RESUMEN
BACKGROUND: Diabetes mellitus (DM) has a complex relationship with pancreatic cancer. This study examines the impact of preoperative DM, both recent-onset and pre-existing, on long-term outcomes following pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). METHODS: Data were extracted from the Recurrence After Whipple's (RAW) study, a multi-centre cohort of PD for pancreatic head malignancy (2012-2015). Recurrence and five-year survival rates of patients with DM were compared to those without, and subgroup analysis performed to compare patients with recent-onset DM (less than one year) to patients with established DM. RESULTS: Out of 758 patients included, 187 (24.7%) had DM, of whom, 47 of the 187 (25.1%) had recent-onset DM. There was no difference in the rate of postoperative pancreatic fistula (DM: 5.9% vs no DM 9.8%; p = 0.11), five-year survival (DM: 24.1% vs no DM: 22.9%; p = 0.77) or five-year recurrence (DM: 71.7% vs no DM: 67.4%; p = 0.32). There was also no difference between patients with recent-onset DM and patients with established DM in postoperative outcomes, recurrence, or survival. CONCLUSION: We found no difference in five-year recurrence and survival between diabetic patients and those without diabetes. Patients with pre-existing DM should be evaluated for PD on a comparable basis to non-diabetic patients.

Backgrounds/Aims: After pancreatoduodenectomy (PD), an early oral diet is recommended; however, the postoperative nutritional management of PD patients is known to be highly variable, with some centers still routinely providing parenteral nutrition (PN). Some patients who receive PN experience clinically significant complications, underscoring its judicious use. Using a large cohort, this study aimed to determine the proportion of PD patients who received postoperative nutritional support (NS), describe the nature of this support, and investigate whether receiving PN correlated with adverse perioperative outcomes. Methods: Data were extracted from the Recurrence After Whipple's study, a retrospective multicenter study of PD outcomes. Results: In total, 1,323 patients (89%) had data on their postoperative NS status available. Of these, 45% received postoperative NS, which was "enteral only," "parenteral only," and "enteral and parenteral" in 44%, 35%, and 21% of cases, respectively. Body mass index < 18.5 kg/m2 (p = 0.03), absence of preoperative biliary stenting (p = 0.009), and serum albumin < 36 g/L (p = 0.009) all correlated with receiving postoperative NS. Among those who did not develop a serious postoperative complication, i.e., those who had a relatively uneventful recovery, 20% received PN. Conclusions: A considerable number of patients who had an uneventful recovery received PN. PN is not without risk, and should be reserved for those who are unable to take an oral diet. PD patients should undergo pre- and postoperative assessment by nutrition professionals to ensure they are managed appropriately, and to optimize perioperative outcomes.
RESUMEN
BACKGROUND: Pancreatoduodenectomy (PD) is associated with significant postoperative morbidity. Surgeons should have a sound understanding of the potential complications for consenting and benchmarking purposes. Furthermore, preoperative identification of high-risk patients can guide patient selection and potentially allow for targeted prehabilitation and/or individualized treatment regimens. Using a large multicentre cohort, this study aimed to calculate the incidence of all PD complications and identify risk factors. METHOD: Data were extracted from the Recurrence After Whipple's (RAW) study, a retrospective cohort study of PD outcomes (29 centres from 8 countries, 2012-2015). The incidence and severity of all complications was recorded and potential risk factors for morbidity, major morbidity (Clavien-Dindo grade > IIIa), postoperative pancreatic fistula (POPF), post-pancreatectomy haemorrhage (PPH) and 90-day mortality were investigated. RESULTS: Among the 1348 included patients, overall morbidity, major morbidity, POPF, PPH and perioperative death affected 53 per cent (n = 720), 17 per cent (n = 228), 8 per cent (n = 108), 6 per cent (n = 84) and 4 per cent (n = 53), respectively. Following multivariable tests, a high BMI (P = 0.007), an ASA grade > II (P < 0.0001) and a classic Whipple approach (P = 0.005) were all associated with increased overall morbidity. In addition, ASA grade > II patients were at increased risk of major morbidity (P < 0.0001), and a raised BMI correlated with a greater risk of POPF (P = 0.001). CONCLUSION: In this multicentre study of PD outcomes, an ASA grade > II was a risk factor for major morbidity and a high BMI was a risk factor for POPF. Patients who are preoperatively identified to be high risk may benefit from targeted prehabilitation or individualized treatment regimens.

