RESUMEN
BACKGROUND: Trans-abdominal pre-peritoneal (TAPP) hernia repair is a complex procedure that presents several challenges. Even though, due to the high prevalence of inguinal hernia, TAPP technique is increasing in frequency and robotic Abdominal Wall Surgery (rAWS) is emerging as a valuable tool in this regard. Although inguinal TAPP procedure principles have been published and simulation is needed, the availability of validated models remains scarce. METHODS: A new low-cost model was developed to simulate inguinal rTAPP repair. For validity assessment, a new TAPP-specific fidelity questionnaire and assessment scale were developed to compare the performance of novices and experts in the simulated procedure. The models used were assessed at 60 min for execution and quality score. RESULTS: Twenty-five residents and specialists from all over the country participated in this study. Execution, quality, and global performance was higher in the seniors group compared to juniors (8.91 vs 6.36, p = 0.02; 8.09 vs 5.14, p < .001; and 17 vs. 11,5, p < .001, respectively). Overall fidelity was assessed as being very high [4.41 (3.5-5.0), α = .918] as well as face [4.31 (3.0-5.0), α = .867] and content validity [4.44 (3.2-5.0), α = .803]. Participants strongly agreed that the model is adequate to be used with the DaVinci® Robot [4.52 (3.5-5.0), α = .758]. CONCLUSION: This study shows face, content, and construct validity of the model for inguinal TAPP simulation, including for robotic surgery. Therefore, the model can be a valuable tool for learning, understanding, practicing, and mastering the TAPP technique prior to participating in the operating room.

Cellular angiofibromas (CAFs) are infrequent and benign soft-tissue tumors that primarily affect the genitourinary region in both genders. The authors report the case of a 71-year-old male patient who exhibited progressively increasing swelling in both testicles, with greater prominence noted on the left side. Initial findings from physical examination and scrotal ultrasound indicated the possibility of bilateral hydrocele, so the patient was recommended surgical intervention of the left more prominent side. Intraoperatively, a left paratesticular mass was identified and subsequently excised. Histopathological analysis confirmed the diagnosis of cellular angiofibroma. Surgeons should be cognizant of this tumor type to optimize treatment strategies, as local excision demonstrates a potential to preserve the testicle and yield favorable outcomes. Although occurrences of local recurrence are extremely rare, long-term follow-up is imperative.
