description: Context Despite improvement in mortality, surgical morbidity in pancreatic surgery remains high, and infectious complications have a main role. Objective To evaluate the role of intra-operative bile culture as a guide for post-operative antibiotic therapy in case of infectious complications. Methods From January 2010 to June 2012 we realized 136 pancreatico­duodenectomies for periampullary diseases. Intra-operative bile sampling and postoperative sampling from peri-pancreatic drainage fluid for culture were performed in 110 patients (81%) who were enrolled in this study. Forty-four patients (40%) experienced infectious complications (Group A) while 66 patients (60%) did not (Group B). Infectious surgical complications were: 31 POPFs (13 grade A, 18 grade B-C), 6 abdominal abscesses, 5 biliary fistulas, 1 gastro-duodenal fistula and 19 wound infections (some patients has more than one complication). Data were collected prospectively. Results Bile cultures resulted positive in 61/110 patients (56%), there were no differences in the rate of infected bile between the two Groups (57% vs. 55%); preoperative biliary stenting was strongly correlated with biliary infection (100% in stented patients vs. 18% in non-stented; P<0.001). Drainage fluid cultures resulted positive in 66/110 (61%) patients: in Group A they were positive in 40/44 patients (91%) while in Group B in 26/66 patients (40%) (P<0.05, chi-square test). In Group A negative drainage cultures belonged to patients who developed grade A POPF or wound infection. In Group B positive drainage cultures belonged to patients with infected bile in 62% of cases; in 19% of cases cultures were contaminated by skin germs (Staphylococcus). From drainage fluid culture, we isolated 102 germs (55 Gram +, 41 Gram -, 8 fungi) in Group A and 37 germs (26  Gram +, 11  Gram -) in Group B; 44/102 germs (43%) and 12/37 germs (32%) in Groups A and B, respectively were identical to that found in bile cultures. Conclusion In patients who develop abdominal infectious complications the high concordance between bile and drainage fluid cultures suggests that bile cultures can be useful as a guide for postoperative antibiotic therapy. The presence of infected bile can cause contamination of peritoneal fluid even in uncomplicated patients but it has no clinical relevance.

description: We study two species of (or spin-1/2) fermions with short-range intra-species repulsion in the presence of opposite (effective) magnetic field, each at Landau level filling factor 1/3. In the absence of inter-species interaction, the ground state is simply two copies of the 1/3 Laughlin state, with opposite chirality, representing the fractional topological insulator (FTI) phase. We show this phase is stable against moderate inter-species interactions. However strong enough inter-species repulsion leads to phase separation, while strong enough inter-species attraction drives the system into a superfluid phase. We obtain the phase diagram through exact diagonalization calculations. The FTI-superfluid phase transition is shown to be in the (2+1)D XY universality class, using an appropriate Chern-Simons-Ginsburg-Landau effective field theory.

description: If $x$ and $y$ are roots in the root system with respect to the standard (Tits) geometric realization of a Coxeter group $W$, we say that $x$ \emph{dominates} $y$ if for all $w\in W$, $wy$ is a negative root whenever $wx$ is a negative root. We call a positive root \emph{elementary} if it does not dominate any positive root other than itself. The set of all elementary roots is denoted by $\E$. It has been proved by B. Brink and R. B. Howlett (Math. Ann. \textbf{296} (1993), 179--190) that $\E$ is finite if (and only if) $W$ is a finite-rank Coxeter group. Amongst other things, this finiteness property enabled Brink and Howlett to establish the automaticity of all finite-rank Coxeter groups. Later Brink has also given a complete description of the set $\E$ for arbitrary finite-rank Coxeter groups (J. Algebra \textbf{206} (1998)). However the set of non-elementary positive roots has received little attention in the literature. In this paper we answer a collection of questions concerning the dominance behaviour between such non-elementary positive roots. In particular, we show that for any finite-rank Coxeter group and for any non-negative integer $n$, the set of roots each dominating precisely $n$ other positive roots is finite. We give upper and lower bounds for the sizes of all such sets as well as an inductive algorithm for their computation.

