Only a few studies have assessed long-term outcomes and relief of dysphagia following LHM.

B. Pant Institute of Postgraduate Medical Education and Research, New Delhi. The myotomy was performed by BDT in all patients. A fundoplication was added in selected patients. Post-operative Eckardt score &gt;3 was considered treatment failure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 100 patients underwent surgery during the study period. Of them, 66 patients underwent LHM, 27 underwent LHM with Dor fundoplication and 7 underwent LHM with Toupet fundoplication. The median length of myotomy was 7 cm. The mean operative time was 77 \u00b1 29.27 min and the mean blood loss of 28.05 \u00b1 16.06 ml. Five patients had intraoperative oesophageal perforation. The median length of hospital stay was 2 days. There was no hospital mortality. The post-operative integrated relaxation pressure (IRP) was significantly lower than the mean pre-operative IRP (9.78 vs. 24.77). Eleven patients developed treatment failure, of which ten patients presented with recurrence of dysphagia. There was no difference in symptom-free survival amongst various types of achalasia cardia (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.816).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>LHM performed by BDT has a 90% success rate.
