Four-dimensional impedance manometry volume metrics for predicting abnormal bolus retention.

BACKGROUND: The objective measurement for esophageal bolus volume and bolus clearance could classify abnormal high-resolution manometry (HRM) beyond the current Chicago classification. We aimed to compare the novel four-dimensional impedance manometry (4D HRM) volume metrics with timed barium esophagram (TBE). METHODS: Adults with esophageal symptoms undergoing HRM and TBE were included. A custom-built program for 4D HRM analysis measured esophageal luminal cross-sectional area (CSA) from impedance and subsequently derived esophageal bolus volume and clearance. 4D HRM volume metrics included pre-swallow residual volume, maximal volume, retention volume, and clearance ratio defined as 1.0-retention volume divided by the maximal volume. An abnormal TBE was defined as a column height >5 cm at 1 min or 5 min. KEY RESULTS: A total of 95 patients (normal motility: 33%; ineffective esophageal motility: 12%; absent contractility: 10%; esophagogastric junction outflow obstruction: 30%; type I achalasia: 5%; type II achalasia: 12%) were categorized into normal TBE (58%), abnormal TBE at 1 min (17%), and abnormal TBE at 5 min (25%). The AUROC demonstrated that, among all 4D HRM volume metrics, the clearance ratio had the best performance in predicting abnormal TBE at 5 min (AUROC, 95% confidence interval: 0.89, 0.82-0.96), and exhibited a strong negative correlation with TBE at 5 min (r = -0.65; p < 0.001). CONCLUSIONS & INFERENCES: Novel 4D HRM volume metrics provide objective measurement of esophageal bolus volume and bolus clearance. The clearance ratio has a strong correlation with TBE and could potentially serve as a substitute for TBE to measure esophageal retention.

The Severity of Reduced Esophageal Distensibility Parallels Eosinophilic Esophagitis Disease Duration.

BACKGROUND & AIMS: Chronic inflammation of eosinophilic esophagitis (EoE) results in progressive, fibrostenotic remodeling of the esophageal wall. This study aimed to demonstrate objective changes in esophageal distensibility relative to duration of EoE disease using a functional lumen imaging probe (FLIP). METHODS: Adult patients with EoE who completed a 16-cm FLIP protocol during endoscopy were evaluated in a cross-sectional study. FLIP analysis focused on distensibility plateau (DP) of the esophageal body. The time from onset of symptoms to time of endoscopy with FLIP was assessed, as was time from symptom onset to EoE diagnosis (ie, diagnostic delay). RESULTS: A total of 171 patients (mean age 38 ± 12 years; 31% female) were included; the median symptom duration was 8 (interquartile range, 3-15) years and diagnostic delay was 4 (interquartile range, 1-12) years. At the time of endoscopy with FLIP, there were 54 patients (39%) in histologic remission (<15 eosinophils per high-power field [eos/hpf]). Symptom duration and diagnostic delay were negatively correlated with DP (rho = -0.326 and -0.309; P values < .001). Abnormal esophageal distensibility (DP ≤17 mm) was more prevalent with increased duration of symptoms (P < .004): 23% at <5 years to 64% at ≥25 years. When stratifying the cohort based on mucosal eosinophil density, patients with ≥15 eos/hpf had significantly lower DP with greater symptom duration (P = .004), while there was not a significant difference among patients with <15 eos/hpf (P = .060). CONCLUSIONS: Esophageal distensibility objectively measured with FLIP was reduced in EoE patients with greater symptom duration and diagnostic delay. This supports that EoE is a progressive, fibrostenotic disease and that FLIP may be a useful tool to monitor disease progression in EoE.

Composite score of physiomechanical esophageal function using functional lumen imaging probe panometry in eosinophilic esophagitis.