description: Context Laparoscopy has revolutionized abdominal surgery becoming the standard approach for many operations. The “da Vinci” surgical system overcomes most of the inherent technical limitations of laparoscopy. Objective We test whether the robotic approach can improve the outcome of pancreatic resections, which often require challenging dissection and complex digestive reconstructions. Methods One-hundred and six consecutive robotic pancreatic resections were performed between October 2008 and June 2012. There were 40 males and 66 females (62%), with a mean age of 57 years (range 21-80 years) and a mean BMI of 24.6 Kg/m2. Thirty-nine patients underwent pancreaticoduodenectomy (PD) (37%), 47 distal pancreatectomy (DP) (44%), 10 total pancreatectomy (10%), 7 tumor enucleation (6%) and 3 central pancreatectomy (3%). Since our activity spans over about a 4-year period, data were analyzed according to the time of surgery, to verify progress in the learning curve: 17 patients were operated on between October 2008 and September 2009, 22 patients between October 2009 and September 2010, 32 patients between October 2010 and September 2011 and 35 patients during the last 9 months (from October 2011 to June 2012). Results No patient was converted to laparoscopy or open surgery. Mean operative time (OT) was 442.8 minutes. In the first period OT was 512 min for PD and 420 for DP. The mean number of lymph nodes examined (LN) was 16.8; 31.2 for PD and 11.9 for DP. Pancreatic fistula (PF) occurred in 41% of the patients. In the second, OT was 596 min for PD and 402 for DP. The LN was 16.7; 27.2 for PD and 10.0 for DP. PF was amounted 36.3%. In the third, OT was 583 min for PD and 288 for DP. The LN was 28.7; 36.0 for PD and 19.1 for DP. PF was amounted 36.6%. In the fourth, OT was 590 min for PD and 250 for DP. The LN was 30; 32 for PD and 20 for DP. PF was amounted 35%. Fifty-six benign/low-grade tumors and 50 cancers were diagnosed. Surgical margins were all negative. Post-operative mortality was nil, morbidity was 56% and mean hospital stay was 16 days. Conclusions Robot-assisted pancreatic resections can be safely performed in selected patients. Despite the existence of a learning curve, experienced pancreatic surgeons are not expected to pay to robotics the same price that they would have been asked for by laparoscopy.

Does interlimb transfer of locomotor adaptations depend on limb dominance?
Creators: name: Crombeen, Matthew
Publisher: name: University of British Columbia
Year: 2013

description: Generalization of these adaptations have been found to occur across task, workspace and between limbs. Interlimb adaptation transfer appears to depend on limb dominance. Transfer of adaptation from the non-dominant to the dominant limb involves faster rate of adaptation in movement trajectory patterns, while transfer from the dominant limb to the non-dominant limb involves a faster rate of adaptation positioning related parameters of movement. Although such observations are robust for upper limb adaptations, the extent of interlimb transfer during locomotor tasks is still unclear. The objective of this study was to determine whether locomotor adaptations to a velocity-dependent resistance transfers asymmetrically depending on dominance associated with the legs. It was expected that transfer of adaptation will occur according to dominance, with the dominant limb showing faster adaptation in terms of foot trajectory following non-dominant limb learning; and the non-dominant limb showing faster adaptation in terms of heel strike position following dominant limb learning. Twenty able-bodied adults who were right hand and right leg dominant walked unipedally in the Lokomat robotic gait orthosis, which applied a velocity-dependent resistance against leg movements. The resistance was scaled to 10% of the individual’s maximum voluntary contraction of the hip and knee flexors. Subjects performed a heel targeting task that was scaled to their individual step length. Subjects were then randomly assigned to either the RL training group, testing transfer to the non-dominant limb, or to the LR training group, testing transfer to the dominant limb. Muscle activity (surface electromyography) and joint kinematics were recorded from the lower limbs. The adaptation rate in the initial foot trajectory slope and end point error were compared between the groups and across trials using a 2 by 3 repeated measures ANOVA. There was no difference between the groups for either initial foot trajectory slope (p = 0.106) or end point error (p = 0.763). There was also no evidence for transfer of motor adaptations between the lower limbs in the other gait variables. These results suggest that interlimb transfer of locomotor adaptations is limited, but further studies are warranted to understand the neuromechanical mechanisms controlling locomotor adaptations.

