BACKGROUND AND AIMS: Gastric restriction techniques have recently emerged as minimally invasive bariatric procedures. Endoscopic sutured gastroplasty (ESG) with the Endomina (Endo Tools Therapeutics, Gosselies, Belgium) triangulation platform proved to be safe and effective for the treatment of class I and II obesity in prospective studies. In this registry, we aimed to further assess on a larger scale the safety and efficacy of the procedure in routine practice with a dedicated device. METHODS: This was a multicenter, observational, prospective post-market study including patients with obesity undergoing Endomina ESG. The primary safety outcome was the occurrence of serious adverse device effects (SADEs) at 12 months. The primary efficacy outcome was the technical success defined by completing the procedure without premature abortion owing to technical issues. The rates of procedure-related adverse events, weight loss outcomes, and quality of life changes were collected. RESULTS: A total of 142 patients underwent ESG in 3 centers from July 2020 to March 2023. Of these, 67 (mean body mass index, 38.5 ± 6.3 kg/m2) reached at least 12 months of follow-up up to October 2022. Technical success was 100%. No SADEs occurred. Seven mild procedure-related adverse events were reported overall. Mean percentage of excess weight loss and total body weight loss at 12 months' follow-up were 48.5% ± 38.6 and 15.3% ± 10.6, respectively (n = 67). Improved quality of life was observed following ESG. CONCLUSIONS: ESG is safe and effective, thus offering a satisfactory therapeutic option for a wide range of obese patients on a large scale.

PURPOSE: Obesity and its related severe comorbidities are increasing rapidly. The duodenal-jejunal bypass is an endoscopically implanted device (mimicking the Roux-en-Y gastric bypass) developed to support weight reduction and improve type 2 diabetes control. MATERIALS AND METHODS: Retrospective data analysis of consecutive patients undergoing duodenal-jejunal bypass (EndoBarrier®, DJB) implantation between 2013 and 2017 was performed to evaluate safety as well as short- and long-term efficacy. RESULTS: One hundred and twenty-one patients (mean BMI of 43.1 ± 7.2 kg/m2 and weight of 138.2 ± 28.6 kg) underwent DJB implantation. The mean dwelling time was 15.5 months, the mean total body weight loss (%TBWL) after explantation was 10.3% ± 7.9% (14.2 kg, p < 0.0001), and the mean BMI was 39.5 ± 7.3 kg/m2 (p < 0.0001). There was no significant weight gain 24 months after the explantation. Seventy-seven patients had type 2 diabetes mellitus (T2DM) with a mean HbA1c before implantation of 5.6% (n = 52). The mean HbA1c after explantation was 5.1% (p = 0.0001). Significant reductions in transaminase and lipid levels before and after explantation were observed. One complication occurred during implantation and another during explantation. In 16 patients, the device had to be extracted earlier than expected (7 for severe adverse events and 9 for adverse events; 13.2%). CONCLUSION: Despite an evident rate of adverse events, the DJB shows promise as a weight-loss procedure. Our results show that some patients implanted with the device maintained reduced weight even 24 months after explantation, while many improved T2DM control.

Gastrointestinální trakt představuje častou lokalitu pro dobře diferencované neuroendokrinní tumory (NET). Jejich výskyt u pacientů s ulcerózní kolitidou (UC) není častý, je však dobře dokumentovaný. Případný kauzální vztah mezi rozvojem NET a chronickým zánětem střevní sliznice či dysplázií epitelu nicméně zůstává nejasný. Výskyt NET v ileálním pouchi u pacientů s UC byl dosud popsán jen v několika kazuistických sděleních. Prezentujeme zde případ takovéhoto nádoru vznikajícího ve sliznici pouche u pacienta s UC asociovanou s primární sklerozující cholangoitidou, který podstoupil transplantaci jater a restorativní kolektomii s následnou ileální pouch-anální anastomózou. Popis případu je doplněn o přehled dostupné literatury.
Gastrointestinal tract is the most common locality for well-differentiated neuroendocrine tumors (NET). While their occurrence in patients with ulcerative colitis (UC) is uncommon, it has been well documented. However, the causal relationship between development of NET and chronic intestinal inflammation or dysplasia remains controversial. The presence of NET in the ileal pouch in UC patients has been described only in a few reports to date. In this article, we present a case of such a tumor arising in the pouch in a patient with primary sclerosing cholangitis-associated UC, who underwent a restorative proctocolectomy with ileal pouch anal anastomosis and liver transplantation. The case is supported by a review of a relevant literature.

