Background & Aims:
Endoscopic therapy reduces the rebleeding rate, the need for surgery, and the mortality in patients with peptic ulcer and active bleeding or visible vessel. Injection of ...epinephrine is the most popular therapeutic method. Guidelines disagree on the need for a second hemostatic procedure immediately after epinephrine; although it seems to reduce further bleeding, its effects on morbidity, surgery rates, and mortality remain unclear. The aim of this study was to perform a systematic review and meta-analysis to determine whether the addition of a second procedure improves hemostatic efficacy and/or patient outcomes after epinephrine injection.
Methods:
An extensive search for randomized trials comparing epinephrine alone vs. epinephrine plus a second method was performed in MEDLINE and EMBASE and in the abstracts of the AGA Congresses between 1990 and 2002. Selected articles were included in a meta-analysis.
Results:
Sixteen studies including 1673 patients met inclusion criteria. Adding a second procedure reduced the further bleeding rate from 18.4% to 10.6% (Peto odds ratio 0.53, 95% CI: 0.40–0.69) and emergency surgery from 11.3% to 7.6% (OR: 0.64, 95% CI: 0.46–0.90). Mortality fell from 5.1% to 2.6% (OR: 0.51, 95% CI: 0.31–0.84). Subanalysis showed that the risk of further bleeding decreased regardless of which second procedure was applied. In addition, the risk was reduced in all subgroups, although reduction was more evident in high-risk patients and when no scheduled follow-up endoscopies were performed.
Conclusions:
Additional endoscopic treatment after epinephrine injection reduces further bleeding, need for surgery, and mortality in patients with bleeding peptic ulcer.
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.
Fast-track colonoscopy to detect patients with colorectal cancer based on high-risk symptoms is associated with low sensitivity and specificity. The aim was to derive a predictive score of advanced ...colonic neoplasia in symptomatic patients in fast-track programs.
All patients referred for fast-track colonoscopy were evaluated. Faecal immunological haemoglobin test (3 samples; positive> 4 μg Hb/g), and a survey to register clinical variables of interest were performed. Colorectal cancer and advanced adenoma were considered as advanced colonic neoplasia. A sample size of 600 and 500 individuals were calculated for each phase 1 and phase 2 of the study, respectively (Phase 1, derivation and Phase 2, validation cohort). A Bayesian logistic regression analysis was used to derive a predictive score.
1495 patients were included. Age (OR, 21), maximum faecal-Hb value (OR, 2.3), and number of positive samples (OR, 28) presented the highest ORs predictive of advanced colonic neoplasia. The additional significant predictive variables adjusted for age and faecal-Hb variables in Phase 1 were previous colonoscopy (last 5 years) and smoking (no, ex/active). With these variables a predictive score of advanced colonic neoplasia was derived. Applied to Phase 2, patients with a Score > 20 had an advanced colonic neoplasia probability of 66% (colorectal cancer, 32%), while those with a Score ≤ 10, a probability of 10% (colorectal cancer, 1%). Prioritizing patients with Score > 10, 49.4% of patients would be referred for fast-track colonoscopy, diagnosing 98.3% of colorectal cancers and 77% of advanced adenomas.
A scoring system was derived and validated to prioritize fast-track colonoscopies according to risk, which was efficient, simple, and robust.

Abstract 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)
Guidelines recommend using prognostic scales for risk stratification in patients with non-variceal upper gastrointestinal bleeding. It remains unclear whether risk scores offer greater accuracy than ...clinical evaluation.
Compare the diagnostic accuracy of the endoscopist's judgment against different risk-scoring systems (Rockall, Glasgow-Blatchford, Baylor and the Cedars-Sinai scores) for predicting outcomes in peptic ulcer bleeding (PUB).
Between February 2006 and April 2010 we prospectively recruited 401 patients with peptic ulcer bleeding; 225 received endoscopic treatment. The endoscopist recorded his/her subjective assessment ("endoscopist judgment") of the risk of rebleeding and death immediately after endoscopy for each patient. Independent evaluators calculated the different scores. Area under the receiver-operating-characteristics (ROC) curve, sensitivity, specificity, positive and negative predictive values were calculated for rebleeding and mortality.
: The areas under ROC curve of the endoscopist's clinical judgment for rebleeding (0.67-0.75) and mortality (0.84-0.9) were similar or even superior to the different risk scores in both the whole group and in patients receiving endoscopic therapy.
