Predictors of delayed gastric emptying in diabetes.

OBJECTIVE: To define the predictors of the rate of gastric emptying in patients with diabetes. RESEARCH DESIGN AND METHODS: A total of 101 outpatients with diabetes (79 type 1 and 22 type 2) underwent measurements of gastric emptying of a solid/liquid meal (scintigraphy), upper gastrointestinal symptoms (questionnaire), glycemic control (blood glucose concentrations during gastric emptying measurement), and autonomic nerve function (cardiovascular reflexes). RESULTS: The gastric emptying of solid and/or liquid was delayed in 66 (65%) patients. Solid (retention at 100 min 64 +/- 3.2 vs. 50.2 +/- 3.6%, P < 0.005) and liquid (retention at 100 min 22.7 +/- 1.7 vs. 16.0 +/- 1.8%, P < 0.001) gastric emptying was slower in women than in men. Of all upper gastrointestinal symptoms (including nausea and vomiting), only abdominal bloating/fullness was associated with slower gastric emptying (P < 0.005). A multiple regression analysis demonstrated that both abdominal bloating/fullness and female sex were predictors of slower gastric emptying of both solids and liquids. CONCLUSIONS: We conclude that the presence of abdominal bloating/fullness but not any other upper gastrointestinal symptom is associated with diabetic gastroparesis and that gastric emptying is slower in diabetic women than in diabetic men.     

Increased prevalence of migraine in patients with uninvestigated dyspepsia referred for open-access upper gastrointestinal endoscopy

BACKGROUND AND STUDY AIMS: The association between gastrointestinal symptoms and headache is frequently unrecognized. The aim of the present study was to determine the prevalence of migraine in dyspeptic outpatients referred for upper gastrointestinal endoscopy. PATIENTS AND METHODS: Patients aged 18 - 55 years undergoing upper gastrointestinal endoscopy for dyspeptic symptoms in three endoscopic units were recruited consecutively. All of the patients were given a validated questionnaire on headache symptoms in order to determine the prevalence of migraine. Patients were divided into four groups (ulcer-like dyspepsia, reflux-like dyspepsia, dysmotility-like dyspepsia, only nausea and/or vomiting). Age-matched blood donors were given the same questionnaires and served as controls. RESULTS: A total of 378 patients (mean age 40 +/- 11, 52 % men) and 310 controls (mean age 39 +/- 11, 56 % men) were enrolled. No differences were observed between the two groups in the prevalence of migraine (15 % vs. 11 %; P = 0.12). A higher prevalence of migraine was found among women in both groups (P < 0.006). In patients with reflux-like and ulcer-like dyspepsia, the prevalence of migraine did not differ from that in the control individuals (8 % and 7 %, respectively), whereas a higher prevalence of migraine was noted in patients with dysmotility-like dyspepsia (23 %; P < 0.02 vs. controls, those with ulcer-like dyspepsia and those with reflux-like dyspepsia) and in patients with nausea and/or vomiting alone (53 %; P < 0.002 vs. all other groups). The multivariate analysis confirmed that the symptom pattern and sex were the only variables independently associated with migraine. CONCLUSIONS: A diagnosis of migraine should be considered in young patients referred for upper gastrointestinal endoscopy due to nausea and/or vomiting or for dysmotility-like dyspepsia.     

Colonoscopy first for iron-deficiency anaemia: a Numbers Needed to Investigate approach

BACKGROUND: British Society of Gastroenterology guidelines recommend that gastrointestinal investigations should be considered in males and post-menopausal women presenting with iron-deficiency anaemia (IDA). AIM: To compare the diagnostic yields and clinical effectiveness of upper and lower gastrointestinal (GI) investigation in detecting malignancy among patients presenting with IDA. DESIGN: Retrospective review of case notes, endoscopy records and radiology reports. METHODS: We reviewed the results of 3798 investigations in 2600 patients presenting to our hospital with IDA from October 1995 to December 2003. The findings of the 2318 gastroscopies were compared with those of the 896 colonoscopies and the 584 barium enemas. Patients diagnosed with GI malignancy were identified and their outcomes determined. RESULTS: Gastroscopy identified 44 patients with newly-diagnosed upper GI cancer (18 oesophageal, 26 gastric). Thus for patients being gastroscoped for IDA, the Numbers Needed to Investigate (NNI) to detect each cancer was 53. Five-year survival for these 44 patients was 10%, so the NNI to identify each curable upper GI malignancy was 527. Colonoscopy or barium enema identified 111 (7.5%) patients with newly diagnosed colorectal cancer, giving a NNI of 13. Their 5-year survival was 35%, giving a NNI to identify each curable colorectal cancer patient of 38. DISCUSSION: Potentially curable gastrointestinal malignancy was diagnosed over 13 times more commonly using colonoscopy or barium enema vs. gastroscopy. For patients presenting with IDA, our findings favour investigating the lower GI tract first, or performing both gastroscopy and colonoscopy during the same endoscopy list.     

