Abstract
AIMS/HYPOTHESIS The Diabetes Virus Detection (DiViD) study is the first study to laparoscopically collect pancreatic tissue and purified pancreatic islets together with duodenal mucosa, serum, peripheral blood mononuclear cells (PBMCs) and stools from six live adult patients (age 24-35 years) with newly diagnosed type 1 diabetes. The presence of enterovirus (EV) in the pancreatic islets of these patients has previously been reported. METHODS In the present study we used reverse transcription quantitative real-time PCR (RT-qPCR) and sequencing to characterise EV genomes present in different tissues to understand the nature of infection in these individuals. RESULTS All six patients were found to be EV-positive by RT-qPCR in at least one of the tested sample types. Four patients were EV-positive in purified islet culture medium, three in PBMCs, one in duodenal biopsy and two in stool, while serum was EV-negative in all individuals. Sequencing the 5' untranslated region of these EVs suggested that all but one belonged to enterovirus B species. One patient was EV-positive in all these sample types except for serum. Sequence analysis revealed that the virus strain present in the isolated islets of this patient was different from the strain found in other sample types. None of the islet-resident viruses could be isolated using EV-permissive cell lines. CONCLUSIONS/INTERPRETATION EV RNA can be frequently detected in various tissues of patients with type 1 diabetes. At least in some patients, the EV strain in the pancreatic islets may represent a slowly replicating persisting virus.

Abstract
Background Resection margin status is considered one of the few surgeon-controlled parameters affecting prognosis in pancreatic ductal adenocarcinoma (PDAC). While studies mostly focus on resection margins in pancreatoduodenectomy, little is known about their role in distal pancreatectomy (DP). This study aimed to investigate resection margins in DP for PDAC. Methods Patients who underwent DP for PDAC between October 2004 and February 2020 were included (n = 124). Resection margins and associated parameters were studied in two consecutive time periods during which different pathology examination protocols were used: non-standardized (period 1: 2004–2014) and standardized (period 2: 2015–2020). Microscopic margin involvement (R1) was defined as ≤1 mm clearance. Results Laparoscopic and open resections were performed in 117 (94.4%) and 7 (5.6%) patients, respectively. The R1 rate for the entire cohort was 73.4%, increasing from 60.4% in period 1 to 83.1% in period 2 (p = 0.005). A significantly higher R1 rate was observed for the posterior margin (35.8 vs. 70.4%, p < 0.001) and anterior pancreatic surface (based on a 0 mm clearance; 18.9 vs. 35.4%, p = 0.045). Pathology examination period, poorly differentiated PDAC, and vascular invasion were associated with R1 in the multivariable model. Extended DP, positive anterior pancreatic surface, lymph node ratio, perineural invasion, and adjuvant chemotherapy, but not R1, were significant prognostic factors for overall survival in the entire cohort. Conclusions Pathology examination is a key determinant of resection margin status following DP for PDAC. A high R1 rate is to be expected when pathology examination is meticulous and standardized. Involvement of the anterior pancreatic surface affects prognosis. Supplementary Information The online version contains supplementary material available at 10.1245/s10434-021-10464-6.

Abstract
BACKGROUND Laparoscopic distal pancreatectomy (LDP) is advantageous over open surgery in the treatment of benign pancreatic lesions and low-grade malignancies. Yet the evidence on the relationship between comorbidities and the outcomes of LDP remains scarce. METHODS Patients who had undergone LDP for all indications between April 1997 and December 2019 were included. Preoperative physical status was defined according to the American Society of Anesthesiology (ASA) criteria. Perioperative outcomes were compared between the patients with high (ASA III-IV) and low/moderate anesthetic risk (ASA I-II). RESULTS A total of 605 patients were eligible for analysis including 190 with ASA III-IV and 415 with ASA I-II. The former was associated with older age, male gender, preexisting medical conditions, greater total number of comorbidities and red blood cell transfusion. The rate of medical complications was significantly higher in high-risk patients. Multivariable analysis identified ASA III-IV and operative time as independent predictors for medical complications. Overall/severe morbidity, surgical complications and mortality rates were similar. CONCLUSIONS Poor physical status defined as ASA grades III-IV predicts medical complications, but has a limited impact on surgical complications and severe morbidity of LDP. Thus, it should not be considered as a contraindication for LDP.

Abstract
Background Distal pancreatectomy is the most common procedure in minimally-invasive pancreatic surgery. Data in the literature suggest that the learning curve flattens after performing up to 30 procedures. However, the exact number remains unclear. Methods The implementation and training with laparoscopic distal pancreatectomy (LDP) in a high-volume center were studied between 1997 and 2020. Perioperative outcomes and factors related to conversion were assessed. The individual experiences of four different surgeons (pioneer and adopters) performing LDP on a regular basis were examined. Results Six hundred forty LDPs were done accounting for 95% of all distal pancreatectomies performed throughout the study period. Conversion was needed in 14 (2.2%) patients due to intraoperative bleeding or tumor adherence to the major vasculature. Overall morbidity and mortality rates were 35 and 0.6%, respectively. Intra- and postoperative outcomes did not change for any of the surgeons within their first 40 cases. Operative time significantly decreased after the first 80 cases for the pioneer surgeon and did not change afterwards although the proportion of ductal adenocarcinoma increased. Tumor size increased after the first 80 cases for the first adopter without affecting the operative time. Conclusions In this nearly unselected cohort, no significant changes in surgical outcomes were observed throughout the first 40 LDPs for different surgeons. The exact number of procedures required to overcome the learning curve is difficult to determine as it seems to depend on patient selection policy and specifics of surgical training at the corresponding center.

Abstract
BACKGROUND AND PURPOSE Previous abdominal surgery can be a risk factor for perioperative complications in patients undergoing laparoscopic procedures. Today, distal pancreatectomy is increasingly performed laparoscopically. This study investigates the consequences of prior upper abdominal surgery (PUAS) for laparoscopic distal pancreatectomy (LDP). METHODS Patients who had undergone LDP from April 1997 to January 2020 were included. Based on the history and type of PUAS, these were categorized into three groups: minimally invasive (I), open (II), and no PUAS (III). To reduce possible confounding factors, the groups were matched in 1:2:4 fashion based on age, sex, body mass index (BMI) and American Society of Anesthesiology grade. RESULTS After matching, 30, 60, and 120 patients were included in the minimally invasive, open and no PUAS groups, respectively. No statistically significant differences were found in terms of intraoperative outcomes. Postoperative morbidity, mortality and length of hospital stay were similar. Open PUAS was associated with higher Comprehensive Complication Index (33.7 vs 20.9 vs 26.2, p = 0.03) and greater proportion of patients with ≥ 2 complications (16.7 vs 0 vs 6.7%, p = 0.02) compared with minimally invasive and no PUAS. Male sex, overweight (BMI 25-29.9 kg/m2), diagnosis of neuroendocrine neoplasia, and open PUAS were risk factors for severe morbidity in the univariable analysis. Only open PUAS was statistically significant in the multivariable model. CONCLUSIONS PUAS does not impair the feasibility and safety of LDP as its perioperative outcomes are largely comparable to those in patients without PUAS. However, open PUAS increases the burden and severity of postoperative complications.

