RESUMEN
Background and study aims There is still a lack of evidence-based recommendations concerning endoscopic bougienage in benign esophageal strictures. Our study aimed to assess the relevance of the time interval between endoscopic dilation (ED) sessions with regard to endoscopic and clinical response. Patients and methods We performed a retrospective study including patients treated with endoscopic bougienage for a benign esophageal stricture in two German centers. Primary endpoint was the number of ED until freedom from dysphagia was achieved. Secondary endpoints were analyses on reaching a diameter of 15 mm and on achieving clinical freedom from symptoms. Results Between April 2014 and March 2020, bougienage was used as the primary treatment for benign esophageal strictures in 238 patients (194 patients in Center 1; 44 patients in Center 2). Both centers differed in their endoscopic bougienage regime: Center 1 was characterized by a higher frequency of interventions compared to Center 2 (median: 2 days [range 1-28] vs. 10 days [range 1-41]; P <0.001). Clinical response was achieved significantly earlier using the high-frequency regimen in all patients except for those with post-radiogen strictures, who clinically benefited from a low-frequency ED program. Accordingly, patients receiving higher-frequency ED reached a significantly larger post-dilation diameter and considerably larger diameter differences. Conclusions The results of our study demonstrate that a treatment concept consisting of higher-frequency bougienages seems to be more effective in treating most types of esophageal stricture. Radiogenic strictures were the only types of stenoses that benefited from a lower frequency ED program.
RESUMEN
Malignancies can cause severe stenosis of the biliary tract and therefore predispose a patient to bacterial cholangitis. Upon endoscopic drainage, antibiotic therapy (AT) is performed according to individual clinical judgement, as the optimal duration of AT is unclear to date, especially in the case of multidrug-resistant organisms (MDROs). In a case-based retrospective study, patients with malignant biliary strictures and acute cholangitis were included upon endoscopic retrograde cholangiography (ERC). The outcome of cases treated with short AT (≤6 days) was compared to that of long AT (≥7 days). Recurrent cholangitis (RC) before scheduled stent exchange was the primary end point. In total, 124 patients were included, with 183 cases of proven cholangitis in total. The overall median duration of AT was 7 days (range 1-20), with 74 cases (40%) receiving short AT and 109 (60%) receiving long AT. Short AT was not an independent risk factor for RC (HR = 0.66, p > 0.2), while colonization with MDROs was associated with a higher risk of RC (HR = 2.21, p = 0.005). Placement of a metal stent was associated with minor risk of RC (HR = 0.4, p = 0.038). In conclusion, short AT is possible in selected patients with non-severe cholangitis and malignant biliary strictures. Scheduled screening for MDROs is recommended and placement of a metal stent should be performed if possible.
RESUMEN
Glucocorticoid excess is a known risk factor for non-alcoholic fatty liver disease (NAFLD). Our objective was to analyse the impact of glucocorticoid replacement therapy on the development of NAFLD and NAFLD-related fibrosis and, therefore, on cardiovascular as well as hepatic morbidity in patients with adrenal insufficiency. Two hundred and fifteen individuals with primary (n = 111) or secondary (n = 104) adrenal insufficiency were investigated for hepatic steatosis and fibrosis using the fatty liver index (FLI), NAFLD fibrosis score (NAFLD-FS), Fibrosis-4 Index (FiB-4) plus sonographic transient elastography. Results were correlated with glucocorticoid doses and cardiometabolic risk parameters. The median dose of hydrocortisone equivalent was 20 mg daily, with a median therapy duration of 15 years. The presence and grade of hepatic steatosis and fibrosis were significantly correlated with cardiometabolic risk factors. We could not find any significant correlations between single, daily or cumulative doses of glucocorticoids and the grade of liver steatosis, nor with fibrosis measured via validated sonographic techniques. In patients with adrenal insufficiency, glucocorticoid replacement within a physiological range of 15-25 mg hydrocortisone equivalent per day does not appear to pose an additional risk for the development of NAFLD, subsequent liver fibrosis, or the cardiovascular morbidity associated with these conditions.
