ACHALASIA AND PERORAL ENDOSCOPIC MYOTOMY POEM

patient experienced an aspiration after a standard induction. Procedure was cut short and
recapped on a later moment when the patient was successfully intubated after a rapid
sequence induction with cricoid pressure. Anaesthesia was maintained with sevoflurane,
desflurane or propofol. In contrast to our own experiences, the authors stated that POEM is
relatively painless requiring only small amounts of opioids.

the use of a special tube with the
possibility of suction of irrigation fluid under the glottis and above the cuff (TaperGuard
Evac, Covidien). The authors intubated 35 patients who underwent POEM with this special
tube and experienced no aspiration.

However, this also can be achieved by using the
suction canal of the endoscope during withdrawal from the oesophagus.
Own experiences
Nearly 160 POEM procedures have been performed in the AMC. All patients scheduled for
POEM have to follow a strict liquid diet for three days prior to the procedure. Twenty-four
hours before procedure they may only take clear liquid and 8 hours before nothing more by
mouth. During time out, patients will be asked about their own feeling of stasis of food in the
oesophagus. All patients are intubated in a RSI setting without cricoid pressure. In doubt of
stasis in the oesophagus, awake fiberoptic intubation with remaining airway reflexes is the
option of choice. Until now, we did not have any aspiration during intubation. Alternatively,
it is an option to start with an oesophago-gastroscopy under light sedation to remove
remaining food in the oesophagus and stomach. We have not yet applied thismethod. There
is no specific protocol for medication during induction or for maintenance of anaesthesia.
Our data show that POEM is a painful procedure. Therefore, all patients receive multimodal
intravenous pain therapy with acetaminophen, non-steroidal anti-inflammatory drugs
(NSAIDs) or alternatively metamizol, esketamine, and an opioid combined with co-
analgesics like clonidine and dexamethasone.
The first hours after procedure, patients stay in the recovery room and are titrated with
morphine as necessary. Usually, intravenous treatment with paracetamol, NSAID, or
metamizol is sufficient. The first 24 hours patients are not allowed to eat and drink, so
they are treated with a crystalloid and glucose infusion for this time. After the barium
swallow on the first postprocedural day, patients start with clear liquid followed by liquid
diet that is slowly extended. Patients are treated with omeprazole for two weeks after the
procedure. For most patients pain medication is still necessary in the first two to three days
postoperatively.