Abstract
BACKGROUND/OBJECTIVE Pancreatic Cancer Disease Impact (PACADI) score measures the impact of pancreatic cancer (PC) on important health dimensions, selected by patients. The aim of this single center study was to test the psychometric performance of the Pancreatic Cancer Disease Impact (PACADI) score. METHODS Patients with suspected pancreatic cancer (PC) completed PACADI, the EuroQol-5D (EQ-5D index) and Edmonton Symptom Assessment System (ESAS) in this longitudinal observational study. Measures were compared across patients with PC (n = 210), other malignant lesions (OML) (n = 109) and non-malignant lesions (NML) (n = 41). Associations, test-retest and internal consistency reliability, longitudinal changes, sensitivity to change and prediction of mortality during the first year were examined in patients with PC. RESULTS The three measures discriminated between PC and OML. The PACADI score correlated strongly at baseline (n = 199)/after three months (n = 85) with the EQ-5D index and ESAS "sense of well-being" (0.64 and 0.66/0.73 and 0.69, p < 0.001, respectively), showed high test-retest reliability (ICC 0.84) and very good internal consistency reliability (Cronbach's alpha 0.81-0.85) across all visits. Scores improved over time at 3, 6, 9 and 12 months for survivors, and standardized response mean (SRM) for improvement between 2 and 3 months (n = 44) was 0.80 (PACADI), -0.59 (EQ-5D index) and 0.69 (ESAS "sense of well-being"). The PACADI score significantly predicted mortality within the first year (p = 0.02) in contrast to the EQ-5D index and ESAS "sense of well-being". CONCLUSION This study showed satisfactory psychometric performance of the PACADI score. The results support its use in clinical practice and intervention trials.

Abstract
Background: Several guidelines for the management of cystic pancreatic lesions (CPL) exists. From 2013, Oslo University Hospital adapted the European consensus guidelines (ECG) in the decision-making as to whether patients should be advised to have resection or observation for CPL. The aims of the study were to assess changes over time in the workup and diagnostic accuracy of resected CPL, and the short-term surgical outcome. Methods: Preoperative radiological workup, clinicopathological characteristics, and perioperative outcomes were retrospectively reviewed in three consecutive time periods (early: 2004-2008, intermediate: 2009-2012, late: 2013-2016). The rate of concordance between the ECG recommendations for resection (ECG+) or observation (ECG-) and the final histological diagnosis were assessed. Results: A total of 322 consecutive patients underwent resection for CPL (early: n = 89, intermediate: n = 108, late: n = 125). The most common diagnoses were intraductal papillary mucinous neoplasia (IPMN, 36.0%), serous cystic neoplasm (SCN, 23.9%), mucinous cystic neoplasm (10.6%), pseudocyst (9.6%), solid pseudopapillary neoplasm (7.8%), and cystic pancreatic neuroendocrine tumour (5.3%). The proportion of ECG+ CPL undergoing surgery increased significantly (42.7% vs. 60.7% vs. 70.4%, p < .001). The relative proportion of patients undergoing resection for SCN decreased (38.2% vs. 21.3% vs. 16.0%), whereas it increased for IPMN (31.5% vs. 30.6% vs. 44.0%). The use of magnetic resonance imaging and endoscopic ultrasound increased. There were no differences in postoperative severe complications (23.0% vs. 23.6%) or 90-day mortality (2.3% vs. 0.8%) between ECG+ and ECG- patients. Conclusion: Several changes in the management of CPL were revealed during time. Adherence to guidelines is important in order to avoid unnecessary surgery for CPL.

Abstract
BACKGROUND Long-term effects of complications in pancreatic surgery have not been systematically evaluated. The objectives were to assess potential effects of complications on survival and patient reported outcomes (PROs) as well as feasibility of PRO questionnaires in patients with periampullary and pancreatic tumors. METHODS From October 2008 to December 2011, 208 patients undergoing pancreatic surgery were included in a prospective observational study. ESAS, EORTC QLQ-C30 and QLQ-PAN26 questionnaires were completed at inclusion, then every third month. Complications were recorded according to the Clavien-Dindo (CD) classification and Comprehensive Complication Index (CCI). RESULTS 148 complications were registered in 100 patients (48%), 36 patients (17%) had CD IIIa or above. 125 patients (60%) completed baseline questionnaires, 80 (39%) responded after three and 54 (28%) after six months. Complications were associated with reduced long-term survival in patients with pancreatic ductal adenocarcinoma (PDAC) (p = 0.049) and other malignant diseases. No significant relationship was found between complications and PROs, except for anxiety, which was significantly increased in patients with complications. CONCLUSION Postoperative complications led to increased anxiety at 3 months after surgery and were associated with reduced long-term survival in patients with malignancy. A short, patient derived, disease specific questionnaire is required in the clinical research context.

Abstract
The laparoscopic technique in distal pancreatic resection (LDP) has been widely accepted, and outcome data support the hypothesis that survival is improved, partly due to improved postoperative safety and recovery, thus optimizing treatment with adjuvant chemotherapy. But laparoscopic pancreaticoduodenectomy (LPD or Whipple-procedures) has spread more slowly, due to the complexity of the procedure. Surgical safety has been a problem in hospitals with low patient volume, resulting in raised postoperative mortality, requiring careful monitoring of outcome during the surgical learning curve. Robotic assistance is expected to improve surgical safety, but data on long term oncological outcome of laparoscopic Whipple procedures with or without robotic assistance is scarce. Future research should still focus surgical safety, but most importantly long term outcome, recorded as recurrence at maximal follow up or - at best - overall long term survival (OS). Available data show median survival above 2.5 years, five year OS more than 30% after LDP even in series with suboptimal adjuvant chemotherapy. Also after LPD, long term survival is reported equal to or longer than open resection. However, surgical safety during the learning curve of LPD is a problem, which hopefully can be facilitated by robotic assistance. Patient reported outcome should also be an endpoint in future trials, including patients with pancreatic ductal adenocarcinoma.

Abstract
BACKGROUND Lymph node yield (LNY) is an indicator of oncological adequacy of surgery in patients with pancreatic ductal adenocarcinoma (PDAC). Our hypothesis is that standardized pathology examination (SPE) aimed at accurate staging can increase the LNY without changing surgical technique. METHODS After the introduction of SPE for distal pancreatosplenectomy specimens at Oslo University Hospital, prospective data were collected on patients with PDAC undergoing laparoscopic distal pancreatosplenectomy (LDP). Their data were compared with retrospective data from specimens examined in a non-standardized way (NSPE). RESULTS SPE and NSPE were applied to 20 and 33 specimens, respectively. SPE was associated with a higher LNY and a higher median number of positive lymph nodes (PLN) in the specimen (18 vs 7, P = 0.001 and 4 vs 1, P = 0.005, respectively). In the stepwise regression model, SPE and younger age resulted in an increased LNY. In the logistic regression model, increased LNY and larger tumor size positively correlated with the presence of PLN. CONCLUSION SPE of distal pancreatosplenectomy specimens is associated with higher LNY in patients with PDAC, which increases the likelihood of detecting PLN and reduces the risk of understaging. These findings also indicate that the LDP technique provides an adequate LNY in patients with PDAC.

