RESUMO

PURPOSE: To evaluate and compare the nutritional factors and clinical outcomes of pancreaticoduodenectomy between elderly and non-elderly patients. METHODS: This retrospective study evaluated 122 consecutive patients who underwent pancreaticoduodenectomy from April 2008 to April 2020. Preoperative and postoperative nutritional factors (prognostic nutritional index), complication rates, and survival rates were compared between the elderly (≥ 80 years) and non-elderly (< 80 years) patient groups. Changes in nutrition markers were evaluated before surgery to 1 year after surgery. RESULTS: A total of 20 elderly patients (16.4%) and 102 non-elderly patients (83.6%) underwent pancreaticoduodenectomy. Elderly patients had a significantly lower preoperative prognostic nutritional index than did non-elderly patients. At 3 months postoperatively, elderly patients had a lower albumin level and prognostic nutritional index. The median length of hospital stay was significantly longer (39.9 vs. 27 days, P = 0.004), the rate of death due to other diseases was higher, and the overall survival rate was significantly lower (1-/3-/5 year overall survival rates: 78.1%/26.7%/13.3% vs. 87.1%/54.4%/46.7%; log-rank test, P = 0.003) in the elderly group than in the non-elderly group. CONCLUSIONS: The results suggest that careful patient selection and optimal perioperative care are necessary to determine whether pancreaticoduodenectomy is indicated for elderly patients.

RESUMO

La operación de Whipple es el procedimiento quirúrgico de mayor complejidad en cirugía abdominal, este se realiza en pacientes con tumores de la encrucijada pancreatoduodenal, es la única alternativa para tratamiento curativo en fases tempranas de la enfermedad. Objetivo: Determinar los resultados del procedimiento Whipple, en pacientes intervenidos con tumores de la encrucijada pancreatoduodenal en el Hospital General de Enfermedades del Instituto Guatemalteco de Seguridad Social, en el periodo de enero 2,015 a enero 2,020. Método: Descriptivo, observacional, retrospectivo. Resultados: Se incluyeron 42 procedimientos de Whipple, 29 (69%) casos del género masculino y 13 (31%) para el género femenino. La edad media fue de 61.5 años, el 54% presentaban comorbilidad asociada. El 24% utilizo transfusión transoperatoria de hemoderivados, el tiempo quirúrgico de 5.5 horas. La reintervención fue del 4.7%. Complicaciones postoperatorias tempranas 18%. La histología más común fue el carcinoma de cabeza de páncreas en el 43%. La mortalidad postoperatoria temprana fue del 4.7%. El OR de complicaciones asociadas a comorbilidades fue de 1.7 con un IC 0.3046-7.20 y un valor de P: 0.9251 que no es estadísticamente significativo. Conclusiones: Los tumores pancreatoduodenales en nuestra población se presentan en edades más tempranas a lo reportado. La morbimortalidad es similar a lo reportado en otros estudios a nivel latinoamericano, sin embargo las complicaciones están más elevadas que las mejores series internacionales. No existe asociación entre el riesgo de complicaciones con comorbilidades del paciente. (AU)

RESUMO

BACKGROUND AND AIMS: The effect of operation volume on the outcomes of pancreatic surgery has been a subject of research since the 1990s. In several countries around the world, this has led to the centralization of pancreatic surgery. However, controversy persists as to the benefits of centralization and what the optimal operation volume for pancreatic surgery actually is. This review summarizes the data on the effect of centralization on mortality, complications, hospital facilities used, and costs regarding pancreatic surgery. MATERIALS AND METHODS: A systematic librarian-assisted search was performed in PubMed covering the years from August 1999 to August 2019. All studies comparing results of open pancreatic resections from high- and low-volume centers were included. In total 44, published articles were analyzed. RESULTS: Studies used a variety of different criteria for high-volume and low-volume centers, which hampers the evaluating of the effect of operation volume. However, mortality in high-volume centers is consistently reported to be lower than in low-volume centers. In addition, failure to rescue critically ill patients is more common in low-volume centers. Cost-effectiveness has also been evaluated in the literature. Length of hospital stay in particular has been reported to be shorter in high-volume centers than in low-volume centers. CONCLUSION: The effect of centralization on the outcomes of pancreatic surgery has been under active research and the beneficial effect of it is associated especially with better short-term prognosis after surgery.

