RÉSUMÉ
BACKGROUND: Radial probe endobronchial ultrasound (radial EBUS) is widely used to diagnose pulmonary lesions; however, the diagnostic value of radial EBUS-guided transbronchial biopsy (TBB) varies, and its complications (especially the risk of bleeding) are not properly understood. OBJECTIVES: In this study, we evaluated the diagnostic performance and rate of complication of this procedure, and investigated the risk factors associated with the procedure-related bleeding events. DESIGN: A retrospective cohort study. METHODS: This was a retrospective study that included consecutive patients who underwent radial EBUS-guided TBB. Radial EBUS was performed under moderate sedation in inpatients or outpatients. The severity of bleeding was graded using the standardized definitions of bleeding. RESULTS: Of 133 patients (median age, 69 years; men 57.1%) included, 41 were outpatients (30.8%). The diagnostic accuracy, sensitivity, and specificity for malignancy were 76.1% (89/117), 71.1% (69/97), and 100% (20/20), respectively. The diagnostic accuracy ranged from 66.9% to 79.0%, depending on the classification of undiagnosed cases as either false negatives or true negatives. Twenty-seven patients (20.3%) developed complications (pneumothorax, 3; pneumonia, 5; complicated pleural effusion, 2; bleeding event grade 2 or higher, 21). Of the 41 outpatients, two developed complications (pneumothorax without intervention, 1; grade 2 bleeding event, 1). Of the 21 patients (15.8%) with procedure-related bleeding events, 18 had grade 2, and three had grade 3 bleeding complications. In multivariate analysis, a large size of ⩾30 mm (adjusted odds ratio (OR), 5.09; p = 0.03) and central lesion (adjusted OR, 3.67; p = 0.03) were significantly associated with the risk of grade 2 or higher bleeding events. CONCLUSION: Our results suggest that radial EBUS-guided TBB is an accurate and safe method for diagnosing pulmonary lesions. Clinically significant procedure-related bleeding was rare. The central location and larger size (⩾30 mm) of pulmonary lesions were risk factors for grade 2 or higher bleeding events.

INTRODUCTION: Transbronchial needle aspiration guided by endobronchial ultrasonography (EBUSTBNA) has the disadvantage of sometimes offering samples of an unsuitable size for an accurate histo-molecular diagnosis. Transbronchial mediastinal cryobiopsy (CRYOEBUS) is a very novel and additional technique to EBUS-TBNA that allows us to obtain larger and quality samples, improving diagnostic performance. MATERIAL AND METHODS: Descriptive study of 110 patients with lesions and/or mediastinal lymphadenopathy who underwent EBUS-TBNA and CRYO-EBUS in a single procedure. Our objective was to analyze the diagnostic profitability and safety of the technique. RESULTS: CRYO-EBUS obtained samples of 0.42cm on average compared to 0.14cm obtained by EBUS-TBNA. The overall diagnostic performance of the techniques was 60% for EBUS-TBNA and 94.5% for CRYO-EBUS. Furthermore, the latter was more sensitive for the diagnosis of both malignant and benign diseases. With a very high security profile. CONCLUSIONS: The CRYO-EBUS technique is cost-effective and safe, and is superior to EBUS-TBNA. Future studies may confirm our findings.

In the last decades, Endoscopic ultrasound (EUS) has rapidly grown and evolved from being mainly a diagnostic procedure, to being an interventional and therapeutic tool in several pathological clinical scenarios. With the progressive growth in technical expertise and dedicated devices, interventional endoscopic ultrasound procedures (IEUSP) have shown high rates of technical and clinical success, together with a relatively safe profile. However, the description and the standardization of different and specific types of adverse events (AEs) are still scarce in literature, and, consequently, even less the management of AEs. The aim of this study is to critical review and to describe AEs related to each of the main IEUSP, and to provide an overview on the possible management strategies of endoscopic complications. Future studies and guidelines are surely required to reach a better standardization of different AEs and their best management.

