Restrictive diets are unnecessary for colonoscopy: Non-inferiority randomized trial.

Background and study aims In colonoscopy, preparation is often regarded as the most burdensome part of the intervention. Traditionally, specific diets have been recommended, but the evidence to support this policy is insufficient. The aim of this study was to evaluate the impact of the decision not to follow a restrictive diet on bowel preparation and colonoscopy outcomes. Patients and methods This was a multicenter, controlled, non-inferiority randomized trial with FIT-positive screening colonoscopy. The subjects were assigned to follow the current standard (1-day low residue diet [LRD]) or a liberal diet. The allocation was balanced for the risk of inadequate cleansing using the Dik et al. score. All participants received the same instructions for morning colonoscopy preparation. The primary outcome was the rate of adequate preparations as defined by the Boston Bowel Preparation Scale. Secondary outcomes included tolerability and measures of colonoscopy performance and quality. Results A total of 582 subjects were randomized. Of these, 278 who received the liberal diet and 275 who received the 1-day LRD were included in the intent-to-treat analysis. Non-inferiority was demonstrated with adequate preparation rates of 97.8% in the 1-day LRD and 96.4% in the liberal diet group. Tolerability was higher with the liberal diet (94.7% vs. 83.2%). No differences were found with respect to cecal intubation time, aspirated volume, or length of the examination. Global and right colon average adenoma detection rates per colonoscopy were similar. Conclusions The liberal diet was non-inferior to the 1-day LRD, and increased tolerability. Colonoscopy performance and quality were not affected. (NCT05032794).

Diagnostic accuracy of the Oakland score versus haemoglobin for predicting outcomes in lower gastrointestinal bleeding.

BACKGROUND: Acute lower gastrointestinal bleeding (ALGIB) is a common cause of hospitalization. Recent guidelines recommend the use of prognostic scales for risk stratification. However, it remains unclear whether risk scores are more accurate than some simpler prognostic variables. OBJECTIVE: To compare the predictive values of haemoglobin alone and the Oakland score for predicting outcomes in ALGIB patients. DESIGN: Single-centre, retrospective study at a University Hospital. Data were extracted from the hospital's clinical records. The Oakland score was calculated at admission. Study outcomes were defined according to the original article describing the Oakland score: safe discharge (the primary Oakland score outcome), transfusion, rebleeding, readmission, therapeutic intervention and death. Area under the receiver operating characteristics (AUROC) curve and accuracy using haemoglobin and the Oakland score were calculated for each outcome. RESULTS: Two hundred and fifty-eight patients were included. Eighty-four (32.6%) needed transfusion, 50 (19.4%) presented rebleeding, 31 (12.1%) required therapeutic intervention, 20 (7.8%) were readmitted and six (2.3%) died. There were no differences in the AUROC curve values for haemoglobin versus the Oakland score with regard to safe discharge (0.82 (0.77-0.88) vs 0.80 (0.74-0.86), respectively) or to therapeutic intervention and death. Haemoglobin was significantly better for predicting transfusion and rebleeding, and the Oakland score was significantly better for predicting readmission. CONCLUSION: In our study, the Oakland score did not perform better than haemoglobin alone for predicting the outcome of patients with ALGIB. The usefulness of risk scores for predicting outcomes in clinical practice remains uncertain.

La colonoscopia (CS) es una técnica invasiva, fundamental para el estudio del colon. Es un procedimiento seguro y bien tolerado. Sin embargo, en personas de edad avanzada o con fragilidad (PEA/F) aumenta el riesgo de acontecimientos adversos, preparación insuficiente o exploraciones incompletas. El objetivo de este documento de posicionamiento fue consensuar recomendaciones sobre valoración del riesgo, indicaciones y cuidados especiales necesarios para la CS en PEA/F. El documento fue redactado por un grupo de expertos designados por la SCD, la SCGiG y la CAMFiC entre 2020 y 2022. Se consensuaron 8 afirmaciones y recomendaciones, entre ellas: no realizar CS a los pacientes con fragilidad avanzada, indicar CS solo si los beneficios son claramente superiores a los riesgos en fragilidad moderada, no repetir CS en PEA/F que tienen una CS completa previa sin lesiones y no indicar CS de cribado en pacientes con fragilidad moderada o avanzada (AU)

Bowel cleansing effectiveness and safety of 1L PEG + Asc in the real-world setting: Observational, retrospective, multicenter study of over 13000 patients.