BACKGROUND: Ulcerative colitis (UC) with concomitant primary sclerosing cholangitis (PSC) represents a distinct disease entity (PSC-UC). Mayo endoscopic subscore (MES) is a standard tool for assessing disease activity in UC but its relevance in PSC-UC remains unclear. AIM: To assess the accuracy of MES in UC and PSC-UC patients, we performed histological scoring using Nancy histological index (NHI). METHODS: MES was assessed in 30 PSC-UC and 29 UC adult patients during endoscopy. NHI and inflammation were evaluated in biopsies from the cecum, rectum, and terminal ileum. In addition, perinuclear anti-neutrophil cytoplasmic antibodies, fecal calprotectin, body mass index, and other relevant clinical characteristics were collected. RESULTS: The median MES and NHI were similar for UC patients (MES grade 2 and NHI grade 2 in the rectum) but were different for PSC-UC patients (MES grade 0 and NHI grade 2 in the cecum). There was a correlation between MES and NHI for UC patients (Spearman's r = 0.40, P = 0.029) but not for PSC-UC patients. Histopathological examination revealed persistent microscopic inflammation in 88% of PSC-UC patients with MES grade 0 (46% of all PSC-UC patients). Moreover, MES overestimated the severity of active inflammation in an additional 11% of PSC-UC patients. CONCLUSION: MES insufficiently identifies microscopic inflammation in PSC-UC. This indicates that histological evaluation should become a routine procedure of the diagnostic and grading system in both PSC-UC and PSC.

Cholestatická onemocnění jater se vyznačují progresivní povahou a omezenými možnostmi konzervativní léčby. Jedinou efektivní metodou léčby terminálního stadia je transplantace jater, která signifikantně prodlužuje dobu přežití pacientů. Transplantace jater je v současnosti indikována nejen u pacientů s chronickým jaterním selháním nebo hepatobiliární malignitou, ale také u pacientů se sníženou kvalitou života při symptomech z obstrukce žlučovodů. Péče po transplantaci jater je specifická zejména z důvodu přítomnosti imunitně asociovaných onemocnění, např. idiopatických střevních zánětů u pacientů s primární sklerozující cholangitidou. Rekurence základního onemocnění v jaterním štěpu je častou dlouhodobou komplikací, která může negativně ovlivnit přežití štěpu i celkovou délku života. Navzdory riziku rekurence jsou dlouhodobé výsledky transplantace jater pro cholestatické nemoci výborné, přičemž pacienti s těmito diagnózami dosahují delšího přežití ve srovnání s ostatními transplantovanými pacienty.
Cholestatic liver diseases are characterized by their progressive nature and limited conservative treatment options. Liver transplantation is the only effective method of treatment for the terminal stage. Before the era of liver transplantation, patients with cholestatic disease had a significantly reduced life expectancy. Liver transplantation is now indicated not only for patients with chronic liver failure or hepatobiliary malignancy, but also for those with reduced quality of life from cholestatic symptoms. Post-transplant care is particularly specific because of the presence of immune-associated diseases, such as inflammatory bowel disease in patients with primary sclerosing cholangitis. Recurrence of the underlying disease in the liver graft is a common long-term complication that can negatively affect graft survival and overall life expectancy. Despite the risk of recurrence, the long-term outcomes of liver transplantation for cholestatic disease are excellent, achieving longer survival compared to other transplant recipients.

