title: Single-layer anastomosis without hemostasis in the submucosa layer by electric coagulation or ligation: a novel technique of anastomosis for all gastrointestinal tracts.
abstract: OBJECTIVE
  Single-layer anastomosis has been used extensively for all gastrointestinal tract around the world. Up to now, most of surgeons take it for granted that submucous layers need careful hemostasis either by electric coagulation or ligation for prevention of anastomotic stoma bleeding. We experienced hemostasis in the submucosa layer by adequate strength of anastomosis rather than electric coagulation for gastrointestinal tracts. In the present study was evaluated the safety and benefit of this novel anastomotic technique.
  
  
  METHODS
  From 1994 to 2006, 527 gastrointestinal anastomosis were performed using the improved anastomotic technique, and 281 anastomosis (control group) were completed with commonly adopted technique.
  
  
  RESULTS
  The improved anastomotic technique could decreased the incidence of leaks (p = 0.024), and procedure time required for anastomosis in comparison to control group (p = 0.0002). The incidence of abscesses (p = 0.51) and bleeding (p = 1.00) of the improved anastomotic technique were no significant between the groups.
  
  
  CONCLUSIONS
  The novel technique, single-layer anastomosis without hemostasis in the submucosa layer by electric coagulation or ligation, is suitable for all gastrointestinal anastomosises and it should be popularized.
