Endoscopic treatment (endoscopic balloon dilation/self-expandable metal stent) vs surgical resection for the treatment of de novo stenosis in Crohn's disease (ENDOCIR study): an open-label, multicentre, randomized trial.

BACKGROUND: Stenosis is one of the most common complications in patients with Crohn's disease (CD). Endoscopic balloon dilation (EBD) is the treatment of choice for a short stenosis adjacent to the anastomosis from previous surgery. Self-expandable metal stents (SEMS) may be a suitable treatment option for longer stenoses. To date, however, there is no scientific evidence as to whether endoscopic (EBD/SEMS) or surgical treatment is the best approach for de novo or primary stenoses that are less than 10 cm in length. METHODS/DESIGN: Exploratory study as "proof-of-concept", multicentre, open-label, randomized trial of the treatment of de novo stenosis in the CD; endoscopic treatment (EBD/SEMS) vs surgical resection (SR). The type of endoscopic treatment will initially be with EDB; if a therapeutic failure occurs, then a SEMS will be placed. We estimate 2 years of recruitment and 1 year of follow-up for the assessment of quality of life, costs, complications, and clinical recurrence. After the end of the study, patients will be followed up for 3 years to re-evaluate the variables over the long term. Forty patients with de novo stenosis in CD will be recruited from 15 hospitals in Spain and will be randomly assigned to the endoscopic or surgical treatment groups. The primary aim will be the evaluation of the patient quality of life at 1 year follow-up (% of patients with an increase of 30 points in the 32-item Inflammatory Bowel Disease Questionnaire (IBDQ-32). The secondary aim will be evaluation of the clinical recurrence rate, complications, and costs of both treatments at 1-year follow-up. DISCUSSION: The ENDOCIR trial has been designed to determine whether an endoscopic or surgical approach is therapeutically superior in the treatment of de novo stenosis in CD.

Self-expandable metal stents versus endoscopic balloon dilation for the treatment of strictures in Crohn's disease (ProtDilat study): an open-label, multicentre, randomised trial.

BACKGROUND: Endoscopic balloon dilation (EBD) is the established endoscopic treatment for short strictures in Crohn's disease. Fully covered self-expandable metal stents (FCSEMS) have been used for endoscopic treatment of patients for whom EBD was unsuccessful. We aimed to determine the efficacy and safety of the two endoscopic treatments in patients with Crohn's disease with stenosis and compare the mean cost of both treatments. METHODS: This multicentre, open-label, randomised trial was done in 19 tertiary and secondary hospitals in Spain. Patients with Crohn's disease with obstructive symptoms and predominantly fibrotic strictures of less than 10 cm in length were eligible for inclusion. We excluded patients with stenosis treated with SEMS or EBD in the previous year and stenosis not accessible to a colonoscope. Patients were randomly assigned (1:1) to receive either EBD (EBD group) or FCSEMS (FCSEMS group) using a digital en-block randomisation system (block size of four). In the EBD group, dilation was done with a CRE Boston Scientific (Marlborough, MA, USA) pneumatic balloon with the diameter set at the discretion of the endoscopist; a maximum of two sessions of dilation were allowed with a minimum interval of 15-30 days between them. In the FCSEMS group, a 20 mm diameter Taewoong (Gimpo-si, South Korea) fully covered metal stent was placed; stent length was set at the discretion of the endoscopist. The primary outcome was to assess the efficacy of the endoscopic treatment, defined by the proportion of patients free of a new therapeutic intervention (EBD, FCSEMS, or surgery) due to symptomatic recurrence at 1 year of follow-up. Patients were analysed according to the intention-to-treat principle. Adverse events were recorded for all the patients; events were considered associated to be with the procedure when a causal association was possible, probable, or definite. This trial is registered with ClinicalTrials.gov, NCT02395354. FINDINGS: From Aug 28, 2013, to Oct 9, 2017, we assessed the eligibility of 99 patients, of whom 19 (19%) patients were excluded. Thus, 80 (81%) patients were randomly assigned to treatment: 39 (49%) patients to the FCSEMS group and 41 (51%) patients to the EBD group. 33 (80%) of 41 patients in the EBD group and 20 (51%) of 39 patients in the FCSEMS group were free of a new therapeutic intervention at 1 year (odds ratio [OR] 3·9 [95% CI 1·4-10·6]; p=0·0061). Two (3%) of 80 patients had severe adverse events (one [2%] patient in the EBD group and one [3%] patient in the FCSEMS group); both patients had perforations. INTERPRETATION: EBD is more effective than FCSEMS for Crohn's disease strictures, with a good safety profile for both treatments.

