Background: Hernia is a common pathology in the globe and reported more frequently, particularly, inguinal hernia. Aims: To identify the surgery of choice for the treatment of hernias by evaluating the required postoperative hospitalization time, as no other complications have been reported according to data from Mordovian Republic hospital. Material and methods: A retrospective cohort study involved 790 patients for the period 2017-2022 treated surgically for various types of hernia; inguinal hernia, umbilical hernia, spontaneously reduced strangulated post-operative ventral hernia, incarcerated post-operative ventral hernia, and hernia of the Lina Alba. For statistical analysis, used T test, one way ANOVA test, and Pearson correlation test by using Statistica program. Results: The hospitalization period after Lichtenstein surgery is statistically less than Postemsky surgery (mean 6.88 days, 7.43 days, respectively, t value -2.29593, p<0.02) and laparoscopic surgery (mean 6.88 days, 8.19072 days, respectively, t value 4,206817, p<0,000031). Whereas, Postemsky surgery has shorter post-operative hospitalization period in compare to laparoscopic surgery (mean 7.43 days, 8.19072 days, respectively, t value -2.19326, p<0.02). According to the used surgical approach, the patients post-operative hospitalization days differs (mean days: min. days; max. days, 7.50192: 0.00; 30.00). According to Postemsky (M m; 7.43262, 0.167012), according to Martynov (M m; 8.37500, 0.113440), according to Lichtenstein (M m; 6.88153, 0.146845), according to Mayo (M m; 7.51282, 0.280156), according to Bassini (M m; 8.77778, 2.379179), laparoscopically (M m; 8.19072, 0.268434), according to Sapezhko (M m; 8.25000, 1.380074), and another type of surgery (M m; 11.40000, 2.501999). Women (mean 8.525114 days) hospitalized longer than men (mean 7.065371 days), t value 5.871044, p< 0.001. A statistically significant correlation has been found between age and post-operative hospitalization time (Pearson Rank Order Correlations r=0.215561, p <0.05). Conclusions: The study shows that the Lichtenstein surgery is the surgery of choice in terms of hospitalization time after the surgery. Straight association between sex and age with postoperative hospitalization days.