Background and study aims Effective bowel cleansing is critical for detecting lesions during colonoscopy, highlighting the importance of bowel preparations. 1L polyethylene glycol (PEG) + ascorbate (Asc) is the only recommended 1L PEG product in Europe and the United States. Its efficacy was demonstrated in large-scale controlled trials and confirmed in smaller-scale real-world studies. However, no large-scale real-world data exist. Patients and methods This observational, retrospective, multicenter study, used outpatient follow-up data from medical records from 10 centers in Spain and two in Portugal. Outpatients aged ≥18 years using 1L PEG + Asc as bowel preparation were included. The main outcome measures were overall adequate colon cleansing (Boston Bowel Preparation Scale [BBPS] score ≥6 with BBPS score ≥2 in each segment) and high-quality cleansing of the right colon (BBPS score=3). Results Data from 13169 eligible patients were included. Overall cleansing success was achieved in 89.3% (95%CI 88.7%-89.8%) and high-quality cleansing in the right colon in 49.3% (95%CI 48.4%-50.2%) of patients. For the overnight split-dose and same-day regimens, overall adequate quality cleansing success rate was 94.7% and 86.7% ( P <0.0001) and high-quality cleansing of the right colon rate was 65.4% and 41.4% ( P <0.0001), respectively. Colonoscopy was completed in 97.3% of patients, with non-completion due to poor preparation in only 0.8%; 2.3% of patients experienced at least one adverse event (AE). Conclusions This large-scale, real-world study demonstrates the effectiveness of 1L PEG + Asc in the total and right colon, with a low percentage of patients with AEs in routine clinical practice.

Patient experience, satisfaction and shared decision-making in colorectal cancer screening: protocol of the mixed-methods study CyDESA.

INTRODUCTION: Colorectal cancer (CRC) screening programmes can reduce incidence and mortality from this condition if adherence to them is high. As patient experience and satisfaction are key factors in determining adherence to screening programmes, they need to be measured. Furthermore, to promote highly patient-centred healthcare, the perception of patients regarding shared decision-making during CRC screening needs to be known. This study aims to assess the experience, satisfaction and participation in decision-making of participants in a CRC screening programme and of patients diagnosed with CRC through this programme in relation to the diagnostic and therapeutic processes of cancer. METHODS AND ANALYSIS: The CyDESA study is a mixed-methods study with a four phase sequential design. In phase 1, we will conduct a systematic review of patient-reported experience measures (PREMs) for patient experience or satisfaction with CRC screening. In case no located PREM can be applied, in phase 2, we will develop a new PREM. We will use the Delphi methodology to reach consensus among experts and patients and will conduct a pilot test of the developed PREM. Phase 3 is a multicentric cross-sectional study based on self-reported questionnaires that will be conducted at three Spanish hospitals (n=843). The objective is to find out about the experience, satisfaction and participation in decision-making of participants in the CRC screening programme who have had a positive screening test result according to their final screening diagnosis: false positives, colorectal polyps or CRC. Phase 4 is a qualitative phenomenological study based on individual interviews. It will explore the experiences of participants in the CRC screening programme and of those diagnosed with CRC. ETHICS AND DISSEMINATION: Ethics approval by the Ethics Committees of Corporació Sanitària Parc Taulí, Hospital de Sant Pau and Parc de Salut Mar. Findings will be published in peer-reviewed journals and presented at conferences. TRIAL REGISTRATION NUMBER: NCT04610086.

Corrigendum to 'A multicenter analysis of the role of prophylactic transfusion of blood products in patients with cirrhosis and esophageal varices undergoing endoscopic band ligation' [JHEP Reports 6 (2021)].

A multicenter analysis of the role of prophylactic transfusion of blood products in patients with cirrhosis and esophageal varices undergoing endoscopic band ligation.

