The processus vaginalis (PV) is an embryonic diverticulum of the parietal peritoneum at the deep inguinal ring. The patent processus vaginalis (PPV) is the etiology for the development of an indirect inguinal hernia, and is associated with undescended testis, scrotal hydrocele. The aim of this study was to examine the characteristics of PPV in Vietnamese patients: a total of 309 adult patients who underwent transperitoneal laparoscopic surgery (TPLS) from March 2019 to March 2020 at Hue University of Medicine and Pharmacy Hospital. When a PPV was identified, the side and the size of PPV was recorded. Statistical analysis was done using the p-Value test for strength of evidence. The incidence of PPV of 309 subjects was 22 cases (7.1%). The rate of PPV in males was 12.1% and 3.0% in females (p = 0.002). The rate on the right side was 4.5%, 1.9% on the left and 0.7% on both sides. The mean PPV size was 6.1 mm ± 4.1 mm and 3.0 mm ± 0.7 mm in males and females, respectively (p = 0.004). Of all patients (both male and female) that had PPV, 3 patients (4.7%) had a BMI ≥ 23 and 19 patients (7.3%) had a BMI <23. Knowledge of the anatomy and embryology of PV and the mechanisms of obliteration and PPV can assist clinicians and ultrasonographers in the evaluation and treatment of patients who present with asymptomatic PPV.
