RESUMEN
INTRODUCTION: Abdominal wall hernias are a frequent cause of abdominal pain-related emergency department visits. Our study aimed to establish the connection between lactate levels and patient outcomes in those with abdominal pain due to abdominal wall hernias. MATERIALS AND METHODS: Our research followed a retrospective, observational, and descriptive approach and two center. We included patients who visited the emergency department for abdominal pain and were confirmed to have abdominal wall hernias through ultrasound. RESULTS: We enrolled 493 patients meeting the criteria. Median age was 65 years, with 54% (n = 266) being male. Regarding outcomes, 40.5% (n = 200) were hospitalized, 27.7% (n = 137) underwent surgery, and 7.9% (n = 39) underwent bowel resection. Mortality rate during hernia-related hospital admission was 0.6% (n = 3). For hospitalized patients, there were significant differences in white blood cell count, neutrophil count and percentage, platelet count, lymphocyte count, and percentage (p < 0.05). Patients undergoing resection showed significant differences in neutrophil count, neutrophil percentage, lymphocyte count, and lymphocyte percentage (p < 0.05). Lactate levels were statistically significant in all patient groups requiring hospitalization, surgery, and resection (p < 0.05). Sensitivity and specificity of lactate test results indicated in patients undergoing bowel resection, lactate values ≥1.96 mmol/L had a specificity of 64%, sensitivity of 71%, and a negative predictive value of 96% (p < 0.05). CONCLUSION: Low lactate levels in patients presenting to the emergency department with abdominal pain caused by abdominal wall hernias have a high negative predictive value for excluding strangulation and the need for bowel resection. Therefore, we recommend the use of lactate as an additional diagnostic tool in emergency department presentations related to abdominal wall hernias.
