BackgroundThe clinical importance of intraductal papillary mucinous neoplasm (IPMN) have increased last decades. Long-term survival after resection for invasive IPMN (inv-IPMN) compared to conventional pancreatic ductal adenocarcinoma (PDAC) is not thoroughly delineated.ObjectiveThis study, based on the Swedish national pancreatic and periampullary cancer registry aims to elucidate the outcome after resection of inv-IPMN compared to PDAC.MethodsAll patients ≥18 years of age resected for inv-IPMN and PDAC in Sweden between 2010 and 2019 were included. Clinicopathological variables were retrieved from the national registry. The effect on death was assessed in two multivariable Cox regression models, one for patients resected 2010–2015, one for patients resected 2016–2019. Median overall survival (OS) was estimated using the Kaplan-Meier method.ResultsWe included 1909 patients, 293 inv-IPMN and 1616 PDAC. The most important independent predictors of death in multivariable Cox regressions were CA19-9 levels, venous resection, tumour differentiation, as well as T-, N-, M-stage and surgical margin. Tumour type was an independent predictor for death in the 2016–2019 cohort, but not in the 2010–2015 cohort. In Kaplan-Meier survival analysis, inv-IPMN was associated with longer median OS in stage N0-1 and in stage M0 compared to PDAC. However, in stage T2-4 and stage N2 median OS was similar, and in stage M1 even shorter for inv-IPMN compared to PDAC.ConclusionIn this population-based nationwide study, outcome after resected inv-IPMN compared to PDAC is more favourable in lower stages, and similar to worse in higher. 相似文献

BackgroundResections for intraductal papillary mucinous neoplasia (IPMN) have increased dramatically during the last decade. Recurrence pattern and impact of adjuvant chemotherapy for solid pancreatic ductal adenocarcinoma (PDAC) is well known, but not for invasive IPMN (inv-IPMN).ObjectivesTo elucidate the impact of spatio-temporal recurrence pattern and adjuvant chemotherapy on overall survival for inv-IPMN compared with PDAC.MethodsWe conducted a retrospective single-center observational study of consecutive patients ≥18 years of age who underwent resection for inv-IPMN or PDAC at Karolinska University Hospital, between 2009 and 2018. Different initial recurrence sites and time frames as well as predictors for death were assessed with multivariable Cox and logistic regressions. Survival analyses were performed using the Kaplan-Meier model and log rank test.ResultsOf 396 resected patients, 92 were inv-IPMN and 304 PDAC. Both recurrence rate and death rate within three-years were lower for inv-IPMN compared to PDAC (p = 0.006 and p = 0.007 respectively). Across the whole cohort, the most common recurrence patterns were multi-site (25%), single-site liver (21%) and single-site locoregional (10%) recurrence. The most prominent predictors for death in multivariable Cox regression, especially if occurred within the first year, were multi-site (HR 17.0), single-site peritoneal (HR 13.6) and single-site liver (HR 13.1) recurrence. These predictors were less common in inv-IPMN compared to PDAC (p = 0.007). The effect of adjuvant chemotherapy was similar in the two groups.ConclusionResected inv-IPMN exhibits a less aggressive recurrence pattern than PDAC that translates into a more favorable overall survival. 相似文献

AbstractIntroduction: Endoscopic submucosal dissection (ESD) is extensively performed for the treatment of early gastric cancer (EGC) in the Eastern countries due to its favourable outcomes compared to gastrectomy in terms of lower complication rates, shorter hospital stays, better quality of life, with similar 5-year survival rate. Yet, its use is still limited in the UK.Aim: A long-term follow-up study to evaluate the outcome of ESD in the treatment of EGC in a Caucasian population at a tertiary referral centre in the United Kingdom.Methods: Data for the 35 Caucasian patients, who underwent ESD in a tertiary referral centre between May 2012 and June 2017 were collected. The selected patients were followed-up until May 2018. Curative resection (CR) and survival rates were used to measure the efficacy of ESD.Results: ESD was attempted on 46 lesions and completed on 37. En-bloc and CR rates of 57% and 19% were achieved, respectively. 24% of the lesions were non-CR and 57% were indefinite for non-CR/CR and 41% of the lesions showed change in histological grade post-ESD. Complete reversal of dysplasia/neoplasia was seen in 60% of the ‘indefinite’ group and 100% of the CR group at latest FU (18 months, mean). Recurrence was seen in 23% of the patients at latest FU. Seventy-one months’ survival rate was 77%, while the disease-specific mortality was 0%.Conclusions: This study demonstrates the positive long-term outcome of ESD for gastric neoplasia in a UK Caucasian population, encouraging further development and implementation of ESD in the UK. 相似文献