OBJECTIVE: This study aimed to systematically evaluate the efficacy and safety of Endoscopic Ultrasonography (EUS) for the treatment of pancreatic cancer. METHODS: The PubMed, Embase, Web of Science, and Google Scholar databases were searched from the inception of the databases to June 2022. RevMan 5.3.0 software was utilized for data analysis. In total, 13 self-descriptive studies, which enrolled 382 patients, were finally included. RESULTS: It was revealed that EUS for the treatment of pancreatic cancer exhibited a lower incidence of adverse reactions (Relative Risk Ration [RR = 0.23], 95 % Confidence interval [95 % CI 0.23-0.23]), a higher success rate (RR = 0.90, 95 % CI 0.90-0.90), and a low failure rate (RR = 0.06, 95 % CI 0.06-0.06). Moreover, EUS-guided Celiac Plexus Neurolysis (EUS-CPN) not only significantly relieved pancreatic cancer patients' pain (RR = 0.83, 95 % CI 0.83-0.83), but also significantly eliminated pain in some patients (RR = 0.09, 95 % CI 0.09-0.09). The effects of EUS on pancreatic cancer treatment were satisfactory, and few adverse reactions were found. CONCLUSION: Owing to the restricted sample size in this meta-analysis, primarily consisting of descriptive studies, it was imperative to conduct more rigorously designed, multi-center, long-term follow-up, larger sample, and Randomized Controlled Trials (RCTs) to validate the findings.

Gastric outlet obstruction (GOO) poses a common and challenging clinical scenario, characterized by mechanical blockage in the pylorus, distal stomach, or duodenum, resulting in symptoms such as nausea, vomiting, abdominal pain, and early satiety. Its diverse etiology encompasses both benign and malignant disorders. The spectrum of current treatment modalities extends from conservative approaches to more invasive interventions, incorporating procedures like surgical gastroenterostomy (SGE), self-expandable metallic stents (SEMSs) placement, and the advanced technique of endoscopic ultrasound-guided gastroenterostomy (EUS-GE). While surgery is favored for longer life expectancy, stents are preferred in malignant gastric outlet stenosis. The novel EUS-GE technique, employing a lumen-apposing self-expandable metal stent (LAMS), combines the immediate efficacy of stents with the enduring benefits of gastroenterostomy. Despite its promising outcomes, EUS-GE is a technically demanding procedure requiring specialized expertise and facilities.

INTRODUCTION: Endoscopic ultrasound (EUS)-guided drainage of symptomatic pancreatic fluid collections (PFCs) using the Hot-Axios device has recently been associated with a significant risk of bleeding. This adverse event (AE) seems to occur less frequently with the use of a different device, the Spaxus stent. The aim of the current study was to compare the rates of bleeding between the two stents. METHODS: Patients admitted for treatment of PFCs by EUS plus lumen-apposing metal stent in 18 endoscopy referral centers between 10 July 2019 and 28 February 2022 were identified and their outcomes compared using a propensity-matching analysis. RESULTS: 363 patients were evaluated. After a 1-to-1 propensity score match, 264 patients were selected (132 per group). The technical and clinical success rates were comparable between the two groups. Significantly more bleeding requiring transfusion and/or intervention occurred in the Hot-Axios group than in the Spaxus group (6.8% vs. 1.5%; Pâ=â0.03); stent type was a significant predictor of bleeding in both univariate and multivariate regression analyses (Pâ=â0.03 and 0.04, respectively). Bleeding necessitating arterial embolization did not however differ significantly between the two groups (3.0% vs. 0%; Pâ=â0.12). In addition, the Hot-Axios was associated with a significantly higher rate of overall AEs compared with the Spaxus stent (9.8% vs. 3.0%; Pâ=â0.04). CONCLUSION: Our study showed that, in patients with PFCs, bleeding requiring transfusion and/or intervention occurred significantly more frequently with use of the Hot-Axios stent than with the Spaxus stent, although this was not the case for bleeding requiring embolization.

