SILS colorectal resection is feasible and safe when performed by an experienced laparoscopic surgeon and theatre team. It may have advantages over conventional laparoscopic surgery in terms of reduced pain, lower cost, faster recovery and cosmesis.

The relationship between behaviour problems and intelligence was examined in a sample of 106 three-year-old boys and girls selected for the presence of either conduct problems or hyperactivity. Parents' reports of hyperactivity, but not conduct problems, were negatively related to IQ scores for both boys and girls. There was a significant sex difference in the association between conduct problems and IQ. For girls IQ was positively correlated with conduct problems. The implications of the results for existing models of the relationship between behavioural deviance and cognitive functioning in childhood is discussed.

The results demonstrate that MR proctography under-reports pelvic floor abnormalities especially where there has been poor rectal evacuation.

Background Closure of an abdominal stoma, a common elective operation, is associated with frequent complications; one of the commonest and impactful is incisional hernia formation. We aimed to investigate whether biological mesh (collagen tissue matrix) can safely reduce the incidence of incisional hernias at the stoma closure site. Methods In this randomised controlled trial (ROCSS) done in 37 hospitals across three European countries (35 UK, one Denmark, one Netherlands), patients aged 18 years or older undergoing elective ileostomy or colostomy closure were randomly assigned using a computer-based algorithm in a 1:1 ratio to either biological mesh reinforcement or closure with sutures alone (control). Training in the novel technique was standardised across hospitals. Patients and outcome assessors were masked to treatment allocation. The primary outcome measure was occurrence of clinically detectable hernia 2 years after randomisation (intention to treat). A sample size of 790 patients was required to identify a 40% reduction (25% to 15%), with 90% power (15% drop-out rate). This study is registered with ClinicalTrials.gov, NCT02238964.
