RESUMO

BACKGROUND: Although there is a rationale supporting that preoperative showering with 2% or 4% chlorhexidine gluconate (CHG) would decrease skin bacterial colonization, there is no consensus that this practice reduces the risk of surgical site infection (SSI). OBJECTIVES: Analyze the skin concentration of CHG after preoperative showering associated with the traditional skin preparation with CHG 4% for breast surgery. METHODS: Randomized controlled trial that included 45 patients, all candidates for augmentation mammaplasty, allocated into three groups (A: no preoperative showering; B: one preoperative showering; C: two preoperative showering with CHG 4%) in a 1:1:1 ratio. Skin swabs collection was performed right before the surgical incision. The samples were, then, sent to spectrophotometry in order to determine the skin concentration of CHG at the beginning of surgery. RESULTS: The age ranged from 18 to 61 years, with a mean of 37 years old. Group C had the lowest median concentration (0.057) followed by group B (0.060) and group A (0.072), however, with no statistical significance. The areola was the place with the lowest median concentration level (0.045), followed by the axilla (0.061) and the inframammary fold (IMF) (0.069). Still, when comparing the distribution of the sites, a statistically significant difference was found only between the axilla and the areola (p = 0.022). CONCLUSION: Preoperative showering with CHG 4% did not increase the concentration of this agent on the skin surface right before the surgical incision.

RESUMO

BACKGROUND: Autologous fat graft is often employed to treat body contour defects. There is currently increased interest in the regenerative properties of fat grafting. OBJECTIVES: The authors evaluated the histological changes of fat grafting in a blinded randomized controlled trial of staged fat grafting-abdominoplasty. METHODS: Ten women between 24 and 55 years of age with a body mass index <30 kg/m2 and previous cesarean scar were submitted to fat grafting followed by staged abdominoplasty. The C-section scar served as a landmark for standardization of fat grafting site and control. One side of the abdomen was fat grafted and the other was left intact (control). At the time of abdominoplasty, 4 months later, a full-thickness skin sample from each hemi abdomen (fat-grafted area and control) was collected and sent to histological analysis. RESULTS: All of the fat-grafted samples showed extracellular lipids and signs of fat graft viability, whereas no such changes occurred in the control group. There were no statistically significant differences in fat-grafted vs control samples regarding skin inflammatory infiltrate (P = 0.582), dermis thickness (P = 0.973), vascular density (P = 0.326), and amount of elastic fibers (P = 1). CONCLUSIONS: The histological evaluation of women's abdominoplasty surgical site skin after 4 months of fat grafting showed signs of fat graft in 100% of the grafted sides but no change in skin inflammatory infiltrate, dermis thickness, vascularity density, or elastic fiber quantity.

RESUMO

OBJECTIVE: To demonstrate the feasibility of endoscopic extraperitoneal single site (EESS) inguinal hernia repair and compare it outcomes with the conventional totally extraperitoneal (TEP) technique. BACKGROUND: TEP inguinal hernia repair is a widely accepted alternative to conventional open technique with several perioperative advantages. Transumbilical laparoendoscopic singlesite surgery (LESS) is an emerging approach and has been reported for a number of surgical procedures with superior aesthetic results but other advantages need to be proven. PATIENTS AND METHODS: Thirty-eight uncomplicated inguinal hernias were repaired by EESS approach between January 2010 and January 2011. All procedures were performed through a 25 cm infraumbilical incision using the Alexis wound retractor attached to a surgical glove and three trocars. Body mass index, age, operative time, blood loss, complications, conversion rate, analgesia requirement, hospital stay, return to normal activities and patient satisfaction with aesthetic results were analysed and compared with the last 38 matched-pair group of patients who underwent a conventional TEP inguinal hernia repair by the same surgeon. RESULTS: All procedures were performed successfully with no conversion. In both unilateral and bilateral EESS inguinal repairs, the mean operative time was longer than conventional TEP (55± 20 vs. 40± 15 min, P = 0.049 and 70± 15 vs. 55± 10 min, P = 0.014). Aesthetic result was superior in the EESS group (2.88± 0.43 vs. 2.79± 0.51, P = 0.042). There was no difference between the two approaches regarding blood loss, complications, hospital stay, time until returns to normal activities and analgesic requirement. CONCLUSION: EESS inguinal hernia repair is safe and effective, with superior cosmetic results in the treatment of uncomplicated inguinal hernias. Other advantages of this new technique still need to be proven.
