RESUMEN
Objective:To investigate the safety and efficacy of submucosal tunnel docking endoscopic resection (SDER) for the treatment of giant submucosal tumors in the cardia.Methods:A retrospective analysis was performed on data of patients with giant submucosal tumors in the cardia who were treated with SDER at the endoscopy center of Zhongshan Hospital, Fudan University and Xuhui District Central Hospital from January 2021 to January 2022. The surgical records, postoperative pathology, complications, hospitalization, and follow-up were analyzed.Results:A total of 6 patients were included. The mean long diameter of the lesions was 4.0 cm, all of which were located in the cardia. All patients successfully underwent SDER treatment with a surgical time of 23-42 min. Postoperative pathology revealed that 4 cases were leiomyomas and 2 cases were gastrointestinal stromal tumors. All lesions were completely resected. The postoperative hospital stay was 3-5 d, and no serious complications occurred after surgery. All patients recovered on follow-up gastroscopy at 3 and 6 months postoperatively.Conclusion:The preliminary conclusion is that SDER for the treatment of giant submucosal tumors in the cardia is safe, effective.
RESUMEN
Objective:To evaluate the safety, efficacy and long-term survival of endoscopic submucosal dissection (ESD) for colorectal precancerous lesions and early cancer in the elderly over 80 years old.Methods:Clinical data of colorectal precancerous lesions and early cancer treated with ESD from January 2007 to December 2014 at Endoscopy Center of Zhongshan Hospital, Fudan University were retrospectively analyzed. A total of 721 patients with 778 lesions were included in this study. These patients were stratified by age: the super-elderly group (≥80 years old, 55 patients, 7.6%) and the non-super-elderly group (<80 years old, 666 patients, 92.4%). The outcomes of ESD, complication incidences, pathological characteristics, and long-term survival were compared between the two groups.Results:Except that the incidence of chronic concomitant diseases in the super-elderly group was significantly higher than that in the non-super-elderly group [54.5% (30/55) VS 31.5% (210/666), P<0.001], other baseline characteristics were not significantly different ( P>0.05). There were no significant differences in the complete resection rate [93.1%(54/58) VS 95.3%(686/720)], the R0 resection rate [89.7% (52/58) VS 93.2% (671/720)], the curative resection rate [84.5% (49/58) VS 90.3% (650/720)], the complication incidence [5.5% (3/55) VS 2.7%(18/666)], or the median hospitalization (2.98 days VS 2.54 days) between the two groups (all P>0.05). The three-year overall survival rates of the super-elderly group and non-super-elderly group were 95.8% and 98.0%, respectively, and the five-year overall survival rates were 85.1% and 97.4%, respectively. Conclusion:Colorectal ESD is safe and effective for elderly patients (age ≥80 years old) despite a significantly higher incidence of chronic concomitant diseases than that in the non-super-elderly patients.