BACKGROUND AND AIMS: The evaluation provided by functional lumen imaging probe (FLIP) panometry includes esophageal distensibility/compliance (mechanics) of the esophageal body and esophagogastric junction (EGJ) and esophageal motility (secondary peristalsis). We developed a composite score using these parameters to characterize physiomechanical function in patients with eosinophilic esophagitis (EoE). METHODS: Two hundred fifteen adult patients with EoE who completed FLIP panometry during sedated endoscopy with esophageal biopsy sampling were included. FLIP metrics of esophageal body Compliance, Contractile response, Distensibility plateau, and maximum EGJ Diameter (C2D2) were scored as 0 for normal versus 1 or 2 for increasing degree of abnormality. Scores were summed to calculate the composite C2D2 score. RESULTS: The C2D2 score had a significant positive correlation with mucosal eosinophil count (ρ = .241) and total Endoscopic EoE Reference Score (ρ = .467). Among 46 patients off treatment at the baseline evaluation, future proton pump inhibitor (PPI) responders (ie, achieved mucosal eosinophil count <15 per high-powered field after PPI treatment) had lower C2D2 scores than PPI nonresponders (median, 2 [interquartile range, 1-3] vs 4 [interquartile range, 2-6], respectively; P = .003). A regression model (that controlled for age, sex, and baseline eosinophil count) showed a C2D2 score ≤3 had an odds ratio of 14.5 (95% confidence interval, 2.6-85) to predict future PPI response. However, total Endoscopic EoE Reference Scores (P = .142) and baseline eosinophil count (P = .480) did not differ between PPI responders and PPI nonresponders. CONCLUSIONS: This composite score of FLIP panometry metrics, the C2D2 score, may facilitate characterizing physiomechanical function in EoE and serve as an objective outcome measure.

Assessing mechanical function of peristalsis with functional lumen imaging probe panometry: Contraction power and displaced volume.

BACKGROUND AND AIMS: The distal contractile integral (DCI) quantifies the contractile vigor of primary peristalsis on high-resolution manometry (HRM), whereas no such metric exists for secondary peristalsis on functional lumen imaging probe (FLIP) panometry. This study aimed to evaluate novel FLIP metrics of contraction power and displaced volume in asymptomatic controls and a patient cohort. METHODS: Thirty-five asymptomatic controls and adult patients (with normal esophagogastric junction outflow/opening and without spasm) who completed HRM and FLIP panometry were included. The patient group also completed timed barium esophagram (TBE). Contraction power (estimate of esophageal work over time) and displaced volume (estimate of contraction-associated fluid flow) were computed from FLIP. HRM was analyzed per Chicago Classification v4.0. KEY RESULTS: In controls, median (5th-95th percentile) contraction power was 27 mW (10-44) and displaced volume was 43 mL (17-66). 95 patients were included: 72% with normal motility on HRM, 17% with ineffective esophageal motility (IEM), and 12% with absent contractility. Among patients, DCI was significantly correlated with both contraction power (rho = 0.499) and displaced volume (rho = 0.342); p values < 0.001. Both contraction power and displaced volume were greater in patients with normal motility versus IEM or absent contractility, complete versus incomplete bolus transit, and normal versus abnormal retention on TBE; p values < 0.02. CONCLUSIONS: FLIP panometry metrics of contraction power and displaced volume appeared to effectively quantify peristaltic vigor. These novel metrics may enhance evaluation of esophageal motility with FLIP panometry and provide a reliable surrogate to DCI on HRM.

A PhysioMechanical Model of Esophageal Function in Eosinophilic Esophagitis.

