND AND STUDY AIMS : Peroral endoscopic myotomy (POEM) is a minimally invasive endoscopic procedure for the treatment of achalasia and certain spastic esophageal motility disorders, delivering excellent results in experienced hands. However, this complex and technically challenging procedure requires advanced endoscopic skills. The aim of this study was to conduct a systematic review and meta-analysis of current data to evaluate the learning curve for POEM in new adopters of this technique. METHODS : Electronic databases (PubMed, Embase, and Cochrane Library) from inception to November 2021 were searched for publications addressing the learning curve in POEM. Pooling was conducted by both fixed- and random-effects models. Secondary outcomes reviewed were clinical success defined by Eckardt score ≤ 3 when available and adverse events. RESULTS : Eight studies involving 1904 patients met the inclusion criteria. In the pooled analysis, new adopters of POEM attained proficiency at a mean of 24.67 procedures (95 %CI 23.93 to 25.41). Once proficiency was achieved, the pooled total procedure time plateaued at a mean of 85.38 minutes (95 %CI 81.48 to 89.28), the pooled mean procedure time per centimeter of myotomy was 6.25 minutes (95 %CI 5.69 to 6.82), and the pooled mean length of myotomy was 11.49 cm (95 %CI 10.90 to 12.08). CONCLUSIONS : Our analysis showed that new adopters of POEM with previous advanced endoscopy experience required about 25 procedures to attain proficiency. The average time for each procedure once proficiency was attained was about 85 minutes.

Abstract
BACKGROUND AND AIMS The American Society for Gastrointestinal Endoscopy (ASGE) advanced endoscopy fellowship (AEF) match offers a structured application process for AEF training in the United States. Our aim was to describe recent trends in AEF match, trainee experience, and postfellowship employment. METHODS ASGE AEF match data from 2012 to 2020 were reviewed. Online surveys were sent to advanced endoscopy trainees in 2019 and 2020 to explore their perceptions about AEF training and postfellowship jobs. RESULTS Data for 2020 showed 19% of matched applicants were women, 55% foreign medical graduates, and 17.5% U.S. visa holders. The number of AEF match applicants increased by 15.6% (90 in 2012 to 104 in 2020) and number of AEF programs increased by 23.5% (51 in 2012 to 63 in 2020). The average applicant match rate was 57% (range, 52.8%-60.6%) and position match rate 87.9% (range, 79.1%-94.6%). Ninety-one percent of trainees (n = 58) rated the quality of their training as very good/excellent; 75% of trainees participated in >300 ERCPs and 64.1% in >300 EUS cases. Seventy percent of trainees reported that advanced endoscopic procedures comprised ≤50% of their procedure volume in their first job, and 71.9% believed it was not easy to find a job after fellowship; however, 97% believed they would make the same decision to pursue AEF training again. CONCLUSIONS There has been a steady increase in the number of advanced endoscopy applicants and training positions over recent years. Most graduating fellows reported 50% or less of their upcoming clinical practice would involve advanced endoscopic procedures. Future studies are needed to further clarify employment opportunities and personnel needs for advanced endoscopists.

Abstract
BACKGROUND Flexible endoscopic myotomy has been increasingly performed for Zenker's diverticulum using various endoscopic techniques and devices. The main aims of this study were to assess practice patterns and compare outcomes of endoscopic myotomy for Zenker's diverticulum. METHODS Procedures performed at 12 tertiary endoscopy centers from 1/2012 to 12/2018 were reviewed. Patients (≥ 18 years) with Zenker's diverticulum who had dysphagia and/or regurgitation and underwent endoscopic myotomy were included. Outcomes assessed included technical success, clinical success, and adverse events. RESULTS 161 patients were included. Traditional endoscopic septotomy was performed most frequently (137/161, 85.1 %) followed by submucosal dissection of the septum and myotomy (24/161, 14.9 %). The hook knife (43/161, 26.7 %) and needle-knife (33/161, 20.5 %) were used most frequently. Overall, technical and clinical success rates were 98.1 % (158/161) and 78.1 % (96/123), respectively. Adverse events were noted in 13 patients (8.1 %). There was no significant difference in technical and clinical success between traditional septotomy and submucosal dissection groups (97.1 % vs. 95.8 %, P = 0.56 and 75.2 % vs. 90.9 %, P = 0.16, respectively). Clinical success was higher with the hook knife (96.7 %) compared with the needle-knife (76.6 %) and insulated tip knife (47.1 %). Outcomes were similar between centers performing > 20, 11 - 20, and ≤ 10 procedures. CONCLUSIONS Flexible endoscopic myotomy is an effective therapy for Zenker's diverticulum, with a low rate of adverse events. There was no significant difference in outcomes between traditional septotomy and a submucosal dissection approach, or with centers with higher volume, though clinical success was higher with the hook knife.

