00:00
What is loop colostomy
and loop ileostomy?
Yes, yeah,
yeah.
00:10
When do you
do that?
Hemi.
00:21
So, why do you want to
do a primary anastomosis
and then
defunction?
Right. Yes. That's right.
It's absolutely spot-on.
00:32
Classically, we do it
for a left hemi.
00:36
Now, if you have anastomosed
that part of the transverse colon
to the upper part
of the sigmoid here,
you don't want the patient
to start feeding from day one
and for the bowel contents
to go into the anastomotic part.
00:51
So, you defunction it
temporarily.
00:54
In theory, you can defunction it this way,
can’t you?
You can defunction
both ends like this.
01:00
But then to put it back,
it's much harder
because you have taken
the whole end back,
then you'll need a GA
to put it back.
01:07
What we do is
you do a loop colostomy that way,
where you bring
it as a loop
but you don't divide the
ends of the bowel.
01:21
You divide one end of the bowel
so that it is still in continuity
but most of the fecal
content is coming out
before it's going
into the stoma,
before it is going
to the distal part.
01:35
So, the part is still in continuity
so that when you want to
reanastomose it,
you can do it
in local anesthetic.
01:43
So, all you need to do
is pull the bowel out,
suture the top part
and put it back in.
01:49
Yeah. You can
do that, yeah.
01:51
We close, you can close
the bowel under local.
01:54
But then clearly you need to see,
that's the whole purpose.
01:57
If you have an 84-year-old lady
who can't go for another laparotomy,
So in that case, you quickly defunction it,
at least for two days, three days
to give a bit of rest to the anastomotic part
and then you close it.
02:12
So, that's the whole idea
about a loop.
02:13
I suppose the only ones I've seen
are the ones that have been out
for a couple of, say,
a month or so.
02:17
Yes.
02:17
They don't just close it.
They do actually remove a bit of the loop.
02:23
The loop, because that is more like
debriding and freshening of the bowel.
02:28
I guess they don't do that.
They're the ones I’ve seen.
02:30
Then they do it under GA.
Yeah.
02:35
But the principle is to protect
the distal anastomosis
for X amount
of days.
02:48
Anterior resection,
anterior resection,
if you have enough stem distally
in the rectum, you can.
02:53
If you have preserved
the anal sphincter,
then you can anastomose the colon
with that part of the rectum.
02:58
Yeah, yeah.
02:59
Those that
we call pouch.
03:01
The j-pouch. No, j-pouch is more
like a temporary rectum.
03:05
That's classically done
in ulcerative colitis.
03:08
That is more of
when you don't have any rectum
and the sphincter
is also compromised.
03:15
You haven't done
an AP resection.
03:17
We still got a little bit of the anal canal
but there is no sphincter.
03:20
So, the feces
just can't keep on going,
so you make a pouch
to store it temporally.
03:26
Then when it fills up,
it all falls.
03:30
Yeah. If you have a sphincter,
it is safe to anastomose it
because you have
a good sphincter.
03:36
The sphincter is tight.
03:37
It is better to
anastomosis it
so the patient has got
a normal bowel, isn't it?
Rectum, yeah, that's right.
03:52
When you do a panproctocolectomy,
you probably can anastomose
because you are taking off
the entire colon.
03:57
You are bringing up an
ileostomy here, isn’t it?
Because there's nothing
to anastomose.
04:05
Subtotal also, yeah.
It’s very tricky to anastomose.
04:08
You’ll end up with ileostomy.
04:10
So, you say it’s a condition
where you might potentially go into...
04:15
Panproctocolectomy
or a subtotal colectomy.
04:17
It changes the way
you might do a subtotal colectomy?
Again, you see,
depending on the extent of the disease.
04:24
Yeah, because panproctocolectomy
is quite aggressive.
04:26
You are pretty much taking off
the whole of the bowels.
04:29
They try subtotal first then
and they go in...
04:31
Not always
but yes.