BACKGROUND & AIMS: Prophylactic administration of platelets and fresh frozen plasma (FFP) has been recommended in patients with cirrhosis with low platelets and/or prolonged international normalized ratio (INR) without scientific evidence to support this practice. In this analysis, we evaluated the use of prophylactic administration of blood products in outpatients with cirrhosis undergoing endoscopic band ligation (EBL). METHODS: This is a multicenter retrospective analysis of consecutive EBL procedures in patients with cirrhosis at 4 hospitals in Spain from 01/2010-01/2017. FFP and/or platelet transfusion were given at the discretion of the physician if INR was >1.5 and/or platelet count <50x109/L. Patient demographics, endoscopic findings, bleeding events after EBL, and the use of prophylactic FFP or platelets were recorded. RESULTS: A total of 536 patients underwent 1,472 EBL procedures: 72% male; main etiology HCV and alcohol (72%); median MELD score 11; Child-Pugh A/B/C (59/33/8%). EBL procedures were performed for primary (51%) or secondary (49%) prophylaxis. A median of 2 procedures per patient were performed.1-4 FFP and/or platelets were administered in 41 patients (7.6%). The prophylactic transfusion protocol was followed in 16% and 28% of procedures with high INR and/or low platelets, respectively. Post-EBL bleeding occurred in 26 out of 536 patients (4.8%) and in 33 out of 1,472 procedures (2.2%). Bleeding was due to post-EBL ulcers in 21 patients and due to band dislodgment in 5. In 6 patients, bleeding occurred within 24 hours and in the remaining patients it occurred within 2 weeks after EBL. In those that bled, 7 met criteria for transfusion (2 for FFP and 5 for platelets), of whom only 1 received FFP and 4 received platelets; the remaining 19 patients did not meet criteria for transfusion. There was no association between INR or platelet count and bleeding events. Univariate and multivariate analysis revealed that Child-Pugh and MELD scores were risk factors for post-EBL bleeding. CONCLUSIONS: The incidence of post-EBL bleeding is low and is associated with advanced liver disease. Post-EBL bleeding was not related to baseline INR/platelet count and most outpatients with post-EBL bleeding did not meet criteria for prophylactic transfusion. LAY SUMMARY: Patients with chronic liver disease or cirrhosis and enlarged veins (varices) of the esophagus that can potentially bleed commonly need an endoscopy to treat these varices with elastic rubber bands (endoscopic band ligation). Some patients have low platelet counts or prolonged coagulation tests. This analysis of 4 centers evaluated the use of prophylactic administration of blood products in outpatients with cirrhosis undergoing endoscopic band ligation. The results showed that bleeding after band ligation is uncommon and that if bleeding occurs it does not seem to be related with coagulation tests or the administration of blood products to prevent bleeding after band ligation of esophageal varices.

Comparable quality of bowel preparation with single-day versus three-day low-residue diet: Randomized controlled trial.

BACKGROUND AND AIMS: There is controversy about the length of low-residue diet (LRD) for colonoscopy preparation. The aim of the study was to compare one-day vs. three-day LRD associated to standard laxative treatment for achieving an adequate colonoscopy preparation in average risk subjects with positive fecal immunochemical test undergoing screening colonoscopy. METHODS: A non-inferiority, randomized, controlled, parallel-group clinical trial was performed in the setting of average risk colorectal cancer screening program. Participants were randomized to receive 1-day vs. 3-day LRD in addition to standard polyethilenglicol treatment. Adequacy of preparation was evaluated using the Boston Bowel Preparation Scale (BBPS). Primary outcome was achieving a BBPS ≥ 2 in all colon segments. Analysis was performed for a non-inferiority margin of 5%, a 95% statistical power and one-sided 0.05 significance level. RESULTS: A total of 855 patients were randomized. Adequate bowel preparation was similar between groups: 97.9% of patients in the 1-day LRD group vs 96.9% in the 3-day LRD group achieved the primary outcome (P-value for non-inferiority < 0.001). The percentage of patients with BBPS scores ≥ 8 was superior in the 1-day LRD group (254 vs 221 in the 3-day LRD group, P = 0.032). The 1-day regimen was better tolerated than the 3-day diet. 47.7% (vs 28.7%, P < 0.05) of patients rated the 1-day LRD as very easy to follow. CONCLUSION: The 1-day LRD is non-inferior to 3-day LRD for achieving an adequate colon cleansing before average risk screening colonoscopy and it is better tolerated.