RESUMO

BACKGROUND: High hospital-volume and service capability are associated with improved mortality following complex cancer surgery. Using a population-based study in Queensland, we assessed differences in mortality following oesophagectomy and pancreaticoduodenectomy, comparing high- and low-volume hospitals stratified by service capability. METHODS: Data on all patients undergoing oesophagectomy and pancreaticoduodenectomy for cancer in Queensland between 2001 and 2015 were obtained from the Queensland Oncology Repository. Hospital service capability was defined using the 2015 Australian Institute of Health and Welfare hospital peer groupings. Hospitals were grouped into 'high-volume (≥6 oesophagectomies or pancreaticoduodenectomies annually) with high service capability'; 'low-volume (<6) with high service capability' and 'low-volume with low service capability'. Multivariate Poisson models were used to estimate differences in 30- and 90-day mortality between hospital groups adjusting for age, sex, socioeconomic status, Charlson and American Society of Anesthesiologists scores, chemotherapy, radiotherapy, stage and time-period. RESULTS: For oesophagectomy, adjusted 90-day mortality was higher in low-volume compared with high-volume hospitals, regardless of service capability (low-volume, high service: incident rate ratio (IRR) 3.86, 95% confidence interval (CI) 1.74-8.57; low-volume, low service: IRR 3.40, 95% CI 1.16-10.00). For pancreaticoduodenectomy, mortality was higher in low-volume compared with high-volume centres regardless of service capability: 30-day mortality (low-volume, high service: IRR 2.32, 95% CI 1.07-5.03; low-volume, low service: IRR 3.92, 95% CI 1.45-10.61); 90-day mortality (low-volume, high service: IRR 2.36, 95% CI 1.29-4.30; low-volume, low service: IRR 3.32, 95% CI 1.64-6.71). CONCLUSION: High hospital resection volumes are associated with lower post-operative mortality following oesophagectomy and pancreaticoduodenectomy regardless of hospital service capability. This data supports centralization of these procedures to high-volume centres.

RESUMO

BACKGROUND: It is not known whether the treatment costs of pancreatic surgery can be reduced by centralisation. The aim of this study was to analyse the impact of hospital volume on the short-term prognosis and costs in a nationwide study. METHODS: The National registry was searched for patients undergoing pancreatoduodenectomy (PD) in Finland between 2012 and 2014. Patient data was recorded up to ninety days postoperatively and Charlson comorbidity index (CCI) calculated. Complications were classified according to Clavien-Dindo. A CCI was calculated for each patient. The hospitals were categorized by yearly resection rate: high (≥20, HVC), medium (6-19, MVC) and low (≤5, LVC). Costs were calculated according to the 2012 billing list. RESULTS: The study population comprised 466 patients. Demographics were similar in the HVC, MVC and LVC groups. Mortality was lower in the HVCs than in MVCs and LVCs at 30 days (0.8% vs. 8.8-12.9%; p < 0.01) and at 90 days (1.9% vs. 10.5-16.1%; p < 0.01). Hospital volume and CCI were significant factors for mortality in multivariate analysis. Median costs among all patients were lower in the HVC group than in the MVC/LVC groups (p = 0.019), among Clavien-Dindo class III (0.020), among patients over 75 years (p < 0.001) and among patients who survived over five days (p = 0.015). CONCLUSIONS: Thirty- and 90-day mortality is 10 times lower when the patient is operated on in an HVC. The study shows that the median overall costs of surgical treatment are 82-88% of the median costs in lower volume centres.

RESUMO

BACKGROUND: We sought to determine treatment outcomes after pancreatoduodenectomy for pancreatic head and uncinate process malignancy and its impact on mortality, morbidity, and resource utilization. METHODS: This was a retrospective cohort study using the 2014 Nationwide Readmissions Database. Discharges were included if they had an ICD-9 CM procedure code for pancreatoduodenectomy and any code for malignancy of the pancreas head and uncinate process. Independent predictors of readmission were identified using multivariable Cox regression analysis. RESULTS: A total of 4,445 patients were included. The surgical complication rate was 17.3%, and in-hospital mortality rate was 3%. The 30-day readmission rate was 19.7% with an in-hospital mortality rate of 3.9%. The most common reason for readmission was postoperative infection. The mean length of stay during readmission was 6.50 days, while the mean total hospitalization costs and charges were $15,589 and $52,922, respectively. The number of hospital days associated with readmission was 5,548, with an in-hospital economic burden of $12.9 million (costs) and $43.7 million (charges). Hospital volume and discharge disposition were independent predictors of 30-day readmission. CONCLUSIONS: Pancreatoduodenectomy for pancreatic malignancies is still associated with significant morbidity, mortality and 30-day readmission. Reducing readmission can impact mortality, quality of life, and healthcare economic burden in this setting.

