ABSTRACT

The aim of this article is to present the importance of a structured and situation-adapted approach based on the diagnostic and therapeutic strategy in the interdisciplinary treatment of 54 patients with deep sternal wound infections (DSWI) after cardiac surgical interventions and the results achieved. The patients were 41 men and 13 women with an average age of 65.1 years, who developed a DSWI after a cardiac surgical intervention during the period 2003-2016. The treatment strategy included a thorough debridement including the removal of indwelling foreign material, the reconstruction with a stable re-osteosynthesis after overcoming the infection and if necessary, situation-related surgical flaps for a defect coverage with a good blood supply and mandatory avoidance of dead spaces. A total of 146 operations were necessary (average 2.7 operations/patient, range 1-7 operations). In 24.1 % of the cases a one-stage approach could be carried out. In 41 patients negative pressure wound therapy (NPWT) with programmed sponge changing was used for wound conditioning (mean 5 changes, standard deviation, SD±â€¯5.6 changes over 22 days, SD±â€¯23.9 days, change interval every 3-4 days in 40.7% of the cases). In 33 patients a bilateral myocutaneous pectoralis major flap was used, in 4 patients a vertical rectus abdominis myocutaneous (VRAM) flap and in 7 patients both were carried out. A total of 43 osteosynthesis procedures were carried out on the sternum with fixed-angle titanium plates. Of the patients 7 died during intensive care unit treatment (total mortality 13 %, n = 5, 9.3 % ≤ 30 days) or in the later course. Of the patients 47 (87.1 %) could be discharged with a cleansed infection. In 2 patients the implant was removed after 2 years due to loosening.

ABSTRACT

The incidence of terrorist attacks is increasing worldwide, and they have also become a permanent threat in European cities. Due to its complexity, terrorist attack trauma places high demands on the strategy of surgical treatment. The combination of various mechanisms, explosions and gunshot injuries, with the characteristic pressure (blast) damage and a high proportion of penetrating trauma with simultaneous burns are characteristic features. Unlike in military conflicts, injuries to people of all ages and without ballistic body protection (body armor) are to be expected. The mechanism of the attack and its local conditions are of relevance for the assessment of the situation and the expected injury patterns. Thus, suicide attacks result in several times higher numbers of fatalities and casualties. Explosions on free ground lead to different types of injury than those in closed or semi-enclosed spaces. The treatment principles of the Advanced Trauma Life Support (ATLS®) are based on the intrahospital care of casualties as well as damage control strategies with trigger factors. In order to prepare and educate clinics and surgeons in Germany for such scenarios, various course formats of the professional societies, the German Society for General and Visceral Surgery (DGAV) and the German Society for Trauma Surgery (DGU) have now been established.

ABSTRACT

BACKGROUND: Blast injuries are a rare cause of potentially life-threatening injuries in Germany. During the past 30 years such injuries were seldom the cause of mass casualties, therefore, knowledge and skills in dealing with this type of injury are not very extensive. MATERIAL AND METHODS: A retrospective identification of all patients in the TraumaRegister DGU® of the German Trauma Society (TR-DGU) who sustained blast injuries between January 1993 and November 2012 was carried out. The study involved a descriptive characterization of the collective as well as three additional collectives. The arithmetic mean, standard deviation and 95 % confidence interval of the arithmetic mean for different demographic parameters and figures for prehospital and in-hospital settings were calculated. A computation of prognostic scores, such as the Revised Injury Severity Classification (RISC) and the updated version RISC II (TR-DGU-Project-ID 2012-035) was performed. RESULTS: A total of 137 patients with blast injuries could be identified in the dataset of the TR-DGU. Of the patients 90 % were male and 43 % were transported by the helicopter emergency service (HEMS) to the various trauma centres. The severely injured collective with a mean injury severity scale (ISS) of 18.0 (ISS ≥ 16 = 52 %) had stable vital signs. In none of the cases was it necessary to perform on-site emergency surgery but a very high proportion of patients (59 %) had to be surgically treated before admittance to the intensive care unit (ICU). Of the patients 27 % had severe soft tissue injuries with an Abbreviated Injury Scale (AIS) ≥ 3 and 90 % of these injuries were burns. The 24 h in-hospital fatality was very low (3 %) but the stay in the ICU tended to be longer than for other types of injury (mean 5.5 ventilation days and 10.7 days in the intensive care unit). Organ failure occurred in 36 % of the cases, multiorgan failure in 29 % and septic events in 14 %. Of the patients 16 % were transferred to another hospital during the first 48 h. The RISC and the updated RISC II tended to underestimate the severity of injuries and mortality (10.2 % vs. 6.8 % and 10.7 % vs. 7.5 %, respectively) and the trauma associated severe hemorrhage (TASH) score underestimated the probability for transfusion of more than 10 units of packed red blood cells (5.0 % vs. 12.5 %). CONCLUSION: This article generates several hypotheses, which should be confirmed with additional investigations. Until then it has to be concluded that patients who suffer from accidental blast injuries in the civilian setting (excluding military operations and terrorist attacks) show a combination of classical severe trauma with blunt and penetrating injuries and additionally a high proportion of severe burns (combined thermomechanical injury). They stay longer in the ICU than other trauma patients and suffer more complications, such as sepsis and multiorgan failure. Established scores, such as RISC, RISC II and TASH tend to underestimate the severity of the underlying trauma.

