RESUMO

BACKGROUND: The implementation of acuity circles (AC) in 2020 and the COVID-19 pandemic increased the use of local surgeons to recover livers for transplant; however, the impact on liver transplant (LT) outcomes is unknown. METHODS: Deceased donor adult LT recipients from the UNOS database were identified.  Recipients were grouped by donor surgeon: local versus primary recovery.  Patient and graft survival as well as trends in local recovery in the 2 years pre-AC and post-AC were assessed. RESULTS: The utilization of local recovery in LT increased from 22.3% to 37.9% post-AC (p < 0.01).  LTs with local recovery had longer cold ischemia times (6.5 h [5.4-7.8] vs. 5.3 h [4.4-6.5], p < 0.01) and traveled further (210 miles [89-373] vs. 73 miles [11-196], p < 0.01) than those using primary recovery. Multivariate analyses revealed no differences in patient or graft survival between local and primary recovery, and between OPO and local surgeon. There was no difference in survival when comparing simultaneous liver-kidney, donation after circulatory death, MELD ≥ 30, or redo-LT by recovery team.  Recovery and utilization rates were also noted to be higher post-AC (51.4% vs. 48.6% pre-AC, p < 0.01) as well as when OPO surgeons recovered the allografts (72.5% vs. 66.0%, p < 0.01). CONCLUSION: Nearly 40% of LTs are performed using local recovery, and utilization rates and trends continue to change with changing organ-sharing paradigms such as AC.  This practice appears safe with outcomes similar to recovery by the primary team in appropriately selected recipients and may lead to increased access and the ability to transplant more livers.

RESUMO

A biodegradable hybrid polymer patch was invented at the University of Cincinnati to cover gaps on the skin over the spinal column of a growing fetus, characterized by the medical condition spina bifida. The inserted patch faces amniotic fluid (AF) on one side and cerebrospinal fluid on the other side. The goal is to provide a profile of the roughness of a patch over time at 0, 4, 8, 12, and 16 weeks with a 95% confidence band. The patch is soaked in a test tube filled with either amniotic fluid (AF) or phosphate-buffered saline (PBS) in the lab. If roughness is measured at any time point for a patch, the patch is destroyed. Thus, it is impossible to measure roughness at all weeks of interest for any patch. It is important to assess the roughness of a patch because the rougher the patch is, the faster the skin grows under the patch. We use a model-based approach with Monte Carlo simulations to estimate the profile over time with a 95% confidence band. The roughness profiles are similar with both liquids. The profile can be used as a template for future experiments on the composition of patches.

RESUMO

BACKGROUND: Feeding jejunostomy (JT) tubes are often utilized as an adjunct to optimize nutrition for successful esophagectomy; however, their utility has come into question. The aim of this study was to evaluate utilization and outcomes associated with JTs in a nationwide cohort of patients undergoing esophagectomy. METHODS: The NSQIP database was queried for patients who underwent elective esophagectomy. JT utilization was assessed between 2010 and 2019. Post-operative outcomes were compared between those with and without a JT on patients with esophagectomy-specific outcomes (2016-2019), with results validated using a propensity score-matched (PSM) analysis based on key clinicopathologic factors, including tumor stage. RESULTS: Of the 10,117 patients who underwent elective esophagectomy over the past decade, 53.0% had a JT placed concurrently and 47.0% did not. Utilization of JTs decreased over time, accounting for 60.0% of cases in 2010 compared to 41.7% in 2019 (m = - 2.14 95%CI: [- 1.49]-[- 2.80], p < 0.01). Patients who underwent JT had more composite wound complications (17.0% vs. 14.1%, p = 0.02) and a higher rate of all-cause morbidity (40.4% vs. 35.5%, p = 0.01). Following PSM, 1007 pairs were identified. Analysis of perioperative outcomes demonstrated a higher rate of superficial skin infections (6.1% vs. 3.5%, p = 0.01) in the JT group. However, length of stay, reoperation, readmission, anastomotic leak, composite wound complications, all-cause morbidity, and mortality rates were similar between groups. CONCLUSIONS: Among patients undergoing elective esophagectomy, feeding jejunostomy tubes were utilized less frequently over the past decade. Similar perioperative outcomes among matched patients support the safety of esophagectomy without an adjunct feeding jejunostomy tube.

