Identifying Factors of Operative Efficiency in Head and Neck Free Flap Reconstruction

Importance

Head and neck oncological resection and reconstruction is a complex process that requires multidisciplinary collaboration and prolonged operative time. Numerous factors are associated with operative time, including a surgeon's experience, team familiarity, and the use of new technologies. It is paramount to evaluate the contribution of these factors and modalities on operative time to facilitate broad adoption of the most effective modalities and reduce complications associated with prolonged operative time.

Objective

To examine the association of head and neck cancer resection and reconstruction interventions with operative time.

Design, Setting, and Participants

This large cohort study included all patients who underwent head and neck oncologic resection and free flap-based reconstruction in Calgary (Alberta, Canada) between January 1, 2007, and March 31, 2020. Data were analyzed between November 2021 and May2022.

Interventions

The interventions that were implemented in the program were classified into team-based strategies and the introduction of new technology. Team-based strategies included introducing a standardized operative team, treatment centralization in a single institution, and introducing a microsurgery fellowship program. New technologies included use of venous coupler anastomosis and virtual surgical planning.

Main Outcomes and Measures

The primary outcome was mean operative time difference before and after the implementation of each modality. Secondary outcomes included returns to the operating room within 30 days, reasons for reoperation, returns to the emergency department or readmissions to hospital within 30 days, and 2-year and 5-year disease-specific survival. Multivariate regression analyses were performed to examine the association of each modality with operative time.

Results

A total of 578 patients (179 women [30.9%]; mean [SD] age, 60.8 [12.9] years) undergoing 590 procedures met inclusion criteria. During the study period, operative time progressively decreased and reached a 32% reduction during the final years of the study. A significant reduction was observed in mean operative time following the introduction of each intervention. However, a multivariate analysis revealed that team-based strategies, including the use of a standardized nursing team, treatment centralization, and a fellowship program, were significantly associated with a reduction in operative time.

Conclusions

The results of this cohort study suggest that among patients with head and neck cancer, use of team-based strategies was associated with significant decreases in operative time without an increase in complications.

Immobilization of the Wrist After Dorsal Wrist Ganglion Excision: A Systematic Review and Survey of Current Practice

BACKGROUND

Postoperative care after dorsal wrist ganglion (DWG) excision is highly varied. The effect of immobilization of the wrist on patient outcomes has not yet been examined.

METHODS

A systematic review of the literature was performed to determine whether wrist immobilization after DWG surgical excision is beneficial. A survey of hand surgeons in Canada was performed to sample existing practice variations in current immobilization protocols after DWG excision.

RESULTS

A systematic review yielded 11 studies that rigidly immobilized the wrist (n = 5 open excision, n = 5 arthroscopic excision, n = 1 open or arthroscopic excision), 10 studies that used dressings to partially limit wrist motion (n = 5 open, n = 5 arthroscopic), 1 study (open) that did either of the above, and 2 studies (arthroscopic) that did not restrict wrist motion postoperatively. This ranged from 48 hours to 2 weeks in open DWG excision and 5 days to 3 weeks in arthroscopic DWG excision. The survey of Canadian hand surgeons had a similarly divided result of those who chose to immobilize the wrist fully (41%), partially (14%), or not at all (55%). Most surgeons surveyed who immobilized the wrist postoperatively did so for 1 to 2 weeks.

CONCLUSION

The systematic review and survey of Canadian hand surgeons reveal that hand surgeons are divided regarding the need to immobilize the wrist after DWG excision. In terms of functional outcome, there is no compelling data to suggest 1 strategy is superior. The time frame for immobilization when undertaken was short at 2 weeks or less.The systematic review is registered in the PROSPERO database (PROSPERO 2016:CRD42016050877).

Use of an Omental Flow-Through Flap for Recipient Vessels in the Reconstruction of a Lumbar Spine Defect: A Case Report

CASE

Spine reconstruction after en bloc spondylectomy is challenging and may require multidisciplinary intervention. En bloc spine tumor resection with embolization of local recipient vessels for tumor control limits reconstructive options. Herein, we describe a case where combined efforts from orthopaedic, general, and plastic surgery teams permitted the successful reconstruction of a multilevel lumbar vertebral defect.

CONCLUSION

A fibula-free flap within a titanium cage construct anastomosed to the left gastroepiploic vessels via a pedicled omental flow-through flap is a viable and novel method for reconstruction of a multilevel vertebral defect.

