RESUMEN
The management of chronic pilonidal disease remains controversial, but recently, new minimal invasive approaches have been proposed. Whereas in the conventional surgical treatment an elliptical wedge of skin and subcutaneous tissue is created to remove the sinus and its lateral tracks, the basis for our new treatment is to create a minimal elliptical wedge of the subcutaneous tissue, including all the inflamed tissue and debris while leaving the overlying skin intact. The mechanism of an endoscopic approach relies on use of the endoscope without cutaneous tissue damage. Advantages include shorter operative time and time to discharge, which impact resource management in both primary and secondary care: patients undergoing endoscopic technique have a high satisfaction rate, probably due to the low level of postoperative pain and early return to work and daily activities. However, it is mandatory that further studies would analyze surgical approaches to pilonidal sinus disease (PSD) with a consistent and adequate follow-up of at least 5 years. Both sinusectomy and endoscopic approach to PSD were found to be safe and effective compared with conventional techniques. Publishedresults of studies of newer approaches have demonstrated a low short-term complication rate, comparable to conventional surgery results.
RESUMEN
We focused our attention on susceptibility profile of Acinetobacter spp., Pseudomonas spp., and Klebsiella spp. isolated from biological specimens at the University Hospital of Salerno between June 2011 and October 2012. Acinetobacter, with a prevalence of Acinetobacter baumannii (97%) presented a high range of resistance to the antimicrobials considered, excluding colistin (COL). Klebsiella spp. isolates, with a prevalence of Klebsiella pneumoniae (90%), presented a variable pattern of resistance [from 9·8% for COL to 50% for levofloxacin (LEV)]. Extended-spectrum beta-lactamases production was detected in 15% of isolates. Most Pseudomonas isolates were P. aeruginosa with a high rate of resistance (95% to amoxicillin/clavulanate and trimethoprim/sulfamethoxazole, and <50% to the other antibiotics). Colistin remained the most effective drug tested. This study provided useful information of the local bacterial epidemiology hopefully permitting to establish a more effective empirical therapy, preventing the inappropriate use of antibacterial agents and possibly limiting the diffusion of antibacterial resistance.
