This is to test your pathological background while you
manage a surgical problem
Usually, a surgically removed specimen containing
a pathological lesion is displayed
 You need to

 Identifying the organ: see all around and look evidences
of surgery and read all the questions in the script- you will
find the clues
 Take your time and observe the morphology
 Describe methodically: organ> nature of lesion> involved
area> characteristics of lesion> surrounding tissue
Example:

This is to test your counseling skills in surgical
practice
Counseling takes a vital role in surgical
managements
You need to
 Read the scenario and tasks several times
 Organize the core issues in your mind
 Write down the points you want to convey
 Have natural voice, maintain etiquette all along
 Use a single language, avoid medical terms
Scenario
 A 35year old lady, a college teacher and mother
of one child, presented with a small lump in her
right breast in upper and outer quadrant . It
measured 2cm in diameter, appeared mobile,
brought no change in nipple and there were no
palpable nodes in axilla. FNAC of the lump
reported ‘duct cell carcinoma’. You, being the
treating surgeon, have to convey the
information to the patient in your hospital
chamber in order to involve her in the treatment
planning.

Verbal communication: Interactive
This is to test your interactive ability in professional
conversations
 It occurs between the examinee and a senior
surgeon (interviewer) based on a scenario and set
questions, but supplementary comes up as
conversation goes on
 You need to

 Listen to the question very carefully: catch the reason
 Answer precisely, never say everything
 Give a chance to ask the next question that you know
 Never say anything but evidence based information
 Skip quickly if something is not known to you
Verbal communication: Interactive
Example page-1
Scenario
A one year old girl was brought to the hospital by parents as
she had facial defect since birth.
Instruction to Interviewer

management of patient’s cleft lip and palate. You are
allowed to ask supplementary clarifying questions in
response to the answers as and when required.
1. What is the diagnosis?
2. What is the developmental basis of this abnormality?
3. What are the present problems of this baby?
4. What would be your advice to the parents regarding
feeding and airway?
5. What complications will arise if reconstruction is not
done?

This is for testing your surgical skills that are
essentially the standard or recommended
techniques you follow while performing a
surgical procedure
You need to
 Read the scenario and the tasks several times
 Go by the written instructions at the station
 Stick to standards of surgical skills, not you style
 Go slow, but steady; ask for assistance
Surgical skills Example page-1
Procedure
You will have to perform a basic surgical procedure on a stitching
board using available instruments and materials.
Task:
1. Close the incision made on the board by a ‘continuous
interlocking’ suture considering it as planned skin incision
2. Put surgeons’ knot at the beginning
3. Put Aberdeen knot at the end
Instructions:
1. Introduce yourself with your Code number
2. You don’t need to put on gloves
3. Use 2/0 silk on curved cutting needle
4. Ask for assistance
Allotted time: 5 minutes
Check list
Starting knot
1.
Passes the needle at the end of the incision
2.
Makes first throw with double twist
3.
Makes second throw with single twist to make a reef/squire knot
Continuation of suture
1.
Enters the needle into the skin vertically- passes the needle along its long axis- exits at an
identical point on opposite side
2.
Keeps distance of entry/exit points from incision margins equal to its depth
3.
Suture interlocks on side of the first knot
4.
Keeps distance between the stitches equal and half that of depth of the incision wound
5.
Maintains adequate tension approximating the wound margin
End knot-Aberdeen
1.
Stops the continuous suture at the other end by the final pass close to the just previous one and
forms a loop without tightening
2.
Passes several Aberdeen knots and adequately tightens by bedding those down
3.
Makes final pass of thread through loop to end the knot and cuts it
General considerations
1.
Holds needle at the tip of needle holder 2/3 away from tip
2.
Holds the wound margin with tooth dissecting forceps or skin hook while passing the needle
3.
Holds the needle holder and forceps properly
4.
Never touches the needle by hand
