Extent of Resection and Long-Term Outcomes for Appendiceal Adenocarcinoma: a SEER Database Analysis of Mucinous and non-Mucinous Histologies.

BACKGROUND: Mucinous appendiceal adenocarcinomas (MAA) and non-mucinous appendiceal adenocarcinomas (NMAA) demonstrate differences in rates and patterns of recurrence, which may inform the appropriate extent of surgical resection (i.e., appendectomy versus colectomy). The impact of extent of resection on disease-specific survival (DSS) for each histologic subtype was assessed. PATIENTS AND METHODS: Patients with resected, non-metastatic MAA and NMAA were identified in the Surveillance, Epidemiology, and End Results database (2000-2020). Multivariable models were created to examine predictors of colectomy for each histologic subtype. DSS was calculated using Kaplan-Meier estimates and examined using Cox proportional hazards modeling. RESULTS: Among 4674 patients (MAA: n = 1990, 42.6%; NMAA: n = 2684, 57.4%), the majority (67.8%) underwent colectomy. Among colectomy patients, the rate of nodal positivity increased with higher T-stage (MAA: T1: 4.6%, T2: 4.0%, T3: 17.1%, T4: 21.6%, p < 0.001; NMAA: T1: 6.8%, T2: 11.4%, T3: 25.6%, T4: 43.8%, p < 0.001) and higher tumor grade (MAA: well differentiated: 7.7%, moderately differentiated: 19.2%, and poorly differentiated: 31.3%; NMAA: well differentiated: 9.0%, moderately differentiated: 20.5%, and 44.4%; p < 0.001). Nodal positivity was more frequently observed in NMAA (27.6% versus 16.4%, p < 0.001). Utilization of colectomy was associated with improved DSS for NMAA patients with T2 (log rank p = 0.095) and T3 (log rank p = 0.018) tumors as well as moderately differentiated histology (log rank p = 0.006). Utilization of colectomy was not associated with improved DSS for MAA patients, which was confirmed in a multivariable model for T-stage, grade, and use of adjuvant chemotherapy [hazard ratio (HR) 1.00, 95% confidence interval (CI) 0.81-1.22]. CONCLUSIONS: Colectomy was associated with improved DSS for patients with NMAA but not MAA. Colectomy for MAA may not be required.

The order of surgery and chemotherapy matters: Multimodality therapy and stage-specific differences in survival in gastric cancer.

BACKGROUND AND OBJECTIVES: Multimodality treatment improves survival for gastric cancer (GC). However, the effect of treatment sequence by stage remains unclear. We aim to compare outcomes between patients receiving neoadjuvant(neoadj) and adjuvant chemotherapy (adj). METHODS: Nonmetastatic GC patients with clinical stage ≥ T2N0 who underwent both resection and neoadj or adj were identified using the National Cancer Database (2005-2014). Multivariable Cox regression analyses were performed on propensity score-matched (PSM) cohorts stratified by stage to compare overall survival (OS). RESULTS: We identified 11 984 patients; 55% stage I (SI), 76% stage II (SII) and 57% stage III (SIII) received neoadj. Unadjusted analysis showed worse survival among SI neoadj patients (hazard ratio [HR] 1.195, confidence interval [CI] 1.04-1.38) and improved survival for SII (HR 0.93 CI 0.87-0.998) and SIII (HR 0.75, CI 0.68-0.84). After PSM, SI patients with neoadj had worse OS with increased risk of death compared to Adj (HR 1.186, CI 1.004-1.402). SII patients had no difference in OS (HR 0.98, CI 0.91-1.07) and SIII patients had improved OS (HR 0.78, CI 0.69-0.90). CONCLUSIONS: In patients who received surgery and chemotherapy, the benefit of neoadj was limited to SIII with worse survival for SI. A clinical trial to examine the optimal sequence of chemotherapy is warranted.

Surgery Refusal Among Black and Hispanic Women with Non-Metastatic Breast Cancer.