RESUMO

BACKGROUND: Few studies investigated biliary leakage after pancreaticoduodenectomy (PD) especially when compared to postoperative pancreatic fistula (POPF). This study was to determine the incidence of biliary leakage after PD, predisposing factors of biliary leakage, and its management. METHODS: We retrospectively studied all patients who underwent PD from January 2008 to December 2017 at Gastrointestinal Surgery Center, Mansoura University, Egypt. According to occurrence of postoperative biliary leakage, patients were divided into two groups. Group (1) included patients who developed biliary leakage and group (2) included patients without identified biliary leakage. The preoperative data, operative details, and postoperative morbidity and mortality were analyzed. RESULTS: The study included 555 patients. Forty-four patients (7.9%) developed biliary leakage. Ten patients (1.8%) had concomitant POPF. Multivariate analysis identified obesity and time needed for hepaticojejunostomy reconstruction as independent risk factors of biliary leakage, and no history of preoperative endoscopic retrograde cholangiopancreatiography (ERCP) as protective factor. Biliary leakage from hepaticojejunostomy after PD leads to a significant increase in development of delayed gastric emptying, and wound infection. The median hospital stay and time to resume oral intake were significantly greater in the biliary leakage group. Non-surgical management was needed in 40 patients (90.9%). Only 4 patients (9.1%) required re-exploration due to biliary peritonitis and associated POPF. The mortality rate in the biliary leakage group was significantly higher than that of the non-biliary leakage group (6.8% vs 3.9%, P = 0.05). CONCLUSIONS: Obesity and time needed for hepaticojejunostomy reconstruction are independent risk factors of biliary leakage, and no history of preoperative ERCP is protective factor. Biliary leakage increases the risk of morbidity and mortality especially if concomitant with POPF. However, biliary leakage can be conservatively managed in majority of cases.

RESUMO

BACKGROUND: Currently, surgical resection represents the only curative treatment for pancreatic cancer (PC), however, the majority of tumors are no longer resectable by the time of diagnosis. The aim of this study was to describe time trends and distribution of pancreaticoduodenectomies (PDs) performed for treating PC in Brazil in recent years. METHODS: Data were retrospectively obtained from Brazilian Health Public System (namely DATASUS) regarding hospitalizations for PC and PD in Brazil from January 2008 to December 2015. PC and PD rates and their mortalities were estimated from DATASUS hospitalizations and analyzed for age, gender and demographic characteristics. RESULTS: A total of 2364 PDs were retrieved. Albeit PC incidence more than doubled, the number of PDs increased only 37%. Most PDs were performed in men (52.2%) and patients between 50 and 69 years old (59.5%). Patients not surgically treated and those 70 years or older had the highest in-hospital mortality rates. The most developed regions (Southeast and South) as well as large metropolitan integrated municipalities registered 76.2% and 54.8% of the procedures, respectively. LMIM PD mortality fluctuated, ranging from 13.6% in 2008 to 11.8% in 2015. CONCLUSIONS: This study suggests a trend towards regionalization and volume-outcome relationships for PD due to PC, as large metropolitan integrated municipalities registered most of the PDs and more stable mortality rates. The substantial differences between PD and PC increasing rates reveals a limiting step on the health system resoluteness. Reduction in the number of hospital beds and late access to hospitalization, despite improvement in diagnostic methods, could at least in part explain these findings.

