Dont know about actual figures but they told me the same thing here in

England and its a bit of an unknown as they dont know how strong your e is

and its the skill of the surgeon.

1 in 5, or 20%, seems high unless this is your personal risk and not a

general risk. Are you talking about dilatation after myotomy?

See:

Management of esophageal perforation after pneumatic dilation for achalasia

http://www.ncbi.nlm.nih.gov/pubmed/11058860

" Over a 20-year period, 445 dilations for achalasia were performed in

371 patients. There were 10 esophageal perforations. Nine patients were

referred for surgery and were successfully managed with a transabdominal

repair. "

Incidence, clinical management and outcomes of esophageal perforations

after endoscopic dilatation.

http://www.ncbi.nlm.nih.gov/pubmed/18027320

" RESULTS: 248 patients (148 male, 100 female, mean age 58 years, range

14-87 years) underwent 365 esophageal dilatations: 74 pneumatic balloon

dilatations for achalasia, 79 balloon dilatations for other reasons such

as tumors, peptic stenosis, or post-radiotherapy stenosis and 212

dilatations with Savary bougies. The overall incidence of perforation

based on the number of procedures was 2.2% (8 perforations/365

procedures) and 3.2% (8/248 patients) based on the number of patients.

The perforation rate was 1.9% for bougie dilatation, 0% for balloon

dilatation and 5-4% for pneumatic balloon dilatation for achalasia. Five

patients were treated surgically and 3 patients were managed

conservatively. The mean hospital stay was 14 days (7-33 days). One

patient in whom the perforation was recognized 16 days after the

dilatation died. "

They say the risk goes up after previous treatments, dilatation or

myotomy, so your risk is probably higher than those studies imply. Maybe

I can find something about that kind of risk later.

Thanks for the info!

Yes, it is a dilatation after myotomy. I had my myotomy with dor fundo almost 5

years ago

I don't understand why there is a need to get dilation after having had the

surgery. I thought surgery was supposed to be the " permanent " fix. If the muscle

is cut during the surgery how does it end up getting tight again?

I am not having much luck finding the risk of perforation due to

dilatation after a myotomy. I have found some about repeated

dilatations. There are some studies that say that most perforation

happen on the first dilatation. Kind of counter intuitive. Here are two

studies that make that statement and there are others:

Risk factors for immediate complications after progressive pneumatic

dilation for achalasia.

http://www.ncbi.nlm.nih.gov/pubmed/10235189

" Five hundred four dilations were performed in 237 consecutive

achalasic patients... Perforations occurred in 6 of 7 patients during

the first dilation. "

Risk factors of oesophageal perforation during pneumatic dilatation for

achalasia.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1383221/

" ... 270 pneumatic dilatations were performed in 218 patients. ... Eight

oesophageal perforations occurred (3%). ... All perforations occurred

during the first dilatation. "

In the first study over half of the dilatation were on patients that had

already had a dilatation before. In the second study only a fifth of the

dilatation are repeat. If the risk was much higher for repeat dilatation

those results would be hard to get by chance. Even if the risk stays the

same it would be a bit of odd luck to get those results. This does seem

to imply that the risk actually goes down for repeat dilatations. Which

is even more amazing when you consider that often a larger dilator is

used on the second dilatation.

Perhaps it is the same after myotomy. If so, and I do say if, then the

first one is your riskiest. I am sure we have heard from a number of

members to this group that have expressed their doctors concerns for

doing dilatations after myotomy, but perhaps those doctors are just

giving the intuitive belief when the studies are actually counter

intuitive. I did find a small study that found repeat dilatation to be

more risky but it was a very small study and much more likely to be

chance. There may be other contrary studies but these two seem to be

what are cited by others.

Here is one study that addresses the dilatation after myotomy.

Pneumatic dilation for the treatment of achalasia in untreated patients

and patients with failed Heller myotomy.

http://www.ncbi.nlm.nih.gov/pubmed/15492600

" A total of 139 PDs performed (117 untreated cases, 22 failed HM): 2

perforations in untreated cases and none in failed HM group...

CONCLUSIONS: PD perforation risk is not higher after HM. "

Again, that is a small study as far as the HM (Heller Myotomy) patients

go and the HM patients only had one dilatation after the myotomy. It may

not mean much, but it too gets cited.

Scar tissue can also result from acid reflux. Scar tissue tends to

 Some of us have learned the hard way that there is no " permanent fix " because

there is nothing permanent about our bodies. Believe me, back in 1991 I thought

I had the " permanent fix " also.  I'm sure Notan can handle the technical aspect

of your question as to how it the LES ends up getting tight again. But, being

less knowledgeable, I can suggest a couple of reasons.

The muscle can heal and get tight again.

Perhaps not enough muscle was cut.

Perhaps the wrap was made too tight.

Perhaps the esophagus has gotten either, twisted, tortured, grossly dialated or

has sagged below the level of the stomach.  All of these things alone or in

combination can lead to the symptom of the muscle feeling too tight again.

After we have the surgery and have experienced the initial euphoria of being

able to eat relatively normally again, we must be mindful that we now have a

useless " pipe " connecting our the back of our throat to the entrance to our

stomach which must be treated with " respect. "   While some of the degeneration

is beyond our control, nevertheless there is much we can do to improve our

chances that this " pipe " won't need replacement in the future.

Also, scar tissue can build up from the first Myotomy. I had the first surgery

in 1974 and numerous dilations until my second Myotomy in 2008. By 2008, the

scar tissue had built up & my esophagus was an “L†shape (maybe what you

have described as “sagged below the stomachâ€).

Thanks Jan,

The build up from scar tissue is a good point.  There are many factors

contributing to the myotomy being less than a " permanent fix " and its very

important that patients having this surgery realize that going in.  Clearly, 18

years ago I did not. While it maybe the best " solution " we have now, over time

the " fix " can get " broken " through nobody's fault.  We should all have a " game

plan " for after the surgery, such as living a life style which gives us the

maximum amount of " mileage " out of our non-functioning esophagus, plus checkups

at resonable intervals to make sure that nothing is slowly happening that will

someday require another myotomy or esophagectomy.

If your physician says he personally has a 20% perforation rate, I would RUN

AWAY as fast as possible.

I wouldn't let anyone touch me if they had a perf rate over 4%, and most

experienced specialists should be even lower than that, IMO.

It wasn't the perferator, I mean the dialator that said that. I have to go to

UCSF 5 hours aways for these so when I changed medical practices I checked with

their E expert to see if he could do this locally and he gave me that number. I

forgot what the actual doc said, maybe I'll call and ask.

The new doc thinks my wrap is too tight and thinks I should go back and get

another myotompty but open this time. He is agasint lap myotomys, thinks it too

dark and tight in there to do a good job without laying you open. Luckily, he

doesn't do these he refers them all to UCSF

Thanks

what is the best way to take care of and get the most milage out of our

non-functioning E's? I want to try and take care as much as as possible to avoid

letting it get stretched out requiring a need for removal of it later on. I'm 32

and (hopefully) have many years ahead of me. I've been presenting with symptoms

for 8 months now and am at the point now where i need to decide if I should get

a dilation or myotomy. What other things can I do to take care of me E? Not try

and push it too hard? Sometimes it hurts down by the LES when I'm having a

eating bad day. Good days are when I can feel food going to my stomach (albeit

still very slowly). I try not to rush eating. I've always been a slow eating but

now I'm SUPER slow. I tend to avoid going out to eat or if I do, I'll only get

something very small cause it will take me that long to eat as it does someone

else an entire meal.
