Prospective Randomized Clinical Trial on Delay Phenomenon Utility in Preventing Oesophagogastric Anastomotic Dehiscence After Ivor-Lewis Esophagectomy. Pilot Study.
Prospective Randomized Clinical Trial on Delay Phenomenon Utility in Preventing Oesophagogastric Anastomotic Dehiscence After Ivor-Lewis Esophagectomy. Pilot Study.
This is a randomized clinical trial to clarify if the delay phenomenon could reduce the incidence of oesophagogastric dehiscence after an esophagectomy for esophageal cancer comparing an experimental group vs control group. The delay phenomenon will be performed by an arteriographic approach.
Subtotal esophagectomy with tubular gastroplasty to upper mediastinum and esophagogastric anastomosis (Ivor-Lewis procedure) is a very complex surgical technique. It is performed in patients with infracarinal esophageal carcinoma and is associated with a high morbidity rate in specialized centers (up to 60% in some groups). One of the most important postoperative complications is the oesophagogastric anastomotic leakage which leads to high morbidity (mediastinitis, respiratory failure, pleural effusion) and mortality rate (up to 60% depending on the reports).
The most important cause of anastomotic leakage is the stomach's extreme sensitivity to ischemic injury. There are several experimental studies that have demonstrated that the delay phenomenon before the esophageal resection surgery aims to improve blood perfusion after a period of time. Few studies, only case-reports, describe a decrease in the incidence of intrathoracic and cervical anastomotic leakage. May the delay phenomenon reduce the incidence of anastomotic intrathoracic leakage?. There aren't any prospective randomized controlled trials to answer this question.
For this reason the investigators propose to perform a prospective randomized controlled trial in patients who underwent a subtotal esophagectomy (Ivor-Lewis procedure), comparing two groups: one of them will be submitted to a delay phenomenon by arteriographic procedure before esophageal resection surgery, and the other one will be operated on directly, to demonstrate if the delay phenomenon can reduce the incidence of anastomotic esophagogastric leakage.
We decided to conduct this trial as a pilot study due to the fact that the number of patients needed to achieve statistical significance was to high and would have taken almost 10 years. We established a recruitment period of 3 years, in wich we intend to include 60 patients.
