Endoscopic removal of lumen-apposing metal stents - risk factors for stent embedment, complex removals, and adverse events: analysis from a multicenter prospective case series.

BACKGROUND: Removing lumen-apposing metal stents (LAMSs) may be difficult and even harmful, but these features have seldom been analyzed. We aimed to generate a comprehensive assessment of the feasibility and safety of LAMS retrieval procedures. METHODS: A prospective multicenter case series including all technically successfully deployed LAMSs between January 2019 and January 2020 that underwent endoscopic stent removal. All retrieval-related data were prospectively recorded using standardized telephone questionnaires as part of centralized follow-up that ended after stent removal had been performed. Multivariable logistic regression models assessed the potential risk factors for complex removal. RESULTS: For the 407 LAMSs included, removal was attempted in 158 (38.8 %) after an indwell time of 46.5 days (interquartile range [IQR] 31-70). The median (IQR) removal time was 2 (1-4) minutes. Removal was labelled as complex in 13 procedures (8.2 %), although advanced endoscopic maneuvers were required in only two (1.3 %). Complex removal risk factors were stent embedment (relative risk [RR] 5.84, 95 %CI 2.14-15.89; P = 0.001), over-the-wire deployment (RR 4.66, 95 %CI 1.60-13.56; P = 0.01), and longer indwell times (RR 1.14, 95 %CI 1.03-1.27; P = 0.01). Partial and complete embedment were observed in 14 (8.9 %) and five cases (3.2 %), respectively. The embedment rate during the first 6 weeks was 3.1 % (2/65), reaching 15.9 % (10/63) during the following 6 weeks (P = 0.02). The adverse event rate was 5.1 %, including seven gastrointestinal bleeds (5 mild, 2 moderate). CONCLUSIONS: LAMS removal is a safe procedure, mostly requiring basic endoscopic techniques attainable in conventional endoscopy rooms. Referral to advanced endoscopy units should be considered for stents with known embedment or long indwell times, which may require more technically demanding procedures.

Prospective multicenter assessment of the impact of EUS-guided gastroenterostomy on patient quality of life in unresectable malignant gastric outlet obstruction.

BACKGROUND AND AIMS: EUS-guided gastroenterostomy (EUS-GE) is increasingly used for malignant gastric outlet obstruction (GOO) in inoperable patients. However, the impact of EUS-GE on patient quality of life (QoL) has not been evaluated prospectively. METHODS: Consecutive patients with unresectable malignant GOO who underwent EUS-GE between August 2019 and May 2021 at 4 Spanish centers were prospectively assessed using the European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 at baseline and 1 month after the procedure. Centralized follow-up by telephone calls was undertaken. The Gastric Outlet Obstruction Scoring System (GOOSS) was used to assess oral intake, defining clinical success as a GOOSS ≥2. Differences between baseline and 30-day QoL scores were assessed using a linear mixed model. RESULTS: Sixty-four patients were enrolled, 33 (51.6%) men, with a median age of 77.3 years (interquartile range, 65.5-86.5). The most common diagnoses were pancreatic (35.9%) and gastric (31.3%) adenocarcinoma. Thirty-seven patients (57.9%) presented a 2/3 baseline Eastern Cooperative Oncology Group performance status score. Oral intake was restarted within 48 hours in 61 patients (95.3%), and the median postprocedure hospital stay was 3.5 days (interquartile range, 2-5). The 30-day clinical success rate was 83.3%. A clinically significant increase of 21.6 points (95% confidence interval, 11.5-31.7) in the global health status scale was documented, with significant improvements in nausea and vomiting, pain, constipation, and appetite loss. CONCLUSIONS: EUS-GE relieves GOO symptoms in patients with unresectable malignancy, allowing rapid oral intake and hospital discharge. It also provides a clinically relevant increase in QoL scores at 30 days from baseline. (Clinical trial registration number: NCT04660695.).