RESUMO

OBJECTIVE: Low-dose computed tomography has been proven to reduce mortality, yet utilization remains low. The purpose of this study is to identify factors that impact the utilization of lung cancer screening. METHODS: We performed a retrospective review of our institution's primary care network from November 2012 to June 2022 to identify patients who were eligible for lung cancer screening. Eligible patients were 55 to 80 years of age and current or former smokers with at least a 30 pack-year history. Analyses were performed on the screened populations and patients who met eligibility criteria but were not screened. RESULTS: A total of 35,279 patients in our primary care network were current/former smokers aged 55 to 80 years. A total of 6731 patients (19%) had a 30 pack-year or more cigarette history, and 11,602 patients (33%) had an unknown pack-year history. A total of 1218 patients received low-dose computed tomography. The utilization rate of low-dose computed tomography was 18%. The utilization rate was significantly lower (9%) if patients with unknown pack-year history were included (P < .001). The utilization rates between primary care clinic locations were significantly different (range, 18% vs 41%, P < .05). Utilization of low-dose computed tomography on multivariate analysis was associated with Black race, former smoker, chronic obstructive pulmonary disease, bronchitis, family history of lung cancer, and number of primary care visits (all P < .05). CONCLUSIONS: Lung cancer screening utilization rates are low and vary significantly on the basis of patient comorbidities, family history of lung cancer, primary care clinic location, and accurate documentation of pack-year cigarette history. The development of programs to address patient, provider, and hospital-level factors is needed to ensure appropriate lung cancer screening.

RESUMO

BACKGROUND: Enhanced recovery after surgery (ERAS) has been associated with improved perioperative outcomes after thoracic surgery; however, the impact on long-term opioid use remains unknown. The aim of our study was to evaluate the effects of ERAS on long-term opioid use. METHODS: Patients who underwent pulmonary resection were identified from a prospectively maintained database and linked to the regional prescription drug monitoring program. Outcomes were compared between pre-ERAS (February 2016 to November 2018) and ERAS (December 2018 to June 2020) cohorts. Our ERAS protocol included regional anesthetic, multimodal pain control, and protocolized rehabilitation. RESULTS: We analyzed 240 pulmonary resections, 64.6% (n = 155) in the pre-ERAS era and 35.4% (n = 85) in the ERAS era. Baseline characteristics were similar; however, more patients in the ERAS cohort underwent minimally invasive surgery (67.7% vs 87.9%; P = .002). Median length of stay was reduced (5 days vs 4 days; P = .03) upon implementation of ERAS, with no change in perioperative complications or readmission rate. On multivariate analysis, ERAS was associated with decreased total inpatient morphine milligram equivalent and discharge morphine milligram equivalent. However, both long-term opioid use up to 1 year postoperatively and new persistent opioid use remained similar despite implementation of ERAS. On multivariate analysis, implementation of ERAS was not associated with a reduction in opioid use 14 to 90 days postoperatively or persistent opioid use 90 to 180 days postoperatively. CONCLUSIONS: Despite short-term opioid reduction, long-term opioid use persisted after implementation of ERAS. Additional strategies to monitor for and avoid opioid dependence are urgently needed to prevent chronic opioid use after pulmonary resection.

RESUMO

BACKGROUND: Microsatellite instability (MSI) has been associated with improved overall survival (OS) in locoregional colorectal cancer; however, the effects on colorectal liver metastases (CRLM) have not been studied. METHODS: The National Cancer Database (NCDB) was queried for patients with CRLM that underwent metastasectomy. Patients with microsatellite stable tumors (MSS) (n = 2,316, 84.4%) were compared those with MSI (n = 427, 15.6%). RESULTS: Baseline characteristics, including sex, race, and underlying comorbidities, were similar between groups. MSS patients had lower rates of high-risk pathologic features and higher rates of receiving multi-agent chemotherapy. On Kaplan-Meier analysis, median OS in the MSS group was improved compared with the MSI group (41.1 mo vs. 33.2 mo, p < 0.01). On multivariate analysis MSI status remained associated with worse OS (HR: 1.21 95% CI: 1.01-1.46, p = 0.04). CONCLUSIONS: This national analysis of CRLM validates MSI status as a biomarker to guide clinical decision-making due to the associated poor prognosis.

