Are females predisposed to complications in head and neck cancer free flap reconstruction?

PURPOSE: To investigate gender and other possible factors affecting the frequency and severity of postoperative complications in head and neck cancer free flap reconstruction. MATERIALS AND METHODS: A prospective longitudinal cohort study was conducted at the Greek Anticancer Institute, St. Savvas Hospital in head and neck cancer free flap reconstruction concerning postoperative complications. We documented the patients' demographic characteristics, social habits, and perioperative factors (ie, duration of general anesthesia), reconstructive techniques, neoadjuvant radiotherapy, and physical status. Initially, univariate statistical analysis was performed to confirm which predictor variables might influence the presence and severity of complications. Next, multivariate statistical analysis was performed using logistical regression and including the factors that were statistically significant on univariate analysis. RESULTS: From 1999 to 2009, we assessed 95 patients who had undergone surgery for head and neck cancer. Of the 95 patients, 24 were women and 71 were men. The patient age range was 20 to 87 years (mean 52, median 55). A total of 55 complications occurred in 49 patients (51.57%). Of the 55 complications, 12 (12.63%) were of major severity, 21 (22.10%) of median severity, and 22 (23.15%) of low severity. The statistical analysis revealed that the factors associated with complications were preoperative radiotherapy, female gender, and operation time. The factors associated with severe complications were female gender and alcohol use. CONCLUSIONS: Multivariate analysis of the data revealed that the factor associated with an increased incidence of postoperative complications was preoperative radiotherapy. Moreover, the variable that remained statistically significant and correlated with an increased incidence and severity of free flap reconstruction complications was female gender. Identifying the etiology of these findings is an intriguing field for additional research.

Management of a complicated ruptured infected pseudoaneurysm of the femoral artery in a drug addict.

Infected pseudoaneurysm of the femoral artery represents a devastating complication of intravenous drug abuse, especially in the event of rupture. Operative strategy depends upon the extent of arterial injury and the coexistence of infection or sepsis. Options range from simple common femoral artery (CFA) ligation to complex arterial reconstruction with autologous grafts (arterial, venous, or homografts). We report herein the management of a 29-year-old male patient who was urgently admitted with a ruptured pseudoaneurysm of the right CFA, extending well above the inguinal ligament. Multidisciplinary approach with multiple arterial reconstructions and subsequent coverage of the tissue defect with a rectus abdominis musculocutaneous flap transposition was performed.

Evaluation of the effects of laparotomy and laparoscopy on the immune system in intra-abdominal sepsis--a review.

This review portrays the most common experimental models of intra-abdominal sepsis. Additionally, it outlines the facts that distinguish laparotomy from laparoscopy, in respect to the immune response, when comparing these two techniques in experimental models of intra-abdominal sepsis. It describes the consequences of pneumoperitoneum and trauma produced by laparoscopy or laparotomy, respectively, on bacterial translocation and immunity. Furthermore, we report the few efforts that have been made in clinical settings, where surgeons have attempted to utilize laparoscopy as a therapeutic module when treating peritonitis or sepsis of abdominal origin. Certainly there is a need for more research in order to fortify the role of pneumoperitoneum in sepsis of abdominal origin. It seems that minimally invasive surgery will inevitably gain acceptance by surgeons, as evidence points that by inflicting less trauma the healing response is expected to be more efficient, especially in septic patients.
