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。
ObjectiveTo summarize experiences of laparoscopic extralevator abdominoperineal excision (ELAPE) in treatment of advanced low rectal cancer. MethodsThe clinical data of 46 patients with advanced low rectal cancer underwent laparoscopic ELAPE in our center from January 2012 to May 2015 were retrospectively analyzed.During the procedures,the anus and its surrounding tissue were individually resected by perineal approach with jackknife position.The pelvic perinium was closed laparoscopically.The operation time,intraoperative blood loss,retrieval of lymph nodes,radial margin,and postoperative complications were recorded. ResultsThe procedures were successfully performed without any intraoperative complications,complications associated with laparoscopy,or conversion to the open approach.The operation time was (175.3±26.5) min.The intraoperative blood loss was (55.7±28.6) mL.The number of lymph node retrieval was 16.3±7.7.No positive radial margin was identified. ConclusionSufficient resection of circumferential tissue,lower intraoperative perforation rate and satisfactory circumferential margin-negative rate could be achieved by laparoscopic ELAPE in treatment of advanced low rectal cancer.