Gastric Helicobacter and Upper Gastrointestinal Symptoms in Chronic Renal Failure

We studied histologically antral biopsies from 89 consecutive patients with chronic renal failure for Helicobacter pylori (previously Campylobacter pylori). A dose-response gastric secretion test was also performed. The frequency of Helicobacter-positive subjects was low (15/89, 17%), corresponding to figures reported in the literature for young symptomless volunteers. Helicobacter-positive patients had significantly more frequently upper gastrointestinal symptoms than Helicobacter-negative individuals (P < 0.05). Antral gastritis was more common in the Helicobacter-positive than in the Helicobacter-negatice renal patients (P < 0.01), but the incidence of body gastritis did not differ between them. The Helicobacter-positive patients had lower serum urea levels (P < 0.01) and higher acid outputs (P < 0.001) than Helicobacter-negative subjects. All patients had raised fasting serum gastrin levels, which possibly obscured the difference between Helicobacter-positive (283 pg/ml) and-negative (331 pg/ml) patients. We conclude that in chronic renal failure gastric colonization of Helicobacter pylori is not more frequent than usual. It correlates positively with antral gastritis, gastric acid output and upper gastrointestinal symptoms, but negatively with serum urea levels.     

A randomized controlled trial comparing the accuracy of general diagnostic upper gastrointestinal endoscopy performed by nurse or medical endoscopists

BACKGROUND AND STUDY AIMS: Rising demand for general diagnostic upper gastrointestinal endoscopy in the UK is outgrowing the capacity of doctors to provide this service within a reasonable time. One solution is to train nurses to carry out the procedure, but it is not known whether nurses can perform general diagnostic upper gastrointestinal endoscopy as competently as doctors. PATIENTS AND METHODS: A randomized controlled non-inferiority trial compared the adequacy and the accuracy of diagnostic upper gastrointestinal endoscopies performed by five medical and two nurse endoscopists. The videotaped procedures were assessed by a consultant gastroenterologist blinded to the identity of the endoscopist. RESULTS: 641 patients were randomly allocated (before attendance and consent procedure) to endoscopy carried out either by a doctor or a nurse. Of these, 412 were enrolled and 367 (89 %) were included in the analysis. An adequate view was obtained throughout in 53.4 % (93/177) of doctor endoscopies and 91.6 % (174/190) of nurse endoscopies (difference 38.2 %, 95 % CL 30.5 %, 47.2 %). In adequately viewed areas, the mean agreement between doctor and expert was 81.0 % and between nurse and expert it was 78.3 % (difference between the means 2.7 %, 95 % CL - 1.0 %, 6.4 %). There was no difference between doctors and nurses in the rate of biopsy performance (90.4 % and 91.1 %, respectively, P = 0.862). Nurses took longer (8.1 minutes vs. 4.6 minutes, P < 0.001) and used intravenous sedation more often (57.6 %, P = 0.027). Adequacy of view correlated positively with endoscopy duration ( P < 0.001), but diagnostic accuracy correlated inversely with duration ( P < 0.001). Neither adequacy or accuracy correlated significantly with use of intravenous sedation. CONCLUSIONS: In endoscopies performed by nurses, the proportion of adequate examinations was much higher than that found for doctors. In areas with an adequate view, there is no significant difference in accuracy between nurses and doctors. Nurses can provide an accurate general diagnostic upper gastrointestinal endoscopy service as competently as doctors.     

