Nonetheless, insertion of some devices is invasive enough to be associated with bleeding, especially in patients with previous coagulopathy or in treatment with antithrombotic drugs for cardiovascular disease. The current practices of platelet/plasma transfusion in coagulopathic patients and of temporary suspension of the antithrombotic treatment before VAD insertion are based on local policies and are often inadequately supported by evidence, since many of the clinical studies on this topic are not recent and are not of high quality. Furthermore, the protocols of antithrombotic treatment have changed during the last decade, after the introduction of new oral anticoagulant drugs. Though some guidelines address some of these issues in relation with specific procedures (port insertion, etc.), no evidence-based document covering all the aspects of this clinical problem is currently available. Thus, the Italian Group of Venous Access Devices (GAVeCeLT) has decided to develop a consensus on the management of antithrombotic treatment and bleeding disorders in patients requiring VADs. After a systematic review of the available evidence, the panel of the consensus (which included vascular access specialists, surgeons, intensivists, anesthetists, cardiologists, vascular medicine experts, nephrologists, infective disease specialists, and thrombotic disease specialists) has structured the final recommendations as detailed answers to three sets of questions: (1) which is an appropriate classification of VAD-related procedures based on the specific bleeding risk? (2) Which is the appropriate management of the patient with bleeding disorders candidate to VAD insertion/removal? (3) Which is the appropriate management of the patient on antithrombotic treatment candidate to VAD insertion/removal? Only statements reaching a complete agreement were included in the final recommendations, and all recommendations were offered in a clear and synthetic list, so to be easily translated into clinical practice.

We aimed investigate whether the time trends of blood glucose levels in the perioperative period could be a determinant of surgery-related infections. Methods: Adult patients without diabetes who were candidates for elective major abdominal operation were prospectively enrolled in a longitudinal, observational multicenter study. The blood glucose level was measured every 6 h for 3 days. We calculated the association between blood glucose (BG) levels and the risk of occurrence of surgery-related infections using a joint regression modeling for longitudinal and time-to-event outcomes which accounts for the effect of other risk factors. Results: Between January 2016 and November 2017, we obtained 6078 BG measures distributed on different time-points in 452 patients. There was a nearly 3-fold increased risk of having hyperglycemia, defined as BG 125 mg/dL, if the BG level at admission was >100 mg/dL (OR ¼ 2.986, P < 0.001).The hazard of infection for each 10 mg/dL increase of BG levels over time was marginal (HR ¼ 1.065, P ¼ 0.045). The calculated risk of having an infection was 9.6% for BG going from 110 mg/dL during surgery to 84 mg/dL at the end of day 3, 10.5% for BG decreasing from 140 to 114, 11.8% for BG decreasing from 180 to 154 and 24.5% for BG increasing from 80 to 145, 24.7% for BG increasing from 110 to 175, and 25.4% for BG increasing from 140 to 205. Conclusions: The time trends of BG e as opposed to the absolute concentration eare major determinants of the risk of postoperative infections.

Resectability of the primary tumour has never been considered in outcome comparisons between operated and non-operated patients. Methods: From two institutional prospective databases of patients affected by PNET and unresectable liver metastases, 63 patients who underwent a left-pancreatectomy at diagnosis were identified and compared with a group of 30 patients with a potentially resectable but not-resected primary tumour located in the body or tail. The endpoint was overall survival (OS). Results: The two groups significantly differed at baseline with regard to liver tumour burden Ki-67 labelling index, site of pancreas, results of the 18 FDG PET-CT and age. In the operated patients, surgical morbidity comprised 7 cases of pancreatic fistula. Postoperative mortality was nil. Median OS for patients undergoing left-pancreatectomy was 111 months vs 52 for the non operated patients (p ¼ 0.003). At multivariate analysis after propensity score adjustment, no surgery as well as liver tumour burden>25% and higher Ki-67 index were associated with an increased risk of death during follow-up. In patients with unresectable primary tumour, OS was similar in comparison to that in the resectable but non-resected patients, and significantly worse than that in the resected patients (p ¼ 0.032). Conclusion: In PNETs located in the body or tail and diffuse liver metastases distal pancreatectomy may be justified in selected patients. Randomized studies may be safely proposed in future on this topic.

A G2P1 37-year-old woman presented during the 19th week of gestation because of pruritus at lower limbs. To exclude cholestasis, an abdominal ultrasound and whole body magnetic resonance were performed and a single solid lesion with intrinsic vascularization was identified. Therefore, at 22 weeks gestation, after normal fetal assessment, the patient was referred for a splenectomy. No further treatment was suggested and the patient gave birth at 42 weeks gestation with a spontaneous delivery. Distinguishing SANT from other vascular neoplasms of the spleen during pregnancy is a difficult task. Surgical excision should be performed to exclude malignancy and to resolve symptoms, if present.

