Abstract Introduction: Surgical site infection (SSI) is one of the main complications in surgery for generalized peritonitis due to acute appendicitis (GPAA). The best option between primary (PC) and delayed (CD) laparotomy closure is still a matter of controversy. The objective of this study was to determine the association between the type of closure and the development of SSI in patients with GPAA. Material and method: Randomized Clinical trial. Patients with GPAA were recruited without exclusion of sex or age, and underwent surgery in the Surgery Service of Hospital Obrero No. 1 (La Paz, Bolivia) between July 2019 and November 2021; they were randomly assigned to PC and DC; with a minimum follow-up of 30 days postoperatively. Descriptive statistics were applied (calculation of percentages, measures of central tendency, and dispersion); and subsequently, analytical statistics were applied to study the association between variables (Fisher's exact test for categorical variables and Student's T test for continuous variables). AR, RR, OR, NNTand their respective 95% CI were determined. Results: 100 patients were included, divided into 59 with PC and 41 with CD, with average age, weight, height, and BMI of 43±13.1 years, 71 ±8.5 kilograms, 1.61 ±0.8 meters and 27.6±3.2 respectively. The SSI was 29.8% and 4.7% in the PC and DC groups respectively. The incidence of SSI for DC was 0.05 (5%) and 0.30 (30%) for PC. For seromas, the AR for DC is 0.27 and for PC 0.55. The Number Needed to Treat (NNT) was 3.97 (95% CI: 2.75-5.19). There was no mortality. Conclusion: DC is associated with a lower incidence of SSI