BACKGROUND & AIMS: Eosinophilic esophagitis (EoE) is characterized by eosinophilic inflammation, but also heterogeneous presentations involving fibrostenotic esophageal remodeling and esophageal dysmotility. We aimed to define and evaluate phenotypes of EoE using functional lumen imaging probe (FLIP) panometry (ie, a PhysioMechanical classification of EoE). METHODS: Patients with EoE who completed FLIP during endoscopy were included in a cross-sectional study. FLIP studies were analyzed for distensibility plateau and compliance of the esophageal body, maximum esophagogastric junction diameter, and contractile response pattern. These FLIP features were then applied to define PhysioMechanical classifications. RESULTS: A total of 215 patients with EoE (mean [standard deviation] age 38 [12] years; 31% female) were included. Seven PhysioMechanical classifications were identified that differed by various clinical characteristics, including symptom duration (P < .001) and Endoscopic EoE Reference Scores (EREFS) (P < .001). In particular, patients with "nonreactive fibrostenosis" (n = 14), had greater symptom duration (median [interquartile range] 20 [10-30] years) and more frequently had EREFS grade 2 or 3 ring scores (14 of 14 patients) than patients with a "normal" PhysioMechanical classification (symptom duration: 3 [1-8] years; 4 of 50 [8%] had EREFS grade 2 or 3 rings). In addition, among patients off treatment at cross-sectional evaluation (n = 46), there was a difference between PhysioMechanical classifications in future proton pump inhibitor (PPI) response rates (ie, achieving peak mucosal eosinophil count <15 per high-powered field after PPI treatment); P = .009. PPI response ranged from 87% (13 of 15 patients) with "isolated esophagogastric junction outflow obstruction" to 11% (1 of 9 patients) with "spastic-reactive fibrostenosis." CONCLUSIONS: Classifying PhysioMechanical esophageal function in EoE based on FLIP panometry features may facilitate defining disease severity and directing management in EoE.

Benefit of extending the protocol for high resolution manometry according to the version 4.0 of the Chicago criteria. A multicenter study.

BACKGROUND: The last version of the Chicago Criteria for high resolution esophageal manometry proposes an expanded protocol including complementary maneuvers to improve the diagnostic yield of the exploration. Our aim was to determine the diagnostic gain of the CCv4.0 protocol compared to the CCv3.0 protocol. METHODS: All manometry recordings performed in 4 reference centers during the first 10 months after the implementation of the new protocol were retrospectively reviewed. The time spent to complete the protocol was measured, and the changes in diagnosis resulting from the new CCv4.0 were compared to CCv3.0. KEY RESULTS: From a total of 756 HRM performed, 606 studies could be properly analyzed. The duration of the studies was 18.3 ± 4.3 min. From these, 11.3 ± 3.4 min were spent to complete the CCv3.0 protocol, and 7.4 ± 3.6 min were spent for the remaining maneuvers. A discordant diagnosis between CCv3.0 and CCv4.0 was obtained in 12% of patients: 32% of patients with ineffective esophageal motility turned to normal motility; 24% of patients with esophagogastric junction outlet obstruction (EGJOO) turned to a non-obstructive disorder; and 1% of patients with an apparently normal EGJ relaxation, turned to an obstructive disorder. EGJOO according to CCv4.0 was more prevalent in patients referred for dysphagia (11%) than those referred for GERD (4%; p = 0.003). CONCLUSIONS AND INFERENCES: Prolongation of the time spent to complete the CCv4.0 protocol leads to a change in the diagnosis of 12% of patients. Clinically relevant changes are mainly related to the evaluation of EGJOO.

Motorized Spiral Enteroscopy Is Effective in Patients with Prior Abdominal Surgery.

