Diabetes and Colo Rectal Cancer
Colorectal cancer is related with diabetes mellitus and both of these common conditions are managed together by a surgeon. Type II (non- insulin dependent) diabetes seems to increase colorectal cancer incidence. Colorectal cancer and diabetes are both common diseases in the Western World. Countries that have taken up a western lifestyle have also seen an increase in the incidence of both colorectal cancer and diabetes. Both case control and cohort studies have shown that type II diabetes increases the lifetime risk of colorectal cancer by up to three times the risk to the general population and that diabetes is independently associated with greater mortality in colorectal cancers. Diarrhea is one of the most common symptoms of colonic cancer. Diarrhea especially at night is a result of autonomic neuropathy and diabetic neuropathy is one of the most common symptomatic complications of diabetes. Patients with diabetes who have autonomic neuropathy are more likely to develop constipation. Diabetic patients are also more likely to develop feacal incontinence. Impotence and both urinary and faecal incontinence following rectal surgery is certainly technique dependent in addition to factors including diabetes, smoking, alcohol and other medications. Anastomotic leak is the largest risk of mortality following colorectal surgery and most surgeons agree that diabetes is a risk factor in rectal surgery.
