Pediatric anesthesia and achalasia: 10 years' experience in peroral endoscopy myotomy management.

backgroundEndoscopic treatment for achalasia (POEM) is a recently introduced technique that incorporates the concepts of natural orifice transluminal surgery. Although pediatric achalasia is rare, POEM has been episodically used in children since 2012. Despite this procedure entails many implications for airway management and mechanical ventilation, evidences about anesthesiologic management are very poor. We conducted this retrospective study to pay attention on the clinical challenge for pediatric anesthesiologists. We put special emphasis on the risk in intubation maneuvers and in ventilation settings.

resultsWe retrieved data on children 18 years old and younger who underwent POEM in a single tertiary referral endoscopic center between 2012 and 2021. Demographics, clinical history, fasting status, anesthesia induction, airway management, anesthesia maintenance, timing of anesthesia and procedure, PONV, and pain treatment and adverse events were retrieved from the original database. Thirty-one patients (3-18 years) undergoing POEM for achalasia were analyzed. In 30 of the 31 patients, rapid sequence induction was performed. All patients manifested consequences of endoscopic CO

conclusionsPOEM procedure seems to be characterized by a low-risk profile, but specials precaution must be taken. The inhalation risk is actually due to the high rate of full esophagus patients, even if the Rapid Sequence Induction was effective in preventing ab ingestis pneumonia. Mechanical ventilation may be difficult during the tunnelization step. Future prospective trials will be necessary to individuate the better choices in such a special setting.
