摘要随着现有手术技术、器械设备及治疗理念的不断更新进步，越来越多的医疗中心开始对于累及盆腔多器官及复发性盆腔恶性肿瘤的患者开展更加积极的扩大切除手术。扩大手术范围可以提高切缘阴性比率，实现肿瘤的R 0切除，有效改善患者预后并延长生存时间。因此，盆腔脏器联合切除术对于局部晚期的盆腔恶性肿瘤患者，已经逐渐成为标准的手术方式。目前，在开展盆腔脏器联合切除手术过程中，面临的主要问题仍然是患者术中和术后并发症发生率及病死率偏高以及长期生活质量较低。对于盆腔脏器联合切除术后并发症的相关研究，现逐渐聚焦于盆腔术后残存的巨大空腔，这可能是此类并发症的重要诱因，并由此提出了“空盆腔综合征”这一概念。本文在汇总空盆腔综合征相关文献基础上，分析其发生的原因可能为盆腔脏器联合切除术后，封闭的盆腔残腔随着空腔内空气被逐渐吸收、细菌繁殖及积液富集等过程而形成持续存在的负压，进而对整个腹盆腔内器官分布产生影响；同时，物理过程在参与空盆腔综合征的发生过程中是否也发挥着作用，有待探讨。汇总提出，其诊断主要依据患者病史、临床表现及影像学征象，而盆腔脏器切除手术史是病史诊断中最重要的指标。在预防措施上，首先应识别空盆腔综合征发生的高危人群，进而采取精准而个体化的预防措施；各种新型生物材料较传统的人体组织填充，在预防性盆腔填充方面更具优势；肠系膜对于小肠形态、蠕动和排列具有重要作用，通过保护肠系膜结构、恢复或重建肠系膜形态等方法，减少小肠异位入盆腔的机会，应获得更多关注。在治疗措施上，目前尚缺乏空盆腔综合征的标准治疗路径。

abstractsWith the development of existing surgical techniques, equipment and treatment concepts, more and more medical centers begin to carry out extensive resection for recurrent pelvic malignant tumors or those with multivisceral invasion. Exenteration may facilitate curative resection and improve the outcome of the patients. Therefore, pelvic exenteration has gradually become the standard of care for locally advanced pelvic malignancies. At present, pelvic exenteration leads to high intraoperative and postoperative complications and mortality, and therefore compromise the safety and long-term quality of life. Cumulating evidences suggest remnant cavity after exenteration might trigger the pathophysiological process and cause downstream complications which can be defined as empty pelvis syndrome. The literature related to empty pelvic syndrome was summarized, the possible cause of empty pelvic syndrome was analyzed. After the pelvic exenteration, the closed pelvic residual cavity formed continuous negative pressure with the gradual absorption of air in the cavity, bacterial propagation, and accumulation of fluid, which had an impact on the distribution of organs in the abdominal and pelvic cavity. At the same time, whether physical processes also play a role in the occurrence of empty pelvic syndrome remains to be explored. It is concluded that the diagnosis is mainly based on the patient's medical history, clinical manifestations and radiological findings, and the history of pelvic exenteration is the most important indicator in the diagnosis. In terms of prevention measures, we should identify the high-risk groups of the occurrence of empty pelvic syndrome, and then take accurate and individualized preventive measures. Various new biomaterials have more advantages in preventive pelvic cavity filling than traditional human tissue filling. Mesentery plays an important role in the morphology, peristalsis and arrangement of the small intestine. More attention should be paid to reducing the ectopic placement of the small intestine into the pelvic cavity by protecting the mesentery structure and restoring or rebuilding the mesentery morphology. In terms of treatment measures, there is still a lack of standard treatment pathway for empty pelvic syndrome.
