The "barb line" and the application of 3D laparoscopy have solved the problem to some extent. In 2016,Intraluminal Stapler this procedure was improved,Intraluminal Stapler and it was proposed that without breaking the jejunum, the esophageal jejunum Overlap anastomosis was first performed and then the proximal jejunum was cut off, that is,Intraluminal Stapler the Overlap anastomosis method (Later-Cut Overlap method) was delayed from the broken jejunum. The "barb wire" suspension traction method is used to partially solve the problem of stump retraction after the esophagus is severed.

The FEEA, Overlap method and various improved surgical methods for total gastrectomy under laparoscopic surgery are completed under the microscope using a linear stapler,Intraluminal Stapler which avoids the need for purse suture and insertion of the nail seat under the microscope when using a circular stapler Complicated steps,Intraluminal Stapler the rate of anastomotic stenosis is low. Existing problems include: high requirements for esophageal freeness,Intraluminal Stapler at least 5 cm of free esophageal length is required for anastomosis; after the esophagus is broken, the stump is retracted to the lower mediastinum,Intraluminal Stapler the space is narrow,Intraluminal Stapler the operation is limited, and it is easy to cause "false channels" Anastomosis,Intraluminal Stapler which also requires higher jejunum and mesenteric tension, so it is not recommended for tumor invasion to more than 2 cm in the lower esophagus;Intraluminal Stapler π anastomosis and Later-Cut Overlap method both take the order of first digestive tract reconstruction and then remove the tumor. Check the margin before the reconstruction of the digestive tract. If the margin is insufficient after the anastomosis is completed,Intraluminal Stapler it is often necessary to open the chest and cut the mesentery to complete the anastomosis again. Therefore,Intraluminal Stapler it is recommended to be used only in patients with type III AEG or upper gastric cancer.