BACKGROUND: Motorized Spiral Enteroscopy (MSE) reduces procedure time and increases insertion depth into the small bowel; however, there is scarce evidence on factors affecting MSE efficacy. AIMS: To evaluate diagnostic yield and adverse events of MSE including patients with prior major abdominal surgery. METHODS: A prospective observational study was conducted on patients undergoing MSE from June 2019 to December 2021. Demographic characteristics, procedure time, depth of maximum insertion (DMI), technical success, diagnostic yield, and adverse events were collected. RESULTS: Seventy-four anterograde (54.4%) and 62 retrograde (45.6%) enteroscopies were performed in 117 patients (64 males, median age 67 years). Fifty patients (42.7%) had prior major abdominal surgery. Technical success was 91.9% for anterograde and 90.3% for retrograde route. Diagnostic yield was 71.6% and 61.3%, respectively. The median DMI was 415 cm (264-585) for anterograde and 120 cm (37-225) for retrograde enteroscopy. In patients with prior major abdominal surgery, MSE showed significantly longer small bowel insertion time (38 vs 29 min, p = 0.004), with similar diagnostic yield (61 vs 71.4%, p = 0.201) and DMI (315 vs 204 cm, p = 0.226). The overall adverse event rate was 10.3% (SAE 1.5%), with no differences related to prior abdominal surgery (p = 0.598). Patients with prior surgeries directly involving the gastrointestinal tract showed lower DMI (189 vs 374 cm, p = 0.019) with equal exploration time (37.5 vs 38 min, p = 0.642) compared to those with other abdominal surgeries. CONCLUSIONS: MSE is effective and safe in patients with major abdominal surgery, although longer procedure times were observed. A lower depth of insertion was detected in patients with gastrointestinal surgery.

Performance of a new flexible 19 G EUS needle in pancreatic solid lesions located in the head and uncinate process: A prospective multicenter study.

Background and study aims The poor flexibility of large-bore EUS needles often leads to technical failure when sampling from the duodenum. The aim of this study was to evaluate the technical and diagnostic performances of a new Menghini tip 19G nitinol EUS needle for sampling pancreatic solid lesions in the head and uncinate process. Patients and methods This was a European prospective multicenter single-arm study. A maximum of four passes were allowed. In case of failure, different needles were permitted. Results We included 75 patients (51 % males) with lesions in the head (n = 68; 91 %) and uncinate process (n = 7; 9 %) (mean size: 33 ±â€Š12 mm; number of passes: 1.8 ±â€Š0.9). Technical success was seen in 71 of 75 (94.7 %). Diagnostic rates were 89.3 % (67/75) and 94.4 % (67/71) in the intention-to-treat (ITT) and per-protocol (PP) analysis, respectively. In the eight cases with failure, diagnosis was obtained with another needle (n = 4), from another lesion (n = 3) or with follow-up (n = 1). A histological sample was obtained in 64 patients (ITT 85.3 % and PP 90 %) and immunohistochemistry was successfully performed in 13 of 15 lesions in which it was required. No differences between rapid on-site evaluation (ROSE) and non-ROSE groups were observed regarding diagnostic success (87.5 % vs 91 %, P  = 0.582) and diagnosis at the first pass (70 % vs 81 %, P  = 0.289). Number of passes was lower in the ROSE group (1.4 + 0.9 vs 2.2 + 0.7, P  < 0.001). One adverse event was recorded (1.3 %) consisting in a duodenal perforation after a single session EUS-ERCP. Conclusions The new nitinol Menghini tip 19G EUS needle showed high technical diagnostic success in safely sampling solid lesions in the head and uncinate process of the pancreas.

Diagnostic yield of adding solid food swallows during high-resolution manometry in esophageal motility disorders.

BACKGROUND: High-resolution manometry (HRM) is a key method to evaluate esophageal motility disorders. Current evaluation is usually performed with single water swallows (SWS) that may not challenge esophageal function or reproduce symptoms. Solid food swallows (SFS) could increase the diagnostic yield for clinically relevant disorders. METHODS: Patients with dysphagia referred for esophageal HRM during a 2-year period in a single center were reviewed retrospectively and included if SFS was performed during HRM. Chicago classification v3.0 was used to define esophageal motility disorders. KEY RESULTS: One hundred and four patients with dysphagia were included (59% women, mean age 57 years). Ineffective esophageal motility was the most frequent motility disorder. Compared to SWS, the diagnosis changed after SFS in 33 patients (31.7%) including a change from normal or minor diagnosis toward major motility disorders in 14 (13.4%). Fifteen subjects (14.4%) shifted from a minor disorder on SWS to normal after SFS. SFS changed the diagnosis in 53.8% of patients with previous surgery versus 29.5% of those without (p = 0.023). Pressurization during rapid drink challenge was more frequent when SFS changed the diagnosis to major motility disorders (69.2% vs. 37.3%, p = 0.033). Twenty-nine percent of patients reported symptoms during SFS, mostly those with diagnostic change to major disorders after SFS (71.4% of patients with changes to major disorders vs. 22.2% of patients without, p < 0.0001). CONCLUSION & INFERENCES: Solid food swallows is a simple way to improve the diagnostic yield of HRM in patients with dysphagia and should be added to manometry protocol in daily clinical practice.

