In managing 21 patients with benign ulcers of the rectum, there were seven patients with acute bleeding ulcers and two with acute rectal necrosis. Acute, bleeding ulcers of the rectum are associated with serious illness or injury, similar to those thought to cause stress ulcers of the stomach and duodenum. Rectal prolapse, complete or incomplete, is the condition most commonly associated with chronic, benign ulcers of the rectum. Repair of the rectal prolapse was successful treatment. Two patients had a tight muscular stenosis at the anorectal ring. This appeared to be a causative factor as complete healing occurred after myotomy.
在治疗21例直肠良性溃疡患者时，有7例急性出血性溃疡患者和2例急性直肠坏死患者。直肠急性出血性溃疡与严重疾病或损伤有关，类似于那些被认为会导致胃和十二指肠应激性溃疡的情况。直肠脱垂，完全或不完全脱垂，是最常与慢性直肠良性溃疡相关的病症。直肠脱垂修复术是成功的治疗方法。2例患者在肛门直肠环处有紧密的肌肉狭窄。这似乎是一个致病因素，因为在进行肌切开术后溃疡完全愈合。
