Impact of slit and nonslit mesh technique on testicular perfusion and volume in the early and late postoperative period of the totally extraperitoneal preperitoneal technique in patients with inguinal hernia

Abstract 

Aims

Using slit and nonslit mesh in laparoscopic totally extraperitoneal preperitoneal (TEPP) inguinal hernia repair are well-known approaches. The aim of this prospective, randomized, clinical study was to assess testicular perfusion after these procedures.

Methods

In the study period, 40 male patients with unilateral inguinal hernia were assigned into 2 equal groups as follows: slit (S) and nonslit (NS). TEPP hernia repair was performed in all patients. In the 2 groups, testicular arterial blood flow and testis volumes were measured by Doppler ultrasonography preoperatively, on the 5th postoperative day, and 6 months postoperatively, respectively.

Results

No statistically significant difference was found between the preoperative, 5th day postoperatively, and 6-month arterial resistance index (ARI) results when comparing the S and NS groups in ultrasonographic testicular blood flow studies. There was no statistically significant difference of testicular volume between the preoperative period, the 5th postoperative day, and 6 months postoperatively in the 2 groups.

Conclusions

According to the results, no statistically significant difference was found in terms of testicular perfusion and volume between those 2 methods of TEPP repair for inguinal hernia.
