高压氧综合治疗糖尿病性胃轻瘫患者的疗效观察

目的观察高压氧（HBO）联合吗丁啉综合治疗对糖尿病性胃轻瘫患者胃动素及胃排空时间的影响。方法采用随机数字表法将2000年10月至2004年10月间连续人院的糖尿病性胃轻瘫患者112例随机分为高压氧组和对照组各46例，HBO组在给予吗丁啉（每次10mg，每天3次，连用4周）的基础上加用HBO治疗，HBO采用多人氧舱，在舱内停留120min，压力为0．25MPa（2．5ATA），戴面罩吸人纯氧60min（30min各2次，中间休息10min吸人舱内空气），10次为1个疗程，共3个疗程，每疗程间隔3～5d（排除HBO治疗禁忌证）。对照组为单纯吗丁啉，每次10mg，每天3次，连用4周。45d分别对两组患者治疗前后胃动素、空腹血糖、胃排空时间及症状的改善各项指标进行研究对比。结果HBO组和对照组总有效率分别为92．9％和76．8％，症状的改善、胃动素及胃排空时间治疗组均优于对照组，差异有显著性（P〈0．05）。结论糖尿病性胃轻瘫患者在服用吗丁啉的基础上应用HBO可降低胃动素、加速胃排空时间，对临床症状的改善具有积极作用。     

Postinfectious gastroparesis related to autonomic failure: a case report

BACKGROUND AND AIM: Severe dysautonomia may be secondary to viral infections, resulting in impaired autoimmune, cardiovascular, urinary and digestive dysfunction. Herein, we present a case of a 31-year-old white female patient who had severe gastroparesis related to autonomic failure following an episode of acute gastroenteritis. This seems to be the first report providing thorough assessment of the enteric and autonomic nervous system by analysis of full-thickness small intestinal biopsies, cardiovagal testing and autopsy. HOSPITAL COURSE: This patient affected by a severe gastroparesis was treated with antiemetics, prokinetics, analgesics and gastric electrical stimulation to control symptoms. Nutritional support was made using jejunal feeding tube and, in the final stage of disease, with total parenteral nutrition. Autonomic studies revealed minimal heart rate variability and a disordered Valsalva manoeuvre although the enteric nervous system and the smooth muscle layer showed a normal appearance. Hospital courses were complicated by episodes of bacteraemia and fungemia. Serum antiphospholipid antibodies were noted but despite anticoagulation, she developed a pulmonary embolism and shortly thereafter the patient died. Autopsy revealed acute haemorrhagic Candida pneumonia with left main pulmonary artery thrombus. Sympathetic chain analysis revealed decreased myelinated axons with vacuolar degeneration and patchy inflammation consistent with Guillain-Barre syndrome. The evaluation of the enteric nervous system in the stomach and small bowel revealed no evidence of enteric neuropathy or myopathy. CONCLUSION: A Guillain-Barre-like disease with gastroparesis following acute gastroenteritis is supported by physiological and autonomic studies with histological findings.     

腹部术后胃瘫综合征的诊治体会

目的探讨腹部术后胃瘫的诊断及治疗.方法总结16例腹部术后胃瘫患者的临床资料进行回顾性分析.结果该组病例中男11例,女5例;年龄36～85岁,平均(60.50±15.76)岁.术前长期流出道梗阻、恶性肿瘤、胆道疾病、胰十二指肠切除术后,胃大部切除术后的病人发病率高.胃镜、X线口服造影及核素胃排空试验对术后胃瘫的诊断有价值,经保守治疗后胃肠动力一般在术后4周内恢复.结论该病是一种功能性疾病,一旦诊断成立,采取促动力药物在内的保守治疗是治疗的有效方法,不宜盲目手术.     

Simultaneous noninvasive evaluation of gastric emptying and orocaecal transit times

Summary The aim of the study was to use a novel combination of two methods for the simultaneous evaluation of two effects of oral cisapride in 10 diabetic patients with autonomic neuropathy; gastric emptying time was measured by following radio-opaque markers and orocaecal transit time by the sulphasalazine-sulphapridine method. The study was of double-blind, randomized, placebo-controlled, cross-over design.It was possible to evaluate the effect of a prokinetic drug on gastric emptying and orocaecal transit times using these two noninvasive techniques at the same time. Cisapride significantly reduced both the gastric emptying (1.2 h versus 2.1 h) and orocaecal tansit (5.9 h versus 7.7 h) times.     