BACKGROUND/AIMS: Upper gastrointestinal bleeding (UGIB) is the most common GI condition requiring hospitalization, and can be diagnosed by direct visualization. The present study aimed to evaluate the safety and feasibility of using the PillSense system (EnteraSense Ltd.), a novel diagnostic tool designed for the rapid in vivo detection of UGIB, in human volunteers. METHODS: In the present study, 10 volunteers swallowed a PillSense capsule, followed by 2 servings of an autologous blood preparation. Participants were monitored for capsule passage, overall tolerability of the procedure, and adverse events. RESULTS: The procedure was completed per the protocol established in the present study in 9/10 cases. In 9 of the subjects, after capsule ingestion, the device indicated the absence of blood with sensor output values of 1. After the ingestion of the first blood mixture, the sensor outputs of all devices increased from 2.8 to 4, indicating that each camera detected blood. The sensor output remained within that range after the ingestion of the second mixture; however, in one case, the baseline capsule signal was positive, because of a preexisting condition. The passage of the capsule was verified in all patients, and no adverse events were reported. CONCLUSION: The first trial of the PillSense system in human subjects demonstrated the feasibility, safety, and tolerability of utilizing this product as a novel, noninvasive, and easy-to-use triage tool for the diagnosis of patients suspected of having UGIB.

BACKGROUND: Tumor necrosis factor-alpha (TNF-α) agonists revolutionized therapeutic algorithms in inflammatory bowel disease (IBD) management. However, approximately every third IBD patient does not respond to this therapy in the long term, which delays efficient control of the intestinal inflammation. METHODS: We analyzed the power of serum biomarkers to predict the failure of anti-TNF-α. We collected serum of 38 IBD patients at therapy prescription and 38 weeks later and analyzed them with relation to therapy response (no-, partial-, and full response). We used enzyme-linked immunosorbent assay to quantify 16 biomarkers related to gut barrier (intestinal fatty acid-binding protein, liver fatty acid-binding protein, trefoil factor 3, and interleukin (IL)-33), microbial translocation, immune system regulation (TNF-α, CD14, lipopolysaccharide-binding protein, mannan-binding lectin, IL-18, transforming growth factor-β1 (TGF-β1), osteoprotegerin (OPG), insulin-like growth factor 2 (IGF-2), endocrine-gland-derived vascular endothelial growth factor), and matrix metalloproteinase system (MMP-9, MMP-14, and tissue inhibitors of metalloproteinase-1). RESULTS: We found that future full-responders have different biomarker profiles than non-responders, while partial-responders cannot be distinguished from either group. When future non-responders were compared to responders, their baseline contained significantly more TGF-β1, less CD14, and increased level of MMP-9, and concentration of these factors could predict non-responders with high accuracy (AUC = 0.938). Interestingly, during the 38 weeks, levels of MMP-9 decreased in all patients, irrespective of the outcome, while OPG, IGF-2, and TGF-β1 were higher in non-responders compared to full-responders both at the beginning and the end of the treatment. CONCLUSIONS: The TGF-β1 and CD14 can distinguish non-responders from responders. The changes in biomarker dynamics during the therapy suggest that growth factors (such as OPG, IGF-2, and TGF-β) are not markedly influenced by the treatment and that anti-TNF-α therapy decreases MMP-9 without influencing the treatment outcome.
Inflammatory bowel diseases (IBD) are systemic immune-mediated conditions with predilection for the gastrointestinal tract and include Crohn's disease and ulcerative colitis. Despite the advances in the fields of basic and applied research, the etiopathogenesis remains largely unknown. As a result, only one third of the patients achieve endoscopic remission. A substantial portion of the patients also develop severe clinical complications or neoplasia. The need for novel biomarkers that can enhance diagnostic accuracy, more precisely reflect disease activity, and predict a complicated disease course, thus, remains high. Genomic and transcriptomic studies contributed substantially to our understanding of the immunopathological pathways involved in disease initiation and progression. However, eventual genomic alterations do not necessarily translate into the final clinical picture. Proteomics may represent a missing link between the genome, transcriptome, and phenotypical presentation of the disease. Based on the analysis of a large spectrum of proteins in tissues, it seems to be a promising method for the identification of new biomarkers. This systematic search and review summarize the current state of proteomics in human IBD. It comments on the utility of proteomics in research, describes the basic proteomic techniques, and provides an up-to-date overview of available studies in both adult and pediatric IBD.
