Clinical data of a patient with severe rectal burn induced by a hot normal saline enema. (A) Wounds on the buttocks before treatment in our hospital. (B) Wounds after 4 weeks of treatment. (C) Colonoscopic appearance of the rectum before treatment in our hospital. (D) The colonoscope could be advanced to the sigmoid colon at 4 weeks of treatment. (E) At 2 months after injury, an impassable stricture was found 5 cm above the anal verge. (F) Iodine angiography of lower digestive tract shows the stricture on the rectum (blue triangle). (G) Histologic examination (x40 HPF (high power field)). The red triangle shows normal mucosa whereas the red dotted circle shows chronic inflammation and fibrosis of the mucosa. (H) Specimen of the rectum and ovarian cyst (green arrows show the stricture of the rectum). (A colour version of this figure appears in the online version of this article.)

Second-degree burn scars were seen on both buttocks (Figure 1A). However, the colonoscope could not be advanced beyond 10 cm above the anal verge due to luminal narrowing (Figure 1C). By Week 4 of treatment, the buttock wounds had almost healed (Figure 1B). Although the lumina was still relatively narrow, the colonoscope could be advanced to the sigmoid colon (Figure 1D). She underwent colonoscopy that revealed an impassable stricture 5 cm above the anal verge (Figure 1E). Iodine angiography of the lower digestive tract showed that there was a stricture on the rectum (Figure 1F). Finally, we performed laparoscopic proctectomy (low anterior resection) with temporary terminal ileostomy and right oophorocystectomy 2 months after her injury (Figure 1G and H).