Location, morphology and invasiveness of lateral spreading tumors in the colorectum differ between two large cohorts from an eastern and western country.

BACKGROUND AND STUDY AIMS: Data from Japanese series show that surface morphology of laterally spreading tumors (LST) in the colon identifies lesions with different incidence and pattern of submucosal invasion. Such data from western countries are scarce. We compared clinical and histological features of LST in a western country and an eastern country, with special interest on mucosal invasiveness of LST, and investigated the effect of clinical factors on invasiveness in both countries. PATIENTS AND METHODS: Patients with LST lesions ≥20mm were included from a multicenter prospective registry in Spain and from a retrospective registry from the National Cancer Center Hospital East, Japan. The primary outcome was the presence of submucosal invasion in LST. The secondary outcome was the presence of high-risk histology, defined as high-grade dysplasia or submucosal invasion. RESULTS: We evaluated 1102 patients in Spain and 663 in Japan. Morphological and histological characteristics differed. The prevalence of submucosal invasion in Japan was six-fold the prevalence in Spain (Prevalence Ratio PR=5.66; 95%CI: 3.96, 8.08), and the prevalence of high-risk histology was 1.5 higher (PR=1.44; 95%CI: 1.31, 1.58). Compared to the granular homogeneous type and adjusted by clinical features, granular mixed, flat elevated, and pseudo-depressed types were associated with higher odds of submucosal invasion in Japan, whereas only the pseudo-depressed type showed higher risk in Spain. Regarding high-risk histology, both granular mixed and pseudo-depressed were associated with higher odds in Japan, compared with only the granular mixed type in Spain. CONCLUSION: This study reveals differences in location, morphology and invasiveness of LST in an eastern and a western cohort.

Cardiorespiratory complications directly related to endoscopy: associated or not with sedation?

With the advent of routine sedation in digestive endoscopy, specifically the use of propofol, multiple reports have focused on the complications that may potentially emerge because of sedation, and whether administration is safer by anesthetists or trained gastroenterologists. Complications associated with endoscopy itself, whether diagnostic or therapeutic, have also been described. However, the fact that both upper and lower endoscopy per se may be accompanied by complications, both during the procedure or thereafter, is usually overlooked.

Gastric ulcers with upper gastrointestinal bleeding in patients with severe SARS-CoV-2.

A new coronavirus, SARS-CoV-2, was identified earlier this year and spread rapidly globally. The clinical manifestations that it produces have gradually become known and the typical clinical picture is respiratory. Although gastrointestinal symptoms have been described in several communications, information on endoscopic findings in these patients is practically zero. We describe two cases of upper gastrointestinal bleeding in patients with COVID-19. In both cases, the presence of gastric ulcers was identified in an unusual location, the gastric fundus. After ruling out malignancy, our suspicion was an ischemic etiology that is consistent with terminal gastric vascularization at the gastric fundus level and increased thrombotic phenomena in patients with COVID-19.

Safety in digestive endoscopy during the ongoing COVID-19 pandemic.

We read with interest the study by Hernández-Camba et al. about the low value of antibody testing for COVID-19 before endoscopic procedures and we would like to make some comments. Nine months after the first state of alarm was declared in Spain due to the SARS-CoV-2 pandemic, we knew that infections in endoscopy staff were scarce if adequate protection was worn and non-urgent procedures were postponed in patients with an active infection. Therefore, the conclusions of the study currently appear to be self-evident. However, things were different at the time it was performed.

The effect of Adacolumn® on ulcerative colitis with COVID-19.

Clinical validation of risk scoring systems to predict risk of delayed bleeding after EMR of large colorectal lesions.

