AbstractTumours of the appendix are rare and tend to be diagnosed incidentally, in cases of acute appendicitis. For some authors, appendiceal neuroendocrine tumours (ANETs) are the most frequent neoplasm of the appendix, observed in 0.3% to 0.9% of cases acute appendicitis. The present is a unicentric retrospective study conducted between January 2005 and March 2017. Out of a total of 3,007 surgeries for appendiceal pathologies performed in the adult population at the hospital where the present study was conducted, there were 70 (2.33%) malignant cases, 20 (28.6%) of which were ANETs. The patients had a median age of 44 years (range: 18 to 85 years), and were predominantly women (there were 1.9 times more women than men). In 16 cases (80%), a simple appendicectomy was performed (1 patient was submitted to a right hemicolectomy later). The cases of ANETs had a good prognosis in our series: 85% of the patients are either alive today or were alive after 5 years of follow-up. Despite the fact that ANETs are described as the most frequent tumor of the appendix, this was not confirmed in our series, in which they only represented 28.6% of the cases; adenocarcinoma was the most frequent tumor (65.7%) among our sample.

Negative Appendectomy Rate

(1) Background: Diagnosis of acute appendicitis (AA) remains challenging; either computed tomography (CT) is universally used or negative appendectomy rates of up to 30% are reported. Transabdominal ultrasound (TUS) as the first-choice imaging modality might be useful in adult patients to reduce the need for CT scans while maintaining low negative appendectomy (NA) rates. The aim of this study was to report the results of the conditional CT strategy for the diagnosis of acute appendicitis. (2) Methods: All patients suspected of acute appendicitis were prospectively registered from 1 January 2016 to 31 December 2018. Data on their clinical, radiological and surgical outcomes are presented. (3) Results: A total of 1855 patients were enrolled in our study: 1206 (65.0%) were women, 649 (35.0%) were men, and the median age was 34 years (IQR, 24.5–51). TUS was performed in 1851 (99.8%) patients, and CT in 463 (25.0%) patients. Appendices were not visualized on TUS in 1320 patients (71.3%). Furthermore, 172 (37.1%) of 463 CTs were diagnosed with AA, 42 (9.1%) CTs revealed alternative emergency diagnosis and 249 (53.8%) CTs were normal. Overall, 519 (28.0%) patients were diagnosed with AA: 464 appendectomies and 27 diagnostic laparoscopies were performed. The NA rate was 4.2%. The sensitivity and specificity for TUS and CT are as follows: 71.4% and 96.2%; 93.8% and 93.6%. (4) Conclusion: A conditional CT strategy is effective in reducing NA rates and avoids unnecessary CT in a large proportion of patients. Observation and repeated TUS might be useful in unclear cases.

Introduction: Acute appendicitis in children is the most common acute surgical condition in children. Each year, 80000 children in the United States suffer from appendicitis. Objectives: The aim of this study was to evaluate diagnostic value of neutrophil to lymphocyte ratio (NLR) in younger and older pediatrics suspect of acute appendicitis in Imam Hossein hospital. Patients and Methods: This was a retrospective study conducted at Imam Hossein hospital from 2015-2017. The study population was all children with suspected appendicitis who refer to Imam Hossein medical center in Isfahan. The sample size was 423 people. The collected data were imported into SPSS software version 22 and analyzed with appropriate statistical tests. The significance level in the present study was less than 0.05. Results: The average age of participants was 7.2 ± 3.8 years. In both study groups, it was observed that the mean NLR in the normal and reactive follicular groups was significantly lower than the appendicitis and complication groups (P<0.05). The results of the present study showed that NLR diagnostic test can be a good predictor for the evaluation of appendicitis in both groups under 4 years and over 4 years. For more than 4 years’ group; AUC=0.74, P<0.001 and for less than 4 years’ group; AUC=0.69, P<0.001. For less than 4 years’ group, the cut-off score for appendicitis diagnosis was 2.3. In this cut-off, the sensitivity and specificity were equal to 0.65% and 0.72%. Additionally, for more than 4 years’ group, the cut-off for the diagnosis of appendix was 3.5. In this cut-off, the sensitivity and specificity were equal to 0.73% and 67%. Conclusion: This analysis demonstrates that NLR, in the context of appropriate clinical assessment of patients with a high a priori probability of appendicitis, has a greater diagnostic accuracy in supporting the diagnosis of appendicitis.
