Endoscopic management of pancreatic collections. Endoscopic Ultrasound Group from the Spanish Society of Digestive Endoscopy (GSEED-USE) Clinical Guidelines.

Acute pancreatitis is associated with significant morbidity and mortality. It can develop complications such as fluid collections and necrosis. Infection of necrosis occurs in about 20-40% of patients with severe acute pancreatitis, and is associated with organ failure and worse prognosis. In the past years, the treatment of pancreatic collections has shifted from open surgery to minimally invasive techniques, such as endoscopic ultrasound guided drainage. These guidelines from a selection of experts among the Endoscopic Ultrasound Group from the Spanish Society of Gastrointestinal Endoscopy (GSEED-USE) have the purpose to provide advice on the management of pancreatic collections based on a thorough review of the available scientific evidence. It also reflects the experience and clinical practice of the authors, who are advanced endoscopists or clinical pancreatologists with extensive experience in managing patients with acute pancreatitis.

Expression of HMGCS2 in intestinal epithelial cells is downregulated in inflammatory bowel disease associated with endoplasmic reticulum stress.

Introduction: The Unfolded Protein Response, a mechanism triggered by the cell in response to Endoplasmic reticulum stress, is linked to inflammatory responses. Our aim was to identify novel Unfolded Protein Response-mechanisms that might be involved in triggering or perpetuating the inflammatory response carried out by the Intestinal Epithelial Cells in the context of Inflammatory Bowel Disease. Methods: We analyzed the transcriptional profile of human Intestinal Epithelial Cell lines treated with an Endoplasmic Reticulum stress inducer (thapsigargin) and/or proinflammatory stimuli. Several genes were further analyzed in colonic biopsies from Ulcerative Colitis patients and healthy controls. Lastly, we generated Caco-2 cells lacking HMGCS2 by CRISPR Cas-9 and analyzed the functional implications of its absence in Intestinal Epithelial Cells. Results: Exposure to a TLR ligand after thapsigargin treatment resulted in a powerful synergistic modulation of gene expression, which led us to identify new genes and pathways that could be involved in inflammatory responses linked to the Unfolded Protein Response. Key differentially expressed genes in the array also exhibited transcriptional alterations in colonic biopsies from active Ulcerative Colitis patients, including NKG2D ligands and the enzyme HMGCS2. Moreover, functional studies showed altered metabolic responses and epithelial barrier integrity in HMGCS2 deficient cell lines. Conclusion: We have identified new genes and pathways that are regulated by the Unfolded Protein Response in the context of Inflammatory Bowel Disease including HMGCS2, a gene involved in the metabolism of Short Chain Fatty Acids that may have an important role in intestinal inflammation linked to Endoplasmic Reticulum stress and the resolution of the epithelial damage.

The role of lumen-apposing metal stents (LAMS) in iatrogenic esophageal perforations secondary to endoscopic dilation of benign short esophageal strictures.

81 year-old male had an asymptomatic iatrogenic perforation after balloon dilation of esophageal strictures. After the migration of the full covered self expandable metal stent (FCSEMS), a lumen-apposing metal stent (LAMS) was placed and no esophageal leak was seen after. LAMS could be an appropiate first-line approach to benign short esophageal strictures complicated with iatrogenic small perforation but further prospective studies are needed.

Tratamiento percutáneo del carcinoma hepatocelular en pacientes con edad avanzada en la práctica clínica / Percutaneous ablation of hepatocellular carcinoma in older patients in clinical practice

INTRODUCCIÓN: Existe un alto porcentaje de pacientes con carcinoma hepatocelular (CHC) en estadio precoz con edad avanzada, que son potenciales candidatos a tratamiento percutáneo. MATERIAL Y MÉTODO: Evaluamos prospectivamente los datos de pacientes con CHC mayores de 70 años. Describimos sus características y el tratamiento pautado, así como la respuesta, las complicaciones y la supervivencia de los tratados con radiofrecuencia (RF) y/o inyección percutánea de alcohol (IPA). RESULTADOS: De los 194 pacientes con CHC, 84 eran mayores de 70 años (43,3%). La edad media era 76,8 ± 4,5 años. El 75% eran varones. El 91,7% eran cirróticos. El 61,9% se descubrió por cribado. Se diagnosticaron en estadio precoz (0-A) de Barcelona Clinic Liver Cancer el 60,7%, en B, el 19%, en C, el 12%, y en D, el 8,3%. El 38,2% recibió tratamiento potencialmente curativo (4,8% resección, 22,6% IPA, 4,8% RF, 6% IPA + RF), el 20,2%, quimioembolización, el 3,6%, sorafenib, el 25% no fue candidato a tratamiento, y el 13% rechazó el tratamiento recomendado. La mediana de seguimiento desde que recibieron el tratamiento percutáneo fue de 23 (IIC 14,2-40,6) meses. La media del número de sesiones de IPA fue de 3,5 ± 2,2 y de RF 1,8 ± 1,6. Hubo un 4% de complicaciones por sesión. Permanecieron en remisión el 35,7%. La mediana de supervivencia fue de 45,7 meses (IC 95% 20,8-70,6). CONCLUSIONES: El 43,3% de nuestros pacientes con CHC tenían una edad avanzada. Más de la mitad se diagnosticaron en estadio precoz. En un tercio se realizó tratamiento percutáneo, con un 35,7% de remisión y complicaciones poco frecuentes. Por lo tanto, este tipo de pacientes deben evaluarse para tratamiento percutáneo

INTRODUCTION: A high percentage of older patients with early-stage hepatocellular carcinoma (HCC) are potential candidates for percutaneous ablation.Material and methods We prospectively assessed data from patients older than 70 years with HCC. We determined their demographic and clinical characteristics, the treatment provided and the response, complications and survival among those treated with radiofrequency ablation (RFA) and/or percutaneous ethanol injection (PEI). RESULTS: Of 194 patients with HCC, 84 were older than 70 years (43.3%). The mean age was 76.8 ± 4.5 years. Seventy-five percent were male and 91.7% had cirrhosis. Cancer was initially identified by a surveillance program in 61.9%. According to the Barcelona Clinic Liver Cancer staging system, 60.7% were classified as having early stage cancer (0-A), 19% as stage B, 12% as stage C, and 8.3% as stage D. Potentially curative initial treatment was provided in 38.2% (surgical resection in 4.8%, PEI in 22.6%, RFA in 4.8%, PEI + RFA in 6%), transarterial chemoembolization in 20.2%, and sorafenib in 3.6%. Twenty-five percent of patients were not treatment candidates and 13% refused the recommended treatment. The median follow-up after percutaneous ablation was 23 months (IQR 14.2-40.6). The mean number of sessions was 3.5 ± 2.2 for PEI and 1.8 ± 1.6 for RFA. The complications rate per session was 4%. Remission was achieved in 35.7%. The overall median survival was 45.7 months (95% CI 20.8-70.6). CONCLUSIONS: Almost half of the patients with HCC in our sample were elderly and more than half were diagnosed at an early stage. Percutaneous ablation was performed in one-third of the sample, achieving remission in 37.5%. There were few complications. Therefore, these patients should be assessed for percutaneous ablation
