Endoscopic submucosal tunnel dissection for early esophageal squamous cell carcinoma in patients with cirrhosis: A propensity score analysis.

Background: Although early esophageal squamous cell carcinoma (EESCC) with cirrhosis is a relatively rare clinical phenomenon, the management of EESCC in cirrhotic patients continues to be a challenge.

Aim: To evaluate the feasibility, safety, efficacy and long-term survival outcomes of endoscopic submucosal tunnel dissection (ESTD) for treating EESCC in patients with cirrhosis.

Methods: This was a single-center retrospective cohort study. We examined 590 EESCC patients who underwent ESTD between July 14, 2014, and May 26, 2021, from a large-scale tertiary hospital. After excluding 25 patients with unclear lesion areas or pathological results, the remaining 565 patients were matched at a ratio of 1:3 by using propensity score matching. A total of 25 EESCC patients with comorbid liver cirrhosis and 75 matched EESCC patients were ultimately included in the analysis. Parametric and nonparametric statistical methods were used to compare the differences between the two groups. The Kaplan-Meier method was used to create survival curves, and differences in survival curves were compared by the log-rank test.

Results: Among 25 patients with liver cirrhosis and 75 matched noncirrhotic patients, there were no significant differences in intraoperative bleeding = 0.234) 30-d post-ESTD bleeding ( 0.099 disease-specific survival ( = 0.075), or recurrence-free survival ( = 0.8196) The mean hospitalization time and costs were significantly longer ( = 0.007) and higher ( = 0.023) in the cirrhosis group than in the noncirrhosis group. The overall survival rate was significantly lower in the cirrhosis group ( = 0.001).

Conclusion: ESTD is technically feasible, safe, and effective for patients with EESCC and liver cirrhosis. EESCC patients with A disease seem to be good candidates for ESTD.
