RESUMO
BACKGROUND: Endoluminal functional impedance planimetry and panometry assesses secondary peristalsis in response to volumetric distention under sedation. We hypothesize that impedance planimetry and panometry can replace high-resolution manometry in the preoperative assessment prior to anti-reflux surgery. METHODS: Single institution prospective data were collected from patients undergoing anti-reflux surgery between 2021 and 2023. A 16-cm functional luminal imaging probe (FLIP) assessed planimetry and panometry prior to surgery under general anesthesia at the start of each case. Panometry was recorded and esophageal contractile response was classified as normal (NCR), diminished or disordered (DDCR), or absent (ACR) in real time by a single panometry rater, blinded to preoperative HRM results. FLIP results were then compared to preoperative HRM. RESULTS: Data were collected from 120 patients, 70.8% female, with mean age of 63 ± 3 years. There were 105 patients with intraoperative panometry, and 15 with panometry collected during preoperative endoscopy. There were 60 patients (50%) who had peristaltic dysfunction on HRM, of whom 57 had FLIP dysmotility (55 DDCR, 2 ACR) resulting in 95.0% sensitivity. There were 3 patients with normal secondary peristalsis on FLIP with abnormal HRM, all ineffective esophageal motility (IEM). No major motility disorder was missed by FLIP. A negative predictive value of 91.9% was calculated from 34/37 patients with normal FLIP panometry and normal HRM. Patients with normal HRM but abnormal FLIP had larger hernias compared to patients with concordant studies (7.5 ± 2.8 cm vs. 5.4 ± 3.2 cm, p = 0.043) and higher preoperative dysphagia scores (1.5 ± 0.7 vs. 1.1 ± 0.3, p = 0.021). CONCLUSION: Impedance planimetry and panometry can assess motility under general anesthesia or sedation and is highly sensitive to peristaltic dysfunction. Panometry is a novel tool that has potential to streamline and improve patient care and therefore should be considered as an alternative to HRM, especially in patients in which HRM would be inaccessible or poorly tolerated.

INTRODUCTION: To determine if treatment and clinical outcomes of adrenocortical carcinoma (ACC) vary by race and insurance status. METHODS: ACC patients from the National Cancer Database (2004-2017) were reviewed. Race was defined as White versus minority (Black and Hispanic). Insurance types were private (PI) versus other (Medicaid/uninsured/unknown). Metastatic ACC (M-ACC) was defined as distant metastases at the time of diagnosis; nonmetastatic ACC (NM-ACC) patient had no distant disease. RESULTS: Of 2351 NM-ACC patients, 83.6% were White and 16.4% minority. There were 1216 M-ACC patients, with 80.3% White and 19.8% minority. Both White NM-ACC and M-ACC patients had more PI (each P < 0.001). PI NM-ACC was associated with a shorter duration from diagnosis to first treatment (14 versus 18 d, P = 0.005). Both NM-ACC and M-ACC with PI were more likely to receive surgery (92.6% versus 86.9%, P = 0.001 and 35.4% versus 27%, P = 0.02) and to receive surgery sooner (13 versus 16 d, P = 0.03). M-ACC with PI were more likely to receive chemotherapy (63.6% versus 54.3%, P = 0.01) and to have lymph nodes examined (14.8% versus 8.6%, P = 0.02). Length of stay postoperatively was shorter for White NM-ACC (6 versus 7 d, P = 0.04) and M-ACC (8 versus 17 d, P = 0.02). For NM-ACC and M-ACC, the 30-d readmission, 90-d mortality, and overall survival were similar by race. A multivariable analysis showed minorities (OR 0.69, 95% confidence interval 0.54-0.88, P = 0.003) and patients without PI (OR 0.75, 95% confidence interval 0.58-0.97, P = 0.03) were less likely to have surgery. However, a multivariable analysis showed survival was similar for White versus minority patients and PI versus other. CONCLUSIONS: White NM-ACC or M-ACC and PI were more likely to receive surgery and timely multimodality care. These disparities were not associated with differences in 90-d mortality or overall survival.

