Pilot Study to Optimize Goal-directed Hemodynamic Management During Pancreatectomy.

INTRODUCTION: Intraoperative goal-directed hemodynamic therapy (GDHT) is a cornerstone of enhanced recovery protocols. We hypothesized that use of an advanced noninvasive intraoperative hemodynamic monitoring system to guide GDHT may decrease intraoperative hypotension (IOH) and improve perfusion during pancreatic resection. METHODS: The monitor uses machine learning to produce the Hypotension Prediction Index to predict hypotensive episodes. A clinical decision-making algorithm uses the Hypotension Prediction Index and hemodynamic data to guide intraoperative fluid versus pressor management. Pre-implementation (PRE), patients were placed on the monitor and managed per usual. Post-implementation (POST), anesthesia teams were educated on the algorithm and asked to use the GDHT guidelines. Hemodynamic data points were collected every 20 s (8942 PRE and 26,638 POST measurements). We compared IOH (mean arterial pressure <65 mmHg), cardiac index >2, and stroke volume variation <12 between the two groups. RESULTS: 10 patients were in the PRE and 24 in the POST groups. In the POST group, there were fewer minimally invasive resections (4.2% versus 30.0%, P = 0.07), more pancreaticoduodenectomies (75.0% versus 20.0%, P < 0.01), and longer operative times (329.0 + 108.2 min versus 225.1 + 92.8 min, P = 0.01). After implementation, hemodynamic parameters improved. There was a 33.3% reduction in IOH (5.2% ± 0.1% versus 7.8% ± 0.3%, P < 0.01, a 31.6% increase in cardiac index >2.0 (83.7% + 0.2% versus 63.6% + 0.5%, P < 0.01), and a 37.6% increase in stroke volume variation <12 (73.2% + 0.3% versus 53.2% + 0.5%, P < 0.01). CONCLUSIONS: Advanced intraoperative hemodynamic monitoring to predict IOH combined with a clinical decision-making tree for GDHT may improve intraoperative hemodynamic parameters during pancreatectomy. This warrants further investigation in larger studies.

A self-selecting prophecy: prevalence of burnout in surgical fellows.

BACKGROUND: Burnout has become a prominent topic, yet there are limited data on the manifestation of this phenomenon among surgical fellows. The goal of this study is to elucidate the prevalence of burnout and determine if there are protective or predisposing factors in surgical fellowship training. METHODS: A confidential electronic survey was distributed to Fellowship Council accredited fellows during the 2020-2021 academic year. Demographic information and training characteristics were queried. The fellows were then asked to complete the Maslach Burnout Inventory (MBI), Perceived Stress Scale (PSS), Short Grit Scale (SGS), Satisfaction with Life Scale (SLS), and General Self-Efficacy Scale (SE). Data were analyzed using p values of ≤ 0.05 as statistically significant. RESULTS: At the end of the survey period, 92 out of 196 (46.9%) fellowship trainees responded. 69.6% of respondents identified as men, 29.7% as international medical school graduates (IMGs), and 15.3% non-US IMGs. Based on criteria defined by the MBI, there was an 8.4% rate of burnout. Most respondents noted low stress levels (62.3%), good satisfaction with life (58.9%), a moderate amount of grit, and a high level of self-esteem. On comparative analysis, fellows with burnout had significantly higher stress levels, lower levels of satisfaction with life, and less self-esteem. CONCLUSIONS: Overall, there was a low rate of burnout among fellows. We suggest this may be reflective of a self-selecting effect, as trainees who choose to undergo additional training may be less likely to experience this syndrome. In addition, there may be a protective factor during fellowship that results from inherent mentoring, increased specialization, and autonomy. Further investigation of the predisposing factors to burnout in fellowship trainees is warranted based on the results of this study.

Attending Surgeon Influences Operative Time More Than Resident Level in Laparoscopic Cholecystectomy.

