ABSTRACT
AIM: To explore the clinical application value of modified overlap anastomosis for Siewert type II and III adenocarcinoma of esophagogastric junction, and to further evaluate its feasibility and safety.
METHODS: We retrospectively analyzed clinical data from 222 patients with Siewert type II and III adenocarcinoma of the esophagogastric junction admitted to our hospital between January 2017 to October 2023. All patients underwent laparoscopic total gastrectomy with D2 lymph node dissection. 64 patients underwent esophagojejunostomy with modified overlap anastomosis, and 158 patients were operated using the circular stapled anastomosis. Variables that are statistically different were compared between groups using propensity score matching (PSM). The differences in surgical-related indicators and clinical outcomes for the two groups were compared. Finally, we analyzed the risk factors associated with esophagojejunostomy (EJ)-related complications.
RESULTS: There was no statistically significant difference between the two groups of patients in terms of BMI, gender, age, and tumor-related information (P value > 0.05). However, there was then a difference in preoperative hemoglobin between the two groups. To eliminate heterogeneity, we combined patients with PSM. In terms of intraoperative conditions and postoperative recovery after PSM, compared with the circular stapled anastomosis group, the modified overlap group showed the shorter total operation time, shorter the length of the auxiliary incision, shorter time to the soft diet intake, milder postoperative pain. In terms of postoperative complications and overall survival after PSM, the modified overlap group can reduce the probability of abdominal infection and there was no difference in overall survival (OS) and postoperative late complications between the two groups. Multivariate analysis showed that the Siewert type [odds ratio (OR), 0.355; 95% confidence interval (CI) 0.189-0.639, P value = 0.005] was independent risk factors of EJ-related complications.
CONCLUSION: Although the modified overlap group had slightly lower total protein after surgery, it had advantages in operation time, the length of the auxiliary incision, the soft diet intake time, postoperative pain, abdominal infection. General surgeons should exercise heightened vigilance in preventing EJ-related complications for patients classified as Siewert type II. In summary, modified Overlap anastomosis is safe and reliable. It has clinical application value.