BACKGROUND: Studies have shown a lower receipt of treatment among minority women with non-metastatic breast cancer. Those who refuse surgery have increased disease-specific mortality, contributing to disproportionately higher breast cancer mortality in non-Hispanic black (NHB) and Hispanic women. This study aimed to assess surgery refusal in these groups, identify factors associated with surgery refusal, and characterize the association between surgery refusal and survival. METHODS: Surveillance, Epidemiology, and End Results (SEER) Program data from 2005 to 2015 for NHB and Hispanic women with a diagnosis of non-metastatic breast cancer (n = 113,987) was divided into data of those who underwent surgery and data of those who refused surgery. Sociodemographic and tumor clinical/pathologic differences were analyzed by multivariate logistic regression of predictors of surgery refusal and Cox-proportional hazard model of disease-specific mortality. RESULTS: Of 799 patients who refused surgery, 562 were NHB and 237 were Hispanic. The percentage of patients refusing surgery increased from 0.6% in 2005 to 0.9% in 2015. The women who refused surgery were more likely to be older than 81 years, less likely to be married, and more likely to be uninsured or have Medicaid. The refusers presented with more advanced disease and more frequent estrogen receptor-positivity (ER+) and progesterone receptor-positivity (PR+) subtype on histology. Breast cancer-specific mortality increased significantly with surgery omission. Surgery refusal was independently associated with NHB race. CONCLUSION: Surgery refusal among NHB and Hispanic women with potentially curable non-metastatic breast cancer is rising, especially among NHB women, women older than 60 years, single women, and women with a later stage of disease at diagnosis. Additional studies are needed to analyze qualitative data in these populations and their underlying health beliefs, communication needs, and possible use of alternative medicine.

Access Denied: Inequities in Clinical Trial Enrollment for Pancreatic Cancer.

BACKGROUND: The influence of social determinants of health (SDH) on participation in clinical trials for pancreatic cancer is not well understood. In this study, we describe trends and identify disparities in pancreatic cancer clinical trial enrollment. PATIENTS AND METHODS: This is a retrospective study of stage I-IV pancreatic cancer patients in the 2004-2016 National Cancer Database. Cohort was stratified into those enrolled in clinical trials during first course of treatment versus not enrolled. Bivariate analysis and logistic regression were used to understand the relationship between SDH and clinical trial participation. RESULTS: A total of 1127 patients (0.4%) enrolled in clinical trials versus 301,340 (99.6%) did not enroll. Enrollment increased over the study period (p < 0.001), but not for Black patients or patients on Medicaid. The majority enrolled had metastatic disease (65.8%). On multivariate analysis, in addition to year of diagnosis (p < 0.001), stage (p < 0.001), and Charlson score (p < 0.001), increasing age [odds ratio (OR) 0.96, 95% confidence interval (CI) 0.96-0.97], non-white race (OR 0.54, CI 0.44-0.66), living in the South (OR 0.42, CI 0.35-0.51), and Medicaid, lack of insurance, or unknown insurance (0.41, CI 0.31-0.53) were predictors of lack of participation. Conversely, treatment at an academic center (OR 6.36, CI 5.4-7.4) and higher neighborhood education predicted enrollment (OR 2.0, CI 1.55-2.67 for < 7% with no high school degree versus > 21%). DISCUSSION: Age, race, insurance, and geography are barriers to clinical trial enrollment for pancreatic cancer patients. While overall enrollment increased, Black patients and patients on Medicaid remain underrepresented. After adjusting for cancer-specific factors, SDH are still associated with clinical trial enrollment, suggesting need for targeted interventions.

All Politics Are Local: A Single Institution Investigation of the Educational Impact of Residents and Fellows Working Together.

BACKGROUND: Most general surgery residents pursue fellowship; there is limited understanding of the impact residents and fellows have on each other's education. The goal of this exploratory survey was to identify these impacts. MATERIALS AND METHODS: Surgical residents and fellows at a single academic institution were surveyed regarding areas (OR assignments, the educational focus of the team, roles and responsibilities on the team, interpersonal communication, call, "other") hypothesized to be impacted by other learners. Impact was defined as "something that persistently affects the clinical learning environment and a trainee's education or ability to perform their job". Narrative responses were reviewed until dominant themes were identified. RESULTS: Twenty-three residents (23/45, 51%) and 12 fellows (12/21, 57%) responded. Responses were well distributed among resident year (PGY-1:17% [4/23], PGY-2, 35% [8/23], PGY-3 26% [6/23], PGY-4 9% [2/23%], PGY-5 13% [3/23]). Most residents reported OR assignment (14/23, 61%) as the area of primary impact, fellows broadly reported organizational categories (Roles and responsibilities 33%, educational focus 16%, interpersonal communication 16%). Senior residents reported missing out on operations to fellows while junior residents reported positive impacts of operating directly with fellows. Residents of all levels reported that fellows positively contributed to their education. Fellows, senior residents, and junior residents reported positive experiences when residents and fellows operated together as primary surgeon and assistant. CONCLUSIONS: Residents and fellows impact one another's education both positively and negatively. Case allocation concerns senior residents, operating together may alleviate this, providing a positive experience for all trainees. Defining a unique educational role for fellows and delineating team expectations may maximize the positive impacts in this relationship.