BACKGROUND: Prior studies on laparoscopic cholecystectomy (LC) have concluded that resident involvement lengthens operative time without impacting outcomes. However, the lack of effect of resident level on operative duration has not been explained. We hypothesized that attending-specific influence on average operative time for LC is more pronounced than resident post-graduate year level. MATERIALS AND METHODS: We retrospectively analyzed all LC cases performed on patients 18 y and older between November 2018 and March 2020 at 2 academic medical center-affiliated hospitals. Regression models were used to compare operative times, conversion to open rates, and complication rates by attending surgeon and resident level. RESULTS: Nine hundred twenty-five LCs were performed over the study period, 862 (93.1%) with resident participation. Of the 44.5% variation in operative time was explained by differences in attending surgeon, as compared to 11.0% attributable to differences in resident level (P < 0.0001). This effect persisted after adjusting for patient and disease factors (33.0% versus 7.1%, P < 0.0001). Neither attending surgeon (P = 0.80), nor the level of the involved resident (P = 0.94) demonstrated a significant effect on the conversion-to-open rate (4.9%). Similarly, neither the attending surgeon (P = 0.33), nor resident level (P = 0.81) significantly affected the complication rate (8.58%). CONCLUSIONS: Operative time for LC is primarily determined by patient- and disease-specific factors; resident level has no effect on conversion to open or complication rates. Attending influence on operative time was more pronounced than resident level influence. These findings suggest attending surgeon-related factors are more important than resident experience in determining operative duration for LC.

Emotional Regulation in Surgery: Fostering Well-Being, Performance, and Leadership.

Emotional regulation is increasingly gaining acceptance as a means to improve well-being, performance, and leadership across high-stakes professions, representing innovation in thinking within the field of surgical education. As one part of a broader cognitive skill set that can be trained and honed, emotional regulation has a strong evidence base in high-stress, high-performance fields. Nevertheless, even as Program Directors and surgical educators have become increasingly aware of this data, with emerging evidence in the surgical education literature supporting efficacy, hurdles to sustainable implementation exist. In this white paper, we present evidence supporting the value of emotional regulation training in surgery and share case studies in order to illustrate practical steps for the development, adaptation, and implementation of emotional regulation curricula in three key developmental contexts: basic cognitive skills training, technical skills acquisition and performance, and preparation for independence. We focus on the practical aspects of each case to elucidate the challenges and opportunities of introducing and adopting a curricular innovation into surgical education. We propose an integrated curriculum consisting of all three applied contexts for emotional regulation skills and advocate for the dissemination of such a longitudinal curriculum on a national level.

Aspartate Aminotransferase-to-Platelet Ratio Index Predicts Liver Failure After Resection of Colorectal Liver Metastases.

BACKGROUND: Chemotherapy agents for metastatic colorectal cancer can cause liver injury, increasing the risk of post-hepatectomy liver failure after hepatectomy for metastases. The role of noninvasive fibrosis markers in this setting is not well established. AIMS: To evaluate the aspartate aminotransferase-to-platelet ratio index (APRI) as a predictor of postoperative liver failure. METHODS: The National Surgical Quality Improvement Program database was utilized to identify patients who received preoperative chemotherapy and underwent hepatectomy for colorectal metastases between 2015 and 2017. Concordance index analysis was conducted to determine APRI's contribution to the prediction of liver failure. The optimal cutoff value was defined and its ability to predict post-hepatectomy liver failure and perioperative bleeding were examined. RESULTS: A total of 2374 patients were identified and included in the analysis. APRI demonstrated to be a better predictor of postoperative liver failure than MELD score, with a statistically significant larger area under the curve. The optimal APRI cutoff value to predict liver failure was 0.365. The multivariable logistic regression showed that APRI ≥ 0.365 was independently associated with PHLF, odds ratio (OR) 2.51, 95% confidence interval (CI) 1.67-3.77, P < .0001. Likewise, APRI ≥ 0.365 was independently associated with perioperative bleeding complications requiring transfusions, OR 1.41, 95% CI 1.13-1.77, P = 0.002. MELD score was not statistically associated with PHLF or bleeding complications. CONCLUSIONS: APRI was independently associated with post-hepatectomy liver failure and perioperative bleeding requiring transfusions after resection of colorectal metastases in patients who received preoperative chemotherapy. Concordance index showed APRI to add significant contribution as a predictor of postoperative liver failure.

