    BackgroundAnastomotic leaks are a major complication of oesophagogastric surgery. We compare contrast swallow fluoroscopy, computed tomography (CT) with oral contrast and endoscopy in identifying anastomotic leaks following oesophagogastric surgery.MethodsA prospective trial of 38 patients undergoing oesophagogastric resection was undertaken with informed consent and institutional review board (ethics committee) approval. Patients underwent all three investigations (over 24 hours) 1 week postoperatively.ResultsEight (21%) had clinically apparent leaks. Three pseudo-leaks were suggested on contrast swallow but were confirmed normal on CT and endoscopy. Contrast swallow and CT missed one anastomotic leak each. Endoscopy identified anastomotic defects in three patients, in whom CT and contrast swallow were either normal or conflicting.ConclusionsRoutine tests of anastomotic integrity are unnecessary. When clinically suspected, contrast swallow or CT with oral contrast will identify most leaks. Endoscopy is useful in cases where there are incongruous results.
