RESUMEN
The aim of this study was to determine the feasibility of prosthetic mesh repair according to the degree of bowel necrosis in the emergency management of acutely strangulated groin hernias. Emergency prosthetic mesh repair versus primary suture repair was randomly performed in 208 consecutive strangulated groin hernia patients with bowel necrosis between January 2005 and August 2016. The degree of bowel necrosis of each patient was determined according to a modified three-grade classification system. Patient characteristics sorted by repair method were analyzed by using Pearson's chi-squared tests. Correlations between mortality and wound-related morbidity with bowel necrosis grade and repair method were analyzed. There was no difference in gender, age, body mass index, comorbid diseases, hernia type (left or right, primary or recurrent), necrosis grade, and mortality between the mesh repair and suture repair groups (all P > 0.05). However, with regard to wound-related morbidity, there was significant difference between the two groups (P < 0.05). Mortality and wound-related morbidity showed significant relationship with necrosis grade, especially with regard to postoperative wound infection (P < 0.001). The wound infection rate with mesh repair was significantly higher than that with primary suture in Grade II and III necrosis patients (P < 0.05), but there was no difference in Grade I patients (P > 0.05). The use of prosthetic mesh in the emergency repair of acutely strangulated groin hernias seems to be as safe as suture-only repair in patients with noninfected strangulated bowel (Grade I necrosis). The use of prosthetic mesh repair is a rational choice made based on the degree of bowel necrosis in the emergency management of acutely strangulated hernias.

The objective of this study was to determine a classification system for BN in incarcerated groin hernia patients and to explore the possible relationship between BN staging and patient outcomes. Incarcerated groin hernia patients treated with emergency bowel resection from January 2008 to December 2013 were screened for inclusion in a prospective study. A novel three-stage classification system was proposed for BN (BN stages I-III) and correlations between adverse events (AEs) and mortality with BN stage were determined. A total of 108 patients were included, with 71, 26, and 11 patients in BN stages I, II, and III, respectively. AEs, which included wound and intra-abdominal infections and other systemic complications, increased with higher BN stage (all P < 0.05). Mortality increased with BN stage, with 2.8%, 7.7%, and 27.3% at BN stages I, II, and III, respectively (P < 0.05). The proposed BN staging system can objectively reflect the degree of bowel damage and its corresponding adverse outcomes.