Minimally invasive vs open pancreatoduodenectomy on oncological adequacy: a propensity score-matched analysis.

BACKGROUND: The adoption of minimally invasive pancreatoduodenectomy (MIPD) has increased over the last decade. Most of the data on perioperative and oncological outcomes derives from single-center high-volume hospitals. The impact of MIPD on oncological outcomes in a multicenter setting is poorly understood. METHODS: The National Cancer Database was utilized to perform a propensity score matching analysis between MIPD vs open pancreatoduodenectomy (OPD). The primary outcomes were lymphadenectomy ≥ 15 nodes and surgical margins. Secondary outcomes were 90-day mortality, length of stay, and overall survival. RESULTS: A total of 10,246 patients underwent pancreatoduodenectomy for ductal adenocarcinoma between 2010 and 2016. Among these patients, 1739 underwent MIPD. A propensity score matching analysis with a 1:2 ratio showed that the rate of lymphadenectomy ≥ 15 nodes was significantly higher for MIPD compared to OPD, 68.4% vs 62.5% (P < .0001), respectively. There was no statistically significant difference in the rate of positive margins, 90-day mortality, and overall survival. OPD was associated with an increased rate of length of stay > 10 days, 36.6% vs 33% for MIPD (P < .01). Trend analysis for the patients who underwent MIPD revealed that the rate of adequate lymphadenectomy increased during the study period, 73.1% between 2015 and 2016 vs 63.2% between 2010 and 2012 (P < .001). In addition, the rate of conversion to OPD decreased over time, 29.3% between 2010 and 2012 vs 20.2% between 2015 and 2016 (P < .001). CONCLUSION: In this propensity score matching analysis, the MIPD approach was associated with a higher rate of adequate lymphadenectomy and a shorter length of stay compared to OPD. The surgical margins status, 90-day mortality, and overall survival were similar between the groups.

The Role of Personal Accomplishment in General Surgery Resident Well-being.

OBJECTIVE: To investigate the association of personal accomplishment (PA) with the other subscales, assess its association with well-being outcomes, and evaluate drivers of PA by resident level. BACKGROUND: Most studies investigating physician burnout focus on the emotional exhaustion (EE) and depersonalization (DP) subscales, neglecting PA. Therefore, the role of PA is not well understood. METHODS: General surgery residents were surveyed following the 2019 American Board of Surgery In-Training Examination regarding their learning environment. Pearson correlations of PA with EE and DP were assessed. Multivariable logistic regression models assessed the association of PA with attrition, job satisfaction, and suicidality and identified factors associated with PA by PGY. RESULTS: Residents from 301 programs were surveyed (85.6% response rate, N = 6956). Overall, 89.4% reported high PA, which varied by PGY-level (PGY1: 91.0%, PGY2/3: 87.7%, PGY4/5: 90.2%; P = 0.02). PA was not significantly correlated with EE (r = -0.01) or DP (r = -0.08). After adjusting for EE and DP, PA was associated with attrition (OR 0.60, 95%CI 0.46-0.78) and job satisfaction (OR 3.04, 95%CI 2.45-3.76) but not suicidality (OR 0.72, 95%CI 0.48-1.09). Although the only factor significantly associated with PA for interns was resident cooperation, time in operating room and clinical autonomy were significantly associated with PA for PGY2/3. For PGY4/5s, PA was associated with time for patient care, resident cooperation, and mentorship. CONCLUSION: PA is a distinct metric of resident well-being, associated with job satisfaction and attrition. Drivers of PA differ by PGY level and may be targets for intervention to promote resident wellness and engagement.

Gallbladder Cancer Surgery in the United States: Lymphadenectomy Trends and Impact on Survival.

