Abstract
Background: This study aimed to investigate the clinical characteristics and esophageal motility of patients with gastric cardia submucosal tumors (SMTs) and the associated changes after endoscopic resection based on high-resolution impedance manometry (HRIM). Methods: From our electronic database, we identified patients who underwent pre-operative evaluation of gastric cardia SMTs between 2015 and 2023. All patients completed standardized symptom questionnaires and underwent endoscopic ultrasonography and HRIM. Endoscopic resection via submucosal dissection or submucosal tunnel endoscopic resection was performed, followed by esophagogastroduodenoscopy and HRIM three months later. Esophageal motility on HRIM was compared based on the updated Chicago Classification v4.0. Results: Thirty patients (mean age, 47.4 ± 12.8 years; male, 50%) were analyzed. Most patients were asymptomatic (43.3%), while others presented with epigastralgia, regurgitation, chest pain, or dysphagia. On endoscopic ultrasonography, the average tumor size was 16.7 ± 4.5 mm (range, 10.0–30.0 mm), and most tumors originated from the fourth layer (80%). On HRIM, eight patients (26.7%) had abnormal esophageal motility, including five with ineffective esophageal motility (IEM) and three with esophagogastric junction outflow obstruction. Complete resection was achieved in 25 of the 27 patients (92.6%) who underwent endoscopic treatment. Pathology revealed leiomyomas (96%) and gastrointestinal stromal tumors (4%). No significant differences in symptom profiles or HRIM parameters were observed after tumor resection. Three patients with pre-operative IEM exhibited normal motility at the follow-up HRIM. Conclusion: Up to 26.7% of patients with gastric cardia SMTs had abnormal esophageal motility on HRIM. Endoscopic resection of these SMTs was effective and safe and appeared to improve esophageal motility in patients with IEM.
