ABSTRACT
Motorized spiral enteroscopy (MSE) enhances small bowel exploration, but the optimal target population for this technique is unknown. We aimed to identify the target population for MSE by evaluating its efficacy and safety, as well as detecting predictors of efficacy. A prospective multicenter observational study was conducted at 9 tertiary hospitals in Spain, enrolling patients between June 2020-2022. Analyzed data included demographics, indications for the procedure, exploration time, depth of maximum insertion (DMI), technical success, diagnostic yield, interventional yield, and adverse events (AE) up to 14 days from enteroscopy. Patients with prior gastrointestinal surgery, unsuccessful balloon enteroscopy and small bowel strictures were analyzed. A total of 326 enteroscopies (66.6% oral route) were performed in 294 patients (55.1% males, 65 years ± 21). Prior abdominal surgery was present in 50% of procedures (13.5% gastrointestinal surgery). Lower DMI (162 vs 275 cm, p = 0.037) and diagnostic yield (47.7 vs 67.5%, p = 0.016) were observed in patients with prior gastrointestinal surgery. MSE showed 92.2% technical success and 56.9% diagnostic yield after unsuccessful balloon enteroscopy (n = 51). In suspected small bowel strictures (n = 49), the finding was confirmed in 23 procedures (46.9%). The total AE rate was 10.7% (1.8% classified as major events) with no differences related to prior gastrointestinal/abdominal surgery, unsuccessful enteroscopy, or suspected small bowel strictures. The study demonstrates that MSE has a lower diagnostic yield and DMI in patients with prior gastrointestinal surgery but is feasible after unsuccessful balloon-enteroscopy and in suspected small bowel strictures without safety concerns.

BACKGROUND AND STUDY AIMS: Our aim was to determine the impact of the SARS-CoV-2 pandemic on the diagnosis and prognosis of colorectal cancer (CRC). PATIENTS AND METHODS: This prospective cohort study included individuals diagnosed with CRC between March 13, 2019 and June 20, 2021 across 21 Spanish hospitals. Two time periods were compared: prepandemic (from March 13, 2019 to March 13, 2020) and pandemic (from March 14, 2020 to June 20, 2021, lockdown period and 1 year after lockdown). RESULTS: We observed a 46.9% decrease in the number of CRC diagnoses (95% confidence interval (CI): 45.1%-48.7%) during the lockdown and 29.7% decrease (95% CI: 28.1%-31.4%) in the year after the lockdown. The proportion of patients diagnosed at stage I significantly decreased during the pandemic (21.7% vs. 19.0%; p = 0.025). Centers that applied universal preprocedure SARS-CoV-2 PCR testing experienced a higher reduction in the number of colonoscopies performed during the pandemic post-lockdown (34.0% reduction; 95% CI: 33.6%-34.4% vs. 13.7; 95% CI: 13.4%-13.9%) and in the number of CRCs diagnosed (34.1% reduction; 95% CI: 31.4%-36.8% vs. 26.7%; 95% CI: 24.6%-28.8%). Curative treatment was received by 87.5% of patients diagnosed with rectal cancer prepandemic and 80.7% of patients during the pandemic post-lockdown period (p = 0.002). CONCLUSIONS: The COVID-19 pandemic has led to a decrease in the number of diagnosed CRC cases and in the proportion of stage I CRC. The reduction in the number of colonoscopies and CRC diagnoses was higher in centers that applied universal SARS-CoV-2 PCR screening before colonoscopy. In addition, the COVID-19 pandemic has affected curative treatment of rectal cancers.

