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.

Method: Single-center retrospective cohort analysis of UC patients undergoing abdominal and anorectal surgery between January 2000 and December 2020. The care burden, clinical data and results were analyzed according to distribution by decades.

Characteristics and oncological results of epidermoid anal carcinoma: Comparison analysis between immunocompetent and immunosuppressed patients.

Objective: Most evidence, including recent randomized controlled trials, analysing anal squamous cell carcinoma (SCC) do not consider immunocompromise patient population. The aim of this study was to compare clinical and oncological outcomes among immunocompetent and immunocompromised patients with anal squamous cell carcinoma.

Method: Multicentric retrospective comparative study including 2 cohorts of consecutive patients, immunocompetent and immunocompromised, diagnosed with anal SCC.

Prognostic Value of the Circumferential Resection Margin After Curative Surgery for Rectal Cancer: A Multicenter Propensity Score-Matched Analysis.

Background: Recently, positive circumferential resection margin has been found to be an indicator of advanced disease with a high risk of distant recurrence rather than local recurrence.

Objective: The study aimed to analyze the prognostic impact of the circumferential resection margin on long-term oncological outcomes in patients with rectal cancer.

Design: This was a multicenter, propensity score-matched (2:1) analysis comparing the positive and negative circumferential resection margins.

Incidence and risk factors for de novo cholelithiasis after bariatric surgery.

Introduction: Obesity and rapid weight loss after bariatric surgery (BS) are risk factors for the development of cholelitiasis. The aim of this study is to know the incidence of the de novo symptomatic cholelitiasis (DNSC) after BS and to analyze the risk factors for its development.

Methods: Single-centre retrospective observational study of patients undergoing BS between January 2010 and December 2017.

Care burden and outcome of the surgical management of ulcerative colitis: A retrospective analysis of the last 20 years in a tertiary hospital in Spain.

Extended Versus Standard Complete Mesocolon Excision in Sigmoid Colon Cancer: A Multicenter Randomized Controlled Trial.

Objective: The aim of this study was to evaluate whether extended complete mesocolic excision (e-CME) for sigmoid colon cancer improves oncological outcomes without compromising morbidity or functional results.

Background: In surgery for cancer of the sigmoid colon and upper rectum, s-CME removes the lymphofatty tissue surrounding the inferior mesenteric artery (IMA), but not the lymphofatty tissue surrounding the portion of the inferior mesenteric vein that does not run parallel to the IMA. Evidence about the safety and efficacy of extending CME to include this tissue is lacking.

Incidence and risk factors for de novo cholelithiasis after bariatric surgery.

Introduction: Obesity and rapid weight loss after bariatric surgery (BS) are risk factors for the development of cholelitiasis. The aim of this study is to know the incidence of the de novo symptomatic cholelitiasis (DNSC) after BS and to analyze the risk factors for its development.

LIFT procedure for posterior fistula-in-ano. Are outcomes good enough? A systematic review and meta-analysisis of observational studies.

Introduction: Efficacy of the ligation of intersphincteric fistula tract (LIFT) procedure for posterior fistula-in-ano remains under debate. However, there is scarcity of quality evidence analysing this issue. Thus, the aim of this study is to evaluate outcomes of LIFT surgery in patients with posterior anal fistula.

Diagnóstico inesperado en paciente con sospecha de GIST: infiltración gástrica por mieloma múltiple.

El mieloma múltiple se caracteriza por la proliferación neoplásica medular de células plasmáticas productoras de inmunoglobulina monoclonal. Un porcentaje pequeño de pacientes presenta compromiso extramedular en forma de plasmocitoma, siendo la localización más habitual las vías respiratorias altas. La afectación gastrointestinal es rara y la clínica asociada dependerá de la localización, la extensión y el mecanismo de infiltración.

Early-rectal Cancer Treatment: A Decision-tree Making Based on Systematic Review and Meta-analysis.

Local excision (LE) has arisen as an alternative to total mesorectal excision for the treatment of early rectal cancer. Despite a decreased morbidity, there are still concerns about LE outcomes. This systematic-review and meta-analysis design is based on the "PICO" process, aiming to answer to three questions related to LE as primary treatment for early-rectal cancer, the optimal method for LE, and the potential role for completion treatment in high-risk histology tumors and outcomes of salvage surgery.