RESUMO

BACKGROUND: Complications frequently occur after pancreaticoduodenectomy. Patients undergoing pancreaticoduodenectomy tend to be older; age and postoperative complication may be associated. To clarify this association, we compared postoperative outcomes in patients undergoing pancreaticoduodenectomy based on age group. We aimed to determine whether we could identify an age cutoff where the incidence and cost of postoperative complications starts increasing and potentially outweigh the potential benefits of pancreaticoduodenectomy. MATERIALS AND METHODS: We built a retrospective cohort of consecutive patients undergoing pancreaticoduodenectomy at one institution from 2011 to 2017. Demographics, operative data and costs were obtained from hospital and administrative databases. A restricted cubic spline regression analysis was performed to graphically identify the age in which the comprehensive complication index (CCI) substantially increased. Cost analysis was undertaken from the perspective of a third-party payer. Differences in costs between age groups were tested using t-test. RESULTS: Among 440 patients, the CCI became significantly higher at the age cutoff of 72 (median 21 in the older vs. 12 in the younger group, P = 0.014). Postoperative complications (74% vs. 64%, P = 0.038), and mortality (8% vs. 3%, P = 0.016) were also significantly higher in the older age group; mostly driven by pneumonia (11% vs. 6%, P = 0.097), myocardial infarction (12% vs. 4%, P < 0.002) and urinary tract infection (18% vs. 5%, P = 0.003). Median length of hospital stay was also longer for the older age group (10 vs. 8 days, P = 0.002). Total mean cost was significantly higher in the older age group ($38,225 CAD vs. $29,771 CAD). CONCLUSIONS: In our cohort of patients, after age 72, pancreaticoduodenectomy is associated with significantly more postoperative complications and deaths which translated in longer hospital stay and higher costs. This information may help patients and surgeons make informed decisions.

RESUMO

BACKGROUND: An initiative was established to improve value-based care for pancreatic surgery in a large nonprofit health system. Cost data were presented bimonthly to a hepatobiliary clinical performance group via videoconference. STUDY DESIGN: The direct costs were calculated for all patients undergoing distal pancreatectomy (DP) and pancreaticoduodenectomy (PD) between January 2014 and July 2017. Median length of stay, 30-day and 90-day mortality rates, readmission rate, and costs were stratified by surgeon volume using 2 published criteria: "volume pledge" criteria (≥5 PDs/year) and Leapfrog criteria (≥11 PDs/year). RESULTS: There were 270 DPs and 526 PDs performed in 14 hospitals spanning 4 states. Median PD costs were lower for high-volume surgeons (≥5 PDs/year), $21,026 vs $24,706 (p = 0.005). High-volume surgeons had a shorter length of stay (9 days vs 11 days; p < 0.001) for PD and DP (6 days vs 7 days; p = 0.001). Increased costs for low-volume surgeons included operative/anesthesia costs ($7,321 vs $6,325; p = 0.03), room and board ($5,828 vs $4,580; p = 0.01), and intensive care costs ($4,464 vs $3,113; p = 0.04). Operating time was increased for high-volume surgeons for DP and PD (p < 0.001). There was no difference in 30-day or 90-day mortality rates or readmissions for DP or PD when stratified by volume pledge criteria. There was no difference in total costs for DP or PD when stratified by Leapfrog criteria. CONCLUSIONS: There was a significant cost reduction for PD but not DP when the threshold of 5 PDs was used as a definition of high volume. The sharing of detailed financial data with HPB surgeons on a regular basis provides an opportunity to evaluate practice patterns and thereby reduce direct costs.

RESUMO

OBJECTIVE: Measure the caseload of pancreatectomies that influences their short-term outcome, at a national level, and assess the applicability of a centralization policy. BACKGROUND: There is agreement that pancreatectomies should be centralized. However, previous studies have failed to accurately define a "high-volume" center. METHODS: French healthcare databases were screened to identify all adult patients who had elective pancreatectomies between 2007 and 2012. The patients' age, comorbidities, indication, and extent of surgery, and also the hospital administrative-type and location were retrieved. The annual-caseload of pancreatectomy was calculated for each hospital facility. The primary endpoint was 90-day mortality. Spline modeling was used to identify the different annual-caseload that influenced mortality. Logistic regressions were performed to assess if their influence was independent of confounders, and the accuracy of the model calculated. RESULTS: Overall, 22,366 patients underwent a pancreatectomy and the mortality was 8.1%. Two cut-offs were identified (25 and 65 per year): compared with centers performing >65 resections per year, the adjusted OR of mortality was 1.865 (1.529-2.276) in centers performing ≤25 resections per year and 1.234 (1.031-1.478) in those performing 26 to 65 resections per year. The average number of facilities performing ≤25, 26 to 65, and >65 pancreatectomies per year was 456, 20, and 9, respectively. The percentage of patients operated in these facilities was 56.6%, 19.9%, and 23.3%, respectively.For pancreaticoduodenectomies (12,670 patients; mortality 9.2%), there were 2 cut-offs (16 and 40 pancreaticoduodenectomies per year), and both were independent predictors of mortality (adjusted OR of 1.979 and 1.333). For distal pancreatectomies (7085 patients; 6.2% mortality), there were 2 cut-offs (13 and 25 distal pancreatectomies per year), but neither was an independent predictor of outcome (area under the receiver-operating characteristic curve of the model = 0.778). CONCLUSIONS: Centralization of pancreatic surgery is theoretically justified, but currently unrealizable. As the incidence of pancreatic cancer increases, there is an urgent need to improve the training of surgeons and develop both intermediate and high-volume centers.