RESUMO

OBJECTIVE: Minority patients with lung cancer are less likely to undergo surgical resection and experience worse survival than non-Hispanic White patients. Currently, 40% of thoracic surgeons require smoking cessation before surgery, which may disproportionately affect minority patients. Our objective was to assess the risk of smoking status on postoperative morbidity and mortality among patients with lung cancer. METHODS: A prospectively maintained institutional database was queried for all patients who underwent surgical resection of a primary lung malignancy between 2006 and 2020. Operative mortality, major morbidity, and a composite of morbidity and mortality were compared between current smokers and prior smokers. RESULTS: A total of 601 patients underwent resection, and 236 (39.3%) were current smokers. Current smokers were more likely to be younger (P < .01), to have a greater pack-years history (P = .03), and to have worse pulmonary function test results (P < .01). Pretreatment stage, surgical approach, and extent of resection were similar between groups. There was no difference in operative mortality (0.9% vs 1.9%, P = .49), major morbidity (12.7% vs 9.3%, P = .19), or composite major morbidity and mortality between groups (13.1% vs 9.3%, P = .14). After adjusting for pulmonary function status, current smoking status was not associated with mortality or major morbidity on multivariable logistic regression (odds ratio, 1.51; 95% confidence interval, 0.76-3.03, P = .24). CONCLUSIONS: Current smokers experienced similar rates of mortality and major morbidity as prior smokers. In the context of continued racial and ethnic disparities in lung cancer survival, in particular decreased resection rates among minorities, smoking cessation requirements should not delay or prevent operative intervention for lung cancer.

RESUMO

BACKGROUND: Liver transplant recipients with persistent renal dysfunction may be prioritized on the kidney transplant waitlist based on the Organ Procurement and Transplantation Network "safety-net" policy implemented in 2017. The aim of this study was to evaluate the utilization of kidney transplant and posttransplant outcomes, of liver transplant recipients with persistent renal dysfunction before and after implementation of the Organ Procurement and Transplantation Network kidney safety-net policy and standardization of simultaneous liver-kidney requirements. METHODS: Using the United Network for Organ Sharing database from January 2015 to March 2019, outcomes of liver transplant recipients listed for kidney transplant and the subset who received kidney after liver transplants were compared before and after policy implementation. RESULTS: Liver transplant recipients listed for kidney transplant increased from 58 to 200, and kidney after liver transplants increased from 29.3% to 42.5% after safety-net policy implementation. Post-policy kidney after liver transplants received more local organs (91.8% vs 70.6%, P = .03) and trended toward shorter waitlist time (47 [17-123] vs 84 [37-226] days, P = .051). The pre- and post-policy cohorts had similar (P > .05) kidney donor profile index (0.43 [0.27-0.69] vs 0.42 [0.28-0.58]) and delayed graft function (11.8% vs 14.1%). Patient, kidney graft, and liver graft survival were similar (P > .05) between pre and post-policy cohorts. Patient and kidney graft survival were similar between kidney after liver transplants and propensity score-matched kidney transplant alone recipients. Patient, kidney, and liver graft survival were similar between kidney after liver transplants and propensity score-matched simultaneous liver-kidney transplant recipients. CONCLUSION: This study demonstrates that after Organ Procurement and Transplantation Network "safety-net" policy implementation, there has been an increase in liver transplant recipients with renal dysfunction who are listed for and undergo kidney transplant with excellent short-term results.

RESUMO

BACKGROUND: In 2004, the European Study Group for Pancreatic Cancer (ESPAC)-1 long-term data concluded that adjuvant chemotherapy provided a survival benefit for patients with pancreatic ductal adenocarcinoma (PDAC), whereas adjuvant chemoradiation was associated with worse overall survival. In this study, we investigated how long it took for US practice patterns to change following this trial. METHODS: The National Cancer Database was used to identify patients with stage I-III PDAC who underwent R0 or R1 resection followed by adjuvant chemotherapy or chemoradiation between 1998 and 2015. A multivariate analysis was performed to determine predictors of receiving adjuvant chemoradiation in the post-ESPAC-1 era. RESULTS: Between 1998 and 2015, adjuvant chemotherapy use increased from 2.9% to 51.6%, whereas adjuvant chemoradiation decreased from 49.5% to 22.9%. In 2010, adjuvant chemotherapy utilization surpassed that of chemoradiation. For patients diagnosed in the post-ESPAC-1 era, adjuvant chemotherapy (n = 7733) and chemoradiation (n = 6969) groups were compared. Patients who underwent adjuvant chemoradiation were younger, had private insurance, underwent surgery at nonacademic centers, and had more pathologically advanced cancers (all P < 0.01). After 2010, R1 resection was the strongest independent predictor of adjuvant chemoradiation use by multivariate analysis (OR 2.05, CI 1.8-2.3, P < 0.01). CONCLUSIONS: Adjuvant chemotherapy use exceeded that of adjuvant chemoradiation 6 y after the final publication of ESPAC-1 in 2004, highlighting the challenges of disseminating and adopting clinical data. After 2010, R1 disease was the most significant predictor of receiving adjuvant chemoradiation. Prospective studies are underway to definitively address the role of adjuvant chemoradiation in PDAC.