Radiation-induced damage in the lower gastrointestinal tract: Clinical presentation, diagnostic tests and treatment options.

Radiation therapy is an important ally when treating malignant lesions in the pelvic area, but it is not exempt of adverse events. There are some measures that can be taken to reduce the possibility of these effects, but some are non-modifiable factors related to previous treatments, location of the lesions or comorbidities. There is a wide variety of clinical presentations that can be of an acute or chronic onset that go from mild to severe forms or that can have a great impact in the quality of life. Medical available therapies as metronidazole, sucralfate, mesalizine or probiotics, can be of aid although some lack of solid evidence of efficacy. Endoscopic treatment can be performed with argon plasma coagulation, bipolar cautery, radiofrequency, laser therapy or dilation. Hyperbaric therapy can be applied in refractory cases and surgery must be reserved to selected patients due to its high morbidity and mortality.

Evaluación del cumplimiento a largo plazo de los indicadores de calidad en la esofagogastroduodenoscopia / Evaluation of long-term adherence to oesophagogastroduodenoscopy quality indicators

INTRODUCCIÓN: En un estudio previo demostramos que un pequeño programa de formación mejoraba los indicadores de calidad de la esofagogastroduodenoscopia (EGD) que llegaban a los estándares recomendados. Sin embargo, desconocemos el efecto de esta formación a largo plazo. El objetivo de este estudio fue valorar la calidad de las EGD después de 3años de haber realizado un programa de mejora. MATERIAL Y MÉTODOS: Estudio comparativo de 2 cohortes: EGD posteriores a un programa de formación realizado en 2016 (grupo A) y EGD en enero-marzo de 2019 (grupo B). El grupo B se dividió en 2 subgrupos: endoscopistas que habían participado en el programa de formación previo (B1) y los que no (B2). Se utilizaron los indicadores de calidad intraprocedimiento recomendados por la ASGE-ACG. RESULTADOS: Se analizaron un total de 1.236 EGD, 600 en el grupo A y 636 en el B (439 subgrupo B1 y 197 subgrupo B2). El número de exploraciones completas fue inferior en el grupo B (566 [94,3%] vs. 551 [86,6%]; p < 0,001). Se observó una disminución significativa en prácticamente todos los indicadores de calidad que, además, no alcanzaron los estándares recomendados: retroversión gástrica (96% vs. 81%; p < 0,001); protocolo de biopsias de Seattle (86% vs. 50%; p = 0,03), descripción de la lesión en la hemorragia (100% vs. 62%; p < 0,01), toma de ≥4 biopsias en sospecha de celiaquía (92,5% vs. 18%; p < 0,001), fotodocumentación de lesión (94% vs. 90%; p < 0,05). Cuando consideramos el global de la prueba (incluyendo la actuación correcta y la fotodocumentación adecuada), también se observó una disminución significativa (90,5% vs. 62%; p < 0,001). No hubo diferencias entre los subgrupos B1 y B2. CONCLUSIONES: La mejora observada en 2016 tras un programa de formación no perdura a los 3años. Es necesario hacer programas de formación continuados para mantener la calidad de la EGD por encima de los estándares recomendados