Abstract
BACKGROUND Surgical resection is the only curative option in patients with pancreatic ductal adenocarcinoma. Little is known about the oncologic outcomes of laparoscopic distal pancreatectomy. This bi-institutional study aimed to examine the long-term oncologic results of standard laparoscopic distal pancreatectomy in a large cohort of patients with pancreatic ductal adenocarcinoma. METHODS From January 2002 to March 2016, 207 patients underwent standard laparoscopic distal pancreatectomy for pancreatic ductal adenocarcinoma at Oslo University Hospital-Rikshospitalet (Oslo, Norway) and Asan Medical Centre (Seoul, Republic of Korea). After the exclusion criteria were applied (distant metastases at operation, conversion to an open operation, loss to follow-up), 186 patients were eligible for the analysis. Perioperative and oncologic variables were analyzed for association with recurrence and survival. RESULTS Median overall and recurrence-free survivals were 32 and 16 months, while 5-year overall and recurrence-free survival rates were estimated to be 38.2% and 35.9%, respectively. Ninety-six (52%) patients developed recurrence: 56 (30%) extrapancreatic, 27 (15%) locoregional, and 13 (7%) combined locoregional and extrapancreatic. Thirty-seven (19.9%) patients had early recurrence (within 6 months of operation). In the multivariable analysis, tumor size >3 cm and no adjuvant chemotherapy were associated with early recurrence (P = .017 and P = .015, respectively). The Cox regression model showed that tumor size >3 cm and lymphovascular invasion were independent predictors of decreased recurrence-free and overall survival. CONCLUSION Standard laparoscopic distal pancreatectomy is associated with satisfactory long-term oncologic outcomes in patients with pancreatic ductal adenocarcinoma. Several risk factors, such as tumor size >3 cm, no adjuvant chemotherapy, and lymphovascular invasion, are linked to poor prognosis after standard laparoscopic distal pancreatectomy.

Abstract
Treatment of pancreatic cancer is multimodal and surgery is an essential part, mandatory for curative potential. Also chemotherapy is essential, and serious postoperative complications or rapid disease progression may preclude completion of multimodal treatment. The sequence of treatment interventions has therefore become an important concern, and numerous ongoing randomized controlled trials compare clinical outcome after upfront surgery and neoadjuvant treatment with subsequent resection. In previous years, borderline resectable and locally advanced pancreatic cancer was most often considered unresectable. More effective chemotherapy together with the latest improvements in surgical expertise has resulted in extended operations, pushing the borders of resectability. Multivisceral resections with or without resection of major mesenteric vessels are now performed in numerous patients, resulting in better outcome, recorded as overall survival and/or patient reported outcome. But postoperative morbidity increases concurrently, and clinical benefit must be carefully evaluated against risk of potential harm, associated with new comprehensive multimodal treatment sequences. Even though cost/utility analyses are deficient, extended surgery has resulted in significantly longer and better life for many patients with no other treatment alternative. Improved selection of patients to surgery and/or chemotherapy will in the near future be possible, based on better tumor biology insight. Clinically available biomarkers enabling personalized treatment are forthcoming, but these options are still limited. The importance of surgical resection for each patient’s prognosis is presently increasing, justifying sustained expansion of the surgical treatment modality.

Abstract
Chemotherapy with improved effect in patients with metastatic pancreatic cancer has recently been established, launching a new era for patients with this very aggressive disease. FOLFIRINOX and gemcitabine plus nab-paclitaxel are different regimens, both capable of stabilizing the disease, thus increasing the number of patients who can reach second line and even third line of treatment. Concurrently, new windows of opportunity open for nutritional support and other therapeutic interventions, improving quality of life. Also pancreatic surgery has changed significantly during the latest years. Extended operations, including vascular/multivisceral resections are frequently performed in specialized centers, pushing borders of resectability. Potentially curative treatment including neoadjuvant and adjuvant chemotherapy is offered new patient groups. Translational research is the basis for the essential understanding of the ongoing development. Even thou biomarkers for clinical management of patients with periampullary tumors have almost been lacking, biomarker driven trials are now in progress. New insight is constantly made available for clinicians; one recent example is selection of patients for gemcitabine treatment based on the expression level of the human equilibrium nucleoside transporter 1. An example of new diagnostic tools is identification of early pancreatic cancer patients by a three-biomarker panel in urine: The proteins lymphatic vessel endothelial hyaluronan receptor 1, regenerating gene 1 alpha and translation elongation factor 1 alpha. Requirement of treatment guideline revisions is intensifying, as combined chemotherapy regimens result in unexpected advantages. The European Study Group for Pancreatic Cancer 4 trial outcome is an illustration: Addition of capecitabine in the adjuvant setting improved overall survival more than expected from the effect in advanced disease. Rapid implementation of new treatment options is mandatory when progress finally extends to patients with this serious disease.

Abstract
Despite advances in diagnostics, less than 5% of patients with periampullary tumors experience an overall survival of five years or more. Periampullary tumors are neoplasms that arise in the vicinity of the ampulla of Vater, an enlargement of liver and pancreas ducts where they join and enter the small intestine. In this study, we analyzed copy number aberrations using Affymetrix SNP 6.0 arrays in 60 periampullary adenocarcinomas from Oslo University Hospital to identify genome-wide copy number aberrations, putative driver genes, deregulated pathways, and potential prognostic markers. Results were validated in a separate cohort derived from The Cancer Genome Atlas Consortium (n = 127). In contrast to many other solid tumors, periampullary adenocarcinomas exhibited more frequent genomic deletions than gains. Genes in the frequently codeleted region 17p13 and 18q21/22 were associated with cell cycle, apoptosis, and p53 and Wnt signaling. By integrating genomics and transcriptomics data from the same patients, we identified CCNE1 and ERBB2 as candidate driver genes. Morphologic subtypes of periampullary adenocarcinomas (i.e., pancreatobiliary or intestinal) harbor many common genomic aberrations. However, gain of 13q and 3q, and deletions of 5q were found specific to the intestinal subtype. Our study also implicated the use of the PAM50 classifier in identifying a subgroup of patients with a high proliferation rate, which had impaired survival. Furthermore, gain of 18p11 (18p11.21-23, 18p11.31-32) and 19q13 (19q13.2, 19q13.31-32) and subsequent overexpression of the genes in these loci were associated with impaired survival. Our work identifies potential prognostic markers for periampullary tumors, the genetic characterization of which has lagged. Cancer Res; 76(17); 5092-102. ©2016 AACR.

Abstract
BACKGROUND The purpose of this prospective study was to evaluate whether pre-surgery health-related quality of life (HRQoL) and subjectively rated symptom scores are prognostic factors for survival in patients with resectable pancreatic ductal adenocarcinoma (PDAC). METHODS Patients undergoing pancreatic resection for PDAC completed the Edmonton Symptom Assessment System (ESAS) and the EORTC QLQ-C30 and QLQ-PAN26 questionnaires preoperatively. Patient, tumor and treatment characteristics, recurrence and survival were registered. RESULTS Sixty-six consecutive patients underwent R0/R1 resection for PDAC. Baseline ESAS and EORTC questionnaire compliance was 44/66 (67%) with no statistically significant differences between compliers (n = 44) and non-compliers (n = 22) when comparing clinicopathological parameters and survival. Univariable analyses showed that three symptoms (nausea, dry mouth, cognitive function) and two clinicopathological factors (CA 19-9 > 400 U/ml, lymph node ratio > 0.1) were significantly associated with shorter survival (p < 0.05). In multivariable analysis, cognitive function was the only independent predictor for survival: hazard ratio = 0.35 (95%CI 0.13-0.93) for high vs low cognitive function. Median survival times for patients with high and low cognitive function were 21 and 10 months, respectively (p < 0.001). CONCLUSION Presurgery cognitive function is a significant independent predictor of survival in patients with resectable PDAC. Thus, presurgery patient reported outcomes may provide as strong prognostic information as clinicopathological factors.