BACKGROUND AND AIMS: Recent consensus guidelines suggest that presence of > or =1 of the following is an indication for resection (IR) of branch duct intraductal papillary mucinous neoplasm (IPMN-Br): cyst-related symptoms, main pancreatic duct diameter > or =10 mm, cyst size > or =30 mm, intramural nodules, or cyst fluid cytology suspicious/positive for malignancy. Among a cohort of patients with IPMN-Br we determined if the consensus IR (CIR), presence of multifocal IPMN-Br, or growth of cyst size on follow-up predict malignancy. METHODS: We identified 147 patients with IPMN-Br of whom 66 underwent surgical resection at diagnosis and 81 were followed conservatively, of whom 11 were resected during follow-up. Clinical, imaging, histological, and cyst fluid characteristics from all 147 patients with IPMN-Br were obtained from clinical records and/or by contacting the patients. In all cases, presence of CIR at baseline and during follow-up (N = 66), presence of multifocal cysts (N = 57), and increase in cyst size (N = 38) were noted. RESULTS: Among the 77 resected IPMN-Brs, at initial evaluation 61 had at least one CIR and 16 had none. Malignancy was present in 9/61 (15%) with CIR and 0/16 without IR (P= 0.1). When presence of any one of the CIR was taken as an indicator of malignancy, the CIR had a sensitivity, specificity, positive predictive value, and negative predictive value of 100%, 23%, 14%, and 100%, respectively. Prevalence of malignancy in those with single versus multifocal IPMN-Br was similar (13%vs 11%). No patient has developed malignancy after a median follow-up of 15 months. So far, none of the 38 patients with increase in cyst size on follow-up has developed malignancy related symptoms. CONCLUSIONS: Suggested consensus indications for resection identify all patients with malignancy; however, their specificity is low. In the short term it would be safe to follow patients without these features. 相似文献

Background/objectivesThe detection of malignancy is a major concern in the management of intraductal papillary mucinous neoplasm (IPMN). The height of the mural nodule (MN), estimated using endoscopic ultrasound (EUS) and computed tomography (CT), has been considered crucial for predicting malignant IPMN. Currently, whether surveillance using CT or EUS alone is sufficient for detecting MNs remains unclear. This study aimed to compare the ability of CT and EUS to detect MNs in IPMN.MethodsThis multicenter, retrospective observational study was conducted in 11 Japanese tertiary institutions. Patients who underwent surgical resection of IPMN with MN after CT and EUS examinations were eligible to participate. The MN detection rates between CT and EUS were examined.ResultsTwo-hundred-and-forty patients who underwent preoperative EUS and CT had pathologically confirmed MNs. The MN detection rates of EUS and CT were 83% and 53%, respectively (p < 0.001). Additionally, the MN detection rate of EUS was significantly higher than that of CT regardless of morphological type (76% vs. 47% in branch-duct-type IPMN; 90% vs. 54% in mixed IPMN; 98% vs. 56% in main-duct-type IPMN; p < 0.001). Further, pathologically confirmed MNs ≥5 mm were more frequently observed on EUS than on CT (95% vs. 76%, p < 0.001).ConclusionsEUS was superior to CT for the detection of MN in IPMN. EUS surveillance is essential for the detection of MNs. 相似文献

AbstractBackground: 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. 相似文献

Background/Purpose
Liver resection is a widely preferred treatment modality for hepatocellular carcinomas (HCCs). This study aimed to compare the survival impact of anatomical resection with that of limited resection, in patients with single HCCs no larger than 5 cm in diameter.Methods
A cohort study was carried out on 209 consecutive patients who underwent hepatic resection for a single HCC no larger than 5 cm in diameter between January 1994 and March 2007 at Osaka City General Hospital.Results
The cumulative 5-year overall survival and disease-free survival rates in the anatomical resection group (n = 111) were 71 and 40%, respectively, both of which were significantly better than the 48 and 25% seen in the limited resection group (n = 98) (P = 0.0043 and P = 0.0232, respectively). Better effects of the anatomical resection on both overall and disease-free survival were seen in patients having HCC larger than 2 cm in diameter and in patients with moderately or poorly differentiated HCC. But no significant difference in either overall or disease-free survival was seen between the groups in patients with a HCC 2 cm or less in diameter or in the patients with well-differentiated HCC. Using Cox’s regression model, anatomical resection was confirmed to be an independent favorable factor for both overall and disease-free survival.Conclusions
Anatomical resection is therefore recommended for histologically advanced single HCCs ranging from 2 to 5 cm in diameter. 相似文献10.

