![]() ![]() The average distance from the upper esophageal resection margin to the tumor in the 24 overlap anastomoses performed at our center was 2.4 ☐.6 cm, which is shorter than that of the OrVil anastomosis. However, the length of the small intestine and esophagus required for overlap side-to-side anastomosis is significantly longer than that required for end-to-end anastomosis with a circular stapler. The p-value was > 0.05, which may be related to the small sample size. The average anastomosis time was 24.40 ☖.1 min, slightly less than that of OrVil anastomosis. The common opening was closed by manual continuous suture with a fixed barbed suture. At our center, we have also performed side-to-side anastomosis between the posterior wall of the esophagus and the anterior wall of the small intestine after barbed suturing on both sides of the esophageal stump and pulling down the esophagus. Since then, there have been some minor improvements in this anastomosis method, mainly focusing on the selection of anastomotic stoma and the suturing of the common opening. This procedure has the advantages of antegrade peristaltic emptying of the anastomosis, a wide anastomotic caliber and low anastomotic tension. first reported the use of esophagojejunal overlap anastomosis for digestive tract reconstruction after laparoscopic total gastrectomy in 2010. Therefore, for Siewert type II AEG with a stage ≥ cT2 and esophageal invasion > 2 cm, we believe that the use of OrVil anastomosis can achieve safer and more satisfactory esophageal resection margins. Our study found that OrVil anastomosis can provide an upper resection margin distance of 3.2 ☐.84 cm. It has also been found that for Siewert type II AEG with esophageal invasion 3.8 cm (an in vivo distance of approximately 5 cm) was an independent risk factor for a poor prognosis. 112 lymph nodes are 3.4% and 2.0%, respectively. 110, with a metastasis rate of 9.0%, while the rates of metastasis to lymph nodes No. ![]() ![]() In recent years, the continuous progress in laparoscopic techniques and studies of lymph node metastasis in Siewert type II AEG have shown that mediastinal lymph node metastasis of Siewert type II AEG mainly affects the inferior mediastinum the most commonly affected lymph node is No. Due to the tumor’s special anatomical location, its biological behaviors are complex the extent of tumor invasion and lymph node metastasis present certain difficulties in selecting the treatment strategy, surgical method and resection range, and clinical surgeons have directed considerable attention to these issues. Siewert type II AEG is defined as an AEG in which the center of the tumor is located 1 cm above the dentate line to 2 cm below the dentate line. Because tumors at this site have special biological characteristics, radical surgery remains the primary treatment option. Adenocarcinoma of the esophagogastric junction (AEG) is an adenocarcinoma located at the junction of the esophagus and gastric cardia, and its incidence has increased in recent years. ![]()
