Abstract:
Objective:To evaluate high resolution esophageal manometry (HREM) in peroral endoscopic myotomy (POEM) for pediatric achalasia of cardia (AC).Methods:Data of 30 AC children who received POEM in Xi′an Children′s Hospital from January 2013 to September 2019 were reviewed. HREM was performed before and 6 months after POEM. Preoperative and postoperative lower esophageal sphincter pressure (LESP), 4-second integrated relaxation pressure (4sIRP), Eckardt scores and nutritional status were compared.Results:Children with AC aged between 4-14 years. Postoperative LESP was 5.50±1.13 mmHg (1 mmHg=0.133 kPa), which was significantly lower than that before operation (26.23±4.47 mmHg) with significant difference ( t=-24.623, P<0.001). Postoperative median 4sIRP was 5 mmHg, which was 20 mmHg lower than that before operation (25 mmHg) with significant difference ( Z=-4.786, P<0.001). Postoperative median Eckardt symptom score decreased significantly compared with that before (1 VS 8, Z=-4.796, P<0.001). Severe malnutrition of the AC children improved evidently to normal( Z=-5.166, P<0.001). Conclusion:POEM can significantly improve the characteristics of esophageal dynamics in children with AC, and HREM can be an important indicator for follow-up evaluation of POEM.