BACKGROUND AND AIMS: The Endoscopic Resection Group of the Spanish Society of Endoscopy (GSEED-RE) model and the Australian Colonic Endoscopic Resection (ACER) model were proposed to predict delayed bleeding (DB) after EMR of large superficial colorectal lesions, but neither has been validated. We validated and updated these models. METHODS: A multicenter cohort study was performed in patients with nonpedunculated lesions ≥20 mm removed by EMR. We assessed the discrimination and calibration of the GSEED-RE and ACER models. Difficulty performing EMR was subjectively categorized as low, medium, or high. We created a new model, including factors associated with DB in 3 cohort studies. RESULTS: DB occurred in 45 of 1034 EMRs (4.5%); it was associated with proximal location (odds ratio [OR], 2.84; 95% confidence interval [CI], 1.31-6.16), antiplatelet agents (OR, 2.51; 95% CI, .99-6.34) or anticoagulants (OR, 4.54; 95% CI, 2.14-9.63), difficulty of EMR (OR, 3.23; 95% CI, 1.41-7.40), and comorbidity (OR, 2.11; 95% CI, .99-4.47). The GSEED-RE and ACER models did not accurately predict DB. Re-estimation and recalibration yielded acceptable results (GSEED-RE area under the curve [AUC], .64 [95% CI, .54-.74]; ACER AUC, .65 [95% CI, .57-.73]). We used lesion size, proximal location, comorbidity, and antiplatelet or anticoagulant therapy to generate a new model, the GSEED-RE2, which achieved higher AUC values (.69-.73; 95% CI, .59-.80) and exhibited lower susceptibility to changes among datasets. CONCLUSIONS: The updated GSEED-RE and ACER models achieved acceptable prediction levels of DB. The GSEED-RE2 model may achieve better prediction results and could be used to guide the management of patients after validation by other external groups.

Lesiones gastrointestinales en pacientes con enfermedad renal crónica y anemia / Gastrointestinal lesions in chronic kidney disease patients with anaemia

Introducción: A pesar de la frecuencia con que la anemia está presente en los pacientes con enfermedad renal crónica (ERC), su relación con lesiones gastrointestinales no ha sido estudiada. Método: Estudio observacional analítico transversal de un año de reclutamiento para determinar la prevalencia de lesiones gastrointestinales endoscópicas y los factores de riesgo asociados en pacientes asintomáticos con ERC estadios 1-5 y anemia que presentaban un test inmunoquímico cualitativo de sangre oculta en heces positivo. Resultados: Se analizaron 9.658 pacientes con ERC, de los que 286 (2,9%) presentaban anemia; 198 tuvieron un test de sangre oculta en heces positivo (47% varones, 71,1 ± 11,8 años). El estudio endoscópico reveló 255 lesiones, con al menos una lesión en el 68,2%, siendo las más prevalentes: pólipos colorrectales adenomatosos (39,6%), lesiones agudas de la mucosa gástrica (22,6%), lesiones neoplásicas (15,1%), angiodisplasias (14,4%), esofagitis (8,4%), enfermedad inflamatoria intestinal (4,8%) y colitis isquémica (3,1%). La uremia y el ácido acetilsalicílico fueron identificados como factores de riesgo de lesiones agudas de la mucosa gástrica. Las angiodisplasias se relacionaron con el enolismo, el mayor estadio de ERC, la anemia y la ausencia de respuesta a agentes estimulantes de la eritropoyesis. La edad y la anemia refractaria constituyeron factores de riesgo de pólipos adenomatosos y cáncer colorrectal. Conclusión: Los pacientes renales con anemia podrían beneficiarse de un estudio endoscópico debido a la alta prevalencia de lesiones gastrointestinales que presentan, particularmente pólipos adenomatosos y cáncer colorrectal, más frecuentes en los mayores de 50 años con ERC estadios 3-5

Introduction: Despite the frequency with which anaemia is present in patients with chronic kidney disease (CKD), its relationship with gastrointestinal lesions has not been studied. Method: A cross-sectional, analytical, observational study involving one year of recruitment was carried out to determine the prevalence of endoscopic gastrointestinal lesions and associated risk factors in asymptomatic patients with chronic kidney disease stages 1-5 and anaemia who had a positive qualitative immunochemical faecal occult blood test. Results: A total of 9,658 patients with CKD were analysed, of which 286 (2.9%) had anaemia; 198 had a positive faecal occult blood test (47% male, 71.1 ± 11.8 years). The endoscopic study revealed 255 lesions, with at least one lesion in 68.2% of patients, with the most prevalent being: adenomatous colorectal polyps (39.6%), acute lesions of the gastric mucosa (22.6%), neoplastic lesions 15.1%), angiodysplasia (14.4%), oesophagitis (8.4%), inflammatory bowel disease (4.8%) and ischaemic colitis (3.1%). Uraemia and acetylsalicylic acid were identified as risk factors for acute gastric mucosal lesions. Angiodysplasia was associated with alcoholism, a more advanced stage of chronic kidney disease, anaemia, and lack of response to erythropoiesis-stimulating agents. Age and refractory anaemia were risk factors for adenomatous polyps and colorectal cancer. Conclusion: Renal patients with anaemia could benefit from an endoscopic study due to their high prevalence of gastrointestinal lesions, particularly adenomatous polyps and colorectal cancer, which are more common in those over 50 years of age with CKD stages 3-5

Pancreatic stents in ERCP. Where are we?

