Abstract:
Objective:To investigate the value of the water pressure method (WPM) for endoscopic submucosal dissection (ESD) of difficult early gastrointestinal cancer.Methods:Clinical data of 7 patients with difficult early gastrointestinal cancer who underwent WPM-ESD at Digestive Endoscopy Center of Jiangsu Province Hospital of Chinese Medicine from April 2023 to April 2024 were retrospectively collected. Operation time, complete resection rate and complications were recorded.Results:WPM-ESD was successfully completed in all 7 cases. According to the lesion location and factors for difficulty, there were 2 cases of early esophageal cancer (1 case with remarkable external compression, and the other with remarkable hyperkeratosis), 1 case of early gastric cancer (a large lesion located at the greater curvature), 1 case of early descending duodenal cancer (severe submucosal fibrosis due to a history of two sessions of biopsies), 2 cases of early colon cancer (1 case with severe submucosal adipose deposition, and the other with deep submucosal invasion ), and 1 case of early rectal cancer (close to the dentate line). Operation time ranged from 15-85 min. Only 1 case required supplemental rubber-band traction. Complete resection was achieved in all 7 cases. Two patients developed fever postoperatively; no perforation, bleeding or other complications were observed.Conclusion:WPM demonstrates feasibility and efficacy for ESD in difficult early gastrointestinal cancer.