Acute calculous cholecystitis: a real-life management study in a tertiary teaching hospital

Aim: to describe the management of acute calculous cholecystitis in a tertiary teaching hospital and the outcomes obtained. Material and methods: a retrospective single tertiary center cohort study. Results: medical records of 487 patients were analyzed. The mean follow-up was 44.5 +/- 17.0 months. Treatment alternatives were cholecystectomy (64.3%), conservative treatment (23.0%), endoscopic retrograde cholangiopancreatography (17.4%), percutaneous cholecystostomy (10.7%) and endoscopic ultrasound-guided gallbladder drainage (0.8%). Most cholecystectomies were delayed (88.8%). Recurrences occurred in 38.2% of patients. Although cholecystectomy was the therapeutic approach with the lowest recurrence rate once performed, 44.6% of patients that underwent delayed surgery had pre-surgical recurrences. Conclusions: delayed cholecystectomy is still commonly performed, even though it is related with a high frequency of preoperative recurrences

Collagenous sprue: don´t forget connective tissue in chronic diarrhea evaluation.

Collagenous sprue is a rare disease of the small bowel characterized by mucosal atrophy and excessive subepithelial collagen deposition. The etiology remains unclear and the diagnosis is based upon patient´s clinical picture and anatomopathological findings. Clinically, collagenous sprue is characterized by persistent diarrhoea, severe malabsorption, multiple nutrient deficiencies and progressive weight loss. Differential diagnosis includes celiac disease, which is mandatory to rule out because of their frequent association. Glutenfree diet is the first therapeutic step, but it usually is not effective. However, recent studies show high success rates with immunomodulators, mainly corticosteroids. We report the case of a patient presenting with chronic diarrhea and severe malabsorption who was diagnosed with collagenous sprue, with no response to gluten free diet, but with excellent response to budesonida.

Esprúe colágeno: no olvidemos el tejido conectivo en la evaluación de la diarrea crónica / Collagenous sprue: don’t forget connective tissue in chronic diarrhea evaluation

El esprúe colágeno es una patología infrecuente del intestino delgado caracterizada por atrofia de la mucosa y depósito excesivo de colágeno a nivel subepitelial. Su etiología es desconocida y su diagnóstico se realiza en base a la presencia tanto de un cuadro clínico compatible como de hallazgos anatomopatógicos sugestivos. Los pacientes suelen presentar diarrea crónica, malabsorción, deficiencias nutricionales graves y una marcada pérdida ponderal. Dentro del diagnóstico diferencial es mandatorio descartar enfermedad celiaca por su frecuente asociación a la misma. La dieta sin gluten es el primer escalón terapéutico, pero generalmente no es efectiva. Sin embargo, estudios recientes señalan altas tasas de éxito mediante el uso de inmunomoduladores. Presentamos el caso de un paciente con diarrea crónica y malabsorción grave diagnosticado de esprúe colágeno, sin respuesta a la dieta sin gluten, en el que el tratamiento con budesonida ha conseguido una excelente respuesta(AU)

Rescate con sulfasalazina antes de inmunosupresores o agentes biológicos en la colitis ulcerosa mal controlada con mesalazina / Rescue therapy with sulfasalazine prior to immunosuppressive or biological agents in ulcerative colitis poorly controlled with mesalazine