Post-ERCP pancreatitis (PEP) is a common complication most feared by endoscopists. Incidence ranges widelly from 2.1% to 24.4%, which results from patient heterogeneity and differences in endoscopist expertise, method, PEP definition, and severity. Pathophysiology is multifactorial, and involves a combination of chemical, thermal, mechanical, hydrostatic, enzymatic, allergic, and microbiological factors resulting from papillary instrumentation and/or contrast administration within the pancreatic duct (volume and osmolarity). Even genetic abnormalities may represent a risk factor, as is the case with homozygous alpha-1-antitrypsin deficiency, which leads to an increase in hemorrhagic PEP rates.

Is the education available to anesthetists adequate to provide sedation in endoscopy units?

It is a letter that aims to emphasize the type of sedation that is sometimes used by anesthetists to perform a standard endoscopy and the excessive use of the operating room, which increases the cost of endoscopy and reduces the resources of surgical time.

A Scoring System to Determine Risk of Delayed Bleeding After Endoscopic Mucosal Resection of Large Colorectal Lesions.

BACKGROUND & AIMS: After endoscopic mucosal resection (EMR) of colorectal lesions, delayed bleeding is the most common serious complication, but there are no guidelines for its prevention. We aimed to identify risk factors associated with delayed bleeding that required medical attention after discharge until day 15 and develop a scoring system to identify patients at risk. METHODS: We performed a prospective study of 1214 consecutive patients with nonpedunculated colorectal lesions 20 mm or larger treated by EMR (n = 1255) at 23 hospitals in Spain, from February 2013 through February 2015. Patients were examined 15 days after the procedure, and medical data were collected. We used the data to create a delayed bleeding scoring system, and assigned a weight to each risk factor based on the ß parameter from multivariate logistic regression analysis. Patients were classified as being at low, average, or high risk for delayed bleeding. RESULTS: Delayed bleeding occurred in 46 cases (3.7%, 95% confidence interval, 2.7%-4.9%). In multivariate analysis, factors associated with delayed bleeding included age ≥75 years (odds ratio [OR], 2.36; P < .01), American Society of Anesthesiologist classification scores of III or IV (OR, 1.90; P ≤ .05), aspirin use during EMR (OR, 3.16; P < .05), right-sided lesions (OR, 4.86; P < .01), lesion size ≥40 mm (OR, 1.91; P ≤ .05), and a mucosal gap not closed by hemoclips (OR, 3.63; P ≤ .01). We developed a risk scoring system based on these 6 variables that assigned patients to the low-risk (score, 0-3), average-risk (score, 4-7), or high-risk (score, 8-10) categories with a receiver operating characteristic curve of 0.77 (95% confidence interval, 0.70-0.83). In these groups, the probabilities of delayed bleeding were 0.6%, 5.5%, and 40%, respectively. CONCLUSIONS: The risk of delayed bleeding after EMR of large colorectal lesions is 3.7%. We developed a risk scoring system based on 6 factors that determined the risk for delayed bleeding (receiver operating characteristic curve, 0.77). The factors most strongly associated with delayed bleeding were right-sided lesions, aspirin use, and mucosal defects not closed by hemoclips. Patients considered to be high risk (score, 8-10) had a 40% probability of delayed bleeding.

Radiofrequency ablation for the treatment of radiation proctitis.