The outcome of suspected upper gastrointestinal bleeding with 24-hour access to upper gastrointestinal endoscopy: a prospective cohort study

BACKGROUND AND STUDY AIM: The aim was to evaluate the 30-day mortality after endoscopy for suspected upper gastrointestinal bleed, following the implementation of national audit guidelines at our hospital. PATIENTS AND METHODS: All patients with suspected upper gastrointestinal bleeding, referred for endoscopy to our teaching hospital between October 2001 and December 2003, were included in a prospective cohort study. RESULTS: A total of 716 patients with suspected upper gastrointestinal tract haemorrhage were referred for urgent endoscopy. The median age was 69 years (interquartile range 51 - 80 years). Bleeding from peptic ulcer remained the single most common endoscopic diagnosis (40 %). The overall re-bleeding rate for all patients with a gastrointestinal haemorrhage was 10 %. The overall 30-day mortality rate was 14.6 %. This was not significantly different from the mortality rate in 1995 of 10.5 % ( P = 0.11). Patients who died were significantly older (78 vs. 67 years, 95 %CI of the difference 5 to 12, P < 0.001). However, in only 29 % (30/105) was gastrointestinal haemorrhage stated in the death certificate as a factor which contributed to their death. CONCLUSIONS: Our results show that implementing the good practice guideline has a limited impact on overall mortality because of contributing factors that are beyond the control of clinicians.     

两种不同重量及大小的胶囊内镜之间胃肠通过时间及全小肠检查完成率的对比*

目的探究两种不同重量及大小的胶囊内镜之间胃通过时间(GTT)、小肠通过时间(SBTT)及全小肠检查完成率(CR)是否不同。方法回顾性纳入因各种原因而接受了OMOM胶囊内镜检查或Miro Cam胶囊内镜检查(比OMOM胶囊更小且更轻)的患者,对比分析了这两种不同重量及大小的胶囊内镜的GTT、SBTT以及CR。结果共纳入1 448名符合条件的患者,其中OMOM组628例,Miro Cam组820例。总体上,在工作时间校正后SBTT和CR方面,两组之间差异无统计学意义(P0.05)。在克罗恩病或可疑克罗恩病患者中,OMOM组的GTT明显长于Miro Cam组[(53.4±52.6)min比(41.1±47.9)min,P=0.022)];在消化道出血患者中,OMOM组的GTT明显短于Miro Cam组[(42.1±44.8)min比(62.0±78.6)min,P=0.016]。结论总体来说,两种不同重量及大小的胶囊内镜之间的GTT、SBTT及CR没有明显差别,但在克罗恩病或可疑克罗恩病患者中,更轻且更小的胶囊内镜的GTT较短;而在消化道出血患者中,更轻且更小的胶囊内镜的GTT较慢。     

Gastric Helicobacter and upper gastrointestinal symptoms in chronic renal failure

We studied histologically antral biopsies from 89 consecutive patients with chronic renal failure for Helicobacter pylori (previously Campylobacter pylori). A dose-response gastric secretion test was also performed. The frequency of Helicobacter-positive subjects was low (15/89, 17%), corresponding to figures reported in the literature for young symptomless volunteers. Helicobacter-positive patients had significantly more frequently upper gastrointestinal symptoms than Helicobacter-negative individuals (P less than 0.05). Antral gastritis was more common in the Helicobacter-positive than in the Helicobacter-negative renal patients (P less than 0.01), but the incidence of body gastritis did not differ between them. The Helicobacter-positive patients had lower serum urea levels (P less than 0.01) and higher acid outputs (P less than 0.001) than Helicobacter-negative subjects. All patients had raised fasting serum gastrin levels, which possibly obscured the difference between Helicobacter-positive (283 pg/ml) and -negative (331 pg/ml) patients. We conclude that in chronic renal failure gastric colonization of Helicobacter pylori is not more frequent than usual. It correlates positively with antral gastritis, gastric acid output and upper gastrointestinal symptoms, but negatively with serum urea levels.     