BACKGROUND: Gallbladder cancer has a poor prognosis, and surgery is the only curative treatment. However, lymphadenectomy has been underperformed. We evaluate the trend of lymphadenectomy in the United States and its impact on survival. METHODS: This is a cohort study of patients who underwent gallbladder cancer surgery between 2004 and 2016. Trend analysis of the rate of lymphadenectomy and the number of lymph nodes (LNs) removed were examined. The impact of lymph node status and different LN staging systems on survival was examined. RESULTS: Of the 4577 patients identified, 69.9% were female, the mean age was 71.0 (±12.4), 87.2% had ≥ T2, and only 50.3% (n = 2302) received lymphadenectomy. Although the rate of lymphadenectomy and the number of LNs removed increased during the study period, both with P < 0.0001, the rate of patients who received examination of ≥6 LNs remained low, 13.6% in 2016. Adjusted regression analysis showed that patients without LN examination had worse overall survival than patients with LN positive disease, HR: 1.11 (95% CI: 1.01, 1.22). Concordance index analysis revealed that LN ratio (LNR) and Log odds of positive LN (LODDS) did not improve the ability of the American Joint Commission on Cancer (AJCC) staging in predicting 5-y survival rate. CONCLUSIONS: Lack of LN examination is associated with worse survival than LN positive disease. Although the rate of LN examination and number of LNs retrieved have increased from 2004 to 2016, they remained low. LNR and LODDS staging systems added no benefit to AJCC staging ability in predicting a 5-y survival rate.

Pediatric Firearm Injuries and Fatalities: Do Racial Disparities Exist?

OBJECTIVE: To evaluate racial disparities among White and Black pediatric firearm injury patients on a national level. BACKGROUND: Pediatric firearm-related morbidity and mortality are rising in the United States. There is a paucity of data examining racial disparities in those patients. METHODS: The Pediatric Trauma Quality Improvement Program (2017) was queried for pediatric (age ≤17 years) patients admitted with firearm injuries. Patients were stratified by race: White and Black. Injury characteristics were assessed. Outcomes were mortality, hospital length of stay, and discharge disposition. Hierarchical regression models were performed to determine predictors of mortality and longer hospital stays. RESULTS: A total of 3717 pediatric firearm injury patients were identified: Blacks (67.0%) and Whites (33.0%). The majority of patients were male (84.2%). The most common injury intent in both groups was assault (77.3% in Blacks vs in 45.4% Whites; P<0.001), followed by unintentional (21.1% vs 35.4%; P<0.001), and suicide (1.0% vs 14.0%; P<0.001). The highest fatality rate was in suicide injuries (62.6%). On univariate analysis, White children had higher mortality (17.5% vs 9.8%; P<0.001), longer hospital stay [3 (1-7) vs 2 (1-5) days; P = 0.021], and more psychiatric hospital admissions (1.3% vs 0.1%; P<0.001). On multivariate analysis, suicide intent was found to be an independent predictor of mortality (aOR 2.67; 95% CI 1.35-5.29) and longer hospital stay (ß + 4.13; P<0.001), while White race was not. CONCLUSION: Assault is the leading intent of injury in both Black and White children, but White children suffer more from suicide injuries that are associated with worse outcomes. LEVEL OF EVIDENCE: Level III Prognostic.

Significance of Lymph Node Resection After Neoadjuvant Therapy in Pancreatic, Gastric, and Rectal Cancers.

OBJECTIVE: Gastrointestinal cancers are increasingly being treated with NAT before surgical resection. Currently, quality metrics are linked to the number of LNs resected to determine subsequent treatment and prognosis. We hypothesize that NAT decreases LN metastasis, downstages patients, and decreases overall lymph node yields (LNY) compared to initial surgical resection. With increasing use of NAT, this brings into question the validity of quality metrics. METHODS: Gastric (stage II/III), pancreatic (stage I/II/III), and rectal cancers (stage II/III) (2010-2015) treated with surgery with/without NAT were identified in National Cancer Database. We evaluated total LNY and LN metastasis with/without NAT and clinical and pathological stage to evaluate rates of downstaging. RESULTS: A total of 7934 gastric, 15,908 pancreatic, and 21,354 rectal cancer patients were included of which 61.1%, 21.2%, and 85.7% received NAT, respectively. NAT patients were more likely to be downstaged (39.9% vs 11.1% gastric P< 0.001, 30.6% vs 3.2% pancreatic P< 0.001, 52.0% vs 16.3% rectal P< 0.001), have lower LNYs (18.8 vs 19.1 gastric P = 0.239, 18.4 vs 17.5 pancreatic P< 0.001, 15.7 vs 20.0 rectal P< 0.001) and have N0 pathologic disease (43.6% vs 26.7% gastric P< 0.001, 51.1% vs 30.9% pancreatic P< 0.001, 65.9% vs 49.4% rectal P< 0.001) when compared to initial surgical resection. CONCLUSION: NAT for gastrointestinal cancers results in overall lower LN yields, lower LN metastases, and significant downstaging of tumors. As all patients undergoing NAT receive multimodality therapy, LN yield recommendations may not be true quality metric changing.

