Abstract

OBJECTIVE:

The aim of this study was to the determine impact of severe esophageal anastomotic leak (SEAL) upon long-term survival and locoregional cancer recurrence.

BACKGROUND:

The impact of SEAL upon long-term survival after esophageal resection remains inconclusive with a number of studies demonstrating conflicting results.

METHODS:

A multicenter database for the surgical treatment of esophageal cancer collected data from 30 university hospitals (2000-2010). SEAL was defined as a Clavien-Dindo III or IV leak. Patients with SEAL were compared with those without in terms of demographics, tumor characteristics, surgical technique, morbidity, survival, and recurrence.

RESULTS:

From a database of 2944 operated on for esophageal cancer between 2000 and 2010, 209 patients who died within 90 days of surgery and 296 patients with a R1/R2 resection were excluded, leaving 2439 included in the final analysis; 208 (8.5%) developed a SEAL and significant independent association was observed with low hospital procedural volume, cervical anastomosis, tumoral stage III/IV, and pulmonary and cardiovascular complications. SEAL was associated with a significant reduction in median overall (35.8 vs 54.8 months; P = 0.002) and disease-free (34 vs 47.9 months; P = 0.005) survivals. After adjustment of confounding factors, SEAL was associated with a 28% greater likelihood of death [hazard ratio = 1.28; 95% confidence interval (CI): 1.04-1.59; P = 0.022], as well as greater overall (OR = 1.35; 95% CI: 1.15-1.73; P = 0.011), locoregional (OR = 1.56; 95% CI: 1.05-2.24; P = 0.030), and mixed (OR = 1.81; 95% CI: 1.20-2.71; P = 0.014) recurrences.

CONCLUSIONS:

This large multicenter study provides strong evidence that SEAL adversely impacts cancer prognosis. The mechanism through which SEAL increases local recurrence is an important area for future research.
