title: All mechanical low rectal anastomosis in children.
abstract: OBJECTIVE
  The aim of this study is to demonstrate the feasibility and usefulness of mechanical suturing in children for low rectal anastomosis.
  
  
  METHODS
  The study group includes 31 children operated on from January 1993 to July 1996 by the same senior surgeon, performing the modified Duhamel procedure for Hirschsprung's disease in 17 children, intestinal neuronal dysplasia in seven, and the Knight-Griffen procedure in seven pediatric patients with chronic ulcerative colitis.
  
  
  RESULTS
  In all the cases the technique of "viscero-synthesis" was performed using the mechanical stapler. A circular stapler has been used for the end-to-end and the end-to-side anastomosis between the anal canal or the back wall of the rectum with the pulled viscus, while a linear endoscopic stapler (GIA) has been used for the consolidation of the rectocolic wall in the modified Duhamel technique.
  
  
  CONCLUSIONS
  The results obtained demonstrate that the mechanical staplers in children are safe and effective in low rectal anastomosis, sparing operative time and reducing the risk of anastomotic dehiscence; however, the size of circular instruments limits its use in neonates and small infants.