Hormone receptor-positive breast cancer and black race: does sex matter?

PURPOSE: Black breast cancer patients have worse clinical outcomes than their White counterparts. There are few studies comparing clinical outcomes between Black male breast cancer (MBC) and female breast cancer (FBC) patients. The objective of this study is to examine differences in presentation, treatment, and mortality between Black MBC and FBC. METHODS: The National Cancer Database was queried for all Black MBC and FBC patients, ages 18-90, with hormone receptor-positive breast cancer diagnosed between 2010 and 2016. Hormone receptor positivity was defined as estrogen receptor-positive, progesterone-positive and HER 2-negative cancer. Sociodemographic and clinical variables were compared between MBC and FBC patients on bivariable analysis. After propensity score matching, overall survival was evaluated using the log-rank test and Cox proportional hazards. RESULTS: Compared to FBC patients, MBC patients had higher rates of metastatic disease (stage 4, MBC 4.4% vs. FBC 2.6%, p < 0.001), larger tumors (tumor size < 2 cm, MBC 32.1 vs. FBC 49.1%, p < 0.001) and a higher percentage of poorly differentiated tumors (grade 3, MBC 28.5% vs. FBC 21.4%, p < 0.001). MBC patients had lower rates of hormone therapy (MBC 66.4% vs. FBC 80.7%, p < 0.001) and neoadjuvant chemotherapy (MBC 5.8% vs. FBC 7.5%, p = 0.05) than FBC. On propensity score matched analysis, Black MBC patients had a higher overall mortality (p25 of 60 months vs. 74 months) compared to FBC patients (p = 0.0260). CONCLUSION: Among hormone receptor-positive Black MBC and FBC patients, there are sex-based disparities in stage, hormone therapy use and overall survival.

Racial Differences in Response to Neoadjuvant Chemotherapy: Impact on Breast and Axillary Surgical Management.

BACKGROUND: Neoadjuvant chemotherapy (NAC), an increasingly used method for breast cancer patients, has the potential to downstage patient tumors and thereby have an impact on surgical options for treatment of the breast and axilla. Previous studies have identified racial disparities in tumor heterogeneity, nodal recurrence, and NAC completion. This report compares the effects of NAC response among non-Hispanic white women and black women in relation to surgical treatment of the breast and axilla. METHODS: A retrospective review of 85,303 women with stages 1 to 3 breast cancer in the National Cancer Database who received NAC between 1 January 2010 and 31 December 2016 was conducted. Differences in sociodemographic and clinical variables between black patients and white patients with breast cancer were tested. RESULTS: The study identified 68,880 non-Hispanic white and 16,423 non-Hispanic black women who received NAC. The average age at diagnosis was 54.8 years for the white women versus 52.5 years for the black women. A higher proportion of black women had stage 3 disease, more poorly differentiated tumors, and triple-negative subtype. The black women had lower rates of complete pathologic response, more breast-conservation surgery, and higher rates of axillary lymph node dissection, but fewer sentinel lymph node biopsies. Axillary management for the women who were downstaged showed more use of axillary lymph node dissection for black women compared with sentinel lymph node biopsy. CONCLUSIONS: The black patients were younger at diagnosis, had more advanced disease, and were more likely to have breast-conservation surgery. De-escalating axillary surgery is being adopted increasingly but used disproportionately for white women.

Efficiency of Increasing Prospective Resident Entrustment in the Operating Room.

