Outpatient parotidectomy with or without the use of a post-operative drain: A retrospective bi-institutional study

Patient-Reported Quality-of-Life Outcome Measure After Parotidectomy

Importance

There is a lack of reliable, patient-reported quality-of-life (QOL) instruments to address the multidimensional nature of patient-centered outcomes for patients undergoing parotidectomy. The Parotidectomy Quality of Life Index is a new 35-item validated patient-reported outcome instrument specific to recovery after parotidectomy.

Objective

To establish and validate a comprehensive English-language patient-reported QOL instrument specific to parotidectomy.

Design, Setting, and Participants

This survey study was conducted in 2 phases: first, in a single-institution cohort (October 12, 2021, to March 7, 2022), and second, as an anonymous web-based survey enrolled via printed promotional brochures and social media platforms (March 13 to July 31, 2023). Inclusion criteria were age at least 18 years and parotidectomy within the last year. For test-retest reliability, a subset of phase II participants volunteered to answer the survey a second time within 2 weeks. Data were analyzed from March 8, 2022, to November 3, 2023.

Main Outcomes and Measures

Item rankings from phase I participants were used to narrow the original 61-item survey down to 45 items in the phase II survey. To assess construct validity, an exploratory factor analysis was performed. Cronbach α and pairwise Pearson correlation coefficients were used to measure internal consistency, reliability, and redundancy. Test-retest reliability was evaluated using intraclass correlation coefficients.

Results

Phase I enrolled 38 individuals, of whom 30 completed the survey (15 women [60%]; 21 participants [84%] aged >40 years). Phase II enrolled 342 participants, of whom 317 completed the survey (305 women [89%]; 284 participants [83%] aged >40 years). A total of 42 items across 7 domains were selected based on exploratory factor analysis. After Cronbach α and pairwise correlation analysis, 33 items across 6 multi-item domains and 2 standalone items were incorporated into the final QOL instrument. Cronbach αs for each of the final 6 domains were at least 0.77, suggesting excellent internal validity. Pairwise correlations did not show strong correlations (ie, none ≥0.80), suggesting minimal redundancy between domains. Younger age was significantly associated with a lower global score. Participants with malignant tumors scored lower on 4 of the 6 multi-item domains. Test-retest reliability coefficients for the domains ranged from 0.82 to 0.93, indicating very good reproducibility over a 2-week interval.

Conclusions and Relevance

These findings suggest the Parotidectomy Quality of Life Index demonstrated excellent internal validity and test-retest reliability. With further external validation, this instrument may provide opportunity for quality improvement in clinical practice and has potential as a key patient-reported outcome in future parotidectomy clinical trials.

Efficiency Analysis of Hemostatic Agents in Drainless Neck Surgery: Cellulose-Based Versus Liquid Fibrin Sealants

PURPOSE

 Using liquid fibrin sealants has once again questioned the benefit of drain placement in head and neck operations. Cellulose-based hemostats offering different hemostasis mechanisms have scarcely been investigated in drainless neck surgeries. This study aimed to evaluate whether liquid fibrin sealant offers any advantage over cellulose-based hemostats in various head and neck surgeries.

METHODS

A prospective trial of patients who underwent various neck surgeries between 2020 and 2022. Baseline characteristics and postoperative outcomes were compared between the drain-placed and the drainless groups, with the latter sub-categorized into three groups: fibrin sealant, cellulose-based hemostats, and a combination of both.

RESULTS

A total of 119 patients were included (63 thyroidectomies, 40 parathyroidectomies, and 16 sialoadenectomies). Fifty eight had a drain placed and 61 had no drain. In the drainless group, 23 patients received cellulose-based absorbable hemostats (SURGICEL®/ FIBRILLAR™); 18 patients had fibrin sealants (EVICEL®/TachoSil®/TISSEEL); in 16, a combination of both was used; and in four patients, no hemostatic agent was used. Three (5%) of the 61 drainless patients developed a seroma compared to one (2%) seroma in the drain-placed patients. No advantage was demonstrated using a combination of FIBRILLAR™ with a fibrin sealant nor for any used separately. Drain placement delayed patient discharge by at least one day compared to the group without a drain (p < 0.001).

CONCLUSION

Drain placement offered a minor advantage in the postoperative course reducing rates of seroma formation, while delaying patient discharge by at least one day. There was no advantage in using a specific hemostatic agent over the other.

Drainless, day-case lateral neck dissection with Artiss™ fibrin sealant: A prospective cohort study

OBJECTIVE

Lateral neck dissection (LND) is performed for staging/treatment of head and neck lesions. This traditionally includes placement of a drain and inpatient admission. Drainless, day-case head and neck surgery is attractive due to cost-effectiveness and reduced length of stay, but evidence is lacking in LND. We aim to investigate Artiss™ as an alternative to drain placement, facilitating day-case LND.

METHODS

A prospective review was conducted of patients who underwent LND in a UK hospital over a 22-month period.

RESULTS

Thirty-nine patients were identified (27 Artiss™ only; 12 Artiss™ with a drain). Eight Artiss™ only patients were day-case. All drains were removed by post-operative day 2. There was no statistically significant difference in the number of complications between the two groups.

CONCLUSION

This observational study demonstrates that for selected patients, Artiss™ could facilitate drainless, day-case LND. Further controlled studies with matched groups and larger numbers are required to validate this.
