ObjectiveHilar cholangiocarcinoma is the fourth most common gastrointestinal malignancy. CA19-9 and CEA are helpful devices in the management of gastrointestinal malignancies and belong to clinical routine in surgical oncology. But the validity of these parameters in terms of tumor extension and prognosis of bile duct malignancies still remains unclear.MethodsFrom 1998 to 2008, we obtained preoperative CA19-9 and CEA serum levels in 136 patients with hilar cholangiocarcinoma. We correlated tumor stage, resectability rate and survival with preoperative CA 19-9 and CEA serum levels.ResultsCA19-9 (UICC I: 253 ± 561 U/ml; UICC II: 742 ± 1572 U/ml; UICC III: 906 ± 1708 U/ml; UICC IV: 1707 ± 3053 U/ml) and CEA levels (UICC I: 2.9 ± 3.8 U/ml; UICC II: 4.6 ± 6.5 U/ml; UICC III: 18.1 ± 29.6 U/ml; UICC IV: 22.7 ± 53.9 U/ml) increase significantly with rising tumor stage. Patients with pre operative serum levels of CA19-9 (> 1000 U/ml) and CEA (> 14.4 ng/ml) showed a significant poorer resectability rate and survival than patients with lower CA19-9 and CEA serum levels respectively.ConclusionCA19-9 and CEA serum levels are associated with the tumor stage. If preoperatively obtained CA19-9 and CEA serum levels are highly elevated patients have an even worse survival and the frequency of irresectability is significantly higher.

Visceral artery aneurysms are rare with an incidence of only 0.01–0.1% of the population. Open surgical or endovascular elimination should be performed for aneurysms greater than 2 cm in size. The risk of aneurysm rupture is then approximately 25–40%. If the aneurysm ruptures the mortality can be as high as 76%. For mycotic aneurysms or spurious aneurysms there is no lower limit to the diameter size for the need of treatment. Sudden abdominal pain during pregnancy can be caused by visceral artery aneurysms and must be further clarified. The indications for surgery during pregnancy should be made generously. The clinical symptoms (abdominal complaints) of visceral artery aneurysms are manifold. The treatment can be either an open surgical approach or endovascular treatment. In the emergency setting, if endovascular treatment is no longer possible, an open surgical treatment needs to be performed. There are so far no randomized studies which could identify one of the procedures (open surgery vs. endovascular surgery) as clearly being superior. The prognosis after treatment is satisfactory with a 5–10 year survival rate of approximately 90%.

Introduction. Most investigations on autoimmune pancreatitis (AIP) were published on Asian cohorts while those on Caucasians are limited. However, there might be differences related to the origin. Patients and Methods. We analyzed 36 patients and compared type 1 (AIP1) with type 2 (AIP2). Results. The majority of patients suffered from AIP1 (55.6%). AIP1 patients were significantly older than AIP2 patients (54.4 versus 40.8 years). Moreover, 85.0% of AIP1 patients had concurrent autoimmune cholangitis (AIC) while 18.8% of AIP2 patients suffered from overlap to ulcerative colitis (UC). However, AIP1 patients revealed a cholestatic course and had significantly higher immunoglobulin G4 levels (IgG4). When compared to allele frequencies in healthy controls, in patients with AIP1 HLA-B8 reached statistical significance. Response to steroids was excellent in both groups, but we noticed high rates of relapse especially in AIP1 patients. Finally, 3 patients with AIP1 were diagnosed with cholangiocellular carcinoma (CCC). Conclusion. In contrast to Asian studies, we found an almost equal distribution of AIP1 and AIP2 patients in our German cohort. AIP2 patients were younger and mostly of female gender whereas AIP1 patients revealed higher IgG4 levels and involvement of the biliary tract in sense of IgG4-associated cholangitis.

Exact data regarding the clinical role of maggot debridement therapy (MDT) for wound care in a specific country are not available. Thus, we analysed the use of MDT in hospitalised patients in Germany. Detailed lists of all hospitalised cases treated with MDT in Germany for the years 2011 to 2016 were provided by the Federal Statistical Office as well as the lists of the 15 most frequent principal and additional diagnoses, respectively, and the 10 most frequent procedures documented with MDT in 2016. Within the 6-year time period of the study, the number of cases treated with MDT increased by 11% from 4513 in 2011 to 5.017 in 2016. Lower leg and foot were the most frequent anatomic sides of treatment counting up to 83.9% of all cases. In addition, MDT procedures for temporary soft tissue coverage including negative pressure wound therapy were often performed: for treatment of large areas in 36.7% and small areas in 6.2%. 41.3% of all cases treated with MDT had infection with Escherichia coli and 35.9% of all cases with Bacillus fragilis. Our analysis shows a limited use of MDT with a small increase only in the last 6 years in German hospitals. MDT is predominately used to treat foot or leg ulcers.

Bacterial infections are the main cause of death within the first year after liver transplantation, and the increased incidence of multidrug-resistant gram-positive pathogens has created a major challenge in the treatment of these patients. Linezolid, the first US Food & Drug Administration-approved oxazolidinone, offers a valuable novel treatment option for serious gram-positive infections. Linezolid is relatively non-toxic but prolonged treatment with linezolid was associated with thrombocytopenia. Here we report on the experience of linezolid treatment in adult liver transplant patients, who are at an increased risk for thrombocytopenia because of hypersplenism. From November 2003 until December 2009, we evaluated the clinical course of 46 liver transplant patients (27 male/19 female) in our surgical intensive care unit. For proven or probable gram-positive infection, all patients received linezolid 600 mg intravenously every 12 h. On clinical improvement, treatment was changed to oral linezolid 600 mg twice daily. Treatment duration was 11 ± 7 days. Treatment indications were pneumonia (n = 8), blood stream infection (n = 30), and surgical site/abdominal infection (n = 3). Clinical cure was achieved in 43 out of 46 patients. During the course of treatment, no cases of severe thrombocytopenia occurred and a statistically significant platelet count increase was seen from day 1 (110 ± 73/nL) to day 7 (165 ± 116/nL) and day 14 (180 ± 140/nL). We did not observe any further adverse events, especially no severe neurological complications (e.g., serotonin syndrome) or signs of lactate acidosis. Two patients died from uncontrolled vancomycin-resistant Enterococcus faecium sepsis with septic shock and one due to uncontrolled methicillin-resistant Staphylococcus aureus pneumonia. These deaths were considered to be unrelated to linezolid treatment, and linezolid was regarded as the optimal treatment choice in these patients. A subgroup analysis of patients treated for >14 days revealed no statistically significant differences when compared with patients on shorter treatment. In particular, no cases of thrombocytopenia occurred during longer treatment. In conclusion, linezolid is a safe and effective treatment for adult liver transplant patients with gram-positive infections.
