GENERAL
This is a case report of a patient with esophagobronchial fistula (EBF) after
esophagectomy. The authors reported their experience of the three-step surgery
that salvaged the patient from chronic respiratory failure. Although the case was
clinically interesting, the issues addressed in the present study were highly
surgical and would be unfamiliar to readers of BMC Gastroenterology. In
addition, the literature review was not sufficient. This reviewer thinks that the
present manuscript does not meet the high standards for publication in BMC
Gastroenterology and recommends submission to a surgery-specific journal after
thorough revision. 
SPECIFIC
1. This reviewer recommends a systemic search of literature on bypass surgery
for EBF and the presentation of the summary.
2. The authors overlook the paper of Bamba et al. (Esophagus 2008). They have
reported a three-step bypass surgery for EBF with a similar concept.
