Advances in Diagnostic, Staging, and Restaging Evaluation of Esophageal and Gastric Cancer.

The initial endoscopic and staging evaluation of esophagogastric cancers must be accurate and comprehensive in order to select the optimal therapeutic plan for the patient. Esophageal and gastric cancers (and treatment paradigms) are delineated by their proximity to the cardia (within 2 cm). The most frequent and important symptom that informs the initial staging evaluation is dysphagia, which is associated with at least cT3 or locally advanced disease. Endoscopic ultrasound is often needed if earlier stage disease is suspected, preferably in combination with endoscopic mucosal or submucosal resection or fine-needle aspiration of suspicious lymph nodes to enhance staging accuracy.

Treatment of esophageal adenocarcinoma in patients with a history of bariatric surgery.

BACKGROUND: The relationship among obesity, bariatric surgery, and esophageal adenocarcinoma (EAC) is complex, given that some bariatric procedures are thought to be associated with increased incidence of reflux and Barrett's esophagus. Previous bariatric surgery may complicate the use of the stomach as a conduit for esophagectomy. In this study, we presented our experience with patients who developed EAC after bariatric surgery and described the challenges encountered and the techniques used. METHODS: We conducted a retrospective review of our institutional database to identify all patients at our institution who were treated for EAC after previously undergoing bariatric surgery. RESULTS: In total, 19 patients underwent resection with curative intent for EAC after bariatric surgery, including 10 patients who underwent sleeve gastrectomy. The median age at diagnosis of EAC was 63 years; patients who underwent sleeve gastrectomy were younger (median age, 56 years). The median time from bariatric surgery to EAC was 7 years. Most patients had a body mass index (BMI) score of >30 kg/m2 at the time of diagnosis of EAC; approximately 40% had class III obesity (BMI score > 40 kg/m2). Six patients (32%) had known Barrett's esophagus before undergoing a reflux-increasing bariatric procedure. Sleeve gastrectomy patients underwent esophagectomy with gastric conduit, colonic interposition, or esophagojejunostomy. Only 1 patient had an anastomotic leak (after esophagojejunostomy). CONCLUSION: Endoscopy should be required both before (for treatment selection) and after all bariatric surgical procedures. Resection of EAC after bariatric surgery requires a highly individualized approach but is safe and feasible.

Improved Preoperative Risk Assessment Tools Are Needed to Guide Informed Decision Making before Esophagectomy.

OBJECTIVE: We sought to evaluate the performance of 2 commonly used prediction models for postoperative morbidity in patients undergoing open and minimally invasive esophagectomy. SUMMARY BACKGROUND DATA: Patients undergoing esophagectomy have a high risk of postoperative complications. Accurate risk assessment in this cohort is important for informed decision-making. METHODS: We identified patients who underwent esophagectomy between January 2016 and June 2018 from our prospectively maintained database. Predicted morbidity was calculated using the American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator (SRC) and a 5-factor National Surgical Quality Improvement Programderived frailty index. Performance was evaluated using concordance index (C-index) and calibration curves. RESULTS: In total, 240 consecutive patients were included for analysis. Most patients (85%) underwent Ivor Lewis esophagectomy. The observed overall complication rate was 39%; the observed serious complication rate was 33%.The SRC did not identify risk of complications in the entire cohort (C-index, 0.553), patients undergoing open esophagectomy (C-index, 0.569), or patients undergoing minimally invasive esophagectomy (C-index, 0.542); calibration curves showed general underestimation. Discrimination of the SRC was lowest for reoperation (C-index, 0.533) and highest for discharge to a facility other than home (C-index, 0.728). Similarly, the frailty index had C-index of 0.513 for discriminating any complication, 0.523 for serious complication, and 0.559 for readmission. CONCLUSIONS: SRC and frailty index did not adequately predict complications after esophagectomy. Procedure-specific risk-assessment tools are needed to guide shared patient-physician decision-making in this high-risk population.

Early Ambulation is Associated with Improved Outcomes Following Colorectal Surgery.