description: The notion of $r$-crossing and $r$-nesting of a complete matching was introduced and a symmetry property was proved by Chen et al. [Trans. Amer. Math. Soc. 359 (2007) 1555-1575]. We consider random matchings of large size and study their maximal crossing and their maximal nesting. It is known that the marginal distribution of each of them converges to the GOE Tracy-Widom distribution. We show that the maximal crossing and the maximal nesting becomes independent asymptotically, and we evaluate the joint distribution for the Poissonized random matchings explicitly to the first correction term. This leads to an evaluation of the asymptotic of the covariance. Furthermore, we compute the explicit second correction term in the distribution function of two objects: (a) the length of the longest increasing subsequence of Poissonized random permutation and (b) the maximal crossing, and hence also the maximal nesting, of Poissonized random matching.

description: Context Small intestine bacterial overgrowth (SIBO) is considered as a factor possibly worsening symptoms and nutritional status in patients with chronic pancreatitis (CP) and pancreatic exocrine insufficiency (PEI) not responding to treatment. However, few studies evaluated the rate of SIBO in CP patients (range of positivity ranging 0-92%), employed different substrates and non-standardized procedures, and often investigated CP patients with previous resective surgery (cause of SIBO per se). Objective To assess the prevalence of SIBO in CP patients without history of resective surgery as compared with a control group. Secondary aim is to analyze factors related with SIBO in CP patients. Methods CP patients and controls (outpatients with upper-GI unspecific symptoms; exclusion criteria CP, IBD, celiac disease or previous surgery), had SIBO evaluated by H2 glucose breath test (GBT) with a standard protocol according to Rome consensus conference. Positivity rate, basal, peak over basal (HOB) and H2 values at 120 minutes were evaluated. For CP patients, relation between GBT results, abdominal symptoms, nutritional and clinical variables was analyzed. Results Twenty-six CP patients and 22 controls were enrolled. Of the 26 patients (alcoholic aetiology in 11), 13 had PEI, 5 advanced CP (defined by M-ANNHEIM severity index) and none had previous resective surgery. GBT positivity rate was 5/26 (19.2%) in cases and 3/21 (13.6%) in controls (P=0.71). Mean H2 basal excretion (9.78 ppm in CP vs. 5.47 ppm in controls; P=0.13), HOB (4.6 ppm in CP vs. 4.52 ppm in controls; P=0.95) and H2 at 120 minutes (4.86 in CP vs. 2.20 in controls; P=0.08) were not different between the two groups. Diagnosis of SIBO in the CP group was not correlated with presence of PEI, severity of disease, abdominal symptoms, pancreatic enzymes and proton pump inhibitors therapy. Conclusion The rate of SIBO seems similar in CP patients without previous resective surgery and controls. CP patients with SIBO did not have more severe disease, more symptoms or worse nutritional status. These findings do not suggest a relevant impact of SIBO on the clinical course and management of uncomplicated CP but our findings deserve confirmation in a larger cohort.

