Clinical value of submucosal tunneling endoscopic resection in submucosal tumors of the esophagus and cardia derived from the muscularis propria

BACKGROUND

Submucosal tunneling endoscopic resection (STER) is a new method for treating submucosal tumor in recent years, which is minimally invasive, with few complications and rapid recovery for patients. This study analyzed the data of patients who underwent this surgery at our hospital and explored the feasibility, effectiveness, and safety of this procedure for submucosal tumors.

AIM

To evaluate the efficacy, safety, and clinical value of STER in the treatment of submucosal tumors of the esophagus and cardia derived from the muscularis propria.

METHODS

Sixty patients who underwent STER for submucosal tumors of the esophagus and cardia derived from the muscularis propria were included. The results of endoscopic ultrasonography, procedure success rate, postoperative complications, postoperative pathological results, and postoperative follow-up data were recorded and analyzed statistically.

RESULTS

All of the cases completed the STER, with a success rate of 100%. The diameter of submucosal tumors was 1-5 cm. The operation took 31 to 123 min, and the average operation time was 81.73 min ± 23.23 min. The length of submucosal tunnel was 4-8 cm, with an average value of 5.88 cm ± 1.17 cm. Postoperative pathology confirmed that there were 42 cases of leiomyoma and 18 cases of stromal tumor. Two patients developed subcutaneous emphysema and right-side pneumothorax post operation, who were cured with conservative treatment. All cases were followed for 3 mo without any residual or recurrence of the lesion and no complications such as esophageal stenosis.

CONCLUSION

STER is effective in the treatment of submucosal tumors of the esophagus and cardia derived from the muscularis propria, with few complications and high safety.