RESUMEN
BACKGROUND: Non-anastomotic biliary strictures (NAS) are a common cause of morbidity and mortality after liver transplantation. METHODS: All patients with NAS from 2008 to 2016 were retrospectively analyzed. The success rate and overall mortality of an ERCP-based stent program (EBSP) were the primary outcomes. RESULTS: A total of 40 (13.9%) patients with NAS were identified, of which 35 patients were further treated in an EBSP. Furthermore, 16 (46%) patients terminated EBSP successfully, and nine (26%) patients died during the program. All deaths were caused by cholangitis. Of those, one (11%) patient had an extrahepatic stricture, while the other eight patients had either intrahepatic (3, 33%) or combined extra- and intrahepatic strictures (5, 56%). Risk factors of overall mortality were age (p = 0.03), bilirubin (p < 0.0001), alanine transaminase (p = 0.006), and aspartate transaminase (p = 0.0003). The median duration of the stent program was 34 months (ITBL: 36 months; IBL: 10 months), and procedural complications were rare. CONCLUSIONS: EBSP is safe, but lengthy and successful in only about half the patients. Intrahepatic strictures were associated with an increased risk of cholangitis.
RESUMEN
BACKGROUND AND STUDY AIM: The incidence of wound infections after percutaneous endoscopic gastrostomy (PEG) varies widely in recent studies. The present study systematically investigates the underlying risk factors for the development of wound infections in a large cohort of patients over a long-term follow-up period. PATIENTS AND METHODS: A retrospective cohort study of patients undergoing PEG insertion using either the pull or push technique was conducted and patients followed up for 3 years. Tube-related wound infections were identified, and pathogens regularly cultured from wound swabs. Adjusted analysis was performed via univariate and multivariate logistic regression analysis. RESULTS: 616 patients were included in this study. A total of 25% percent of patients developed wound infections upon PEG tube insertion and 6.5% showed recurrent infections. Nicotine abuse (p = 0.01), previous ischemic stroke (p = 0.01) and head and neck cancer (p < 0.001) showed an increased risk for wound infection after PEG placement. Moreover, radio-chemotherapy was associated with the occurrence of wound infections (p < 0.001). Infection rates were similar between pull and push cohorts. The most common bacterial pathogen detected was Enterobacterales (19.2%). Staphylococcus aureus, Pseudomonas aeruginosa and enterococci were frequently detected in recurrent infection (14.2%, 11.4% and 9.6%, respectively). Antibiotic prophylaxis showed no effect on infection rates. CONCLUSIONS: Wound infections after PEG placement are common and occasionally occur as recurrent infections. There is potential for improvement in everyday clinical practice, particularly regarding antibiotic prophylaxis in accordance with guidelines.
RESUMEN
Fluorescence confocal microscopy (FCM) is a rapidly evolving tool that provides real-time virtual HE images of native tissue. Data about the potential of FCM as an alternative to frozen sections for the evaluation of donor liver specimens are lacking so far. The aim of the current study was to determine the value of FCM in liver specimens according to the criteria of the German Society for Organ Procurement. In this prospective study, conventional histology and FCM scans of 50 liver specimens (60% liver biopsies, 26% surgical specimens, and 14% donor samples) were evaluated according to the German Society for Organ Procurement. A comparison of FCM scans and conventional frozen sections revealed almost perfect levels of agreement for cholangitis (κ = 0.877), fibrosis (κ = 0.843), and malignancy (κ = 0.815). Substantial levels of agreement could be obtained for macrovesicular steatosis (κ = 0.775), inflammation (κ = 0.763), necrosis (κ = 0.643), and steatohepatitis (κ = 0.643). Levels of agreement were moderate for microvesicular steatosis (κ = 0.563). The strength of agreement between frozen sections and FCM was superior to the comparison of conventional HE and FCM imaging. We introduce FCM as a potential alternative to the frozen section that may represent a novel approach to liver transplant pathology where timely feedback is crucial and the deployment of human resources is becoming increasingly difficult.