description: Context Early diagnosis of pancreatic ductal adenocarcinoma (PDA) is still a challenge. In the last decade many studies showed that the air exhaled by subjects suffering from lung and breast tumor shows peculiar profiles of volatile organic compounds (VOCs). The possible causal factors of PDA are able to alter the concentration of some VOCs in the alveolar air which can be collected with an easy-to-use, cheap and reliable device. Objective To determine a VOCs profile in the alveolar air able to discriminate patients suffering from PDA. Methods Air samples were obtained from patients affected by PDA cyto-histologically confirmed admitted in the Surgical Unit B of Verona University Hospital (Study Group). Patients characteristics, clinical and biohumoral data, surgical procedures and histological specimen reports were prospectively collected. The same air samples were collected from healthy subjects (Control Group) and in the environmental air of the rooms where the subjects studied were staying. Air samples were analysed by an ion molecule reaction-mass spectrometry analysis (IMR-MS). Through principal components analysis and multivariate logistic regression, a predictive model was created to distinguish subjects with PDA from control subjects. Results The concentration of 92 compounds among VOCs and gases (CO2 and O2 included) was measured in 75 patients end-tidal breath and in 144 control subjects. The predictive model was built on 65 cases and 102 controls with ages between 40 and 75 years and was based on 10 VOCs significantly and independently associated with the outcome, showing sensitivity and specificity values of 98.67% and 95.10%, respectively and an area under the ROC curve of 0.9887. Conclusion Using a profile of some VOCs we identify an algorithm able to discriminate subjects with pancreatic adenocarcinoma from control subjects with the best sensitivity and specificity ever reported by a single test. The test is cheap, non invasive and reproducible. We believe that it could be applied extensively and it could represent a screening test in high risk population for pancreatic ductal adenocarcinoma.

description: Context Robotic distal pancreatectomy (RDP) is a safe and feasible operation with increasing reports in the literature. The debate is still open whether a hybrid approach could be a viable option versus a fully robotic operation. Objective To analyze the preliminary experience with RDP comparing a hybrid versus a fully robotic approach. Methods All patients undergone RDP were analyzed. A hybrid approach was initially preferred, using laparoscopic harmonic scalpel to perform some steps of operation, including pancreatic gland transection. Patients’ characteristics, pre- and intra-operative data as well as postoperative outcome were prospectively collected in an institutional database. Size of tumor, time of operation and robotic docking, blood loss, post-operative pancreatic fistula (POPF), intra-abdominal fluid collection, and postoperative stay were recorded. Results Five consecutive patients (4 females) underwent RDP between December 2011 and July 2012. Mean age was 55 years (range 34-77 years); mean tumor size was 35 mm (range 10-53 mm). Two spleen preserving RDP were performed. Mean operative time was 275 min (range 210-450 min); robotic procedure time was 158 min (range 60-285 min). One patient was converted to open procedure because of uncontrolled splenic artery bleeding during pancreatic gland transection. Two patients experienced blood loss requiring intra-operative transfusion. One patient was re-operated on because of intra-abdominal fluid collection and partial splenic infarction developed on 5 post-operative day. Two POPF developed (1 grade A and 1 grade B). Mean hospital stay was 13.5 days (range 10-20 days). Histological specimens were consisted of 2 neuroendocrine tumors and 3 mucinous cystadenomas. Two asymptomatic intra-abdominal fluid collections were followed with periodic US investigation and up to now do not necessitate of any active treatment (follow up ended on July 2012). Conclusion A hybrid approach was initially preferred to perform RDP taking origin from more than a decade of experience in laparoscopic distal pancreatectomy. On the basis of overall results obtained we have decided to adopt a fully robotic technique to perform RDP.

description: We present a method for obtaining outer valence quasiparticle excitation energies from a DFT-based calculation, with accuracy that is comparable to that of many-body perturbation theory within the GW approximation. The approach uses a range-separated hybrid density functional, with asymptotically exact and short-range fractional Fock exchange. The functional contains two parameters - the range separation and the short-range Fock fraction. Both are determined non-empirically, per system, based on satisfaction of exact physical constraints for the ionization potential and many-electron self-interaction, respectively. The accuracy of the method is demonstrated on four important benchmark organic molecules: perylene, pentacene, 3,4,9,10-perylene-tetracarboxylic-dianydride (PTCDA) and 1,4,5,8-naphthalene-tetracarboxylic dianhydride (NTCDA). We envision that for finite systems the approach could provide an inexpensive alternative to GW, opening the door to the study of presently out of reach large-scale systems.