PURPOSE: Endoscopic ultrasound-guided gastro-enterostomy (EUS-GE) is a relatively novel technique that has been shown to require less re-intervention than standard endoscopic enteral stenting for gastric outlet obstruction and is less invasive, quicker, and more cost-effective than surgery. This study evaluated the outcomes and safety of EUS-GE in patients treated for gastric outlet obstruction across two Australian centers. METHODS: Retrospective data on demographics, presenting symptoms, disease, endoscopic and clinical outcomes, and safety were collected on all patients who underwent EUS-GE from 2021 to 2022. Descriptive statistics were used to evaluate outcomes and safety and survival were calculated using Kaplan-Meier analysis. RESULTS: Eleven patients underwent EUS-GE during the defined period, 10 of whom had a malignant etiology (median age 73 years, interquartile range [IQR] 13; 63.6% male). Technical success was 90.9%. Of those patients, clinical success (the ability to tolerate at least a full liquid diet during follow-up) was 100%. The median length of hospital stay post-procedure was 6 days (IQR 14 days). No severe adverse events occurred, and one patient (10%) required a repeat endoscopy. Median survival post-EUS-GE was 298 days (95% confidence interval 0-730.1 days) CONCLUSION: EUS-GE is an effective, safe, and durable therapy for patients with gastric outlet obstruction. This study presents Australian data on outcomes and safety that is comparable to international literature. EUS-GE should be considered for patients where local expertise allows.

BACKGROUND AND AIM: This study aimed to determine safety and risk factors for adverse events (AEs) of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) with long-term indwell of lumen-apposing metal stents (LAMS). METHODS: This study is a multicenter prospective observational study on consecutive high surgical-risk patients requiring gallbladder drainage who underwent EUS-GBD with LAMS over 12 months. Centralized telephone follow-up interviews were conducted every 3 months for 1 year. Patients were censored at LAMS removal, cholecystectomy, or death. AE-free survival was determined using log-rank tests. Cumulative risks were estimated using life-table analysis. RESULTS: Eighty-two patients were included (53.7% male, median [interquartile range] age of 84.6 [76.5-89.8] years, and 85.4% with acute cholecystitis). Technical success was achieved in 79 (96.3%), and clinical success in 73 (89%). No patient was lost to follow-up; 45 patients (54.9%) completed 1-year follow-up with in situ LAMS. Median (interquartile range) LAMS indwell time was 364 (47-367) days. Overall, 12 (14.6%) patients presented 14 AEs, including 5 (6.1%) recurrent biliary events (3 acute cholangitis, 1 mild acute pancreatitis, and 1 acute cholecystitis). Patients with pancreatobiliary malignancy had an increased risk of recurrent biliary events (33% vs 1.5%, P = 0.001). The overall 1-year cumulative risk of recurrent biliary events was 9.7% (4.1-21.8%). The 1-year risk of AEs and of severe AEs was 18.8% (11-31.2%) and 7.9% (3.3-18.2%), respectively. Pancreatobiliary malignancy was the single risk factor for recurrent biliary events; LAMS misdeployment was the strongest risk factor for AEs. CONCLUSIONS: Long-term LAMS indwell does not increase the risk of delayed AEs following EUS-GBD.

Endoscopic retrograde cholangiopancreatography (ERCP) has been established as the first line therapy for the resolution of biliary and pancreatic diseases. The main disadvantage of the procedure is the rate of adverse events, around 10%1. So, despite being a minimally invasive procedure, ERCP has a non-negligible rate of adverse effects (AEs) and secondary mortality.

