  • Title: Results of myotomy and partial fundoplication after pneumatic dilation for achalasia.
    Author: Ferguson MK, Reeder LB, Olak J.
    Journal: Ann Thorac Surg; 1996 Aug; 62(2):327-30. PubMed ID: 8694585.
    Abstract:
    BACKGROUND: We questioned whether results of myotomy for achalasia are influenced by previous pneumatic dilation and whether surgical outcome is influenced by a dilation-related perforation necessitating urgent operation. METHODS: We performed a retrospective analysis of 60 patients who underwent transthoracic myotomy and fundoplication from 1977 to 1995. Dysphagia, heartburn, pain, and regurgitation were scored on a scale of 0 to 3 and results were classified according to combined symptom score. RESULTS: Dilation was performed before myotomy once in 15 patients, twice in 25, 3 times or more in 9, and never in 11 patients. Operation was urgent due to perforation in 6 patients (10%). There was no postoperative leak or mortality. Overall symptom score at last follow-up (57 +/- 8 months; 90% of patients) was improved compared with preoperative score (2.1 +/- 0.3 months versus 5.1 +/- 0.2 months; p < 0.0001). Outcome was unrelated to whether or not a perforation occurred (excellent/good outcomes in 100% and 88%, respectively) or to whether or not preoperative dilations had been performed (excellent/good outcomes in 90% and 89%, respectively). CONCLUSIONS: Myotomy and partial fundoplication is an effective technique for management of achalasia. Results are unaffected by the need for urgent operation for perforation and are unrelated to whether pneumatic dilation is performed preoperatively.
