Cancer - Prostate(구연) (NP-044) 근치적 전립선 절제술을 받은 환자에서 수술 중 서혜부 탈장의 예방적 시술의 효과 : 전향적 무작위 실험 결과 부산대학교 의과대학 비뇨의학과교실 구자윤, 김경환, 박지훈, 강병진, 박시균, 이권경, 하홍구 Objective Postoperative inguinal hernia (PIH) is detected in approximately 5.0% of radical prostatectomy (laparoscopic prostatectomy (LRP), or robot-assisted laparoscopic prostatectomy (RARP) in the previous study (International Journal of Clinical Oncology (2018) 23:742–748). This study was conducted to investigate the efficacy and results of simultaneous simultaneous inguinal herniorrhaphy (IHR) during radical prostatectomy (Px). Methods This study was based on 171 patient undergone radical Px, from 2017- 2018. In the previous study, the thickness of external oblique muscle (TEOM) and the width of rectus muscle (WRM) were significant risk factors for PIH after radical Px. In 39 patients with TEOM less than or equal to 7.3mm and , WRM less than or equal to 43.8mm, we performed a concurrent IHR using Premilene mesh and then we investigated the occurrence rate of PIH, Age, BMI, preoperative PSA, operative methods, operation time, Gleason score, pTstage, and the hospitalization. Results A total of 171 patients were included, and PIH after radical Px was observed in 3 (2.3%) patients. PIH was not present in patients receiving IHR. The mean age and BMI were significantly different (p =0.001, p < 0.001 respectively) between patients undergoing only radical Px and radical Px with IHR. Operation time and the hospitalization were not significantly different. Mean follow-up was 16.2 ± 6.0 months with no recurrences. Conclusion We suggest that if TEOM less than or equal to 7.3mm and, WRM less than or equal to 43.8mm, should perform a concurrent IHR. keywords : inguinal herniorrhaphy, prostatic neoplasm, prostatectomy