RESUMO

BACKGROUND: Level 1 evidence for multimodal treatment of resectable gastric adenocarcinoma from the Intergroup 0116 (2001) and MAGIC (2006) trials demonstrated survival benefit of adjuvant chemoradiation (CRT) and perioperative chemotherapy, respectively. We evaluated the adoption of evidence-based treatment in the post-MAGIC era and its impact on survival. METHODS: A total of 7058 patients with resectable gastric adenocarcinoma undergoing definitive surgical resection between 2004 and 2015 were analyzed using the National Cancer Database. RESULTS: Over the study period, the proportion of patients receiving adjuvant CRT decreased from 19.1% to 9.1%, while perioperative chemotherapy increased from 1.9% to 28.6%. Utilization of perioperative chemotherapy surpassed adjuvant CRT in 2011. Evidence-based treatment (either perioperative chemotherapy or adjuvant CRT) had better overall survival (OS) than other treatments for clinical stage II-III patients (p < 0.05). On multivariate analysis of the whole study period, evidence-based treatments were associated with better OS (HR 0.67 [0.60-0.74], p < 0.05). Only 360/1262 (28.5%) patients in the perioperative chemotherapy group completed postoperative therapy, which was associated with improved OS (p < 0.05). For clinical stage III patients (n = 2402), only 806 (33.6%) received evidence-based treatment, while 487 (22.2%) underwent surgery alone. On multivariate analysis of these patients between 2010 and 2015, both perioperative chemotherapy (HR 0.49 [0.35-0.68]) and adjuvant CRT (HR 0.31 [0.21-0.44]) were associated with better OS than surgery alone (p < 0.05). CONCLUSIONS: Since the INT-0116 and MAGIC trials, utilization of evidence-based treatments for resectable gastric adenocarcinoma has increased, with perioperative chemotherapy surpassing adjuvant CRT as the preferred practice. However, overall utilization of these regimens remains quite low nationally despite association with improved OS.

RESUMO

BACKGROUND: Preoperative narcotic use impacts hospital cost and outcomes in surgical patients, but the underlying reasons are unclear. METHODS: A single-center retrospective analysis was performed on surgical patients admitted with intestinal obstruction (2010-2014). Patients were grouped into active opioid and nonopioid user cohorts. Active opioid use was defined as having an opioid prescription overlapping the date of admission. Chronic opioid use was defined by duration of use ≥ 90 days. Admission or intervention due to opioid-related illness was determined through consensus decision of 2 independent, blinded clinicians. Primary end point was the effect of active opioid use on hospital resource utilization. RESULTS: During the study period, 296 patients were admitted with a primary diagnosis of intestinal obstruction. Active opioid users accounted for 55 (18.6%) of these patients, with a median length of opioid use of 164 days (interquartile range 54-344 days). Average length of use was 164 days, with the majority of active users (n = 42, 76.4%) meeting criteria for chronic use. A subgroup analysis of active users demonstrated that opioid-related conditions were responsible for 10 admissions (18.2%) and 2 readmissions (3.6%). Among active users requiring surgical intervention, 3 procedures (21.4%) were due to opioid-related illnesses. Median hospital length of stay was 2 days longer (8 vs 6 days) and hospital costs were greater ($12,241 vs $8489) among active users (P < .05 each). CONCLUSION: Active opioid users are predisposed to avoidable admissions and interventions for opioid-related illnesses. Efforts to address opioid use in the surgical population may improve patient outcomes and health care spending.