Backgrounds/Aims: Pancreatoduodenectomy (PD) is recommended in fit patients with a carcinoma (PDAC) of the pancreatic head, and a delayed resection may affect survival. This study aimed to correlate the time from staging to PD with long-term survival, and study the impact of preoperative investigations (if any) on the timing of surgery. Methods: Data were extracted from the Recurrence After Whipple's (RAW) study, a multicentre retrospective study of PD outcomes. Only PDAC patients who underwent an upfront resection were included. Patients who received neoadjuvant chemo-/radiotherapy were excluded. Group A (PD within 28 days of most recent preoperative computed tomography [CT]) was compared to group B (> 28 days). Results: A total of 595 patents were included. Compared to group A (median CT-PD time: 12.5 days, interquartile range: 6-21), group B (49 days, 39-64.5) had similar one-year survival (73% vs. 75%, p = 0.6), five-year survival (23% vs. 21%, p = 0.6) and median time-todeath (17 vs. 18 months, p = 0.8). Staging laparoscopy (43 vs. 29.5 days, p = 0.009) and preoperative biliary stenting (39 vs. 20 days, p < 0.001) were associated with a delay to PD, but magnetic resonance imaging (32 vs. 32 days, p = 0.5), positron emission tomography (40 vs. 31 days, p > 0.99) and endoscopic ultrasonography (28 vs. 32 days, p > 0.99) were not. Conclusions: Although a treatment delay may give rise to patient anxiety, our findings would suggest this does not correlate with worse survival. A delay may be necessary to obtain further information and minimize the number of PD patients diagnosed with early disease recurrence.
RESUMEN
INTRODUCTION: Adjuvant chemotherapy (AC) can prolong overall survival (OS) after pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). However, fitness for AC may be influenced by postoperative recovery. We aimed to investigate if serious (Clavien-Dindo grade ≥ IIIa) postoperative complications affected AC rates, disease recurrence and OS. MATERIALS AND METHODS: Data were extracted from the Recurrence After Whipple's (RAW) study (n = 1484), a retrospective study of PD outcomes (29 centres from eight countries). Patients who died within 90-days of PD were excluded. The Kaplan-Meier method was used to compare OS in those receiving or not receiving AC, and those with and without serious postoperative complications. The groups were then compared using univariable and multivariable tests. RESULTS: Patients who commenced AC (vs no AC) had improved OS (median difference: (MD): 201 days), as did those who completed their planned course of AC (MD: 291 days, p < 0.0001). Those who commenced AC were younger (mean difference: 2.7 years, p = 0.0002), more often (preoperative) American Society of Anesthesiologists (ASA) grade I-II (74% vs 63%, p = 0.004) and had less often experienced a serious postoperative complication (10% vs 18%, p = 0.002). Patients who developed a serious postoperative complication were less often ASA grade I-II (52% vs 73%, p = 0.0004) and less often commenced AC (58% vs 74%, p = 0.002). CONCLUSION: In our multicentre study of PD outcomes, PDAC patients who received AC had improved OS, and those who experienced a serious postoperative complication commenced AC less frequently. Selected high-risk patients may benefit from targeted preoperative optimisation and/or neoadjuvant chemotherapy.