OBJECTIVE: To determine exposure rates to antibiotics prior to radical cystectomy and determine if there is correlation with post-operative infections. METHODS AND MATERIALS: 2248 patients were identified in the 2016 SEER-Medicare linkage who underwent radical cystectomy between 2008 and 2014 with complete prescription information. An outpatient prescription for an antibiotic within 30 days prior to cystectomy was considered exposure. Antibiotic class and combinations were recorded. Postoperative infectious diagnoses and readmissions were tabulated within 30 days of cystectomy. RESULTS: Fifty one percent of patients (n = 1149) were prescribed an outpatient antibiotic prior to cystectomy. Patients receiving antibiotics were more likely to be female (31% vs 25%, P < .01) and had been diagnosed with an infection (17% vs 11%, P < .01). Antibiotic bowel prophylaxis was prescribed to 42% of patients receiving antibiotics. Postoperatively, the exposure group had higher rates of any infection, (56% vs 51% P < .01) and UTI (36% vs 31% P < .01). All-cause readmission within 30 days was higher in the exposure cohort (26% vs 22%, P = .02) Multivariable logistic regression showed outpatient preoperative antibiotics were an independent risk factor for any infection (HR 1.19, P < .05) and readmission (hazards ratio 1.24, P = .03) in the 30 days after radical cystectomy. CONCLUSION: Outpatient antibiotic use prior to radical cystectomy is common and may be associated with increased risk of postoperative infection and readmission. Antibiotic use prior to radical cystectomy should be examined as a modifiable factor to decrease post-operative morbidity.

BACKGROUND: Simulation using virtual reality (VR) simulators is an important tool in surgical training. VR laparoscopic simulators can provide immediate objective performance assessment without observer evaluation. This study aims to explore the correlation between subjective observer evaluation and VR laparoscopic simulator performance metrics in a laparoscopic cholecystectomy (LC) simulation module. METHODS: A LC simulation module using a VR laparoscopic simulator was completed by PGY2-3 general surgery residents at a single institution. Simulation performance was recorded and evaluated by a trained evaluator using the validated Global Operative Assessment of Laparoscopic Skills (GOALS) form, the Objective Structured Assessment of Technical Skills (OSATS) form, and a LC-specific simulation assessment form (LC-SIM). Objective performance metrics were also obtained from the simulator system. Performance before the curriculum (pre-test) and after the curriculum (post-test) were compared. RESULTS: Fourteen residents were included in the study. There were significant improvements from pre-test to post-test on each component of GOALS, OSATS, and LC-SIM scores (all p values < 0.05). In terms of objective simulator metrics, significant improvements were noted in time to extract gallbladder (481 ± 221 vs 909 ± 366 min, p = 0.019), total number of movements (475 ± 264 vs 839 ± 324 min, p = 0.012), and total path length (955 ± 475 vs 1775 ± 632 cm, p = 0.012) from pre-test to post-test. While number of movements and total path lengths of both hands decreased, speed of right instrument also decreased from 4.1 + 2.7 to 3.0 ± 0.7 cm/sec (p = 0.007). Average speed of left instrument was associated with respect for tissue (r = 0.60, p < 0.05) and depth perception (r = 0.68, p < 0.05) on post-test evaluations. CONCLUSION: Our study demonstrated significant improvement in technical skills based on subjective evaluator assessment as well as objective simulator metrics after simulation. The few correlations identified between the subjective evaluator and the objective simulator assessments suggest the two evaluation modalities were measuring different aspects of the technical skills and should both be considered in the evaluation process.