INTRODUCTION: In a previous study we demonstrated that a simple training programme improved quality indicators of Oesophagogastroduodenoscopy (OGD) achieving the recommended benchmarks. However, the long-term effect of this intervention is unknown. The aim of this study was to assess the quality of OGDs performed 3 years after of having completed a training programme. MATERIAL AND METHODS: A comparative study of 2 cohorts was designed as follows: Group A included OGDs performed in 2016 promptly after a training programme and Group B with OGDs performed from January to March 2019, this group was also divided into 2 subgroups: subgroup B1 of Endoscopists who had participated in the previous training programme and subgroup B2 of Endoscopists who had not. The intra-procedure quality indicators proposed by ASGE-ACG were used. RESULTS: A total of 1236 OGDs were analysed, 600 from Group A and 636 from Group B (439 subgroup B1 and 197 subgroup B2). The number of complete examinations was lower in Group B (566 [94.3%] vs. 551 [86.6%]; p < 0.001). A significant decrease was observed in nearly all quality indicators and they did not reach the recommended benchmarks: retroflexion in the stomach (96% vs. 81%; p < 0.001); Seattle biopsy protocol (86% vs. 50%; p = 0.03), description of the upper GI bleeding lesion (100% vs. 62%; p < 0.01), sufficient intestinal biopsy specimens (at least 4) in suspected coeliac disease (92.5% vs. 18%; p < 0.001), photo documentation of the lesion (94% vs. 90%; p < 0.05). Regarding the overall assessment of the procedure (including correct performance and adequate photo documentation), a significant decrease was also observed (90.5% vs. 62%; p < 0.001). There were no differences between subgroups B1 and B2. CONCLUSIONS: The improvement observed in 2016 after a training programme did not prevail after 3 years. In order to keep the quality of OGDs above the recommended benchmarks, it is necessary to implement continuous training programmes

Comparison of Capsule Endoscopy and Magnetic Resonance Enterography for the Assessment of Small Bowel Lesions in Crohn's Disease.

Background and Aims: Diagnostic yield of Small Bowel Capsule Endoscopy (SBCE) for the assessment of small bowel (SB) lesions is higher than radiologic imaging techniques. However, magnetic resonance enterography (MRE) data are scarce and inconclusive. Colon Capsule Endoscopy (CCE) is a new capsule modality. The primary aim of our study was to compare MRE and capsule endoscopy (CE) for the assessment of Crohn's disease (CD). The secondary objectives were to compare the diagnostic accuracy of both CE modalities and changes in Montreal classification after each examination. Methods: We included 47 patients with established (n = 32) or suspected CD (n = 15). MRE was performed first to rule out strictures. In patients with a suspected stricture by MRE, an Agile Patency Capsule was performed. SB disease activity was measured by MaRIA score (MRE) and Lewis Index (CE). Results: SB lesions were found in 36 of47 patients with CE and in 21 of47 patients with MRE (76.6% vs 44.7%, P = 0.001). Jejunal inflammation was detected by CE in 31.9% of patients and by MRE in 6.4% of patients (15/47 vs 3/47; P = 0.03); lesions in ileum were detected in 57.4% of patients by CE, and in 21.3% of patients by MRE (27/ 47 vs 10/ 47; P = 0.04). Finally, in terminal ileum, CE showed lesions in 68.1% (32/47) of patients, whereas MRE detected lesions in 38.3% (18/ 47 patients), (P = 0.001). The original Montreal classification was changed in 53.1% of patients (25/ 47) based on CE findings and in 12.7% of patients (6/47) based on MRE findings (P < 0.05). Conclusions: In our cohort CE was significantly superior to MRE for detecting SB lesions, mainly superficial and proximal lesions. CE is useful for a appropriate patients' classification according to Montreal classification.

