Safety and effectiveness of a synthetic hemostatic patch for intraoperative soft tissue bleeding.

ABSTRACT: BACKGROUND:Continuous bleeding after using conventional hemostatic methods involving energy, sutures, or clips, is a serious and costly surgical complication. Many topical agents have been developed to promote intraoperative hemostasis, but improvement is needed in both decreasing time to hemostasis and increasing ease of use. Veriset™ hemostatic patch is CE-marked for controlling bleeding on the liver and in soft tissue. In the current study, we aimed to gather further evidence for the safety and effectiveness of Veriset™ hemostatic patch in soft tissue bleeding during a variety of surgical procedures. METHODS:Thirty patients scheduled for nonemergency surgery, each with an intraoperative soft tissue bleeding site, were treated with Veriset™ hemostatic patch. Time to hemostasis was monitored, and adverse events were assessed during the 90 days after surgery. RESULTS:When Veriset™ hemostatic patch was used, hemostasis occurred within 5 minutes in 29/30 (96.7%) subjects and within 1 minute in 21/30 (70.0%) subjects. No device-related serious adverse events were recorded during the 30 days after surgery, and no reoperations for device-related bleeding complications were performed during the 5 days after surgery. CONCLUSIONS:Veriset™ hemostatic patch is a safe and effective hemostat for controlling soft tissue bleeding during a variety of surgical procedures.

Project description:Soft-tissue sarcoma (STS) represent a rare tumor entity, accounting for less than 1% of adult malignancies. The cornerstone of curative intent treatment is surgery with free margins, although the extent of the surgical approach has been subject to change in the last decades. Multimodal approaches usually including radiation therapy have replaced extensive surgical procedures in order to preserve functionality while maintaining adequate local control. However, the possibility to apply adequate radiation doses by external beam radiation therapy (EBRT) can be limited in some situation especially in case of directly adjacent organs at risk with low radiation tolerance. Application of at least a part of the total dose via intraoperative radiation therapy (IORT) with a single fraction during the surgical procedure may overcome those limitations, because radiosensitive structures can be moved out of the radiation field resulting in reduced toxicity while the enhanced biological effectivity of the high single dose improves local control. The current review summarizes rationale, techniques, oncological and functional outcomes including possible pitfalls and associated toxicities based on the published literature for IORT focusing on extremity and retroperitoneal STS. In extremity STS, combination of limb-sparing surgery, IORT and pre- or postoperative EBRT with moderate doses consistently achieved excellent local control rates at least comparable to approaches using EBRT alone but usually including patient cohorts with higher proportions of unfavourable prognostic factors. Further on, IORT containing approaches resulted in very high limb preservation rates and good functional outcome, probably related to the smaller high dose volume. In retroperitoneal STS, the combination of preoperative EBRT, surgery and IORT consistently achieved high local control rates which seem superior to surgery alone or surgery with EBRT at least with regard to local control and in some reports even to overall survival. Further on, preoperative EBRT in combination with IORT seems to be superior to the opposite combination with regard to local control and toxicity. No major differences in wound healing disturbances or postoperative complication rates can be observed with IORT compared to non-IORT containing approaches. Neuropathy of major nerves remains a dose limiting toxicity requiring dose restrictions or exclusion from target volume. Gastrointestinal structures and ureters should be excluded from the IORT area whenever possible and the IORT volume should be restricted to the available minimum. Nevertheless, IORT represents an ideal boosting method if combined with EBRT and properly executed by experiences users which should be further evaluated preferably in prospective randomized trials.