Abstract
AIMS/HYPOTHESIS It is thought that T cells play a major role in the immune-mediated destruction of beta cells in type 1 diabetes, causing inflammation of the islets of Langerhans (insulitis). The significance of insulitis at the onset of type 1 diabetes is debated, and the role of the T cells poorly understood. METHODS In the Diabetes Virus Detection (DiViD) study, pancreatic tissue from six living patients with recent-onset type 1 diabetes was collected. The insulitis was characterised quantitatively by counting CD3(+) T cells, and qualitatively by transcriptome analysis targeting 84 T and B lymphocyte genes of laser-captured microdissected islets. The findings were compared with gene expression in T cells collected from kidney biopsies from allografts with ongoing cellular rejection. Cytokine and chemokine release from isolated islets was characterised and compared with that from islets from non-diabetic organ donors. RESULTS All six patients fulfilled the criteria for insulitis (5-58% of the insulin-containing islets in the six patients had ≥ 15 T cells/islet). Of all the islets, 36% contained insulin, with several resembling completely normal islets. The majority (61-83%) of T cells were found as peri-insulitis rather than within the islet parenchyma. The expression pattern of T cell genes was found to be markedly different in islets compared with the rejected kidneys. The islet-infiltrating T cells showed only background levels of cytokine/chemokine release in vitro. CONCLUSIONS/INTERPRETATION Insulitis and a significant reserve reservoir for insulin production were present in all six cases of recent-onset type 1 diabetes. Furthermore, the expression patterns and levels of cytokines argue for a different role of the T cells in type 1 diabetes when compared with allograft rejection.

Abstract
Periampullary adenocarcinomas can be of two histological subtypes, intestinal or pancreatobiliary. The latter is more frequent and aggressive, and characterized by a prominent desmoplastic stroma, which is tightly related to the biology of the cancer, including its poor response to chemotherapy. Whereas miRNAs are known to regulate various cellular processes and interactions between cells, their exact role in periampullary carcinoma remains to be characterized, especially with respect to the prominent stromal component of pancreatobiliary type cancers. The present study aimed at elucidating this role by miRNA expression profiling of the carcinomatous and stromal component in twenty periampullary adenocarcinomas of pancreatobiliary type. miRNA expression profiles were compared between carcinoma cells, stromal cells and normal tissue samples. A total of 43 miRNAs were found to be differentially expressed between carcinoma and stroma of which 11 belong to three miRNA families (miR-17, miR-15 and miR-515). The levels of expression of miRNAs miR-17, miR-20a, miR-20b, miR-223, miR-10b, miR-2964a and miR-342 were observed to be higher and miR-519e to be lower in the stromal component compared to the carcinomatous and normal components. They follow a trend where expression in stroma is highest followed by carcinoma and then normal tissue. Pathway analysis revealed that pathways regulating tumor-stroma interactions such as ECM interaction remodeling, epithelial-mesenchymal transition, focal adhesion pathway, TGF-beta, MAPK signaling, axon guidance and endocytosis were differently regulated. The miRNA-mRNA mediated interactions between carcinoma and stromal cells add new knowledge regarding tumor-stroma interactions.

Abstract
BACKGROUND Laparoscopy is widely accepted as a feasible option for distal pancreatectomy. However, the experience in laparoscopic distal pancreatectomy (LDP) for pancreatic ductal adenocarcinoma (PDAC) is limited to a small number of studies, reported by expert centers. The present study aimed to evaluate perioperative and oncological outcomes after LDP for PDAC in a large, multicenter cohort of patients. METHODS A retrospective analysis of the data on 196 patients with histologically verified PDAC, operated at Oslo University Hospital-Rikshospitalet (Oslo, Norway), Asan Medical Center (Seoul, Republic of Korea), Institut Mutualiste Montsouris (Paris, France) and University Hospital Southampton (Southampton, UK) between January 2002 and April 2015 was conducted. The patients with standard (SLDP) and extended (i.e., en bloc with adjacent organ, ELDP) resections were compared in terms of perioperative and oncological outcomes. RESULTS Out of 196 LDP procedures, 191 (97.4 %) were completed through laparoscopy, while five (2.6 %) were converted to open surgery. ELDP was performed in 30 (15.7 %) cases. Sixty-one (31.9 %) patients experienced postoperative complications, including 48 (25.1 %) with pancreatic fistula. The rate of clinically relevant fistula (grade B/C) was 15.7 %. Median postoperative hospital stay was 8 (2-63) days. Median follow-up was 16 months. Median survival was 31.3 months (95 % CI 22.9-39.6). Three- and 5-year actuarial survival rates were 42.4 and 30 %, respectively. SLDP was associated with significantly higher survival compared with ELDP (p = 0.032). CONCLUSIONS LDP seems to be a feasible and safe procedure, providing satisfactory oncological outcomes in patients with PDAC.

Abstract
The cause of type 1 diabetes remains unknown. To dissect the link between hyperexpression of human leukocyte antigen (HLA) class I on the islet cells, we examined its expression in subjects with recent-onset type 1 diabetes. IHC showed seemingly pronounced hyperexpression in subjects with recent-onset type 1 diabetes, as well as in some nondiabetic subjects. In all subjects, HLA class I expression on exocrine tissue was low. However, no difference in the level of HLA class I expression was found between islet and exocrine tissue using Western blot, flow cytometry, real-time quantitative PCR, or RNA sequencing analyses. Also, the level of HLA class I expression on the messenger level was not increased in islets from subjects with recent-onset type 1 diabetes compared with that in nondiabetic subjects. Consistently, the HLA class I specific enhanceosome (NLRC5) and related transcription factors, as well as interferons, were not enhanced in islets from recent-onset type 1 diabetic subjects. In conclusion, a discrepancy in HLA class I expression in islets assessed by IHC was observed compared with that using quantitative techniques showing similar expression of HLA class I in islets and exocrine tissue in subjects with recent-onset type 1 diabetes, nor could any differences be found between type 1 diabetic and nondiabetic subjects. Results presented provide important clues for a better understanding on how this complex disease develops.