RESUMO

BACKGROUND: Proximal (duodenal) small bowel adenocarcinomas have a worse prognosis than distal (jejuno-ileal) tumors, but differences in patient, tumor, and treatment factors between locations remain unclear. METHODS: Patients in the National Cancer Database with surgically resected pathologic stage I-IV small bowel adenocarcinomas between 2004 and 2015 were analyzed. Clinical stage IV patients were excluded. RESULTS: Proximal tumors (n = 3767) were more likely to be higher grade (OR 1.52, CI 1.22-1.85 for moderately; OR 1.83, CI 1.49-2.33 for poorly differentiated, P < 0.01 for both) and have positive lymph nodes (OR 2.04, CI 1.30-3.23, P < 0.01), while distal tumors (n = 3252) were likely to be larger (OR 1.31, CI 1.07-1.60 for size > 5 cm, P < 0.01). Proximal tumors were associated with worse overall survival (OS) and stage-specific survival compared with distal tumors (all P < 0.01). Cox regression analysis of the entire cohort showed worse survival with community versus academic cancer programs, higher comorbidity scores, pathologic stage IV, poorly differentiated histology, positive nodal or margin status, and proximal location, while female gender, larger tumor size, and chemotherapy predicted better survival. On separate Cox regression analyses of each location, neoadjuvant chemotherapy was associated with better OS in the proximal cohort (HR 0.70, CI 0.55-0.88, P < 0.01), while adjuvant chemotherapy was associated with better OS for both proximal (HR 0.49, CI 0.42-0.57, P < 0.01) and distal tumors (HR 0.68, CI 0.57-0.81, P < 0.01). CONCLUSIONS: Proximal small bowel adenocarcinomas are associated with worse overall and stage-specific survival. This may be due to tumor biologic differences as proximal tumors were more likely to have higher grade. Future studies should further investigate differences between proximal and distal tumors to guide targeted treatment algorithms.

RESUMO

BACKGROUND: Appendiceal adenocarcinoma with signet ring cells (SCA) is associated with worse overall survival (OS), and it is unclear whether cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) should be pursued in this patient population. We assessed the prognostic implications of signet ring cells in patients with appendiceal adenocarcinoma and peritoneal carcinomatosis undergoing CRS-HIPEC. METHODS: The US HIPEC Collaborative, a 12-center, multi-institutional database of patients undergoing CRS-HIPEC, was reviewed for patients with SCA. Univariate and multivariate analyses were performed. RESULTS: Of 514 patients undergoing CRS-HIPEC for appendiceal adenocarcinoma, 125 (24%) had SCA. The SCA and non-SCA groups had similar baseline characteristics. SCA had worse OS compared with non-SCA (32.0 vs 91.4 months, p < 0.001). In univariate analysis for only SCA cases, there was worse OS in patients with poorly differentiated tumors, positive lymph nodes, LVI, PCI > 20, or incomplete cytoreduction (CC-2/3). However, multivariate analysis showed only positive lymph nodes (HR 1.14 [95% CI 1.00-1.31], p = 0.04), poor differentiation (5.60 [1.29-24.39], p = 0.02), and incomplete cytoreduction (4.90 [1.11-12.70], p = 0.03) were independently associated with decreased OS for SCA. CONCLUSION: While signet cells are a negative prognostic feature, they should not be a contraindication to CRS-HIPEC in patients with well-moderately differentiated tumors with negative lymph nodes, where complete cytoreduction can be achieved.

RESUMO

BACKGROUND: Salvage and delayed esophagectomy after chemoradiation therapy (CRT) have been associated with increased morbidity and mortality, but recent series have shown similar outcomes compared to timely esophagectomy. We aim to evaluate outcomes for delayed and salvage esophagectomy for esophageal adenocarcinoma utilizing a large national database. METHODS: The National Cancer Database for 2004 to 2014 was queried for patients with clinical stage II or III esophageal adenocarcinoma who underwent preoperative CRT and esophagectomy. Patients who underwent surgery <90 days after CRT were defined as the timely esophagectomy group (n = 7822), and those who underwent surgery ≥90 days after CRT were defined as the delayed esophagectomy group (n = 667). RESULTS: A total of 8489 patients met our inclusion criteria. The median post-CRT interval was 49 days (range, 40-61 days) for the timely esophagectomy group and 109 days (range, 97-132 days) for the delayed esophagectomy group. The delayed group was more likely to be of black race (2.3% vs 1.2%; P < .01) and more likely to have Medicare (47.9% vs 39.8%; P < .001). There were no significant between-group differences in chemotherapy regimens (P = .17), radiation dose (P = .18), or surgical approach (P = .48). The delayed esophagectomy group had higher rates of pathological complete response (22.2% vs 18.6%; P = .043) and 90-day postoperative mortality (10.4% vs 7.8%; P < .01). On multivariate analysis, delayed esophagectomy was not independently associated with decreased overall survival. CONCLUSIONS: In this large retrospective database study, despite increased perioperative mortality, delayed and salvage esophagectomy for adenocarcinoma appear to have similar long-term survival as timely esophagectomy. Delayed and salvage esophagectomy may be offered to patients who do not receive timely esophagectomy after CRT.

