Does laparoscopic surgery decrease the risk of atrial fibrillation after foregut surgery?
Abstract
Background: Atrial fibrillation, which occurs in 12% of all major foregut surgeries, can prolong hospital stay and increase morbidity. Minimally invasive techniques in foregut surgery have been suggested to cause less tissue trauma. We examined the factors associated with new-onset atrial fibrillation after foregut surgery at our institution.
Methods: We retrospectively examined the records of 154 adult patients who underwent major foregut surgery which included esophagectomy, partial or total gastrectomy, redo Heller myotomy, redo or transthoracic fundoplications. Univariate and multivariate logistic regression analysis with standard modeling techniques were performed to determine risk factors for new-onset atrial fibrillation.
Results: Of the 154 patients, 14 patients developed new-onset atrial fibrillation with a higher mean age of 67.1 years (+/-8.8 years) versus 56.4 years (+/-14.1 years) (p = 0.006). Laparoscopic (p = 0.004) and nonthoracic surgeries (p = 0.01) were associated with lower risk of atrial fibrillation. Patients with atrial fibrillation had received more fluid (6.5 +/- 2.8 liters versus 5.3 +/- 2.0 liters) and had longer operations (370 +/- 103 min versus 362 +/- 142 min), none of which were statistically significant. The average intensive care length of stay of patients was longer: 7.5 +/- 6.8 days versus 4.0 +/- 7.1 days (p = 0.004). Multivariate analysis revealed an association of atrial fibrillation with age (OR 1.08, 95% CI 1.02-1.14, p = 0.01), and…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 154 participants or records.