BACKGROUND: The Enhanced Recovery After Surgery (ERAS) society lists early mobilization as one of their recommendations for improving patient outcomes following colorectal surgery. The level of supporting evidence, however, is relatively weak, and furthermore, the ERAS guidelines do not clearly define "early" mobilization. In this study, we define mobilization in terms of time to first ambulation after surgery and develop an outcome-based cutoff for early mobilization. METHODS: This is a retrospective cohort study comprised of 291 patients who underwent colorectal operations at a large, academic medical center from June to December 2019. Three cutoffs (12 hours, 24 hours, and 48 hours) were used to divide patients into early and late ambulation groups for each cutoff, and statistical analysis was performed to determine differences in postoperative outcomes between the corresponding groups. RESULTS: Multivariate analysis showed no difference between the early and late ambulation groups for the 12-hour and 48-hour cutoffs; however, ambulation before 24 hours was associated with a decreased rate of severe complications as well as fewer adverse events overall. Patients who ambulated within 24 hours had a 4.1% rate of severe complications and a 22.1% rate of experiencing some adverse event (complication, return to the emergency department, and/or readmission). In comparison, 11.8% of patients who ambulated later experienced a severe complication (P = 0.026), while 36.1% of patients experienced some adverse event (P = 0.011). CONCLUSIONS: Ambulation within 24 hours after colorectal surgery is associated with improved postoperative outcomes, particularly a decreased rate of severe complications.

Surgeon Bias in Postoperative Opioid Prescribing.

BACKGROUND: The misuse of opioids is a serious national crisis that is fueled by prescriptions medications. Opioid prescribing habits are known to be highly varied amongst providers. The purpose of this study is to identify patient and surgeon characteristics that predict postoperative opioid prescribing patterns. METHODS: This is a serial cross-sectional analysis of 20,497 patients who underwent general surgical procedures at a large academic center. Our primary outcome was the total amount of opioids prescribed within 30 days of the surgery. Univariate and multivariate linear regression models were used to identify patient and provider characteristics that were associated with increased opioids prescribed. RESULTS: Among patient characteristics studied, patient age, sex, ethnicity, and insurance status were found to have a significant association with the amount of opioids prescribed. Younger patients and male patients received higher morphine milligram equivalents (MMEs) on discharge (p < 0.05). Patients of Hispanic background were prescribed significantly lower opioids compared to Non-Hispanic patients (p < 0.0001). Among the provider characteristics studied, surgeon sex and years in practice were significantly predictive of the amount of opioids prescribed, with surgeons in practice for <15 years prescribing the highest MMEs (p < 0.0001). CONCLUSION: While opioid prescribing habits after surgery seem highly varied and arbitrary, we have identified key predictors that highlight biases in surgeon opioid prescribing patterns. Surgeons tend to prescribe significantly larger amounts of opioids to younger, male patients and those of certain ethnic backgrounds, and surgeons with fewer years in practice are more likely to prescribe more opioids.

Synchronous Esophageal and Lung Cancers-Is Combined Anatomic Resection Appropriate?

BACKGROUND: This study evaluated the safety and feasibility of combined resection for patients with synchronous pulmonary and esophageal cancer. METHODS: Patients undergoing esophagectomy between 1997 and 2019 were identified from prospectively collected databases at 3 tertiary referral centers, and those with combined anatomic lung resection at the same setting were matched in a 1:3 ratio to esophagectomy-alone patients, based on age, sex, pathologic stage, neoadjuvant therapy, and surgical procedure. Demographic data, perioperative data, and postoperative complications were compared. Statistical analysis included the unpaired t test, Fisher exact, or χ2 test and Gehan-Breslow analysis. RESULTS: Of 4729 esophagectomies, combined anatomic lung resection was performed in 18 patients with discrete pulmonary lesions. Matching yielded 49 patients who underwent esophagectomy only and were statistically similar compared with patients undergoing combined resections. Ivor Lewis esophagectomy and lobectomy were the most frequent procedures. Combined resections did not have a higher overall complication rate than esophagectomy alone; rather, these patients had fewer overall complications (56% vs 84%; P = .02). Specifically, there were no differences in anastomotic leak (17% vs 18%) or pulmonary complications (39% vs 33%) between combined resection and esophagectomy alone. No postoperative mortality were identified, and median overall survival was 4.1 years vs 6.5 years (P = .10). CONCLUSIONS: Patients with synchronous localized lung and esophageal cancer, although rare, should not be biased toward nonsurgical therapy, because the morbidity associated with combined esophagectomy and anatomic lung resection does not differ significantly from esophagectomy alone in this highly selected group of patients.

A More Extensive Lymphadenectomy Enhances Survival After Neoadjuvant Chemoradiotherapy in Locally Advanced Esophageal Adenocarcinoma.

