Ulcerative colitis (UC) often necessitates total colectomy in cases of medically refractory disease or complications, with over one-third of patients undergoing surgery despite advances in medical therapy. Standardization in colectomy techniques is crucial to improving surgical outcomes, enhancing reproducibility, and addressing variability in practices. This study revisits laparoscopic total colectomy, emphasizing a "critical view of safety" approach to streamline the procedure, reduce anatomical disorientation, and overcome steep learning curves for trainees.

Article Synopsis
  • - The study investigates the effectiveness of Narrow Band Imaging (NBI) for identifying lesions in ulcerative colitis (UC) using three different classification systems: NICE, Kudo, and the modified Kudo-IBD.
  • - Results showed disparities in diagnostic performance, with Kudo-IBD achieving the highest sensitivity (86%) and specificity (79%), indicating its superiority for UC lesion characterization compared to NICE and Kudo classifications.
  • - The findings suggest that while NBI's overall diagnostic accuracy for distinguishing between neoplastic and non-neoplastic lesions in UC is generally low, the modified Kudo classification significantly improves this accuracy.

Article Synopsis
  • This study compares two surgical methods, Hartmann's procedure (HP) and resection with primary anastomosis (RPA), for treating acute left-sided colonic emergencies among 1215 patients from 204 centers globally.
  • Results showed that while HP was the more common treatment (57.3%), RPA was favored for younger patients with fewer health issues and those needing surgery sooner.
  • The study concluded that although HP is still widely used, RPA might be the better option, emphasizing the importance of patient characteristics and surgeon experience in determining treatment choice.

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is a complex, immune-mediated, disorder which leads to several gastrointestinal and systemic manifestations determining a poor quality of life, disability, and other negative health outcomes. Our knowledge of this condition has greatly improved over the last few decades, and a comprehensive management should take into account both biological (i.e.

Emergency subtotal colectomy is the standard treatment for acute severe ulcerative colitis (ASUC) unresponsive to medical treatment. No guidelines are available about surgical technique. The aim of the current survey was to identify the attitudes of Inflammatory Bowel Disease (IBD) surgeons concerning colectomy in patients with ASUC by means of a nationwide survey, with specific focus on intraoperative technical details.

Purpose: Assessment of inflammatory bowel disease (IBD) currently relies on aspecific clinical signs of bowel inflammation. Specific imaging of the diseased bowel regions is still lacking. Here, we investigate mucosal addressin cell adhesion molecule 1 (MAdCAM-1) as a reliable and specific endothelial target for engineered nanoparticles delivering imaging agents to obtain an exact mapping of diseased bowel foci.

Acute severe colitis is the major indication for surgery in inflammatory bowel diseases (IBD), and in particular, in ulcerative colitis (UC). A laparoscopic approach for abdominal colectomy is recommended, due to better perioperative and long-term outcomes. However, costs, time-spending, and outcomes are still a topic of improvement.

Objectives: Several studies have investigated, with conflicting results, the risk factors for reoperation in Crohn's disease (CD) patients. CARD15 gene variants have been identified as a major genetic risk factor for CD patients and associated with ileal disease, stenosis, and risk of surgery. However, data regarding the association between these variants and the need for reoperation are very few and conflicting.
