Background/aims
Esophageal endoscopic submucosal dissection (ESD) performed under general anesthesia can potentially provide more stable treatment in difficult cases than that under sedation. We evaluated the clinical characteristics and outcomes of ESD performed under general anesthesia compared with those under propofol sedation and discussed the cases in which general anesthesia is recommended.
Patients and methods
In total, 292 lesions in 265 consecutive patients undergoing esophageal ESD at Yamaguchi University Hospital from 2013 to 2023 were included in this retrospective study.
Results
ESD was performed under general anesthesia for 92 lesions in 81 patients and under propofol sedation for 200 lesions in 184 patients. Tumor long-axis diameter was larger (39.8 ± 14.4 mm vs. 32.4 ± 9.9 mm, p < 0.01) and dissection speed was faster (10.5 ± 5.9 mm2/min vs. 7.5 ± 4.2 mm2/min, p < 0.01) in the general anesthesia group versus the sedation group. In the sedation group, a treatment history of pharyngeal cancer was significantly associated with a slower dissection speed (p = 0.037). The sedation group showed higher frequencies of hypoxemia (0% vs 9.8%, p < 0.01), interruption due to body movement (0% vs 13%, p < 0.01), and acute adverse events (21.7% vs 33.5%, p = 0.05). A treatment history of pharyngeal cancer was shown to be the significant factor contributing to acute adverse events (p = 0.018).
Conclusion
Esophageal ESD under general anesthesia can be a treatment option in patients with difficulty in performing stable procedures with propofol sedation. Especially in patients with a treatment history of pharyngeal cancer in whom ESD is more difficult to be performed and who are at higher risk for acute adverse events, general anesthesia can be considered.
