History of negative colorectal endoscopy and risk of rectosigmoid neoplasms at screening flexible sigmoidoscopy.
Screening sigmoidoscopy can reduce incidence of colorectal cancer and mortality. The optimal re-screening interval has not yet been defined. This study is aimed at estimating the risk of distal advanced adenomas (diameter >/=10 mm, villous component >20%, high-grade dysplasia) and cancer at screening flexible sigmoidoscopy in subjects aged 55-64 years who reported pre-screening negative colorectal endoscopy. ⋯ Our results are consistent with the hypothesis that the interval between screening sigmoidoscopies could be safely expanded beyond 5 years for subjects without specific risk factors for colorectal cancer.

Complications and recurrence after excision of rectal internal mucosal prolapse for obstructed defaecation.
Rectal internal mucosal prolapse (RIMP) may cause obstructed defaecation and encouraging short-term results have been reported after its transanal excision. The objective of this retrospective study was to assess both clinical and functional outcome after this procedure alone for patients presenting with evacuatory difficulty. ⋯ Primary excision of RIMP does not seem an effective treatment for obstructed defecation with predictive factors for an adverse outcome in terms of recurrence (RIMP and constipation) including the presence of preoperative non-relaxing puborectalis syndrome and a demonstrated anxiety or depression psychological profile. The technique of prolapsectomy does not seem to affect outcome.