Endoscopic Ultrasound (EUS)-Guided Drainage of a Postsleeve Gastrectomy Subphrenic Collection Using a Lumen Apposition Stent.

Sleeve gastrectomy is currently the most frequently performed bariatric surgery. Postoperative leaks represent the main cause of morbidity in up to 8% of patients with a mortality rate ranging between 0.1 and 5%. However, management of these leaks remains controversial. We report the case of a patient presenting with sepsis 2 weeks after surgery. A subphrenic collection and a leak were found on CT. Despite medical treatment, the patient did not show clinical improvement. Hence, we considered a transgastric endosonographic-guided drainage of the collection using an electrocautery-enhanced lumen-apposing metal stent (LAMS). The procedure underwent uneventfully, and the patient status improved rapidly. Two weeks later, the stent was withdrawn. A follow-up endoscopy 6 weeks later showed closure of the gastric wall defect.

Hepatotoxicidad de perfil mixto por apixaban / Apixaban-induced liver injury

Los nuevos anticoagulantes orales, entre ellos apixaban, se usan cada vez más. Presentamos el caso de una paciente de 85 años a la que se diagnosticó de hepatitis tóxica por apixaban de perfil mixto. A la paciente se le realizó el estudio etiológico, que fue negativo excepto por presentar anticuerpos antimúsculo liso positivos, por lo que se le realizó una biopsia hepática que descartó la hepatitis autoinmune y que presentó hallazgos que pueden orientar a una causa tóxica. Con el cálculo de la escala de causalidad CIOMS/RUCAM se obtuvo una puntuación de 7 (probable) y tras la retirada del fármaco se observó mejoría del daño hepático. Un metaanálisis muestra que no hay un riesgo aumentado de hepatotoxicidad con el uso de apixaban y en los estudios de registro no se recogen casos para la ficha técnica. A pesar de ello, en la base de datos europea de farmacovigilancia (EudraVigilance) se recogen más de 120 casos. En definitiva, se debe considerar apixaban como un fármaco con potencial de hepatotoxicidad

The use of new oral anticoagulants such as apixaban is increasing. We present the case of an 85-year-old patient who was diagnosed with mixed profile toxic hepatitis due to apixaban use. An etiological study was negative, except for anti-smooth muscle antibodies, and a liver biopsy ruled out autoimmune hepatitis. The patient was assigned a score of 7 on the CIOMS/RUCAM scale, indicating a probable causality. The liver injury improved after the withdrawal of apixaban. A previous meta-analysis reported that the risk of hepatotoxicity does not increase with the use of apixaban, nor were any cases reported in registry studies. Nonetheless, more than 120 possible cases currently appear in the European pharmacovigilance database (EudraVigilance). We suggest that apixaban should be considered as a possible cause of liver injury

Eficacia diagnóstica de la sonda nasogástrica y de la relación nitrógeno ureico en sangre (BUN)/creatinina para distinguir el origen alto o bajo de la hemorragia digestiva / Diagnostic utility of nasogastric tube aspiration and the ratio of blood urea nitrogen to creatinine for distinguishing upper and lower gastrointestinal tract bleeding

Objetivo. La guía clínica para el tratamiento de la hemorragia digestiva (HD) baja del American College of Gastroenterology publicada en el año 2016 defiende la valoración del aspirado por sonda nasogástrica (SNG) y la evaluación de la relación nitrógeno ureico en sangre (BUN)/creatinina para diferenciar el origen alto o bajo de la HD. Sin embargo, la recomendación de ambas se realiza con un grado de evidencia bajo. El objetivo de este estudio es evaluar la eficacia diagnóstica del aspirado por SNG y la relación BUN/creatinina para diferenciar el origen de una HD. Métodos. Se realizó una revisión sistemática de la literatura para identificar los estudios que evalúan la precisión diagnóstica de la relación BUN/creatinina y el aspirado por SNG en pacientes con HD sin hematemesis. Resultados. Ambos métodos tienen una baja sensibilidad para detectar un sangrado digestivo alto. Tanto el aspirado hemático como la relación BUN/creatinina elevada aumentan significativamente la probabilidad de una HD alta. La razón de verosimilitud positiva varía de 2 a 11. Sin embargo, la sensibilidad de ambas pruebas para la HD alta fue muy baja (razón de verosimilitud negativa alrededor de 0,6). Conclusiones. Un resultado negativo en cualquiera de las dos pruebas proporciona poca información y no permite descartar con seguridad una HD alta. Por ello, no se puede recomendar el uso del aspirado por SNG para descartar un origen alto de la HD. Si existe duda diagnóstica es necesario la realización de una endoscopia digestiva alta