High-risk ED patients with nonvariceal upper gastrointestinal hemorrhage undergoing emergency or urgent endoscopy: a retrospective analysis

OBJECTIVES: The optimal timing of interventional endoscopy within the initial 24 hours remains controversial. We designed a retrospective study to compare the outcomes between emergency endoscopy (EE) and urgent endoscopy (UE) for high-risk patients with nonvariceal upper gastrointestinal hemorrhage presenting to the emergency department (ED). METHODS: The medical records of 189 patients with nonvariceal upper gastrointestinal hemorrhage who underwent endoscopy within 24 hours of admission to the ED were reviewed. Patients were divided into 2 groups: EE group (<8 hours) or UE group (8-24 hours). We compared the endoscopic findings, hemostatic procedures, rate of hemostasis, rebleeding, need for transfusion, length of hospitalization, and mortality between the 2 groups. RESULTS: There were 88 patients (47%) in the EE group and 101 patients (53%) in the UE group. Ulcers with active bleeding or exposed vessel were found more frequently in the EE group than in the UE group (19% vs 8%, P = .03; 34% vs 12%, P < .001). Fifty patients had blood retention in the stomach, especially in the EE group (40% vs 15%, P < .001). Forty-four (50%) patients in the EE group and 21 (21%) patients in the UE group received endoscopic interventions. Combination modalities of endoscopic hemostasis were more commonly used in the EE group than in the UE group (40% vs 15%, P < .001). Primary hemostasis was achieved at a rate of 95% in both groups. There was no statistical difference regarding the rate of recurrent bleeding, total amount of transfusion, length of hospital stay, and mortality rate in both groups. CONCLUSIONS: Although more active lesions were detected and more therapeutic attempts were performed in the EE group, the outcome showed no difference in both groups. Emergency endoscopy performed less than 8 hours after arrival to the ED showed no definite benefit in comparison with UE performed within 8 to 24 hours.     

A comparison of the palliative care needs of patients dying from chronic respiratory diseases and lung cancer

This paper reports on data from the Regional Study of Care for the Dying, conducted in 1990, and compares symptoms, care and service utilization for patients with chronic lung diseases (CLD) and lung cancer (LC) in the final 12 months of life. Post-bereavement structured interviews were conducted with informal carers of 449 LC patients and 87 CLD patients. The LC patients were significantly younger than those with CLD (P = 0.001) and these respondents were more likely to have been a spouse (P = 0.034). No differences were found in the mean number of symptoms reported by the two groups in the final year or week of life, although the CLD patients were more likely to have experienced these symptoms for longer. Significantly more patients with CLD than LC experienced breathlessness in the final year (94% CLD vs 78% LC, P < 0.001) and final week (91% CLD vs 69% LC, P < 0.001) of life. Significantly more LC patients were reported to have experienced anorexia (76% LC vs 67% CLD, P = 0.06) and constipation (59% LC vs 44% CLD, p = 0.01) in the final year of life. There were no differences in general practitioner use, but LC patients were reported to have received more help from district nurses (52% LC vs 39% CLD, P = 0.025) and from a palliative care nurse (29% LC vs 0% CLD, P < 0.001). More CLD patients were reported to have received help from social services (29% CLD vs 18% LC, P = 0.037). LC patients were reported to be more likely to have known they might die (76% LC vs 62% CLD, P = 0.003) and to have been told this by a hospital doctor (30% LC vs 8% CLD, P = 0.001). Among those that knew, LC patients were told earlier prior to death than CLD patients. This study suggests that patients with CLD at the end of life have physical and psychosocial needs at least as severe as patients with lung cancer.     

Impact of open-access endoscopy on detection of early oesophageal and gastric cancer 1994 - 2003: population-based study

BACKGROUND AND STUDY AIMS: There is conflicting evidence regarding the ability of open-access endoscopy to detect oesophageal and gastric cancers at an earlier stage. The aim of the study was to assess the impact, with regard to earlier diagnosis of oesophageal and gastric cancer, of the first 10 years of a regional open-access endoscopy service in the Dumfries and Galloway region of Scotland. PATIENTS AND METHODS: Data were retrieved from prospectively compiled endoscopy and cancer registry databases. Route of referral (open-access vs. outpatient vs. inpatient), presenting symptoms (alarm vs. benign) and UICC disease stage in consecutive 5-year periods (1994 - 1998 and 1999 - 2003) were compared. RESULTS: 386 oesophagogastric cancers were identified (179 during 1994 - 1998 and 207 in 1999 - 2003). The number of patients undergoing endoscopy increased from 500 per annum prior to the open-access service to 7359 during 1994 - 1998 and 9701 in 1999 - 2003. Patient age, route of referral and presenting symptoms were unchanged. There was no improvement in disease stage at diagnosis (stage I, 7 % vs. 7 %; stage II, 16 % vs. 17 %; stage III, 31 % vs. 28 %). CONCLUSIONS: Despite a 32 % increase in endoscopy workload, the provision, over 10 years, of a regional open-access endoscopy service was not associated with earlier detection of oesophageal or gastric cancer.     

