Objective: Determine the effectiveness of lavage versus peritoneal drying on the formation of residual abscess due to secondary peritonitis in patients at the José Soto Cadenillas Hospital during the period September 2016 and September 2022. Material and Methods: The present study was an observational, retrospective cohort analytical study. 89 patients were included, who were divided according to the exposure factor, with 52 patients undergoing peritoneal lavage (exposed group) and 37 patients undergoing peritoneal drying (non-exposed). The incidence of residual intra-abdominal abscess was evaluated in the exposed and non-exposed group. Additionally, the association of the residual abscess with the intervening variables was determined. The Z test for comparison of proportions and Pearson's Chi square test were used. The strength of association was determined using the relative risk (RR). Results: The average age of patients with secondary peritonitis was 44 years, 47.2% were female and 52.8% were male, the median operative time was 45min and the median hospital stay was 8 days. According to the Risk Ratio (RR) test, multivariate analysis determined that patients who underwent peritoneal lavage showed a 1.05 times greater risk of developing residual abscess compared to those patients who underwent peritoneal drying, this association being non-significant ( RRa = 1.05; 95% CI = 0.16 – 2.00; p = 0.98); However, an operative time greater than or equal to 45 minutes appeared to be a significant risk factor for residual abscess in patients with secondary peritonitis (aRR = 3.95; 95% CI = 1.16 – 13.46; p = 0.03). Conclusion: Peritoneal lavage is not more effective than peritoneal drying on residual abscess formation in patients with secondary peritonitis
