Abstract
Although esophageal perforation complicates about 5% of pneumatic dilatations performed for achalasia, little is known about associated hospital and long-term courses. In order to assess the outcome of such patients undergoing emergency surgery for repair, records of seven patients sustaining perforation during pneumatic dilatation were compared to those of five patients undergoing elective myotomy during the same period. In perforation patients, mean intervals following the procedure were 3.6 hr to administration of antibiotics and 9.6 hr to surgery. The perforation and elective myotomy groups had similar mean durations of operation (3.8 vs 3.3 hr), intensive care stays (2 vs 1 days) and hospitalization (12 vs 11 days); perforation patients had a significantly longer mean interval from surgery to oral intake (7 vs 5 days). Postdischarge long-term outcomes were alike in the groups. It is concluded that patients with perforation from pneumatic dilatation that is recognized and treated promptly have outcomes that are comparable to those of patients who undergo elective myotomy.
