A stool management and collection system for acutely and chronically ill patients that prevents stool channeling and the consequential breakdown of patient skin. It comprises a bandage unit, a contour pad, a backing member, an easily connectible and releasable fastener, and a stool holding bag with a tapered upper portion. In addition, a diaper is used to collect patient urine and support the stool holding bag in approximately the same area where an incontinence pad is worn, instead of on the patients backside as in the prior art. Furthermore, the opening in the bandage unit should leave a minimum distance of approximately three-sixteenths of an inch around the patients rectal opening for the application of barrier cream or other skin-protecting substance. Super absorbent polymer (SAP) resin may be employed as a part of the systems structure, and a liner may be added to the stool collection bag.