BACKGROUND AND AIMS: Despite the significant morbidity associated with gastric variceal bleeding, there is a paucity of high-quality data regarding optimal management. EUS-guided coil injection therapy (EUS-COIL) has recently emerged as a promising endoscopic modality for the treatment of gastric varices (GV), particularly compared with traditional direct endoscopic glue injection. Although there are data on the feasibility and safety of EUS-COIL in the management of GV, these have been limited to select centers with particular expertise. The aim of this study was to report the first U.S. multicenter experience of EUS-COIL for the management of GV. METHODS: This retrospective analysis included patients with bleeding GV or GV at risk of bleeding who underwent EUS-COIL at 10 U.S. tertiary care centers between 2018 and 2022. Baseline patient and procedure-related information was obtained. EUS-COIL entailed the injection of .018 inch or .035 inch hemostatic coils using a 22-gauge or 19-gauge FNA needle. Primary outcomes were technical success (defined as successful deployment of coil into varix under EUS guidance with diminution of Doppler flow), clinical success (defined as cessation of bleeding if present and/or absence of bleeding at 30 days' postintervention), and intraprocedural and postprocedural adverse events. RESULTS: A total of 106 patients were included (mean age 60.4 ± 12.8 years; 41.5% female). The most common etiology of GV was cirrhosis (71.7%), with alcohol being the most common cause (43.4%). Overall, 71.7% presented with acute GV bleeding requiring intensive care unit stay and/or blood transfusion. The most common GV encountered were isolated GV type 1 (60.4%). A mean of 3.8 ± 3 coils were injected with a total mean length of 44.7 ± 46.1 cm. Adjunctive glue or absorbable gelatin sponge was injected in 82% of patients. Technical success and clinical success were 100% and 88.7%, respectively. Intraprocedural adverse events (pulmonary embolism and GV bleeding from FNA needle access) occurred in 2 patients (1.8%), and postprocedural adverse events occurred in 5 (4.7%), of which 3 were mild. Recurrent bleeding was observed in 15 patients (14.1%) at a mean of 32 days. Eighty percent of patients with recurrent bleeding were successfully re-treated with repeat EUS-COIL. No significant differences were observed in outcomes between high-volume (>15 cases) and low-volume (<7 cases) centers. CONCLUSIONS: This U.S. multicenter experience on EUS-COIL for GV confirms high technical and clinical success with low adverse events. No significant differences were seen between high- and low-volume centers. Repeat EUS-COIL seems to be an effective rescue option for patients with recurrent bleeding GV. Further prospective studies should compare this modality versus other interventions commonly used for GV.

Predictive models (PMs) in endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) have the potential to improve patient outcomes, enhance diagnostic accuracy, and guide therapeutic interventions. This review aims to summarize the current state of predictive models in ERCP and EUS and their clinical implications. To be considered useful in clinical practice a PM should be accurate, easy to perform, and may consider objective variables. PMs in ERCP estimate correct indication, probability of success, and the risk of developing adverse events. These models incorporate patient-related factors and technical aspects of the procedure. In the field of EUS, these models utilize clinical and imaging data to predict the likelihood of malignancy, presence of specific lesions, or risk of complications related to therapeutic interventions. Further research, validation, and refinement are necessary to maximize the utility and impact of these models in routine clinical practice.

Lung cancer is usually diagnosed at advanced stage and systematic therapy is administered. New current diagnostic techniques such as the convex-endobronchial ultrasound, radial endobronchial ultrasound, cone beam ct, electromagnetic navigation and robotic bronchoscopy provide us with a high diagnostic yield. These techniques are minimal invasive and patients with comorbidities such as chronic obstructive pulmonary disease and heart failure can be diagnosed with minimal adverse effects. All these techniques provide sufficient sample for molecular investigation. Since immunotherapy was first administered, we have more and more information regarding the appropriate patient target group. Several published studies divided patients as elderly ≥75 and non-elderly ≤74 and investigated the adverse effects of different drugs and survival. In our current commentary we present information on patients receiving immunotherapy versus chemoimmunotherapy in two groups of elderly and non-elderly. Elderly patients can receive both combinations without differences between the two groups, however; more studies are needed to clarify certain aspects.

BACKGROUND AND AIMS: Multiple meta-analyses have evaluated the technical and clinical success of EUS-guided biliary drainage (BD), but meta-analyses concerning adverse events (AEs) are limited. The present meta-analysis analyzed AEs associated with various types of EUS-BD. METHODS: A literature search of MEDLINE, Embase, and Scopus was conducted from 2005 to September 2022 for studies analyzing the outcome of EUS-BD. The primary outcomes were incidence of overall AEs, major AEs, procedure-related mortality, and reintervention. The event rates were pooled using a random-effects model. RESULTS: One hundred fifty-five studies (7887 patients) were included in the final analysis. The pooled clinical success rates and incidence of AEs with EUS-BD were 95% (95% confidence interval [CI], 94.1-95.9) and 13.7% (95% CI, 12.3-15.0), respectively. Among early AEs, bile leak was the most common followed by cholangitis with pooled incidences of 2.2% (95% CI, 1.8-2.7) and 1.0% (95% CI, .8-1.3), respectively. The pooled incidences of major AEs and procedure-related mortality with EUS-BD were .6% (95% CI, .3-.9) and .1% (95% CI, .0-.4), respectively. The pooled incidences of delayed migration and stent occlusion were 1.7% (95% CI, 1.1-2.3) and 11.0% (95% CI, 9.3-12.8), respectively. The pooled event rate for reintervention (for stent migration or occlusion) after EUS-BD was 16.2% (95% CI, 14.0-18.3; I2 = 77.5%). CONCLUSIONS: Despite a high clinical success rate, EUS-BD may be associated with AEs in one-seventh of the cases. However, major AEs and mortality incidence remain less than 1%, which is reassuring.