ABSTRACT

Gunshot wounds are rare in Germany and are mostly the result of suicide attempts or improper handling of weapons. The resulting injuries involve extensive tissue damage and complications which are thus unique and require a differentiated approach. As trauma centers may be confronted with gunshot wounds at any time, treatment principles must be understood and regularly reevaluated. Due to Bundeswehr operations abroad and the treatment of patients from other crisis regions a total of 85 gunshot wounds in 64 patients were treated between 2005 and 2011. In the majority of cases the lower extremities were affected and we were able to carry out treatment to preserve the extremities. In this article we report on our experiences and the results of treatment of gunshot wounds to the lower extremities. This part of the article deals with the epidemiology and pathophysiology of gunshot wounds to the lower extremities. By means of an evaluation of microbiological findings in a subgroup of patients involved in a civil war (n=10), the problem of multidrug resistant pathogen contamination, colonization and infection is discussed. In addition to a description of initial and emergency treatment of gunshot wounds, measures required for further treatment and decontamination are presented. Finally, the results are discussed with reference to the literature in this field.

ABSTRACT

BACKGROUND: Gunshot wounds of the lower extremities are always serious injuries, especially in cases in which bone is affected. Contamination and extensive tissue damage can be life-threatening for the patient and severely affect the function of the extremity. Contamination and local infections with multidrug resistant pathogens are regularly encountered particularly in casualties evacuated from crisis regions. Treatment of this special type of injury, which differs in the form and extent from conventional high-energy trauma of the lower extremities, usually requires lengthy and extensive therapy algorithms in order to preserve the affected extremity. PATIENTS AND METHODS: Based on the results of 34 gunshot wounds of the lower extremities which were surgically treated in this department between 2005 and 2011, this article reports on procedures used for wound management, soft tissue reconstruction and restoration of bone continuity. This group included 18 patients with a total of 20 gunshot-related fractures, 40% of which affected the lower leg and 35% the thigh. The affected extremities could be salvaged in all cases. RESULTS: The therapeutic spectrum required for bone reconstruction after soft tissue coverage demonstrated in these case examples ranged from conventional osteosynthesis with or without local cancellous bone transplant with platelet-rich plasma, to healing in a fixator, bone resection and the Masquelet method, distraction osteogenesis using a fixator in order to restore continuity and definitive secondary extension using an intramedullary skeletal kinetic distractor (ISKD) nail. Out of 15 bullet fractures affecting large tubular bones 8 could be healed without any shortening, axis deviation or malrotation. In 7 cases definitive shortening by an average of 20 mm (minimum 10 mm and maximum 40 mm) was necessary. The average treatment time before full weight-bearing was achieved within tolerable pain limits was 66 weeks (minimum 4 weeks and maximum 267 weeks). Secondary osteitis and osteomyelitis following primary restoration was detected in only one case. CONCLUSION: These results show that the treatment of gunshot wounds of the lower extremities is time-consuming and extensive and requires the complete spectrum of modern trauma surgery. Despite the high risk of complications during treatment it is possible and feasible to apply procedures that preserve the extremities.

ABSTRACT

BACKGROUND: The management of gunshot wounds is a rare challenge for trauma surgeons in Germany and Central Europe as a result of the low incidence of this type of trauma. Penetrating injuries occur with an incidence of 5% in Germany. They are caused by gunshots or more commonly by knives or other objects, for example during accidents. Since even the number of patients who are treated at level 1 trauma centres is limited by the low incidence, the objective of this study was to assess the epidemiology and outcome of gunshot and stab wounds in Germany. MATERIAL AND METHODS: Since 2009, the trauma registry of the German Trauma Society (TraumaRegister DGU®) has been used to assess not only whether a trauma was penetrating but also whether it was caused by a gunshot or a stabbing. On the basis of this registry, we identified relevant cases and defined the observation period. Data were taken from the standard documentation forms that participating German hospitals completed between 2009 and 2011. We did not specify exclusion criteria in order to obtain as comprehensive a picture as possible of the trauma entities investigated in this study. As a result of the high incidence of gunshot wounds to the head and the implications of this type of injury for the entire group, a subgroup of patients without head injuries was analysed. RESULTS: From 2009 to 2011, there were 305 patients with gunshot wounds and 871 patients with stab wounds. The high proportion of suicide-related gunshot wounds to the head resulted in a cumulative mortality rate of 39.7%. Stab wounds were associated with a lower mortality rate (6.2%). Every fourth patient with a gunshot or stab wound presented with haemorrhagic shock, which was considerably more frequently seen during the prehospital phase than during the inhospital phase of patient management. Of the patients with gunshot wounds, 26.9% required transfusions. This percentage was three times higher than that for patients with blunt trauma. CONCLUSION: In Germany, gunshot and stab wounds have a low incidence and are mostly caused by violent crime or attempted suicide. Depending on the site of injury, they have a high mortality and are often associated with major haemorrhage. As a result of the low incidence of these types of trauma, further data and analyses are required which can provide the basis for an evaluation of the long-term quality of the management of patients with stab or gunshot wounds.

