Background: The utilization of laparoscopic and open inguinal hernia repair in China remains unclear. We aim to investigate the rates of laparoscopic and open inguinal hernia repairs and its associated factors at a large hernia center. Methods: Data were obtained from the front sheet of medical records of Beijing Chaoyang hospital. Adult inguinal hernia inpatients who underwent hernia repairs between 2013 and 2020 were included. We calculated the overall rates of laparoscopic and open inguinal hernia repairs and compared the rate of laparoscopic repairs between different sex, age groups, types, and sides of inguinal hernias. Multivariable logistic regression was used to examine factors associated with the rate of laparoscopic repairs. Results: 14,481 inpatients with inguinal hernia were included. 91.78% were male, 75.43% were more than 50 years, 75.20% were unilateral inguinal hernia, and 64.57% were indirect inguinal hernia. Overall, 49.47% underwent laparoscopic repairs and 50.53% underwent open repairs. Women had lower rate of laparoscopic repair than men, especially in those with unilateral hernias. Bilateral and direct inguinal hernia had higher rates of laparoscopic repair than unilateral and indirect inguinal hernia. Multivariable logistic regression showed that inpatients who were women, > 70 years, pantaloon inguinal hernia, with obstruction, and more comorbidities were less likely to have laparoscopic repairs. Conclusion: Around 50% of inguinal hernia patients at a large hernia center underwent laparoscopic repairs, which was more commonly performed in male, young, bilateral inguinal hernia, and inpatients without comorbidities. More efforts were needed to increase the safe and effective laparoscopic utilization among female patients with inguinal hernias. [ABSTRACT FROM AUTHOR]

Purpose: The myopectineal orifice (MPO) is a weak area at lower part of the anterior abdominal wall that directly determines the mesh size required in inguinal hernia repair. However, MPO data have mainly been acquired from measurements of cadavers or anesthetized patients. Furthermore, there are very few reports on the measurement of the MPO in Chinese patients. The present study aimed to use three-dimensional visualization technology to measure the MPO in live non-anesthetized Chinese patients, and to use this information to indicate the appropriate mesh size required for inguinal hernia repair. Methods: In this study, we used the parameters of the MPO and the pelvis that were measured in 40 patients with peripheral arterial disease of the lower limb arteries (80 inguinal regions) using Medraw software (Image Medraw Technology Co., Ltd., China). Results: The result showed that the average width and height of the MPO were 5.71 ± 0.99 cm and 4.96 ± 0.69 cm, respectively (5.22 ± 0.77 cm and 5.13 ± 0.63 cm in males, and 6.20 ± 0.95 cm and 4.80 ± 0.71 cm in females). The average projected area of the MPO was 16.06 ± 4.37 cm2 on the left, and 15.61 ± 4.10 cm2 on the right (P > 0.05). Conclusion: Three-dimensional visualization was used to measure the area, width, and height of the MPO in living non-anesthetized Chinese patients. MPO area was correlated with age, but not with pelvic parameters. [ABSTRACT FROM AUTHOR]