Background and objective. The American College of Gastroenterology's 2016 clinical guidelines for treating lower gastrointestinal (GI) tract bleeding recommends evaluating of nasogastric tube aspiration and the ratio of blood urea nitrogen (BUN) to creatinine to differentiate upper from lower GI bleeds. However, the evidence base to support recommending these 2 diagnostic variables is low. This study aimed to evaluate the diagnostic utility of nasogastric tube aspiration and the BUN-to-creatinine ratio for distinguishing between upper and lower GI bleeding. Methods. We conducted a systematic review of the literature to find studies reporting the diagnostic precision of the BUN-to-creatinine ratio and nasogastric aspiration in patients with GI bleeding without hematemesis. Results. The sensitivity of both methods is low for detecting upper GI bleeding. Both blood in the aspirate and an elevated BUN-to-creatinine ratio significantly increase the probability of finding an upper GI source. The positive likelihood ratio varies from positive 2 to 11. However, the sensitivity of both tests for a diagnosis of upper GI bleeding is very low (negative likelihood ratio of 0.6). Conclusions. A negative result on either of the 2 diagnostic tests provides little useful information and does not firmly rule out an upper GI bleed. Nasogastric tube aspiration cannot be recommended for distinguishing between upper and lower GI bleeding. If the diagnosis is in doubt, endoscopic exploration of the upper GI tract is necessary

Analysis of survival and prognostic factors in treatment of hepatocellular carcinoma in Spanish patients with drug-eluting bead transarterial chemoembolization.

BACKGROUND AND AIM: Drug-eluting bead transarterial chemoembolization (DEB-TACE) improves the survival of patients with hepatocellular carcinoma (HCC), intermediate stage [i.e. Barcelona Clinic Liver Cancer-B (BCLC-B)]. The aim of our study was to analyse the overall survival (OS) and prognostic factors of patients with HCC treated with DEB-TACE. PATIENTS AND METHODS: Patients' clinical course was recorded from January 2005 to July 2014. The median OS was obtained by the Kaplan-Meier method and compared using the log-rank test. The prognosis factors associated with OS were determined by a multivariate Cox regression analysis and the accuracy of the OS prediction was determined by calculation of the assessment for retreatment with TACE score (ART score). RESULTS: A cohort of 147 consecutive patients treated with DEB-TACE was included. Median age of the patients was 73.4 years. Overall, 68.7% were men, and all had cirrhosis, with 68.8% being hepatisis C virus positive. Moreover, 35.2% were staged as BCLC-A and 60.2% as BCLC-B. After a median follow-up of 19.2 months, 29.3% were alive, 4.3% needed treatment with sorafenib and 56.1% underwent DEB-TACE retreatment. Median OS was 22.8 [95% confidence interval (CI)=19.6-25.9]. After censoring for ascites and more than one nodule, OS was 23.87 (95% CI =20.72-27.01) and 26.89 (95% CI =21.00-32.78), respectively. The risk of death decreased by 22.3% with the number of DEB-TACE sessions (hazard ratio=0.777) and increased by 25.9% with higher Child-Pugh score (hazard ratio=1.259). Overall, 61.2% of the cohort had an ART score between 0 and 1.5. There were no statistical differences in OS between cohort groups with ART of 0-1.5 and at least 2.5. CONCLUSION: The results validate the efficacy and safety of DEB-TACE in patients with HCC and the importance of some prognostic factors for patient survival.

Idiopathic portal hypertension with regard to thiopurine treatment.

