ABSTRACT

Objective:

To investigate the clinicopathological characteristics and cost-effectiveness of endoscopic resection and surgical resection for gastric schwannomas arising from the muscularis propria layer.

Methods:

Thirty-eight consecutive cases of gastric schwannomas diagnosed by histopathology between October 2011 and July 2016 were divided into the endoscopy group(including endoscopic submucosal excavation and endoscopic full-thickness resection) and the surgery group. Complications, complete resection rate and cost-effectiveness were analyzed.

Results:

The age was 52±10 years (range, 41-63 years) with 11(28.9%) males and 27(71.1%) females. The most common site of gastric schwannomas was the body (71.1%) and the antrum (21.1%). All 38(100%) lesions were protruded. The maximum diameter of the lesions was 2.5±1.2 cm (range 0.6-4.5 cm). Under endoscopic ultrasonography (EUS), 60.5% lesions were heterogeneous hypoechoic, and 15 (39.5%) hypoechoic. The complete resection rate of endoscopy group was 100.0% (17/17). The median operation time of the endoscopy group was 54 minutes. Perforations occurred in 11 patients (64.7%, 11/17), and metal clips or the nylon rope combined with metallic clips were used to close the defect in the endoscopy group. Compared with the surgery group, the length of hospital stay was significantly shorter (4.6±0.6 d VS 9.6±4.4 d, P<0.001); the time to the first fluid diet was significantly shorter (1.2±0.4 d VS 2.7±0.7 d, P<0.001), and the costs were significantly lower (21 965.0±9 342.4 yuan VS 34 253.3±10 520.9 yuan, P<0.001) in the endoscopy group. S100 immunoreactivity was present in all tumors. Local recurrence and distant metastasis did not occur during the median 34 months of follow-up.

Conclusions:

Endoscopic resection appears to be safe and effective for diagnosis and treatment of gastric schwannomas from the muscularis propria layer. The cost-effectiveness of endoscopic resection is significantly higher than surgical resection.