BACKGROUND: Pancreatoduodenectomy (PD) is recommended in fit patients with a resectable ampullary adenocarcinoma (AA). We aimed to identify predictors of five-year recurrence/survival. METHODS: Data were extracted from the Recurrence After Whipple's (RAW) study, a multicentre retrospective study of PD patients with a confirmed head of pancreas or periampullary malignancy (June 1st, 2012-May 31st, 2015). Patients with AA who developed recurrence/died within five-years were compared to those who did not. RESULTS: 394 patients were included and actual five-year survival was 54%. Recurrence affected 45% and the median time-to-recurrence was 14 months. Local only, local and distant, and distant only recurrence affected 34, 41 and 94 patients, respectively (site unknown: 7). Among those with recurrence, the most common sites were the liver (32%), local lymph nodes (14%) and lung/pleura (13%). Following multivariable tests, number of resected nodes, histological T stage > II, lymphatic invasion, perineural invasion (PNI), peripancreatic fat invasion (PPFI) and ≥1 positive resection margin correlated with increased recurrence and reduced survival. Furthermore, ≥1 positive margin, PPFI and PNI were all associated with reduced time-to-recurrence. CONCLUSIONS: This multicentre retrospective study of PD outcomes identified numerous histopathological predictors of AA recurrence. Patients with these high-risk features might benefit from adjuvant therapy.

CONTEXT: High-intensity interval training (HIIT) has been widely used to prevent and treat cardiovascular risk factors in adolescents and adults; nevertheless, the available evidence in children is scarce. OBJECTIVE: To synthesize evidence regarding the effectiveness of HIIT interventions on improving cardiovascular risk factors and cardiorespiratory fitness (CRF) in children from 5 to 12 years old. DATA SOURCES: We searched 5 databases, Medline, Embase, SPORTDiscus, the Cochrane Library, and Web of Science. STUDY SELECTION: Randomized controlled trials (RCTs) evaluating the effectiveness of HIIT interventions on cardiometabolic risk factors and CRF in children were included. DATA EXTRACTION: Meta-analyses were conducted to determine the effect of HIIT on body composition, cardiometabolic and CRF variables in comparison with nontraining control groups. RESULTS: A total of 11 RCTs and 512 participants were included. The results of the meta-analysis revealed a significant improvement in peak oxygen uptake (standardized mean difference [SMD] = 0.70, 95% confidence interval [CI] = 0.28 to 1.12; P = 0.001], in total cholesterol [SMD = -1.09, 95% CI = -1.88 to -0.30; P = 0.007], in low-density lipoprotein cholesterol [SMD = -1.28, 95% CI = -2.34 to -0.23; P = 0.017] and triglycerides [SMD = -0.71, 95% CI = -1.15 to -0.28; P = 0.001) levels. LIMITATIONS: Because of the small number of available RCTs, it was not possible to conduct a subgroup analysis or a linear meta-regression analysis. CONCLUSIONS: HIIT is a feasible and time-efficient approach for improving CRF, total cholesterol, low-density lipoprotein cholesterol, and triglycerides levels in children.

BACKGROUND: No previous systematic review has examined the effect of high-intensity interval training (HIIT) interventions on body composition, cardiometabolic risk factors and cardiorespiratory fitness (CRF) in healthy schoolchildren from 5 to 12 years old. METHODS: This study will be conducted by following the guideline of the preferred reporting items for systematic review and meta-analysis protocols. An electronic search in MEDLINE (via PubMed), EMBASE (via Scopus), SPORTDiscus, Cochrane Library and Web of Science databases of all dates from inception will be conducted. We will include randomized controlled trials aimed to assess the effectiveness of HIIT to improve cardiometabolic risk factors, body composition, and CRF in children. Two authors will perform the study selection and data collection; disagreements will be solved by a third reviewer. The methodological quality of studies will be assessed by the Cochrane Collaboration's tool for assessing risk of bias (RoB2). Data analysis and synthesis will be performed by Comprehensive Meta-analysis Software and StataSE software, version 15. CONCLUSION: The results should be disseminated through publication in a peer-reviewed journal. Since the data used in systematic reviews of this type will be extracted exclusively from published studies, approval form and ethics committee will not be required.