BACKGROUND: The introduction of lumen-apposing metal stents (LAMS) for endoscopic ultrasound (EUS)-guided drainages has marked a turning point in the field of interventional ultrasound and it is gathering worldwide diffusion in different clinical settings. Nevertheless, the procedure may conceal unexpected pitfalls. LAMS misdeployment is the most frequent cause of technical failure and it can be considered a procedure-related adverse event when it hampers the conclusion of the planned procedure or results in significant clinical consequences. Stent misdeployment can be managed successfully by endoscopic rescue maneuvers to allow the completion of the procedure. To date, no standardized indication is available to guide an appropriate rescue strategy depending on the type of procedure or of misdeployment. AIM: To evaluate the incidence of LAMS misdeployment during EUS-guided choledochoduodenostomy (EUS-CDS), gallbladder drainage (EUS-GBD) and pancreatic fluid collections drainage (EUS-PFC) and to describe the endoscopic rescue strategies adopted under the circumstance. METHODS: We conducted a systematic review of the literature on PubMed by searching for studies published up to October 2022. The search was carried out using the exploded medical subject heading terms "lumen apposing metal stent", "LAMS", "endoscopic ultrasound" and "choledochoduodenostomy" or "gallbladder" or "pancreatic fluid collections". We included in the review on-label EUS-guided procedures namely EUS-CDS, EUS-GBD and EUS-PFC. Only those publications reporting EUS-guided LAMS positioning were considered. The studies reporting a technical success rate of 100% and other procedure-related adverse events were considered to calculate the overall rate of LAMS misdeployment, while studies not reporting the causes of technical failure were excluded. Case reports were considered only for the extraction of data regarding the issues of misdeployment and rescue techniques. The following data were collected from each study: Author, year of publication, study design, study population, clinical indication, technical success, reported number of misdeployment, stent type and size, flange misdeployed and type of rescue strategy. RESULTS: The overall technical success rate of EUS-CDS, EUS-GBD and EUS-PFC was 93.7%, 96.1%, and 98.1% respectively. Significant rates of LAMS misdeployment have been reported for EUS-CDS, EUS-GBD and EUS-PFC drainage, respectively 5.8%, 3.4%, and 2.0%. Endoscopic rescue treatment was feasible in 86.8%, 80%, and 96.8% of cases. Non endoscopic rescue strategies were required only in 10.3%, 16% and 3.2% for EUS-CDS, EUS-GBD, and EUS-PFC. The endoscopic rescue techniques described were over-the-wire deployment of a new stent through the created fistula tract in 44.1%, 8% and 64.5% and stent-in-stent in 23.5%, 60%, and 12.9%, respectively for EUS-CDS, EUS-GBD, and EUS-PFC. Further therapeutic option were endoscopic rendezvous in 11.8% of EUS-CDS and repeated procedure of EUS-guided drainage in 16.1% of EUS-PFC. CONCLUSION: LAMS misdeployment is a relatively common adverse event in EUS-guided drainages. There is no consensus on the best rescue approach in these cases and the choice is often made by the endoscopist relying upon the clinical scenario, anatomical characteristics, and local expertise. In this review, we investigated the misdeployment of LAMS for each of the on-label indications focusing on the rescue therapies used, with the aim of providing useful data for endoscopists and to improve patient outcomes.

