Impact on outcome of the route of conduit transposition after transhiatal oesophagectomy: A randomized controlled trial.
OBJECTIVE
To assess the influence of the route of conduit transposition after transhiatal oesophagectomy on the postoperative morbidity and mortality and late outcome at 6 months.


METHODS
Patients with oesophageal carcinoma, undergoing transhiatal oesophagectomy (gastric conduit), were randomized to either anterior or posterior route of conduit transposition. Patients with advanced tumour, distant metastasis, extensive invasion of the stomach, previous gastric surgery, any anterior mediastinal abnormality detected on preoperative imaging, ASA grade III/IV and poor preoperative pulmonary function were excluded. Intraoperative complications, postoperative morbidity and mortality and late outcomes were compared.


RESULTS
Of the 49 patients (34 men), 24 patients were randomized to the anterior mediastinal route and 25 to the posterior. The mean duration of the operative procedure (anterior: 235min; posterior: 225min) and the mean blood loss (anterior: 531ml; posterior: 538ml) were not statistically different. The most common complications were pulmonary and cardiac and comparable in both groups. Four patients died postoperatively. At 6-month follow-up the incidence of dysphagia, anastomotic stricture, anastomotic recurrence, aspiration and reflux symptoms and weight gain were similar.


CONCLUSIONS
The route of conduit transposition did not affect the outcome. However, an individualized approach depending upon the operative findings, radicality of the procedure, and perceived need for postoperative adjuvant therapy may be useful.