Indicadores de calidad en la esofagogastroduodenoscopia: estudio comparativo de los resultados tras un programa de mejora en un hospital terciario / Quality indicators for esophagogastroduodenoscopy: A comparative study of outcomes after an improvement programme in a tertiary hospital

Introducción: El registro y la medición de los indicadores de calidad suponen una oportunidad de mejora. Sin embargo, no existen experiencias previas en nuestro medio sobre su cumplimiento en la esofagogastroduodenoscopia (EGD). Objetivo: Analizar el cumplimiento de los criterios de calidad de las EGD y evaluar la mejora tras la realización de un programa de formación. Pacientes y métodos Estudio comparativo de 2 cohortes: una, retrospectiva (grupo control) y otra, prospectiva (grupo intervención), antes y después de un programa de formación que consistió en una sesión informativa y la mejora del programa de elaboración de informes. Se utilizaron los indicadores de calidad propuestos por la American Society for Gastrointestinal Endoscopy y el American College of Gastroenterology. Resultados: Se incluyeron un total de 1.200 EGD de forma secuencial (600 en cada grupo). Tras el programa de formación se observó una mejoría significativa en los siguientes indicadores: indicación documentada (93 vs. 99,8%; p<0,01), exploraciones completas documentadas (94,7 vs. 97,3%; p<0,01), actuación correcta (63,7 vs. 87,9%; p<0,01), toma adecuada de biopsias según protocolos (57,9 vs. 83,8%; p<0,01), fotodocumentación de lesiones descritas (84,1 vs. 94,9%; p<0,01], fotodocumentación por segmentos (52,9 vs. 70,5%; p<0,01) y valoración global correcta (56,9 vs. 90,5%; p<0,01). La toma de biopsias para celiaquía, la indicación documentada, la exploración completa y la actuación correcta, si procedía, consiguieron superar el estándar recomendado. Conclusión: Un programa de formación muy sencillo mejora los indicadores de calidad de la EGD, alcanzando la mayoría los estándares recomendados por la American Society for Gastrointestinal Endoscopy y el American College of Gastroenterology (AU)

Introduction: There is an opportunity for improvement in the recording and measuring of quality indicators. However, no previous experiences exist in our field in terms of their compliance in esophagogastroduodenoscopy (EGD). Objective: To analyse compliance with EGD quality criteria and evaluate improvement after conducting a training programme. Patients and methods: Comparative study of 2 cohorts: one retrospective (control group) and one prospective (intervention group), before and after a training programme consisting of an information session and the report writing improvement programme. The quality indicators proposed by the American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology were used. Results: A total of 1,200 EGDs were included in a sequential manner (600 in each group). Following the training programme, a significant improvement was observed in the following indicators: documented indication (93 vs. 99.8%; P<0.01), documented full examinations (94.7 vs. 97.3%; P<0.01), correct performance (63.7 vs. 87.9%; P<0.01), appropriate biopsies according to protocols (57.9 vs. 83.8%; P<0.01), photo-documentation of described lesions (84.1 vs. 94.9%; P<0.01), photo-documentation per segment (52.9 vs. 70.5%; P<0.01) and correct overall assessment (56,9 vs. 90.5%; P<0.01). Biopsies for coeliac disease, documented indication, full examination and correct performance, if it went ahead, exceeded the recommended standard. Conclusion: A very simple training programme improves EGD quality indicators, with the majority reaching the standards recommended by the American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology (AU)

Endoscopic ultrasonography can avoid unnecessary laparotomies in patients with pancreatic adenocarcinoma and undetected peritoneal carcinomatosis.