The accuracy of the currently available risk scores for predicting rebleeding and mortality in PUB patients was moderate and not superior to the endoscopist's judgment. More precise prognostic scales are needed.
There is no consensus about the possible relation between in-hospital mortality in surgery for gastric cancer and the hospital annual volume of interventions. The objectives were to identify factors ...associated to greater in-hospital mortality for surgery in gastric cancer and to analyze the possible independent relation between hospital annual volume and in-hospital mortality.
We performed a retrospective cohort study of all patients discharged after surgery for stomach cancer during 2001-2002 in four regions of Spain using the Minimum Basic Data Set for Hospital Discharges. The overall and specific in-hospital mortality rates were estimated according to patient and hospital characteristics. We adjusted a logistic regression model in order to calculate the in-hospital mortality according to hospital volume.
There were 3241 discharges in 144 hospitals. In-hospital mortality was 10.3% (95% CI 9.3-11.4). A statistically significant relation was observed among age, type of admission, volume, and mortality, as well as diverse secondary diagnoses or the type of intervention. Hospital annual volume was associated to Charlson score, type of admission, region, length of stay and number of secondary diagnoses registered at discharge. In the adjusted model, increased age and urgent admission were associated to increased in-hospital mortality. Likewise, partial gastrectomy (Billroth I and II) and simple excision of lymphatic structure were associated with a lower probability of in-hospital mortality. No independent association was found between hospital volume and in-hospital mortality
Despite the limitations of our study, our results corroborate the existence of patient, clinical, and intervention factors associated to greater hospital mortality, although we found no clear association between the volume of cases treated at a centre and hospital mortality.

To compare the impact of an unrestricted diet with a 3-day low-residue diet before colonoscopy on bowel preparation quality.
A randomized, multicenter, researcher-blinded, parallel-group feasibility ...trial was conducted to assess the efficacy of an unrestricted diet versus a 3-day low-residue diet for colonoscopy preparation. Participants, aged 50 to 69, were enrolled in a colorectal cancer screening program with no factors linked to poor bowel cleansing. The Boston Bowel Preparation Scale was used to evaluate colon preparation during intubation and withdrawal. Secondary outcomes included bowel exploration time, adenoma and polyp detection rates, and preparation and diet tolerability. The trial is registered under Clinical Trials (NCT04664543).
One hundred and two individuals (mean age 59.3 ± 5.5 years, 40.1% female) were randomly assigned to each diet. All participants in both groups achieved adequate preparation (Boston scores ≥ 2 in each segment). Complete adherence to preparation was observed in the majority of participants in both groups. No significant differences were noted between groups in withdrawal or cecal intubation times, or in adenoma detection rates. The unrestricted diet was better tolerated than the 3-day low-residue diet (82.5% vs. 32.3%). Preparation assessed during intubation was adequate in 82.5% of the unrestricted diet group and in 90.3% of the 3-day low-residue diet group.
It is feasible to test the impact of an unrestricted diet for adequate bowel preparation. Comparable cleansing results were achieved, but the unrestricted diet showed better tolerability.
Background: The optimal therapy for bleeding small bowel vascular lesions is controversial. This study investigated the efficacy and safety of endoscopic band ligation in this clinical condition.
...Methods: Fourteen patients bleeding from angiodysplasia and 4 bleeding from Dieulafoy's lesions located in the small bowel were included in this pilot study. Endoscopic band ligation was performed by using less than 200 mBar negative pressure in suctioning the target lesion into the ligation cap just before band release. Mean follow-up was 18 months (range 6–31 months).
Observations: Endoscopic band ligation achieved hemostasis in a single session in all patients. No adverse events occurred except for mild abdominal pain in two patients. Mortality was null, and no patient required further blood transfusion during the 40 days after endoscopic band ligation. No patient with Dieulafoy's lesion had further bleeding, whereas bleeding recurred in 6 of 14 (43%) patients with angiodysplasia during long-term follow-up.
Conclusions: Endoscopic band ligation is safe and effective for treatment of acutely bleeding small bowel vascular lesions. Although endoscopic band ligation is definitive therapy for Dieulafoy's lesion, long-term efficacy in the treatment of Gl bleeding from angiodysplasia is limited.
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.
