IDDF2020-ABS-0216 Clinical analysis of surgical intervention in the treatment of T4 colorectal cancer with peritoneal carcinomatosis
do a biopsy. So, we tracked some patients with colon ulcer in order to know the etiology of these colon ulcers. Methods A total of 32 cases were enrolled. The mean age was (46.3 ± 14.8) years old (range, 21-70 years). The ratio of male to female was 9:7. The main reasons for patients. Undergoing colonoscopy were abdominal pain, diarrhea, and bloody purulent stool. The symptoms lasted for at least a month or more. The basic information, medical history, clinical manifestations, computed
... , computed tomography (CT), endoscopy of the patients and pathological examination were analyzed. Results The 32 patients' colonoscopy showed isolate or multiple colon ulcer. At the same time, we did a biopsy. The histopathology showed mucosal chronic inflammation. Combined with the detailed medical history, lab examination, abdominal CT and colonoscopy, we made the initial diagnosis. 8(25%) were NSAIDs-related colonic ulcer (figure 1). 6 (18.8%) were ischemic bowel disease. 3(9.4%) were allergic purpura. 2(6.3%) were Behcet' disease. 1(3.1%) was Wegener's granulomatosis (figure 2). There are 12 cases, we did not find a clear etiology of colonic ulcer. We did colonoscopy and multi-slice biopsy for all the patients after 3 months. The 20 patients, who had an initial diagnosis, the colon ulcer changed small even disappear after treatment. The other 12 patients, who had no initial diagnosis without any treatment, 6 of them had no changes in the lesions. The histopathology showed 3 were tuberculosis, 2 developed typical ulcerative colitis, 1 was lymphoma. The ulcerations of the other 3 with no initial diagnosis changed small. But the histopathology showed nonspecific mucosal chronic inflammation. The remaining 3, the lesions had disappeared. The follow-up continues. Conclusions There are various manifestations of colonic ulcer with colonoscopy. A detailed medical history is helpful for our diagnosis. The follow-up is important for no reason colonic ulcer. We should not diagnose and use medicine blindly.
