Variance in 3D anatomic localization of surgical margins based on conventional margin labeling in head and neck squamous cell carcinoma.

OBJECTIVE: In head and neck cancer (HNC), positive margins are strongly predictive of treatment failure. We sought to measure the accuracy of localization of margin sampling sites based on conventional anatomic labels using a digital 3D-model. METHODS: Preoperative CT scans for 9 patients with HNC treated operatively at our institution were imported into a multiplanar radiology software, which was used to render a digital 3D model of each tumor intended to represent the resection specimen. Surgical margin labels recorded during the operative case were collected from pathology records. Margin labels (N = 64) were presented to participating physicians.Participants were asked to mark the anatomic location of each surgical margin using the 3D-model and corresponding radiographic planes for reference.For each individual margin, the 3D coordinates of each participant's marker were used to calculate a mean localization point called the geometric centroid. Mean distance from individual markers to the centroid was compared between participantsand margin types. RESULTS: Amongst 7 surgeons, markers were placed a mean distance of 12.6 mm ([SD] = 7.5) from the centroid.Deep margins were marked with a greater mean distance than mucosal/skin margins (19.6 [24.8] mm vs. 15.3 [14.9] mm, p = 0.034). When asked to relocate a margin following re-resection, surgeons marked a point an average of 20.6 [12.4] mm from their first marker with a range of 3.9- 45.1 mm. CONCLUSIONS: Retrospective localization of conventionally labeled margins is an imprecise process with variability across the care team. Future interventions targeting margin documentation and communication may improve sampling precision.

Retrograde Cricopharyngeus Dysfunction: The Jefferson Experience.

OBJECTIVES: To describe our center's experience with the identification and treatment of retrograde cricopharyngeus dysfunction (R-CPD), a syndrome involving the inability to belch previously described by only one institution. Additionally, because all patients initially learned of their condition and sought treatment as a result of social media posts, we queried their source and comfort with this form of medical referral. METHODS: Retrospective chart review of patients who underwent botulism toxin injection into the cricopharyngeus muscle for treatment of R-CPD from 2019 to 2022. Demographic data, most common symptoms at presentation, and response to treatment and complications were documented. Post-treatment questionnaires were reviewed. RESULTS: A total of 85 patients were identified. Mean age at surgery was 27 years. There were 54 (63.5%) females and 31 (36.5%) males. The inability to burp (98.8%), bloating (92.9%), gurgling noises (31.8%), and excessive flatulence (21.2%) were the most common symptoms. The minimum units of botox utilized were 25, whereas the maximum was 100. The majority of patients (88.2%) had a successful response at initial follow-up visit. The most common complication was mild dysphagia (30.6%), which was transient for all patients. Most patients learned of our practice through social media, with only one patient being referred by a medical provider. CONCLUSIONS: The majority of patients in our cohort were young and female. The inability to burp and bloating were the most common presenting symptoms. Social media was the primary source of referral. Our institution favors 80-100 units for an effective response.

Characteristics and Outcomes of Patients Discharged Directly Home From a Medical Intensive Care Unit: A Retrospective Cohort Study.

OBJECTIVE: To evaluate the safety of directly discharging patients home from the medical intensive care unit (MICU). MATERIALS AND METHODS: Single-center retrospective observational study of consecutive MICU direct discharges to home from an urban university hospital between June, 1, 2017, and June 30, 2019. RESULTS: Of 1061 MICU discharges, 331 (31.2%) patients were eligible for analysis. Patients were divided into 2 groups based on duration of wait-time (< or ≥24 hours) between ward transfer order and ultimate hospital discharge. Most patients (68.2%) were discharged in <24 hours. Patients who waited for a floor bed for ≥24 hours prior to discharge had longer hospital length-of-stay (LOS, median 3.83 versus 2.00 days) and ICU LOS (median 3.51 versus 1.74 days). Overall, 44 (13.3%) direct MICU discharges were readmitted to the hospital within 30-days, but there was no difference in this outcome or in 30-day mortality when comparing the 2 wait-time groups. CONCLUSIONS: The practice of directly discharging MICU patients home does not negatively influence patient outcomes. Patients who overstay in the ICU after being deemed transfer-ready are unlikely to be benefiting from critical care, but impact hospital throughput and resource utilization. Prospective investigation into this practice may provide further confirmation of its feasibility and safety.
