Abstract
Introduction: Identification of the exact position of the deep inguinal ring is important in classifying inguinal hernias. This information is often used in evaluating short cases in undergraduate as well as postgraduate examinations in Surgery. Methods: Consenting patients undergoing routine inguinal herniotomy and mesh repair in a Surgical Unit of the Teaching Hospital Karapitiya were included in the study. The length between the anterior superior iliac spine (ASIS) and the pubic tubercle (PT) was measured using a sterilized metal ruler. Results: Twenty five patients participated in this study. Fifteen had right inguinal hernia and others had left inguinal hernia. The mean distance from the PT to theASIS in those with left inguinal hernia (LIH) was 6.61cm. (SD=0.34 cm). The mean distance from the left PT to the actual position of the deep inguinal ring was 3.05 (0.14) cm. In patients who had right inguinal hernia the mean distance from the PT to the right ASIS was 6.65 (0.32) cm. The mean distance from the right PTto the actual position of the deep inguinal ring was 3.07 (0.15) cm. Conclusion: The exact position of the deep inguinal ring is medial to the mid-point of the inguinal ligament. Our data reveal that it is not lying in the mid-point of the inguinal ligament.

Highlights
Identification of the exact position of the deep inguinal ring is important in classifying inguinal hernias
The method of identifying the position of deep inguinal ring is to take the midpoint between anterior superior iliac spine (ASIS) and pubic tubercle (PT) (1) i.e., the midpoint of inguinal ligament
The superficial fascia was incised to expose the external oblique aponeurosis. This was followed by a short split with the knife in the line of the fibers of the external oblique aponeurosis over the inguinal canal
Summary
Identification of the exact position of the deep inguinal ring is important in classifying inguinal hernias. This information is often used in evaluating short cases in undergraduate as well as postgraduate examinations in Surgery. Identification of the exact position of the deep inguinal ring (DIR) is important in performing various clinical procedures and in diagnosing certain hernias. The method of identifying the position of deep inguinal ring is to take the midpoint between anterior superior iliac spine (ASIS) and pubic tubercle (PT) (1) i.e., the midpoint of inguinal ligament. We planned a study to assess the actual position of deep inguinal ring among Sri Lankan subjects.