BACKGROUND/AIMS: Endoscopic therapy for neoplastic Barrett's esophagus (BE) has become the standard of care over the past two decades. In clinical practice, we regularly encounter patients who fail to achieve complete squamous epithelialization of the esophagus. Although the therapeutic strategies in the individual stages of BE, dysplasia, and esophageal adenocarcinoma are well studied and largely standardized, the problem of inadequate healing after endoscopic therapy is only marginally considered. This study aimed to shed light on the variables influencing inadequate wound healing after endoscopic therapy and the effect of bile acid sequestrants (BAS) on healing. METHODS: Retrospective analysis of endoscopically treated neoplastic BE in a single referral center. RESULTS: In 12.1% out of 627 patients, insufficient healing was present 8 to 12 weeks after previous endoscopic therapy. The average follow-up duration was 38.8±18.4 months. Complete healing was achieved in 13 patients already after intensifying proton pump inhibitor therapy. Out of 48 patients under BAS, 29 patients (60.4%) showed complete healing. An additional eight patients (16.7%) improved, but only partial healing was achieved. Eleven (22.9%) patients showed no response to BAS augmented therapy. CONCLUSION: In cases of insufficient healing even under exhaustion of proton pump inhibitors, treatment with BAS can be an option as an ultimate healing attempt.

OBJECTIVES: Stenosis of the biliary anastomosis predisposes liver graft recipients to bacterial cholangitis. Antibiotic therapy (AT) is performed according to individual clinical judgment, but duration of AT remains unclear. METHODS: All liver graft recipients with acute cholangitis according to the Tokyo criteria grade 1 and 2 after endoscopic retrograde cholangiography (ERC) were included. Outcome of patients treated with short AT (<7 days) was compared to long AT (>6 days). Recurrent cholangitis (RC) within 28 days was the primary end point. RESULTS: In total, 30 patients were included with a median of 313 (range 34-9849) days after liver transplantation until first proven cholangitis. Among 62 cases in total, 51/62 (82%) were graded as Tokyo-1 and 11/62 (18%) as Tokyo-2. Overall median duration of AT was 6 days (1-14) with 36 cases (58%) receiving short AT and 26 (42%) receiving long AT. RC was observed in 10 (16%) cases, without significant difference in occurrence of RC in short versus long AT cases. CRP and bilirubin were significantly higher in patients with long AT, while low serum albumin and low platelets were associated with risk of RC. CONCLUSION: A shorter antibiotic course than 7 days shows good results in selected, ERC-treated patients for post-transplantation biliary strictures.

OBJECTIVES: The diagnostic value of liver biopsy in patients with acute liver injury or acute liver failure (ALI/ALF) was investigated. METHODS: Data from the initial event and follow-up visits were retrospectively analyzed in all patients with a liver biopsy during ALI/ALF from January 2010 to May 2020 at the University Hospital Frankfurt, Germany. RESULTS: The cohort comprised 66 patients. Post-biopsy hemorrhage occurred in 2 of 66 but was self-limited. In five patients suspected liver involvement by a systemic extrahepatic disease was confirmed and excluded in eight patients. In 4 of 66 patients, the etiology of ALI/ALF remained unknown. Liver biopsy hinted at the etiology of ALI/ALF in 2 of 6 patients with rare diagnoses (hemophagocytic lymphohistiocytosis: 2 of 66; ischemic liver injury: 1 of 66, ALI/ALF due to a systemic infection: 3 of 66). In 31 of 34 patients with drug-induced liver injury (DILI), histopathology suggested DILI; in further 2 patients, DILI was among the differential diagnoses. However, DILI was also the histopathologically preferred diagnosis in 12 of 15 patients with autoimmune hepatitis (AIH). Only in 3 of 15 patients, histopathology was considered compatible with AIH. Serum immunoglobulin G (IgG) and autoantibodies during ALI/ALF were higher in patients with AIH than with DILI. Patients with AIH did not show a more pronounced biochemical response to corticosteroids in the first 10 days of treatment than patients with DILI. CONCLUSIONS: Liver biopsy is indispensable when liver involvement by an extrahepatic disease is suspected. To distinguish AIH from DILI in ALI/ALF, serum IgG, and autoantibodies seem more helpful than liver biopsy; long-term follow-up is needed in these patients.

