OBJECTIVE: To determine the feasibility and efficacy of single-channel gastroscopy, double-channel gastroscopy, and double gastroscopy in treating submucosal tumors in the cardia and gastric fundus.
METHODS: The data of 77 patients with submucosal tumors (SMTs) in the cardia and gastric fundus parts of the stomach who underwent single-channel gastroscopy, double-channel gastroscopy, and double gastroscopy were retrospectively analyzed. The observed therapeutic effect, complications, and local recurrence from these three groups were then compared.
RESULTS: All lesions were completely taken out under endoscopy, and the operation time for single-channel gastroscopy group was 20-90 min with an average of 44.5 min, and the postoperative hospitalization time was 5-9 days with an average of 7.5 days. The operation time for the double-channel gastroscopy group was 40-110 min with an average of 60.5 min, and the postoperative hospitalization time was 7-10 days with an average of 8.3 days, whereas the operation time of double gastroscopy group was 35-120 min with an average of 66.3 min, and the postoperative hospitalization time was 7-10 days with an average of 8.5 days. No patient was required to be transferred to the General Surgery Department for continuous treatment. Bleeding was noted from all the patients during operation, and hemostasis was performed successfully. Postoperative bleeding was not observed in any of the cases. Full-thickness resection was performed in all the three groups. No residual or recurrent lesions were detected via reexamination of gastroscopy in all the patients.
CONCLUSION: Single-channel gastroscopy, double-channel gastroscopy, and double gastroscopy present potential capability with distinctive advantages in the endoscopic treatment of submucosal tumors of the cardia and gastric fundus, and it also shows that appropriate operation methods should be selected based on the situation of an individual patient.