description: A sharp potential barrier at the Si/SiGe interface introduces valley splitting (VS), which lifts the 2-fold valley degeneracy in strained SiGe/Si/SiGe quantum wells (QWs). This work examines in detail the effects of Si/SiGe interface disorder on the VS in an atomistic tight binding approach based on statistical sampling. VS is analyzed as a function of electric field, QW thickness, and simulation domain size. Strong electric fields push the electron wavefunctions into the SiGe buffer and introduce significant VS fluctuations from device to device. A Gedankenexperiment with ordered alloys sheds light on the importance of different bonding configurations on VS. We conclude that a single SiGe band offset and effective mass cannot comprehend the complex Si/SiGe interface interactions that dominate VS.

In order to obtain finite results, we assume a dipole form factor for the nucleon-quark-diquark coupling, instead of a point-like coupling. The results are compared with the time-reversal-odd interaction-independent twist-3 TMDs calculated in the same model.

We show that if $S_n$ converges in finite dimensional distributions to a càdlàg process, then $S_n+y_n$ converges a.s. pathwise uniformly over $[0,1]$, for some $y_n\in D([0,1];E)$. This result extends the Itô-Nisio theorem to the space $D([0,1];E)$, which is surprisingly lacking in the literature even for $E=R$. The main difficulties of dealing with $D([0,1];E)$ in this context are its nonseparability under the uniform norm and the discontinuity of addition under Skorohod's $J_1$-topology. We use this result to prove the uniform convergence of various series representations of càdlàg infinitely divisible processes. As a consequence, we obtain explicit representations of the jump process, and of related path functionals, in a general non-Markovian setting. Finally, we illustrate our results on an example of stable processes. To this aim we obtain new criteria for such processes to have càdlàg modifications, which may also be of independent interest.

description: Context Robotic surgery entails specific issues that are not present, or are not equally relevant, in open surgery or conventional laparoscopy. Instrument traffic (IT) is one of such issues. IT is the time during which surgery is paused because the surgeon at the console is waiting for the action of the surgeon the table (e.g., instrument change, camera cleaning, introduction/withdrawal of needles). Objective We provide the first objective evaluation of IT during robotic pancreaticoduodenectomy (PD). Methods The operative videos of 12 robot-assisted PDs were reviewed to define IT. The analysis included: crude IT time (CITT), relative IT time (RITT) (defined as the percentage of operative time spent for IT), number of robotic instruments changes (RIC), time spent for RIC (TRIC), number of pure laparoscopic actions (PLA), and time spent for PLA (TPLA). Figures were estimated for the entire operation as well as for dissection and reconstruction phases. Details on pancreaticojejunostomy (PJ) or hepaticojejunostomy (HJ) were related to IT to define their relative impact on operative time. Results Mean operative time was 517 min (range 420-600 min). Mean CITT was 3,681.6 sec (RITT 11.89%). Mean RIC or PLA was 315.7. Each RIC or PLA paused surgery for 11.8 sec. Mean RIC was 184.4 (TRIC 2,633.8 sec). Mean PLA was 131.4 (TPLA 1,039.5 sec). Mean dissection time was 326.9 min. Mean CITT was 2,095.1 sec (RITT 10.68%). Mean RIC was 105.8 (TRIC 1,645.2 sec). Mean PLA was 35.7 (TPLA 382.5 sec). Each RIC or PLA paused surgery for 14.4 sec. PJ was made by invaginating technique or duct-to-mucosa. The last one required fewer stitches, but did not reduced CITT or RIC. HJ was performed using either 4 half running sutures or interrupted external stitches plus inner half running sutures. Despite similar CITT the former technique was associated with fewer RIC. Conclusions Some 12% of operative time of laparoscopic robot-assisted PD is wasted because of IT. Since in this series operative time of robotic PD averaged 517 minutes, IT prolonged surgery of more than one hour. Technology improvements and/or refinements in surgical technique are expected to reduce IT during robotic PD.

