Necrotising fasciitis is a rare but disastrous complication after elective surgery. We present two patients (both male, 58 and 18 years old) who developed necrotising fasciitis following elective inguinal hernia repair according to Lichtenstein. The importance of both recognition and time interval between symptom occurrence and surgical intervention is illustrated, emphasising the need for immediate action when necrotising fasciitis is suspected. A high index of suspicion of necrotising fasciitis should be maintained when a wound infection is accompanied by disproportional pain, lethargy, or sepsis. Epidermolysis and subcutaneous emphysema are often very late symptoms. Recognition and immediate intervention decrease mortality and morbidity.

Purpose For the diagnosis of acute appendicitis, the combination of clinical and laboratory variables achieves high diagnostic accuracy. Nevertheless, appendicitis can present with normal laboratory tests of inflammation. The aim of this study was to investigate the incidence of normal inflammatory markers in patients operated for acute appendicitis. Methods This is an analysis of data from a prospective, multicentre SNAPSHOT cohort study of patients with suspected acute appendicitis. Only patients with histopathologically proven acute appendicitis were included. Adult patients with acute appendicitis and normal preoperative inflammatory markers were explored further in terms of abdominal complaints, preoperative imaging results and intraoperative assessment of the degree of inflammation and compared to those with elevated inflammatory markers. Results Between June and July 2014, 1303 adult patients with histopathologically proven acute appendicitis were included. In only 23 of 1303 patients (1.8%) with proven appendicitis, both preoperative white blood cell count and C-reactive protein levels were normal. Migration of pain was reported less frequently in patients with normal inflammatory markers compared to those with elevated inflammatory marker levels (17.4% versus 43.0%, p = 0.01). Characteristics like fever, duration of symptoms and localized peritonitis were comparable. Only 4 patients with normal inflammatory markers (0.3% overall) had complicated appendicitis at histopathological evaluation. Conclusion Combined normal WBC and CRP levels are seen in about 2 per 100 patients with confirmed acute appendicitis and can, although rarely, be found in patients with complicated appendicitis.
