Metal stent combined with ileus drainage tube for the treatment of delayed rectal perforation: A case report

Figure 7 The pelvic free gas gradually decreased in the patient. A: Day 2 computed tomography (CT), Metal tubular shadows were observed in the rectal lumen, and a lot of gas was observed around the intestinal canal; B: Day 5 CT: a lot of free air was trapped behind the peritoneum and in the pelvis, but this was slightly resolved on day 5, as compared the amount of air on Day 2 CT slice; C: Day 10 CT: The free air in the peritoneal cavity and behind the peritoneum was significantly reduced as compared with that on Day 5 CT slice; D: Day 17 CT: No clear manifestation of the original rectal stent was observed. A little amount of free air trapped in the pelvis was absorbed as compared with that on the Day 10 CT slice.