BACKGROUND: Prospective resident entrustment (i.e., trust an attending surgeon intends to give to a resident in the near future) in the operating room (OR) closely associates with granted future autonomy. However, the process of determining resident entrustment takes time and effort. Thus, this study aimed to assess the efficiency of granting incremental resident entrustment for upcoming surgical cases. METHODS: We analyzed prospective resident entrustment of 6 chief residents in 76 cases of laparoscopic cholecystectomy, laparoscopic colectomy, ventral hernia, and inguinal hernia scored by attending surgeon, resident, and a surgeon observer. Matched direct costs and operative time were extracted from hospital billing. We assessed the efficiency of granting incremental prospective resident entrustment with direct cost per minute incurred in the evaluated case. Effect size was computed to assess the differences between groups. RESULTS: Sixty-three cases (82.9%) were matched; 47.6% (30/63) of matched cases received prospective resident entrustment score ≥ 4. The direct cost per minute increased in three procedures (laparoscopic cholecystectomy, laparoscopic colectomy, and ventral hernia) with increased intention of granting incremental resident entrustment. Inguinal hernia was the only procedure in which chiefs were entrusted with future independence while the direct cost per minute decreased. CONCLUSIONS: Our findings demonstrate more time and effort are required (except for inguinal hernia) for residents to be entrusted with increased independence in the future. Faculty and resident development programs are recommended to improve the efficiency of the process of granting incremental operative entrustment to optimize resident training quality and cost of care delivery.

Education Morbidity and Mortality: Reviving Intraoperative Teaching and Learning.

BACKGROUND: Using the platform of morbidity and mortality conference, we developed and executed a combined faculty-resident intervention called "Education M&M" to discuss challenges faced by both parties in the operating room (OR), identify realistic solutions, and implement action plans. This study aimed to investigate the impact of this intervention on resident OR training. MATERIALS AND METHODS: Two resident case presentations were followed by audience discussion and recommendations regarding actionable solutions aimed at improving resident OR training from an expert faculty panel. Postintervention surveys were completed by participants immediately and 2 mo later to assess perceived short and long-term impact on OR teaching and/or learning and the execution of two recommended solutions. Descriptive statistical analysis was applied. RESULTS: Immediate post-intervention surveys (n = 44) indicated that 81.8% of participants enjoyed the M&M "a lot"; 90.1% said they would use some or a lot of the ideas presented. Awareness of OR teaching/learning challenges before and after the M&M improved from 3.0 to 3.7 (P = 0.00001) for faculty and 3.0 to 3.9 for trainees (P = 0.00004). Understanding of OR teaching and/or learning approaches improved from 3.1 to 3.7 for faculty (P = 0.00004) and 2.7 to 3.9 for trainees (P = 0.00001). In 2-mo post-intervention surveys, most residents had experienced two recommended solutions (71% and 88%) in the OR, but self-reported changes to faculty behavior did not reach statistical significance. CONCLUSIONS: A department-wide education M&M could be an effective approach to enhance mutual communication between faculty members and residents around OR teaching/learning by identifying program-specific challenges and potential actionable solutions.

Racial disparities in low-value surgical care and time to surgery in high-volume hospitals.

BACKGROUND: The objective of this study is to examine racial differences in receipt of low-value surgical care and time to surgery (TTS) among women receiving treatment at high-volume hospitals. METHODS: Stage I-III non-Hispanic Black (NHB) and Non-Hispanic White (NHW) breast cancer patients were identified in the National Cancer Database. Low-value care included (1) sentinel lymph node biopsy (SLNB) among T1N0 patients age ≥70 with hormone receptor-positive cancers, (2) axillary lymph node dissection (ALND) in patients meeting ACOSOG Z0011 criteria, and (3) contralateral prophylactic mastectomy (CPM) with unilateral cancer. TTS was days from biopsy to surgery. Bivariate and logistic regression analyses were used to compare the groups. RESULTS: Compared to NHWs, NHBs had lower rates of SLNB among women age ≥70 with small hormone-positive cancers (NHB 58.5% vs. NHW 62.2% p < .001) and CPM (NHB 26.3% vs. NHW 36%; p < .001). ALND rates for patients meeting ACOSOG Z0011 criteria were similar between both groups (p = .13). The odds of surgery >60 days were higher among NHBs (odds ratio, 1.77; 95% confidence interval, 1.64-1.91; NHW ref). CONCLUSIONS: NHBs treated at high-volume hospitals have higher rates of surgical delay but are less likely to undergo low-value surgical procedures compared to NHW women.

Mitigation of the Robotic Pancreaticoduodenectomy Learning Curve through comprehensive training.