OBJECTIVE: We sought to determine the extent of lymphadenectomy that optimizes staging and survival in patients with locally advanced EAC treated with neoadjuvant chemoradiotherapy followed by esophagectomy. SUMMARY OF BACKGROUND DATA: Several studies have found that a more extensive lymphadenectomy leads to better disease-specific survival in patients treated with surgery alone. Few studies, however, have investigated whether this association exists for patients treated with neoadjuvant chemoradiotherapy. METHODS: We examined our prospective database and identified patients with EAC treated with neoadjuvant chemoradiotherapy followed by esophagectomy between 1995 and 2017. Overall survival (OS) and DFS were estimated using Kaplan-Meier methods, and a multivariable Cox proportional hazards model was used to identify independent predictors of OS and DFS. The relationship between the total number of nodes removed and 5-year OS or DFS was plotted using restricted cubic spline functions. RESULTS: In total, 778 patients met the inclusion criteria. The median number of excised nodes was 21 (interquartile range, 16-27). A lower number of excised lymph nodes was independently associated with worse OS and DFS (OS: hazard ratio, 0.98; confidence interval, 0.97-1.00; P = 0.013; DFS: hazard ratio, 0.99; confidence interval, 0.98-1.00; P = 0.028). Removing 25 to 30 lymph nodes was associated with a 10% risk of missing a positive lymph node. Both OS and DFS improved with up to 20 to 25 lymph nodes removed, regardless of treatment response. CONCLUSIONS: The optimal extent of lymphadenectomy to enhance both staging and survival after chemoradiotherapy, regardless of treatment response, is approximately 25 lymph nodes.

Survival After Trimodality Therapy in Patients With Locally Advanced Esophagogastric Adenocarcinoma: Does Only a Complete Pathologic Response Matter?

OBJECTIVE: To evaluate whether pCR exclusively defines major pathologic response to treatment with improved survival. SUMMARY BACKGROUND DATA: pCR after trimodality therapy for EAC is infrequent but associated with improved prognosis. Yet most clinical trials and correlative studies designate pCR as the primary endpoint. METHODS: We analyzed our prospectively maintained database for patients who underwent trimodality therapy for locally advanced esophageal adeno-carcinoma between 1995 and 2017. Overall survival (OS) was examined by percentage TR in the primary tumor bed and pathologic nodal stage (ypN0) using Kaplan-Meier plots. Optimal thresholds of TR for differentiating patients in terms of OS were investigated with descriptive plots using restricted cubic spline functions; associations were quantified using Cox multivariable analysis. RESULTS: Among 788 patients, median follow-up was 37.5 months (range, 0.4210.6); median OS was 48.3 months (95% CI, 42.2-58.8). Absence of residual nodal disease was independently associated with improved survival ( P < 0.001). Survival curves for 90% to 99% TR and 100% TR were similar, and a change in probability of improved OS was observed at 90% TR. On multivariable analysis, combining 90% to 99% and 100% TR was independently associated with improved OS, compared with 50% to 89% and <50% TR. CONCLUSIONS: ypN0 status is the strongest indicator of major pathologic response to trimodality therapy, in addition to >90% TR in the primary tumor bed. These findings may allow the definition of major pathologic response to be expanded, from pCR to > 90% TR and ypN0. This has meaningful implications for future clinical trials and correlative studies.

A case report of foreign body appendicitis caused by tongue piercing ingestion.

INTRODUCTION: Foreign body ingestion is an uncommon clinical problem in healthy adults. Furthermore, it is even less common for an ingested foreign body to cause any obstructive symptoms within the gastrointestinal tract. PRESENTATION OF CASE: Here, we describe an unusual case of acute appendicitis induced by a tongue piercing that was ingested by a 32-year-old woman with a recent history of endotracheal intubation. Abdominal X-ray revealed metallic foreign bodies in the right lower quadrant. The foreign bodies remained in place on serial X-rays despite bowel preparation and they were not visualized on colonoscopy. Computed tomography (CT) of the abdomen and pelvis confirms the location of the foreign body within the appendix. Laparoscopic appendectomy was performed without complications and the tongue piercing was recovered within the lumen of the resected appendix. DISCUSSION: Foreign body ingestion is a rare cause of appendicitis. Most ingested foreign bodies spontaneously pass through the gastrointestinal tract within a week. However, in rare instances, the foreign body becomes lodged in the appendix, often resulting in appendicitis. CONCLUSION: In patients with appendicitis secondary to foreign body ingestion, we suggest surgical management to reduce the risk of peritonitis, perforation, and abscess formation.

