Impact of cap-assisted colonoscopy during transendoscopic enteral tubing: A randomized controlled trial

Figure 1 Procedure-related colonic transendoscopic enteral tubing. A: It is difficult to find the lumen after the tube is inserted in some subjects because of the gathering of colonic folds and acute angle of colonic lumen caused by the transendoscopic enteral tube pulling; B: Cap-assisted colonoscopy uses a transparent plastic cap attached to the tip of the colonoscope to flatten the semilunar folds and improve mucosal exposure.

Figure 3 Relationship between the number of endoscopic clips and retention time of transendoscopic enteral tube. With the increased number of endoscopic clips, the retention time of transendoscopic enteral tube was prolonged (P < 0.001). After pairwise comparisons, subjects with four, three, or two clips had longer retention times than subjects with one titanium clip (4 vs 1, adjusted P < 0.001; 3 vs 1, adjusted P < 0.001; 2 vs 1, adjusted P = 0.035); and also, longer than patients with two clips (4 vs 2, adjusted P = 0.011; 3 vs 2, adjusted P = 0.036). But compared to three and four clips, there was no significant difference (adjusted P = 1.000). ^aP < 0.05, ^bP < 0.001. Data are presented as the median (range).
