Use of Darvadstrocel (Allogenic Stem Cell Therapy) for Crohn's Fistulas in Real Clinical Practice: The National Project to Implement Mesenchymal Stem Cell for the Treatment of Perianal Crohn's Fistula (the PRIME Study).

Background: Perianal fistulas may affect 15% to 50% of patients with Crohn's disease. Treatment is complex, requiring a multidisciplinary approach. Darvadstrocel (allogenic mesenchymal cells obtained from lipoaspirates) was approved in 2018 by the European and Spanish Agencies of Medicines and Medical Products as a treatment for fistulas in Crohn's disease.

Impact on defecatory, urinary and sexual function after high-tie sigmoidectomy: a post-hoc analysis of a multicenter randomized controlled trial comparing extended versus standard complete mesocolon excision.

Objective: To assess the effect of high inferior mesenteric artery tie on defecatory, urinary, and sexual function after surgery for sigmoid colon cancer. Performing a sigmoidectomy poses a notable risk of causing injury to the preaortic sympathetic nerves during the high ligation of the inferior mesenteric artery, as well as to the superior hypogastric plexus during dissection at the level of the sacral promontory. Postoperative defecatory and genitourinary dysfunction after sigmoid colon resection are often underestimated and underreported.

An analysis of randomized controlled trials on anal fistula conducted between 2000 and 2020 based on the Fragility Index and Reverse Fragility Index.

Aim: The aim of this work was to evaluate the robustness of randomized controlled trials (RCTs) on anal fistula management using the news tools of Fragility Index (FI), Reverse Fragility Index (RFI) and their corresponding fragility quotients.

Method: A systematic search was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines which utilized MEDLINE, EMBASE, Cochrane Library and Web of Science databases. Inclusion criteria included RCTs related to the management of anal fistula published from 2000 to 2022 with dichotomous outcomes measures and 1:1 allocation.

Exactitud diagnóstica en el cáncer de esófago localizado. Estudio observacional retrospectivo.

Objective: To assess the accuracy of the diagnostic tests for a correct clinical tumor staging in localized esophageal cancer (EC).

Method: Retrospective observational study of patients who underwent esophagectomy for cancer in a referral hospital between January 2003 and September 2019. Those patients who received neoadjuvant treatment were excluded in order to avoid bias from downstaging effects.