BACKGROUND: There is an associated lag in achieving competency for robotic pancreaticoduodenectomy (PD), resulting in a learning curve. We hypothesize that the reported learning curve can be mitigated through a comprehensive graduated training protocol. METHODS: All patients (n = 237) who underwent an open (n = 197, 83.1%) or robotic (n = 40, 16.9%) PD between 2015-2019 were identified at The Ohio State University. The learning curve for operative time and surgical failure (defined as conversion to open, blood transfusion, or Clavien-Dindo complication grade ≥3) was analyzed using a risk adjusted cumulative summation technique. RESULTS: After 10 cases, operative time plateaued to a mean of 468.3 ± 96.3 minutes for robotic PD versus a mean of 332.5 ± 103.9 minutes for open PD (P < 0.001). There was no further apparent learning curve over time relative to rates of operative time or surgical failure. After propensity score-matching, patients undergoing robotic PD had a similar incidence of major complications, grade B/C postoperative pancreatic fistula, and delayed gastric emptying versus patients undergoing open PD (all P > 0.05). CONCLUSION: Completion of a comprehensive procedure-specific robotic training protocol for PD mitigated the learning curve for this operative approach by shifting the curve into the training/simulation phase rather than the live operating phase. These data hold important implications for the future training and accreditation of surgeons embarking on robotic PD.

Overcoming a Hostile Work and Learning Environment in Academic Surgery-Tools for Change at Every Level.

Mistreatment has been documented as a negative factor in the learning environment for the past 30 y but little progress has been made to determine an effective way to significantly improve these interactions. Faculty may also be victims of a hostile work environment as well, although frequency has not been well-measured or reported. In fact, it may be difficult to identify and address mistreatment and hostility in the work place within the commonly established surgical culture. Thus, efforts to define, identify, and address workplace mistreatment or hostility are crucial to the success of the academic surgical environment. This article summarizes presentations and panel discussion that took place at the 2019 Academic Surgical Congress organized by the Association for Academic Surgery and the Society of University Surgeons. Definitions of mistreatment and hostility were provided, as well as information regarding occurrence. Tools for addressing mistreatment in the work environment and tips for creating a positive environment were presented and discussed.

Braden scale for pressure ulcer risk predicts rehabilitation placement after pancreatic resection.

BACKGROUND: Patients undergoing pancreatic resection frequently require rehabilitation facilities after hospital discharge. We evaluated the predictive role of validated markers of frailty on rehabilitation facility placement to identify patients who may require this service. METHODS: Single-center retrospective cohort study of patients who underwent pancreatic resection from 2010 to 2015. 90-day morbidity and mortality were calculated. Postoperative validated markers of frailty (Activities of Daily Living scale, Braden scale [assesses pressure ulcer risk, lower scores = higher risk] and Morse fall scale) were evaluated via multivariate regression to identify predictors of discharge to rehabilitation facility. RESULTS: 470 patients with complete data were included. Mean age was 62 and 49.2% were male. Postoperative median length of stay (LOS) was 8 (IQR 7-10). 92 (19.66%) patients were discharged to rehabilitation facilities and 138 (29.49%) patients were readmitted within 90 days. On multivariate analysis, age, sex, LOS > 8 days, inpatient Comprehensive Complication Index (CCI) and initial Braden scale were predictive of rehabilitation placement. CONCLUSION: A marker of frailty routinely collected daily by nursing staff, the Braden scale, is available to help surgeons predict the need for postoperative rehabilitation placement after pancreatic resection. Engaging discharge planning services for at-risk patients may help prevent delayed hospital discharge and should be further evaluated.

Stereotactic body radiotherapy for unresected pancreatic cancer: A nationwide review.

