ObjectiveTo investigate the high risk factors for perioperative atrial fibrillation (AF) and its effect on the postoperative short term outcome in esophageal carcinoma patients. MethodsSixty three patients with AF after esophagectomy (AF group) and 126 patients without AF after esophagectomy in control group were analyzed by χ 2, and logistic regression, and compare with patient the postoperative mortality and duration hospitalization in two groups.ResultsThe rates of age above 65 (χ 2=7.02, P lt;0.01), male sex (χ 2=4.06, P lt;0.05), history of cardiac disease (χ 2=6 03, P lt;0.05), history of chronic obstructive pulmonary disease (COPD, χ 2=29.14, P lt;0 01), postoperative thoracic gastric dilatation ( P lt;0.01), and postoperative lower oxygen saturation ( P lt;0.01) in AF group were significantly higher than those in control group. No significant relevance was found between history of diabetes or hypertension, choice of operative approach, site of stoma and postoperative AF. 1 in 15 AF patients regain sinus rhythm after remove the pathological factors, and the others resumed after antiarrhythmic drug therapy. The postoperative hospitalization time was 10.65±0.87 d in patients developing AF group and 9.98±0.96 d in control group ( P gt;0.05). No difference was observed between two groups with regard to mortality ( P gt;0.05).ConclusionAF occurs more frequently after esophagectomy in aged and male sex. Other factors contributing to AF are history of cardiac disease, COPD and lower oxygen saturation. And in this study, early occurrence of AF after operation for esophageal carcinoma does not show any negative impact on mortality or on postoperative duration hospitalization.
