Background: Primary repair of penetrating wounds of the colon is gaining increasing acceptance in surgical practice. This study compared two techniques for the repair of experimental colonic perforations in the presence of peritonitis.
Methods: Multiple colonic perforations were created in the colon of 24 pigs. Following a 6-h delay the perforations were closed either by local excision and suture or by skin staples applied to the seromuscular layers of the colon. The repairs were assessed biomechanically and histologically for up to 14 days after surgery.
Results: All animals had diffuse peritonitis at the time of colonic repair. Stapled repairs were completed significantly faster than sutured repairs (mean(s.d.) 4.8(1.6) versus 30.7(4.0) min, P < 0.001). Bio- mechanical evaluation of repairs revealed no significant differences between the two techniques. Histological examination of repairs closed by staples demonstrated more advanced healing compared with suture closure, on the basis of tissue apposition and inflammatory changes.
Conclusion: Experimental colonic injuries may be treated successfully by primary repair in the presence of peritonitis. The use of skin staples for repair does not appear to prejudice colonic wound healing.
Introduction: Ulcerative colitis (UC) is a chronic inflammatory condition of the intestinal tract in which mucosal healing is a crucial measure of therapeutic efficacy. Quercetin, a flavonoid prevalent in various foods and traditional Chinese medicines, exhibits notable pharmacological properties, including antioxidant and anti-inflammatory activities. Consequently, it warrants investigation to determine its potential therapeutic effects on UC.

Background: Acquisition of stem-like properties requires overcoming the epigenetic barrier of differentiation and re-expression of several genes involved in stemness and the cell cycle. DNA methylation is the classic epigenetic mechanism for de/differentiation. The writers and erasers of DNA methylation are not site-specific enzymes for altering specific gene methylation.
Objective: The aim of this study is to provide solid evidence to update the management of stage I colon cancer (CC) after surgery.
Background: Given the low risk of recurrence of stage I CC, some international guidelines do not recommend intensive follow-up after surgery. However, data on the actual incidence, risk factors, and site of recurrences are scarce.
Background: Oligo-metastatic disease (OMD) in colon cancer patients exhibits distinct clinical behavior compared to poly-metastatic disease (PMD), with a more responsive and indolent course. This study aims to identify clinical and biological factors uniquely associated with oligo-metastatic behavior.
Methods: Metastatic colon cancer patients from an academic center underwent genetic characterization.
Background: Whereas restoration of fecal consistency after treatment with clioquinol for chronic diarrhea and free fecal water syndrome has been attributed to its antiprotozoal properties, actions of clioquinol on the colonic bacterial microbiota have not been investigated.
Objectives: Characterize the dynamics of fecal microbial diversity before, during, and after PO administration of clioquinol to healthy horses.
Study Design: Experimental prospective cohort study using a single horse group.