Abstract
BACKGROUND Multimodality treatment (MMT) improves survival for patients with pancreatic ductal adenocarcinoma (PDAC). The surgery-first (SF) strategy is the most universally accepted approach. MATERIAL AND METHODS Population-based retrospective cohort study of all cases of resectable PDAC from 2006 to 2012. Patients were planned for adjuvant chemotherapy (AC) with the Nordic 5-fluorouracil/leucovorin regimen. Reasons for and rates of failure to complete AC, postoperative major complications (PMC), and overall survival (OS) were analysed. RESULTS Of 203 patients, 85 (41.9%) completed AC, 41 (20.2%) failed to complete AC, and 77 (37.9%) never initiated AC. Primary reasons for not initiating or completing AC were early disease progression (34.7%), postoperative complications/poor performance status (32.2%), and age > 75 years (24.6%). Median OS in the whole cohort was 17.0 months, and 20.0 months in patients who initiated AC. Median OS in patients who completed AC was higher than in patients who did not (25.0 months vs. 12.0 months, p < 0.001). PMC (n = 41) were associated with decreased initiation rate (p < 0.001) and completion rate (p = 0.007) of AC, and decreased median OS (11.0 months vs. 19.0 months, p = 0.028). Among patients with R1 resection, PMC again were associated with worse median OS (8.0 months vs. 16.0 months, p = 0.028). Multivariate analysis demonstrated that completion of MMT and tumour grade (G1/G2) were related to mortality rate (p < 0.001). Mortality risk for patients who completed AC was reduced also when adjusting for competing risk (SHR 0.426, p < 0.001). CONCLUSIONS MMT completion is strongly associated with reduced mortality risk in patients with resectable PDAC undergoing the SF approach. Early disease progression and PMC/poor performance status preclude MMT completion in more than one third of the patients. These reasons for failure to complete MMT underscore the need for strategies to improve patient selection and reduce surgical morbidity in patients with resectable PDAC.

Abstract
The understanding of the etiology of type 1 diabetes (T1D) remains limited. One objective of the Diabetes Virus Detection (DiViD) study was to collect pancreatic tissue from living subjects shortly after the diagnosis of T1D. Here we report the insulin secretion ability by in vitro glucose perifusion and explore the expression of insulin pathway genes in isolated islets of Langerhans from these patients. Whole-genome RNA sequencing was performed on islets from six DiViD study patients and two organ donors who died at the onset of T1D, and the findings were compared with those from three nondiabetic organ donors. All human transcripts involved in the insulin pathway were present in the islets at the onset of T1D. Glucose-induced insulin secretion was present in some patients at the onset of T1D, and a perfectly normalized biphasic insulin release was obtained after some days in a nondiabetogenic environment in vitro. This indicates that the potential for endogenous insulin production is good, which could be taken advantage of if the disease process was reversed at diagnosis.

Abstract
The Diabetes Virus Detection study (DiViD) is the first to examine fresh pancreatic tissue at the diagnosis of type 1 diabetes for the presence of viruses. Minimal pancreatic tail resection was performed 3-9 weeks after onset of type 1 diabetes in six adult patients (age 24-35 years). The presence of enteroviral capsid protein 1 (VP1) and the expression of class I HLA were investigated by immunohistochemistry. Enterovirus RNA was analyzed from isolated pancreatic islets and from fresh-frozen whole pancreatic tissue using PCR and sequencing. Nondiabetic organ donors served as controls. VP1 was detected in the islets of all type 1 diabetic patients (two of nine controls). Hyperexpression of class I HLA molecules was found in the islets of all patients (one of nine controls). Enterovirus-specific RNA sequences were detected in four of six patients (zero of six controls). The results were confirmed in various laboratories. Only 1.7% of the islets contained VP1(+) cells, and the amount of enterovirus RNA was low. The results provide evidence for the presence of enterovirus in pancreatic islets of type 1 diabetic patients, which is consistent with the possibility that a low-grade enteroviral infection in the pancreatic islets contributes to disease progression in humans.

Abstract
Periampullary adenocarcinomas include four anatomical sites of origin (the pancreatic duct, bile duct, ampulla and duodenum) and most of them fall into two histological subgroups (pancreatobiliary and intestinal). Determining the exact origin of the tumor is sometimes difficult, due to overlapping histopathological characteristics. The prognosis depends on the histological subtype, as well as on the anatomical site of origin, the former being the more important. The molecular basis for these differences in prognosis is poorly understood. Whole-genome analyses were used to investigate the association between molecular tumor profiles, pathogenesis and prognosis. A total of 85 periampullary adenocarcinomas were characterized by mRNA and miRNA expressions profiling. Molecular profiles of the tumors from the different anatomical sites of origin as well as of the different histological subtypes were compared. Differentially expressed mRNAs and miRNAs between the two histopathological subtypes were linked to specific molecular pathways. Six miRNA families were downregulated and four were upregulated in the pancreatobiliary type as compared to the intestinal type (P < 0.05). miRNAs and mRNAs associated with improved overall and recurrence free survival for the two histopathological subtypes were identified. For the pancreatobiliary type the genes ATM, PTEN, RB1 and the miRNAs miR-592 and miR-497, and for the intestinal type the genes PDPK1, PIK3R2, G6PC and the miRNAs miR-127-3p, miR-377* were linked to enriched pathways and identified as prognostic markers. The molecular signatures identified may in the future guide the clinicians in the therapeutic decision making to an individualized treatment, if confirmed in other larger datasets.

Abstract
Pancreatic adenocarcinoma is one of the most aggressive cancers, and the decline in mortality observed in most other cancer diseases, has so far not taken place in pancreatic cancer. Complete tumor resection is a requirement for potential cure, and the reorganization of care in the direction of high patient-volume centers, offering multimodal treatment, has improved survival and Quality of Life. Also the rates and severity grade of complications are improving in high-volume pancreatic centers. One of the major problems worldwide is underutilization of surgery in resectable pancreatic cancer. Suboptimal investigation, follow up and oncological treatment outside specialized centers are additional key problems. New chemotherapeutic regimens like FOLFIRINOX have improved survival in patients with metastatic disease, and different adjuvant treatment options result in well documented survival benefit. Neoadjuvant treatment is highly relevant, but needs further evaluation. Also adjuvant immunotherapy, in the form of vaccination with synthetic K-Ras-peptides, has been shown to produce long term immunological memory in cytotoxic T-cells in long term survivors. Improvement in clinical outcome is already achievable and further progress is expected in the near future for patients treated with curative as well as palliative intention.

Abstract
Abstract Objective. The first objective of the present study was to identify opportunities of improvement for clinical practice, assessed by local quality indicators, then to analyze possible reasons why we did not reach defined treatment quality measures. The second objective was to characterize patients, considered unresectable according to present criteria, for future arrangement of interventional studies with improved patient selection. Material and methods. Prospective observational cohort study from October 2008 to December 2010 of patients referred to the authors' institution with suspected pancreatic or periampullary neoplasm. Results. Of 330 patients, 135 underwent surgery, 195 did not, 129 due to unresectable malignancies. The rest had benign lesions. Perioperative morbidity rate was 32.6%, mortality 0.7%. Radical resection (R0) was obtained in 23 (41.8%) of 55 patients operated for pancreatic adenocarcinoma and 6.3% underwent reconstructive vascular surgery. Diagnostic failure/delay resulted in unresectable carcinoma, primarily misconceived as serous cystic adenoma in two patients. One resected lesion turned out to be focal autoimmune pancreatitis. One case with misdiagnosed cancer was revised to be a pseudoaneurysm. Palliative treatment was offered to 144 patients with malignant tumors, 62 due to locally advanced disease and all pancreatic adenocarcinomas. Conclusions. Quality improvement opportunities were identified for patient selection and surgical technique: Too few patients underwent reconstructive vascular surgery. The most important quality indicators are those securing resectional, radical (R0) surgery. Altogether 143 patients (57.9%) of those with malignant tumors were found unresectable, most of these patients are eligible for inclusion in future interventional studies with curative and/or palliative intention.

