ABSTRACT
Background: Ilioinguinal nerve frequently injured during lower abdominal surgeries especially during inguinal hernia repair. Objective: To identify the variations of ilioinguinal nerve related to the spermatic cord. Materials and method: A multi-centric prospective cross-sectional stu nu r pt m r w s rri out t the department of anatomy at 11 Medical Colleges, in Khartoum state. All cadavers satisfied the inclusion criteria were enrolled into the study. The inguinal canal was opened by an oblique incision on the apponurosis of the external oblique muscle parallel to the inguinal ligament. Different relations of the nerve to the spermatic cord were observed. The data was collected using a predesigned questionnaire and analyzed statistically using SPSS version 21.0 for Windows. Results: The ilioinguinal nerve was identified bilaterally in 77 cadavers resulting in 154 ilioinguinal nerves. It was related to the spermatic cord in seven patterns. It was travelling superficial or superior to spermatic cord in 92 (59.7%) specimens, this relation was observed on the right and left sides in 47 (30.5%) and 45 (29.2%) respectively. In 27 (17.5%) specimens the nerve was related to the anteriolateral side of the cord. While in 11 (7.1%) specimens the nerve seen to pass lateral to the cord. In one specimen the nerve on the left side, it was incorporated into the spermatic cord (0.6%) this relation. In 19 (12.3%) specimens the nerve seen to pass deep to the cord. Conclusion: Cadaveric dissection of the nerve topography delineates variations not commonly cited in anatomical textbooks.
