Objective: To summarize the experiences of resecting cardiac muscularis propria benign tumors though esophageal submucosal tunnel and examine the occurrence rate of complications.
Methods: A total of 17 cases of cardiac muscularis propria benign tumor as diagnosed by endoscopy and endoscopic ultrasonography underwent endoscopic submucosal tunnel dissection from January 2012 to October 2013. And the appearances of lesions and the operative complications were recorded and analyzed.
Results: All lesions were successfully resected with a mean diameter of 1.6 (0.8-3.5) cm. There was no recurrence. The mean operative duration was 43 (26-105) min. The appearances of lesions were regular (n = 5) and irregular (n = 12). There was no instance of severe bleeding or perforation. Resection of muscularis propria was performed for 3 cases. The complications included pneumoderm (n = 3) and pneumoperitoneum (n = 3). All the above cases were discharged after conservative treatment.
Conclusion: Endoscopic submucosal tunnel dissection is safe, reliable, convenient and fast for cardiac muscularis propria tumors method.
