Abstract:
Objective:To explore the strategies and complications of the submucosal tunneling endoscopic resection (STER) in the treatment of esophageal duplicated cyst (EDC).Methods:From January 2013 to December 2019, at Department of Gastroenterology, Taizhou Hospital of Zhejiang Province, the clinical data of 11 hospitalized patients with EDC diagnosed by pathological examination who underwent STER were collected. The clinical featured, computed tomography (CT) findings, endoscopic findings, postoperative efficacy, complications and pathological results after operation were summarized.Results:Among the 11 patients, there were 6 males and 5 females, the age ranged from 13 to 67 years, and the mean age was (43.0±18.2) years. One case presented with swallowing obstruction, 1 case with belching, 4 cases with upper abdominal pain, and the remaining 5 cases had no specific clinical symptoms. Under endoscopy, the lesions of 11 patients were hemispherical or mound-shaped with smooth surface submucosal masses in the esophageal cavity, which were soft to touch. Under endoscopic ultrasonography, they all appeared as hypoechoic masses with clear boundary located in the esophageal muscularis propria. The results of CT scan of 9 patients showed round low-density cystic masses, among them 7 cases showed mild enhancement. The maximum diameter of the cysts was 1.5 to 4.4 cm, with mean maximum diameter being (2.8±0.8) cm, and the maximum diameter of most patients (7 cases) were 2 to 3 cm. The other two patients showed only slightly thickened esophageal wall on CT. Five lesions occurred in the horizontal mediastinum of the lower esophagus. All the 11 patients underwent STER operation successfully, among them 6 patients received simple STER and the cysts were completely resected, and the other 5 patients received STER and cauterization with argon ion for the residual cyst wall. The pathological results after operation indicated that 6 cases were congenital esophageal cysts and 5 cases were bronchogenic cysts. The median follow-up time (range) of 11 patients was 42 months (12-86 months). Ten patients recovered well after the operation, and local recurrence, malignant transformation or metastasis were not found. One case had recurrence, and was treated with STER and cauterization with argon ion for residual cyst wall and cured. No complications such as bleeding, fistula, mediastinal infection or death occurred during and after operation in all the 11 patients.Conclusions:STER is a minimally invasive, safe and effective treatment for EDC, and may be a new treatment for EDC.