Abstract
BACKGROUND Biliary stricture evaluation with brush cytology and intraductal forceps biopsy carries a low sensitivity, but the combination of newer modalities may improve sensitivity. AIM To determine whether the addition of advanced modalities increases diagnostic yield of ERCP-based sampling. METHODS This single-center retrospective study evaluates patients with biliary strictures sampled using brush cytology. Operating characteristics were calculated for individual and combinations of modalities including cholangioscopy, fluoroscopy- and cholangioscopy-directed intraductal biopsy, fluorescence in situ hybridization (FISH), and confocal laser endomicroscopy. Analyses under Standard Criteria (SC) included malignant results as "positive" and Expanded Criteria (EC) included "suspicious" and "high-grade dysplasia" results as "positive." RESULTS A total of 614 patients were included, and 354 (57.8%) received brush cytology alone, which had a sensitivity of 38.5% (SC) to 40.3% (EC) and a specificity of 97.8% (EC) to 99.3% (SC). Combining brush cytology with fluoroscopy-guided biopsy (n = 259, 42.2%) had a sensitivity of 62.5% (SC) to 67.9% (EC) and specificity of 90.2% (EC) to 96.7% (SC). Adding FISH to brush cytology had a sensitivity of 84.2% (SC) to 87.5% (EC) and specificity of 54.1% (SC and EC), while cholangioscopy visualization addition resulted in a sensitivity of 80.4% (SC) to 92.2% (EC) and specificity of 67.3% (EC) to 89.1% (SC). There were no significant differences in sensitivity and specificity using SC and EC. CONCLUSIONS Brush cytology has a low sensitivity, but the addition of other modalities increases sensitivity. There was no difference in specificity between the SC and the EC, supporting the inclusion of "suspicious" impressions with malignant results at our center.

Abstract
OBJECTIVES Data regarding the safety of endoscopic retrograde pancreatography (ERP) are limited compared with biliary endoscopic retrograde cholangiopancreatography. The aim of this study was to determine adverse events (AEs) associated with therapeutic ERP. METHODS This single-center retrospective study examined consecutive therapeutic ERPs with the primary intention of cannulating the pancreatic duct. Multivariate logistic regression was performed to identify risk factors for AEs. RESULTS A total of 3023 ERPs were performed in 1288 patients (mean age, 50.3 years; 57.8% female) from January 2000 to January 2017. Overall AE rate was 18.9% with abdominal pain requiring admission (9.8%) and post-ERP pancreatitis (5.7%) being most common. On multivariate analysis, female sex (adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.9-2.9), acute recurrent pancreatitis (aOR, 5.0; 95% CI, 1.7-15.3), chronic pancreatitis (aOR, 1.8; 95% CI, 1.3-2.6), and pancreatic sphincter of Oddi dysfunction (aOR, 2.1; 95% CI, 1.4-3.3) were associated with an increased risk of overall AEs. Pancreatic sphincterotomy (aOR, 1.9; 95% CI, 1.5-2.4) and therapeutic stenting (aOR, 1.6; 95% CI, 1.2-2.2) also increased the risk of AEs. CONCLUSIONS Nearly 1 in 5 patients who undergo therapeutic ERP will experience an AE; however, the rates of major AEs, including post-ERP pancreatitis, bleeding, and perforation, are low.
