RESUMO
Necrotizing fasciitis is one of the most dangerous complication of an abscess and it is still a disease with a high mortality. In this work, we decided to consider two cases: the first one concerns a male subject, aged 66, deceased because of a fatal necrotizing fasciitis associated to a cervical descending mediastinitis, which evolved from a primary peritonsillar abscess; the second is about a 50-year-old woman with a perineal abscess, then evolved into necrotizing fasciitis associated to a fatal septis shock. After a systematic consideration of necrotizing fasciitis as pathology and an analysis of the possible related risks to a diagnostic or therapeutic delay, we analyzed the particular history of both cases to underline the possible critical issues in professional behavior of the medical staff intervened. KEY WORDS: Abscess, Medical malpractice, Mortality, Necrotizing fasciitis, Professional liability.

BACKGROUND AND STUDY AIMS: The overall diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for subepithelial lesions (SELs) is suboptimal. The aim of this study was to evaluate the diagnostic accuracy, defined as the proportion of correct diagnoses, obtained using the EUS-guided fine-needle tissue acquisition (FNTA) sampling technique performed with the newly developed forward-viewing EUS scope (FV-EUS). PATIENTS AND METHODS: This was a retrospective analysis of a prospectively collected database including all consecutive patients with SELs who underwent EUS-FNTA using the FV-EUS scope from 2007 to 2011 in a tertiary referral center. All procedures were performed by a single expert endoscopist. RESULTS: A total of 121 consecutive patients with SELs (13 in the esophagus, 96 in the stomach, 10 in the duodenum, 2 in the rectum) underwent sampling of the lesion using the FV-EUS scope. The procedure was technically feasible in all but one patient, and no complication related to EUS-FNTA occurred. Full histological assessment including immunostaining could be completed in 93.4% (113/121) of the patients. Considering neoplastic vs. non-neoplastic diseases, the sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were 92.8% (95%CI 86.3-96.8), 100% (95%CI 69.0-100%), infinity, and 0.07 (95%CI 0.04-0.14), respectively. CONCLUSIONS: EUS-FNTA performed in conjunction with the FV-EUS scope for sampling SELs of the gastrointestinal tract was safe and provided a very high diagnostic accuracy. Studies comparing FV-EUS with standard curved linear echoendoscopes are needed to clarify whether these results are due to the sampling technique or the type of scope utilized.