The Effect of Continuous Intake of Lactobacillus gasseri OLL2716 on Mild to Moderate Delayed Gastric Emptying: A Randomized Controlled Study

Probiotics have been suggested to be effective for functional dyspepsia, but their effect on gastric motility is not clear. We evaluated the effect of Lactobacillus gasseri OLL2716 (LG21 strain) on mild to moderate delayed gastric emptying by a double-blind, parallel-group, placebo-controlled, randomized trial. Participants (n = 28) were randomly assigned to ingest LG21 strain-containing yogurt (LG21 strain group) or LG21 strain-free yogurt (placebo group) for 12 weeks. The ¹³C gastric emptying breath test was performed to measure the gastric emptying rate over time following ingestion of a liquid meal, and the time to reach the peak (Tmax) was used as an indicator of gastric emptying. We also measured the salivary amylase concentration, an indicator of autonomic dysfunction under stress. The per-protocol population (n = 27, male n = 4, female n = 23) was evaluated for efficacy. When a ≥30% reduction in the difference between participant’s Tmax and the Japanese mean Tmax was defined as an improvement, the odds ratio of improvement in delayed gastric emptying compared to placebo after 12 weeks was 4.1 (95% confidence interval, 0.8 to 20.2). Moreover, salivary amylase concentrations were significantly lower than in the placebo group, indicating an improvement in autonomic function. The present data were not enough to support the beneficial effects of the LG21 strain on delayed gastric emptying. However, if we define the odds ratio in further study investigated with a larger number of participants, LG21 strain might be expected to have some impact on delayed gastric emptying.     

中医药在糖尿病胃轻瘫治疗中的应用及思考

糖尿病胃轻瘫（DGP）发病率较高,药物治疗存在一定的局限性,部分患者可能出现一定的不良反应,这影响糖尿病的治疗。中药治疗DGP可以有效缓解患者症状,降低现有药物不良反应,辅助控制血糖。现代医家多利用辨证分型组方、经方验方及中成药进行辨病辨证治疗相结合,运用单味药、药对、中药提取物进行个体化治疗。现通过概述中药的多种组方思路,总结其优势,并对中药治疗DGP的现状进行思考与总结,以期中医药治疗DGP得到更好的发挥。

2型糖尿病患者胃排空影响因素及西沙必利治疗观察

 [目的]探讨2型糖尿病患者胃排空影响因素、单光子发射计算机断层摄影（SPECT）显影技术和B超在糖尿病性胃轻瘫诊断中的应用及西沙必利治疗效果.[方法]①对120例2型糖尿病进行临床分析.②120例2型糖尿病随机分为两组：A组应用核素^99mTc-SC标记固体试餐,SPECT显像技术检测胃半排空时间（T1/2）;B组予B超检测T1/2.两组均检测空腹血糖（FBG）和糖基化血红蛋白（HbA1c）.③胃T1/2延迟者予西沙必利30 mg,/d,疗程均为1个月,复查胃T1/2.[结果]①糖尿病性胃轻瘫的发生与年龄、病程、空腹血糖、糖基化血红蛋白、神经病变及微血管病变呈正相关（P＜0.01）;②A组60例患者中24例（40.0%）胃T1/2延迟;B组：60例患者中22例（36.7%）.两种检查方法的检出率差异无统计学意义（P＞0.05）;③西沙必利治疗A组有效率为91.7%,B组为90.9%.[结论]糖尿病性胃轻瘫与年龄、病程、高血糖、神经病变及微血管病变相关;SPECT显像技术与B超检出率相似,但不排除与病例数少有关.患者对这两种检查方法耐受性好,但SPECT显像技术费用高,不利于广泛开展,而B超价廉,易于临床使用.西沙必利是有力的促进胃动力的药物,对糖尿病性胃轻瘫有一定的改善胃排空的疗效.