Abstract
AIM There is no consensus on the optimal follow-up schedule of patients after surgery for pancreatic cancer. In this retrospective study, recurrence and survival were investigated for patients presenting with either symptomatic or asymptomatic recurrence. Patient, tumor and treatment characteristics that predicted the length of postrecurrence survival were identified. METHODS Clinical records of 164 patients who underwent a pancreatic resection (R0/R1) for pancreatic ductal adenocarcinoma from January 2000 to December 2010 were retrieved. Patients underwent a systematic follow-up program. Patient, tumor and treatment characteristics were compared between patients with asymptomatic and symptomatic recurrence. RESULTS Of 164 consecutive patients, 144 patients (88%) had recurrence (29 asymptomatic, 115 symptomatic). The most frequent reported symptoms were abdominal pain, fatigue/weakness, back pain, weight loss, nausea/loss of appetite and jaundice. Median time to recurrence was 12.0 months for asymptomatic and 7.0 months for symptomatic patients (P = 0.036). Median postrecurrence survival was 10.0 months for asymptomatic and 4.0 months for symptomatic patients (P < 0.0001). Median overall survival was 24.5 months for asymptomatic and 11.0 months for symptomatic patients (P < 0.0001). Symptomatic recurrence, disease free survival <12 months, and no adjuvant chemotherapy were the only independent predictors of poor postrecurrence survival. 72% of asymptomatic and 37% of symptomatic patients received oncological treatment. CONCLUSIONS Patients with asymptomatic pancreatic cancer recurrence have improved recurrence-free, postrecurrence and overall survival. Symptoms when recurrence is diagnosed are a good surrogate marker of biological aggressiveness. Detection of asymptomatic recurrence may facilitate patient eligibility for investigational studies or other forms of treatment.

Abstract
OBJECTIVE To prospectively record the clinical consequences of R1 resection of pancreatic adenocarcinoma compared to patients with locally advanced tumours not undergoing surgery. BACKGROUND Surgery is the only potentially curative treatment of pancreatic cancer, and postoperative safety is increasing. The rate of R1 resections might also increase unintentionally as surgical procedures with curative goal become more comprehensive, and the clinical outcome requires further prospective evaluation. MATERIAL AND METHODS Prospective observational cohort study from October 2008 to December 2010. Outcome after R1 resection (group 1, surgery, n = 32) and conservative palliative chemoradiation/endoscopy (group 2, no surgery, n = 56) is compared with survival and longitudinal patient-reported quality of life (QoL) as endpoints. QoL was assessed by the Edmonton Symptom Assessment System (ESAS). RESULTS Demographic characteristics and tumour diameters were similar in both groups: 38.0 (31.3, 49.8) mm in group 1 versus 44.0 (39.6, 49.1) mm in group 2 (p = 0.18). Perioperative morbidity was 25% with no mortality. Disease-specific survival was 18.0 (14.5, 23.8) months in group 1 versus 8.1 (4.8, 10.1) months in group 2 (p < 0.0001). Overall survival was 11 (7.8, 14.4) months. Reduction in fatigue was significantly improved in the surgery group 6, 12, and 19 weeks after baseline, whereas reduction in global health was significantly better in group 2. CONCLUSION Radical removal (R0 resection) is the primary aim of surgery, but also R1 resection seems to improve survival and QoL, compared to outcome in patients with locally advanced tumours not undergoing surgery.

Abstract
OBJECTIVE Patient-reported outcomes are important for clinical practice and research, and should reflect what patients perceive as important. The objective of this study was to develop and preliminarily validate a brief, patient-derived, disease-specific tool, the pancreatic cancer disease impact (PACADI) score. METHODS The development was performed in two phases. Forty-one patients with confirmed pancreatic cancer (PC) selected dimensions of health related to the impact of the disease. A weighting of the eight most frequently reported dimensions was performed in a second sample of 80 PC patients who also rated the impact on eight numeric rating scales (NRS, range 0 to 10). The relative weights and the scores from the NRS were used to compute the PACADI score (range 0 to 10). The patients also completed Edmonton Symptom Assessment System (ESAS) and EQ-5D. RESULTS Dimensions reported by more than 20% of the patients were included in the PACADI score (relative weights in parenthesis): pain/discomfort (0.16), fatigue (0.16), anxiety (0.15), bowel/digestive problems (0.14), loss of appetite (0.13), dry mouth (0.11), itchiness (0.08), and nausea (0.07). The PACADI score in the 80 PC patients had a mean (SD) value of 3.26 (2.06) (95% CI 2.80, 3.71), was moderately to strongly correlated to ESAS sense of well-being (r = 0.69) and EQ-5D (r = -0.52), and discriminated significantly between patients with and without PC. CONCLUSION The PACADI score is a new eight-item, patient-derived, disease-specific measure. Preliminary validation regarding construct validity and discrimination encourages further validation in independent patient samples.

Abstract
Endometrial cyst of the pancreas was first described in 1984. The condition is extremely rare, and only a few case reports have been described. Herein we present a case report of a peripancreatic endometriosis cyst in a perimenopausal woman. Computed tomography, magnetic resonance imaging, and regression of the cyst during an observation period of a few months made the diagnosis most likely before laparoscopic surgery. Awareness of the condition, optimal preoperative imaging, and clinical features are discussed.

Abstract
BACKGROUND The role of laparoscopic resection in patients with pancreatic cancer remains to be clarified, because previous reports have not clearly defined oncologic outcomes. The objective of the present study was to investigate this question with the rate of R0 resection and long-term survival as endpoints. METHODS This retrospective observational study included prospectively collected data from 40 patients operated laparoscopically with curative intent for exocrine pancreatic malignancies identified among 250 consecutive patients undergoing laparoscopic pancreatic operations since 1997. All 40 patients had histologically verified exocrine pancreatic carcinoma. RESULTS Ten patients (25%) with typical ductal adenocarcinoma of the pancreas were deemed nonresectable by laparoscopic staging. Laparoscopic distal pancreatectomy was performed in 29 patients; 8 resections were combined with resections of adjacent organs and 1 removal of a malignant intraductal papillary mucinous neoplasm what appeared to be ectopic pancreatic tissue. In 1 patient, the resection was completed by hand-assisted technique, and 1 procedure was converted to open resection. Postoperative morbidity was 23% (n = 7). The median hospital stay was 5 days (range, 1-30). The rate of R0 resections was 93%. Postoperative 3-year survivals rates were 36% for the entire cohort (n = 30) and 30% in typical ductal adenocarcinoma (n = 21). CONCLUSION Laparoscopic distal pancreatectomy for exocrine pancreatic carcinoma is comparable with outcomes after open surgery and supports the concept that laparoscopic distal pancreatectomy is a safe, oncologic procedure.

Abstract
Loss of adipose tissue in patients with pancreatic cancer may involve altered gene expression. Peri-operative mRNA levels of 44 genes were analysed by RT-PCR in intra-abdominal (IAAT) and subcutaneous adipose tissue (SCAT) sampled from pancreatic ductal adenocarcinoma (PDAC) patients undergoing tumour resection (n = 20), and control patients without cancer (n = 11). Peri- and post-operative IAAT and SCAT masses were measured by computerized tomography. PDAC patients displayed 2.6- and 1.7-fold higher Zn-α2-glycoprotein (AZGP1) mRNA levels than controls in IAAT and SCAT, respectively (P < 0.01), but expression was not correlated with post-operative changes in fat masses. IAAT mass changes correlated with genes in lipid metabolism, inflammation and apoptosis: e.g. stearoyl-Coenzyme A desaturase 1 (SCD), tumour necrosis factor (TNF) and chemokine (C-C motif) ligand 2 (CCL2; MCP-1). Patients with PDAC displayed increased AZGP1 mRNA levels in both IAAT and SCAT, but expression of other genes may predict IAAT loss.

