In the literature, many articles refer to the DUHAMEL technique or some of its modifications in the treatment of Hirschsprung's disease, however, no complete review of all of them has been published to date. The authors present an analysis of the principal modifications of this technique based on the results of an international retrospective survey that evaluated a series of 2,430 patients as well as data from the literature. The important role of the internal anal sphincter in the physiology of continence is emphasized; understanding its function is an imperative prerequisite for a successful Duhamel procedure. The original technique, which used two crushing Kocher clamps as proposed by Duhamel in 1956, as well as a majority of the modifications with various spur-crushing instruments are no longer in use. At present, surgeons generally use staplers for the colorectal anastomosis.