Idiopathic portal hypertension (IPH) is an infrequent adverse reaction to the use of thiopurines that tends to be overlooked. Herein, we present a patient with ileocolic Crohn's disease treated with azathioprine who presented ascites, esophageal varices and splenomegaly without any signs of liver cirrhosis. A portal hemodynamics study revealed a normal portosystemic gradient compatible with presinusoidal portal hypertension. Finally, IPH was diagnosed after a liver biopsy. IPH secondary to thiopurines is due to a 6-thioguanine nucleotide (6-TGN)-dependent reaction and occurs predominantly between three months and three years after the start of treatment. The onset is usually insidious and thrombocytopenia is the first manifestation. The definitive diagnosis is obtained by liver biopsy.

Factores pronósticos de mortalidad en la cirrosis hepática tras un primer episodio de peritonitis bacteriana espontánea. Estudio multicéntrico / Prognostic factors of liver cirrhosis mortality after a first episode of spontaneous bacterial peritonitis. A multicenter study

Introducción: la peritonitis bacteriana espontánea es una complicación infecciosa con impacto negativo sobre la supervivencia de los pacientes con cirrosis. Objetivo: analizar la supervivencia a corto y largo plazo después de un primer episodio de peritonitis bacteriana espontánea y los factores pronósticos asociados. Material y métodos: estudio multicéntrico retrospectivo que incluyó a los pacientes ingresados por peritonitis bacteriana espontánea entre 2008 y 2013. Las variables independientes relacionadas con la mortalidad se analizaron mediante regresión logística. Se analizó el poder pronóstico de los índices Child Pugh, MELD y Charlson mediante curva de ROC. Resultados: fueron incluidos 159 pacientes. El 72% fueron hombres con una edad media de 63,5 años y con una puntuación MELD de 19 (DE ± 9,5). La mortalidad a los 30 días, 90 días, al año y a los dos años fue del 21%, 31%, 55% y 69%, respectivamente. La encefalopatía hepática (p = 0,008; OR 3,5; IC 95% 1,4-8,8) y la función renal (p = 0,026; OR 2,7; IC 95% 1,13-16,7) fueron factores independientes de mortalidad a corto y largo plazo. El MELD fue un buen indicador de supervivencia a corto y largo plazo (área bajo la curva [AUC] 0,7: IC 95% 1,02-1,4). El índice de Charlson se relacionó con la mortalidad a largo plazo (AUC 0,68: IC 95% 0,6-0,77). Conclusiones: en la peritonitis bacteriana espontánea la mortalidad a corto y largo plazo sigue siendo elevada. Los principales factores pronósticos de mortalidad son el deterioro de la función hepática y renal. El MELD y el índice de Charlson son unos buenos indicadores de supervivencia (AU)

Introduction: Spontaneous bacterial peritonitis is an infectious complication with a negative impact on survival of patients with cirrhosis. Objective: To analyze the short- and long-term survival after a first episode of bacterial peritonitis and the associated prognostic factors. Patients and methods: This was a retrospective, multicenter study of patients admitted to hospital for spontaneous bacterial peritonitis between 2008 and 2013. Independent variables related to mortality were analyzed by logistic regression. The prognostic power of the Child Pugh Score, the Model for End-Stage Liver Disease (MELD) and the Charlson index was analyzed by ROC curve. Results: A total of 159 patients were enrolled, 72% were males with a mean age of 63.5 years and a mean MELD score of 19 (SD ± 9.5). Mortality at 30 and 90 days and one and two years was 21%, 31%, 55% and 69%, respectively. Hepatic encephalopathy (p = 0.008, OR 3.5, 95% CI 1.4-8.8) and kidney function (p = 0.026, OR 2.7, 95% CI 1.13-16.7) were independent factors for short- and long-term mortality. MELD was a good marker of short- and long-term survival (area under the curve [AUC] 0.7: 95% CI 1.02-1.4). The Charlson index was related to long-term mortality (AUC 0.68: 95% CI 0.6-0.77). Conclusions: Short- and long-term mortality of spontaneous bacterial peritonitis is still high. The main prognostic factors for mortality are impairment of liver and kidney function. MELD and the Charlson index are good markers of survival (AU)
