Abstract
Objective Assess impact of reconstructive procedures on patients undergoing laryngopharyngectomy and to determine whether 30-day postoperative morbidity and mortality varied between patients who underwent flap reconstruction and those who did not.
Study Design Retrospective analysis of the prospectively collected American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database.
Setting Tertiary medical center.
Subjects and Methods We reviewed the 2005-2011 ACS-NSQIP database to identify patients undergoing laryngectomy and/or pharyngectomy. Bivariate analysis was done to compare preoperative variables and postoperative outcomes between the flap reconstruction group and non-reconstruction group. Chi-square tests were used for categorical variables and t-tests for continuous variables. Logistic regression analysis was performed to calculate odds ratio to account for potential confounders. To create a valid logistic analysis model, F-test was used to determine whether certain variables should be included in the model.
Results Six hundred seventy-six patients were included in our study; 213 patients received concurrent flap reconstruction whereas 463 did not. After risk adjustment, analyses revealed no statistically significant difference in wound complication, minor morbidity, and mortality between the 2 groups. The flap reconstruction cohort showed significantly longer operative times (8.09 3.36 hours vs 5.63 +/- 3.47 hours; P = .001) and higher major morbidity rate (OR = 5.906, 95% CI, 3.131-11.139, P = .001).
Conclusions This is the first comprehensive analysis of flap reconstruction for laryngopharyngeal defects using the ACS-NSQIP registry. Additional measures involved in flap reconstruction are associated with an increase in major morbidity but not mortality. An understanding of these variables may optimize the decision-making process for patients undergoing laryngectomy and/or pharyngectomy.
