Q

ANATOMY OF INGUINAL CANAL (WALLS)?

A

ANTERIOR WALL
- aponeurosis of external oblique muscle

POSTERIOR WALL
- transverse fascia

SUPERIOR WALL
- arching fibres of internal oblique m. + transverse abdominis m.

INFERIOR WALL
- in rolled edge of inguinal ligament

INTERNAL RING
- round ligament / spermatic cord emerge through transverse fascia

EXTERNAL INGUINAL RING
- V-shaped opening of anterior wall immediately superior to pubic tubercle

Q

RICHTERS HERNIA

A

CONTAINS PART OF CIRCUMFERENCE OF BOWEL WALL > CAN CAUSE STRANGULATION WITHOUT OBSTRUCTION

/Users/ARUNISHA/Desktop/Richter+s+hernia.jpg

17
Q

MAYDLES HERNIA

A

CONTAINS 2 ADJACENT LOOPS OF BOWEL

> SEGMENTS BETWEEN LOOPS MAY BE STRANGULATED

18
Q

LITTRES HERNIA

A

HERNIA CONTAINS A MECKELS DIVERTICULUM

19
Q

WHAT IS MECKELS DIVERITCULUM

A

ABNORMAL POUCH OF TISSUE ON A SMALL INTESTINE

20
Q

FEMORAL VS INGUINAL HERNIA

A

UPPER MEDIAL BORDER OF FEMORAL HERNIA > ALWAYS BELOW + LATERAL TO PUBIC TUBERCLE

21
Q

WHY SHOULD YOU NEVER TRY MANUAL REPOSITIONING OF STRANGULATED UMBILICAL HERNIA?

A

MANUAL REPOSITIONING = TAXIS

> shifts strangulated bowel loop from one location to another
false positive success of taxis

22
Q

HERNIA WHICH GETS INCARCERATED OFTEN + SHOULD BE REPAIRED AS SOON AS DIAGNOSED?

A

FEMORAL HERNIA

23
Q

MOST COMMON USED HERNIA REPAIR?

A

LICHTENSTEIN REPAIR

24
Q

WHICH INTERNAL ORGAN IS FOUND IN HERNIA SAC OF INGUINAL HERNIA?

A

OMENTUM

SMALL INTESTINE

25
Q

A BULGE/ LUMP IN INGUINAL REGION AND SCORTUM APART FROM INGUINAL HERNIA COULD BE?

A

VARICOCELE
TESTICULAR TORSION
FEMORAL HERNIA
HIDRADENITIS OF INGUINAL APOCRINE GLANDS

26
Q

HOW MANY HOURS AFTER ONSET OF COMPLAINTS, CAN SURGON CONSIDER TAXIS FOR INCARCERATED INGUINAL HERNIA?

A

WITHIN 2 HOURS

27
Q

WHY IS RICHTERS HERNIA DANGEROUS?

A

RESULT > STRANGULATION IN ABSENCE OF INTESTINAL OBSTRUCTION

28
Q

WHAT IS PANTALOON HERNIA?

A

RARE PRESENTATION OF INGUINAL HERNIA

BOTH INIDRECT + DIRECT HERNIA COMPONENT

29
Q

ACQUIRED UMBILICAL HERNIA IN ADULTS RESULTS FROM?

A

INCREASED INTRA ABDOMINAL PRESSURE