Safe Cholecystectomy Multi-society Practice Guideline and State of the Art Consensus Conference on Prevention of Bile Duct Injury During Cholecystectomy.

BACKGROUND: BDI is the most common serious complication of laparoscopic cholecystectomy. To address this problem, a multi-society consensus conference was held to develop evidenced-based recommendations for safe cholecystectomy and prevention of BDI. METHODS: Literature reviews were conducted for 18 key questions across 6 broad topics around cholecystectomy directed by a steering group and subject experts from 5 surgical societies (Society of Gastrointestinal and Endoscopic Surgeons, Americas Hepato-Pancreato-Biliary Association, International Hepato-Pancreato-Biliary Association, Society for Surgery of the Alimentary Tract, and European Association for Endoscopic Surgery). Evidence-based recommendations were formulated using the grading of recommendations assessment, development, and evaluation methodology. When evidence-based recommendations could not be made, expert opinion was documented. A number of recommendations for future research were also documented. Recommendations were presented at a consensus meeting in October 2018 and were voted on by an international panel of 25 experts with greater than 80% agreement considered consensus. RESULTS: Consensus was reached on 17 of 18 questions by the guideline development group and expert panel with high concordance from audience participation. Most recommendations were conditional due to low certainty of evidence. Strong recommendations were made for (1) use of intraoperative biliary imaging for uncertainty of anatomy or suspicion of biliary injury; and (2) referral of patients with confirmed or suspected BDI to an experienced surgeon/multispecialty hepatobiliary team. CONCLUSIONS: These consensus recommendations should provide guidance to surgeons, training programs, hospitals, and professional societies for strategies that have the potential to reduce BDIs and positively impact patient outcomes. Development of clinical and educational research initiatives based on these recommendations may drive further improvement in the quality of surgical care for patients undergoing cholecystectomy.

A Protocol-Driven Reduction in Surgical Site Infections After Colon Surgery.

BACKGROUND: Surgical site infection (SSI) is an established quality indicator and predictor for adverse patient outcomes. Multiple strategies have been established to reduce SSI; however, optimum protocol remains unclear. The aim of the study was to assess the impact of established protocol on SSI after colon surgery. METHODS: We established a colon SSI bundle in 2017, which includes a chlorhexidine prescrub followed by chloraPrep, betadine wound wash, antibiotic infused irrigation, use of closure tray, and incision coverage with silver impregnated dressing. Retrospective analysis of a 2-y (2016-2017) prospectively collected before and after analysis of all patients undergoing elective colon surgery was performed. Patients were divided into two groups: preprotocol (PP: year 2016) and postprotocol (PoP: year 2017). Patients in the two groups were matched using propensity score matching for age, gender, comorbidities, Anesthesiology Severity Score, indication of procedure, and procedure type. Outcome measures were SSI, hospital length of stay, and readmission rate. RESULTS: A total of 328 patients were analyzed, and after propensity matching, 94 patients (PP:47 and PoP:47) were included. The mean age was 63.7 ± 16.4 y, 43.6% male, and 44.6% of procedures were performed laparoscopically. There was no difference in demographics, comorbidities, and procedure details between two groups. PoP patients had significantly lower superficial (odds ratio: 0.91 [0.74-0.98]; P = 0.045) and deep SSI (odds ratio:0.97 [0.65-0.99]; P = 0.048) than PP patients. PoP patient had shorter length of stay (P = 0.049) and trend toward lower readmission rate (P = 0.098) compared with PP patients and an 85% reduction in the Centers for Medicare and Medicaid Services standardized infection rate. CONCLUSIONS: Protocol-driven patient care improves patient outcomes. SSI bundle reduced SSI in patient undergoing colon surgery. Establishing national SSI bundles will help standardize care and help optimize patient outcomes.