RESUMO

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) results in significant morbidity and readmissions. Previous studies have been limited by single-institution design or lack of tumor details in the database used. METHODS: The 12-institution US HIPEC Collaborative Database was queried between 1999 and 2017. Preoperative and intraoperative patient and tumor details were analyzed for associations with readmissions. RESULTS: A total of 2017 of 2372 cases were included in the analysis. The 30-day readmission rate was 15.9% (n = 321). Common indications for readmission included failure to thrive (29.9%), infection (23.6%), and ileus/bowel obstruction (15.1%). The readmitted cohort had more complications, including intra-abdominal abscess (21.2% vs 6.2%), ileus (28.0% vs 17.2%), anastomotic leak (11.2% vs 2.2%), enteric fistula (5.6% vs 1.5%), deep venous thrombosis (6.2% vs 2.5%), and pulmonary embolism (6.9% vs 2.5%). Factors independently associated with readmission (p < 0.05) included ECOG score ≥ 3 (OR 3.4), depression (OR 2.4), total parenteral nutrition (OR 3.6), low anterior resection or partial colectomy (OR 2.0), and stoma creation (OR 2.2). Factors not associated included neoadjuvant chemotherapy, peritoneal cancer index, and completeness of cytoreduction. Readmission rate between 31 and 90 days was 3.9% (n = 78). Independent predictors (p < 0.05) included operative time (OR 1.1), low anterior resection or partial colectomy (OR 1.7), and stoma creation (OR 2.2). CONCLUSIONS: In the largest study to date examining readmissions after CRS-HIPEC, 30-day readmission rate was 15.9%. Tumor factors failed to predict readmission, whereas preoperative functional status and depression along with individual cytoreductive procedures predicted readmission. Patients with these risk factors or postoperative complications may benefit from closer post-discharge monitoring.

RESUMO

BACKGROUND: The impact of recent preoperative opioid exposure on outcomes of colorectal surgery is unclear. Our aim was to evaluate the impact of preoperative opioid use on outcomes and opioid prescribing patterns after colorectal surgery. METHODS: We performed a retrospective review of all patients undergoing elective resection at a single institution from 2015 to 2017. Primary outcomes included in-hospital narcotic use and cost. Secondary outcomes included postoperative surgical outcomes and discharge prescribing patterns. RESULTS: A total of 390 patients underwent elective colorectal surgery, of whom 63 (16%) had a recent history of preoperative opioid use. Opioid users had similar age, sex, American Society of Anesthesiologists score, and operative indication compared with opioid-naïve patients (P > .05 for each). Postoperatively, the 30-day readmission rate was greater among opioid users (18% vs 9%, P = .03). Opioid users had greater total narcotic use (218 morphine milligram equivalents vs 111 morphine milligram equivalents, P = .04) and direct costs ($11,165 vs $8,911, P < .01). These patients were also more likely to require an opioid prescription on discharge (90% vs 68%, P < .01) and an opioid refill within 30 days (54% vs 21%, P < .01). CONCLUSION: Recent preoperative opioid exposure among colorectal surgery patients was associated with increased opioid consumption and costs. Moreover, unadjusted analysis was pertinent for more readmissions after surgery among preoperative opioid users. This work underscores the negative impact of preoperative, chronic opioid use on surgical outcomes and highlights the need for developing protocols to minimize perioperative narcotics.

