Abstract:Objective To investigate the feasibility, safety, effectiveness and economy of ultrasound microprobe combined with endoscopic multi-band mucosectomy (EMBM) in the treatment of esophageal submucosal tumors (SMTs).Method A retrospective analysis of 103 patients from January 2013 to June 2019. Ultrasound microprobes confirmed that the esophageal submucosal tumors originated in the mucosa and submucosa with a diameter of less than 2 cm was admitted to the hospital for EMBM treatment. Collect and analyze the clinical data and surgical data of the patients, observe and record the operation time, surgical complications, the overall resection rate, and follow-up after the recurrence or metastasis, summarize the therapeutic efficacy of EMBM.Results Endoscopic treatment was successfully performed in 103 patients, 98 patients (95.15%) were successfully treated with EMBM, 3 patients (2.91%) underwent ligation without electrotomy, and 2 patients (1.94%) were switched to Endoscopic submucosal tunnel tumor resection (STER). A total of 95 cases (92.23%) achieved monolithic resection. The average operation time was (30.2 ± 10.7) min. The bleeding of 2 cases was obvious after resection, and argon ion coagulation and electrothermal biopsy forceps were successfully used to stop bleeding. No perforation, late bleeding, or operation-related death occurred. Postoperative pathology was in good agreement with preoperative ultrasound microprobe diagnosis (P < 0.01). The average hospital stay was (5.0 ± 2.1) d. During the follow-up period, no relapse occurred.Conclusion EMBM has a high monolithic resection rate for small superficial submucosal bulges without serious adverse complications. Ultrasound microprobe combined with EMBM for the treatment of small esophageal SMTs is a safe, effective, economically and feasible method.
