"Long-term oncologic outcomes and risk factors for distant recurrence after pathologic complete response following neoadjuvant treatment for locally advanced rectal cancer. A nationwide, multicentre study".

Background: Pathologic complete response (pCR) after multimodal treatment for locally advanced rectal cancer (LARC) is used as surrogate marker of success as it is assumed to correlate with improved oncologic outcome. However, long-term oncologic data are scarce.

Methods: This retrospective, multicentre study updated the oncologic follow-up of prospectively collected data from the Spanish Rectal Cancer Project database.

Diverticulitis with abscess formation: Outcomes of non-operative management and nomogram for predicting emergency surgery: The Diplicab Study Collaborative Group.

Background: To assess short- and long-term outcomes from non-surgical management of diverticulitis with abscess formation and to develop a nomogram to predict emergency surgery.

Methods: This nationwide retrospective cohort study was performed in 29 Spanish referral centers, including patients with a first episode of a diverticular abscess (modified Hinchey Ib-II) from 2015 to 2019. Emergency surgery, complications, and recurrent episodes were analyzed.

Neuroendocrine tumor associate with inflammatory bowel disease: two cases report.

Introduction: Patients with inflammatory bowel disease (IBD) have a higher risk of developing gastrointestinal tumors, the adenocarcinoma is the most frequently associated, and neuroendocrine tumor (NET) the most rare.

Clinical Cases: We present two patients, one with Crohn's disease and the other with ulcerative colitis, who present nonspecific symptoms, and after resection of an intestinal lesion, a gastrointestinal NET (GINET) is diagnosed.

Discussion And Conclusion: The GINET have an insidious clinic and these can be confused with those of the IBD.

[Tumor neuroendocrino ano-rectal: desde un pólipo con buen pronóstico hasta un carcinoma letal].

IntroducciÓn: Aunque los tumores neuroendocrinos rectales son neoplasias poco frecuentes, su incidencia está aumentando en las tres últimas décadas. El objetivo de este trabajo es el estudio del comportamiento de dichos tumores basándonos en sus variables clínicas, diagnósticas, terapéuticas y anatomopatológicas en un hospital terciario.

MÉtodo: Estudio retrospectivo de los tumores neuroendocrinos rectales desde el año 2000 hasta el año 2017 en nuestro hospital.

Quantification of Immune Dysregulation by Next-generation Polymerase Chain Reaction to Improve Sepsis Diagnosis in Surgical Patients.

Objectives: To quantify immunological dysfunction in surgical patients with presence/absence of sepsis using a droplet digital polymerase chain reaction (ddPCR) transcriptomic analysis. The study also aims to evaluate this approach for improving identification of sepsis in these patients.

Background: Immune dysregulation is a central event in sepsis.

Perceptions on the surgical treatment of inflammatory bowel disease in Spain. Results of a national survey.

Introduction: The incidence of inflammatory bowel disease (IBD) is increasing in Spain but there is little information on the availability of multidisciplinary care. This study aims to assess surgeon's opinions on the current situation of surgery for IBD in Spain.

Methods: An electronic closed survey was sent to members of the Spanish Association of Surgeons (AEC) from January to March 2015.

How to reduce the laparoscopic colorectal learning curve.

Background: The laparoscopic approach for colorectal pathologies is becoming more widely used, and surgeons have had to learn how to perform this new technique. The purpose of this work is to study the indicators of the learning curve for laparoscopic colectomy in a community hospital and to find when the group begins to improve.

Methodology: From January 1 2005 to December 31 2012, 313 consecutive laparoscopic colorectal surgeries were performed (105 rectal and 208 colonic) by at least 60% of the same surgical team (6 members) in each operation.
