Viscera retainer which facilitates wound closure, for example, in the abdominal region, includes a body portion containing a tear seam. The body portion is inserted into the wound prior to closure to act as a physical barrier between the peritoneum and the viscera. A free extension of the body, or an attachment to the body, remains accessible outside the wound while a membranous layer of the abdominal wall is closed. When that closure is almost complete, the body portion is withdrawn from the abdomen by extracting it as a continuous ribbon through an opening. As the ribbon is withdrawn, the body tears along the tear seam generating free ribbon and shrinking the size of the residual body, until the entire body is removed from the abdominal cavity. The closure is then completed. A surgical drain has a planar body portion formed from a wound or wrapped tubular form having perforations in the body portion.
