Small-bowel capsule endoscopy in patients with Meckel's diverticulum: clinical features, diagnostic workup, and findings. A European multicenter I-CARE study.

BACKGROUND AND AIMS: Meckel's diverticulum (MD) may remain silent or be associated with adverse events such as GI bleeding. The main aim of this study was to evaluate indicative small-bowel capsule endoscopy (SBCE) findings, and the secondary aim was to describe clinical presentation in patients with MD. METHODS: This retrospective European multicenter study included patients with MD undergoing SBCE from 2001 until July 2021. RESULTS: Sixty-nine patients with a confirmed MD were included. Median age was 32 years with a male-to-female ratio of approximately 3:1. GI bleeding or iron-deficiency anemia was present in nearly all patients. Mean hemoglobin was 7.63 ± 1.8 g/dL with a transfusion requirement of 52.2%. Typical capsule endoscopy (CE) findings were double lumen (n = 49 [71%]), visible entrance into the MD (n = 49 [71%]), mucosal webs (n = 30 [43.5%]), and bulges (n = 19 [27.5%]). Two or more of these findings were seen in 48 patients (69.6%). Ulcers were detected in 52.2% of patients (n = 36). In 63.8% of patients (n = 44), a combination of double lumen and visible entrance into the MD was evident, additionally revealing ulcers in 39.1% (n = 27). Mean percent SB (small bowel) transit time for the first indicative image of MD was 57% of the total SB transit time. CONCLUSIONS: Diagnosis of MD is rare and sometimes challenging, and a preoperative criterion standard does not exist. In SBCE, the most frequent findings were double-lumen sign and visible diverticular entrance, sometimes together with ulcers.

The volume of ERCP per endoscopist is associated with a higher technical success and a lower post-ERCP pancreatitis rate. A prospective analysis.

INTRODUCTION: conflicting results have been reported regarding the influence of the annual volume of endoscopic retrograde cholangiopancreatography (ERCP) on outcome. OBJECTIVE: to evaluate the influence of case volume on ERCP outcomes. PATIENTS AND METHODS: an analysis of a prospective database was performed, comparing the outcomes of ERCP in three consecutive periods defined by the number of endoscopists performing ERCP: five endoscopists in period I (P1), four in period II (P2) and three in period III (P3). Only patients with biliary ERCP in accessible and naïve papilla were included. Primary variables were cannulation rates and adverse effects (AE). The American Society of Gastrointestinal Endoscopy (ASGE) complexity grades III and IV were considered as highly complex procedures. RESULTS: a total of 2,561 patients were included: 727 (P1), 972 (P2) and 862 (P3). There were no differences in age and sex between groups (p > 0.05). The cannulation rate was significantly higher in P2 and P3: 92.4 % vs 93.3 % vs 93 % (p = 0.037). The AE rate was 13.8 %, 12.6 % and 10.3 % (p > 0.05), respectively. The rate of post-ERCP pancreatitis was significantly lower in P3: 8.5 %, 7.3 % and 5 % (p = 0.01). The rate of complex procedures was 12 %, 14.8 % and 27 % (p < 0.0001), respectively. Two endoscopists participated in all periods and only one had significantly improved outcomes. Cannulation and post-ERCP pancreatitis rates remained significantly better in P3 after adjusting for sex, complexity and endoscopist. CONCLUSION: a higher annual volume of ERCP per endoscopist was associated with a higher rate of cannulation and a lower rate of post-ERCP pancreatitis, despite the greater complexity of the procedures. These beneficial effects seem to differ between endoscopists.

El volumen de CPRE por endoscopista se asocia a mayor tasa de éxito y menor tasa de pancreatitis post-CPRE. Análisis de un registro prospectivo / The volume of ERCP per endoscopist is associated with a higher technical success and a lower post-ERCP pancreatitis rate. A prospective analysis

Introducción: la influencia del volumen anual de colangiopancreatografía retrógrada endoscópica (CPRE) en sus resultados ha sido analizada con resultados contradictorios.Objetivo: evaluar la influencia del volumen de CPRE en sus resultados. Material y métodos: análisis sobre base de datos prospectiva comparando los resultados de la CPRE en tres periodos definidos por el número de endoscopistas que la realizan: periodo I, con cinco endoscopistas; periodo II, con cuatro; y periodo III, con tres. Incluimos CPRE biliar en papila acce sible y virgen. Las variables principales fueron las tasas de canulación y los efectos adversos. Los grados de complejidad III y IV, según la clasificación de la Sociedad Americana de Endoscopia Digestiva (ASGE, por sus siglas en inglés), se consideraron procedimientos de alta complejidad. Resultados: fueron incluidos 2.561 pacientes: 727 (periodo I), 972 (periodo II) y 862 (periodo III). No hubo diferencias en edad y sexo entre grupos (p > 0,05). La tasa de canulación fue significativamente mayor en los periodos II y III: 92,4 % vs. 93,3 % vs. 93 % (p = 0,037). La tasa de efectos adver sos (EA) fue de 13,8 %, 12,6 % y 10,3 % (p > 0,05). La tasa de pancreatitis post-CPRE fue significativamente menor en el periodo III: 8,5 %, 7,3 % y 5 % (p = 0,01). El porcentaje de procedimientos de alta complejidad fue de 12 %, 14,8 % y 27 % (p < 0,0001), respectivamente. La regresión logística mostró tasas de canulación y pancreatitis post-CPRE significativamente mejores en el periodo III tras ajustar por sexo, complejidad y endoscopista. Conclusión: un mayor volumen anual de CPRE por endoscopista se asoció con mayor tasa de canulación y menor tasa de pancreatitis post-CPRE, a pesar de la mayor complejidad de los procedimientos. Estos efectos beneficiosos parecen diferir entre endoscopistas(AU)