早期内镜诊治应用于老年急性非静脉曲张性上消化道大出血患者的价值分析

目的探讨早期内镜在老年急性非静脉曲张性上消化道大出血(ANVUGIB)患者的诊断和治疗中的价值。方法回顾分析该院2015年1月-2015年9月150例老年ANVUGIB的患者早期内镜和择期内镜的诊疗结果,分析上消化道大出血的原因,比较两组患者在内镜病因检出率、首次出血止血成功率、再出血率、外科手术率、平均止血时间、输血量、平均住院时间和平均住院费用的差别。采用诺丁汉健康调查问卷(NHP)比较两组患者出院3个月后生活质量的差别。结果老年ANVUGIB出血患者中,消化性溃疡、胃癌和急性糜烂出血性胃炎是最常见的出血原因。与择期内镜组相比,早期内镜组病因检出率、首次出血止血成功率明显增高(P0.05),再出血率、外科手术率明显降低,患者输血量减少,平均住院时间缩短,平均住院费用降低(P0.05),两组差异有统计学意义,早期内镜组患者出院3个月后生活质量明显高于择期内镜组患者(P0.05)。结论老年ANVUGIB患者进行早期内镜检查及治疗安全,效果确切,能尽快明确出血原因,减少患者住院费用,值得推广。     

Continuity of care and cancer screening among health plan enrollees

CONTEXT: Although having a usual source of care has been associated with cancer screening, whether there is additional benefit from continuity with a specific physician is uncertain. In addition, little is known about the relationship between continuity of care and receipt of colorectal and prostate cancer screening. METHODS: Subjects were enrolled in a Washington State health plan that operates an integrated delivery system that emphasizes access to primary care. Among patients age 50-78 years old with 2 or more primary care visits in 2002-2003 (N = 67,633), we determined whether higher continuity (>/=50% of visits with the most visited primary care provider) was associated with colorectal, breast, and prostate cancer screening. Random-effects logistic regression estimated adjusted percentages of patients who received fecal occult blood testing, lower endoscopy (sigmoidoscopy or colonoscopy), screening mammography, and prostate specific antigen (PSA) testing. RESULTS: Patients with higher continuity were more likely to receive fecal occult blood testing than patients with lower continuity (28.9% vs. 26.8%; P < 0.001) but less likely to receive lower endoscopy (12.9% vs. 14.3%; P < 0.001). Although higher continuity was not significantly associated with screening mammography (P = 0.38), men with higher continuity were more likely to receive PSA testing than men with lower continuity (39.4% vs. 37.4%; P = 0.008). CONCLUSIONS: In an insured population with a high degree of primary care access, continuity with a specific primary care physician was associated with the selection of less invasive colorectal cancer screening tests by patients and physicians and greater likelihood of PSA testing.     

急诊内镜检查在上消化道出血中的应用

目的探讨急诊内镜检查在上消化道出血患者中的临床应用价值。方法回顾性分析2003年10月至2007年5月因上消化道出血于48h内行急诊内镜检查159例患者的临床资料，对比分析不同时间内镜检查的差异以及检查前冰盐水洗胃与否对检查结果的影响。结果急诊内镜检查确诊率为94．97％，不同时间内镜检查确诊率不同，发生出血后24h内行内镜检查其确诊率明显提高，与24～48h相比差异有显著性（P〈0．01）。内镜检查前洗胃与否两组对比分析无明显差异（P〉0．05），所有患者均未发生严重并发症。结论急诊内镜检查是安全有效的，尽早行内镜检查可提高诊断准确率，内镜检查前无需冰盐水洗胃。     

Overlooked lesions at emergency endoscopy for acute nonvariceal upper gastrointestinal bleeding