Oligometastases After Curative Esophagectomy Are Not One Size Fits All.

BACKGROUND: More than one-half of patients treated with esophagectomy for esophageal cancer experience recurrence. Oligometastasis, a proposed intermediate state of isolated local or solid organ recurrence that occurs before widespread systemic disease, is a potential target for aggressive local intervention. This study investigated presentation and prognosis among solid organ recurrence sites. METHODS: Patients with isolated solid organ recurrence at the liver, lung, or brain who underwent R0 esophagectomy from 1995 to 2016 were identified. Clinicopathologic characteristics and outcomes were compared among sites of recurrence. Overall survival was quantified using the Kaplan-Meier approach and Cox proportional hazards models. RESULTS: In total, 104 patients were included (site: brain, 37; lung, 27; liver, 40). Eighty percent of liver, 51% of brain, and 44% of lung oligometastases occurred in the first 12 months after esophagectomy. Despite the limited use of aggressive therapy, patients with lung oligometastasis had significantly longer median overall survival (2.41 years; 95% confidence interval [CI], 1.58 to 3.31) than did patients with brain (0.95 years; 95% CI, 0.62 to 1.49) or liver (0.95 years; 95% CI, 0.82 to 1.41) oligometastasis (P < .001). This difference remained after patient and tumor characteristics were adjusted for (brain: hazard ratio, 4.48; 95% CI, 2.24 to 8.99; liver: hazard ratio, 2.94; 95% CI, 1.48 to 5.82). CONCLUSIONS: Presentations and prognoses differ by site of esophageal cancer recurrence. Lung oligometastases are associated with a more indolent course, and patients with these lesions may benefit from more aggressive treatment to improve their more favorable outcomes further. These differences by site of recurrence advocate for moving beyond a standardized palliative approach to all esophageal cancer recurrences.

Primary lung cancer in women after previous breast cancer.

BACKGROUND: Breast cancer is the most common malignancy among women in the USA. Improved survival has resulted in increasing incidence of second primary malignancies, of which lung cancer is the most common. The United States Preventive Services Task Force (USPSTF) guidelines for lung-cancer screening do not include previous malignancy as a high-risk feature requiring evaluation. The aim of this study was to compare women undergoing resection for lung cancer with and without a history of breast cancer and to assess whether there were differences in stage at diagnosis, survival and eligibility for lung-cancer screening between the two groups. METHODS: Women who underwent lung-cancer resection between 2000 and 2017 were identified. Demographic, clinicopathological, treatment and outcomes data were compared between patients with a history of breast cancer (BC-Lung) and patients without a history of breast cancer (P-Lung) before lung cancer. RESULTS: Of 2192 patients included, 331 (15.1 per cent) were in the BC-Lung group. The most common method of lung-cancer diagnosis in the BC-Lung group was breast-cancer surveillance or work-up imaging. Patients in the BC-Lung group had an earlier stage of lung cancer at the time of diagnosis. Five-year overall survival was not statistically significantly different between groups (73.3 per cent for both). Overall, 58.4 per cent of patients (1281 patients) had a history of smoking, and 33.3 per cent (731 patients) met the current criteria for lung-cancer screening. CONCLUSION: Differences in stage at diagnosis of lung cancer and treatment selection were observed between patients with and without a history of breast cancer. Overall, there were no statistically significant differences in genomic or oncogenic pathway alterations between the two groups, which suggests that lung cancer in patients who previously had breast cancer may not be affected at the genomic level by the previous breast cancer. The most important finding of the study was that a high percentage of women with lung cancer, regardless of breast-cancer history, did not meet the current USPSTF criteria for lung-cancer screening.

Variations in postoperative opioid prescribing by day of week and duration of hospital stay.

BACKGROUND: Studies demonstrate wide variation in postoperative opioid prescribing and that patients are at risk of chronic opioid abuse after surgery. The factors that influence prescribing, however, remain obscure. This study investigates whether day of the week or the postoperative day at the time of discharge impacts prescribing patterns. METHODS: We identified patients who underwent commonly performed procedures at our institution from January 2014 through April 2019 and analyzed the relationship between postoperative opioids prescribed (oral morphine milligram equivalents) and both the day of the week and the postoperative day at discharge. RESULTS: In ambulatory operations (n = 13,545), each day progressing from Monday was associated with increased morphine milligram equivalents prescribed on discharge (P = .0080). For inpatient cases (n = 10,838), surgeons prescribed more morphine milligram equivalents at discharge in the latter half of the week and during the weekend (P = .0372). Every additional postoperative day at discharge was associated with a +19.25 morphine milligram equivalent prescribed (P < .0001). CONCLUSION: More opioids were prescribed on discharges later in the week and after prolonged hospital stays perhaps to avoid patients running out of medication. Providers may unintentionally allow such non-clinical factors to influence postoperative opioid prescribing. Increased awareness of these inadvertent biases may help decrease excess prescribing of potentially addicting opioids after an operation.