INTRODUCTION: Few studies compare the direct impact of pancreatoduodenectomy (PD) on the patient's quality of life (QOL). The effect of PD in QOL, comparing the preoperative vs. postoperative status, was analyzed. METHOD: A prospective single-center study was performed. PD patients in a 2-year period were included. A general QOL instrument was applied preoperative, 1, 3, 6, and 12 months after surgery and compared with national norms. RESULTS: Thirty-seven patients were recruited. Twenty of 37 were female. Ampullary carcinoma 14/37, ductal adenocarcinoma in 9/37, and other malignant neoplasms 14/37 were diagnosed. Mortality was absent; 48.6% had complications, 13.5 % required reoperation. Three (median) and 4 (mode) questionnaires were answered per individual. 85 % answered the last questionnaire. 4/37 had cancer related death before a year. Median follow-up was 29 (3-72) months. QOL diminished a month after surgery, physical function (67 vs 40, p<0.0001) and emotional role (37 vs 17, p<0.032) did so significantly. Three months after surgery QOL improved yet not significantly. Six and 12 months postoperatively, physical role (9 vs 49, p=0.001), physical pain (51 vs 71, p=0.01), social function (52 vs 63, p=0.014), vitality (54 vs 64, p=0.018), and emotional role (41 vs 69, p=0.006) improved significantly. DISCUSSION: PD has a favorable impact in quality of life as demonstrated by the improvement of most parameters assessed in the postoperative period.

BACKGROUND: Improvements in bile duct injury repairs have been shown in centres with specialized surgeons. The aim of the present study was to demonstrate the temporal change in the pattern of referral, technical variation associated with repair and long-term outcome of bile duct injuries at a tertiary referral centre in Mexico City. METHODS: A retrospective case note review was performed. Patients were divided into two groups: group I (GI) 1990 to 2004 and group II (GII) 2005-2008, and appropriate statistical analysis undertaken. RESULTS: Over a 20-year period, 312 patients with iatrogenic bile duct injuries required surgical treatment (GI = 169, GII = 140 patients). All injuries were reconstructed using a Roux-en-Y hepaticojejunostomy. The proportion of patients who had undergone a laparoscopic cholecystectomy increased from 24% to 36% (P = 0.017) over the two time periods. In the second time period there was an increase in segment IV and V partial resections (P = 0.020), a reduction in the use of transanastomotic stents (42% to 2%, P = 0.001) and an increase in the proportion of patients requiring a neoconfluence (2% to 11%, P = 0.003). In the second time period, the number of patients requiring a hepatectomy during repair (2% to 1%, P = 0.001), a portoenterostomy (16% to 9%, P = 0.060) or a double-barrel hepatico-jejunostomy (5% to 1%, P = 0.045) significantly decreased. During follow-up, patients in the second time period had a reduction in the incidence of post-operative cholangitis (11% to 6%, P = 0.310) and the frequency of post-operative anastomotic stenoses (13% to 5%, P = 0.010). Mortality remained low throughout the series but was absent in the second group. CONCLUSIONS: Changes in technique and growing experience of the multidisciplinary team improved operative and long-term results of bile duct injury repair.