title: Advanced sequencing technologies applied to human cytomegalovirus

description: The betaherpesvirus human cytomegalovirus (HCMV) is a ubiquitous viral pathogen. It is the most common cause of congenital infection in infants and of opportunistic infections in immunocompromised patients worldwide. The large double-stranded DNA genome of HCMV (236 kb) contains several genes that exhibit a high degree of variation among strains within an otherwise highly conserved sequence. These hypervariable genes encode immune escape, tropism or regulatory factors that may affect virulence. Variation arising from these genes and from an evolutionary history of recombination between strains has been hypothesised to be linked to disease severity. To investigate this, the HCMV genome has been scrutinised in detail over the years using a variety of molecular techniques, most looking only at one or a few of these genes at a time. The advent of high-throughput sequencing (HTS) technology 20 years ago then started to enable more in-depth whole-genome analyses. My study extends this field by using both HTS and the more recently developed long-read nanopore technology to determine HCMV genome sequences directly from clinical samples. Firstly, I used an Illumina HTS pipeline to sequence HCMV strains directly from formalin-fixed, paraffin-embedded (FFPE) tissues. FFPE samples are a valuable repository for the study of relatively rare diseases, such as congenital HCMV (cCMV). However, formalin fixation induces DNA fragmentation and cross-linking, making this a challenging sample type for DNA sequencing. I successfully sequenced five whole HCMV genomes from FFPE tissues. Next, I developed a pipeline utilising the single-molecule, long-read sequencer from Oxford Nanopore Technologies (ONT) to sequence HCMV initially from high-titre cellcultured laboratory strains and then from clinical samples with high HCMV loads. Finally, I utilised a direct RNA sequencing protocol with the ONT sequencer to characterise novel HCMV transcripts produced during infection in cell culture, demonstrating the existence of transcript isoforms with multiple splice sites. Overall, my findings demonstrate how advanced sequencing technologies can be used to characterise the genome and transcriptome of a large DNA virus, and will facilitate future studies on HCMV prognostic factors, novel antiviral targets and vaccine development.

description: We investigate the fundamental concept of a closed quantum subgroup of a locally compact quantum group. Two definitions - one due to S.Vaes and one due to S.L.Woronowicz - are analyzed and relations between them discussed. Among many reformulations we prove that the former definition can be phrased in terms of quasi-equivalence of representations of quantum groups while the latter can be related to an old definition of Podleś from the theory of compact quantum groups. The cases of classical groups, duals of classical groups, compact and discrete quantum groups are singled out and equivalence of the two definitions is proved in the relevant context. A deep relationship with the quantum group generalization of Herz restriction theorem from classical harmonic analysis is also established, in particular, in the course of our analysis we give a new proof of Herz restriction theorem.

description: Stemformatics (www.stemformatics.org) hosts a collection of curated stem cell focused data, now containing over 400 independent datasets. The capacity to combine these many datasets provides a good representation of the stem cell and blood biology landscape. However, combining data from differing platforms such as Microarrays and RNA Sequencing experiments, poses a significant challenge. The structure of data on each platform is quite different, such as their dynamic range and the characteristics of their noise. We present the results of applying two relatively simple steps – transformation of expression values to percentile values, and the elimination of genes via a univariate estimation of their platform dependence. The impact of platform is nonlinear but it is possible to reveal the biological signal by removal of genes that have a substantial platform dependence. This results in a reduced dimensional space over which new samples can be overlayed.