BACKGROUND & AIMS: Few prospective studies have assessed the safety of direct oral anticoagulants (DOACs) in elective endoscopy. Our primary aim was to compare the risks of endoscopy-related gastrointestinal bleeding and thromboembolic events in patients on DOACs or vitamin K antagonists (VKAs) in this setting. Secondarily, we examined the impact of the timing of anticoagulant resumption on the risk of delayed bleeding in high-risk therapeutic procedures. METHODS: We conducted a multicenter, prospective, observational study from January 2018 to March 2020 of 1602 patients on oral anticoagulants (1004 on VKAs and 598 on DOACs) undergoing 1874 elective endoscopic procedures. Our primary outcomes were 90-day thromboembolic events and 30-day endoscopy-related gastrointestinal bleeding. The inverse probability of treatment weighting propensity score method was used for baseline covariate adjustment. RESULTS: The 2 groups had similar risks of endoscopy-related gastrointestinal bleeding (VKAs vs DOACs, 6.2% vs 6.7%; adjusted odds ratio [OR], 1.05; 95% CI, 0.67-1.65) and thromboembolic events (VKAs vs DOACs, 1.3% vs 1.5%; adjusted OR, 0.90; 95% CI, 0.34-2.38). In high bleeding risk procedures (n = 747), delayed anticoagulant resumption (> 48 hours or 24-48 hours vs < 24 hours) did not reduce the risk of postprocedural bleeding (10.3%, 9%, and 5.8%, respectively; adjusted P = .43). Hot and cold snare polypectomy were the most frequent high-risk interventions (41.8% and 39.8%, respectively). CONCLUSION: In a prospective study of patients on DOACs or VKAs undergoing elective endoscopy, endoscopy-related bleeding and thromboembolic events showed similar risk. Our study suggests that early anticoagulant resumption is safe in most patients, but more data are needed for advanced high-risk therapeutic procedures.

Background: Small Bowel Capsule Endoscopy is the first-choice technique for investigating the majority of small bowel diseases. Its most common complications are related to incomplete examinations and capsule retention. There is no consensus on how patients with previous gastrointestinal surgery should receive the capsule. Objective: The primary endpoint was to compare the rate of complete small-bowel examinations (completion rate) between oral ingestion and endoscopic delivery of the capsule. The secondary endpoint was to compare diagnostic yield and adverse events in the two groups. Methods: A retrospective observational study was conducted in nine hospitals in Spain. Demographic data, previous surgery, indication for capsule endoscopy, intestinal transit time, diagnosis, completion rate (percentage of capsules reaching the caecum), diagnostic yield (percentage of results compatible with indication for the exam) and adverse events were collected. Results: From January 2009 to May 2019 fifty-seven patients were included (39 male, mean age 66±15 years). The most common indications for the exam were overt (50.9%) and occult (35.1%) small bowel bleeding. Previous Billroth II gastrectomy and Roux-en-Y gastric bypass were present in 52.6% and 17.5% of patients respectively. The capsule was swallowed in 34 patients and placed endoscopically in 23 patients. No significant differences were observed between the oral ingestion and endoscopic delivery groups in terms of completion rate (82.4% vs. 78.3%; p=0.742), diagnostic yield (41.2% vs. 52.2%; p=0.432) or small bowel transit time (301 vs. 377min, p=0.118). No capsule retention occurred. Only one severe adverse event (anastomotic perforation) was observed in the endoscopic delivery group. Conclusions: In our case series, there were no significant differences between oral ingestion and endoscopic delivery in terms of completion rate, diagnostic yield or safety.(AU)
Antecedentes: La cápsula endoscópica representa la técnica de primera elección para investigar la mayoría de las enfermedades del intestino delgado. Sus complicaciones más comunes frecuentes son las exploraciones incompletas y la retención a nivel de intestino delgado. Hasta el momento no hay acuerdo sobre cómo administrar la cápsula a los pacientes que han sido sometidos a una cirugía gastrointestinal previa. Objetivo: El objetivo principal fue comparar la tasa de estudios completos entre la ingestión oral y la administración endoscópica de la cápsula. Los objetivos secundarios fueron comparar el rendimiento diagnóstico y los eventos adversos en ambos grupos. Métodos: Se realizó un estudio observacional retrospectivo en 9 hospitales de España. Se recogieron datos demográficos, cirugía previa, indicación de cápsula endoscópica, tiempo de tránsito intestinal, diagnóstico, tasa de estudios completos (porcentaje de cápsulas que llegan al ciego), rendimiento diagnóstico (porcentaje de resultados compatibles