Safe cholecystectomy multi-society practice guideline and state-of-the-art consensus conference on prevention of bile duct injury during cholecystectomy.

BACKGROUND: Bile duct injury (BDI) is the most common serious complication of laparoscopic cholecystectomy. To address this problem, a multi-society consensus conference was held to develop evidenced-based recommendations for safe cholecystectomy and prevention of BDI. METHODS: Literature reviews were conducted for 18 key questions across six broad topics around cholecystectomy directed by a steering group and subject experts from five surgical societies (SAGES, AHPBA IHPBA, SSAT, and EAES). Evidence-based recommendations were formulated using the GRADE methodology. When evidence-based recommendations could not be made, expert opinion was documented. A number of recommendations for future research were also documented. Recommendations were presented at a consensus meeting in October 2018 and were voted on by an international panel of 25 experts with greater than 80% agreement considered consensus. RESULTS: Consensus was reached on 17 of 18 questions by the Guideline Development Group (GDG) and expert panel with high concordance from audience participation. Most recommendations were conditional due to low certainty of evidence. Strong recommendations were made for (1) use of intraoperative biliary imaging for uncertainty of anatomy or suspicion of biliary injury; and (2) referral of patients with confirmed or suspected BDI to an experienced surgeon/multispecialty hepatobiliary team. CONCLUSION: These consensus recommendations should provide guidance to surgeons, training programs, hospitals, and professional societies for strategies that have the potential to reduce BDIs and positively impact patient outcomes. Development of clinical and educational research initiatives based on these recommendations may drive further improvement in the quality of surgical care for patients undergoing cholecystectomy.

Safety of Continued Clopidogrel Use in the Preoperative Course of Gastrointestinal Surgery: A Retrospective Cohort Study.

OBJECTIVE: Our study aimed to estimate postoperative bleeding risk in older adults taking clopidogrel before gastrointestinal (GI) surgery, to aid surgeons in decisions regarding clopigogrel cessation. SUMMARY BACKGROUND DATA: Balancing risks of postoperative bleeding associated with continued clopidogrel use and those associated with cessation is difficult for GI surgeons. METHODS: Using 100% Texas Medicare Claims Data from 2006 to 2011, we identified patients undergoing emergent GI surgery. We propensity score matched patients on clopidogrel before surgery to patients not on clopidogrel. Using conditional logistic regression, we compared risks of bleeding events at 1-month postdischarge between groups, adjusting for bleeding risk factors. RESULTS: In total, 1240 patients undergoing emergent GI surgery while treated with clopidogrel were matched to emergency GI surgery patients not treated with clopidogrel. The only significant preoperative differences between groups were higher percent of clopidogrel-treated patients with congestive heart failure, cholecystectomy, and lower percent of clopidogrel-treated patients with colectomy. Mean age was 76.91 (±7.06) and 76.70 (±7.05) years (P = 0.47), and 63.84% and 59.41% of operations were cholecystectomy, in the clopidogrel and nonclopidogrel groups (P = 0.18). In multivariable analyses adjusting for Elixhauser index, hyperlipidemia, confounding drugs, and surgery type, odds ratio for bleeding within 30 days of discharge in those exposed to clopidogrel compared with those not exposed was 1.60 (95% confidence interval, 1.08-2.38), with raw rates of bleeding 6.85% and 4.84%. CONCLUSIONS: Clopidogrel use in older adults through the preoperative period of GI surgery does not significantly increase bleeding events in the month after surgery.

