Background: To detect anastomotic leakage after esophagectomy in esophageal carcinoma patients, many surgeons perform a radiological contrast examination routinely. The aim of this retrospective study is to determine the clinical relevance of a routine contrast examination after esophagectomy and to evaluate criteria for contrast examination on demand.
Methods: Data were obtained from 211 patients with cancer of the esophagus or gastro-esophageal junction who underwent an esophagectomy during the period 1991-2004. Retrospectively, we analyzed patients regarding anastomosis-related characteristics and clinical signs including sepsis, fever > or = 39.0 degrees C, leukocytosis > or = 20 x 10(9)/ml and pleural effusion.
Results: Anastomotic leakage had appeared in 35 of the 211 patients. The clinical signs sepsis (odds ratio (OR) 6.72: 95% confidence interval (CI) (2.57-17.56); P < 0.0001), leukocytosis (OR 2.62 (1.10-6.22); P < 0.030), and fever (OR 2.34 (1.01-5.42); P < 0.047) were significantly related to anastomotic leakage. Pleural effusion was not significantly related to anastomotic leakage (OR 2.83 (0.98-8.13); P = 0.054).
Conclusion: Our study suggests that the clinical value for a routinely performed contrast examination is debatable. We recommend performing a contrast examination based on clinical suspicion and clinical signs of anastomotic leakage including sepsis, fever > or = 39.0 degrees C and leukocytosis > or = 20 x 10(9)/ml.
