RESUMO

INTRODUCTION: Prompt appendectomy has long been the standard of care for acute appendicitis in order to prevent complications such as perforation, abscess formation, and diffuse purulent or fecal peritonitis, all resulting in increased morbidity and even mortality. Our study was designed to examine whether the time from the beginning of symptoms to operation correlates with the pathological degree of appendicitis, incidence of postoperative complications, or increased length of hospital stay. METHODS: A prospective study of 171 patients who underwent emergent appendectomy for acute appendicitis in the course of 2 years was conducted in a single tertiary medical center. The following parameters were monitored and correlated: demographics, time from the onset of symptoms until the arrival to the emergency department (patient interval (PI)), time from arrival to the emergency department (ED) until appendectomy (hospital interval (HI)), time from the onset of symptoms until appendectomy (total interval (TI)), physical examination, preoperative physical findings, laboratory data, pathologic findings, complications, and length of hospital stay. RESULTS: The degree of pathology and complications were analyzed according to the time intervals. The time elapsed from the onset of symptoms to surgery was associated with higher pathology grade (p = 0.01). We found that longer time from the onset of symptoms to hospital arrival correlates with higher pathology grade (p = 0.04), while there was no correlation between the hospital interval and pathology grade (p = 0.68). A significant correlation was found between the pathology grade and the incidence of postoperative complications as well as with increased length of hospital stay (p = 0.000). CONCLUSION: Time elapsed from the symptom onset to appendectomy correlates with increased pathology grade and complication rate. This correlation was not related to the HI. Since the HI in our study was short, we recommend an early appendectomy in adults in order to shorten the TI and the resulting complications.

RESUMO

BACKGROUND: Limited contemporary data exist regarding the incidence, predictors, and outcomes of failure of primary percutaneous coronary intervention (PCI) in the treatment of ST-segment elevation myocardial infarction (STEMI). MATERIALS AND METHODS: In this registry-based retrospective cohort study, all consecutive unselected patients (n=1725) who were hospitalized for STEMI and underwent primary PCI from January 2001 to December 2010 were included. PCI failure was defined as a final diameter stenosis greater than 30% or postdilatation Thrombolysis in Myocardial Infarction (TIMI) flow grade of 2 or less. We examined the predictors and survival among patients who failed primary PCI. RESULTS: The overall PCI failure rate was 5.4% (94 of 1725 procedures). After adjusting for prespecified baseline characteristics, independent predictors of PCI failure included age greater than 65 years (P=0.02), procedure date between 2001 and 2005 (P=0.05), night-time PCI (P=0.008), calcific lesion (P=0.008), and lower preprocedural TIMI flow grade (P=0.006). Failed PCI was associated with a 1-year mortality rate of 22% as compared with 4.2% in the successful PCI group (P<0.001). Conservative medical management was preferred in the majority of patients with failed PCI (n=78, 83%). Patients who underwent emergent surgery (n=11), conservative management (n=78), and redo PCI (n=5) experienced 30-day mortality rates of 27, 16, and 0%, respectively. CONCLUSION: Primary PCI failure in the setting of STEMI is not rare. It is associated with high-risk patient-related and angiographic-related characteristics. Primary PCI failure is associated with early and late mortality.
