Background:
Extramucosal myotomy of the lower esophagus and cardia, combined with anterior fundoplication, is, in our opinion, the procedure of choice to treat stage I-III esophageal achalasia.
Methods:
After a successful experience with open surgery in over 280 patients, from January 1992 through February 1997, 61 patients underwent laparoscopic Heller-Dor for stage I-III achalasia. Conversion to laparotomy was done in three cases. All procedures were performed under intraoperative endoscopic control. Intraoperative complications were seven mucosal tears, which were sutured laparoscopically in five cases. The sole postoperative complication was bleeding from an acute gastric ulcer (conservative treatment).
Results:
Follow-up consisted of clinical and radiographic study 1 month after surgery, and endoscopy and manometry within 1 year. After a mean follow-up (F.U.) of 21 months (1-62), clinical results range from excellent to good in 98.2%. One patient (1.7%) complaining of recurrent dysphagia improved after endoscopic dilation. Esophageal diameter reduced from 52 to 27 mm. LES pressure reduced from 30.3 +/- 12.4 to 10.7 +/- 3.5 mmHg (basal) and from 14. 8 +/- 9.3 to 2.9 +/- 2.1 mmHg (residual).
Conclusions:
Laparoscopic Heller-Dor operation is feasible, safe, and effective. Special care should be taken in patients with previous endoscopic dilations.