BACKGROUND AND AIM: The main disadvantage of plastic stents is the high rate of stent occlusion. The usual replacement interval of biliary plastic stents is 3 months. This study aimed to investigate if a shorter interval of 6-8 weeks impacts the median premature exchange rate (mPER) in benign and malignant biliary strictures. METHODS: All cases with endoscopic retrograde cholangiopancreatography (ERCP) and plastic stent placement were retrospectively analyzed since establishing an elective replacement interval of every 6-8 weeks at our institution and mPER was determined. RESULTS: A total of 3979 ERCPs (1199 patients) were analyzed, including 1262 (31.7%) malignant and 2717 (68.3%) benign cases, respectively. The median stent patency (mSP) was 41 days (range 14-120) for scheduled stent exchanges, whereas it was 17 days (1-75) for prematurely exchanged stents. The mPER was significantly higher for malignant (28.1%, 35-50%) compared with benign strictures (15.2%, 10-28%), P < 0.0001, respectively. mSP was significantly shorter in cases with only one stent (34 days [1-87] vs 41 days [1-120]) and in cases with only a 7-Fr stent (28 days [2-79]) compared with a larger stent (34 days [1-87], P = 0.001). Correspondingly, mPER was significantly higher in cases with only one stent (23% vs 16.2%, P < 0.0001) and only a 7-Fr stent (31.3% vs 22.4%, P = 0.03). CONCLUSION: A shorter replacement interval does not seem to lead to a clinically meaningful reduction of mPER in benign and malignant strictures. Large stents and multiple stenting should be favored as possible.

BACKGROUND: The association between type 2 diabetes mellitus (T2DM) and advanced stages of non-alcoholic fatty liver disease is well known. Some studies indicate a relevant prevalence also in type 1 diabetes mellitus (T1DM), but so far there is only limited data. OBJECTIVE: To determine the prevalence of non-alcoholic fatty liver disease (NAFLD)-related liver fibrosis in individuals with T1DM and compare to those with type 2 diabetes. METHODS: Diabetic patients from a single diabetes care centre were screened for liver fibrosis by sonographic shear wave elastography (SWE). In addition, all patients received laboratory evaluation including non-alcoholic fatty liver fibrosis score and Fibrosis-4 Index. RESULTS: Three hundred and forty patients were included in the study, of these, 310 received SWE. Overall 254 patients (93 with type 1 and 161 with type 2 diabetes) had reliable measurements and were included in the final analysis. In patients with type 1 diabetes, the prevalence of NAFLD-related liver fibrosis was 16-21%, depending on the method of detection. Significant liver fibrosis was observed in 30-46% of patients with type 2 diabetes. CONCLUSIONS: Our data revealed an unexpectedly high prevalence of NAFLD-related liver fibrosis in patients with type 1 diabetes. To our knowledge, this is one of the first studies using SWE to diagnose advanced NAFLD in type 1 diabetes in a non-preselected cohort. Considering the findings of our study, regular screening for hepatic complications must be recommended for all diabetic patients, even for those with type 1 diabetes.