Introduction
Coronary artery ectasia (CAE) is a rare but well-recognised condition involving dilatation of a coronary artery to more than 1.5 times the diameter of the adjacent portion of the artery. As far as we are aware, the disease has not been described in any local literature and no other research has been conducted in Africa. We carried out this research in order to establish the incidence of the condition in South Africa, as well as the possible preferred method of treatment.Methods
Cases were identified from the database of the practice. The study involved only patients who were classified to have Markis type I, II and III disease. From a total of approximately 2 000 angiographies performed during the study period, CAE types I, II and III were diagnosed in 20 patients. Patients with type IV CAE were excluded from the group. Nineteen patients were male and were in their fourth or fifth decade of life, and one was female. Three of the patients were Indian, one was black, and the rest were white.Results
Four patients in the group had diabetes, 13 were smokers and eight had hypertension. Dyslipidaemia was observed in seven patients. The most commonly affected area of the coronary artery was the RCA-19 (isolated, or in combination). Patients were treated mainly with anticoagulation and, when necessary, with angioplasty and stent implantation. Morbidity was seen in 5% of the patients and no mortality was observed.Conclusion
Most of the patients were male, and the occlusion involved mostly the right coronary artery. The cause of occlusion is still unknown, but it is thought to be due to slow blood flow, damaged endothelium, or a combination of the two. The best therapeutic approach is not known as yet. 相似文献11.

The purpose of this study was to review the outcome of dialysis-dependent patients undergoing cardiac surgery. We retrospectively reviewed 81 dialysis-dependent patients with a mean age of 62.5 ± 9.4 years who underwent cardiac operations. Mean EuroScore was 7.1 ± 3.9 (>9 in 18 patients). Surgery included coronary artery bypass grafting (CABG) in 43 patients (53.1%), valve surgery in 16 (19.7%), combined CABG plus valve surgery in 19 (23.5%) and major aortic surgery in three patients. In-hospital mortality rate was 13.6%. Most of the deaths occurred in patients who underwent valve procedures or combined surgery. Preoperative New York Heart Association class IV, previous acute myocardial infarction, combined surgical procedures, major aortic surgery, age >70 years, history of heart failure, female gender, the duration of dialysis ≥ 5 years and urgent/emergent surgery were associated with high relative risk for perioperative death. The actuarial survival was 72.2% at 5 years. Predictors of increased late mortality were heart failure, urgent/emergent surgery, the complexity of the surgical procedures (valve surgery, combined CABG + valve and major aortic surgery) and postoperative low cardiac output syndrome. In dialysis-dependent patients, CABG has an acceptable risk. Results in patients affected by valve lesions associated or not with coronary artery disease are improved by an early referral to surgery, before the onset of symptoms of heart failure. 相似文献

Background Primary percutaneous intervention (PPCI) is the treatment of choice for ST elevation myocardial infarction (STEMI) but robust evidence in the very elderly is lacking. We compared PPCI outcomes between different age quartiles (quartile 1 < 60 years, quartile 2 ≥ 60 to < 70 years, quartile 3 ≥ 70 to < 80 years, quartile 4 ≥ 80 years). Methods Retrospective observational analysis of our Morriston Tertiary Cardiac Centre (Abertawe Bro Morgannwg University Health Board) patients from 2005 to 2010 with STEMI who underwent PPCI. Results Of 434 patients, 57 (13%) were in quartile 4 (≥ 80 years). In older age quartiles, patients were less likely to receive a drug eluting stent (DES, P = 0.001) or glycoprotein IIb/IIIa inhibitor (GPI, P < 0.0001). Increase in age was associated with reduced time to survival (β-coefficient: -0.192, t: -3.70, 95%CI: -4.91 to -1.50, P < 0.0001) as was the presence of cardiogenic shock (β-coefficient: -0.194, t = 3.77, 95%CI: -5.26 to -1.65, P < 0.0001). Use of GPI was associated with increased time to survival (β-coefficient: 0.138, t = 2.82, 95%CI: 1.58–8.58, P = 0.005) but older age quartiles were less likely to receive GPI (P < 0.0001). In-hospital mortality (1.8% quartile 1, 3.6% quartile 2, 10.9% quartile 3 and 12.3% quartile 4, P = 0.002) and 1-year mortality (5.4% quartile 1, 5.5% quartile 2, 16.8% quartile 3 and 24.6% quartile 4, P < 0.0001, respectively) was significantly higher in older age quartiles. Conclusions Increased short term and intermediate term mortality is seen in the very elderly after PPCI. Age and cardiogenic shock were prognostic factors. Intervention should not be based on age alone and awareness regarding prognostic factors can help improve management. 相似文献

