Our aim was to characterize the periosteal microvascular reaction induced by the destruction of endosteal vasculature by reaming, and to monitor the time sequence of the events. We have also compared the microcirculatory effects of different implant materials that are most frequently employed in human endoprosthetics. ⋯ Enhanced periosteal angiogenesis could be demonstrated after 12 weeks following tibial reaming. The compensatory microvascular reactions evoked by destruction of endosteal microcirculation of long bones are not influenced by osseo-integrative implant materials, but materials of poor osseointegration properties induce considerable compensatory increases in the microvascular density of the periosteum.

Randomized Controlled Trial Multicenter Study Comparative Study
[Comparison of wound infection rates after colon and rectal surgeries using triclosan-coated or bare sutures -- a multi-center, randomized clinical study].
Surgical Site Infection (SSI) is the third most frequent nosocomial infection, and accounts for 14-16% of all infections. While the treatment of SSI can be very costly, previous results indicated that triclosan may reduce SSI rate. Therefore, we carried out a prospective randomised trial to further evaluate the effect of triclosan after elective colorectal surgery. ⋯ Beneficial effect of triclosan against Gram positive bacteria could not be confirmed in our study due to the relatively low number of patients with SSI. Furthermore, triclosan did not influence the incidence of SSI due to Gram negative bacteria. SSI rate decreased by 50% compared to our previous study, however, it was regardless of the use of coated or uncoated PDS loop. Finally, operative factors were more important than patient's risk factors in terms of incidence of SSI. In case SSI developed, delayed discharge from hospital as well as special wound care significantly increased overall cost of treatment.

The incidence of intraabdominal hypertension or abdominal compartment syndrome, as the more severe form is called, is relatively high in patients with severe acute pancreatitis, and therefore more attention is needed to the topic. If conservative treatment fails, immediate surgical decompression is indicated. ⋯ The open abdomen therapy is not advised due to high morbidity. Primary closure of the abdomen is preferable.

Authors present two cases of successfully operated patients with retrohepatic inferior vena cava (IVC) injury. In the first case a 79 year old female patient suffered from multiple stab wounds in the area of the 4th segment of the right lung as well as in the retrohepatic region in close proximity to the IVC. At the time of the first surgery the IVC injury was not identified. During a second operation, however, the IVC was isolated from the liver using an anterior dissection of the parenchyma with finger-fracture technique and the injury was oversawn finally. Successful haemostasis of the liver was achieved by packing of the perihepatic space, which was removed three days later. In the second case a 25 year-old male patient had suffered blunt abdominal trauma. He underwent laparotomy and packing on the site of the hepatic injury, which had to be repeated seven more times. Later on, another urgent laparotomy was carried out for recurring intraabdominal bleeding and bile leakage, and cholecystectomy was performed due to gallbladder perforation. Another two days later a further emergency laparotomy was indicated for ongoing intraabdominal bleeding, when the bleeding source - an injury (3 mm in diameter) of the retrohepatic IVC - was oversawn. After relatively long postoperative stay both patients were fully recovered and discharged from hospital. ⋯ penetrating injuries of the IVC are associated with high mortality rate of approximately 78%. Proper management of these injuries requires experience in both vascular and liver surgery. Retrohepatic IVC injury needs to be considered in the differential diagnosis of ongoing bleeding in penetrating or blunt liver trauma. Packing of the liver is a reliable haemostatic method if bleeding persists due to division of the liver parenchyma.

Surgical infections are severe complications of surgical interventions and one of the most important patient safety issues. These are associated with increased morbidity, mortality, costs and decreased quality of life. Prevention of infections is essential, while one has to consider pre-, intra- and postoperative factors and procedures in the clinical practice. In this article we summarize the latest recommendations for clinicians based on the relevant published literature.