To review the classification and general guidelines for treatment of bile duct injury patients and their long term results. In a 20-year period, 510 complex circumferential injuries have been referred to our team for repair at the Instituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubirán" hospital in Mexico City and 198 elsewhere (private practice). The records at the third level Academic University Hospital were analyzed and divided into three periods of time: GI-1990-99 (33 cases), GII- 2000-2004 (139 cases) and GIII- 2004-2008 (140 cases). All patients were treated with a Roux en Y hepatojejunostomy. A decrease in using transanastomotic stents was observed (78% vs 2%, P = 0.0001). Partial segment IV and V resection was more frequently carried out (45% vs 75%, P = 0.2) (to obtain a high bilioenteric anastomosis). Operative mortality (3% vs 0.7%, P = 0.09), postoperative cholangitis (54% vs 13%, P = 0.0001), anastomosis strictures (30% vs 5%, P = 0.0001), short and long term complications and need for reoperation (surgical or radiological) (45% vs 11%, P = 0.0001) were significantly less in the last period. The authors concluded that transition to a high volume center has improved long term results for bile duct injury repair. Even interested and tertiary care centers have a learning curve.
RESUMEN
BACKGROUND: Bile duct injuries (BDI) have a wide array of presentation. Left partial injuries (Strasberg D) of the hepatic duct are the result of excessive traction, which dissects the hepatic hilum and provokes medial perforations without continuity loss. Right partial injuries (Strasberg A, B and C) are produced by direct damage to the hepatic duct or isolated injury to the right and accessory ducts. It is important to determine frequency, spectrum and treatment outcome of this BDI in the surgical scenario. METHODS: Patients with BDI who underwent surgical treatment in our hospital were reviewed, right and left partial injuries were selected. Demographic, clinical and therapeutic data were analyzed. RESULTS: In a 16-year period, 405 patients underwent surgical treatment of BDI. 31 (8%) were classified as a left partial injury (Strasberg D): 23 injuries at the common hepatic duct treated with a Hepatojejunostomy (HJ); four at the confluence level which received a HJ with neoconfluence construction; two partial injuries in the left hepatic duct underwent a selective left HJ; and two complete occlusions of the left hepatic duct, one treated with a partial hepatectomy and the last case underwent a partial HJ. Right partial injuries (Strasberg A, B or C) were identified in 21 cases (5%), their treatment was tailored according to the type of BDI (conservative, selective HJ, or hepatectomy). CONCLUSIONS: In our series the frequency of left and right partial BDI injuries was 8% and 5%, respectively. The spectrum of analyzed injuries included four subtypes for the left partial and eight for the right partial lesions. Most BDI in the two analyzed groups presented concomitant devascularization of the extra-hepatic ducts, therefore receiving surgical treatment rather than endoscopic treatment was done.

BACKGROUND & AIMS: Mucin-producing neoplasms (MPNs) of the pancreas include mucinous cystic neoplasms (MCNs) and main-duct, branch-duct, and combined intraductal papillary mucinous neoplasms (IPMNs). MCNs and branch-duct IPMNs are frequently confused; it is unclear whether main-duct, combined, and branch-duct IPMNs are a different spectrum of the same disease. We evaluated their clinical and epidemiologic characteristics. METHODS: Patients who underwent resection for histologically confirmed MPNs were identified (N = 557); specimens were reviewed and eventually reclassified. RESULTS: One hundred sixty-eight patients (30%) had MCNs, 159 (28.5%) had branch-duct IPMNs, 149 (27%) had combined IPMNs, and 81 (14.5%) had main-duct IPMNs. Patients with MCNs were significantly younger and almost exclusively women; 44% of patients with main-duct or combined IPMNs and 57% of those with branch-duct IPMNs were women. MCNs were single lesions located in the distal pancreas (95%); 11% were invasive. IPMNs were more frequently found in the proximal pancreas; invasive cancer was found in 11%, 42%, and 48% of branch-duct, combined, and main-duct IPMNs, respectively (P = .001). Patients with invasive MCN and those with combined and main-duct IPMNs were older than those with noninvasive tumors. The 5-year disease-specific survival rate approached 100% for patients with noninvasive MPNs. The rates for those with invasive cancer were 58%, 56%, 51%, and 64% for invasive MCNs, branch-duct IPMNs, main-duct IPMNs, and combined IPMNs, respectively. CONCLUSIONS: MPNs comprise 3 different neoplasms: MCNs, branch-duct IPMNs, and main-duct IPMNs, including the combined type. These tumors have specific clinical, epidemiologic, and morphologic features that allow a reasonable degree of accuracy in preoperative diagnosis.

