A retrospective study of provisional outcomes of intracorporeal esophagojejunostomy versus extracorporeal anastomosis during laparoscopic total gastrectomy for gastric cancer. a single -center.

Abstract

Gastric cancer (GC) treatment is increasingly undergoing laparoscopic total gastrectomy (LTG) procedures. However, we conducted this research to evaluate postoperative outcomes, particularly surgical complications associated with intracorporeal and extracorporeal esophagojejunostomies using linear or circular stapling techniques following LTG for GC treatment. We aimed to compare short-term postoperative outcomes, such as surgical complications and anastomotic outcomes, between the two groups. Method From January 2020 to August 2022, we conducted a retrospective analysis of data from 160 consecutive patients diagnosed with GC who received either IEJ (n = 35) or EEJ (n = 125) during LTG. We utilized the Mann-Whitney U test to ascertain the statistical significance between the two groups. For comparing categorical variables, including numbers and percentages, we employed either the Pearson chi-square test, continuity correction, or Fisher's exact test as appropriate.ResultsThe operative time was similar (IEJ: 184.57 ± 36.489 vs. EEJ: 189.22 ± 43.584; P = 0.565), however, the number of positive lymph nodes was performed more in the IEJ group (IEJ: 4.71 ± 6.114 vs. EEJ: 6.39 ± 9.067 (P = 0.305). The blood loss in the IEJ group was lower than that of the EEJ (IEJ: 73.1429.182 vs. EEJ: 100.6461.693 mL, P = 0.012). There were three anastomosis leakages in the EEJ and one in the IEJ group (EEJ, 3.2% vs. IEJ, 2.8%; P > 0.999). Anastomosis bleeding only occurred in the EEJ (EEJ 1%; P = 0.003). Although the EEJ linear stapling technique had two deaths (EEJ, 1.6%).ConclusionAlthough EEJ is frequently utilized in the linear stapling technique, research indicates that the use of IEJ minimizes the incidence of complications in LTG.
