New management of hepatolithiasis: Can surgery be avoided? (with video).

BACKGROUND: The presence of hepatolithiasis (HL) is prevalent in eastern countries. It is a clinical entity which is rarely reported in non-surgical series because the standard treatment is the surgical option. Currently, treatment has evolved, with the use of endoscopic techniques being increased and the number of hepatectomies being decreased. SpyGlass™ is a small-calibre endoscopic direct cholangiopancreatoscopy developed to explore and perform procedures in the bile and pancreatic ducts. Single-operator peroral cholangioscopy (POC) is an endoscopic technique useful for treating difficult bile duct stones. AIMS: To assess the usefulness, efficacy, and safety of POC with the SpyGlass™ system in patients with HL. PRIMARY OBJECTIVES: to achieve technical success of the procedure and clinical success of patients with HL. STUDY DESIGN AND PATIENTS: Retrospective, single-centre cohort study of patients with HL from April 2012 to August 2018. SpyGlass™ was chosen in symptomatic patients referred from the surgery unit as the first-line procedure. To perform electrohydraulic lithotripsy (EHL), we used a Northgate Autolith IEHL generator with a 0.66-mm biliary probe. RESULTS: We performed a total of 13 procedures in 7 patients with HL. The mean age was 46 years (range 35-65) and 3/7 of patients were female. We achieved technical success in 5/7 cases (71.4%) and clinical success in 4/7 cases (57%). DISCUSSION: SpyGlass™ is safe and effective in the treatment of HL. With these results, we confirm the need for management of patients with HL in a multidisciplinary team. When the endoscopic approach is the option, this procedure must be performed by experts in advanced endoscopy.

Single-operator cholangiopancreatoscopy in pancreatobiliary diseases: clinical experience in a tertiary referral hospital.

BACKGROUND AND AIMS: to assess the usefulness, efficacy and safety of single-operator cholangiopancreatoscopy (SOCP) with the SpyGlass™ system for the management of biliopancreatic diseases. METHODS: a retrospective analysis of patients undergoing SOCP with the SpyGlass™ between September 2008 and April 2016 was performed. Data was obtained from a prospectively-maintained database at a tertiary referral center. The primary study outcomes were technical and complete endoscopic success of the procedure. Two different SpyGlass™ systems were employed; the former is called legacy and the latter, digital system (DS). RESULTS: a total of 107 SOCP procedures in 93 patients performed by a single operator were analyzed. Technical success of the SpyGlass™ examination was achieved in 90/93 (97%) of patients and complete success by resolving the biliopancreatic condition in 82/93 (88%) cases. In indeterminate biliary strictures, a complete success was achieved in 45/52 (85%) of cases. With regard to stone treatment, technical success was achieved in 34/34 (100%) patients and complete success, in 31/34 (91%) cases. Electrohydraulic lithotripsy was applied in 16/34 (47%) of cases. There were a total of 7/93 adverse effects (7.5%). CONCLUSIONS: SOCP is a useful and safe technique for the treatment of biliopancreatic diseases with a low rate of adverse effects. The procedure seems technically demanding and dedication is required.

Effect of the SARS-CoV-2 pandemic on colorectal cancer diagnosis and prognosis.

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.

[Current management of nonvariceal upper gastrointestinal bleeding in Spain]. / Situación actual del manejo de la hemorragia digestiva alta no varicosa en España.

BACKGROUND: Mortality related to nonvariceal upper gastrointestinal bleeding (NVUGIB) has not changed. More information is needed to improve the management of this entity. The aims of this study were: a) to determine the characteristics of bleeding episodes, b) to describe the clinical approaches routinely used in NVUGIB, and c) to identify adverse outcomes related to endoscopic or medical treatments in Spain. METHODS: The European survey of nonvariceal upper GI bleeding (ENERGiB) was an observational, retrospective cohort study on NVUGIB with endoscopic evaluation carried out across Europe. The present study focused on Spanish patients in the ENERGiB study. The patients were managed according to routine care. The mean and standard deviation were calculated for quantitative variables and absolute and relative frequencies were calculated for categorical variables. RESULTS: Patients (n=403) were mostly men (71%), with a mean age of 65 years, and co-morbidities (62.5%). Most of the patients were managed by gastroenterologists (57.1%) or internal medicine teams (25.1%). A proton pump inhibitor was used empirically in 80% before endoscopy. Bleeding persistence occurred in 6.4% and recurrence in 6.7%. The mortality rate at 30 days was 3.5%. CONCLUSIONS: This study contributes to the characterization of Spanish patients and NVUGIB episodes in a real clinical setting and identifies the routine management of this entity, which is in line with the standards proposed by recent clinical practice guidelines. A notable finding was that age and the number of comorbidities in NVUGIB patients were increasing. These factors could explain the persistent mortality rate, despite the evident advances in the management of this entity.

