Effect of tobacco use on Zenker's diverticulotomy outcomes.
American Journal of Otolaryngology 2024 March 20
OBJECTIVE: To compare clinical outcomes in patients with and without history of tobacco use who underwent Zenker's diverticulotomy (ZD).
STUDY DESIGN: Single institution retrospective review.
SETTING: Tertiary care academic hospital.
METHODS: A retrospective review of patients who underwent ZD via an open stapler, rigid endoscopic CO2 laser, stapler or harmonic scalpel, and flexible endoscopic technique from January 2006 to December 2020 was performed. Data were abstracted for patient demographics, diverticular features, and rates of adverse events and symptomatic recurrence.
RESULTS: Out of 424 patients, 146 (34.4 %) had a history of tobacco use: 126 (29.7 %) were former smokers, and 20 (4.7 %) were active smokers. In univariable cross-sectional analyses, the likelihood of postoperative bleeding, perforation, emergency department visits, unplanned readmission, or recurrence did not demonstrate an association with tobacco use history even after adjustment for age, sex, and surgical approach. Similarly, in Cox Proportional Hazards regression, tobacco use was not associated with an increased risk of recurrence, even after correcting for age, sex, and type of surgery. The median time to recurrence observed in our cohort was 11.5 years amongst non-smokers, 8.7 years amongst former smokers, and 1.2 years amongst active smokers (p = 0.94).
CONCLUSIONS: There were no significant differences in post-operative adverse events or frequency of recurrence of ZD between active, former, and non-smokers. Although underpowered and not statistically significant, median time to recurrence appears to be shorter in smokers when compared with former and non-smokers following surgery.
