摘要

在临床实践和科学文献中,关于根治性膀胱切除术合并膀胱成形术患者尿肠储存库肿瘤发生的资料很少。这类肿瘤的一个特点是在形成复发之前有很长的潜伏期,从4年到32年不等。本文描述了1951年一例小肠新囊肿瘤患者的临床病例。从患者病史来看,根治性膀胱切除术合并回肠成形术后有长期血尿(2年)。随着严重贫血的发展,血尿强度增加,形成大量血尿。mri、ct、超声及有创诊断检查均未见肿瘤。病人接受诊断性剖腹手术,在小肠输尿管-贮液吻合处发现肿瘤。切除小肠储层,输尿管移植。切除的肿瘤形态图为中等分化的尿路上皮癌。小肠尿库继发性肿瘤较为少见,具有腺癌的结构。它们发生的机制目前尚未得到充分的研究。根治性膀胱切除术和回肠成形术后患者的动态监测应在专门的中心进行。

The probability of developing a tumor in the small intestine neocyst
In clinical practice and scientific literature, there is very little data on the occurrence of tumors in the urinary intestinal reservoirs in patients after radical cystectomy with cystoplasty. A characteristic feature of such tumors is a long latent period before the formation of a relapse from 4 to 32 years.The article describes a clinical case of a 1951 patient with a tumor of a small intestinal neocyst. From the patient’s history, there is a long-term hematuria (for 2 years) after radical cystectomy with ileocystoplasty. The intensity of hematuria increased to the formation of profuse with the development of severe anemia. During the examination according to magnetic resonance imaging, computed tomography, ultrasound and invasive diagnostic examinations, no tumor was detected. The patient underwent a diagnostic laparotomy, a tumor was found in the area of ureteral-reservoir anastomosis of the small intestine neocyst. Resection of the small intestine reservoir and ureteral transplantation was performed. The morphological picture of the removed tumor is urothelial cancer of moderate differentiation.Secondary tumors of the small intestinal urinary reservoirs are rare and have the structure of adenocarcinoma. The mechanisms of their occurrence have not been fully studied at the moment. Dynamic monitoring of patients after radical cystectomy and ileocystoplasty should be carried out in a specialized center.
