Background: Only a few data regarding colonic diverticulosis are available in Italy. We examined the frequency of colonic diverticulosis and its associations with risk factors in a homogeneous Northern Sardinian population undergoing colonoscopy for any reason in the last decades. Methods: This was a retrospective single-center study. Medical records of patients undergoing colonoscopy for any indication between 1995 and 2013 were reviewed. Demographic information including age, gender, geographic area (urban, rural), marital status, smoking habit, occupation, body mass index, and comorbidities were collected. Presence, number, and extension of diverticula were assessed by colonoscopy. The diagnosis of diverticulosis was defined by the presence of more than five diverticula. Results: A total of 4458 records were collected (39.8 % males). Analysis by birth cohorts showed a significant progressive age-related increase in the prevalence of diverticulosis. The average prevalence was 18.9 % without significant variation across the 19-year observation period. In 101 (12.1 %) subjects diverticula were single or few. Seventy-one percent of diverticula were located predominantly in the left side, 2 % in the right side, and 14.3 % were spread throughout the colon. There was a significant association with obesity but not with smoking habits, marital status, or urban versus rural environment. A strong association was observed between the presence of diverticulosis and cardiovascular and other gastrointestinal and lung disease ( p < 0.0001). These associations were also confirmed by the logistic regression analysis. Conclusions: In this endoscopic study, colonic diverticulosis in Northern Sardinia showed prevalence similar to other series in Western countries, and it was predominantly left sided and age related.

The article discusses a study that examined 17 female patients with obstructed defecation syndrome (ODS) with an average age of 59.35 years who underwent stapled transanal rectal resection (STARR) between 2005 and 2008. Twelve percent of the patients experienced postoperative bleeding that did not require reintervention. The results indicate that the benefit of STARR lessens over time.

Background: Although glucocorticosteroids (GS) and mesalazine are effective and widely employed to treat moderate-to-severe ulcerative colitis (UC), information regarding the factors responsible for response to such therapy is still scarce. One of these factors is thought to be an increased number of mucosal eosinophils. The aim of our study was to determine whether the presence of hypereosinophilia in colonic mucosa of UC patients might influence the short-term response to l treatment with GS and mesasalazine., Methods: Clinical, endoscopic, and pathologic data from patients with a recent diagnosis of moderate UC, who had not undergone treatment, were obtained, and the short-term outcome after 1 month of conventional first-line treatment (mesalazine plus GS) was evaluated., Results: There were 53 patients with a median age of 37 years (95% CI 30-47).Overall, at the end of treatment period 16 (30%) patients responded, whereas a response was not observed in the other 37 (70%) patients. Interestingly, all patients of this latter group had colonic mucosal hypereosinophilia. No significant differences were found between the two groups concerning sex and age at diagnosis, but hypereosinophilia was inversely correlated with the duration of the disease (p = 0.054), and significantly correlated to the localization of UC (p = 0.0023). In addition, The Mayo score was significantly higher in patients with hypereosinophilia (median 8; 95% CI 8-9;) when compared to patients without hypereosinophilia (median 7; 95% CI 7-7, p < 0.0001) including the Mayo endoscopic subscore (median 3; 95% CI 2-3 vs median 2; 95% CI 2-2, respectively; p = 0.007)., Conclusions: The presence of colonic mucosal hypereosinophilia may be useful to predict the short-term outcome to conventional first-line therapy in treatment-naïve UC patients. It remains to be seen whether this might be important in modifying the first-line therapy in this subgroup of patients.