con la indicación del examen) y eventos adversos. Resultados: Desde enero de 2009 hasta mayo de 2019 se incluyeron 57 pacientes (39 hombres, edad media 66 ± 15 años). Las indicaciones más frecuentes para el examen fueron hemorragia de intestino delgado «manifiesta» (50,9%) y «oculta» (35,1%). El 52,6% de los pacientes presentaba gastrectomía Billroth II y el 17,5% bypass gástrico en Y de Roux. La cápsula fue ingerida en 34 pacientes y colocada endoscópicamente en 23 pacientes. No se observaron diferencias significativas entre los grupos de ingesta oral y de colocación endoscópica en cuanto a tasa de estudios completos (82,4% vs. 78,3%; p = 0,742), rendimiento diagnóstico (41,2% vs. 52,2%; p = 0,432) y tiempo de tránsito del intestino delgado (301 vs. 377 min, p = 0,118). No hubo casos de cápsulas retenidas. Solo se observó un evento adverso severo (perforación anastomótica) en el grupo de colocación endoscópica...(AU)

BACKGROUND: The long-term outcome of patients after antitumour necrosis factor alpha (anti-TNF) discontinuation is not well known. AIMS: To assess the risk of relapse in the long-term after anti-TNF discontinuation. METHODS: This was an extension of the evolution after anti-TNF discontinuation in patients with inflammatory bowel disease (EVODIS) study (Crohn's disease or ulcerative colitis patients treated with anti-TNFs in whom these drugs were withdrawn after achieving clinical remission) based in the same cohort of patients whose outcome was updated. Clinical remission was defined as a Harvey-Bradshaw index ≤4 points in Crohn's disease, a partial Mayo score ≤2 in ulcerative colitis and the absence of fistula drainage despite gentle finger compression in perianal disease. RESULTS: This was an observational, retrospective, multicenter study. A total of 1055 patients were included. The median follow-up time was 34 months. The incidence rate of relapse was 12% per patient-year (95% confidence interval [CI] = 11-14). The cumulative incidence of relapse was 50% (95% CI = 47-53): 19% at one year, 31% at 2 years, 38% at 3 years, 44% at 4 years and 48% at 5 years of follow-up. Of the 60% patients retreated with the same anti-TNF after relapse, 73% regained remission. Of the 75 patients who did not respond, 48% achieved remission with other therapies. Of the 190 patients who started other therapies after relapse, 62% achieved remission with the new treatment. CONCLUSIONS: A significant proportion of patients who discontinued the anti-TNF remained in remission. In case of relapse, retreatment with the same anti-TNF was usually effective. Approximately half of the patients who did not respond after retreatment achieved remission with other therapies.

OBJECTIVES: Transjugular intrahepatic portosystemic shunt (TIPS) is increasingly used in the management of refractory ascites. Controversy exists regarding the predictive factors of unfavorable outcomes, useful for patient selection. The primary aim was to identify predictive factors of 1-year survival or recurrent severe hepatic encephalopathy in patients with cirrhosis undergoing covered TIPS for refractory ascites. The secondary aim was overall survival. METHODS: Observational, retrospective, multicentric study, that included all cirrhotic patients treated with covered-TIPS for refractory ascites since 2001. Demographic, clinical, laboratory and hemodynamic data were collected at baseline and consecutively until dead, liver transplant or end of follow-up. The Cox model was used to identify predictive factors of overall survival. A Fine-Gray competing risk regression model was used to identify predictive factors of 1-year mortality or recurrent hepatic encephalopathy. A predictive nomogram was created based on those factors. RESULTS: In total 159 patients were included. Predictive factors of survival or recurrent severe encephalopathy were renal dysfunction [hazard ratio, 2.12 (95% CI, 1.11-4.04); P = 0.022], albumin [hazard ratio, 0.58 (95% CI, 0.34-0.97); P = 0.036], serum sodium [hazard ratio, 0.94 (95% CI, 0.89-0.98); P = 0.008] and international normalized ratio [hazard ratio 4.27 (95% CI, 1.41-12.88); P = 0.010]. In the competing risk analysis, predictive factors of 1-year mortality/recurrent severe encephalopathy in multivariate analysis were age [sub-distribution hazard ratio (sHR) 1.05 (95% CI, 1.02-1.09); P = 0.001], creatinine [sHR 1.55 (95% CI, 1.23-1.96); P = 0.001] and serum sodium [sHR 0.94 (95% CI, 0.90-0.99); P = 0.011] at baseline. CONCLUSIONS: Age, creatinine and sodium baseline levels strongly influence 1-year survival/recurrent severe hepatic encephalopathy in patients with cirrhosis undergoing covered TIPS for refractory ascites. A simple nomogram accurately and easily identifies those patients with worse prognosis.

