  • Title: [Evaluation of the functional modifications of the lower esophageal sphincter after use of the Angelchik prosthesis].

    Abstract:
    The manometric recording of Lower Esophageal Sphincter (LES) has been made in 8 patients who have undergone surgical apposition of Angelchik prosthesis for hiatal hernia. The patients underwent an esophageal manometric study in the preoperative period, one month and one year after the intervention. In the preoperative patients, the mean LES pressure was 10,3 +/- 0,5 mmHg and there was sphincterial incoordination to peristaltic waves after swallow. In one month postoperative patients the LESP was 20,1 +/- 1,0 mmHg (p less than 0,001), and one year after the LESP was 17,0 +/- 0,3 (p less than 0,001) with an ameliorated coordination of the LES activity in response to swallow. Therefore, during postoperative manometric controls the Authors identified a high pressure subdiaphragmatic zone unmodified by deglutitory acts which was not present in the preoperative investigation. Probably the presence of this zone would been explained as a consequence of mechanical action of the prosthesis and the postsurgical fibrino-reaction around the prosthesis. The Authors discussed the results obtained and their importance to Angelchik prosthesis employment for surgical correction of hiatal hernia.
