[A new technic for esophago-enteral anastomosis with a mechanical stapler without purse-string sutures]

Abstract

Staplers have improved the results of esophageal surgery, in our experience and in others experience, as esophago-enteric anastomoses have become safer and faster than when manual suturing is used. Probably one of the last problems in the stapler technique, especially in the thoracic area, is the performance of on adequate esophageal purse-string suture: an improper performance of this suture can cause a dangerous leak of the anastomosis. So, many surgeons, to reduce the risk of esophageal dehiscence connected with the esophageal purse-string, use either purse-string devices or alternative methods such as a second handsewn purse-string, U stitches of the esophagus, etc. We think that the risk of improper anastomoses after esophageal resection can be reduced if the need for the esophageal purse-string can be eliminated. This work shows our personal technique for performing esophagoenterostomy, especially in the thoracic area, using the new CEEA stapler (Autosuture) without esophageal purse-string sutures. According to the modified procedure the stapler anvil and the mini rod are introduced in the esophagectomy and a 2-0 thread is knotted around the CEEA mini rod. Then the esophageal mutilated part is closed by a linear stapler keeping a syringe needle, which contains the thread, through the linear suture. Then, using the thread as a pulling system, the surgeon makes the needle and the tip of the mini rod slide out of the esophageal suture. Now the surgeon can reassemble the CEEA and perform the anastomosis. There are many clinical reports that cite no leaks following circular stapled anastomoses across linear stapled closures.
