Background: Significant intraoperative and postoperative blood loss are rare but possibly life-threatening complications after lung resection surgery either during open or minimally invasive procedures. Microporous Polysaccharide Haemospheres (ARISTA™AH) have demonstrated time-efficient haemostasis, lower postoperative blood volumes and a lower blood transfusion requirement, without any identified adverse events across other specialities. The primary aim of our study was to evaluate the impact of ARISTA™AH on short-term postoperative outcomes in thoracic surgery. Our secondary aim was to compare ARISTA™AH with other commonly used haemostatic agents. Methods: We retrospectively reviewed a prospectively collected database of consecutive early-stage lung cancer patients surgically treated in two European centres (October 2020–December 2022). Exclusion criteria included open surgery, patients with coagulopathy/anticoagulant medication, major intraoperative bleeding, non-anatomical lung resection and age <18 years. The cohort was divided into five groups according to the haemostatic agent that was used. Propensity score matching was used to estimate the effect of ARISTA™AH on various intra- and postoperative parameters (continuous and binary outcome modelling). Results: A total of 482 patients (M/F:223/259; VATS 97/RATS 385) with a mean age of 68.9 (±10.6) years were analysed. In 253 cases, ARISTA™AH was intraoperatively used to control bleeding. This cohort of patients had a significant reduction in total drain volume by 135 mls (standard error 53.9; p = 0.012). The use of ARISTA™AH did reduce the average length of a hospital stay (−1.47 days) and the duration of chest drainage (−0.596 days), albeit not significantly. In the ARISTA™AH group, we observed no postoperative bleeding, no blood transfusion requirement, no 30-day mortality and no requirement for redo surgery. The use of ARISTA™AH significantly reduced the odds of postoperative complications, as well as the need for transfusion and redo surgery. Conclusions: Our data showed that Microporous Polysaccharide Haemospheres are a safe and effective haemostatic device. Their use has a positive effect on the short-term postoperative outcomes of patients surgically treated for early-stage lung cancer. Full article

Rapid haemostasis during surgery is essential when one wants to reduce the duration of operations, reduce the need for transfusions, and above all when one wants to achieve better patient management. The use of haemostatic agents, sealants, and adhesives improves the haemostatic process by offering several advantages, especially in vascular surgery. These agents vary widely in their mechanism of action, composition, ease of application, adhesion to wet or dry tissue, immunogenicity, and cost. The most used are cyanoacrylate-based glues (Glubran 2) or polysaccharide hydrogel-microsphere powder (Arista^TMAH). This work is based on a retrospective study carried out on a sample of patients with different vascular diseases (FAV, pseudoaneurysm, and PICC application) in which two different haemostatic sealants were used. The aim was to assess the safety, the advantages, and the ability of both sealants to activate the haemostatic process at the affected site, also in relation to their chemical-physical characteristics. The obtained results showed that the application of Glubran 2 and Arista^TMAH as surgical wound closure systems is effective and safe, as the success achieved was ≥94% on anastomoses of FAV, 100% on stabilization of PICC catheters, and ≤95% on pseudoaneurysms.

Background: Bleeding is one of the most fearsome and life-threatening complications after thyroid surgery. Several medical devices and haemostatic agents have been proposed to improve haemostasis during total and hemi-thyroidectomy. Resorbable polysaccharide powder (HaemoCer™) is a plant-based polymer that is helpful in terms of the coagulation cascade becoming a gel and forming a barrier to prevent further bleeding, having tested for haemostasis in different districts. The aim of the current study was the evaluation of drain output, the presence of significant postoperative blood loss and complications in patients treated with or without resorbable polysaccharide powder during thyroid surgery. Methods: From January to December 2022, postoperative bleeding, drainage output and the postoperative wound events of patients undergoing thyroid surgery, in a tertiary centre, with haemostasis completion with resorbable polysaccharide powder (Group A) or not (Group B), were retrospectively analysed. Results: Eighty-one patients in Group A received a haemostasis improvement with the use of reabsorbable polysaccharide powder, and 96 patients in Group B received thyroid surgery alone. Patients in Group A presented lower drainage output (0.005), lower incidence of neck haematoma (0.005) and seroma (0.021), confirmed also by multivariate analysis. Conclusions: The resorbable polysaccharide powder, in the current series, appeared to be an effective agent in achieving haemostasis in thyroidectomies, reducing the postoperative drainage output, and also neck events such as neck haematoma and seroma, improving the postoperative comfort of the patients. Further larger comparative studies are needed to address this issue. Full article