From February 2004 to August 2007, 82 consecutive eligible patients were enrolled. According to the Hasenclever index, 64 patients (78%) were considered at low risk, 15 (18%) at intermediate and 3 (4%) at high risk. The most relevant toxicity was haematological: grade 3-4 neutropenia occurred in 32% of patients, grade 3-4 anaemia in 26% of patients. Severe infections and febrile neutropenia were observed in 8% of patients. With a median follow-up of 35 months (range 12-55), the three-year freedom from treatment failure (FFTF) and overall survival (OS) were 75% (95% CI 65%-86%) and 94% (95% CI 87%-99%), respectively. The intensified ChlVPP/ABVVP regimen in advanced HL is effective, does not seem to differ from standard regimens in terms of FFTF and OS and showed a favourable toxicity profile.

They underwent placement of a central venous port via the subclavian vein for delivery of chemotherapy and reinfusion of stem cells. All patients were followed prospectively for device-related and overall complications, comprising a total of 18 213 days in situ (median: 267 days, range: 90-480). One patient experienced a pneumothorax (1.4%) spontaneously resolved, as an acute toxicity. Two patients (2.8%, 0.1 episodes/1000 days of use) were forced to have the port removed due to infection, caused by Streptococcus mitis in one case, while the causative agent was not identified by laboratory tests in the second. The other 66 patients completed the therapeutic programme, including peripheral stem cell reinfusions and supportive care, such as i.v. antibiotics, antiemetics or fluid administration and blood sample collection, without additional complications. In conclusion, the use of totally implantable central venous access ports has resulted in good long-term access to central veins, in spite of the severe neutropenia and increased septic risk of this category of oncology patients. Keywords: central venous catheters; ports; high-dose chemotherapy; autologous stem cell transplantation Central venous access is always necessary for the management of patients undergoing high-dose chemotherapy (HDCT) with concomitant BMT (bone marrow transplantation) or autologous PBSCT (peripheral blood stem cells transplantation). The systematic use of these devices reduces the need to enter the venous system to draw blood samples and administer cytotoxic drugs, antibiotics, blood products, fluids, and nutrition, which are essential parts of therapy. Moreover, high-flow venous catheters may also be used for the collection of peripheral stem cells.

This prospective study deals with the complications and global costs of central venous ports connected to a Groshong catheter for deliverance of long-term chemotherapy. Patients and methods: Patients with a variety of solid neoplastic diseases requiring chemotherapy who were undergoing placement of implantable ports over a 30-month period (1 October 1994 to 31 March 1997) have been prospectively studied. Follow-up continued until the device was removed or the study was closed (30 September 1997); patients with uneventful implant experience and subsequent follow-ups of less than 180 days were not considered for this study. A single port, constructed of titanium and silicone rubber (Dome Port®, Bard Inc., Salt Lake City, USA), was used, connected to an 8 F silastic Groshong® catheter tubing (Bard Inc., Salt Lake City, USA). Two-hundred ninety-six devices were placed in the operating room under fluoroscopic control even in the patients treated and monitored in a day-hospital setting; 37 of them were in an angiographic suite. A central venous access form was filled in by the operator after the procedure and all ports were followed prospectively for devicerelated and overall complications. The average purchase cost of the device was obtained from the hospital charges, based on the costs applied during the 30month period of the study. Insertion and maintenance costs were estimated by obtaining the charges for an average T1AP implant and its subsequent use; the costs of complication management were assessed analytically. The total cost of each device was defined as the purchase cost plus the insertion cost plus the maintenance cost plus the cost of treatment of the complications, if any. The cost of removing the TIAP was also included in the economic analysis when required by the treatment of the complication. Results: Three hundred thirty-three devices, for a total of 79,178 days in situ, were placed in 328 patients. Five patients received second devices after removal of the first. In all cases the follow-up was appropriate (median 237 days, range 180-732). Early complications included 10 pneumothoraxes (3.4%; six tube-thoracostomies were applied, 1.8%) and six revisions for port and/or catheter malfunction (overall early complications = 16, 4.48%). Late complications comprised five instances of catheter rupture and embolization (1.5%, 0.063 episodes/1000 days of use), five of venous thrombosis (1.5%, 0.063 episodes/ 1000 days of use), one of pocket infection (0.3%, 0.012 episodes/ 1000 days of use), and eight of port-related bacteremia (2.4%, 0.101 episodes/1000 days of use). The infections were caused by coagulase-negative Staphylococcus aureus (five cases), Bacillus subtilis (one case), Streptococcus lactaceae (one case) and an unknown agent (one case); port removal was necessary in six of eight cases. The total cost per patient treated for a six-month period, consisting of the costs of purchase and implantation, treatment of early and late complications, and of maintenance of the device, is US$1,970. Conclusions: This study represents the largest published series of patients with totally implantable access ports connected to a Groshong catheter. We have shown that US$2,000 are sufficient to cover six months of chemotherapy in one patient using the most expensive commercially available implantable port. According to the present study, totally implantable access ports connected to a Groshong catheter are associated with high purchase and insertion costs, a low complication rate and low maintenance costs. These data support their increasing use in current oncologic medical practice.