Abstract
BACKGROUND Laparoscopic resection is regarded as safe and feasible in selected patients with benign pancreatic tumours. Few data exist on laparoscopic surgery for malignant lesions and larger neoplasms in unselected patients. METHODS The study included all patients admitted to Oslo University Hospital, Rikshospitalet, from March 1997 to March 2009 for surgery of lesions in the body and tail of the pancreas, and selected patients with lesions in the pancreatic head, who underwent surgery by a laparoscopic approach with curative intent. RESULTS A total of 166 patients had 170 operations, including 138 pancreatic resections, 18 explorations, nine resections of peripancreatic tissue and five other therapeutic procedures. Four patients had repeat procedures. There were 53 endocrine tumours (31.0 per cent), 28 pancreatic carcinomas (16.4 per cent), five cases of metastases (2.9 per cent), 48 cystic tumours (28.1 per cent) and 37 other lesions (21.6 per cent). The total morbidity rate was 16.5 per cent. Fistula was the most common complication (10.0 per cent). Three patients needed reoperation for complications. There were three hospital deaths (1.8 per cent). Median hospital stay following surgery was 4 days. CONCLUSION Laparoscopic resection of lesions in the body and tail of the pancreas in an unselected patient series was safe and feasible, and should be the method of choice for this patient group in specialized centres.

Abstract
We report four patients with pancreatic fistulas that failed to respond to conservative treatment. The fistulas were closed by endoscopic injection of N-butyl-2-cyanoacrylate (Histoacryl) diluted with an oily contrast agent (Lipiodol). A literature review revealed 32 similar cases in which endoscopic treatment with fibrin sealants (n = 11) or cyanoacrylate (n = 21) was used to close the fistulas. Based on our own experience and the literature review, we conclude that endoscopic sealing of pancreatic fistulas can be performed safely and effectively by experienced endoscopists in a tertiary centre. The procedure seems useful in the management of complicated pancreatic fistulas which do not respond to conservative treatment and may obviate the need for surgery.

Abstract
OBJECTIVE We hypothesised that a formal treatment protocol for liver injuries including angiography would increase the non-operative management (NOM) rate and would be efficient as an adjunct to damage control surgery. METHODS During the 4-year period from 1 August 2000, a total of 138 adult patients with liver injuries were admitted to the largest trauma centre in Norway and prospectively included in the institutional trauma registry. On 1 August 2002, a protocol mandating angiography in all NOM patients with OIS grades 3-5 liver injuries and after packing of the liver was implemented. All patients admitted during the subsequent 2-year period (group 2) were compared with the previous 2 years as historic controls (group 1). RESULTS Fifty-five patients were included in group 1 and 59 in group 2. The groups were statistically comparable, both with a mean ISS of 31. Patients selected for NOM increased from 28 (51%) to 45 (76%) (p<0.05), without increasing failure rate, liver-related complications, mortality or transfusion rate. Angiography was performed in 26 patients in group 2 (44%). Only nine patients underwent embolisation (35%), and five of these were in the NOM group. Angiography was negative in the eight NOM stable patients with OIS grade 3 injury. CONCLUSION The implementation of a formal NOM protocol decreased total laparotomy rate and seemed to improve patient outcome without jeopardising patient safety. Surprisingly few of the patients undergoing angiography required embolisation. Angiography is not indicated in stable OIS grade 3 liver injuries, and the protocol in our institution has been adjusted accordingly. AE seems to be a valuable adjunct to DCS with packing of liver injuries.

Abstract
PURPOSE To explore the usefulness of secretin-stimulated magnetic resonance cholangiopancreatography (S-MRCP) on different pathological entities in the pancreaticobiliary tract (PBT) MATERIAL AND METHODS: Sixty-two patients with unclear disease in the PBT were examined with S-MRCP as the final radiological procedure. Nine groups of referral diagnoses were identified, and clinical outcome was evaluated. RESULTS In five patients with suspected pancreatic duct injury after blunt abdominal trauma, a negative predictive value of 100% was found after a median of 3.5 months of follow-up. In 22 patients with residual pain after cholecystectomy, investigated for sphincter of Oddi dysfunction (SOD), delayed dilatation of the PD and pain were documented in four patients. Three of these were treated with endoscopic papillotomy (EPT), and no recurrences were found during an average of 13.6 months of follow-up. Five cases of pancreas divisum not previously seen were identified, and of 12 patients with suspected postoperative stenosis, five were successfully treated after being identified with S-MRCP. Useful information was obtained in most of the patients, i.e., findings not observed in previous radiological examinations or clarifying uncertain previous findings. Nine patients were referred to other non-radiological examinations, identifying that the origin of disease was outside the PBT. CONCLUSION S-MRCP has the potential to become the final part of diagnostic workup in difficult PBT diseases, but further investigation of usefulness regarding different referral reasons is mandatory.

Abstract
Patients with inoperable pancreatic cancer have a dismal prognosis with a mean life expectancy of 3–6 months. New treatment modalities are thus urgently needed. Telomerase is expressed in 85–90% of pancreas cancer, and immunogenic telomerase peptides have been characterised. A phase I/II study was conducted to investigate the safety, tolerability, and immunogenecity of telomerase peptide vaccination. Survival of the patients was also recorded. Forty-eight patients with non-resectable pancreatic cancer received intradermal injections of the telomerase peptide GV1001 at three dose levels, in combination with granulocyte–macrophage colony-stimulating factor. The treatment period was 10 weeks. Monthly booster vaccinations were offered as follow-up treatment. Immune responses were measured as delayed-type hypersensitivity skin reaction and in vitro T-cell proliferation. GV1001 was well tolerated. Immune responses were observed in 24 of 38 evaluable patients, with the highest ratio (75%) in the intermediate dose group. Twenty-seven evaluable patients completed the study. Median survival for the intermediate dose-group was 8.6 months, significantly longer for the low- (P=0.006) and high-dose groups (P=0.05). One-year survival for the evaluable patients in the intermediate dose group was 25%. The results demonstrate that GV1001 is immunogenic and safe to use. The survival data indicate that induction of an immune response is correlated with prolonged survival, and the vaccine may offer a new treatment option for pancreatic cancer patients, encouraging further clinical studies.

