Purpose: Esophagojejunostomy leakage (EJL) continues to be a serious and potentially fatal complication following total gastrectomy for gastric cancer. This study aimed to evaluate the clinical outcomes of endoscopic Histoacryl (B. Braun) injection in comparison to alternative treatment strategies for EJL. Methods: Out of 885 patients who underwent total gastrectomy at a single institution between January 2003 and August 2023, 26 (2.9%) developed EJL. Patients were categorized into four groups according to the management received:conservative treatment (n = 5), endoscopic Histoacryl injection (n = 10), reoperation (n = 8), and combined therapy (n = 3).Outcomes assessed included postoperative hospital stay, duration to oral intake, treatment success rate, and mortality. Results: Of the 26 patients with EJL, 3 (11.5%) succumbed to sepsis: two in the reoperation group and 1 in the Histoacryl group. In the 23 successfully managed cases, the Histoacryl group achieved the shortest median postoperative hospital stay, the shortest time to resuming of oral intake, and a 90% success rate without any procedure-related complications.The reoperation group experienced increased morbidity and mortality. Stent migration was reported in one patient from the combined treatment group. Differences in recovery between the four groups reached statistical significance (P < 0.05). Conclusion Endoscopic Histoacryl injection represents a safe, effective, and minimally invasive modality for managing EJL, providing improved recovery times and reduced complication rates. It is beneficial both as a primary intervention and as part of combination therapy.

Purpose: Esophagojejunostomy leakage (EJL) remains one of the most critical complications following total gastrectomy for gastric cancer. This study aimed to evaluate the evolving therapeutic approaches and clinical outcomes of EJL using data from a large-scale multicenter retrospective cohort. Methods: Among 6,577 patients who underwent total gastrectomy or proximal gastrectomy with double tract reconstruction at nine institutions from 2003 to 2024, 196 (3.0%) developed EJL. Of these, 162 patients with comprehensive clinical data were included in the final analysis. The study examined treatment modalities, changes in management over time, patient characteristics, surgical variables, and clinical outcomes. Four groups were defined according to treatment approach: conservative, endoscopic, reoperation, and multimodal (combined) therapy. Results: Endoscopic therapy was first introduced in 2011 and has progressively supplanted reoperation, now comprising 32.5% of cases. The average time to EJL diagnosis was 8.4 days after surgery. Overall in-hospital mortality was 6.1% (10/162). When conservative management was excluded, endoscopic treatment demonstrated the highest rate of therapeutic success (94.3%, p = 0.004). Both the duration until diet resumption and length of hospital stay were notably reduced in the endoscopic and conservative groups compared with reoperation and multimodal therapy (p < 0.001). Moreover, although the highest post-leakage hospitalization costs were observed with multimodal treatment (p < 0.001), overall hospitalization expenses were significantly lower for patients managed conservatively or with endoscopic intervention (p < 0.001). Conclusion Over the past two decades, management of EJL has shifted toward endoscopic approaches. Endoscopic therapies yield superior clinical outcomes and should be considered a primary option for appropriate candidates.