[Programme of screening for colorrectal cancer in the Valencia community, Spain: results of the first round (2005-2008)]. / Programa de cribado de cáncer colorrectal de la comunidad valenciana: Resultados de la primera ronda: 2005-2008.

BACKGROUND: Several studies evaluating colorectal cancer (CRC) screening with fecal occult blood testing (FOBT) have reported a significant reduction in mortality from this tumor. The study aims to describe the results of the first round of the CRC screening program in medium-risk population of Valencia and assessing their feasibility and acceptability. METHODS: Colorectal cancer screening pilot study using biennial FOBT. All residents (106,000 Inhabitants) between 50 and 69 years old (a subgroup of 70-74 years), from 3 selected health departments (04, 07 and 13) were invited by mail to participate. The individuals with FOBT positive were referred to hospital for colonoscopy. The following rates were calculated as indicators of program quality: the participation rate, positive FOBT rate, acceptance rate of colonoscopy, and detection rate of low and high-risk adenomas and invasive cancers, and positive predictive value of FOBT. RESULTS: The participation was 35,231 individuals (35.70%). The number of FOBT positive was 579 (1.64% of total analyzed test), 548 people agreed colonoscopy (acceptance rate: 94.69%). 61 CRC were detected, 61 and 153 High-Risk and Low-Risk Adenomas (rates of 1.77, 1.77 and 4.46% per 1,000 participants). The positive predictive values for cancer, low-risk and high risk adenomas were 10.95%, 10.95%, and 27.46% respectively. CONCLUSION: The program indicators suggest that a population program of colorectal cancer is feasible in our community as the process indicators obtained are similar to those given in other programs in Spain and Europe.

INTRODUCCIÓN: La presencia de hepatolitiasis (HL) es frecuente en los países orientales. Es una entidad poco descrita en series no-quirúrgicas. El tratamiento estándar para esta entidad es la opción quirúrgica. Actualmente el tratamiento ha evolucionado, aumentando el uso de técnicas endoscópicas y disminuyendo el número de resecciones hepáticas quirúrgicas. SpyGlass™ es un colangiopancreatoscopio endoscópico directo de pequeño calibre desarrollado para explorar y realizar procedimientos en el conducto biliar y pancreático. La colangioscopia peroral de operador único (POC) es una técnica endoscópica útil para tratar los cálculos complejos de las vías biliares. OBJETIVOS: Evaluar la utilidad, la eficacia y la seguridad de la colangioscopia POC con el sistema SpyGlass™ en pacientes con HL. Objetivos primarios: éxito técnico del procedimiento y el éxito clínico de pacientes con HL. DISEÑO: del estudio y pacientes Estudio de cohorte retrospectivo, unicéntrico de pacientes con HL desde abril de 2012 hasta agosto de 2018. SpyGlass™ fue elegido en pacientes sintomáticos remitidos desde la unidad de cirugía como procedimiento de primera línea. Para realizar litotricia electrohidráulica (EHL) se utilizó un generador Northgate Autolith® IEHL con una sonda biliar de 0,66mm. RESULTADOS: Se incluyó en el estudio un total de 13 procedimientos en 7 pacientes con HL. La edad media fue de 46 años (rango: 35-65) y 3/7 de los pacientes eran mujeres. Se logró éxito técnico en 5/7 casos (71,4%) y éxito clínico en 4/7 casos (57%). DISCUSIÓN: SpyGlass™ es seguro y efectivo en el tratamiento de HL. Con estos resultados, confirmamos la necesidad del manejo de pacientes con HL en un grupo multidisciplinar. Cuando el enfoque endoscópico es opción, este procedimiento debe realizarse para endoscopistas avanzados expertos

Inserción de una prótesis metálica autoexpandible como tratamiento de una neoplasia estenosante en una mujer embarazada / Insertion of self-expanding metal stent for treatment of malignant obstruction in a pregnant woman