Abstract
BACKGROUND Nonoperative management (NOM) of patients with severe splenic injuries carries a significant risk of failure. We hypothesized that adding angiographic embolization (AE) to the NOM protocol would decrease the laparotomy rate, and increase the success rate of NOM and splenic salvage rate. METHODS A protocol introducing AE in the treatment of splenic injuries was implemented. AE was performed in OIS splenic injury grades 3 to 5 and in all cases where signs of ongoing bleeding were encountered regardless of injury grade. Patients included in a prospective study during a 24-month period were compared with a historic control group. RESULTS Group 1 (before AE) consisted of 69 patients with a mean Injury Severity Score (ISS) of 31, and group 2 (after introducing AE) included 64 patients with a mean ISS of 30. In group 1, 30 patients underwent immediate laparotomy (43%), and the NOM success rate was 79%. After introducing AE, 17 patients underwent immediate laparotomy (27%; p = 0.04), with a NOM success rate of 96% (p = 0.02). Overall splenic salvage rate increased from 57% to 75% (p = 0.02). Angiography was performed in 31 patients in group 2. Embolization was performed in 27 of these patients. AE failure rate was 4%. NOM was successful in 14 of 15 patients with OIS injury grades 4 and 5 after the introduction of AE (93%). CONCLUSION A formal protocol adding mandatory AE to NOM for severe splenic injuries increased the percentage of patients in whom NOM was attempted, the NOM success rate, and the splenic salvage rate.

Abstract
OBJECTIVES To describe prospectively the prevalence and severity of disease-related symptoms, quality of life (QOL) and need for palliative care in patients with advanced pancreatic cancer. PATIENTS AND METHODS Fifty-one patients treated for advanced pancreatic cancer filled in the Edmonton Symptom Assessment Scale (ESAS) for symptom registration and the EORTC QLQ-C30 and QLQ-PAN26 quality of life questionnaires at first contact (baseline) and the ESAS in the following consultations. Need for palliative interventions were registered. RESULTS Of the 22 women and 29 men (mean age, 62 years), 20 had locally unresectable cancer, 19 had metastatic disease, and 12 had recurrent disease after curative resection. Forty-six patients died during follow-up (median survival, 99 days). At baseline, patients reported significantly impaired QOL on nine of 15 scales/items (p<0.01) relative to the general population. Fatigue, loss of appetite, and impaired sense of well-being were the most troublesome symptoms on the ESAS, measured to 4.4(+/-2.8)/5.3(+/-2.3), 4.4(+/-3.2)/5.9(+/-2.7), and 4.0(+/-2.9)/4.6(+/-2.7) (mean+/-SD) at baseline and 8 weeks before death, respectively. Forty-four of the 51 (86%) initial consultations and 107 (58%) of the 185 follow-ups (124 clinical and 61 phone-calls) resulted in palliative care interventions, most frequently changes in opioid or laxative medication and dietary advice. CONCLUSIONS Patients with advanced pancreatic cancer develop several distressing symptoms. ESAS was useful for assessment of symptom prevalence and intensity and is a clinically adequate method for symptom control. A multidisciplinary approach is necessary for the best palliation of symptoms at the time of diagnosis and during follow-up.

Abstract
OBJECTIVE Some of the problems faced in trauma surgery are increasing non-operative management of abdominal injuries, decreasing work hours and increasing sub-specialisation. We wanted to document the experience of trauma team leaders at the largest trauma centre in Norway, hypothesising that the patient volume would be inadequate to secure optimal trauma care. METHODS Patients registered in the hospital based Trauma Registry during the 2-year period from 1 August 2000 to 31 July 2002 were included. RESULTS Of a total of 1667 patients registered, 645 patients (39%) had an Injury Severity Score (ISS)>15. Abdominal injuries were diagnosed in 205 patients with a median ISS of 30. An average trauma team leader assessed a total of 119 trauma cases a year (46 patients with ISS>15) and participated in 10 trauma laparotomies. CONCLUSION Although the total number of trauma cases seems adequate, the experience of the trauma team leaders with challenging abdominal injuries is limited. With increasing sub-specialisation and general surgery vanishing, fewer surgical specialties provide operative competence in dealing with complicated torso trauma. A system of additional education and quality assurance measures is a prerequisite of high quality, and has consequently been introduced in our institution.

Abstract
OBJECTIVE To evaluate the benefit of a compulsory operative trauma care course for general surgeons in Norway utilising a live porcine model. METHODS The participants rated their expertise in 23 situations pre- and post-session on a scale 1-5, where 1 meant "not competent" and 5 meant "fully competent". RESULTS Mean total score increased 43% from pre- to post-session. The increase reached significance with all levels of experience. Procedures rarely performed, like suturing on a beating heart, showed a greater educational benefit than more frequently performed procedures, like inserting a chest tube. CONCLUSION The operative trauma care animal session increased the participants' perceived competence significantly. Its use seems justified for education in trauma related lifesaving surgical procedures.

Abstract
UNLABELLED Abdominal compartment syndrome(ACS) is a clinical entity characterised by increased intraabdominal pressure leading to multiple organ failure, fatal if left untreated. The treatment of abdominal compartment syndrome is surgical decompression with a temporary abdominal wall substitute. To avoid the development of abdominal compartment syndrome, temporary abdominal closure (TAC) should be considered after celiotomy for trauma. A new method for TAC was introduced at Ullevaal University Hospital in 2002, the "vac pac". METHOD The "vac pac" technique is described and the patients treated with "vac pac" during the first year after introduction are presented. RESULTS Five patients were treated using the "vac pac". One patient had acute pancreatitis and developed abdominal compartment syndrome. The other patients were severely injured and the indication for TAC was abdominal compartment syndrome in one patient, intestinal oedema in another, and damage control surgery with packing in two patients. Delayed primary closure was achieved within five days in all our patients. There were no fatalities and no complications related to the use of "vac pac" were registered. CONCLUSION The "vac pac" technique seems to be a good method for TAC.

Abstract
BACKGROUND We assessed the feasibility of outpatient laparoscopic splenectomy, as performed by an experienced laparoscopic term and combined with optimal anesthesia. METHODS Inclusion criteria in the study was limited to patients not hospitalized before the procedure who had hematological or neoplastic indications for splenectomy and were classified as American Society of Anesthesiologists (ASA) I-III. They received general intravenous anesthesia with propofol and remifentanil and were given keterolac, propacetamol, droperidol, and ondansetron as prophylaxis against postoperative pain and nausea. Laparoscopic splenectomy was performed via three trocars. The specimen was removed via an incision in the left iliac fossa. RESULTS Ten of the 12 patients were discharged 3-6 h postoperatively; the other two were admitted primarily to hospital. One was readmitted due to a fever, which was finally explained by measles. The median operative times was 58 min (range, 45-135). Patient satisfaction was excellent in nine and intermediate in two cases; it was poor in one case, due to postoperative pain. CONCLUSION Laparoscopic splenectomy can be completed in a relatively short time; therefore, it is feasible, safe, and satisfactory for most patients as an outpatient procedure.

Abstract
BACKGROUND The purpose of this paper is to describe the outcome of ambulatory laparoscopic cholecystectomy (LC), antireflux surgery, adrenalectomy and splenectomy and possible implications for surgical education and health care costs. METHODS Prospective, observational study 1994-2003. RESULTS The success rate of ambulatory treatment was 83.5% in 1060 LC patients, 80% in 113 antireflux procedures, 100% in 22 laparoscopic adrenalectomies, and 75% in 12 laparoscopic splenectomies. In a total number of 1207 patients, health care costs were reduced by almost 700,000 dollars, compared to 1-day hospital stay. The educational potential of same-day surgery is large, due to high numbers of patients, and 80% of our educational potential has been exploited. CONCLUSION Ambulatory laparoscopic surgery is cost effective, patient friendly, and appropriate for surgical resident training. Strict organization of security rules is mandatory.