RESUMO

INTRODUCTION: The benefit of portal-superior mesenteric vein resection (PSMVR) with pancreatoduodenectomy (PD) remains controversial. This study assesses the impact of PSMVR on resection margin status and survival. METHOD: An electronic search was performed to identify relevant articles. Pooled odds ratios were calculated for outcomes using the fixed or random-effects models for meta-analysis. A decision analytical model was developed for estimating cost effectiveness. RESULTS: Sixteen studies with 4145 patients who underwent pancreatoduodenectomy were included: 1207 patients had PSMVR and 2938 patients had no PSMVR. The R1 resection rate and post-operative mortality was significantly higher in PSMVR group (OR1.59[1.35, 1.86] p=<0.0001, and OR1.72 [1.02,2.92] p = 0.04 respectively). The overall survival at 5-years was worse in the PSMVR group (HR0.20 [0.07,0.55] P = 0.020). Tumour size (p = 0.030) and perineural invasion (P = 0.009) were higher in the PSMVR group. Not performing PSMVR yielded cost savings of $1617 per additional month alive without reduction in overall outcome. CONCLUSION: On the basis of retrospective data this study shows that PD with PSMVR is associated with a higher R1 rate, lower 5-year survival and is not cost-effective. It appears that PD with PSMVR can only be justified if R0 resection can be achieved. The continuing challenge is accurate selection of these patients.

RESUMO

BACKGROUND: There is an increasing needed to consider pancreaticoduodenectomy (PD) for the treatment of pancreatic and periampullary malignancy in patients aged 80 and over, given the increasing aging population. METHODS: A systematic literature search was undertaken to identify selected studies that compared the outcomes of patients aged 80 years or over to those younger undergoing PD. RESULTS: In total 18 studies were included for evaluation. Octogenarian or older populations had significantly higher 30-day post-operative mortality rate (OR: 2.22, 95% CI = 1.48-3.31, p < 0.001) and length of hospital stay (OR: 2.23, 95% CI = 1.36-3.10, p < 0.001). The overall post-operative complication rate was higher in the older group compared to the younger population (OR: 1.51, 95% CI = 1.25-1.83, p < 0.001). Elderly patients were more likely to develop pneumonia (OR: 1.72, 95% CI = 1.39-2.13, p < 0.001) and experience delayed gastric emptying (DGE) (OR: 1.77, 95% CI = 1.35-2.31, p < 0.001). The incidence of post-operative pancreatic fistula and bile leak were not significantly different between the groups. Rehabilitation and home nursing care services was also more frequently required by the older patient group at the time of hospital discharge. CONCLUSION: Patients aged 80 years and older have approximately double the risk of 30-day post-operative mortality and 50% increased rate of complications following PD. Careful patient selection is required when offering surgery in this age group.

RESUMO

BACKGROUND: Participation by surgical trainees in complex procedures is key to their development as future practicing surgeons. The impact of surgical fellows versus general surgery resident assistance on outcomes in pancreatoduodenectomy (PD) has not been well studied. The purpose of this study was to determine differences in patient outcomes based on level of surgical trainee. METHODS: Consecutive cases of PD (n = 254) were reviewed at a single high-volume institution over a 2-year period (July 2013-June 2015). Thirty-day outcomes were monitored through the American College of Surgeon's National Surgical Quality Improvement Program (NSQIP) and Quality In-Training Initiative. Patient outcomes were compared between PD assisted by general surgery residents versus hepatopancreatobiliary fellows. RESULTS: The hepatopancreatobiliary surgery fellows and general surgery residents participated in 109 and 145 PDs, respectively. The incidence of each individual postoperative complication (renal, infectious, pancreatectomy-specific, and cardiopulmonary), total morbidity, mortality, and failure to rescue were the same between groups. CONCLUSIONS: Patient operative outcomes were the same between fellow- and resident-assisted PD. These results suggest that hepatopancreatobiliary surgery fellows and general surgery residents should be offered the same opportunities to participate in complex general surgery procedures.

