    Corona mortis: in vivo anatomical knowledge and the risk of injury in totally extraperitoneal inguinal hernia repair
    (Springer, 2016) Ates, M.; Kinaci, E.; Kose, E.; Soyer, V.; Sarici, B.; Cuglan, S.; Korkmaz, F.
    Corona mortis (CMOR) is the arterial and/or venous vascular communication(s) between the obturator and external iliac vessels. Totally extraperitoneal (TEP) inguinal hernioplasty can be associated with vascular complications especially during the fixation of the mesh. Theoretically, CMOR is an important nominee. But, the data in literature are insufficient about CMOR injury. Additionally, most of the studies about CMOR have been usually performed on cadavers. We aimed to reveal the preperitoneal vascular anatomy of inguinal area and provide in vivo knowledge about CMOR. The risk of arterial injury was also evaluated. The data of preperitoneal vascular anatomy of 321 patients who underwent TEP procedure between January 2005 and July 2014 were retrospectively evaluated. Mean age was 46 +/- 8.9 years, 53 females vs 268 males. 391 hemipelvises were evaluated. Two types of arterial structure were identified; (1) an aberrant obturator artery forming an anastomosis with branches of ordinary obturator artery; (2) a pubic branch of inferior epigastric artery. The incidence of arterial CMOR was 28.4 % and of any arterial structure was 45.0 %. An arterial CMOR was considered as thick (aeyen2 mm) or thin (< 2 mm). Injury of arterial CMOR during tack stapling on Cooper's ligament was seen in six cases (1.5 %). All of them were thin (< 2 mm) in structure. Venous CMOR was visible only under low pressure in work space. During TEP hernia repair, CMOR and/or pubic branch of inferior epigastric artery can be damaged. To prevent this complication, tacks should be stapled to Cooper's ligament close to symphysis pubis and dissection should be careful on the posterior surface of superior pubic ramus. Small caliber (< 2 mm) arterial CMOR is more prone to be injured during TEP procedure. To explore venous structures properly, pressure in workspace should be kept as low as possible.

    Rapid Detection of Bloodstream Pathogens in Liver Transplantation Patients With Film Array Multiplex Polymerase Chain Reaction Assays: Comparison With Conventional Methods
    (Elsevier Science Inc, 2015) Otlu, B.; Bayindir, Y.; Ozdemir, F.; Ince, V.; Cuglan, S.; Hopoglu, M.; Yakupogullari, Y.
    Background. Bloodstream infection (BSI) is an important concern in transplant patients. Early intervention with appropriate antimicrobial therapy is critical to better clinical outcome; however, there is significant delay when conventional identification methods are used. Methods. We aimed to determine the diagnostic performance of the FilmArray Blood Culture Identification Panel, a recently approved multiplex polymerase chain reaction assay detecting 24 BSI pathogens and 3 resistance genes, in comparison with the performances of conventional identification methods in liver transplant (LT) patients. A total of 52 defined sepsis episodes (signal-positive by blood culture systems) from 45 LT patients were prospectively studied. Results. The FilmArray successfully identified 37 of 39 (94.8%) bacterial and 3 of 3 (100%) yeast pathogens in a total of 42 samples with microbial growth, failing to detect only 2 of 39 (5.1%) bacterial pathogens that were not covered by the test panel. The FilmArray could also detect additional pathogens in 3 samples that had been reported as having monomicrobial growth, and it could detect Acinetobacter baumannii in 2 samples suspected of skin flora contamination. The remaining 8 blood cultures showing a positive signal but yielding no growth were also negative by this assay. Results of MecA, KPC, and VanA/B gene detection were in high accordance. The FilmArray produced results with significantly shorter turnaround times (1.33 versus 36.2, 23.6, and 19.5 h; P < .05) than standard identification methods, Vitek II, and Vitek MS, respectively. Conclusions. This study showed that the FilmArray appeared as a reliable alternative diagnostic method with the potential to mitigate problems with protracted diagnosis of the BSI pathogens in LT patients.
