"Three cases with ICP were collected retrospectively. Once a perforation was detected, endoclips (ROCC-D-26-230-C, Micro-Tech, Nanjing, China) were used to closed the defect of the colon. Then a colonic TET (Diameter 2.7 mm, FMT-DT-F-27/1350, FMT medical, Nanjing, China) was planted inside the colon. The terminal end of the TET was put proximal to or near the location of the perforation. Then gas and fluid was sucked out through the TET with a syringe every 4 h (see Fig.  A–C). More details about the colonic TET were described in Fig. . How to implant the colonic TET was shown in the video published by our team previously []. Given the retrospective study design, this study was not registered in a public trial registry, and IRB approval and written consent was not applied for. The signed consent of implantation of the colonic TET as a regular procedure in China was obtained from the patients.Fig. 1A Perforation detected. B Endoclips applied to close the perforation. C Colonic TET was inserted into the colon after perforation closed with endoclips. Gas and fluid was sucked with a syringe though the TETFig. 2The colonic TET is showed in the figure, with an outer diameter of 2.7mm. The type is FMT-DT-F-27/1350. Three separate loops are designed on the terminal end of the tube, which contribute to the tube fixed to the colonic mucosa with endoclips (black arrow). Side-holes are also designed on the terminal end of the tube which help to drainage out gas and fluid"