BACKGROUND: Endoscopic ultrasound (EUS)-guided tissue acquisition (TA) is widely used for various target samples, but its efficacy in gallbladder (GB) lesions is unknown. The aim of the present meta-analysis was to assess the pooled adequacy, accuracy and safety of EUS-TA of GB lesions. METHODS: A literature search from January 2000 to August 2022 was done for studies analyzing the outcome of EUS-guided TA in patients with GB lesions. Pooled event rates were expressed with summative statistics. RESULTS: The pooled rate of sample adequacy for all GB lesions and malignant GB lesions was 97.0% (95% CI: 94.5-99.4) and 96.6% (95% CI: 93.8-99.3), respectively. The pooled sensitivity and specificity for the diagnosis of malignant lesions were 90% (95% CI: 85-94; I2 = 0.0%) and 100% (95% CI: 86-100; I2 = 0.0%), respectively, with an area under the curve of 0.915. EUS-guided TA had a pooled diagnostic accuracy rate of 94.6% (95% CI: 90.5-96.6) for all GB lesions and 94.1% (95% CI: 91.0-97.2) for malignant GB lesions. There were six reported mild adverse events (acute cholecystitis = 1, self-limited bleeding = 2, self-limited episode of pain = 3) with a pooled incidence of 1.8% (95% CI: 0.0-3.8) and none of the patients had serious adverse events. CONCLUSION: EUS-guided tissue acquisition from GB lesions is a safe technique with high sample adequacy and diagnostic accuracy. EUS-TA can be an alternative when traditional sampling techniques fail or are not feasible.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) may fail to achieve biliary drainage in 5% to 10% of cases. Endoscopic ultrasound-guided biliary drainage (EUS-BD) and percutaneous transhepatic biliary drainage (PTBD) are alternative therapeutic options in such cases. The present meta-analysis aimed to compare the efficacy and safety of EUS-BD and PTBD for biliary decompression after failed ERCP. METHODS: A comprehensive search of literature from inception to September 2022 was done of 3 databases for studies comparing EUS-BD and PTBD for biliary drainage after failed ERCP. Odds ratios (ORs) with 95% CIs were calculated for all the dichotomous outcomes. Continuous variables were analyzed using mean difference (MD). RESULTS: A total of 24 studies were included in the final analysis. Technical success was comparable between EUS-BD and PTBD (OR=1.12, 0.67-1.88). EUS-BD was associated with a higher clinical success rate (OR=2.55, 1.63-4.56) and lower odds of adverse events (OR=0.41, 0.29-0.59) compared with PTBD. The incidence of major adverse events (OR=0.66, 0.31-1.42) and procedure-related mortality (OR=0.43, 0.17-1.11) were similar between the groups. EUS-BD was associated with lower odds of reintervention with an OR of 0.20 (0.10-0.38). The duration of hospitalization (MD: -4.89, -7.73 to -2.05) and total treatment cost (MD: -1355.46, -2029.75 to -681.17) were significantly lower with EUS-BD. CONCLUSIONS: EUS-BD may be preferred over PTBD in patients with biliary obstruction after failed ERCP where appropriate expertise is available. Further trials are required to validate the findings of the study.

BACKGROUND: There has been great progress in the use of endoscopic ultrasound (EUS)-guided drainage in acute pancreatitis patients using a novel lumen-apposing metal stent (LAMS) in the last decade, but some patients experience bleeding. Our research analyzed the preprocedural risk factors for bleeding. METHODS: From July 13, 2016 to June 23, 2021, we retrospectively analyzed all patients who received endoscopic drainage by the LAMS in our hospital. Univariate and multivariate statistical analyses were used to identify the independent risk factors. We plotted ROC curves based on the independent risk factors. RESULTS: A total of 205 patients were analyzed and 5 patients were excluded. A total of 200 patients were included in our research. Thirty (15%) patients presented with bleeding. In the multivariate analysis, computed tomography severity index score (CTSI) score [odds ratio (OR), 2.66; 95% CI: 1.31-5.38; P = 0.007], positive blood cultures [odds ratio (OR), 5.35; 95% CI: 1.31-21.9; P = 0.02], and Acute Physiology and Chronic Health Evaluation II (APACHE II) score [odds ratio (OR), 1.14; 95% CI: 1. 01-1.29; P = 0.045] were associated with bleeding. The area under the ROC curve of the combined predictive indicator was 0.79. CONCLUSION: Bleeding in endoscopic drainage by the LAMS is significantly associated with the CTSI score, positive blood cultures, and APACHE II score. This result could help clinicians make more appropriate choices.