BACKGROUND AND AIMS: Direct endoscopic necrosectomy (DEN) of walled-off pancreatic necrosis (WOPN) lacks dedicated instruments and requires repetitive and cumbersome procedures. This study evaluated the safety and efficacy of a new powered endoscopic debridement (PED) system designed to simultaneously resect and remove solid debris within WOPN. METHODS: This was a single-arm, prospective, multicenter, international device trial conducted from November 2018 to August 2019 at 10 sites. Patients with WOPN ≥6 cm and ≤22 cm and with >30% solid debris were enrolled. The primary endpoint was safety through 21 days after the last DEN procedure. Efficacy outcomes included clearance of necrosis, procedural time, adequacy of debridement, number of procedures until resolution, hospital stay duration, and quality of life. RESULTS: Thirty patients (mean age, 55 years; 60% men) underwent DEN with no device-related adverse events. Of 30 patients, 15 (50%) achieved complete debridement in 1 session and 20 (67%) achieved complete debridement within 2 or fewer sessions. A median of 1.5 interventions (range, 1-7) were required. Median hospital stay was 10 days (interquartile range, 22). There was an overall reduction of 91% in percent necrosis within WOPN from baseline to follow-up and 85% in collection volume. Baseline WOPN volume was positively correlated with the total number of interventions (ρ = .363, P = .049). CONCLUSIONS: The new PED system seems to be a safe and effective treatment tool for WOPN, resulting in fewer interventions and lower hospital duration when compared with published data on using conventional instruments. Randomized controlled trials comparing the PED system with conventional DEN are needed. (Clinical trial registration number: NCT03694210.).

OBJECTIVE: Liver stiffness measurement (LSM) is a tool used to screen for significant fibrosis and portal hypertension. The aim of this retrospective multicentre study was to develop an easy tool using LSM for clinical outcomes in advanced chronic liver disease (ACLD) patients. DESIGN: This international multicentre cohort study included a derivation ACLD patient cohort with valid two-dimensional shear wave elastography (2D-SWE) results. Clinical and laboratory parameters at baseline and during follow-up were recorded. LSM by transient elastography (TE) was also recorded if available. The primary outcome was overall mortality. The secondary outcome was the development of first/further decompensation. RESULTS: After screening 2148 patients (16 centres), 1827 patients (55 years, 62.4% men) were included in the 2D-SWE cohort, with median liver SWE (L-SWE) 11.8 kPa and a model for end stage liver disease (MELD) score of 8. Combination of MELD score and L-SWE predict independently of mortality (AUC 0.8). L-SWE cut-off at ≥20 kPa combined with MELD ≥10 could stratify the risk of mortality and first/further decompensation in ACLD patients. The 2-year mortality and decompensation rates were 36.9% and 61.8%, respectively, in the 305 (18.3%) high-risk patients (with L-SWE ≥20 kPa and MELD ≥10), while in the 944 (56.6%) low-risk patients, these were 1.1% and 3.5%, respectively. Importantly, this M10LS20 algorithm was validated by TE-based LSM and in an additional cohort of 119 patients with valid point shear SWE-LSM. CONCLUSION: The M10LS20 algorithm allows risk stratification of patients with ACLD. Patients with L-SWE ≥20 kPa and MELD ≥10 should be followed closely and receive intensified care, while patients with low risk may be managed at longer intervals.

PURPOSE: Hepatic hydrothorax (HH) is defined as transudate in the pleural cavity in patients with decompensated liver cirrhosis (DC) without concomitant cardiopulmonary or pleural disease. It is associated with high short-term mortality. HH can evolve via translocation through diaphragmatic gaps. The aim of this study was to evaluate the feasibility and safety of injecting ultrasound contrast medium into the peritoneal cavity to detect HH. MATERIALS AND METHODS: This study included patients with concomitant ascites and pleural effusion who were admitted to our hospital between March 2009 and February 2019. A peritoneal catheter was inserted and ultrasound contrast medium was injected into the peritoneal cavity. In parallel, the peritoneal and pleural cavities were monitored for up to 10 minutes. RESULTS: Overall, 43 patients were included. The median age was 60 years and the majority of patients were male (nâ=â32, 74â%). Most patients presented with right-sided pleural effusion (nâ=â32, 74â%), 3 (7â%) patients with left-sided and 8 (19â%) patients had bilateral pleural effusion. In 12 (28â%) patients ascites puncture was not safe due to low volume ascites. Thus, the procedure could be performed in 31 (72â%) patients. No adverse events occurred. In 16 of 31 (52â%) patients we could visualize a trans-diaphragmic flow of microbubbles. The median time until transition was 120 seconds. CONCLUSION: Our clinical real-world experience supports the safety and feasibility of intraperitoneal ultrasound contrast medium application to detect HH in patients with DC, as a non-radioactive real-time visualization of HH. Our study comprises the largest cohort and longest experience using this method to date.

