腹膜后、肠系膜和大网膜囊肿是一种罕见的腹部肿瘤，大约发生在105,000名住院患者中的1例。这些囊肿有相似的发病机制，主要可能是异位淋巴组织。腹膜后和肠系膜囊肿可以发生在十二指肠和直肠之间的任何地方，但最常见的是小肠系膜，尤其是回肠。它们可以表现为慢性腹痛、无痛性腹部肿块或急腹症。腹膜后或肠系膜囊肿最常见的物理表现是可压缩的腹部肿块，可横向移动，但不能纵向移动；大网膜囊肿可自由移动。诊断辅助手段包括腹部计算机断层扫描和超声波。上胃肠道(GI)系列检查、钡灌肠检查和静脉肾盂造影术排除了GI和泌尿生殖道囊肿和肿瘤。首选的治疗方法是眼球摘除；有时可能需要切除邻近的肠道。由于现代手术技术和后续程序，发病率和死亡率应该非常低。
Retroperitoneal, mesenteric, and omental cysts are rare abdominal tumors occurring in approximately one of 105,000 hospitalized patients. These cysts have a similar pathogenesis that primarily may be ectopic lymphatic tissue. Retroperitoneal and mesenteric cysts can occur anywhere in the area between the duodenum and rectum but are most common in the small-bowel mesentery, especially the ileum. They can appear as chronic abdominal pain, a painless abdominal mass, or acute abdomen. The most common physical finding of a retroperitoneal or mesenteric cyst is a compressible abdominal mass, movable transversely but not longitudinally; omental cysts are freely movable. Diagnostic aids include abdominal computed tomography and ultrasound. The upper gastro-intestinal (GI) tract series, barium enema examination, and intravenous pyelogram exclude GI and genitourinary cysts and tumors. Treatment of choice is enucleation; resection of the adjacent bowel may occasionally be necessary. Morbidity and mortality should be very low because of modern surgical techniques and follow-up procedures.