RESUMO

Surgical resection offers the only prospect of cure in pancreatic cancer patients. The probability of undergoing surgery is determined by several factors. The influence of socio-economic status (SES) on surgical treatment and survival was investigated in the Netherlands, a country with a widely accessible healthcare system. METHODS: Data on all patients with non-metastasised pancreatic cancer between 2005-2013 were analysed in the Eindhoven Cancer Registry (ECR). SES was categorized as low, intermediate or high. The influence of SES on the likelihood for surgery was assessed by multivariable logistic regression analyses. The influence on overall survival was analysed by multivariable Cox regression analyses. RESULTS: 698 M0-patients were included, of whom 276 underwent surgery. Patients with low and intermediate SES were less likely to undergo surgery (32% vs 37%) than high-SES patients (48%) (p = 0.002; low SES: OR0.63, 95%CI [0.40-0.98]; intermediate SES: OR0.62, 95%CI [0.42-0.92]). Survival did not differ between SES groups (low SES: HR1.05 95%CI [0.85-1.30]; intermediate SES: HR1.11, 95%CI [0.91-1.35]), p = 0.181. SES in pancreatic cancer patients determined the likelihood for surgery. However, SES had no influence on survival. It is important to provide more insights in the causes of these inequalities to minimalize the effects of SES in pancreatic cancer care.

RESUMO

BACKGROUND: We aimed to examine the burden of intrahepatic cholangiocarcinoma (ICC) in Thailand and identify the prognostic factors for all-causes of death. METHODS: We conducted a population-based study of ICC patients admitted during 2009-2013 using the Nationwide Hospital Admission Database, the National Health Security Office (NHSO). There was an average of 1,051,146 patients/year with diagnosis of gastrointestinal diseases (GI). All patients with a diagnosis of ICC (ICD10- C221) were included from a total of 72,479 admissions from 858 hospitals. The surgical resection procedures such as the radical pancreaticoduodenectomy, subtotal and partial hepatectomy were analyzed. Data for all patients were censored 1 year post-study or death, whichever came first. RESULTS: A total of 34,325 patients with ICC during a 5-year study period (on average, 6865 patients/year, with the incidence rate of 14.6 per 100,000 population, per year. The ICC patients had a mean age of 63.8+/-11.6 years and 63% were males. The mean length of hospital stay was 6.4+/-7.3 days with a mean+/-SD cost of hospitalization of $595+/-$1160 USD per admission. There were 659 patients (1.9%) underwent surgical resection. The overall survival of ICC patients with surgery was significantly better than those patients without surgery. Hazard ratio of death for patients without surgery was 2.5 (95% CI of 2.3-2.7). Approximately 14% of the ICC patients died during hospitalization. The median overall survival of all patients after the first admission was 53 +/-0.6 days. From the multivariate analysis, factors related to all-causes of death were: patients' age >60 years (OR = 1.2, 95% CI; 1.1-1.3), length of hospital stay of >7 days (OR = 1.1, 95% CI; 1.02-1.2), male (OR = 1.3, 95% CI; 1.2-1.4), living in the northern part of Thailand (OR = 1.5, 95% CI; 1.3-1.8) and presence of complications during admission (OR = 1.3, 95% CI; 1.1-1.5). CONCLUSION: The disease burden of patients with ICC in Thailand is significant with the incidence rate of 14.6 per 100,000 population, per year during 2009-2013 and showed high mortality rate of 14%.

RESUMO

BACKGROUND: As payment models evolve, disease-specific risk stratification may impact patient selection and financial outcomes. This study sought to determine whether a validated clinical risk score for post-operative pancreatic fistula (POPF) could predict hospital costs, payments, and profit margins. METHODS: A multi-institutional cohort of 1193 patients undergoing pancreaticoduodenectomy (PD) were matched to an independent hospital where cost, in US$, and payment data existed. An analytic model detailed POPF risk and post-operative sequelae, and their relationship with hospital cost and payment. RESULTS: Per-patient hospital cost for negligible-risk patients was $37,855. Low-, moderate-, and high- risk patients had incrementally higher hospital costs of $38,125 ($270; 0.7% above negligible-risk), $41,128 ($3273; +8.6%), and $41,983 ($3858; +10.9%), respectively. Similarly, hospital payment for negligible-risk patients was $42,685/patient, with incrementally higher payments for low-risk ($43,265; +1.4%), moderate-risk ($45,439; +6.5%) and high-risk ($46,564; +9.1%) patients. The lowest 30-day readmission rates - with highest net profit - were found for negligible/low-risk patients (10.5%/11.1%), respectively, compared with readmission rates of moderate/high-risk patients (15%/15.7%). CONCLUSION: Financial outcomes following PD can be predicted using the FRS. Such prediction may help hospitals and payers plan for resource allocation and payment matched to patient risk, while providing a benchmark for quality improvement initiatives.