Long-term effects on cirrhosis and portal hypertension of direct antiviral agent (DAA)-based eradication of hepatitis C virus (HCV) are still under debate. We analysed dynamics of liver and spleen elastography to assess potential regression of cirrhosis and portal hypertension 3 years post-treatment. Fifty-four patients with HCV-associated cirrhosis and DAA-induced SVR were included. Liver and spleen stiffness were measured at baseline (BL), end of treatment (EOT), 24 weeks after EOT (FU24) and 1, 2 and 3 (FU144) years post-treatment by transient liver elastography (L-TE) and point shear wave elastography (pSWE) using acoustic radiation force impulse (ARFI) of the liver (L-ARFI) and spleen (S-ARFI). Biochemical, virological and clinical data were also obtained. Liver stiffness assessed by L-TE decreased between BL [median (range), 32.5(9.1-75) kPa] and EOT [21.3(6.7-73.5) kPa; p < .0001] and EOT and FU144 [16(4.1-75) kPa; p = .006]. L-ARFI values improved between EOT [2.5(1.2-4.1) m/s] and FU144 [1.7(0.9-4.1) m/s; p = .001], while spleen stiffness remained unchanged. Overall, L-TE improved in 38 of 54 (70.4%) patients at EOT and 29 of 38 (76.3%) declined further until FU144, whereas L-ARFI values decreased in 30/54 (55.6%) patients at EOT and continued to decrease in 28/30 (93.3%) patients at FU144. Low bilirubin and high albumin levels at BL were associated with improved L-ARFI values (p = .048) at EOT or regression of cirrhosis (<12.5 kPa) by L-TE at FU144 (p = .005), respectively. Liver stiffness, but not spleen stiffness, continued to decline in a considerable proportion of patients with advanced liver disease after HCV eradication.

INTRODUCTION: Aortoesophageal fistula (AEF) is a life-threatening complication associated with endovascular aortic repair (EVAR) and occurs mostly in patients who undergo thoracic EVAR (TEVAR). To date, surgical treatment of AEF has been considered the most promising therapeutic approach. New endoscopic techniques could contribute to the therapy of AEF. The aim of this study was to analyze the outcome after endoscopic treatment of EVAR-associated AEF. METHODS: All patients who received endoscopic diagnostics and/or therapy for AEF after EVAR/TEVAR in our center between 2010 and 2019 were evaluated. RESULTS: Seven suitable patients were included. Six of them had undergone TEVAR and 1 had EVAR. Fistula occurred at an average of 307 days (range 21-2,774 days) post-EVAR. Endoscopic treatment was performed on 4 patients by using an over-the-scope clip (OTSC®). However, fistula recurred in all patients who were initially treated endoscopically. They were then treated either by sequential application of further OTSCs® or by implantation of a fully coated, self-expanding metal stent. One of these patients underwent a partial esophageal resection in a subsequent treatment approach. All patients died during the observational period, 5 as a direct consequence of the AEF/aortoduodenal fistula and 2 due to comorbidities. The median survival time after fistula occurrence was 120 days (range 5-823 days). CONCLUSION: Endoscopic treatment of AEF with OTSC® should be considered as a possible interim solution, especially in patients with severe comorbidities. However, surgical remediation still appears to be the only procedure with intermediate to long-term therapeutic success.
