Groin swellings- Introduction
 Causes of groin swellings
 Anatomy of inguinal canal
 Anatomy of femoral canal
 Embryology of testicular descend
 Algorithm to clinch the correct diagnosis
Causes of Groin swellings
 Inguinal hernia- Indirect & direct
 Femoral hernia
 Undescended testis
 Inguinal lymphadenitis
 Lipoma of spermatic cord
 Encysted hydrocele
 Saphena varix
 Femoral artery aneurysm
 Psoas abscess
 Femoral nerve neuroma
Anatomy- Inguinal canal
 Inguinal canal is about 4cm in length extending from deep
inguinal ring to the superficial inguinal ring.
 Superficial inguinal ring: is an inverted v-shaped defect in
the external oblique aponeurosis immediately superior to the
pubic tubercle.
 Deep inguinal ring: It is ½" or 1.25cm above the mid-inguinal
point-the midpoint between the symphysis pubis and anterior
superior iliac spine. It is U-shaped defect in transversalis
fascia.
Anatomy- Inguinal canal
 Anteriorly- external oblique aponeurosis and fleshy fibres of the
origin of internal oblique in its lateral 1/3rd.
 Posteriorly—Fascia transversalis along the whole length of the
canal. In the medial half there are conjoint tendon and reflected
part of the inguinal ligament.
 Superiorly—There are arched fibres of internal oblique and
transversus abdominis before they fuse to form the conjoint
tendon.
 Inferiorly—Inguinal ligament and the lacunar ligament on the
medial side (Gimbernat’s ligament).

Anatomy- Femoral canal
 Femoral Canal: It extends from the femoral ring above to the
saphenous opening (fossa ovalis) below, being the innermost
compartment of the femoral sheath.
 Length – 2cm, shape: It looks like the inverted truncated cone, the
upper end being the femoral ring
Contents of the femoral canal
 1. Fibrofatty tissue
 2. Lymph nodes and lymphatics. Lymph node situated at the ring is
known as Cloquet’s node.
Anatomy- Femoral ring
Femoral Ring: Boundary
 Anterior—Inguinal ligament
 Posterior—Iliopectineal ligament and pubis.
 Medially—Crescentic edge of the lacunar ligament
 Laterally—Fibrous septum separating the canal from the
femoral vein (Silver fascia).
 The ring is closed above by the septum crurale – a condensed
extraperitoneal tissue pierced by the lymphatic vessels.
Anatomy- Femoral canal
Embryology of testicular
Descend
 Primitive gonad in urogenital ridge turns into
testis by gene in short arm of Y chromosome.
Early testis 3 hormones
 Testosterone from Leydig cells CSL regression
 Mullerian inhibiting substance from Sertoli
cells Mullerian duct regression
 Insulin-like3 hormone shortening of
gubernaculum  relative descend of testis
8 to 15 wks gestation- Transabdominal phase
Embryology of testicular
Descend
 At 25 wks Processus vaginalis
elongates into gubernaculum
 Distal end of gubernaculum reach
scrotum between 30 to 35 Wks
 Then testis descend through PPV
 TestosteroneGFN CGRP
Migration of gubernaculum along
with testis to scrotum
28 to 35 wks gestation- Inguinoscrotal phase
