Venous hemangioma of the mesoappendix: Report of a case and a brief review of the Japanese literature

We present herein the rare case of a 48-year-old man in whom an abdominal mass, revealed by celiotomy to be a solid tumor of the mesoappendix, was histologically diagnosed as having a venous hemangioma. To our knowledge, only 18 cases of mesenteric hemangioma have been reported in Japan, including the present case. However, establishing a correct diagnosis preoperatively is extremely difficult despite advanced imaging techniques. In fact, a mesenteric mass was diagnosed preoperatively in only 3 of these 18 cases. Complete excision with or without bowel resection was performed in 16 cases. Interestingly, the histological diagnosis of all the previous cases was cavernous hemangioma, confirming that this report decuments the first case of venous hemangioma of the mesentery in the Japanese literature.     

内皮素-1对高血压病患者肠系膜动脉平滑肌细胞钙激活钾通道活性的影响

目的　探讨内皮素 1(ET1)对高血压病患者血管平滑肌细胞KCa通道活性的影响。方法　选择高血压病患者 18例 ,血压正常者 17例 ,两组患者均于腹部手术时取肠系膜动脉小分支用酶消化法获得单个血管平滑肌细胞。以膜片钳技术检测KCa通道的活性 ,记录不同钳制电压下单通道电流的平均开放时间 (To)、平均关闭时间 (Tc)、平均开放概率 (Po)、电流幅值 (Am) ,并绘制成电流 电压关系曲线。再分别加入Ca2 + (10 -8、10 -7、10 -6mol/L)、ET1(2× 10 9mol/L、4×10 9mol/L、6× 10 9mol/L、8× 10 9mol/L)后检测To、Tc、Po、Am等参数变化。结果　①高血压病患者KCa通道活性变化 :于细胞内面向外膜片下 ,在对称性高钾液中 ,高血压病组KCa通道平均开放概率增加 ,关闭时间延长、开放时间缩短。在浴液中分别加入Ca2 + 后 ,两组KCa通道均被明显激活 ,但血压正常组Po的增加显著高于高血压病组 (P <0 .0 0 1)。②ET1对高血压病患者KCa通道活性的影响 :血压正常者在内面向外式膜片下 ,Po、Tc均先增加后降低 ,显示低浓度时兴奋、高浓度时抑制 ,然而高血压病患者肠系膜血管平滑肌KCa通道对ET1则缺乏反应。结论　高血压病患者肠系膜动脉平滑肌细胞KCa通道活性明显高于血压正常者 ,但对Ca2 + 的敏感性降低。ET1对高血压病人KC     

先行钩突切断的胰十二指肠切除术

目的 介绍一种新的胰十二指肠切除方法.方法 当肿瘤横跨在门静脉前方、肿瘤侵犯肠系膜上动脉的情况不明和有异常肝动脉起源的可能时,先行钩突切断可以避免手术中出现尴尬局面.在探查无远处和肝脏转移情况下,打开胃结肠韧带并作Kocher切口充分暴露胰腺后,先切断钩突系膜,如此时发现肿瘤累及肠系膜上动脉,则终止根治性手术.在有异位肝动脉起源时,本方法可避免意外肝动脉损伤;当肿瘤病灶横跨胰颈时,采用本方法可保证肿瘤的切除,并保护脾静脉不受损伤.结果 2004年6月到2006年5月,9例病人按上述方法行胰十二指肠切除术,男性6例,女性3例,平均年龄(60.5±12.3)岁.9例手术无围手术期死亡.平均手术时间6.5 h,同期其他胰十二指肠切除术平均耗时5.2 h,差异有显著性(P＜0.05).平均失血量350 ml,未较同期胰十二指肠切除术明显增加(322 ml,P＞0.05).术后并发症发牛率(33.3%vs 26.9%,P＞0.05)无明显增加.结论 先行钩突切除的胰十二指肠切除术对有经验的胰腺外科医生足一个安全的手术.     

Ischaemic changes in human mesenteric lymph nodes

Lymph node lesions attributable to ischaemia are described in the mesenteric nodes from 10 patients with volvulus of the small and large bowel. Frank infarction, the microanatomy of which differs from that seen in superficial lymph nodes, is one of the nodal lesions evoked by ischaemia. Two others in the form of lymphocyte depletion and capsular hypervascularity also appear to result from vascular occlusion. These three lesions were also found in nodes associated with 'primary' venous and arterial infarction of the bowel mucosa, but not in non-vascular diseases of the small bowel or colon. The enhanced frequency of infarction in volvulus with mucosal necrosis, as opposed to cases with 'primary' vascular thromboses suggest that ischaemic lymph node changes are more frequent when several sets of vessels are occluded. Distension of lymph node sinuses, erythrocyte extravasation, and dilatation of small intranodal vessels were not restricted to vascular cases, and appear to be less specific reactions to ischaemia. The range of ischaemia-induced reactions is wider than has hitherto been recognized in human lymph nodes.

急性肠系膜上静脉血栓形成的诊治体会(附29例报告)

目的 探讨急性肠系膜上静脉血栓形成（SMVT）的诊治方法.方法 回顾性分析我院1990年1月～2005年6月间收治的29例SMVT患者的临床资料.结果 29例SMVT患者,年龄18～74岁（平均61.2岁）.主要症状有腹痛、腹胀、呕吐、发热、呕血和便血.主要体征有腹部膨隆、肠鸣音减少、腹膜刺激征、腹穿抽出血性液、白细胞计数升高.误诊率72.4%（21/29）,复发率24.1%（7/29）,死亡率27.6%（8/29）.结论 SMVT无特异性的临床表现,容易误诊.螺旋CT确诊率高,应该作为SMVT诊断的首选检查.早期诊断、早期进行抗凝治疗是降低死亡率和提高治愈率的关键,术后抗凝同样重要.发生肠坏死时,应进行以手术治疗为主的综合治疗.     

Sonographic findings in two cases of lymphangioma of the mesocolon in adults

Lymphangioma of the mesocolon is very rare. We report two cases of surgically resected and histologically proven mesocolic lymphangioma in adults. In both cases, ultrasound revealed a large cystic mass with multiple thin septa in the lower abdomen. A peculiar finding was the large craniocaudal sliding movement of the mass synchronized with the patient's respiration, which was a clue to the diagnosis of mesenteric lymphangioma. © 2017 Wiley Periodicals, Inc.

腹腔镜结肠癌全系膜切除术临床疗效观察及预后探讨

目的探讨结腹腔镜肠癌全结肠系膜切除术(complete mesocolic excision,CME)与开腹手术对结肠癌(colon cancer,CC)患者的临床疗效和预后的影响。方法选取2016年8月至2019年8月我院普外科收治的84例CC患者,按照手术方式的不同分为腹腔镜组和开腹组。比较两组患者术中手术时间、出血量、淋巴结清扫数量等指标,术后通气时间、住院时间和并发症发生率等指标,长期随访局部复发率、远处转移率、无瘤生存率以及生存质量FACT-G评分。结果腹腔镜组患者术中出血量、术后通气时间、住院时间以及并发症发生率显著低于开腹组,手术时间长于开腹组,各阶段生存质量评分明显优于对照组(P<0.05);两组间淋巴结清扫数量、远处转移率、局部复发率及无瘤生存率等差异无统计学意义(P>0.05)。结论结肠癌腹腔镜CME较开放手术具有明显优势,患者预后良好,近期疗效满意,值得推广。
