Improved anastomotic technique for esophagojejunal anastomosis using circular stapler

In total gastrectomy, Roux-en-Y reconstruction with esophagojejunal anastomosis has been widely used in gastrointestinal reconstruction. In the case of anastomotic leakage of RY reconstruction, esophagojejunal anastomosis should be paid attention, and esophageal fragility is considered the reason for the leakage. Here, we introduce an atraumatic and innovative technique for esophagojejunostomy.

We prospectively performed routine novel esophagojejunal anastomosis using circular stapler device and reviewed the records of 14 consecutive patients with gastric cancer who underwent open total gastrectomy at Kitasato University Hospital from April 2019 to March 2020. By placing about 10 stay sutures around the entire esophageal stump, the esophageal stump can be opened to the maximum diameter. The forceps grasping the tissue was not necessary for these procedures, consequently preventing either tears the esophageal stump tissue or narrowing the esophageal lumen.

These 14 cases were far advanced cases of gastric cancer, 6 cases of splenectomy and 3 cases of distal pancreatectomy. No technical problems such as esophageal tear were observed in all cases. Postoperative complications were observed in 6 patients (42.9%), and their contents varied. However, they all improved conservatively. Regarding anastomotic complications, anastomotic leakage of Clavien-Dindo-II was observed in one case, but it improved conservatively.

Our new atraumatic anastomosis technique could abolish problems such as tear of esophagus wall due to introduce a larger-sized anvil, trauma of esophageal wall by grasping with forceps such as Alice or Babcock. Consequently, the atraumatic and innovative technique might make the esophagojejunostomy safe. This method might prevent anastomotic leakage and other complications effectively.
