Double roticulator stapling technique for low-lying rectal tumors.
A method is described for achieving proper distal margins in low-lying rectal lesions after initial resection indicates that these may be inadequate. The roticulator is kept on the distal rectal stump until the specimen has been examined. If additional margins are required, a second roticulator is placed distal to the first so that an intervening amount of tissue can be safely resected for adequate margins.
