A new technical approach to cancers of the cervical esophagus.

Abstract

The aim of this study was to assess the possibility of a primary end-to-end pharyngoesophageal anastomosis after standard tumor resection of the cervical esophagus by acute flexion of the neck. A total of 34 consecutive patients with primary cervical esophageal cancer, none having received prior radio- or chemotherapy, were treated by two methods based on intraoperative findings. In 18 patients, reconstruction after esophageal resection was carried out by the standard gastric pull-through technique (control group). In 16 patients, acute flexion of the neck after tumor resection allowed for reconstruction by primary end-to-end pharyngoesophagostomy (experimental group). There was no operative mortality in either group. The mean operative time for the experimental group was about 50 minutes less compared to the control group. Self-limited postoperative anastomotic leakage in the neck was twice as common in the experimental group. Postoperative dysphagia was about three times as common in the experimental group [5 patients (31%)] compared to the control group [2 patients (11%)]. In selected cases, segmental resection of primary cervical esophageal cancers reconstructed by end-to-end pharyngoesophagostomy is technically feasible by bending the neck acutely forward during anastomosis and maintaining it in the flexed position during a postoperative period of about 7 days. The advantages are reduced scope and duration of the operation. The downside is doubling of the frequency of postoperative cervical leakage.
