Pre- and postoperative manometric studies in diffuse esophageal spasm.

Since January, 1972, the authors have operated upon 4 patients with idiopathic diffuse exophageal spasm. Clinical details and barium studies are included. Extramucosal myotomy extending from the gastric fundus to the aortic arch was done in each case. Pre- and postoperative manometric studies were carried out in all. After operation in each patient the dysphagia and substernal pain disappeared and in 3 patients radiological patterns changed. The myotomy was associated with marked fall of contractile wave pressures in the body of esophagus. The basal pressures of the esophageal body elevated, in 2 cases fell after the myotomy; in 2 with normal preoperative pressure it remained unchanged. At the lower esophageal sphincter the resting and yield pressures remained similar to the preoperative readings but the myotomy produced a disappearance of the relaxation and contraction pressure. The authors conclude that with myotomy they cannot correct the nature of the functional disorder but, by reducing the amplitude of the waves and lowering the resting pressure if elevated, they can relieve the patient's symptoms.

[Oropharyngeal functional evaluation in patients subjected to total laryngectomy with phonatory prosthesis. Manometric and isotopic study].

Our goal in this paper is to evaluate the motor function of the oropharinx using esophageal manometry and isotopic study, in patients that underwent total laryngectomy (TL) with phonatory prosthesis (PP), and with or without cricopharyngeal myotomy (CM). 50 por 100 of the laryngectomized patients showed oropharyngeal dysphagia, more frequent and stronger in patients without CM. Voice quality was considered good or medium in 12/20. With manometry we achieve that after TL there is an intense pressure reduction of the UES, higher in patients with CM, there aren't differences for other manometrics parameters. The oropharyngeal isotopic clearance is clearly disturbed in all patients, there aren't differences due to the type of surgery, neither the degree of dysphagia nor the CM. The association of a CM to PL plus PP is a surgical procedure that improves markedly the manometric and clinic results in these patients.
