目的 探讨原发性骶前肿瘤的诊断及外科治疗。方法 回顾性分析徐州医学院附属医院普外科1980年1月至2012年7月期间收治的50例原发性骶前肿瘤患者的临床资料，并结合文献复习进行讨论。结果 原发性骶前肿瘤的术前诊断主要依靠直肠指检、B超、CT、MRI等相关检查。手术采用经骶尾部入路22例，经下腹部正中入路22例，经腹、骶尾部联合入路6例。肿瘤被完整切除33例，行部分切除10例，未切除7例。并发症有术中出血、直肠损伤，术后切口感染、脓肿形成等。结论 骶前肿瘤如无禁忌证均应行手术治疗。充分的术前评估、合理选择手术入路、多学科协作以及对术中和术后并发症的充分认识是手术成功的关键。
ObjectiveTo investigate the clinical characteristic and treatment of gastrointestinal neuroendocrine neoplasm. MethodsFrom January 2011 to July 2015, the clinical characteristic and treatment of 74 patients with gastrointestinal neuroendocrine neoplasm in The Affiliated Hospital of Xuzhou Medical College were retrospectively analyzed. ResultsCases of gastrointestinal neuroendocrine neoplasm were increasing year by year. This study includes statistics of 74 patients. The number of male and female were 47 and 27, the rate was 1.74:1, the median age was 57.5 years old ranging from 24 up to 82 years. Of all the 74 cases, there were 38 cases (51.4%) in the stomach, 23 cases (31.1%) in rectum, 12 cases (16.2%) in colon, 1 case in duodenum. Of all the 74 cases with clinical symptom information, non-functional symptom accounts for 95.9% (71/74), while functional symptom accounts only for 4.1% (3/74). There were treatment data of 74 cases, including 34 cases in radical surgery, 23 cases in endoscopic excision, 8 cases in local resection, 4 cases in palliative resection, and 5cases in conservative treatment. The lymphatic metastasis was associated with gender, tumor size, tumor depth of invasion and tumor differentiation (P < 0.05). There was no statistically significant between the lymphatic metastasis and tumor location (P > 0.05). Preoperative distant metastasis was associated with tumor size and tumor depth of invasion (P < 0.05). Syn had a higher positive rate than CgA (P < 0.01). The positive rate of Syn and CgA was respectively 96.1% (49/51) and 72.9% (35/48). Conciusions Cases of gastrointestinal neuroendocrine neoplasm are increasing year by year, of which men has a higher morbidity than women. Radical surgery and endoscopic resection are the main treatment methods. The Syn and CgA test are helpful to the diagnosis of gastrointestinal neuroendocrine neoplasm.
目的总结低位直肠癌采用柱状经腹会阴切除术（APR）的应用体会。 方法徐州医学院附属医院普通外科于2010年1月至2013年7月期间采用柱状APR治疗22例低位直肠癌患者（柱状APR组），并与同期行传统APR治疗的35例患者（传统APR组）进行对比，分析术中、术后和随访的各项指标。 结果与传统APR组比较，柱状APR组的环周切缘阳性率及术中穿孔率明显降低〔4.55%（1/22）比34.29%（12/35）和4.55%（1/22）比31.43%（11/35）〕，差异有统计学意义（P＜0.05）；2组手术时间、术中出血量、并发症发生率比较，差异无统计学意义（P＞0.05）。术后随访3～30个月（平均21个月），柱状APR组无肿瘤复发及远处转移患者，未见死亡病例；传统APR组出现盆底局部复发4例，远处转移3例，死亡2例。2组局部复发、远处转移及死亡率比较差异均无统计学意义（P＞0.05）。 结论柱状APR可以切除更多的肿瘤周围组织，降低环周切缘阳性率，减少术中肠穿孔的发生，降低局部复发。
