Finney-type [46] (side-to-side antiperistaltic) and Michelassi [47] (side-to-side isoperistaltic) strictureplasties have been widely used for strictures longer than 10 cm, with very good results [48-50].
Although laparoscopic total gastrectomy has developed relatively slowly because of technical difficulties [6], intracorporeal side-to-side reconstruction based on an antiperistaltic approach ("functional end-to-end anastomosis" [7]) or an isoperistaltic approach ("overlap anastomosis" [8]) is now performed.