El cáncer colorrectal (CCR) es el segundo tumor tanto en incidencia como en mortalidad en mujeres, sobre todo en mayores de 60 años. El diagnóstico en mujeres en edad gestacional es infrecuente por lo que su incidencia durante el embarazo es baja. Sin embargo, es posible que debido al aumento de la edad media de las gestantes se observe en los próximos años un incremento en el diagnóstico de esta patología. En la mayoría de ocasiones el diagnóstico se retrasa debido a que la sintomatología derivada del CCR puede atribuirse al propio embarazo. Hasta en un 30 % de los casos el CCR puede debutar como una obstrucción intestinal. En este caso el objetivo principal es solucionar el cuadro agudo de la forma más segura posible para madre y feto y realizar una aproximación diagnóstica adecuada para plantear el mejor manejo terapéutico, con las limitaciones y dificultades que supone la gestación. La prótesis metálica autoexpandible puede ser particularmente útil en la obstrucción de colon por CCR en la paciente embarazada ya que permite solucionar el cuadro agudo y proporciona el tiempo necesario para el estudio de extensión y preparación para la cirugía, reduciendo la morbimortalidad derivada de la misma. Presentamos el caso de una paciente que al inicio del segundo trimestre de gestación presentó un cuadro obstructivo secundario a una neoplasia de sigma que se resolvió satisfactoriamente con la colocación de una prótesis autoexpandible metálica

Colorectal cancer (CRC) is the second most frequent cancer both in incidence and mortality in women, especially in those over 60 years of age. Diagnosis in women at gestational age is rare, so its incidence during pregnancy is low. However, an increase in its diagnosis is expected during the next years because of the raise in the average age of pregnancy. In most cases, the diagnosis is delayed because symptoms related to CRC can be attributed to pregnancy itself. Up to 30 % of CRC cases may present as an intestinal obstruction. In this situation, the main objective is to solve the clinical emergency in the safest way for mother and fetus, together with performing an accurate diagnostic approach to offer the best possible therapeutic management knowing the limitations and difficulties related to pregnancy. The self-expanding metallic stent (SEMS) can be particularly useful in colon obstruction in a pregnant patient with CRC because it allows solving the acute condition providing time to perform a more accurate staging study and to prepare the patient for surgery, thus reducing both post-surgical morbidity and mortality. We report on the case of a patient who early in the second trimester of pregnancy presented with an acute colonic obstruction due to CRC which was successfully managed with the placement of a self-expanding metal stent (AU)

Situación actual del manejo de la hemorragia digestiva alta no varicosa en España / Current management of nonvariceal upper gastrointestinal bleeding in Spain

Introducción La mortalidad en la hemorragia digestiva alta no varicosa (HDA-NV) no ha variado. Se necesita conocer más información para mejorar las estrategias de tratamiento. Los objetivos de este estudio fueron: a) describir el perfil de presentación de los episodios de HDA-NV; b) el manejo clínico según práctica clínica habitual, y c) establecer cuáles son los resultados clínicos asociados a los tratamientos endoscópicos y médicos en España. Métodos ENERGIB fue un estudio retrospectivo de cohortes que recogió información del manejo y forma de presentación de HDA-NV en Europa. Presentamos los datos relativos a España. Los pacientes se trataron según la práctica clínica habitual. Para las variables cuantitativas se calculó la media y la desviación estándar y para las categóricas se calcularon frecuencias absolutas y relativas. Resultados Los pacientes (n = 403) fueron hombres (71%), con edad media 65 años, asociaron comorbilidad (62,5%). Los equipos encargados de su manejo fueron gastroenterólogos (57,1%) o médicos internistas (25,1%). Los inhibidores de la bomba de protones se usaron de forma empírica preendoscopia en un 80% de los casos. El 6,4% presentó persistencia y el 6,7% resangrado después de la endoscopia. La tasa de mortalidad en los 30 días posteriores fue del 3,5%.ConclusionesEste estudio permite conocer el perfil de presentación de los episodios de HDA-NV en España y el manejo en práctica clínica habitual. Este se ajusta a los estándares propuestos por las recientes guías de práctica clínica. Entre otros datos destaca que los pacientes con hemorragia son cada vez de edad más avanzada y presentan un mayor número de enfermedades asociadas, lo que podría explicar que la mortalidad se haya mantenido estable a pesar de los evidentes avances en el manejo de esta entidad (AU)