BACKGROUND AND STUDY AIMS: Excessive blood covering the examination field is a frequent cause of diagnostic failure in emergency endoscopy for acute upper gastrointestinal bleeding. The implications and outcome in these patients have not been well described. PATIENTS AND METHODS: The records for 1459 consecutive patients who presented at our medical center with acute nonvariceal upper gastrointestinal bleeding during a 15-month period were reviewed. All of the patients underwent emergency endoscopy within 24 h of initial presentation. Patients in whom an identifiable bleeding source was not found in spite of an overtly bloody lumen were designated as having a failure of diagnosis, and these cases were analyzed further. RESULTS: Diagnosis failed in 25 patients (1.7 %), 16 of whom underwent repeat endoscopy or surgical intervention. Bleeding vessels were identified in 13 of these patients. Gastric and duodenal ulcers were the most commonly overlooked lesions, with locations in the cardia (n = 3), fundus (n = 2), posterior wall of the antrum (n = 1), duodenal bulb (n = 3), second part of the duodenum (n = 2), and in the stoma of a Billroth II gastrectomy (n = 2). The rates for endoscopic complications, recurrent bleeding, surgery, and mortality were significantly higher in the group with diagnostic failure than in patients with acute upper gastrointestinal bleeding in whom diagnosis did not fail (8 % vs. 0.4 %; 20 % vs. 3.1 %; 16 % vs. 2.9 %; and 20 % vs. 3.6 %, respectively). CONCLUSIONS: In acute nonvariceal upper gastrointestinal bleeding, diagnostic failure is associated with higher morbidity and mortality. The data from this study emphasize the importance of good preparation before the procedure and adequate removal of blood during emergency endoscopy procedures.     

Hereditary hemorrhagic telangiectasia: clinical features in ENG and ALK1 mutation carriers

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is a genetic disorder characterized by epistaxis, mucocutaneous telangiectases and visceral arteriovenous malformations (AVMs), particularly in the brain (CAVMs), lungs (PAVMs), liver (HAVMs) and gastrointestinal tract (GI). The identification of a mutated ENG (HHT1) or ALK-1 (HHT2) gene now enables a genotype-phenotype correlation. OBJECTIVE: To determine the incidence of visceral localizations and evaluate phenotypic differences between ENG and ALK1 mutation carriers. METHODS: A total of 135 consecutive adult patients were subjected to mutational screening in ENG and ALK1 genes and instrumental tests to detect AVMs, such as chest-abdomen multislice computed tomography (MDCT), brain magnetic resonance imaging and magnetic resonance angiography (MRI/MRA), upper endoscopy, were offered to all patients, independent of presence of clinical symptoms. The 122 patients with identified mutations were enrolled in the study and genotype-phenotype correlations were established. RESULTS: PAVMs and CAVMs were significantly more frequent in HHT1 (75% vs. 44%, P < 0.0005; 20% vs. 0%, P < 0.002, respectively) and HAVMs in HHT2 (60% vs. 84%, P < 0.01). No age difference was found for PAVMs whereas HAVMs were significantly higher in older patients in both HHT1 and HHT2. Neurological manifestations secondary to CAVMs/PAVMs were found only in HHT1 patients, whereas severe liver involvement was detected only in HHT2. Respiratory symptoms were mainly detected in HHT1. CONCLUSIONS: Our study evidences a higher visceral involvement in HHT1 and HHT2 compared with previous reports. HHT1 is more frequently associated with congenital AVM malformations, such as CAVMs and PAVMs whereas HHT2 predominantly involves the liver. The ENG gene should be first targeted for mutational screening in the presence of large PAVM in patients < 45 years.     

胃早癌患者内镜下黏膜剥离术后二次内镜检查的临床影响

目的评价二次内镜是否能够预防内镜下黏膜剥离术(ESD)伴迟发性出血及确定何种病变需要二次内镜检查。方法共纳入2014年10月-2016年9月经组织学诊断的胃早癌患者98例,ESD术后24 h出现黏膜破损相关性出血认为是迟发性出血。回顾性研究患者病变及手术相关因素,行二次内镜检查前后的出血率。结果 98例患者整块切除率为100.0%,所有病灶切缘为阴性,无消化道穿孔及死亡严重并发症发生。ESD术后迟发性出血发生率5.1%(5/98),均已在二次内镜下成功止血,无1例手术、迟发性出血阴性者,随访无再出血发生。40.0%迟发性出血者(2/5)给予输血。ESD术后二次内镜检查的时间中位数是术后第2天(1~3 d),5例ESD术后迟发性出血患者出血时间中位数是术后第1天(1~10 d),手术持续时间中位数是75 min(60~150 min),预测成功率94.9%。单因素分析结果表明;年龄[(69.6±7.9)vs(60.9±10.1)岁,P=0.003],手术时间[(90.0±41.0)vs(66.0±42.0)min,P=0.000]是迟发性出血组和无出血组的2个危险因素。二元Logistic回归分析显示:手术时间(OR=1.07,95%CI:0.73~14.63,P=0.010)是ESD迟发性出血唯一预测因素。结论二次内镜检查预防胃ESD术后迟发性出血可能有效,尤其在ESD术后48 h内,操作时间是胃ESD术后迟发性出血的独立危险因素。     

