Advantageous Short-Term Outcomes of Esophagojejunostomy Using a Linear Stapler Following Open Total Gastrectomy Compared with a Circular Stapler

Abstract

Esophagojejunostomy is one of the most important surgical procedures in total gastrectomy. In the past, esophagojejunostomy was exclusively performed using a circular stapler in open total gastrectomy (OTG). With the increasing frequency of its use in laparoscopic gastrectomy, esophagojejunostomy using a linear stapler has been performed in OTG. However, it is still unclear whether the use of a linear stapler in esophagojejunostomy following OTG has any advantages compared with the conventional use of a circular stapler. A total of 298 patients who underwent OTG for gastric cancer between 2014 and 2019 were enrolled in this study. Patients were categorized into circular and linear groups (group C and group L) according to the stapler type used for the esophagojejunostomy. After propensity score matching, 136 patients (68 each in groups C and L) were selected to compare the surgical outcomes including incidence of esophagojejunostomy-related complications and postoperative nutritional status. The median operation time was significantly longer in group L than in group C (261.5 min versus 325.5 min; P\u2009<\u20090.001). The incidence of esophagojejunostomy-related complications did not differ between the two groups (5.9% versus 2.9%; P\u2009=\u20090.68); however, no anastomotic stricture and bleeding occurred in group L. Bodyweight loss was significantly lower in group L than in group C at 6 months (15.9% versus 12.6%; P\u2009=\u20090.007) after surgery. Esophagojejunostomy using a linear stapler following OTG is equally safe and possibly advantageous in anastomotic stricture, bleeding and nutritional status compared with the use of a circular stapler.
