Long-term outcome of esophageal myotomy for achalasia

Figure 1 Clinical scores before and at various intervals after Heller’s myotomy. Data were expressed as mean ± SD. ^aP < 0.001 vs before surgery.

Figure 2 Lower esophageal sphincter (LES) pressure before and at various times after Heller’s myotomy. Data were ex-pressed as mean ± SD. ^aP < 0.001 vs before surgery.

Figure 3 Esophageal manometric tracings obtained from a 29-y female patient with achalasia before and after Heller’s myotomy. A, Preoperative manometry showed simultaneous contractions of the esophagus, suggestive of no pulsive peristalsis. B, Esoph-ageal manometry revealed peristaltic contractions seven years after Heller’s myotomy.