A Prospective Randomized Multicenter Trial of Distal Pancreatectomy With and Without Routine Intraperitoneal Drainage.

OBJECTIVE: The objective of this study was to test the hypothesis that distal pancreatectomy (DP) without intraperitoneal drainage does not affect the frequency of grade 2 or higher grade complications. BACKGROUND: The use of routine intraperitoneal drains during DP is controversial. Prior to this study, no prospective trial focusing on DP without intraperitoneal drainage has been reported. METHODS: Patients undergoing DP for all causes at 14 high-volume pancreas centers were preoperatively randomized to placement of a drain or no drain. Complications and their severity were tracked for 60 days and mortality for 90 days. The study was powered to detect a 15% positive or negative difference in the rate of grade 2 or higher grade complications. All data were collected prospectively and source documents were reviewed at the coordinating center to confirm completeness and accuracy. RESULTS: A total of 344 patients underwent DP with (N = 174) and without (N = 170) the use of intraperitoneal drainage. There were no differences between cohorts in demographics, comorbidities, pathology, pancreatic duct size, pancreas texture, or operative technique. There was no difference in the rate of grade 2 or higher grade complications (44% vs. 42%, P = 0.80). There was no difference in clinically relevant postoperative pancreatic fistula (18% vs 12%, P = 0.11) or mortality (0% vs 1%, P = 0.24). DP without routine intraperitoneal drainage was associated with a higher incidence of intra-abdominal fluid collection (9% vs 22%, P = 0.0004). There was no difference in the frequency of postoperative imaging, percutaneous drain placement, reoperation, readmission, or quality of life scores. CONCLUSIONS: This prospective randomized multicenter trial provides evidence that clinical outcomes are comparable in DP with or without intraperitoneal drainage.

Patient and physician views of shared decision making in cancer.

CONTEXT: Engaging patients in shared decision making involves patient knowledge of treatment options and physician elicitation of patient preferences. OBJECTIVE: Our aim was to explore patient and physician perceptions of shared decision making in clinical encounters for cancer care. DESIGN: Patients and physicians were asked open-ended questions regarding their perceptions of shared decision making throughout their cancer care. Transcripts of interviews were coded and analysed for shared decision-making themes. SETTING AND PARTICIPANTS: At an academic medical centre, 20 cancer patients with a range of cancer diagnoses, stages of cancer and time from diagnosis, and eight physicians involved in cancer care were individually interviewed. DISCUSSION AND CONCLUSIONS: Most physicians reported providing patients with written information. However, most patients reported that written information was too detailed and felt that the physicians did not assess the level of information they wished to receive. Most patients wanted to play an active role in the treatment decision, but also wanted the physician's recommendation, such as what their physician would choose for him/herself or a family member in a similar situation. While physicians stated that they incorporated patient autonomy in decision making, most provided data without making treatment recommendations in the format preferred by most patients. We identified several communication gaps in cancer care. While patients want to be involved in the decision-making process, they also want physicians to provide evidence-based recommendations in the context of their individual preferences. However, physicians often are reluctant to provide a recommendation that will bias the patient.

Reduced morbidity with minimally invasive distal pancreatectomy for pancreatic adenocarcinoma.

BACKGROUND: Minimally invasive distal pancreatectomy (MISDP) has been shown to be safe relative to open distal pancreatectomy (ODP). However, MISDP has been slow to adopt for pancreatic adenocarcinoma (PDAC). This study sought to compare outcomes following MISDP vs. ODP for PDAC. METHODS: Data were prospectively collected from 2011 to 2014 for DP by the American College of Surgeons-National Surgical Quality Improvement Program. Patients without PDAC on surgical pathology were excluded. Impact of minimally invasive approach on morbidity and mortality was analyzed using two-way statistical analyses. RESULTS: Of 6198 patients undergoing DP, 501 (7.5%) had a pathologic diagnosis of PDAC. MISDP was undertaken in 166 (33.1%) patients, ODP was performed in 335 (66.9%). MISDP and ODP were not different in preoperative comorbidities or pathologic stage. Overall morbidity (MISDP 31%, ODP 42%; p = 0.024), transfusion (MISDP 6%, ODP 23%; p = 0.0001), pneumonia (MISDP 1%, ODP 7%; p = 0.004), surgical site infections (MISDP 8%, OPD 17%; p = 0.013), sepsis (MISDP 2%, ODP 8%; p = 0.007), and length of stay (MISDP 5.0 days, ODP 7.0 days; p = 0.009) were lower in the MIS group. Mortality (MISDP 0%, ODP 1%; p = 0.307), pancreatic fistula (MISDP 12%, ODP 19%; p = 0.073), and delayed gastric emptying (MISDP 3%, ODP 7%; p = 0.140) were similar. CONCLUSIONS: This analysis of a large multi-institution North American experience of DP for treatment of pancreatic adenocarcinoma suggests that short-term postoperative outcomes are improved with MISDP.

