Reoperations for esophageal achalasia

Purpose

To define the factors predisposing to recurrence and evaluate the results of reoperations for achalasia.

Methods

We reviewed the medical records of ten patients (4 men and 6 women; mean age, 51.5?±?11.0?years), who underwent reoperations for achalasia between August 1994 and August 2010.

Results

The primary surgical procedures were Heller–Dor (HD) cardioplasty in nine patients and Heller myotomy in one patient. The factors contributing to failure of the primary operation included inadequate myotomy (n?=?2), recurrent adhesion after myotomy (n?=?2), reflux esophagitis (n?=?2), difficulty in passage caused by tortuosity of the esophagus (n?=?2), difficulty in passage through the thoracic esophagus (n?=?1), and severe chest pain (n?=?1). The reoperations included repeated HD procedures (n?=?4), repair of an esophageal hiatal hernia (n?=?2), thoracic esophageal myotomy (n?=?2), straightening of the lower esophagus with gastropexy (n?=?1), and subtotal esophagectomy (n?=?1). The success rate of the reoperations for resolving symptoms was 90?% (9 patients).

Conclusion

Selecting surgical procedures based on the causes and conditions of recurrence led to symptomatic improvement and acceptable outcomes.
