Abstract

Objective: The aim of the present study is to show the predictive value of the preoperative resting pressure of the lower esophageal sphincter (LES) correlated with the type of fundoplication (Nissen or Dor) after Heller myotomy in our series.

 

Materials and Methods: From January 1998 to June 2010, 88 patients affected by esophageal achalasia underwent surgery at our unit. However, our study focused on a sample of 36 patients, because many data were lost or was never recorded. Among these, 14 patients underwent laparoscopic Heller myotomy plus Nissen fundoplication (group N), whereas 22 patients underwent laparoscopic Heller myotomy plus Dor fundoplication (group D). Clinical evaluation was performed using a modified DeMeester symptom scoring system consisting of the assessment of three symptoms: dysphagia, regurgitation, and heartburn. To each symptom was assigned a score from 0 to 3, depending on its severity, and the reduction in the severity of each symptom after surgery was assessed.

 

Results: The surgical treatment is considered to be effective (p<0.0001). The preoperative resting pressures of LES were compared by Student’s t-test, and it was found that patients who reported a greater improvement in the dysphagia symptom had a preoperative average pressure of LES that was significantly higher than that in other patients in both group N (p=0.03) and group D (p=0.01; p=0.003; p=0.001). The Dor treatment was shown to be more effective than the Nissen treatment (p<0.0001).

 

 

Conclusion: The preoperative resting pressure of LES is a predictive factor of surgical success both before Dor fundoplication and before Nissen fundoplication, but its predictive power is influenced by the chosen type of fundoplication.