Pancreatoduodenectomy with venous or arterial resection: a NSQIP propensity score analysis.

INTRODUCTION: Vascular resection during pancreatoduodenectomy (PD) is being performed more frequently. Our aim was to analyze the outcomes of PD with and without vascular resection in a large, multicenter cohort. METHODS: Patient data were gathered from 43 institutions as part of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) Pancreatectomy Demonstration Project. Over a 14-month period, 1414 patients underwent PD without (82.2%) or with major venous (PD + V; 13.7%) or arterial (PD + A; 4.0%) vascular resection. RESULTS: Postoperative morbidity and mortality following PD + A (51.0% and 3.6%) was comparable to PD + V (46.9% and 3.6%) and PD (44.3 and 1.5%, p = 0.50 and 0.43). A propensity score matched analysis revealed that vascular resection was associated with significant increases (p ≤ 0.05) in operative time (7:37 vs 6:11), need for blood transfusion (42.2% vs 18.1%), deep venous thromboembolism (6.9% vs 0.9%), postoperative septic shock (6.9% vs 1.7%), and length of stay (12.2 vs 10 days) while overall morbidity (45.7% vs 46.6) and mortality (1.0% vs 0%) were comparable. CONCLUSIONS: Compared to PD alone, PD + VR was associated with increased operative time, perioperative transfusions, deep venous thrombosis, septic shock, as well as length of stay, but overall morbidity and mortality were not increased.

Relative Contributions of Complications and Failure to Rescue on Mortality in Older Patients Undergoing Pancreatectomy.

BACKGROUND: For pancreatectomy patients, mortality increases with increasing age. Our study evaluated the relative contribution of overall postoperative complications and failure to rescue rates on the observed increased mortality in older patients undergoing pancreatic resection at specialized centers. METHODS: We identified 2694 patients who underwent pancreatic resection from the American College of Surgeons' National Surgical Quality Improvement Pancreatectomy Demonstration Project at 37 high-volume centers. Overall morbidity and in-hospital mortality were determined in patients younger than 80 years (N = 2496) and 80 years or older (N = 198). Failure to rescue was the number of deaths in patients with complications divided by the total number of patients with postoperative complications. RESULTS: No significant differences were observed between patients younger than 80 years and those 80 years or older in the rates of overall complications (41.4% vs 39.4%, P = 0.58). In-hospital mortality increased in patients 80 years or older compared to patients younger than 80 years (3.0% vs 1.1%, P = 0.02). Failures to rescue rates were higher in patients 80 years or older (7.7% vs 2.7%, P = 0.01). Across 37 high-volume centers, unadjusted complication rates ranged from 25.0% to 72.2% and failure to rescue rates ranged from 0.0% to 25.0%. Among patients with postoperative complications, comorbidities associated with failure to rescue were ascites, chronic obstructive pulmonary disease, and diabetes. Complications associated with failure to rescue included acute renal failure, septic shock, and postoperative pulmonary complications. CONCLUSIONS: In experienced hands, the rates of complications after pancreatectomy in patients 80 years or older compared to patients younger than 80 years were similar. However, when complications occurred, older patients were more likely to die. Interventions to identify and aggressively treat complications are necessary to decrease mortality in vulnerable older patients.
