A multicenter randomized controlled trial evaluated the efficacy of transrectal drainage tubes (TDTS) in preventing postendoscopic submucosal dissection (PECS) in 224 patients. The results showed a significantly lower incidence of PECS in the TDT group (6.25%) compared to the non-TDT group (17.86%), with a relative risk of 0.350 (p = 0.008). Subgroup analyses indicated that TDTS were particularly effective in female patients, those with tumors smaller than 4 cm, left-sided lesions, and shorter procedure times.
