Background
Anastomotic leakage (AL) is a serious complication after esophagectomy. The retrosternal (RS) route has been selected majorly to reduce reflux and related pneumonia and considering mediastinal recurrences. AL has been developed more in RS than posterior mediastinal (PM) route reconstruction. Therefore, we suspected the sterno-tracheal distance (STD) might be related to AL and started the selection according to the STD from 2009.
Methods
A total of 221 patients who underwent a subtotal esophagectomy with gastric tube reconstruction during January 2004–April 2017 were investigated. The patients were classified into the ‘after STD selection’ (A; n = 144) group and the ‘before STD selection’ (B, n = 77) group. The incidences of and the risk factors for AL between the two groups were compared.
Results
The incidence of AL was high in the B group (18.2%), and 78.6% of the patients who developed AL were treated with RS route reconstruction. The median STDs of the patients with AL and no AL were 10.3 mm and 14.5 mm, respectively (p = 0.001). These results demonstrated that the STD was a risk factor for AL in the RS route. Based on these results, 13 mm was set as the cutoff value. After STD selection, the median STD increased from 14.0 to 17.3 mm (p = 0.001), and the incidence of AL decreased significantly from 26.2 to 11.1% in the RS route (p = 0.037).
Conclusion
The STD was the independent risk factor for AL in the RS route. RS route reconstruction should be avoided for the patients with STD < 13 mm.
