[Choice and technical problems of digestive tract reconstruction in laparoscopic gastrointestinal surgery]

Gastrointestinal tract reconstruction is a key procedure in laparoscopic surgery for gastrointestinal diseases. The reconstruction procedure in laparoscopic surgery is not superior to conventional surgery. Reconstruction procedures such as Billroth I, Billroth II( and Roux-en-Y anastomosis are widely used in laparoscopic assisted distal gastrectomy, while esophagojejunostomy by Roux-en-Y reconstruction is a reasonable option for laparoscopic assisted total gastrectomy. The OrVil technique provides an easier alternative to complete the esophagojejunostomy. Esophagogastrostomy is mainly used in laparoscopic assisted proximal gastrectomy. Colorectal anastomosis with double stapling technique and coloanal anastomosis with hand-sewn technique are common reconstruction procedures in laparoscopic surgery for mid and low rectal diseases. In laparoscopic colectomy, a small incision is usually used to facilitate the reconstruction extracorporeally. It is believed that innovation of instrumentation in the near future could bring us safer reconstruction devices with better efficiency and quality for laparoscopic surgery.
