Background And Aims:
Circumferential endoscopic submucosal dissection (C-ESD) is increasingly used for circumferential superficial esophageal squamous cell carcinoma (C-ESCC), although outcome data remain sparse. This study aimed to evaluate the short- and long-term outcomes of C-ESD in patients with C-ESCC.
Methods:
Clinical outcomes of patients with C-ESCC undergoing C-ESD at 2 Chinese centers were analyzed. Short-term outcomes included en bloc resection rate, curative resection rate, operation time, and adverse events. Long-term outcomes comprised overall survival (OS), disease-specific survival (DSS), cumulative recurrence rate (CRR), and the efficacy of stricture prevention and management.
Results:
A final assessment was conducted in 100 patients (100 lesions). The median lesion length was 5.2 cm (IQR, 4.5-6.0). Technical success rates were as follows: en bloc resection, 92.0% (95% CI, 85.0-96.4); R0 resection, 84.0% (95% CI, 75.6-90.5); and curative resection, 81.0% (95% CI, 72.3-88.3). The median procedure duration was 97.5 minutes (IQR, 70.5-138.3). Adverse events included delayed bleeding (3.0%), perforation (1.0%), and strictures (88.0%). With a median follow-up of 47.4 months (IQR, 34.3-65.2), 3- and 5-year OS and DSS were identical at 95.6% (95% CI, 91.4-99.9). Cumulative recurrence increased from 16.2% (3 years) to 19.8% (5 years). Prophylactic measures reduced stricture incidence (80% vs 100%; P = .007) and median number of endoscopic dilation sessions, 3 (IQR, 1-6) versus 4 (IQR, 3-9.8); P = .028. Stricture resolution was achieved in 95.5% of cases.
Conclusions:
C-ESD is an effective treatment for C-ESCCs. Although it achieves reliable oncological control with a favorable prognosis, its value is tempered by high stricture rates and a nonnegligible recurrence risk (∼20%). To optimize patient outcomes, advancing stricture prevention and ensuring rigorous long-term management are crucial future directions.
