The outcome variable was mortality attributed to the disease (MAD). Other variables were: age, sex, comorbidities, focus of origin, waiting time for antibiotic treatment and surgery to start, number of surgical debridement and agents isolated from cultures. Descriptive statistics were used, with calculation of measures of central tendency and dispersion. results: During the study period, 56 patients were identified with diagnosis of Fournier's gangrene (60.7% were male) with a mean age of 52 years (23-75 years old). The MAD was 48.2%. The most common comorbidity was diabetes (66.6%). The more prevalent focus of origin was anorectal pathology (42.9%). The average waiting time from diagnosis to initiation of antibiotic therapy and surgery was 40 minutes and 580 minutes (20-4320), respectively. The required surgical debridement average was 4. Isolated on the intraoperative tissue cultures agent was E. coli (51.8%). conclusion: Mortality attributable to Fournier's gangrene is similar to that observed in the literature.

live donor laparoscopic nephrectomy. experience in 75 casesBackground: Live Donor Laparoscopic nephrectomy (LDLn) has substantial benefits when compared with open nephrectomy such as shorter hospital stay, prompt return to work, less post-operative pain, better cosmetic results, less blood loss and less surgical wound infections. It is the mode of choice for safely harvesting a kidney for organ transplantation. aim: To describe the surgical results of LDLn in a pioneer renal transplant center in Chile. material and methods: Review of clinical records of 75 subjects aged 27 to 60 years (37 males) subjected to a LDLn in a public hospital between 1998 and 2013. Information about clinical and surgical data and perioperative complications was retrieved. results: no subject died. All kidneys were satisfactorily implanted in their receptors. The mean operative time was 116 minutes. Mean hospital stay was 1.6 days, warm ischemia time was 6.8 minutes, and cold ischemia time was 31.5 minutes. Operative adverse events occurred in 8%. The conversion and reoperation rates were 4 and 1.3%, respectively. Among receptors, 1.5% evolved with Acute Tubular necrosis and 2.2% required graft excision. conclusions: LDLn is a safe and pioneering surgical technique in Chile. Its results are satisfactory and comparable to those obtained with classic lumbotomy.

Penetrating neck trauma aim: The aim of this study is to report the surgical outcomes in a series of patients undergoing to exploratory cervicotomy by penetrating neck trauma (PnT) in emergency department of Barros Luco-Trudeau Hospital (BLTH), between 2003 and 2013, in terms of postoperative morbidity (POM). matherial and methods: Retrospective case series of patient undergoing exploratory cervicotomy in emergency department of BLTH, between 2003 and 2013. The outcome variable was development of POM. Other variables were age, sex, etiology and kind of injury, hemodynamic status at admission, surgical time, distribution of injuries by anatomic areas, need for re operation and intra and post operative mortality. Descriptive statistics were used. results: During the study period, 59 exploratory cervicotomies were performed to patients with PnT, with an average age of 32,5 years old. 89,8% of patients were male. The POM was 33,4%, being the most frequent the neurological ones. The most frequent etiology was the stab with 83%. 66% of patients were hemodynamically unstable at admission. Mean operative time was 107 minutes. The most injured area was the area II. conclusion: The PnT is a little prevalent disease. The outcomes of our study are consistent with those reported in the literature.
