Endoscopic duodenal stenting is the current standard treatment for malignant gastric outlet obstruction (GOO) in patients with limited life expectancy. However, duodenal stenting is prone to stent ...dysfunction. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is a novel technique with potentially superior stent patency. We compared clinical success, safety, and stent dysfunction of EUS-GE and duodenal stenting in patients with malignant GOO using propensity score matching.
This international, multicenter, retrospective study analyzed consecutive patients undergoing EUS-GE or duodenal stenting for GOO between 2015 and 2021 in three European centers. Primary outcomes were clinical success (GOO scoring system GOOSS ≥ 2) and stent dysfunction (GOOSS ≤ 1 after initial clinical success). A propensity score matching (1:1) analysis was performed using age, sex, underlying disease, disease stage, ascites, and peritoneal carcinomatosis as variables.
214 patients underwent EUS-GE (n = 107) or duodenal stenting (n = 107). After propensity score matching, 176 patients were matched and compared. Technical success rates for EUS-GE and duodenal stenting were 94 % (95 %CI 89 %-99 %) vs. 98 % (95 %CI 95 %-100 %), respectively (
= 0.44). Clinical success rates were 91 % (95 %CI 85 %-97 %) vs. 75 % (95 %CI 66 %-84 %;
= 0.008). Stent dysfunction occurred in 1 % (95 %CI 0-4 %) vs. 26 % (95 %CI 15 %-37 %) of patients (
< 0.001). Adverse event rate was 10 % (95 %CI 4 %-17 %) vs. 21 % (95 %CI 12 %-29 %;
= 0.09).
EUS-GE had higher clinical success and lower stent dysfunction, with similar safety, compared with duodenal stenting, suggesting that EUS-GE may be preferred over duodenal stenting in patients with malignant GOO.
Background
Endoscopic vacuum therapy (EVT) represents an effective endoscopic technique for the treatment of post-esophagectomy leaks and can be used after failure of primary treatment. We aimed to ...investigate endoscopic data and success rate of EVT for post-esophagectomy anastomotic leaks, after failed redo surgery or previous endoscopic treatment.
Methods
We retrospectively recruited 12 patients from January 2018 to October 2020. Success was defined as dehiscence closure at radiological and/or endoscopic evaluation. Ethical Committee of our institution approved the study.
Results
Twelve patients (66.7% male, mean age 65.08 ± 16.7 years) affected by esophago-gastric (
n
= 10) or esophago-jejunal (
n
= 2) anastomosis dehiscences after oncologic surgery were treated with EVT, after failure of previous redo-surgical (
n
= 3, 25%) or endoscopic management (
n
= 9, 75%). Technical success rate was 100% (60/60 procedures) and dehiscence closure was achieved in three quarters of patients (9/12, 75%). Regarding complications, one case of sponge dislocation (1/60 = 1.7%) and another case of delayed stricture after post-EVT stent placement (1/60 = 1.7%) were recorded, during a mean follow up of 182.3 days.
Conclusions
EVT is a promising option in the treatment of the most complicated anastomotic dehiscences. Its use could be also considered after failure of previous endoscopic or surgical management.
Eosinophilic esophagitis (EoE) is a chronic immune-mediated rare disease, characterized by esophageal dysfunctions. It is likely to be primarily activated by food antigens and is classified as a ...chronic disease for most patients. Therefore, a deeper understanding of the pathogenetic mechanisms underlying EoE is needed to implement and improve therapeutic lines of intervention and ameliorate overall patient wellness.
RNA-seq data of 18 different studies on EoE, downloaded from NCBI GEO with faster-qdump ( https://github.com/ncbi/sra-tools ), were batch-corrected and analyzed for transcriptomics and metatranscriptomics profiling as well as biological process functional enrichment. The EoE TaMMA web app was designed with plotly and dash. Tabula Sapiens raw data were downloaded from the UCSC Cell Browser. Esophageal single-cell raw data analysis was performed within the Automated Single-cell Analysis Pipeline. Single-cell data-driven bulk RNA-seq data deconvolution was performed with MuSiC and CIBERSORTx. Multi-omics integration was performed with MOFA.
The EoE TaMMA framework pointed out disease-specific molecular signatures, confirming its reliability in reanalyzing transcriptomic data, and providing new EoE-specific molecular markers including CXCL14, distinguishing EoE from gastroesophageal reflux disorder. EoE TaMMA also revealed microbiota dysbiosis as a predominant characteristic of EoE pathogenesis. Finally, the multi-omics analysis highlighted the presence of defined classes of microbial entities in subsets of patients that may participate in inducing the antigen-mediated response typical of EoE pathogenesis.
Our study showed that the complex EoE molecular network may be unraveled through advanced bioinformatics, integrating different components of the disease process into an omics-based network approach. This may implement EoE management and treatment in the coming years.
Functional gastrointestinal disorders (FGIDs), also known as disorders of gut-brain interaction, are a group of disorders characterized by chronic gastrointestinal symptoms in the absence of ...demonstrable pathology on conventional testing ....