ABSTRACT

BACKGROUND: Projectiles or metal fragments can remain lodged in the body of victims of gunshot injuries. This also applies to projectiles which do not tend to deform or fragment on impact. When a projectile fragments on penetration, jacket or lead core particles are likely to remain lodged in the affected region even if the projectile has exited the body. AIM OF THE STUDY: A frequently asked question in the surgical management of such injuries is whether there are medical indications for the surgical removal of projectiles or fragments. MATERIAL AND METHODS: This article presents some typical cases of patients who have received treatment at our institution and reviews the pertinent literature to show general recommendations in special cases concerning the removal of projectiles or fragments and when additional surgical trauma is justified. Parameters for decision making are presented in an algorithm. RESULTS: From our own patients, 5 with remaining fragments in the soft tissue were invited for a clinical follow up. Serum probes and 24 h urine output was analysed for serum lead levels and urinary aminolevulinic acid levels. 74 months (max. 128 - min. 42 months) after injury we documented not elevated serum lead levels of 8.25 µg/ml and urinary aminolevulinic acid levels of 4.8 mg/24 h. DISCUSSION: When lead-containing projectiles or fragments remain lodged in the body, monitoring is required and includes the measurement of serum lead levels and urinary aminolevulinic acid levels. The most important clinical symptoms of lead poisoning are gastrointestinal and neurological in nature. The treatment of choice for lead poisoning is the administration of chelating agents and removal of the lead source by surgical intervention.

ABSTRACT

We report about a successful reconstruction of the first carpometacarpal joint (CMC-joint) of the right hand in a 23 years old man with a posttraumatic defect using the OATS-technique (Osteochondral Autologous Transfer System). 2 autologous osteochondral cylinders with matching surfaces were harvested from the knee joint and implanted in osteoarthritic areas of the CMC-1 joint surface in press fit technique. After primary healing clinical and radiological controls were assessed 6 and 12 weeks postoperatively. At clinical follow-up 1 year after the function of the CMC-1 joint was completely free, function nearly fully restored. The osteochondral grafts revealed a sound healing in an additional MRI-investigation. 3 years after the operation, the DASH-score of the patient was measured with 4.2 points. With view to the encouraging results of the OATS technique in other joints it should be taken into consideration in cases of osteoarthritic CMC-1 joint respecting indicatory limitations.

ABSTRACT

Bomb attacks on the civilian population are one of the primary instruments of global terrorism. Confronted as we are with the increasingly real threat in Europe too, we now have to be constantly prepared for the mass casualties and new injury patterns in trauma care that are caused by terrorist bombings. This is extraordinarily challenging, on both medical and logistical levels, for the hospitals involved. In this review the basic mechanisms of blast injuries are clarified. In addition, the fundamental principles of triage and the management of multiple trauma are presented; these are oriented on ATLS (advanced trauma life support) and DCS (damage control surgery) guidelines. These treatment concepts, which have proved their worth in both military and civilian environments, involve ongoing triage and constant situational assessment and are the basis of improved treatment results in the care of multiply traumatized victims of terrorist bombings.