Objetivo: Hallar el grado de satisfacción laboral en una muestra de médicos asistenciales de una mutua de accidentes de trabajo y enfermedades profesionales (MATEPSS), determinando su relación con una serie de aspectos sociodemográficos y laborales y con su repercusión sobre la prescripción de incapacidad temporal. Material y método: Se realizó un estudio transversal en una muestra final de 156 médicos (muestra total de 250 médicos), repartidos por toda la geografía española de una MATEPSS, a los que se les aplicó el Maslach burnout inventory, y un cuestionario de elaboración propia que mide una serie de variables sociodemográficas. Sobre 131 médicos pertenecientes a la muestra mencionada anteriormente, se realizó un estudio sobre la influencia que el burnout y esas variables sociodemográficas podían ejercer sobre la prescripción de bajas laborales. Se utilizó el paquete estadístico SPSS, realizándose dos métodos estadísticos diferentes. Resultados: El primer método arrojó los siguientes resultados: la oportunidad de padecer grado alto de cansancio emocional se asocia de forma significativa (p<0,05), con padecer la sensación de carencia de material y de tiempo, no sentirse feliz con su trabajo, desear cambiarse de profesión y con el sentimiento de que los problemas laborales afectaban a su vida personal. El grado alto de despersonalización, con la sensación de que faltaba material para el trabajo diario, no sentirse feliz con su labor y sentir la intromisión habitual de los superiores en su trabajo, por otro lado, aparecieron como factores protectores contra la despersonalización, el ser mujer y trabajar exclusivamente en la mutua. La falta de realización personal aparece significativamente asociada con el pensamiento de no estar cumpliendo con sus expectativas profesionales, con creer que falta formación para que el personal desarrolle sus funciones correctamente, con desear cambiar de empresa y de profesión y con sentir la intromisión habitual de los superiores en su trabajo. Con respecto al estudio de las variables relacionadas con la hiperprescripción de bajas laborales llevado a cabo en la muestra de 131 médicos mencionada anteriormente, se asocia significativamente a la carencia de tiempo y de medios humanos, pero si realizamos el estudio por un segundo método estadístico, también aparece relación con la variable "intromisión habitual del jefe en su labor" aunque éste resultará ser un factor de protección, y desaparece la variable "sentir carencia de medios humanos". Conclusiones: el perfil del médico asistencial de mutua que padece burnout es el de un varón, pluriempleado, que no se siente feliz con su trabajo, y de hecho, cree que no está cumpliendo con sus expectativas profesionales. Los problemas laborales influyen en su vida personal. Considera que existe falta de material y tiempo para concluir sus tareas diarias y que el personal no está lo suficientemente bien formado para el desempeño de sus funciones, siente una intromisión habitual de sus superiores en su labor habitual y desea cambiar de empresa e incluso de profesión. Además, se trata de un médico especialista en medicina de familia. El perfil del hiperprescriptor de bajas laborales es el de un médico, con independencia del sexo al que pertenece, y de si padece o no burnout, siente falta de tiempo para terminar su trabajo diario, falta de medios materiales y siente una frecuente intromisión de sus superiores en su labor habitual lo que le lleva a firmar un menor número de bajas laborales (AU)

CONTEXT: Heterotopic pancreas is defined as ectopic pancreatic tissue without vascular or anatomic continuity with the normal pancreas. The spleen is a rare site of origin. This case report describes a patient with a malignant insulinoma which originated from an intrasplenic heterotopic pancreas. CASE REPORT: A 46-year-old man with three previous episodes of neuroglucopenic and adrenergic symptoms was referred to our hospital. A fasting test was performed and discontinued due to hypoglycemic symptoms. Preoperative studies failed to demonstrate any pancreatic lesions. However, a heterogeneous encapsulated tumor in the spleen was found on MRI. During surgery, only the splenic tumor was found, with neither vascular nor anatomical connections to the normal pancreas. Pathology reported a malignant insulinoma. Insulin and proinsulin were documented by immunohistochemistry. After one year of follow up, the patient is free of symptoms and no recurrent disease has been documented. DISCUSSION: Only seven cases of splenic heterotopic pancreas have been reported, six with cystic mucinous neoplasms. In addition, only one case of a malignant insulinoma arising from heterotopic pancreas has previously been described. This is the second case reported of an insulinoma arising from heterotopic pancreas and the first to originate from intrasplenic heterotopia.

