Aim: Diagnostic error can result in the appendectomy of a normal appendix, commonly known as negative appendectomy (NA). Missed appendicitis (MA) is related to a poor outcome. The aim of this study was to determine whether there are factors in presentation associated with NA or MA.

Purpose: This study evaluates the effectiveness of machine learning (ML) algorithms for improving the preoperative diagnosis of acute appendicitis in children, focusing on the accurate prediction of the severity of disease.
Methods: An anonymized clinical and operative dataset was retrieved from the medical records of children undergoing emergency appendectomy between 2014 and 2021. We developed an ML pipeline that pre-processed the dataset and developed algorithms to predict 5 appendicitis grades (1 - non-perforated, 2 - localized perforation, 3 - abscess, 4 - generalized peritonitis, and 5 - generalized peritonitis with abscess).

Purpose: Neuroendocrine neoplasms of the appendix (aNET) are rare tumors that are often diagnosed by pathology as an incidental finding after appendectomy for acute appendicitis. Several guidelines proposed risk criteria to indicate oncological completion surgery after appendectomy. The aim of this study was to evaluate the reliability of proposed criteria for completion surgery of aNET.

Background: Randomised controlled trials (RCTs) have found antibiotics to be a feasible and safe alternative to appendicectomy in adults with imaging-confirmed acute appendicitis. However, patient inclusion criteria and outcome definitions vary greatly between RCTs. We aimed to compare antibiotics with appendicectomy for the treatment of acute appendicitis using individual patient data and uniform outcome definitions.

Background: There is no consensus on the appropriate duration of postoperative antibiotics for complicated appendicitis in children. Commonly used antibiotic endpoints include normalization of white blood cell count (WBC) or completion of a minimum number of prespecified treatment days. We compared clinical outcomes resulting from varying postoperative antibiotic protocols for complicated appendicitis in children.