Endoscopic treatment of post-esophagectomy/gastrectomy anastomotic dehiscence includes Self-Expandable Metal Stents (SEMS), which have represented the "gold standard" for many years, and Endoscopic ...Vacuum Therapy (EVT), which was recently introduced, showing promising results. The aim of the study was to compare outcomes of SEMS and EVT in the treatment of post-esophagectomy/gastrectomy anastomotic leaks, focusing on oncologic surgery.
A systematic search was performed on Pubmed and Embase, identifying studies comparing EVT versus SEMS for the treatment of leaks after upper gastro-intestinal surgery for malignant or benign pathologies. The primary outcome was the rate of successful leak closure. A meta-analysis was conducted, performing an a priori-defined subgroup analysis for the oncologic surgery group.
Eight retrospective studies with 357 patients were eligible. Overall, the EVT group showed a higher success rate (odd ratio OR 2.58, 95% CI 1.43-4.66), a lower number of devices (pooled mean difference pmd 4.90, 95% CI 3.08-6.71), shorter treatment duration (pmd -9.18, 95% CI -17.05--1.32), lower short-term complication (OR 0.35, 95% CI 0.18-0.71) and mortality rates (OR 0.47, 95% CI 0.24-0.92) compared to stenting. In the oncologic surgery subgroup analysis, no differences in the success rate were found (OR 1.59, 95% CI 0.74-3.40, I
= 0%).
Overall, EVT has been revealed to be more effective and less burdened by complications compared to stenting. In the oncologic surgery subgroup analysis, efficacy rates were similar between the two groups. Further prospective data need to define a unique management algorithm for anastomotic leaks.
Background
Globally, the number of people aged 80 years or over, the “oldest old,” is the fastest growing population group. Because of the strong association between age and gallstone disease, both ...prevalence and incidence of this disease are increasing. The feasibility of the cholecystectomy in octogenarians has been evaluated in several studies that confirmed the safety of the operation. However, the safety of this procedure in nonagenarians is still controversial. The aim of this study was to evaluate the safety of cholecystectomies in nonagenarians and identify related predictors for postoperative hospital length of stay (LOS) and in-hospital mortality up to 30 days postoperatively.
Methods
More than 500 cholecystectomies, both open and laparoscopic, were performed between January 2000 and September 2015 at our institution in patients 80 years and older. These statistics include both elective and emergent admissions. A retrospective review of charts over the last 15 years was conducted to compare mortality and length of postoperative stay among two patient groups: 319 octogenarians and 36 nonagenarians. Parameters evaluated include demographics, surgical presentation, American Society of Anesthesiologists (ASA) score, main diagnosis, comorbidities, type of surgery performed, LOS and in-hospital mortality. All data were analyzed with STATA (v.13) software, using a multivariate logistic regression after determining the statistically significant variables through a stepwise regression.
Conclusions
We found out that being nonagenarian, compared to octogenarian, is not a significant risk factor in terms of LOS and in-hospital mortality within 30 days postoperatively. Despite that, the mortality rate among nonagenarians is still remarkably high as almost every patient was admitted in an emergent setting. The most remarkable predictor for mortality among the two groups was an “afternoon/night emergency” surgical presentation (OR 25.5, CI 1.53–42.35,
p
= 0.02). Thus, the surgical emergency management for gallbladder disease at our institution should be critically reevaluated. Performing the procedure in laparoscopy predicted a significant reduction (−5 days, CI −8.5 to −1.4,
p
= 0.006) of LOS, while presenting with “gallbladder and bile duct stones” (+6.3 days, CI 1.5–11.1,
p
= 0.01) or “acalculous cholecystitis” (+4.7 days, CI 0.4–9.2,
p
= 0.03) had the opposite effect. Despite the remarkable mortality rate of our series, being nonagenarian should not be considered as a reason to avoid gallbladder surgery in case of need. Our study suggests that nonagenarians are more suitable surgical candidates than may have previously expected.
Gastroparesis (GP) is a chronic disease characterized by upper gastrointestinal symptoms, primarily nausea and vomiting, and delayed gastric emptying (GE), in the absence of mechanical GI ...obstruction. The underlying pathophysiology of GP remains unclear, but factors contributing to the condition include vagal nerve dysfunction, impaired gastric fundic accommodation, antral hypomotility, gastric dysrhythmias, and pyloric dysfunction. Currently, gastric emptying scintigraphy (GES) is considered the gold standard for GP diagnosis. However, the overall delay in GE weakly correlates with GP symptoms and their severity. Recent research efforts have focused on developing treatments that address the presumed underlying pathophysiological mechanisms of GP, such as pyloric hypertonicity, with Gastric Peroral Endoscopic Myotomy (G-POEM) one of these procedures. New promising diagnostic tools for gastroparesis include wireless motility capsule (WMC), the 13 carbon-GE breath test, high-resolution electrogastrography, and the Endoluminal Functional Lumen Imaging Probe (EndoFLIP). Some of these tools assess alterations beyond GE, such as muscular electrical activity and pyloric tone. These modalities have the potential to characterize the pathophysiology of gastroparesis, identifying patients who may benefit from targeted therapies. The aim of this review is to provide an overview of the current knowledge on diagnostic pathways in GP, with a focus on the association between diagnosis, symptoms, and treatment.