BACKGROUND: The role of conventional radiotherapy in the management of pancreatic cancer has yet to be elucidated. Over the past decade, stereotactic body radiotherapy (SBRT) has emerged as a novel therapeutic option in pancreatic cancer care. This study evaluated the survival impact of SBRT on patients with unresected pancreatic cancer. METHODS: The National Cancer Data Base was queried for unresected patients who received chemotherapy for nonmetastatic pancreatic adenocarcinoma between 2004 and 2012. Four treatment groups were identified: chemotherapy alone, chemotherapy combined with external-beam radiotherapy (EBRT), chemotherapy combined with intensity-modulated radiotherapy (IMRT), and chemotherapy combined with SBRT. Propensity score models predicting the odds of receiving SBRT were created to control for potential selection bias, and patients were matched by propensity scores. The survival analysis was performed with the Kaplan-Meier method. RESULTS: A total of 14,331 patients met the inclusion criteria. Chemotherapy alone was delivered to 5464 patients (38.1%); 6418 (44.8%), 322 (2.3%), and 2127 (14.8%) received chemotherapy along with EBRT, IMRT, and SBRT, respectively. The unadjusted median survival before matching was 9.9, 10.9, 12.0, and 13.9 months for patients treated with chemotherapy, EBRT, IMRT, and SBRT, respectively. In separate matched analyses, SBRT remained superior to chemotherapy alone (log-rank P < .0001) and EBRT (log-rank P = .0180). After matching, survival did not differ between patients receiving IMRT and patients receiving SBRT (log-rank P = .0492). CONCLUSIONS: SBRT is associated with a significantly better outcome than chemotherapy alone or in conjunction with traditional EBRT. These results support the idea that SBRT is a promising treatment approach for patients with unresected pancreatic cancer. Cancer 2017;123:4158-4167. © 2017 American Cancer Society.

Nationwide Evaluation of Patient Selection for Minimally Invasive Distal Pancreatectomy Using American College of Surgeons' National Quality Improvement Program.

OBJECTIVE: To assess current nationwide case selection factors for minimally invasive distal pancreatectomy (MIDP) and identify actual risk factors for adverse outcomes compared with open distal pancreatectomy (ODP). BACKGROUND: Patient selection criteria that predict outcomes after MIDP remain unknown. As a result, widespread adoption of this surgical technique may have been delayed and its potential benefits possibly under-exploited. METHODS: Retrospective cohort study of elective ODP and MIDP performed at 106 centers in 2014, using the pancreas-targeted American College of Surgeons' National Quality Improvement Program (ACS-NSQIP) database. Exclusion criteria were neoadjuvant treatment or pancreatitis as only diagnosis. Primary outcome includes a composite major morbidity metric, reflecting adverse events including mortality and reoperation. Multivariable modeling was used to detect current selection factors and to identify actual risk factors of composite major morbidity. RESULTS: A total of 928 patients underwent ODP (n = 472) or MIDP (n = 456) using a laparoscopic or robot-assisted approach, 24% for pancreatic ductal adenocarcinoma (PDAC). Current selection factors for MIDP were benign disease (odds ratio: OR: 1.56, CI: 1.10-2.21) and body mass index (BMI) 30-40 (OR: 1.41, CI: 1.04-1.91). Current selection factors for ODP were PDAC (OR: 0.45, CI: 0.31-0.64), benign tumor size >5 centimeters (OR: 0.40, CI: 0.23-0.67), and multivisceral procedures (OR: 0.39, CI: 0.26-0.59). Risk factors for composite major morbidity did not differ between ODP and MIDP. A trend was observed between MIDP and a lower risk of composite major morbidity compared with ODP (OR: 0.43, CI: 0.17-1.07). CONCLUSIONS: Current selection factors for ODP or MIDP (benign disease, tumor size, and BMI) do not mitigate the risk of major morbidity. We found no evidence that MIDP should be avoided based on tumor etiology or size, BMI, or patient physical status.

Massachusetts Healthcare Reform and Trends in Emergent Colon Resection.

