The impact of diabetes mellitus on outcomes of endoscopic sinus surgery: a nested case-control study.

ABSTRACT: Given the immune impairment associated with diabetes mellitus (DM), its impact on chronic rhinosinusitis (CRS) is a potentially relevant concern; however, it has not been well-studied. A single retrospective study reported worse postoperative quality of life outcomes in DM patients with CRS. Our study evaluated the effect of comorbid DM on outcomes of endoscopic sinus surgery (ESS) using a prospective study design.Using a multicentered, prospective cohort of patients (n = 437) undergoing ESS for recalcitrant CRS, a nested case-control comparison was performed between 20 adult DM patients (cases) and 20 non-DM patients (controls), matched 1:1 for age and Lund-Mackay computed tomography (CT) scores. Outcome measures included 22-item Sinonasal Outcome Test (SNOT-22), Rhinosinusitis Disability Index (RSDI), Patient Health Questionnaire (PHQ-2), and Brief Smell Identification Test (BSIT).Mean follow-up was similar between cases (mean ± standard deviation: 12.6 ± 6.0 months) and controls (12.9 ± 5.9 months; p = 0.862). All preoperative scores were statistically equivalent between DM and non-DM cohorts. Both cohorts showed significant post-ESS improvement in SNOT-22 (p = 0.001) and RSDI scores (p < 0.001), and no significant change in PHQ-2 or BSIT scores. The magnitude of score changes was statistically equivalent between the 2 cohorts for all outcome measures with no differences in postoperative score changes between insulin-dependent DM patients and those managed by oral hypoglycemics or dietary restriction (p ? 0.444).DM patients with CRS experience similar degrees of symptomatic benefit from ESS compared to controls. Insulin dependence does not appear to adversely affect surgical outcome but a larger cohort would better assess the effect of DM type and control on surgical outcomes in CRS.

Project description:OBJECTIVES:There is little consensus regarding the prognostic value of symptom duration in predicting clinical disease severity or quality-of-life (QOL) outcomes in patients with chronic rhinosinusitis (CRS). Our objectives were to: 1) determine if patients with longer symptom duration have worse preoperative disease severity and/or QOL, and 2) determine if delayed surgical intervention influences outcomes of endoscopic sinus surgery (ESS). METHODS:Patients diagnosed with CRS were prospectively enrolled into a multicenter cohort study and observed 14.7 (standard deviaton {SD}?±?4.8) months on average following primary ESS. Preoperative symptom duration was stratified into short-term (<?12 months), middle-term (12-60 months), and long-term (>?60 months). Disease severity was assessed using endoscopy and computed tomography. Disease-specific QOL was measured with the 22-item Sinonasal Outcome Test (SNOT-22) and Rhinosinusitis Disability Index. Adjusted bivariate and multivariate associations between symptom duration, disease severity, and QOL scores were evaluated. RESULTS:One hundred and thirteen patients met inclusion criteria with 35 patients lost to postoperative follow-up. No significant differences in preoperative disease severity or QOL scores were reported between symptom duration subgroups. Participants in the long-term symptom subgroup reported significantly greater mean postoperative improvement on SNOT-22 total scores (n?=?28; -36.3[±?22.2]) compared to both short-term (n?=?27; -23.4[SD?±?11.3]; P?=?0.039) and middle-term (n?=?23; -23.5[SD?±?20.1]; P?=?0.050) subgroups. Postoperative QOL improvements in the long-term symptom subgroup remained significantly greater (P???0.036) after multivariate adjustment. CONCLUSIONS:Symptom duration was not associated with mean preoperative disease severity or QOL. Patients with long-term symptom duration reported the greatest mean postoperative QOL improvement, suggesting that delayed surgical intervention may not reduce QOL improvements following ESS.
