Do We Perform a Perfect Endoscopic Hemostasis Prophylactically with Argon Plasma Coagulation in Colonic Endoscopic Mucosal Resection?
- Abstract
- BACKGROUND: Submucosal injection for endoscopic mucosal resection (EMR) may effect performing the prophylactic argon plasma coagulation (APC) of non-bleeding visible vessels on ulcer crater. AIMS: The purpose of this study was to evaluate the clinical features of visible vessels in iatrogenic ulcers over time after prophylactic APC in colonic EMR. PATIENTS AND METHODS: This study was designed as a prospective study. Between August and November 2013, a total of 40 patients who were admitted underwent prophylactic APC for non-bleeding visible vessels after colonic EMR. After confirming whether visible vessels were completely coagulated or not, the number of visible vessels in ulcers was counted over a specific time period, e.g. 1, 3, 5, or 7 min. RESULTS: The mean number of visible vessels was significantly higher at 5 min (0.85 ± 1.14) after EMR with prophylactic APC compared to 1 and 3 min (1 min: 0.28 ± 0.60, P < 0.001; 3 min: 0.65 ± 0.87, P = 0.02) and there was no significant difference between 5 and 7 min (P = 0.31). Multivariate analysis showed that the size of the iatrogenic ulcer after EMR was associated with the occurrence of visible vessels (ulcer size >1 vs. ≤0.5 cm: OR 27.32, 95% CI 2.86-infinity). CONCLUSIONS: A 5-min observation of the ulcer may be advantageous for the assessment of visible vessels after performing colonic EMR with prophylactic APC, and large (>1 cm) iatrogenic ulcers were associated with the occurrence of visible vessels after colonic EMR.
