目的 探讨胰头癌侵犯肠系膜上动脉时行根治性切除的可行性。方法 采用联合将受侵犯的肠系膜上动脉一并切除的胰十二指肠切除术，肠系膜上动脉断端与腹主动脉端侧吻合方式重建。 结果 患者术后恢复顺利，已随访14个月，仍存活。 结论 肠系膜上动脉侵犯的胰头癌仍可行扩大的胰十二指肠切除术，并可延长患者的生存时间和提高生活质量。
目的总结急性肠系膜上动脉缺血性疾病的外科治疗经验。 方法对黄石市中心医院2002年1月至2013年6月期间收治的41例急性肠系膜上动脉缺血性疾病患者的临床资料进行回顾性分析。 结果41例急性肠系膜上动脉缺血性疾病患者中，行手术治疗40例（术中死亡2例），行介入溶栓治疗1例。术后出现短肠综合征9例，死亡19例。出院后27例患者获访，随访时间为1周～2年（平均随访时间为1.4年）。随访期间，因家属放弃治疗而于家中死亡7例，转院后于他院死亡4例，3例未愈或复发，13例痊愈（1例行介入溶栓治疗）。 结论急性肠系膜上动脉缺血性疾病的不同进展阶段其临床特征有所差异，术前CT血管造影（CTA）检查的意义重大。早期诊断、早期治疗、根据病情不同阶段选择合适的治疗方案（手术、介入治疗、药物治疗等）是降低死亡率的关键。
目的 探讨血管介入治疗在急性动脉缺血性肠病早期阶段的价值及应用方法。方法 笔者所在医院2005年8月至2011年12月期间共收治急性动脉缺血性肠病患者9例，其中2008年以前的6例行传统开腹手术治疗，2008年以后的3例患者，在短期内确诊并及时进行了溶栓或取栓治疗。结果 开腹手术治疗的6例患者中，行单纯肠系膜上动脉取栓1例，单纯坏死肠管切除3例，肠系膜上动脉取栓加坏死肠管切除2例；手术后1周内死亡2例（死于多脏器功能衰竭），半年后因短肠综合征死亡1例。行介入治疗的3例患者中，行经导管溶栓治疗2例，球囊取栓加溶栓治疗1例；术后均恢复良好，顺利出院； 术后分别随访6个月、9个月和2年，其中1例术后9个月因脑梗塞死亡。结论 血管介入治疗在急性动脉缺血性肠病的早期诊治方面具有明显的优势，一旦有可疑患者，应迅速进行影像学和血液学方面的检查以明确诊断，非创伤性血管成像技术（CTA）和血管造影（DSA）被认为是最有价值的诊断方法。明确诊断后，专业的血管外科医师的早期干预可以明显改善患者的预后。
ObjectiveTo explore the pathogenesis, diagnosis and treatment of superior mesenteric artery syndrome (SMAS) complicated with Wernicke encephalopathy (WE). MethodsThe clinical data of 11 cases of SMAS patients complicated with WE were retrospectively analyzed. ResultsOf 9 SMAS patients complicated with WE, 8 patients were gradually awake and the time of consciousness recovery was from 7 d to 9 weeks (mean 5.2 weeks). Another 1 patient died of multiple organ failure attributed to severe condition. The symptoms of ophthalmopegia and ataxia in the rest 2 patients improved. All of symptoms such as ataxia, nystagmus, tinnitus, nausea, and sweating gradually disappeared. The nystagmus disappeared from 3 h to 4 d (mean 2.3 d) in five patients and the ataxia disappeared from 3 d to 12 weeks (mean 7.0 weeks) in 4 patients. The tinnitus, nausea, and sweating in 6 patients disappeared within 1 week. ConclusionImproving the understanding of SMAS complicated with WE is important during clinical practice and early diagnosis and intervention is the key point for a good prognosis.
ObjectiveTo explore the feasibility and safety of modified semi-ex vivo small intestinal autotransplantation (IAT) in patients with distal cholangiocarcinoma (CC) involving mesenteric root. MethodThe clinicopathologic data of the patient with relapse after CC surgery admitted to Sichuan Provincial People’s Hospital on October 2022 were retrospectively analyzed. ResultsThe patient was a 40 years old male. The preoperative imaging showed that the superior mesenteric artery (SMA) and jejunal artery was surrounded by the tumor. The preoperative condition was good and the heart, lung, liver, and kidney functions were normal. The patient could tolerate surgery, then the modified semi-ex vivo IAT was performed. The patient recovered well after surgery and discharged on the 14th postoperative day. The postoperative pathological diagnosis result showed that it was CC. The patient was well and without recurrence or metastasis during following-up in the outpatient service for 5 months until April 2023. ConclusionsFrom the retrospective analysis of this case, it can be realized that the modified semi-ex vivo IAT for patients with tumor involving themesenteric root, it is safe and feasible. A treatment option can be provided for such patient.