No capsule retention occurred. Only one severe adverse event (anastomotic perforation) was observed in the endoscopic delivery group. CONCLUSIONS: In our case series, there were no significant differences between oral ingestion and endoscopic delivery in terms of completion rate, diagnostic yield or safety. Being less invasive, oral ingestion of the capsule should be the first-choice method in patients with previous gastrointestinal surgery.

Background: Data about use and effectiveness of mercaptopurine in inflammatory bowel disease are relatively limited. Aims: To assess the possible therapeutic indications, efficacy and safety of mercaptopurine as an alternative to azathioprine in inflammatory bowel disease. Methods: Retrospective observational study in patients treated with mercaptopurine in a total cohort of 1,574 patients with inflammatory bowel disease. Results: One hundred and fifty-two patients received mercaptopurine, 15.7% of these patients as an initial thiopurine, 5.3% after azathioprine failure, and 79% after azathioprine intolerance. In 52.6% of patients (n = 80), adverse effects of mercaptopurine occurred, resulting in withdrawal in 49 of them. Mercaptopurine was effective in 39% of cases (95% CI 31-48%). In the remaining patients, failure was due mainly to withdrawal due to side effects (55.1%) and therapeutic step-up (33.7%). The average total time of mercaptopurine exposure was 36 months (IQR: 2-60). Myelotoxicitywith mercaptopurine was more common in patients with intermediate TPMT activity than in those with normal activity (p = 0.046). Conclusions: In our setting, mercaptopurine is primarily used as a rescue therapy in patients with azathioprine adverse effects. This could explain its modest efficacy and the high rate of adverse effects. However, this drug is still an alternative in this group of patients, before a therapeutic step-up to biologics is considered (AU)

INTRODUCCIÓN: El tratamiento de la hepatitis crónica B antígeno e negativa (HCB HBeAg negativa) con antivíricos orales (AO) suele prolongarse de forma indefinida debido a que la pérdida del antígeno de superficie como objetivo para su suspensión es un hecho infrecuente. Recientemente han aparecido las primeras evidencias que sugieren finalizar la terapia con AO en casos seleccionados. OBJETIVOS: Analizar la tasa de rebote virológico en pacientes con HCB Age negativa que suspendieron el tratamiento con AO. MATERIAL Y MÉTODOS: Estudio retrospectivo observacional que incluyó 140 casos de HCB HBeAg negativa. Veintidós pacientes, que recibieron exclusivamente AO, los suspendieron por diversos motivos realizándose un seguimiento posterior. Todos presentaban transaminasas normales, ADN indetectable y ausencia de cirrosis o comorbilidades importantes al finalizar el tratamiento. RESULTADOS: Doce pacientes presentaron rebote virológico (54,54%), transcurriendo una media de 6,38 meses (± 1,9) desde la suspensión hasta el rebote (el 75% dentro de los 12 primeros meses tras la suspensión). Cinco recibieron adefovir, uno lamivudina más adefovir, uno tenofovir y 5 lamivudina. La duración media del tratamiento, desde el inicio hasta la suspensión, fue de 38,5 meses (± 4,5). El grupo con respuesta sostenida presentaba una edad media y duración del tratamiento superior a los sujetos con rebote, si bien estas diferencias no resultaron estadísticamente significativas. CONCLUSIONES: Los resultados sugieren que es posible suspender la terapia con AO en casos seleccionados de HCB Age negativa, siempre que no exista cirrosis, se cumpla un tiempo mínimo de tratamiento, las transaminasas sean normales y el ADN indetectable de forma mantenida. En estos casos, se debe realizar un seguimiento estrecho durante el primer año y posteriormente de forma indefinida