Defining low-risk lesions in early-stage esophageal adenocarcinoma.

OBJECTIVE: As endoscopic approaches become more widely used to treat early-stage esophageal cancer, reliably identifying patients with less-aggressive tumors is paramount. We sought to identify risk factors for recurrence in patients with completely resected T1 esophageal adenocarcinoma. METHODS: We retrospectively analyzed a single-institutional database for all patients with completely resected pathologic T1 esophageal adenocarcinoma (1996-2016). Risk factors for recurrence were identified using competing-risk regression methods. Risk stratification was performed on the basis of known preoperative clinicopathologic factors; this model's discriminative power for overall survival was evaluated using a Cox proportional hazards model. RESULTS: Of 243 patients, 32 experienced recurrence. At a median follow-up among survivors of 4 years (range, 0.05-19 years), the 5-year cumulative incidence of recurrence was 15%, and median time to recurrence was 2 years (range, 0.26-6.13 years). On univariable analysis, submucosal invasion, N1 disease, poor differentiation, tumor length, lymphovascular invasion, and multicentricity were significantly associated with recurrence. On multivariable analysis, N1 disease (hazard ratio, 2.93; 95% confidence interval, 1.17-7.34; P = .022) and tumor length (hazard ratio, 1.44; 95% confidence interval, 1.12-1.86; P = .004) were independently associated with recurrence. Risk stratification showed that patients without lymphovascular invasion and a with median tumor length of 0.8 cm (range, 0.10-1.70 cm) had a <10% risk of recurrence and improved survival. CONCLUSIONS: Pathologic T1 tumors have a 5-year cumulative incidence of recurrence of 15%. Nodal involvement and tumor length were independent risk factors for recurrence, whereas tumors <2 cm in length without lymphovascular invasion were associated with a low risk of recurrence.

Performance Comparison Between SURPAS and ACS NSQIP Surgical Risk Calculator in Pulmonary Resection.

BACKGROUND: Accurate preoperative risk assessment is critical for informed decision making. The Surgical Risk Preoperative Assessment System (SURPAS) and the National Surgical Quality Improvement Program (NSQIP) Surgical Risk Calculator (SRC) predict risks of common postoperative complications. This study compares observed and predicted outcomes after pulmonary resection between SURPAS and NSQIP SRC. METHODS: Between January 2016 and December 2018, 2514 patients underwent pulmonary resection and were included. We entered the requisite patient demographics, preoperative risk factors, and procedural details into the online NSQIP SRC and SURPAS formulas. Performance of the prediction models was assessed by discrimination and calibration. RESULTS: No statistically significant differences were found between the 2 models in discrimination performance for 30-day mortality, urinary tract infection, readmission, and discharge to a nursing or rehabilitation facility. The ability to discriminate between a patient who will develop a complication and a patient who will not was statistically indistinguishable between NSQIP and SURPAS, except for renal failure. With a C index closer to 1.0, the NSQIP performed significantly better than the SURPAS SRC in discriminating risk of renal failure (C index, 0.798 vs 0.694; P = .003). The calibration curves of predicted and observed risk for each model demonstrate similar performance with a tendency toward overestimation of risk, apart from renal failure. CONCLUSIONS: Overall, SURPAS and NSQIP SRC performed similarly in predicting outcomes for pulmonary resections in this large, single-center validation study with moderate to good discrimination of outcomes. Notably, SURPAS uses a smaller set of input variables to generate the preoperative risk assessment. The addition of thoracic-specific input variables may improve performance.

External Validation of Surgical Risk Preoperative Assessment System in Pulmonary Resection.

