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.
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。
ObjectiveTo introduce the advances in diagnosis and treatment of superior mesenteric artery syndrome (SMAS). MethodsLiteratures about SMAS published in domestic and abroad were collected and reviewed. ResultsSMAS was a rare medical condition characterized by acute or chronic ileus resulting from vascular compression of the third part of the duodenum by superior mesenteric artery. Images of upper gastrointestinal series, CT, MRI, and color Doppler ultrasonography were the major methods of diagnosing the syndrome and the upper gastrointestinal series was the most important. Conservative approaches were usually preferred to the treatment of SMAS. Surgery was performed on symptomatic patients when conservative treatment failed, and duodenojejunostomy was the best surgical procedure. ConclusionAwareness of the clinical and imaging features may be helpful to diagnosis and treatment of SMAS, and reasonable therapy shall include etiological treatment and relief of the obstruction by conservative treatment or surgery.
Objective To compare efficacy of laparoscopic and open duodenal circular drainage operation for superior mesenteric artery compressing syndrome (SMACS). Methods From December 2012 to December 2015, the clinical data of 23 cases of laparoscopic duodenal circular drainage operation (laparoscope group) and 28 cases of open duodenal circular drainage operation (open group) were analyzed. The operation time, intraoperative bleeding, postoperative ambulation time, postoperative analgesics usage, postoperative the first exhaust time, postoperative the first feeding time, postoperative hospitalization time and postoperative incidence of complications were compared. The patients were followed up to confirm the effect after the operation. Results There were no differences of the age, sex, and body weight index between the laparoscope group and the open group (P>0.05). The operation time had no significant difference between these two groups (P>0.05). Compared with the open group, the intraoperative bleeding was less (P<0.05), the postoperative ambulation time, postoperative the first exhaust time, postoperative the first feeding time, postoperative hospitalization time were shorter (P<0.05), the rates of postoperative analgesics usage, incision infection, pulmonary infection, and intestinal obstruction were lower (P<0.05) in the laparoscope group. The rates of anastomotic leakage and anastomotic bleeding, and total postoperative complications rate had no significant differences between these two groups (P>0.05). All the patients were followed up for 8–36 months. The clinical symptoms disappeared and the body weight increased to normal level in the two groups. Conclusions Preliminary results of in this study show that laparoscopic duodenal circular drainage operation in treatment of SMACS has some advantages such as less trauma, faster recovery, fewer complications and shorter hospitalization time. Laparoscopy will be an ideal choice for treatment of SMACS.