Importance: The National Comprehensive Cancer Network recommends imaging within 6 months after treatment for head and neck cancer (HNC). Further imaging is recommended only if the patient has symptoms or abnormal findings on physical examination. However, in many instances, asymptomatic patients continue to have imaging evaluations. Objectives: To assess practice patterns in surveillance imaging in patients with HNC and evaluate the costs associated with these imaging practices. Design, Setting, and Participants: This single-institution retrospective economic evaluation study screened 435 patients to identify patients newly diagnosed with head and neck mucosal and salivary gland malignant tumors between January 1, 2010, and December 31, 2016. Data analyses were performed from October 25, 2018, to November 24, 2020. Exposure: Imaging practice patterns. Main Outcomes and Measures: Number and costs of imaging studies during the surveillance period for all patients, patients who remained disease free, and patients who developed recurrence. Results: A total of 136 patients (mean [SD] age at diagnosis, 62 [14] years; 84 [61.8%] male; 106 [77.9%] White) with HNC were included in the study. The oropharynx was the most common subsite (64 [47.1%]), most HNCs were stage IVA (62 [45.6%]), and most patients received definitive radiation-based treatment (71 [52.2%]). During the median surveillance period of 3.2 years (range, 0.3-6.8 years), a mean (SD) of 14 (10) imaging studies were performed for all patients, with a mean (SD) total cost of $36â¯800 ($24â¯500). In patients who remained disease free, a mean (SD) of 13 (10) imaging studies were performed during the surveillance period, with a mean (SD) total cost of $35â¯000 ($21â¯700). Patients who lacked symptoms had a mean (SD) of 4 (3) studies performed per year, resulting in a mean cost of $9600 ($5900) per year. Patients who developed recurrence had more studies per year of follow-up (mean difference, 5.0; 95% CI, 3.4-6.6) and higher associated mean costs (mean difference, $10â¯600; 95% CI, $6100-$15â¯000) than patients who remained disease free. Conclusions and Relevance: In this economic evaluation study, many patients treated for HNCs received imaging studies beyond what is recommended by National Comprehensive Cancer Network guidelines. These findings suggest that the cost burden of imaging in the asymptomatic patient needs to be considered against the value obtained from routine imaging in this current health care environment.

BACKGROUND: Peroral endoscopic myotomy (POEM) has previously been shown to be equally if not more expensive than laparoscopic Heller myotomy (LHM). We compare perioperative outcomes and charges between POEM and LHM at a single institution. METHODS: Outcomes and charge data of 33 patients who underwent LHM and 126 patients who underwent POEM were analyzed. Patients who did not present electively were excluded. RESULTS: There were no demographic differences between groups. Patients who underwent POEM had a significantly shorter mean operative time and median length of stay (both p < 0.001). Patients who underwent POEM stopped narcotics earlier and had faster return to activities of daily living (both p < 0.05). When adjusted for inflation, POEM incurred less in hospital charges than LHM (35.5 ± 12.8 vs 30.7 ± 10.3 in thousands of US dollars, p = 0.006). CONCLUSIONS: Patients who underwent POEM compared to LHM had significantly better perioperative outcomes. Our results suggest POEM may be the more cost-effective option.

The scalable delivery of genomic medicine requires collaboration between genetics and non-genetics providers. Thus, it is essential to investigate and address the perceived value of and barriers to incorporating genetic testing into the clinical practice of primary care providers (PCPs). We used a mixed-methods approach of qualitative interviews and surveys to explore the experience of PCPs involved in the pilot DNA-10K population genetic testing program. Similar to previous research, PCPs reported low confidence with tasks related to ordering, interpreting and managing the results of genetic tests, and identified the need for additional education. PCPs endorsed high levels of utility for patients and their families but noted logistical challenges to incorporating genetic testing into their practice. Overall PCPs were not familiar with the United States' Genetic Information Nondiscrimination Act and they expressed high levels of concern for patient data privacy and potential insurance discrimination. This PCP feedback led to the development and implementation of several processes to improve the PCP experience with the DNA-10K program. These results contribute to the knowledge base regarding genomic implementation using a mixed provider model and may be beneficial for institutions developing similar clinical programs.
RESUMO
IMPORTANCE: Evaluation of distant metastasis (DM) is part of every new cancer evaluation. Understanding DM presentation patterns may impact the imaging workup of Head and Neck Squamous Cell Carcinoma (HNSCC). OBJECTIVE: Examine the frequency and location of DM at presentation in HNSCC. We hypothesize that DM are rare, and the lung is the most common site for DM. Secondary evaluation includes identifying patient and tumor factors predictive of DM, and the implications for selection of workup imaging. DESIGN: Data from the National Cancer Data Base (NCDB) from 2010 to 2015 were analyzed. Subsites evaluated included oral cavity, oropharynx, larynx, hypopharynx, and nasopharynx. Sites of distant metastasis were evaluated in available cases and analyzed. SETTING: Population based database study. RESULTS: 151,730 cases were available for analysis. Nasopharynx had the highest percentage of M1 disease (9.1%) followed by hypopharynx (7.3%). Excluding the nasopharynx (NP), 3.1% of cases were reported as M1. Advanced T-stage, positive N-stage, and N3 status were all predictors of M1 status on univariate and multivariate analysis for all subsites (Pâ¯<â¯0.05). Where site of metastasis was available, most (53.1%) DM cases presented with at least lung involvement. In nasopharynx cancers, only 32.8% of DM included the lung. CONCLUSIONS AND RELEVANCE: Distant metastasis in HNSCC are rare events. PET/CT offers many advantages, but for routine distant metastasis evaluation in HNSCC, CT scan of the chest may be more cost-effective.

