title: Posterior sagittal rectal myectomy for persistent rectal achalasia after the Soave procedure for Hirschsprung's disease.
abstract: For the management of persistent rectal achalasia after the Soave endorectal pull-through procedure, we have used posterior sagittal myectomy of the remaining aganglionic rectal muscular cuff, and have had satisfactory outcomes in five patients. Via a posterior sagittal skin incision, the posterior aspect of the rectal muscular cuff is reached. With the striated muscular complex retracted downward, the level of the dentate line is identified on the posterior wall of the rectum with the aid of the surgeon's finger inserted inside the anorectum. Two parallel longitudinal incisions are made on the rectal muscular cuff to create a muscular strip which is elevated and excised; the distal end of the myectomy strip is at the level of the dentate line and includes a part of the internal and sphincter muscle. During the last 4 years, we performed this procedure in 5 patients with remarkable relief of constipation, distension, and enterocolitis. The advantages of this procedure include: (1) less technical difficulty than the transanal approach, (2) avoiding colostomy, and (3) promising results.