BACKGROUND: Insurance impacts access to therapeutic options, yet little is known about how healthcare reform might change the pattern of surgical admissions. OBJECTIVE: We compared rates of emergent admissions and outcomes after colectomy before and after reform in Massachusetts with a nationwide control group. DESIGN: This study is a retrospective cohort analysis in a natural experiment. Prereform was defined as hospital discharge from 2002 through the second quarter of 2006 and postreform from the third quarter of 2006 through 2012. Categorical variables were compared by χ. Piecewise functions were used to test the effect of healthcare reform on the rate of emergent surgeries. SETTINGS: The study included acute care hospitals in the Massachusetts Healthcare Cost and Utilization Project State Inpatient Database (2002-2012) and the Nationwide Inpatient Sample (2002-2011). PATIENTS: Patients aged 18 to 64 years with public or no insurance who underwent inpatient colectomy (via International Classification of Diseases, Ninth Revision, Clinical Modification procedural code) were included and patients with Medicare were excluded. INTERVENTION: Massachusetts health care reform was the study intervention. MAIN OUTCOME MEASURES: We measured the rate of emergent colectomy, complications, and mortality. RESULTS: The unadjusted rate of emergent colectomies was lower in Massachusetts after reform but did not change nationally over the same time period. For emergent surgeries in Massachusetts, a piecewise model with an inflection point (peak) in the third quarter of 2006, coinciding with implementation of healthcare reform in Massachusetts, had a lower mean squared error than a linear model. In comparison, the national rate of emergent surgeries demonstrated no change in pattern. Postreform, length of stay decreased by 1 day in Massachusetts; however, there were no significant improvements in other outcomes. LIMITATIONS: The study was limited by its retrospective design and unadjusted analysis. CONCLUSIONS: There was a unique and sustained decline in the rate of emergent colon resection among publically insured and uninsured patients after 2006 in Massachusetts, in contradistinction to the national pattern, suggesting improved access to care associated with health insurance expansion. The reasons for lack of improvement in outcomes are multifactorial.

Hemorrhage after pancreaticoduodenectomy: does timing matter?

BACKGROUND: Hemorrhage after pancreaticoduodenectomy is a potentially fatal complication. We retrospectively reviewed state-wide data to evaluate incidence, type of hemorrhage, treatment modalities, and outcomes. METHODS: Healthcare Cost and Utilization Project's Florida State Inpatient Database was queried 2007-2011 for patients undergoing pancreaticoduodenectomy. Characteristics and outcomes were compared by χ2. Multivariate logistic regression model was generated for risk of hemorrhage during index visit. RESULTS: Of 2548 patients, 217 (8.5%) developed post-operative hemorrhage during their index visit with 139 (64.0%) requiring angiographic, endoscopic, or operative intervention. Overall mortality during index visit was 5.7% (146) - significantly higher in those patients who had post-operative hemorrhage (24.9%) vs not (4.0%) (p < 0.0001). Mortality was significantly higher when post-operative hemorrhage occurred during the second (POD 8-14) vs first (POD 0-7) week at 15/28 vs 16/74, respectively (p = 0.007). On multivariate analysis, male sex (OR 1.56, p = 0.003), vascular resection (OR 1.88, p = 0.017), very low hospital volume (≤7 PD/year; OR 1.62, p = 0.016), and post-operative intra-abdominal/wound infection (OR 2.31, p < 0.0001) were independent predictors for risk of hemorrhage during index visit. CONCLUSIONS: Hemorrhage following pancreaticoduodenectomy remains common, resulting in significantly increased mortality. Hemorrhage during the second post-operative week carries approximately double the mortality of early bleeding, suggesting different etiologies requiring differing treatment approaches.

Early surgical bypass versus endoscopic stent placement in pancreatic cancer.

INTRODUCTION: The optimal treatment for biliary obstruction in pancreatic cancer remains controversial between surgical bypass and endoscopic stenting. METHODS: Retrospective analysis of unresected pancreatic cancer patients in the Healthcare Cost and Utilization Project Florida State Inpatient and Ambulatory Surgery databases (2007-2011). Propensity score matching by procedure. Primary outcome was reintervention, and secondary outcomes were readmission, overall length of stay (LOS), discharge home, death and cost. Multivariate analyses performed by logistic regression. RESULTS: In a matched cohort of 622, 20.3% (63) of endoscopic and 4.5% (14) of surgical patients underwent reintervention (p < 0.0001) and 56.0% (174) vs. 60.1% (187) were readmitted (p = 0.2909). Endoscopic patients had lower median LOS (10 vs. 19 days, p < 0.0001) and cost ($21,648 vs. $38,106, p < 0.0001) as well as increased discharge home (p = 0.0029). No difference in mortality on index admission. On multivariate analysis, initial procedure not predictive of readmission (p = 0.1406), but early surgical bypass associated with lower odds of reintervention (OR = 0.233, 95% CI 0.119, 0.434). DISCUSSION: Among propensity score-matched patients receiving bypass vs. stenting, readmission and mortality rates are similar. However, candidates for both techniques may experience fewer subsequent procedures if offered early biliary bypass with the caveats of decreased discharge home and increased cost/LOS.