BACKGROUND/OBJECTIVE: To assess the relationship between the presence of ascites detected by endoscopic ultrasonography (EUS) and peritoneal carcinomatosis (PC) in patients with pancreatic adenocarcinoma. METHODS: Consecutive patients who underwent a EUS for preoperative staging of a pancreatic adenocarcinoma between 1998 and 2014 were retrospectively reviewed. The diagnosis of PC was confirmed by histopathology or peritoneal fluid cytology. The main outcome of the study was the relationship of ascites at EUS and PC in patients with pancreatic cancer. Secondarily, to evaluate the relationship between this finding and survival as well as the development of PC during follow-up. RESULTS: A total of 136 patients were included: 30 patients with local unresectable tumor or metastatic disease and 106 potentially-resectable candidates based on CT staging. EUS showed ascites in 27 (20%) patients, of whom 8 (29.6%) had PC. The sensitivity, specificity, PPV, NPV and accuracy of ascites by EUS in the detection of PC in this group of patients were 67%, 85%, 30%, 96% and 83%, respectively. Ascites detected by EUS was the only independent predictive factor of PC with an OR of 11 (CI 95%: 3-40). The detection of ascites by EUS was associated with a shorter survival (median survival time 7,3 months; range 0-60 vs 14.2 months; range 0-140) (p = 0.018) and earlier development of PC during follow-up (median 3.2 months, range 1.4-18.1 vs 12.7 months, range 5.4-54.8; p = 0.003). CONCLUSION: The finding of ascites at EUS in patients with pancreatic adenocarcinoma is highly associated with PC and a poor outcome.

Quality indicators for esophagogastroduodenoscopy: A comparative study of outcomes after an improvement programme in a tertiary hospital. / Indicadores de calidad en la esofagogastroduodenoscopia: estudio comparativo de los resultados tras un programa de mejora en un hospital terciario.

INTRODUCTION: There is an opportunity for improvement in the recording and measuring of quality indicators. However, no previous experiences exist in our field in terms of their compliance in esophagogastroduodenoscopy (EGD). OBJECTIVE: To analyse compliance with EGD quality criteria and evaluate improvement after conducting a training programme. PATIENTS AND METHODS: Comparative study of 2 cohorts: one retrospective (control group) and one prospective (intervention group), before and after a training programme consisting of an information session and the report writing improvement programme. The quality indicators proposed by the American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology were used. RESULTS: A total of 1,200 EGDs were included in a sequential manner (600 in each group). Following the training programme, a significant improvement was observed in the following indicators: documented indication (93 vs. 99.8%; P<0.01), documented full examinations (94.7 vs. 97.3%; P<0.01), correct performance (63.7 vs. 87.9%; P<0.01), appropriate biopsies according to protocols (57.9 vs. 83.8%; P<0.01), photo-documentation of described lesions (84.1 vs. 94.9%; P<0.01), photo-documentation per segment (52.9 vs. 70.5%; P<0.01) and correct overall assessment (56,9 vs. 90.5%; P<0.01). Biopsies for coeliac disease, documented indication, full examination and correct performance, if it went ahead, exceeded the recommended standard. CONCLUSION: A very simple training programme improves EGD quality indicators, with the majority reaching the standards recommended by the American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology.

Accuracy of Colon Capsule Endoscopy in Detecting Colorectal Polyps in Individuals with Familial Colorectal Cancer: Could We Avoid Colonoscopies?

Background. Individuals with a family history of colorectal cancer (CRC) have an increased risk of CRC. We evaluated the diagnostic yield of CCE in the detection of lesions and also two different colon preparations. Methods. A prospective multicenter study was designed to assess CCE diagnostic yield in a cohort of asymptomatic individuals with a family history of CRC. CCE and colonoscopy were performed on the same day by 2 endoscopists who were blinded to the results of the other procedure. Results. Fifty-three participants were enrolled. The sensitivity, specificity, PPV, and NPV of CCE for detecting advanced adenomas were 100%, 98%, 67%, and 100%. Sensitivity, specificity, PPV, and NPV of CCE for the diagnosis of individuals with polyps were 87%, 97%, 93%, and 88%, respectively. CCE identify 100% of individuals with significant or advanced lesions. Overall cleanliness was adequate by 60.7% of them. The PEG-ascorbic boost seems to improve colon cleanliness, with similar colonic transit time. Conclusion. CCE is a promising tool, but it has to be considered as an alternative technique in this population in order to reduce the number of colonoscopies performed. More studies are needed to understand appropriate screening follow-up intervals and optimize the bowel preparation regimen.