description: Context Brittle diabetes typically plagues the quality of life of patients after total pancreatectomy. Sparing even a small amount of endocrine tissue avoids extreme glycemic fluctuations, by maintaining a source of servo-regulated endogenous production of all pancreatic hormones (insulin, glucagon, somatostatin and pancreatic polypeptide). Objective We report on the outcome of a selected group of patients undergoing ninety-percent distal pancreatectomy (90% DP). Methods From April 2000 to May 2012, 90% DP was performed in 26 patients: 7 males (27%) and 19 females (73%), with a mean age of 68 years (range 40-79 years). Twenty-three patients underwent conventional open resection while 3 had a laparoscopic operation (robot-assisted in 2 of them). Splenectomy was associated in 24 patients (92%), while 2 had a multivisceral resection. Segmental resection of peripancreatic vessels was associated in 4 patients (1 celiac trunk-hepatic artery, and 3 superior mesenteric/portal vein). Results Seventeen patients were diagnosed with ductal adenocarcinoma (65%), 3 with well-differentiated endocrine tumor (12%), 3 with a serous cystadenoma, 1 with a mucinous cystadenocarcinoma (4%), 1 with carcinoma on IPMN, and 1 patient with chronic pancreatitis. Mean operative-time was 330 minutes (range 180-535 minutes). There was no post-operative mortality with a morbidity of 40%. Pancreatic fistula was recorded in 8 patients (32%) and was always managed conservatively. Thirteen patients developed insulin dependent diabetes mellitus (50%) and 16 developed exocrine insufficiency (61%) requiring enzyme supplementation. Conclusions 90% DP may be considered in patients with centrally located pancreatic lesions to avoid the complications due to pancreatic exocrine and endocrine insufficiency. In selected patients 90% DP may be performed laparoscopically, especially if robotic assistance is available. Careful patient selection and extended experience in pancreatic surgery are crucial to achieve the best results.

description: Context Isolated involvement of an arterial segment in pancreatic tumors occurs infrequently and does not necessarily mean tumor unresctability being possibly caused by tumor location rather than by excessive growth. Objective We report on the outcome of a highly selected group of patients undergoing pancreatectomy plus resection of an isolated arterial segment at a single Institution. Methods From January 1993 to May 2011 resection of an isolated arterial segment was performed during 26 pancreatectomies. There were 12 males (46.2%) and 14 females (53.8%) with a mean age of 63.6 years. One patient was operated by robotic surgery. Two patients underwent total pancreatectomy (7.7%), 5 pancreaticoduodenectomy (19.2%) and 19 distal splenopancreatectomy (73.1%). Resected arterial segments were celiac trunk (CT) (n=14), hepatic artery (HA) (n=8), CT and HA (n=4). In 6 patients the hepatic arterial flow was re-established by end-to-end anastomosis (n=1), transposition of the left gastric artery (n=1) and interposition of a saphenous vein jump-graft (n=4). Multivisceral resection was required in 9 patients. Results Final pathology disclosed ductal adenocarcinoma (DA) in 18 patients (69.2%), other pancreatic tumor types or periampullary carcinoma in 5 (19.2%) patients and metastatic tumor in 3 patients (11.5%). Fifteen DA patients were node positive (83.3%). Post-operative morbidity and mortality were 55.5% and 3.8%, respectively. After a mean follow up period of 111 months (range 5-225 months), actual survival rate was 64% at 1 year and 20% at 3 years. Equivalent figures for DA were 30% and 15%, respectively. These data favorably compare with an historical cohort of patients with locally advanced DA undergoing palliation without resection. No patient developed local recurrence, despite none received pre- or post-operative radiation. Conclusions In patients affected by DA the resection remains key for cure and possibly provides the best palliative treatment. Highly selected patients with isolated involvement of CT and/or HA may undergo pancreatectomy with results similar to patients without vascular involvement and superior to those offered by palliation or medical therapy alone. The lack of local recurrence seems to be a relevant treatment endpoint.