04:33
Many times you try to conserve
as much as you can.
04:35
You see patients inevitably
end up with ileostomy
because there's nothing
to anastomose.
04:41
You imagine taking off from here
all the way there,
what are we really
going to anastomose?
If you anastomose that bit of the ileum
to that much of the rectum,
patient is going to be in
the toilet all the time.
05:09
Whoa!
He’s getting very crude now.
05:13
No, you’re right.
05:14
If you are able to preserve the sphincter,
you always try for it, isn't it?
But if you just can't,
what can you do?
Ileostomy is a very bad idea
as well.
05:25
Colostomy is okay.
05:27
Colostomy is okay in the sense
functionally, it works well.
05:30
Ileostomy is a nightmare
because it excoriates the skin.
05:34
Patient has to empty about 25 times a day,
about 10-15 times a day.
05:38
It's big, so the decision is not
taken lightly to do an ileostomy.
05:43
Colostomy is okay.
You can reverse it.
05:45
No big deal. Sometimes they
just empty once or twice.
05:48
It's okay.
05:49
Of course,
it's a big deal.
05:51
But considering the clinical picture,
it’s no big deal.
05:55
But ileostomy is
much worse.
06:00
Panprocto, yeah, procto,
yeah, yeah.
06:03
Panproctocolectomy will end up
with a stoma, ileostomy.
06:09
Here?
Sigmoid colectomy.
06:12
This one? This one, you can get away
with a straightforward left hemi.
06:17
Left hemi?
Yeah.
06:18
For any of that region?
Yeah, because your blood supply,
that's middle colic and this is left colic.
06:24
I'm so happy then.
06:25
You're so happy.
06:26
But then clearly, if this goes on 2 centimeters,
this is when we have all these MDTs.
06:31
The radiologists will come up
with their smart answers.
06:34
They'll say,“No, no, no. You need to,
you can't make, we are not sure.
06:38
It could have spread
a little bit.
06:39
Why don't we take
a bit more of the colon?”
Yeah?
So, there's no real,
absolute thing to say.
06:47
Well, if it is there,
you definitely cut it off there.
06:50
Just the same,
what is a lymphatic spread,
what is a Duke staging,
what does the CT show?
But for the purpose
of your exam,
they'll give you
very straightforward scenarios.
06:59
You always see this
right hemi, left hemi,
extended right hemi, extended left hemi,
AP colectomy.
07:06
The scenario will be 5-centimeter tumor
here, there, and here
just to get you thinking and to see
whether you have understood the basic concepts.
07:15
They will never give you something
which is ambiguous.
07:18
As you very well know in the exam
that when you do your MCQ paper,
there's an examiner
who is also doing the paper, right?
Not for every exam,
more like a pilot.
07:30
If, say, 10 people in this room
get a particular question wrong,
all 10 of you
get it wrong,
they will eliminate that
question from the marking.
07:40
So, if they give you something
ambiguous there,
there's no
right answer.
07:45
Colorectal, so they will
come and say no.
07:47
Why not? Why can’t you do that?
Then that is debatable.
They won't use that question.
07:53
So, even if you get an ambiguous question,
they won't mark it.
07:55
So, usually
in the exam,
approximately two to three
questions are taken off
after you guys have written it
because they say this is too dodgy
because the paper
will be returned by someone.
08:07
When it comes to marking
the final assessment,
the guy who is looking at it…
Imagine it's
an orthopedic surgeon.
08:12
We discussed about the garden three
classification, undisplaced, displaced.
08:18
He says, “Well, we can do it this way.
How do you know this is such?”
He might have been trained in that hospital.
How is it wrong?
Then they'll say,
"Fine. Take it off."
Usually, those ambiguous,
don’t worry it’s ambiguous.
08:35
Right. We’re on track for this.
Any question on this?
Did you get a fair idea
of what you need to know in the exam?
I am going on
to the inguinal region.
08:48
We are not going
to expose him.