Prevalence of delayed gastric emptying in diabetic patients and relationship to dyspeptic symptoms: a prospective study in unselected diabetic patients

OBJECTIVE: Data on the prevalence of abnormal gastric emptying in diabetic patients are still lacking. The relation between gastric emptying and dyspeptic symptoms assessed during gastric emptying measurement has not yet been investigated. The aim was to investigate the prevalence of delayed gastric emptying in a large cohort of unselected diabetic patients and to investigate the relation between gastric emptying and gastrointestinal sensations experienced in the 2 weeks before and during the test meal, prospectively. RESEARCH DESIGN AND METHODS: Gastric emptying was evaluated in 186 patients (106 with type 1 diabetes, mean duration of diabetes 11.6 +/- 11.3 years) using 100 mg (13)C-enriched octanoic acid added to a solid meal. RESULTS: Gastric emptying was significantly slower in the diabetic subjects than in the healthy volunteers (T(50): 99.5 +/- 35.4 vs. 76.8 +/- 21.4 min, P < 0.003; Ret(120 min): 30.6 +/- 17.2 vs. 20.4 +/- 9.7%, P < 0.006). Delayed gastric emptying was observed in 51 (28%) diabetic subjects. The sensations experienced in the 2 weeks before the test were weakly correlated with the sensation scored during the gastric emptying test. Sensations assessed during the gastric emptying test did predict gastric emptying to some extent (r = 0.46, P < 0.0001), whereas sensations experienced in the previous 2 weeks did not. CONCLUSIONS: This prospective study shows that delayed gastric emptying can be observed in 28% of unselected patients with diabetes. Upper gastrointestinal sensations scored during the gastric emptying tests do predict the rate of gastric emptying to some extent and sensation experienced during daily life does not.     

The treatment of diabetic gastroparesis with botulinum toxin injection of the pylorus

OBJECTIVE: Gastroparesis is a disorder of delayed gastric emptying that is often chronic in nature. Up to 50% of type 1 diabetic subjects have symptoms of gastroparesis, which include nausea, vomiting, and early satiety. Elevated pyloric pressures may be responsible for delayed gastric emptying in diabetic subjects. Botulinum toxin inhibits the release of acetylcholine and produces transient paralysis when injected into smooth muscle. The aim of this study was to determine whether injection of the pylorus with botulinum toxin in patients with diabetic gastroparesis improves symptoms of gastroparesis, alters gastric emptying scan time, and/or changes weight and insulin use. RESEARCH DESIGN AND METHODS: This was an open-label trial with age- and sex-matched control subjects from a tertiary care referral center for patients with gastroparesis. Eight type 1 diabetic subjects (six women and two men; mean age 41 years; mean years with diabetes 25.3) who had failed standard therapy were enrolled. Intervention consisted of injection of the pylorus with 200 units of botulinum toxin during upper endoscopy. Symptoms, antropyloric manometry, gastric emptying scan times, weight, and insulin use were all recorded before intervention and during a 12-week follow-up period. RESULTS: Seven of the eight patients completed the full 12-week follow-up period. No complications were noted. Mean symptom scores declined from 27 to 12.1 (P < 0.01), whereas the SF-36 physical functioning domain also improved (P < 0.05). Four patients noted an increase in insulin use of >5 units/day. Six of the seven patients gained weight (P = 0.05). Gastric emptying scan time improved in four patients. CONCLUSIONS: Botulinum toxin injection of the pylorus is safe and improves symptoms in patients with diabetic gastroparesis. These results warrant further investigation with a large, double-blind, placebo-controlled trial.