BACKGROUND: Treatment of HBeAg-negative chronic hepatitis B (CHB) with nucleos(t)ide analogues (NA) is usually indefinite, since the loss of HBsAg, as a criterion for its discontinuation, is a rare event. Recent evidence suggests that discontinuing NA therapy may be feasible in selected patients. OBJECTIVES: To analyze the rate of virological relapse in patients with HBeAg-negative CHB who discontinued treatment with NAs. METHODS: We performed a single-center observational study that included 140 patients with HBsAg-negative CHB. Twenty-two patients, who received only NAs, discontinued treatment for different reasons and were subsequently monitored. All had normal ALT and AST, undetectable DNA and absence of cirrhosis or significant comorbidities before stopping treatment. RESULTS: Twelve patients showed virologic relapse (54.54%). The mean interval between discontinuation and relapse was 6.38 months (± 1.9) (75% relapsed during the first 12 months after discontinuation). Five received adefovir, 1 lamivudine and adefovir, 1 tenofovir and 5 lamivudine alone. The mean treatment duration in this group was 38.5 months (± 4.5). The sustained response group had a higher mean age and longer treatment duration than patients with virologic relapse but these differences were not statistically significant. CONCLUSIONS: The results suggest that NA treatment can be stopped in selected patients with CHB as long as they are not cirrhotic, have completed a minimum period of treatment, have normal ALT and sustained undetectable DNA. These patients should be closely monitored during the first year and then indefinitely

INTRODUCCIÓN: La hemorragia digestiva de origen oscuro (HDOO) es aquella en la que no se consigue identificar su origen tras la evaluación mediante endoscopia digestiva alta y baja. En esos casos se sospecha un origen en intestino delgado. La HDOO puede ser oculta o manifiesta. El objetivo de este estudio es analizar las características clínico-analíticas, los hallazgos de la cápsula endoscópica e investigar qué factores se relacionan con la detección de lesiones en ambas formas de presentación. MÉTODOS: Estudio retrospectivo sobre las cápsulas endoscópicas realizadas entre noviembre de 2009 y noviembre de 2012 para el estudio de HDOO. RESULTADOS: Se analizaron 284 exploraciones de 272 pacientes. Inicialmente, 12 fueron no valorables y se repitieron, analizando finalmente las cápsulas evaluables (272). Ciento catorce (41,9%) fueron normales. Los pacientes con HDOO manifiesta tenían significativamente mayor edad (70,2 vs. 67,5 años; p = 0,04), consumían más AINE (24,2% vs. 11,9%; p = 0,01), tenían menores niveles de hemoglobina (9,3 vs. 10,4; p < 0,001) y requirieron más transfusiones (64,5% vs. 32,2%; p < 0,001) respecto a los pacientes con HDOO oculta. La detección de lesiones del tipo afta-úlcera y pólipo-masa no mostró diferencias significativas entre ambas formas de presentación. Las lesiones vasculares se detectaron con mayor frecuencia en la forma de HDOO manifiesta respecto a la forma oculta (40,3% vs. 25,7%, respectivamente), (p < 0,05). Considerando el total de diagnósticos realizados por la cápsula, no se observaron diferencias en la capacidad diagnóstica entre la forma manifiesta (57%) y la forma oculta (54%), (p = 0,6). El análisis multivariado mostró cómo el consumo de fármacos: AINE (OR 2,75; p = 0,01), antiagregantes y anticoagulantes (OR 2,64; p = 0,03), así como datos analíticos: hemoglobina (OR 3,23; p < 0,001) e INR (OR 1,8; p = 0,02) predijeron de forma estadísticamente significativa la detección de lesiones con la cápsula endoscópica en la forma de HDOO manifiesta. En la forma de presentación oculta, el análisis multivariado mostró que la edad (OR 1,9; p = 0,04) y el consumo de AINE (OR 2,1; p = 0,01) estaban estadísticamente relacionados con la detección de lesiones en la cápsula. CONCLUSIONES: La cápsula endoscópica es fundamental en la valoración de la HDOO. Aunque la capacidad diagnóstica fue similar entre ambas formas de presentación, las lesiones vasculares se detectaron con mayor frecuencia en el subtipo manifiesta. Teniendo en cuenta la forma de presentación de la HDOO (manifiesta vs. oculta) y algunas características clínico-analíticas de los pacientes (edad, consumo de fármacos, hemoglobina) se podría optimizar la capacidad diagnóstica de la cápsula
INTRODUCTION: Obscure gastrointestinal bleeding (OGIB) is defined as bleeding from the gastrointestinal tract with no obvious cause after assessment with upper and lower gastrointestinal endoscopy. In these cases, the source is suspected to be in the small bowel. Obscure bleeding can be occult or overt. The aim of this study was to analyze the clinical and analytical characteristics and findings on capsule endoscopy in patients with OGIB and to determine the factors related to the detection of lesions in both forms of presentation. METHODS: We performed a retrospective study of capsule endoscopies carried out between November 2009 and November 2012 for OGIB. RESULTS: We analyzed 284 capsule endoscopies in 272 