Purpose: To evaluate the effects of sucralfate on tissue content of neutral and acids mucins in rats with diversion colitis.
Methods: Thirty-six rats were submitted to a proximal right colostomy and a distal mucous fistula. They were divided into two groups according to sacrifice to be performed two or four weeks after intervention. Each group was divided into three subgroups according daily application of enemas containing saline, sucralfate at 1.0 g/kg/day or 2.0 g/kg/day. Colitis was diagnosed by histological analysis and neutral and acid mucins by Periodic Acid Schiff and Alcian Blue techniques, respectively. The contents of mucins were quantified by computer-assisted image analysis. Student's t paired and ANOVA test were used to compare the contents of both types of mucins among groups, and to verify the variance with time, establishing level of signification of 5% for both (p<0.05).
Results: Enemas containing sucralfate improves the inflammation and increases the tissue contents of neutral and acid mucins. The content of neutral mucins does not change with the time or concentration of sucralfate used, while acid mucins increases with concentration and time of intervention.
Conclusions: Sucralfate enemas improve the inflammatory process and increase the tissue content of neutral and acid mucins in colon without fecal stream.

: To evaluate the non-inferiority of non-contrast CT compared to contrast-enhanced CT with both intravenous and rectal contrast application for the diagnosis of acute colonic diverticulitis. : Five readers retrospectively evaluated the non-contrast and contrast-enhanced series of CTs of 205 consecutive patients with clinical suspicion of acute diverticulitis. Two randomized reading sessions, both containing all 205 cases as either contrast-enhanced or non-contrast (1:1) series, were performed with ≥8 weeks washout between them.

Chronic constipation refers to a reduction in the frequency of bowel movements and difficulty in defecation lasting for more than 6 months, with a comprehensive incidence rate of 15% in the population. Chronic constipation is a significant health concern that greatly affects the quality of life of patients and results in substantial healthcare resource consumption. Current common treatment strategies include lifestyle modifications, pharmacological therapy, biofeedback therapy, enemas, and surgical procedures, but the effectiveness of these approaches remains limited.
