After 6 d from perineal rectosigmoidectomy, the patient, was discharged free of complications. Four days later he was readmitted in emergency for strangulated perineal trans-anastomotic ileal hernia that occurred at home during efforts to defecate. The clinical feature required an emergency operation for repositioning the ileal loops into the abdomen, resection of the necrotic ileum, and end colostomy. The outcome of the second operation was free of complication and the patient was discharged on the 6(th) postoperative day. In conclusion, after Altemeier operation prolonged straining at defecation should be carefully avoided.

The dramatically high social and economic impact of CRC on human health makes the identification of a reliable screening tool of paramount importance. Current screening methods, such as the fecal occult blood test and colonoscopy do not adequately meet the ideal requisites of a screening test because, even if they are effective, they are limited first by too low specificity and sensitivity, or second by high invasiveness, costs and risk. Nowadays extended efforts are made by researchers to look for more reliable and effective screening tests based on a systems biology approach, using biological samples easily available, such as urine, breath, serum and feces. The effectiveness and reliability of several new attempts to screen these patients by non-invasive analysis of their biological samples using genomic (genetic and epigenetic alteration), transcriptomic (miRNA), proteomic (cancer-related antigens, new antibodies against tumor-associated antigens, mutated proteins) and metabolomic (volatile organic metabolites) methods are discussed in this review. Among the most interesting new screening tools, fecal fluorescent long-DNA, fecal miRNA and metabolomic evaluation in breath and/or serum seem to be most promising.
