Comparison between modifled rives procedure and bilayer mesh repair in management of large inguinoscrotal hernia and their effect on testicular volume and perfusion

Abstract EN

Aim : to compare two different techniques in management of inguinoscrotal hernia with destroyed transversal is fascia of myopectineal orifice (Nisus type III B and IV B and D), modified Rives procedure (MRP) and bilayer mesh repair (BMR) as regard : surgical problems, operative time, postoperative complications, hospital stay, effect on testicular volume (TV) and perfusion (TP) and recurrence rate.

Patients and methods : Patients were divided into 2 comparable groups as regard age, BMI and type of hernia : I: 29 patients underwent MRP, II: 30 patients underwent BMR, preperitoneal mesh inserted through internal ring and only patch.

US and CDUS were done to measure TV and peak systolic and end diastolic velocities and accordingly resistive index (RI) measured as indicator of TP.

TP on hernia side was compared with healthy side preoperatively and with same side after one year.

TV was measured postoperatively after One year.

Results : MRP was demanding and difficult especially in patients with BMI >30 and time consuming than BMR (111.24 ± 16.42 / 87.8 ± 15.96 min , P < 0.001).

BMR had less hospital stay (1.5 ± 0.68 / 1.96 ± 0.74 days, P = 0.016) but insignificant low postoperative morbidity than MRP.

No recurrence in both groups after 2.42 ± 1.007 and 2.48 ± 0.95 y respectively.

TP was impaired on hernia side preoperatively in both groups compared with healthy side (RI: 0.68 ± 0.05 / 0.08 ± 0.62, P = 0.0025 and 0.69 ± 0.04 / 0.62 ± 0.05, P< 0.001 respectively) and improved postoperatively (0.61 ± 0.007, P < 0.001 and 0.62 ± 0.07, P < 0.001 respectively).

TV was insignificantly affected (18.62 ± 2.93 / 17.56 ± 2.39 cm3, P= 0.762 and 18.38 ± 2.641 / 16.57 ± 2.51 cm3, P = 0.158 respectively).

On conclusion, BMR of Nyhus type III B and IV B and D is easier and less time consuming than MRP.

Both techniques are safe on testicles with improvement of TP postoperatively and economic.
