Esophageal anastomosis introduction of mechanical

A variety of stapler in esophageal surgery applications, not only shorten the operation time, reduce tissue injury and blood loss, but also difficult to complete by hand suture anastomosis is possible to improve the outcome. Mechanical anastomosis has been used for nearly 200 years of history. 1827, Marseille, France's Denans active metal developed a "hoop ring" successful treatment of intestinal damage. But the advent of stapling device in 1966_ 1968, the United States Rzuitch and Steichen Nakayama in the Japanese on the basis of further Soviet-made staplers were a lot of improvement and development, making it even better.
After a series of stapling appears, has over 30 years, the 20th century 90 large hospitals in China are widely used. After the advent of mechanical anastomosis device, changing the method of esophageal surgery has been using a hand-fit the situation, the esophageal surgery has undergone a qualitative leap. Simple as stapling a fast, tight stitching, smooth and tidy and the cutting edge of security and the characteristics of high accuracy, which has been widely in clinical application. Mechanical esophageal anastomosis describes two;
Mechanical esophageal anastomosis of (1) the principle of mechanical anastomosis of esophageal cancer. For the esophagus and stomach (intestinal) mechanical stapler anastomosis is mainly based on the principles of design of the stapler, stapling "U"-shaped anastomosis nailed the role of external forces, through the esophagus and stomach need to match (intestinal) , and then bent into "" shape, stitched together the esophagus and stomach. In the past, can not be absorbed entirely consistent with nails of metal materials, have tried copper, silver, steel, aluminum and the buttons and other materials, clinical practice over a long period after the confirmation button of the human body the best compatibility, rarely cause inflammatory reaction can be retained in the organization without the long-term adverse reactions. In recent years, consistent with absorbable screw has been applied in foreign countries, and achieved satisfactory results.
Mechanical esophageal anastomosis Introduction (2) the application of esophageal mechanical anastomosis. With the development of anastomosis, anastomotic devices have been applied to various segments of esophageal surgery, according to the need to complete parts of a gastric esophagus (intestinal) end to side, end to end, side to side turn the entire layer anastomosis. However, patients should not be used when the following conditions mechanical anastomosis: severe preoperative obstruction, esophageal mucosal edema, thickening of esophageal wall thickening, or stomach or more than O.3cm; esophagus too small or too thin muscular wall of the esophagus After the nail into the slot in the first person prone to tear the wall; mechanical anastomosis after the failure of the first match suitable work.
Mechanical esophageal anastomosis in two broad categories: law and esophageal stapling the stomach cavity of a stretch cerclage. Among them, stapling methods include: a full stomach and esophageal anastomosis end to side; esophagus – some end to side anastomosis of the stomach; part of the stomach in esophageal side to side anastomosis; oral stapler anastomosis; of a cervical esophagus colonic side to side anastomosis; a stomach palliative esophageal side to side anastomosis.