BACKGROUND AND OBJECTIVES: The purpose of this study was to determine charges following unilateral mastectomy (UM) and bilateral mastectomy (BM) for patients with unilateral breast cancer (UBC). We hypothesized that BM may be associated with fewer charges over time. METHODS: A retrospective review was conducted of patients with UBC treated between 2006 and 2010 with UM and BM in a large healthcare system. Institutional billing data were investigated for 5 years postoperatively to calculate the immediate and subsequent charges of all inpatient and outpatient breast-related care associated with the initial diagnosis for a subset of patients identified using propensity score matching method. RESULTS: A subset of matched patients (n = 320) undergoing UM (n = 160) or BM (n = 160) were included in this analysis. At 1 year, there was a trend toward lower total charges following UM as compared with BM (median, $125 230 vs $138 467; P = .6075). However, during years 2 to 5, total charges were significantly higher following UM vs BM ($22 128 vs $13 478; P = .0116). CONCLUSIONS: While initially higher, overall charges for BM are lower than UM between 2 and 5 years out from surgery. Further study is necessary to determine if this trend is sustained over the long term. These data can inform patient decision making regarding mastectomy for their breast cancer.

PURPOSE: To assess population-based trends in artificial urinary sphincter (AUS) placement after prostatectomy and determine the effect of timing on device survival and complications. METHODS: We identified patients who underwent prostatectomy and AUS placement in SEER-Medicare from 2002 to 2011. We analyzed factors affecting the time of reoperation from AUS implantation and prostatectomy using multivariable Cox proportional hazard models. RESULTS: In total, 841 men underwent AUS placement at a median 23 months after prostatectomy. Patients who underwent reoperation (28.5%) had higher clinical stage, more likely underwent open prostatectomy, or had prior sling placement (p < 0.03). There were no differences in rates of diabetes, smoking status, prior radiation therapy, or Charlson Comorbidity Index between those requiring reoperation vs. not (all p > 0.15). Patients with AUS placement > 15 months after prostatectomy (75%) initially experienced less need for operative reinterventions. Patients with later AUS placement were significantly more likely to have received radiation therapy [22.9 vs. 3.8% (p < 0.01)]. Nonetheless, late implantation was confirmed to be protective on multivariate analysis during the first 5 years after AUS placement [HR 0.79 (95% CI 0.67-0.92); p < 0.01]. Factors independently associated with a shorter interval time until reoperation included history of radiation [HR 1.93 (95% CI 1.33-2.80); p < 0.01] and history of prior sling [HR 1.70 (95% CI 1.08-2.68); p = 0.02]. Even for patients who underwent radiation therapy, delayed AUS implantation reduced reoperative risk. CONCLUSIONS: Late AUS implantation in the Medicare population is associated with prolonged device survival initially, while radiation and prior sling surgery predict for earlier reoperation. Patients with delayed AUS implantation experience less immediate complications. Further work is required to identify patient-specific factors which may explain variability in timing for AUS.
