目的 提高对成人系统性Epstein-Barr(EB)病毒阳性T细胞淋巴组织增殖性疾病(ASEBV+T-LPD)肠道病变的认识。 方法 报道2012年3月-10月我院收治的2例以肠道病变为首发表现的ASEBV+T-LPD,并结合3例文献报道进行分析讨论。 结果 2例成人患者以腹泻为主要表现,伴有发热、淋巴结长大,初期分别误诊为结核及肠道感染,淋巴结病检提示多克隆EBER+的T淋巴细胞浸润,确诊ASEBV+T-LPD。例1经3 周期GLIDE方案(吉西他滨+门冬酰胺酶+异环磷酰胺+地塞米松+依托泊苷)化学疗法(化疗)后疾病进展,死于肺部感染。例2经干扰素联合抗病毒药物治疗,病情稳定。复习文献目前仅3例以肠道病变为首发表现的ASEBV+T-LPD被报道,早期均被误诊为炎性肠病或感染,3例均出现肠道穿孔或大出血等并发症,其中2例死亡。 结论 成人系统性EB病毒阳性T细胞淋巴组织增殖性疾病的肠道病变较为罕见,容易误诊为结核及炎性肠病。部分患者病情进展迅速,可出现肠道穿孔及消化道大出血等致死性并发症,死亡率高,预后差。确诊本病需密切结合临床和病理学检查。常规化疗及抗病毒治疗仅部分有效,不能维持长期缓解。
Objective To determine the feasibility, safety, and efficacy of common pedicle screw placement under direct vision combined with dome shaped decompression via small incision for double segment thoracolumbar fracture with nerve injury. Methods A retrospective analysis was performed on the clinical data of 32 patients with double segment thoracolumbar fracture with nerve injury undergoing common pedicle screw placement under direct vision combined with dome shaped decompression via small incision between November 2011 and November 2015 (combined surgery group), and another 32 patients undergoing traditional open pedicle screw fixation surgery (traditional surgery group). There was no significant difference in gender, age, cause of injury, time of injury-to-surgery, injury segments and Frankel classification of neurological function between two groups (P>0.05). The length of soft tissue dissection, the operative time, the blood loss during surgery, the postoperative drainage, the visual analogue scale (VAS) of incision after surgery, and recovery of neurological function after surgery were evaluated. Results All cases were followed up 9 to 12 months (mean, 10.5 months) in combined surgery group, and 8 to 12 months (mean, 9.8 months) in traditional surgery group. The length of soft tissue dissection, the operative time, the blood loss during surgery, the postoperative drainage, and the postoperative VAS score in the combined surgery group were significantly better than those in the traditional surgery group (P<0.05). Dural rupture during surgery and pedicle screw pulling-out at 6 months after surgery occurred in 2 cases and 1 case of the combined surgery group; dural rupture during surgery occurred in 1 case of the traditional surgery group. The X-ray films showed good decompression, and fracture healing; A certain degree of neurological function recovery was achieved in two groups. Conclusion Common pedicle screw placement under direct vision combined with dome shaped decompression via small incision can significantly reduce iatrogenic trauma and provide good nerve decompression. Therefore, it is a safe, effective, and minimally invasive treatment method for double segment thoracolumbar fracture with neurological injury.