BACKGROUND AND STUDY AIMS: The main endoscopic therapy for radiation proctitis is argon plasma coagulation (APC); however treatment is not always successful. Radiofrequency ablation (RFA) is a possible treatment for radiation proctitis but data are scarce. The aim of this study was to report on the safety and efficacy of RFA in the treatment of radiation proctitis. PATIENTS AND METHODS: This study was an open-label, retrospective, multicenter study of patients with chronic hemorrhagic radiation proctitis who were treated with RFA. Data included a three-item symptom score, the number of packed red blood cell transfusions, the lowest hemoglobin concentration, and complications, during the 6 months prior to and after RFA. Clinical success was defined as a decrease in the symptom score. Biological success was defined as an increase in the hemoglobin rate with equal or decreased number of transfusions required. RESULTS: A total of 17 patients underwent a median of 2 RFA sessions (range 1 - 4), without perioperative complications. Symptom scores decreased in 16 patients (clinical success 94 %), from a mean score of 3.6 (median 4) to 1.4 (median 1) (P < 0.01). Two patients developed rectal ulceration, with no local symptoms. During the 6 months after RFA, hemoglobin concentration increased in all 17 patients (from mean 8.3 ± 2.8 g/dL [median 7.5] to 11.3 ± 2.2 g/dL [median 11.0]; P < 0.01). Among 13 patients who were transfusion dependent prior to RFA (mean 7.2 ± 7.7 transfusions [median 4]), 9 patients (69 %) were weaned off transfusions after RFA. A significant increase in the hemoglobin level was observed in this subgroup of patients (from mean 7.2 ± 1.4 g/dL [median 7.3] to 10.7 ± 1.5 g/dL [median 10.5]; P < 0.001). Biological success was 100 %. CONCLUSIONS: RFA seems to significantly decrease clinical symptoms and increase the hemoglobin concentration, thus reducing the need for transfusions.

Radiofrequency ablation for the treatment of gastric antral vascular ectasia.

BACKGROUND AND STUDY AIMS: The traditional endoscopic treatment for gastric antral vascular ectasia (GAVE) is argon plasma coagulation, but results are not always positive. Radiofrequency ablation (RFA) is a new endoscopic therapy that may be an attractive option for the treatment of GAVE. The aim of this study was to assess the efficacy and safety of RFA for the treatment of GAVE. PATIENTS AND METHODS: This was an open-label, retrospective, case series study. The main outcome measures were number of red blood cell (RBC) packs transfused (transfusion requirement) and hemoglobin concentrations (g/dL) in the 6 months prior to and after RFA. Success was defined as a decrease in transfusion requirement in the 6 months after RFA compared with before treatment. RESULTS: A total of 24 patients underwent a mean of 1.8 ± 0.8 RFA sessions. No complications were reported. One patient was referred for additional argon plasma coagulation during follow-up. The mean number of RBC packs decreased in all 23 transfusion-dependent patients, from a mean of 10.6 ± 12.1 during the 6 months prior to RFA, to a mean of 2.5 ± 5.9 during the 6 months after RFA treatment (P < 0.001), and 15 patients (65.2 %) were weaned off transfusions completely. An increase in the hemoglobin concentration was reported in all patients after RFA (from 6.8 ± 1.4 g/dL to 9.8 ± 1.8 g/dL; P < 0.001). CONCLUSION: RFA for the treatment of GAVE seems feasible and safe, and significantly reduced the need for RBC transfusion and increased the hemoglobin level in this retrospective case series.

Exocrine pancreatic insufficiency and chronic pancreatitis in chronic alcoholic liver disease: coincidence or shared toxicity?

OBJECTIVES: The aims of this study were to determine the prevalence of exocrine pancreatic insufficiency (EPI) and chronic pancreatitis (CP) in patients with chronic alcoholic liver disease and to analyze the possible associated factors. METHODS: This is an analytical observational study of cases and controls for a sample of patients with chronic alcoholic and nonalcoholic liver disease. Exocrine pancreatic insufficiency was diagnosed using the C mixed-triglyceride breath test. Patients with abdominal pain underwent endoscopic ultrasonography for CP evaluation using the Wiersema criteria. RESULTS: A total of 154 patients were included, 129 with alcoholic liver disease (83 with cirrhosis) and 25 with nonalcoholic liver disease. Exocrine pancreatic insufficiency was found in 55.2% versus 16.7% (P < 0.001), 70% of patients without cirrhosis compared with 46.2% of patients with cirrhosis had pancreatic insufficiency (P = 0.017), and 82.7% of patients with alcoholic liver disease and abdominal pain had CP (P < 0.001). Exocrine pancreatic insufficiency was associated with the male sex, alcohol intake, abdominal pain, degree of liver failure, and the absence of portal hypertension. Chronic pancreatitis was correlated with age younger than 55 years and abdominal pain. CONCLUSIONS: Patients with alcoholic liver disease had a high prevalence of EPI and CP; this prevalence was even higher in patients who have not yet developed cirrhosis with liver failure or portal hypertension.
