Therapeutic effects of a laparoscopic Heller myotomy and Dor fundoplication on the chest pain associated with achalasia.
OBJECTIVE
The therapeutic effects of a laparoscopic Heller myotomy and Dor fundoplication (LHD) on the chest pain associated with achalasia were investigated.


METHODS
Sixty-six patients who were diagnosed to have achalasia underwent LHD. The degree of dilatation was assessed based on the maximum horizontal diameter of the esophagus (Grades I-III). The type of dilatation was assessed based on the shape of the distal esophagus, namely, spindle type (Sp), flask type (Fk), and sigmoid type (Sig). The degree of improvement was classified into three grades as follows: A (complete disappearance), B (partial response), and C (unchanged).


RESULTS
Chest pain improved (A or B) in 22 patients (92%). The statistical results revealed that the improvement of postoperative A or B was significantly better in patients with Sp than in those with Fk or Sig (P = 0.0213). In addition, the results revealed that the improvement of postoperative A or B was significantly better in patients with grade I and grade II than in those with grade III (P = 0.004).


CONCLUSIONS
LHD is an effective therapeutic technique for the treatment of chest pain associated with achalasia. These results suggest that both the morphological type and esophageal dilatation are useful predictors for the improvement of chest pain after surgical therapy.