Purpose
To determine risk factors for early postoperative complications and longer hospital stay after ileocecal resection and right hemicolectomy in a single-center cohort of patients with Crohn’s disease (CD).Methods
A retrospective analysis of the prospectively maintained surgical database for patients with CD at our institution was performed. All consecutive patients operated on between January 2010 and December 2016 were included.Results
A total of 305 patients were included. Median length of hospital stay was 7 days (interquartile range, IQR 6–10). Major postoperative complications were observed in 9.5% of patients (n?=?29). Anastomotic leak was observed in five patients (1.8% of all patients with anastomosis). The rate of local septic complications was 4.3% (n?=?13, anastomotic leak, postoperative abscess, and/or postoperative fistula). In multivariable analysis, independent risk factors for major postoperative complications were bowel perforation (odds ratio (OR)?=?12.796, 95% CI?=?1.144–143.178); elevated preoperative leucocyte levels (OR?=?1.115, 95% CI?=?1.013–1.228); and low levels of preoperative albumin (OR?=?0.885, 95% CI?=?0.827–0.948). The cutoff value for albumin was 32.5 g/L (sensitivity 75.9%, specificity 62.6%).Conclusions
In this large cohort of patients surgically treated for CD in a tertiary referral center, 9.5% of the patients developed major postoperative complications. Preoperative albumin levels >?32.5 g/L significantly reduce the risk for postoperative complications and shorten the length of hospital stay. In a multidisciplinary concept with adequate preoperative management, surgery can be performed with a low rate of major complications and a very low rate of anastomotic leakage.18.

Mechanisms causing liver fibrosis during chronic hepatitis C virus infection (cHCV) are not sufficiently understood. This study was aimed to identify biomarkers for early fibrosis (EF) and to investigate their potential role in cHCV-related fibrogenesis. To this end, peripheral whole blood (PB) samples from 36 patients with cHCV recruited from two independent cohorts were subjected to microarray analysis 12 h before initiation of peginterferon-alpha (Peg-IFN-α) and ribavirin therapy. Liver biopsies were evaluated using the Batts-Ludwig staging (BL-S) classification system for fibrosis. We showed that gene expression profiles (N = 8) distinguished between EF (BL-S: 0,1) and late fibrosis (LF; BL-S: 2,3,4) with 88.9% accuracy. Fibrosis-related functional annotations for chemokine-'C-C-motif' ligand 5 (CCL5) provided foundation for focused investigation, and qRT-PCR confirmed that CCL5 mRNA levels (PB) reliably discriminate EF from LF (accuracy: 86.7%). Positive correlations (P < 0.05) with CCL5 mRNA levels and EF discovered gene expression profiles (PB) reflecting stable expression of IFN-α receptor 1, negative regulation of the MyD88-dependent toll-like receptor (TLR) pathway and decreased expression of TLR3 in vivo. Remarkably, Peg-IFN-α suppressed CCL5 mRNA levels (PB) in EF in vivo. These findings along with results from parallel in vitro investigation into the effect of IFN-α or poly I:C (TLR3-agonist) on CCL5 gene expression in hepatic stellate cells (HSC) attest to the multi-site involvement of these pathways in regulating fibrogenesis. In conclusion, we identified novel, reliable biomarkers for EF and exposed functional properties of the molecular network regulating CCL5 biosynthesis in peripheral or hepatic cell types with key roles in cHCV-related liver and/or immune pathogenesis. 相似文献