ABSTRACT

BACKGROUND: Low circulating plasma concentrations of the leukocyte adhesion molecule L-selectin (sCD62L) were found to be associated with an increased risk for subsequent lung failure and case fatality after severe trauma. The objective of this study was to determine the robustness of soluble L-selectin, correcting for a broad spectrum of physiological variables. METHODS: Patients with suspected multiple and/or trunk injuries were enrolled into this study over a 1-year period. Plasma samples were obtained on hospital presentation, and circulating soluble L-selectin was measured with a commercially available ELISA kit. Study records comprised all relevant clinical and laboratory data. Thirty-day survival rate, subsequent acute lung failure, and nosocomial pneumonia were defined as study endpoints. Statistical analysis was performed using multivariate logistic regression models. RESULTS: Seventy patients with a mean age of 35.51 years (range, 10-87 years) and a mean ISS score of 36.61 (95% CI, 31.08-42.14) entered the study. Eleven patients died, leading to an attributable mortality of 15.70%. L-Selectin levels did not differ between survivors and nonsurvivors. Five patients progressed to acute lung injury, whereas 11 patients developed hospital-acquired pneumonia. Lower L-selectin levels indicated patients at risk for lung injury with a relative odds estimated at 4.43 (P = 0.017). Statistical significance diminished in the multivariate model. In contrast, plasma concentrations of circulating sCD62L were significantly decreased in patients developing nosocomial pneumonia (P = 0.023), with a twofold increased relative odds (OR, 1.96; 95% CI, 0.51-7.50). No effect modification was observed by the included covariables. CONCLUSIONS: The results of this study highlight the independent predictive value of initially decreased soluble L-selectin levels for the identification of patients susceptible to subsequent respiratory complications after severe trauma.

ABSTRACT

Normal cells differ from malignant tumor cells in the transcription levels of many different genes. Two colorectal tumor cell lines were compared with a normal colorectal cell line by differential display reverse transcription PCR to screen for tumor cell specific differentially transcribed genes. By this strategy the upregulation of a novel gene was detected designated as 'upregulated in colorectal cancer gene-1' (UCC1). The UCC1 gene transcript level is increased in cultured tumor cells and in two out of three analyzed colorectal tumor tissue specimens compared to normal cultured cells and to corresponding normal tissue samples. Remarkably, the UCC1 protein shows significant sequence similarity to the highly divergent piscine glycoproteins termed ependymins which are synthesized by leptomeningeal fibroblasts and secreted into the cerebrospinal fluid.

ABSTRACT

To identify genes which are differentially transcribed in colorectal tumor cells, we compared the two human tumor cell lines, SW480 and HCT116, with the cell line, NCM460, from normal colon epithelium as a control. Using the methods of differential display reverse transcription PCR and Northern blot hybridization, we detected the differential transcription of seven genes: cholecystokinin, reticulocalbin, Rab5 guanine nucleotide exchange factor Rabex5, caldesmon, differentiation related gene 1 (drg1), taxol resistant associated gene 3 (Trag-3) and the gene for the placental protein, diff33. The yet unidentified cDNA of the human Rabex5 gene and the 3' untranslated region of the human caldesmon gene were cloned.

ABSTRACT

The Min (multiple intestinal neoplasia) mouse with a germline mutation in the adenomatous polyposis coli gene serves as an animal model for familial adenomatous polyposis coli (FAP). The number and age at onset of colorectal adenomas varies in the offspring of Min mice crossed with other strains. The murine gene for the secretory phospholipase A2 (PLA2G2A) was found to be the main candidate for these variations. To test the hypothesis of a correlation between PLA2G2A gene alterations and human tumor development, we screened 14 patients with FAP and 20 patients with sporadic colorectal cancer for germline and somatic PLA2G2A gene mutations. None of the individuals with FAP showed PLA2G2A germline alterations. However, a germline mutation was observed in one patient with an apparently sporadic colorectal tumor; the wildtype allele was somatically lost in the tumor of this patient.

ABSTRACT

Blood normal and tumor tissue samples of 23 patients with sporadic colorectal tumors were screened for DNA alterations in the tumor relevant genes APC, K-ras, DCC and p53. Six different microsatellite regions were analyzed for instability by a new developed non-radioactive method. Somatic DNA alterations were found in 17 tumor samples: 13 carried single or multiple changes in single genes; six carried alterations in microsatellites; two tumors showed tumor suppressor gene mutations in addition to microsatellite changes. We found no indications of correlations between current genetic models of colorectal tumor progression and the established TNM system for histopathological tumor classification.

ABSTRACT

The survival rates of 380 critically ill intensive care patients (> 10 days intensive care, > 3 days mechanical ventilatory support) after gastrointestinal surgery were examined over 1 year following hospital discharge in a retrospective analysis of the years 1984-1994. Of the patients 57% survived intensive care medicine, 54% were discharged from hospital and 44% were still alive 1 year after discharge. Little difference was found between subgroups of gastrointestinal pathology. Of the survivors 28% had psychological problems in the first 6-12 months, 7% showed functional disorders and 3% showed prolonged periods of pain due to intensive therapy.

ABSTRACT

The laparoscopic cholecystectomy of gall bladder carcinoma may have unfortunate consequences because of tumor cell dissemination. In this case report a female patient is presented, where histologically a gallbladder carcinoma was surprisingly diagnosed after laparoscopic cholecystectomy because of symptomatic cholecystectomy. 2 weeks after the first operation tumor cell clusters were found in the laparoscopy tracts.
