title: [Does the third staple line of a new endostapler offer an advantage?].
abstract: BACKGROUND
  In laparoscopic colon surgery, endostaplers generate 2 parallel rows of staples. The aim of this paper is to analyse whether the introduction of a new endostapler generating a third row of staples influences the rate of anastomotic leakage and bleedings.
  
  
  METHODS
  362 patients of the Department of Surgery, University Clinic of Schleswig-Holstein, Campus Lübeck, were included in this study. All patients underwent colon resection with performance of double-stapling anastomosis. In Group I (n = 148; 7 / 2004 to 12 / 2005), the Endopath TSB 45 endostapler (2 rows of staples) was used, whereas in Group II (n = 214; 7 / 2006 to 12 / 2007), the Echelon60 EC60 stapler (3 rows of staples) was used. All further operational steps were identical for both groups. Target parameters were the postoperative anastomotic leakage and anastomotic bleeding rates.
  
  
  RESULTS
  Between July 2004 and December 2005, the number of anastomotic leaks (Stapler Endopath, TSB 45) was n = 4 (2.7 %), for the second period (Stapler Echelon60 EC60), it was n = 9 (3.7 %) (not significant). Using the Endopath TSB 45 stapler, the number of anastomotic bleedings was n = 12 (8.1 %), and for the Echelon60 EC60 stapler, it was n = 8 (3.7 %) (p = 0.074; not significant). Within the 18-month period between July 2006 and December 2007, the number of endoscopic colon operations (n = 214) rose by 44.6 % compared to the 18-month period between July 2004 and December 2005 (n = 148).
  
  
  CONCLUSIONS
  The application of the advanced Echelon endostapler has no impact on the number of anastomotic leaks, and reduces the number of anastomotic bleedings slightly but not significantly. The increased number of endoscopic procedures in the second period results both from the growing number of indications for the application of endoscopic techniques and the positive findings of recent studies carried out by our own and other working groups.