BACKGROUND: Accurate preoperative risk assessment is necessary for informed decision making for patients and surgeons. Several preoperative risk calculators are available but few have been examined in the general thoracic surgical patient population. The Surgical Risk Preoperative Assessment System (SURPAS), a risk-assessment tool applicable to a wide spectrum of surgical procedures, was developed to predict the risks of common adverse postoperative outcomes using a parsimonious set of preoperative input variables. We sought to externally validate the performance of SURPAS for postoperative complications in patients undergoing pulmonary resection. METHODS: Between January 2016 and December 2018, 2514 patients underwent pulmonary resection at our center. Using data from our institution's prospectively maintained database, we calculated the predicted risks of 12 categories of postoperative outcomes using the latest version of SURPAS. Performance of SURPAS against observed patient outcomes was assessed by discrimination (concordance index) and calibration (calibration curves). RESULTS: The discrimination ability of SURPAS was moderate across all outcomes (concordance indices, 0.640 to 0.788). Calibration curves indicated good calibration for all outcomes except infectious and cardiac complications, discharge to a location other than home, and mortality (all overestimated by SURPAS). CONCLUSIONS: SURPAS demonstrates outcomes for pulmonary resections with reasonable predictive ability. Discretion should be applied when assessing risk for postoperative infectious and cardiac complications, discharge to a location other than home, and mortality. Although the parsimonious nature of SURPAS is one of its strengths, its performance might be improved by including additional factors known to influence outcomes after pulmonary resection, such as sex and pulmonary function.

Disparities in mortality-to-incidence ratios by race/ethnicity for female breast cancer in New York City, 2002-2016.

BACKGROUND: Racial disparities in New York City (NYC) breast cancer incidence and mortality rates have previously been demonstrated. Disease stage at diagnosis and mortality-to-incidence ratio (MIR) may present better measures of differences in screening and treatment access. Racial/ethnic trends in NYC MIR have not previously been assessed. METHODS: Mammogram rates were compared using the NYC Community Health Survey, 2002-2014. Breast cancer diagnosis, stage, and mortality were from the New York State Cancer Registry, 2000-2016. Primary outcomes were MIR, the ratio of age-adjusted mortality to incidence rates, and stage at diagnosis. Joinpoint regression analysis identified significant trends. RESULTS: Mammogram rates in 2002-2014 among Black and Latina women ages 40 and older (79.9% and 78.4%, respectively) were stable and higher than among White (73.6%) and Asian/Pacific-Islander women (70.4%) (P < .0001). There were 82 733 incident cases of breast cancer and 16 225 deaths in 2000-2016. White women had the highest incidence, however, rates among Black, Latina, and Asian/Pacific Islander women significantly increased. Black and Latina women presented with local disease (Stage I) less frequently (53.2%, 57.6%, respectively) than White (62.5%) and Asian/Pacific-Islander women (63.0%). Black women presented with distant disease (Stage IV) more frequently than all other groups (Black 8.7%, Latina 5.8%, White 6.0%, and Asian 4.2%). Black women had the highest breast cancer mortality rate and MIR (Black 0.25, Latina 0.18, White 0.17, and Asian women 0.11). CONCLUSIONS: More advanced disease at diagnosis coupled with a slower decrease in breast cancer mortality among Black and Latina women may partially explain persistent disparities in MIR especially prominent among Black women. Assessment of racial/ethnic differences in screening quality and access to high-quality treatment may help identify areas for targeted interventions to improve equity in breast cancer outcomes.

Do Socioeconomic Disparities Exist in Postoperative Opioid Prescription and Consumption?

BACKGROUND: Since 1999, >200 000 people in the United States have died from a prescription opioid overdose. Lower socioeconomic status (SES) is one important risk factor. This study investigates socioeconomic disparities in postoperative opioid prescription and consumption. METHODS: September 2018-April 2019, 128 patients were surveyed postoperatively regarding opioid consumption. The neighborhood disadvantage was calculated using area deprivation index (ADI). The top 3 quartiles were "high SES" and the bottom quartile "low SES." RESULTS: The study population included 96 high SES patients, median ADI 6 (2-12.3) and 32 low SES, median ADI 94.5 (81.3-97.3). For both, median Oxycodone 5 mg prescribed was 20 pills. 29.2% of high SES consumed 0 pills, 40.6% consumed 1-9 pills, and 27.1% consumed 10+ pills. 25.0% of low SES consumed 0 pills, 46.9% consumed 1-9 pills, and 18.8% consumed 10+ pills. No significant difference in opioid prescription (P = .792) or consumption (P = .508) between SES groups. DISCUSSION: Patients of all SES are prescribed and consumed opioids in similar patterns with no significant difference in postoperative pain following ambulatory surgery.