RESUMO

BACKGROUND: Patients undergoing complex surgery at safety net hospitals have been shown to suffer inferior short-term outcomes. Liver transplantation, one of the most complex surgical interventions, is offered at certain safety net hospitals. We sought to identify whether patients undergoing liver transplantation at safety net hospitals have inferior outcomes compared with lower burden centers. METHODS: Using a link between the University HealthSystem Consortium and Scientific Registry of Transplant Recipient databases, we identified 11,047 patients undergoing liver transplantation at 63 centers between 2009 and 2012. Hospitals were grouped by safety net burden, defined as the proportion of Medicaid or uninsured patient encounters during that time. The highest quartile (safety net hospitals) was compared to medium- and low-burden hospitals regarding recipient and donor characteristics, perioperative outcomes, and long-term survival. RESULTS: Liver transplantation recipients at safety net hospitals were more often black and of lower socioeconomic status (P < .01), but had similar model for end-stage liver disease scores (20 vs 20 vs 18) compared with median-burden hospitals and low burden hospitals. Length of stay and readmission rates were similar; however, safety net hospitals demonstrated higher in-hospital mortality (5.2% vs 4.5% vs 2.9%, P < .01). Despite this, there was no significant difference in overall patient or graft survivals in patients who underwent liver transplantation at safety net hospitals and survived the perioperative setting at a median follow-up of 2 years (P > .05). CONCLUSION: Despite differences in perioperative outcomes at safety net hospitals, these centers achieve noninferior long-term patient and graft survival for potentially vulnerable patients requiring liver transplantation. Strict care standardization, as achieved in liver transplantation, may be a mechanism by which outcomes can be improved at safety net hospitals after other complex surgical procedures.

RESUMO

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) remains a formidable operation associated with considerable morbidity. It is unclear how often these patients require reoperation for postoperative complications and if the need for reoperations leads to worse long-term outcomes. METHODS: The Peritoneal Surface Malignancy Database at a single center was retrospectively queried. Out of 149 entries, 141 HIPECs performed between 2012 and 2018 met inclusion criteria. Patients were categorized based on early reoperation (<60 d after HIPEC), and demographic and tumor factors were compared using univariate analyses. Recurrence was calculated for patients with complete cytoreduction and overall survival analyzed using the Kaplan-Meier method. RESULTS: There were 15 reoperations after 141 HIPECs (10.6%). Median duration between HIPEC and reoperation was 18 d. Indications for reoperation included intra-abdominal infection (n = 5), bowel obstruction (n = 4), wound infection (n = 3), bleeding (n = 2), and evisceration (n = 1). There were no identified patient- or tumor-related risk factors for reoperation. Reoperations were associated with longer hospital length of stay (19 versus 9 d, P = 0.005) and 30-d readmissions (46.7% versus 12.8%, P = 0.003). There was no significant difference in 3-year recurrence-free survival, but there was a significant association between reoperation and 3-year overall survival (38.0% versus 71.9%, P = 0.03). CONCLUSIONS: Complications requiring reoperation after HIPEC lead to increased short-term morbidity, longer hospital length of stay, and most importantly, reduced overall survival. Further studies investigating interventions to decrease complications and reduce reoperation rates are needed to improve outcomes after HIPEC.

RESUMO

The use of donation after circulatory death (DCD) liver allografts has been constrained by limitations in the duration of donor warm ischemia time (DWIT), donor agonal time (DAT), and cold ischemia time (CIT). The purpose of this study is to assess the impact of longer DWIT, DAT, and CIT on graft survival and other outcomes in DCD liver transplants. The Scientific Registry of Transplant Recipients was queried for adult liver transplants from DCD donors between 2009 and 2015. Donor, recipient, and center variables were included in the analysis. During the study period, 2107 patients underwent liver transplant with DCD allografts. In most patients, DWIT and DAT were <30 minutes. DWIT was <30 minutes in 1804 donors, between 30 and 40 minutes in 248, and >40 minutes in 37. There was no difference in graft survival, duration of posttransplant hospital length of stay, and readmission rate between DCD liver transplants from donors with DWIT <30 minutes and DWIT between 30 and 40 minutes. Similar outcomes were noted for DAT. In the multivariate analysis, DAT and DWIT were not associated with graft loss. The predictors associated with graft loss were donor age, donor sharing, CIT, recipient admission to the intensive care unit, recipient ventilator dependence, Model for End-Stage Liver Disease score, and low-volume transplant centers. Any CIT cutoff >4 hours was associated with increased risk for graft loss. Longer CIT was also associated with a longer posttransplant hospital stay, higher rate of primary nonfunction, and hyperbilirubinemia. In conclusion, slightly longer DAT and DWIT (up to 40 minutes) were not associated with graft loss, longer posttransplant hospitalization, or hospital readmissions, whereas longer CIT was associated with worse outcomes after DCD liver transplants.