Objective: To analyze the risk factors for complications of endoscopic full-thickness resection (EFTR) of upper gastrointestinal submucosal tumors (SMTs). Methods: This was a retrospective observational study. The indications for EFTR included: (1) SMTs originating from the muscularis propria layer and growing out of the cavity or infiltrating the deep part of the muscularis propria layer; (2) SMTs diameter <5 cm; and (3) tumor identified as closely adherent to the serous layer during endoscopic submucosal dissection or endoscopic mucosal resection. This study included patients with SMTs originating from the muscularis propria layer in upper digestive tract, diagnosed preoperatively by endoscopic ultrasonography or computed tomography, who were successfully treated with EFTR. Those with incomplete clinical data were excluded. The clinical data of 154 patients with upper gastrointestinal SMTs who underwent EFTR at the Department of Gastroenterology, First Affiliated Hospital of Soochow University from January 2016 to January 2022 were retrospectively analyzed. Post-EFTR complications (such as delayed perforation, delayed bleeding, and postoperative infection, including electrocoagulation syndrome) were monitored and the risk factors for them were analyzed. Results: Among the 154 study patients, 33 (21.4%) developed complications, including delayed bleeding in three (1.9%), delayed perforation in two (1.3%), and postoperative infection in 28 (18.2%). One patient with bleeding was classified as having a major complication (hospitalized for more than 10 days because of complication). According to univariate analysis, complication was associated with tumor diameter >15 mm, operation time >90 minutes, defect closure method(purse string suture), and diameter of resected specimen ≥20 mm (all P<0.05). Multivariate logistic regression analysis showed that operation time >90 minutes (OR=6.252, 95%CI: 2.530-15.446, P<0.001) and tumor diameter >15 mm (OR=4.843, 95%CI: 1.985-11.817, P=0.001) were independent risk factors for complications after EFTR in patients with upper gastrointestinal SMTs. The independent risk factors for postoperative infection in these patients were operation time>90 minutes (OR=4.993, 95%CI:1.964-12.694, P=0.001) and purse string suture (OR=7.142, 95%CI: 1.953-26.123, P=0.003). Conclusion: Patients with upper gastrointestinal SMTs undergoing EFTR with tumor diameter >15 mm or operation time >90 minutes have a significantly increased risk of postoperative complications. Postoperative monitoring is important for these patients with SMTs.

Importance: The incidence of chronic pancreatitis is 5 to 12 per 100â¯000 adults in industrialized countries, and the incidence is increasing. Treatment is multimodal, and involves nutrition optimization, pain management, and when indicated, endoscopic and surgical intervention. Objectives: To summarize the most current published evidence on etiology, diagnosis, and management of chronic pancreatitis and its associated complications. Evidence Review: A literature search of Web of Science, Embase, Cochrane Library, and PubMed was conducted for publications between January 1, 1997, and July 30, 2022. Excluded from review were the following: case reports, editorials, study protocols, nonsystematic reviews, nonsurgical technical publications, studies pertaining to pharmacokinetics, drug efficacy, pilot studies, historical papers, correspondence, errata, animal and in vitro studies, and publications focused on pancreatic diseases other than chronic pancreatitis. Ultimately, the highest-level evidence publications were chosen for inclusion after analysis by 2 independent reviewers. Findings: A total of 75 publications were chosen for review. First-line imaging modalities for diagnosis of chronic pancreatitis included computed tomography and magnetic resonance imaging. More invasive techniques such as endoscopic ultrasonography allowed for tissue analysis, and endoscopic retrograde cholangiopancreatography provided access for dilation, sphincterotomy, and stenting. Nonsurgical options for pain control included behavior modification (smoking cessation, alcohol abstinence), celiac plexus block, splanchnicectomy, nonopioid pain medication, and opioids. Supplemental enzymes should be given to patients with exocrine insufficiency to avoid malnutrition. Surgery was superior to endoscopic interventions for long-term pain control, and early surgery (<3 years from symptom onset) had more superior outcomes than late surgery. Duodenal preserving strategies were preferred unless there was suspicion of cancer. Conclusions and Relevance: Results of this systematic review suggest that patients with chronic pancreatitis had high rates of disability. Strategies to improve pain control through behavioral modification, endoscopic measures, and surgery must also accompany management of the sequalae of complications that arise from endocrine and exocrine insufficiency.