Introducción Los salicilatos son el tratamiento de elección en la fase de mantenimiento de la colitis ulcerosa. El primer salicilato fue la sulfasalazina, prácticamente sustituida por la mesalazina por su supuesta mejor tolerancia. Estudios recientes indican que la mesalazina podría ser menos eficaz que la sulfasalazina. Nos planteamos si los pacientes mal controlados con mesalazina en fase de mantenimiento podrían responder a sulfasalazina antes de progresar a inmunosupresores o biológicos. Métodos De los pacientes con colitis ulcerosa de la consulta de Enfermedad Inflamatoria Intestinal del Hospital Ramón y Cajal, seleccionamos los tratados con mesalazina y en los que la sulfasalazina se había utilizado como tratamiento de mantenimiento de rescate. Determinamos qué porcentaje de pacientes insuficientemente controlados con mesalazina respondieron a sulfasalazina. Resultados De 415 pacientes con colitis ulcerosa, 49 habían tomado SSZ en algún momento. En 31, este tratamiento se indicó como alternativa a la ineficacia de la mesalazina. El tiempo medio de tratamiento con mesalazina antes del cambio había sido de 20,8 meses, siendo la dosis media utilizada de 3,35g/día. La dosis media de sulfasalazina empleada fue de 2,5g/día. En 21 de los 31 pacientes (67,7%) se consiguió mantener la remisión con la sulfasalazina. Conclusión A pesar de las limitaciones de nuestro estudio, en el 67,7% de los pacientes con colitis ulcerosa mal controlados con mesalazina, el cambio a sulfasalazina resultó eficaz. Dado que se trata de pacientes en los que el siguiente paso sería el empleo de inmunosupresores o biológicos, creemos que esta opción merece estudios controlados y que en todo caso la sulfasalazina no debe desterrarse en el manejo de pacientes con colitis ulcerosa(AU)

In ulcerative colitis, aminosalicylates are the mainstay of maintenance therapy. Sulfasalazine was the first aminosalicylic used in the maintenance therapy of this disease. Later, mesalazine was preferred due to its supposedly better tolerability. However, recent studies indicate certain benefits of the use of sulfasalazine because of its possible superior effectiveness. The aim of this study was to determine whether patients with ulcerative colitis poorly controlled by mesalazine as maintenance therapy respond to sulfasalazine, thus avoiding the use of immunosuppressive or biological therapies. Methods The Inflammatory Bowel Disease Clinic of the Ramón y Cajal Hospital maintains a database in which all drug exposures are registered. We selected patients poorly controlled with mesalazine who had received sulfasalazine as rescue maintenance therapy. We determined the percentage of patients poorly controlled with mesalazine who responded to sulfasalazine. Results Of 415 patients with ulcerative colitis, 49 had been treated with sulfasalazine at some time. Of these, sulfasalazine was selected as an alternative therapy due to poor disease control with mesalazine. The median duration of mesalazine therapy until the switch was 20.8 months, with a median dose of 3.35g/day. In 21 of the 31 patients (67.7%), sulfasalazine was able to control symptoms and maintain remission. Conclusion Despite the limitations of this study, we found that 67.7% of patients with ulcerative colitis poorly controlled with mesalazine responded to a switch to sulfasalazine. These patients would normally have progressed to immunosuppressive, biological or surgical treatments. This option merits further studies. Meanwhile sulfasalazine should not be forgotten in the management of ulcerative colitis (AU)

Linfoma T asociado a enteropatía: un reto diagnóstico / Enteropathy-associated T-cell lymphoma: a diagnostic challenge

El diagnóstico de la enfermedad celíaca resistente (ECR) se establece, tras la exclusión de otras entidades, ante la persistencia de datos clínicos de malabsorción y atrofia vellositaria durante 6-12meses a pesar de una estricta dieta sin gluten (DSG). La detección de alteraciones en la población linfocitaria intraepitelial es importante para su diagnóstico. Un subgrupo de pacientes con ECR pueden desarrollar complicaciones severas, como linfoma T asociado a enteropatía (LTAE). Presentamos el caso de un paciente con EC silente de larga evolución que finalmente derivó en LTAE y que evidencia el reto que supone para el clínico tanto el diagnóstico como el tratamiento de esta entidad (AU)

Diagnosis of refractory celiac disease (CD) is based on exclusion of other disorders, persistence of malabsorptive symptoms and villous atrophy, despite a strict gluten-free diet for at least 6-12months. Detection of alterations in the intraepithelial lymphocyte population is crucial for diagnosis. A subgroup of patients with refractory CD may develop severe complications such as enteropathy-associated T cell lymphoma (EATL). We present the case of a patient with longstanding silent CD who developed EALT, highlighting the challenge posed by the diagnosis and treatment of this entity (AU)
