Are contrast swallows necessary immediately postlaparoscopic Heller cardiomyotomy?

Laparoscopic cardiomyotomy is an effective treatment for achalasia. Intraoperative leak tests are carried out to exclude mucosal perforations, additionally some surgeon perform postoperative contrast swallows. The aim of the study was to identify whether postoperative contrast swallows were necessary in all patients who undergo laparoscopic cardiomyotomy. All patients who underwent a laparoscopic cardiomyotomy at a single center between 2004 and 2011 were identified. Median age was 55 (18 to 79), median body mass index 26 (17 to 37), and median length of stay was 1 day (1 to 4). A total of 54% of patients had previous pneumatic dilatations. One intraoperative mucosal perforation was identified and repaired. No leaks were seen on the postoperative swallow; however, 1 patient was readmitted with a contained leak, 8 days after surgery. Postoperative contrast swallow did not have any clinical impact. We suggest that they are only indicated if there is a clinical concern and that laparoscopic cardiomyotomy can be safely carried out as a day case procedure.
