“…Duhamel-based pull-through with side-to-side ileocolonic anastomosis proposed by Martin [20] was for years the predominant treatment [5,10,13,18,21,29,30]. Preservation of the absortive function of the aganglionic colon was attempted with several types of colonic patches [1,2,4,9,10,13,16,22,23,29,30] although straight ileo-anal pull-through with either Duhamel, Soave or Swenson techniques can serve the same purpose [7,8,11,32]. The first of the surgical techniques used at our institution to treat this condition deserves particular comment.…”