RESUMO

BACKGROUND: Older patients are increasingly faced with pancreatic surgery because of shifting demographics. The differential effects of aging on surgical outcomes remain vague, while the elderly patient is often neglected in clinical trials. METHODS: Medical records of 370 patients who underwent pancreaticoduodenectomy were analyzed. Patients were then subdivided into 3 groups according to age and comorbidities. RESULTS: Overall mortality was 5% and did not significantly differ between age-matched groups. Increasing age was linked to a higher prevalence of diabetes mellitus (p < 0.001) and preoperative cardiovascular comorbidities (p < 0.001). Independent risk factors for major complications were age over 70 years (p = 0.018; OR 2.3), elevated body mass index (p = 0.004; OR 0.2) and cardiovascular comorbidities (p = 0.022; OR = 2.6). Patients who were older (>70 years), obese and had cardiovascular disease had an increased risk of major complications when compared with the younger study population (p = 0.010). CONCLUSIONS: Pancreatic surgery in elderly patients showed similar mortality rates as in younger patients. Nevertheless, a careful risk assessment is particularly important because older patients who are considered to be high risk suffer more frequently from major surgical complications compared with young patients that have similar risk profiles.

RESUMO

BACKGROUND: According to current guidelines, pancreatic cancer patients should be strictly selected for surgery, either palliative or resective. METHODS: Population-based study, including all patients undergoing surgery for pancreatic cancer in Italy between 2010 and 2012. Hospitals were divided into five volume groups (quintiles), to search for differences among volume categories. RESULTS: There were 544 hospitals performing 10 936 pancreatic cancer operations. The probability of undergoing palliative/explorative surgery was inversely related to volume, being 24.4% in very high-volume hospitals and 62.5% in very low-volume centres (adjusted OR 5.175). Contrarily, the resection rate in patients without metastases decreased from 86.9% to 46.1% (adjusted OR 7.429). As for resections, the mortality of non-resective surgery was inversely related to volume (p < 0.001). Surprisingly, mortality of non-resective surgery was higher than that for resections (8.2% vs. 6.7%; p < 0.01). Approximately 9% of all resections were performed on patients with distant metastases, irrespective of hospital volume group. The excess cost for the National Health System from surgery overuse was estimated at 12.5 million euro. DISCUSSION: Discrepancies between guidelines on pancreatic cancer treatment and surgical practice were observed. An overuse of surgery was detected, with serious clinical and economic consequences.

RESUMO

BACKGROUND: Management of cystic lesions of the pancreas (CLP) is controversial. In this study, we sought to evaluate national changes in the resection of CLP over time, to better understand the impact of evolving guidelines on CLP management. METHODS: We used Medicare data to examine CLP resection among patients undergoing pancreatic resection between 2001 and 2012. Patients with a diagnosis of CLP were identified and compared to patients with non-CLP indications. We then examined changes over time in patient and hospital characteristics and outcomes among patients with a CLP diagnosis. RESULTS: We identified 56,419 Medicare patients undergoing pancreatic resection, of which 2129 had a CLP diagnosis. The annual number of CLP resections, and proportion of all resections performed for CLP increased significantly during the period, from 2.1% (65/3072) resections in 2001, to 4.5% (286/6348) in 2012 (p < 0.001). The proportion of CLP resections with a malignant diagnosis did not change (15.5% in 2001-2003 vs. 13.1% in 2010-2012, p = 0.4). Overall rates of 30-day mortality decreased significantly during the period (9.6% in 2001-2003 vs. 5.5% in 2010-2012, p < 0.001). DISCUSSION: CLP resections were performed with increasing frequency in Medicare patients between 2001 and 2012, but this did not correspond to increased diagnosis of malignancy. Additional research is needed to understand the influence of recent guidelines on management of CLP.