The success of salvage procedures for failing digital replants: A retrospective cohort study

BACKGROUND

The success of salvage procedures for failing digital replants (FR) is poorly documented. We sought to evaluate the success of salvage procedures for FR and factors contributing to successes and failures of replants.

METHODS

Adult patients who presented to our center between January 1, 2000 and December 31, 2015, suffered ≥1 digital amputation(s), and underwent digital replantation were included. Preoperative, perioperative, and postoperative details were recorded. Digits were monitored postoperatively via nursing and physician assessments. The presumed reason for failure, details, and outcomes of salvage attempts were recorded for FR. Length of hospital stay and complications were also recorded.

RESULTS

Fifty-two patients and 83 digits were included. Fifty-two digits (63%) were compromised (arterial ischemia in 15 digits; venous congestion in 37 digits) and 48 digits had salvage therapy. Twenty-one FR (44%) were salvaged via operative (1 of 2; 50%), nonoperative (19 of 43; 44%), and combined (1 of 3; 33%) therapies. FR patients were more likely than those with successful replants to receive a blood transfusion (52 vs. 23%; p = .009) with more transfused units (3.45 ± 3.30 vs. 0.86 ± 0.95; p = .001). Length of stay was prolonged for FR patients (9 [range: 2-22] vs. 7 [range: 3-19] days; p = .039). Ultimately, 59% (49 of 83) of replants were successful, where 25% (21 of 83) were successfully salvaged.

CONCLUSION

Nonoperative and operative salvage therapies improve the rate of replant survival. We suggest close postoperative monitoring of all replants and active salvage interventions for compromised replants in the postoperative period.

Compliance with published recommendations for postoperative antibiotic management of children with appendicitis: A chart audit

BACKGROUND

Recommendations for postoperative antibiotics for appendicitis were published by the American Pediatric Surgical Association (APSA) in 2010. However, implementation of practice recommendations often takes years. We measured compliance of pediatric surgeons (who receive reminders every 6months from the Division Chief) with the APSA recommendations.

METHODS

With Research Ethics Board approval, we completed a retrospective review of children who underwent appendectomy since 2010. Compliance with APSA recommendations was analyzed descriptively. Agreement between pediatric surgeons and pathologists was analyzed by kappa.

RESULTS

We reviewed 242 charts. Patients were excluded for missing data (n=5) and diagnosis other than appendicitis (n=27), resulting in 210 patients with appendicitis (119 acute, 91 perforated). Agreement of perforation status between surgeons and pathologists was good (κ=0.75; 95% CI: 0.66-0.83). Many patients with nonperforated appendicitis received antibiotics in excess of the APSA recommendations (62/119 (52%)), as did those with uncomplicated perforated appendicitis (52/84 (62%)).

CONCLUSIONS

Despite the availability of published recommendations, surgeons continue to prescribe postoperative antibiotics for appendicitis in excess of the recommendations. Overtreatment leads to potential medication errors and increased length-of-stay/medication costs. An intensive implementation program with ongoing education/monitoring may improve compliance with established recommendations to decrease the use of excess postoperative antibiotics and their associated costs/risks.

Messages for men: the efficacy of EPPM-based messages targeting men's physical activity

OBJECTIVE

The majority of men are insufficiently active. Men's tendencies to participate in risky behaviors and their inactivity likely contribute to their increased risk of morbidity and mortality. Physical activity decreases the risk of developing many chronic diseases and may be an optimal behavior to target in men's health interventions. However, educational resources promoting physical activity for men are lacking. To address this gap, we tested the efficacy of messages based upon the Extended Parallel Process Model (EPPM; Witte, 1992) to increase men's physical activity intentions and behaviors.

METHOD

Men who were not meeting physical activity guidelines (n = 611) were randomly assigned to read high or low efficacy physical activity messages paired with high or no health risk information. Participants read four brief messages on four consecutive days. Intentions were assessed at baseline and the first follow-up (Day 5). Manipulation check measures were assessed at Day 5. Behavior was assessed at baseline and the second follow-up (Day 14).

RESULTS

Overall, the messages had small sized effects. A completer analysis revealed that although men's intentions to be active increased over the course of the study regardless of the messages they received, only men who received risk information significantly increased their physical activity. Men who received low efficacy and risk information were less likely to meet the physical activity guidelines at Day 14 than men who only received low efficacy information.

CONCLUSIONS

From these results, we suggest preliminary recommendations for the development of physical activity messages for men and areas for future EPPM-based research.