目的探讨多排螺旋CT（MSCT）诊断胡桃夹现象的价值及临床意义。 方法对40例正常者（对照组）和12例胡桃夹现象患者（病例组）的腹部MSCT动脉期及延迟期图像进行后处理，测量腹主动脉与肠系膜上动脉（SMA）的夹角、左肾静脉层面腹主动脉前壁与SMA后壁的距离以及左肾静脉最小前后径，并观测左侧精索或卵巢静脉或左侧腰静脉是否扩张。 结果对照组及病例组所有观察对象MSCT均清晰显示左肾静脉、SMA及腹主动脉之间的立体解剖关系。对照组中无一例出现左肾静脉近段及左侧精索静脉或卵巢静脉或左侧腰静脉扩张；腹主动脉与SMA的平均夹角为71.4°，左肾静脉层面腹主动脉前壁与SMA后壁的平均距离为13.7 mm，左肾静脉平均最小前后径为6.9 mm。病例组中左肾静脉近段及左侧精索静脉或卵巢静脉扩张12例，左侧腰静脉扩张5例；腹主动脉与SMA的平均夹角为27.4°，左肾静脉层面腹主动脉前壁与SMA后壁的平均距离为3.8 mm，左肾静脉平均最小前后径为2.7 mm，近端肾静脉扩张。经两独立样本均数t检验，病例组腹主动脉与SMA的夹角、左肾静脉层面腹主动脉前壁与SMA后壁的距离及左肾静脉最小前后径均明显小于对照组（P＜0.05）。 结论MSCT可清晰显示SMA、腹主动脉和左肾静脉之间的解剖关系，对诊断胡桃夹现象具有很高的价值。
目的 探讨肠系膜上动脉压迫综合征的诊断和治疗方法。方法 对笔者所在医院2003年8月至2010年8月期间收治的16例肠系膜上动脉压迫综合征患者的临床资料进行回顾性分析。结果 16例肠系膜上动脉压迫综合征患者的临床表现主要为反复发作性进食后上腹部胀痛或隐痛、呕吐且呕吐后症状可缓解（12例），恶心、反酸及嗳气（13例），饭后饱胀感或腹胀（16例），以及食欲不振（13例）。16例患者均行上消化道造影检查明确诊断；3例行腹部彩色多普勒超声检查符合诊断；4例行CT检查排除十二指肠周围占位性病变。16例患者均先行非手术治疗，其中10例患者的腹痛缓解，呕吐消失，好转出院；另6例因治疗无效而行手术治疗，其中行Treitz韧带松解加十二指肠空肠侧侧吻合术2例，行十二指肠空肠Roux-en-Y吻合术3例，行胃大部分切除、胃空肠吻合术（BillrothⅡ式）1例。术后除1例行Treitz韧带松解加十二指肠空肠侧侧吻合术的患者仍有间断腹胀伴恶心外，其余患者均痊愈。结论 肠系膜上动脉压迫综合征主要表现为上腹部胀痛、呕吐、食欲不振及消瘦，确诊依赖于上消化道造影。对其治疗首选非手术治疗，对非手术治疗无效者可采用手术治疗，其中十二指肠空肠Roux-en-Y吻合术是一种有效、易行的手术方式。
Objective To evaluate the clinical efficacy and safety of endovascular therapy for spontaneous isolated superior mesenteric artery dissection (SISMAD). Methods The clinical data of 17 patients with SISMAD, who were treated at author's hospital during the period from March 2009 to May 2016, were retrospectively analyzed. According to the Sakamoto angiographic classification, patients were divided into typeⅠ (n=3), typeⅡ (n=5), and type Ⅲ (n=9). Three patients with type Ⅰ were treated with conservative treatment first, and then 2 were treated with endovascular therapy as the poor reaction. The other patients were treated with endovascular treatment right a way. Results Conservative treatment was success in 1 case, 16 patients were treated with endovascular treatment, the technical success rate was 100%, one stent was used in 11 patients and two stents were used in 5 patients, and the blood in the true lumen of superior mesenteric artery (SMA) restored, no major complications occurred. Seventeen patients were followed-up for 3-36 months (mean of 19 months) and the followed-up rate was 100%, no abdominal pain occurred in 17 cases, CTA showed that no dissecting aneurysm was observed and the stents were patent of SMA. Conclusion Interventional therapy is a safe and effective method for SISMAD.