patients. Initially, 12 procedures could not be evaluated and were repeated. A total of 272 procedures were finally included in the analysis. The results of 114 (41.9%) capsule endoscopies were normal. Compared with patients with occult OGIB, those with overt OGIB were significantly older (70.2 vs. 67.5 years; p = 0.04), consumed more NSAID (24.2% vs. 11.9%; p = 0.01), had higher hemoglobin levels (9.3 vs. 10.4; p < 0,001) and more frequently required transfusion (64.5% vs 32.2%; p < 0.001). No differences were found between the two forms of presentation in the detection of canker sores-ulcers and polyps-masses. Vascular lesions were more frequently detected in overt than in occult OGIB (40.3% vs. 25.7%, respectively), (p < 0.05). When the total number of diagnoses carried out by capsule endoscopy was analyzed, no differences were found in diagnostic yield between overt OGIB (57%) and occult OGIB (54%), (p = 0.6). In overt OGIB, multivariate analysis showed that the variables that significantly predicted the detection of lesions on capsule endoscopy were consumption of medication NSAID (OR 2.75; p = 0.01), antiplatelets and anticoagulants (OR 2.64; p = 0.03) and analytical data hemoglobin (OR 3.23; p < 0.001) and INR (OR 1.8; p = 0.02). In occult OGIB, multivariate analysis showed that the factors significantly related to the detection of lesions on endoscopy were age (OR 1.9; p = 0.04) and NSAID consumption (OR 2.1; p = 0.01). CONCLUSIONS: Capsule endoscopy is essential in the assessment of OGIB. Although the diagnostic yield was similar in both forms of presentation, vascular lesions were more frequently detected in overt OGIB. The diagnostic yield of capsule endoscopy could be optimized by taking into account the form of presentation (overt vs. occult) and certain clinical and analytic data (age, drug consumption, hemoglobin) (AU)

INTRODUCTION: Obscure gastrointestinal bleeding (OGIB) is defined as bleeding from the gastrointestinal tract with no obvious cause after assessment with upper and lower gastrointestinal endoscopy. In these cases, the source is suspected to be in the small bowel. Obscure bleeding can be occult or overt. The aim of this study was to analyze the clinical and analytical characteristics and findings on capsule endoscopy in patients with OGIB and to determine the factors related to the detection of lesions in both forms of presentation. METHODS: We performed a retrospective study of capsule endoscopies carried out between November 2009 and November 2012 for OGIB. RESULTS: We analyzed 284 capsule endoscopies in 272 patients. Initially, 12 procedures could not be evaluated and were repeated. A total of 272 procedures were finally included in the analysis. The results of 114 (41.9%) capsule endoscopies were normal. Compared with patients with occult OGIB, those with overt OGIB were significantly older (70.2 vs. 67.5 years; p = 0.04), consumed more NSAID (24.2% vs. 11.9%; p = 0.01), had higher hemoglobin levels (9.3 vs. 10.4; p < 0,001) and more frequently required transfusion (64.5% vs 32.2%; p < 0.001). No differences were found between the two forms of presentation in the detection of canker sores-ulcers and polyps-masses. Vascular lesions were more frequently detected in overt than in occult OGIB (40.3% vs. 25.7%, respectively), (p < 0.05). When the total number of diagnoses carried out by capsule endoscopy was analyzed, no differences were found in diagnostic yield between overt OGIB (57%) and occult OGIB (54%), (p = 0.6). In overt OGIB, multivariate analysis showed that the variables that significantly predicted the detection of lesions on capsule endoscopy were consumption of medication NSAID (OR 2.75; p = 0.01), antiplatelets and anticoagulants (OR 2.64; p = 0.03) and analytical data hemoglobin (OR 3.23; p < 0.001) and INR (OR 1.8; p = 0.02). In occult OGIB, multivariate analysis showed that the factors significantly related to the detection of lesions on endoscopy were age (OR 1.9; p = 0.04) and NSAID consumption (OR 2.1; p = 0.01). CONCLUSIONS: Capsule endoscopy is essential in the assessment of OGIB. Although the diagnostic yield was similar in both forms of presentation, vascular lesions were more frequently detected in overt OGIB. The diagnostic yield of capsule endoscopy could be optimized by taking into account the form of presentation (overt vs. occult) and certain clinical and analytic data (age, drug consumption, hemoglobin).
