title: [Adverse outcomes in the surgical treatment of acute appendicitis].
abstract: OBJECTIVE
  To describe adverse outcomes after appendectomy for acute appendicitis and to analyze the association between these outcomes and specific characteristics of the patient and hospital admission.
  
  
  METHODS
  We studied a cohort of 792 patients who underwent appendectomy for acute appendicitis. Postoperative complications, reoperations and deaths were prospectively studied and all readmissions were retrospectively identified. Logistic regression was used to evaluate the relationship between complications and patient characteristics, as well as hospital admission.
  
  
  RESULTS
  Postsurgical complications developed in 9.8% of the patients. These complications mainly consisted of surgical wound infection (4.2%) and intra-abdominal complications (2.1%). A total of 0.7% of patients underwent reoperation during admission, 0.5% were admitted to the intensive care unit and five patients (0.6%) died in hospital. The rate of operation-related readmissions in the following year was 3.2%. Length of hospital stay was longer in patients with complications than in those without complications (9.6 and 3.5 days, respectively). Postoperative complications were associated with older age (45-65 years, OR 3.62, p < 0.001; more than 65 years OR 8.68, p < 0.001) and acute appendicitis complicated with peritonitis or perforation (OR 3.69, p < 0.005). Readmissions related to previous surgery were associated only with complications during the first admission (OR 18.79, p < 0.001).
  
  
  CONCLUSIONS
  In appendectomy, the most frequent adverse outcomes are surgical wound infection and intra-abdominal complications, which are associated with older patients and perforations. This subgroup of patients at high risk requires closer surveillance.