To compare the predictive values of haemoglobin alone and the Oakland score for predicting outcomes in ALGIB patients.
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.
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.
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 hemorragia digestiva baja (HDB) aguda es una causa frecuente de hospitalización. Guías recientes recomiendan el uso de escalas pronósticas para la estratificación del riesgo. Sin embargo, aún no está claro si los índices de riesgo son más precisos en cuanto a pronóstico que algunas variables más simples.
Comparar el valor predictivo aislado de la hemoglobina con el índice pronóstico de Oakland para predecir resultados en pacientes con HDB.
Estudio retrospectivo unicéntrico realizado en un hospital universitario. Los datos se extrajeron de las historias clínicas del hospital. La puntuación del score de Oakland se calculó en el momento del ingreso. Los resultados a valorar en el estudio se definieron igual que el artículo original que describe el índice de Oakland: alta segura (el resultado primario del score de Oakland), transfusión, resangrado, reingreso, intervención terapéutica y muerte. Para cada resultado se calcularon el área bajo la curva (AUROC) y la precisión utilizando la hemoglobina y el índice de Oakland.
Se incluyeron 258 pacientes. Ochenta y cuatro (32,6%) necesitaron transfusión, 50 (19,4%) presentaron resangrado, 31 (12,1%) requirieron intervención terapéutica, 20 (7,8%) reingresaron y 6 (2,3%) fallecieron. No hubo diferencias en los valores de la curva AUROC de la hemoglobina frente al índice de Oakland con respecto al alta segura (0,82 0,77-0,88 vs a 0,80 0,74-0,86, respectivamente) ni a la intervención terapéutica y la muerte. La hemoglobina fue significativamente mejor para predecir transfusión y resangrado, y el índice de Oakland fue significativamente mejor para predecir reingreso.
En nuestro estudio, el índice de Oakland no fue mejor que la hemoglobina aislada para predecir resultados en pacientes con HDB. La utilidad de los índices de riesgo para predecir resultados en la práctica clínica sigue siendo incierta.
Prediction models for colorectal cancer (CRC) detection in symptomatic patients, based on easily obtainable variables such as fecal haemoglobin concentration (f‐Hb), age and sex, may simplify CRC ...diagnosis. We developed, and then externally validated, a multivariable prediction model, the FAST Score, with data from five diagnostic test accuracy studies that evaluated quantitative fecal immunochemical tests in symptomatic patients referred for colonoscopy. The diagnostic accuracy of the Score in derivation and validation cohorts was compared statistically with the area under the curve (AUC) and the Chi‐square test. 1,572 and 3,976 patients were examined in these cohorts, respectively. For CRC, the odds ratio (OR) of the variables included in the Score were: age (years): 1.03 (95% confidence intervals (CI): 1.02–1.05), male sex: 1.6 (95% CI: 1.1–2.3) and f‐Hb (0–<20 µg Hb/g feces): 2.0 (95% CI: 0.7–5.5), (20‐<200 µg Hb/g): 16.8 (95% CI: 6.6–42.0), ≥200 µg Hb/g: 65.7 (95% CI: 26.3–164.1). The AUC for CRC detection was 0.88 (95% CI: 0.85–0.90) in the derivation and 0.91 (95% CI: 0.90–093; p = 0.005) in the validation cohort. At the two Score thresholds with 90% (4.50) and 99% (2.12) sensitivity for CRC, the Score had equivalent sensitivity, although the specificity was higher in the validation cohort (p < 0.001). Accordingly, the validation cohort was divided into three groups: high (21.4% of the cohort, positive predictive value—PPV: 21.7%), intermediate (59.8%, PPV: 0.9%) and low (18.8%, PPV: 0.0%) risk for CRC. The FAST Score is an easy to calculate prediction tool, highly accurate for CRC detection in symptomatic patients.
What's new?
Lower gastrointestinal symptoms potentially indicative of colorectal cancer (CRC) are a common reason for physician visits. While the probability that any one of those symptoms is associated with CRC is low, identifying patients for further screening remains a challenge. Here, the possibility of improving CRC diagnostic accuracy and risk stratification was explored using a three‐variable FAST Score based on fecal hemoglobin concentration, age, and sex. Among symptomatic patients referred to colonoscopy, the FAST Score prediction model identified three risk groups, the lowest of which ruled out CRC. Threshold scores were sensitive across variables, including country, age, and sex.