BACKGROUND: Biliary complications after orthotopic liver transplantation (OLT) are multifactorial in origin. In most series, the frequency of such complications ranges from 5-20%. Most can be treated by endoscopy and/or interventional radiology. For cases in which this option is not successful, surgical approach is indicated. We report the results of reoperation using an intrahepatic bilioenteric anastomosis. METHODS: The medical charts of patients with biliary complications after OLT during a 10-year period (1997-2007), who failed to respond to nonsurgical treatment and were surgically treated, were reviewed. Roux-en-Y hepatojejunostomy was performed. Segments IV and V were partially removed after cutting the hilar plate, thus obtaining healthy ducts without ischemic or inflammatory reaction and allowing a wide hepatojejunostomy. RESULTS: Five cases (8.4%) with biliary complications after duct-to-duct anastomosis not amenable to further endoscopic management or interventional radiology were identified. Hepaticojejunostomy was achieved in all cases (wide, tension-free, nonischemic, fine hydrolyzable sutures), and segments IV and V were partially removed. No cholangitis, jaundice, and liver function test abnormalities were present in the postoperative. Mean follow-up was 24 months. Only one patient died of causes not related to bile duct reconstruction during follow-up. CONCLUSIONS: Intrahepatic hepatojejunostomy with partial resection of segments IV and V offers an excellent therapeutic alternative for biliary complications that require a surgical approach after OLT.

BACKGROUND: Nodal metastasis is considered a major prognostic factor in patients with ampulla of Vater carcinoma (AVC). No study has investigated the significance of the ratio between metastatic and resected/examined lymph nodes (LNR) in patients with AVC. METHODS: Demographic, operative, and pathology data, including number of resected/evaluated nodes and LNR, were collected from patients who underwent pancreaticoduodenectomy with radical intent for invasive AVC from 1990 to 2005. Survival rates and recurrence patterns were evaluated and predictors were identified. RESULTS: In 90 evaluable patients (51 males, 39 females, median age 62.5 years), 5-year disease-specific survival (DSS) was 61%. The median number of resected/evaluated nodes was 16 (range: 5-47); 50% of the patients had nodal metastases. The 5-year DSS according to LNR was 75%, 49%, 38%, and 0% for LNR = 0, LNR >0 and < or =0.2, LNR >0.2, and < or =0.4, and LNR >0.4 (P = 0.002), respectively. The 5-year DSS was 81% in patients with >16 resected/evaluated nodes compared with 45% in those with < or =16 resected/evaluated nodes (P = 0.001). On multivariate analysis LNR and a number of resected/evaluated nodes >16 were significant predictors of survival; a number of resected/evaluated nodes >16 was also the only independent predictor of recurrence. CONCLUSIONS: After curative resection for AVC, LNR and a cutoff of 16 resected/evaluated nodes are powerful prognostic factors. LNR might represent a major parameter for patient stratification in adjuvant treatment trials.

OBJECTIVE: To describe the management and impact of pancreatic fistulas in a high-volume center. DESIGN: Retrospective case series. SETTING: Tertiary academic center. PATIENTS: Five hundred eighty-one consecutive patients who underwent pancreaticoduodenectomy from January 2001 through June 2006. MAIN OUTCOME MEASURES: Development of a pancreatic fistula (defined as > 30 mL of amylase-rich fluid from drains on or after postoperative day 7, or discharge with surgical drains in place, regardless of amount); the need for additional interventions or total parenteral nutrition; other morbidity; and mortality. RESULTS: Seventy-five patients (12.9%) developed a pancreatic fistula. Fistulas were managed with gradual withdrawal of surgical drains. This allowed for patient discharge and eventual closure at a mean of 18 days in 38.7% of cases; these were classified as low-impact fistulas. The remaining 46 patients (61.3%) had an associated abscess, required percutaneous drainage or total parenteral nutrition, or developed bleeding; these were classified as high-impact fistulas and closed a mean of 35 days after surgery. Standard 30-day in-hospital mortality was 1.9% for all pancreaticoduodenectomies and 6.7% for those who developed a pancreatic fistula. The overall fistula-related mortality was 9.3% (7 patients), all but 1 of which was related to major hemorrhage. CONCLUSIONS: More than one-third of pancreatic fistulas are clinically insignificant (low impact). The remaining 60% of fistulas have a high clinical impact and nearly an 8-fold increase in overall mortality.
