A B S T R A C T A surgical collection bag for post operative use having two opposed walls, secured together by a perimeter weld. One of the walls has an inlet opening through which the contents of the intestine of a patient can flow into the interior of the bag. The same wall also has a vent which is impervious to solid material and liquid from the intestine of the patient but which is pervious to gases. Welds inside the bag together with the perimeter weld define a pathway through which gases can flow from the interior of the bag to the vent. This pathway includes one or more vents through which gases must pass before they reach the vent. These gateways are sufficiently narrow at least substantially to prevent the passage of solid materials and liquids. If desired, the welds can be discontinuous to provide a multiplicity of gateways.
