A surgical stent (10) having elongate opposite end portions (12, 14) of different cross-sectional dimensions terminating in rounded terminal elements (16, 18) with rounded exterior surfaces is disclosed together with a surgical procedure for anastomosis of anatomical tubular organ structures. The stent contains a central canal (24) providing passage through the entire length of the stent and a plurality of annular ribs (20, 22) surrounding the exterior surfaces of the elongate portions (12, 14). The different cross-sectional dimensions of the two elongate portions (12, 14) allows selection of a stent to conform with the interior diameters of the lumena of the two sections of the tubular organ structure to be joined. The rounded exterior surfaces of the terminal elements (16, 18) and annular ribs (20, 22) assures a minimization of surgical trauma to the organ structure while the ribs minimize post-operative leakage at the site of the reanastomized tubular organ structure end sections.
