This study was conducted in a tertiary referral center. PATIENTS: All consecutive patients undergoing redo pelvic surgery after low anterior resection for rectal cancer between January 2005 and March 2018 were included. INTERVENTIONS: Redo surgery was divided into redo anastomosis and intersphincteric completion proctectomy. Transanal minimally invasive surgery procedures since November 2014 were compared with the conventional approach. MAIN OUTCOME MEASURES: Primary end points were procedural characteristics and 90-day major complications. RESULTS: In total, 104 patients underwent redo surgery; 47 received a r...

Authors: Lega IC, Lipscombe LL Abstract Obesity and diabetes have both been associated with an increased risk of cancer. In the face of increasing obesity and diabetes rates worldwide, this is a worrying trend for cancer rates. Factors such as hyperinsulinemia, chronic inflammation, anti-hyperglycemic medications and shared risk factors have all been identified as potential mechanisms underlying the relationship. The most common obesity- and diabetes-related cancers are endometrial, colorectal and post menopausal breast cancers. In this review, we summarize the existing evidence that describes the complex relations...
