Optimization of the emergency endoscopy process for patients with esophagogastric variceal bleeding using failure mode and effect analysis.

OBJECTIVE: To optimize the emergency endoscopy process for patients with esophagogastric variceal bleeding (EGVB) using failure mode and effect analysis (FMEA). METHOD: In this retrospective analysis, we enrolled patients who were hospitalized in Ganzhou People's Hospital from January 2021 to December 2021. They were divided into 51 cases before and 51 cases after the intervention according to the time of FMEA model intervention. The risk of unsafe transport, endoscopic hemostasis success rate, RPN (risk priority number) value, dual venous access time, resuscitation success rate, emergency endoscopy timeout execution rate, patient health education awareness rate, and endoscopic ligation of esophageal varices (EVL) procedure volume were compared accordingly before and after the procedure. RESULTS: After the FMEA intervention, the emergency endoscopy process for EGVB patients was optimized, the risk of unsafe transport for emergency EGVB endoscopy was reduced, and the success rate of emergency endoscopic hemostasis for patients was improved. Also, the failure mode of RPN values greater than 12 was improved. After the countermeasures were implemented, the resuscitation success rate of EGVB patients reached 95%, the safe transport pass rate increased from 88% to 98.7%, and the patient health education awareness increased from 69% to 92%. The number of EGVB patients who underwent EVL surgery ranked second in the province. The waiting time, gastric function recovery time, dual venous access time, and hospital stay of patients who underwent the optimized procedure were significantly shorter compared to those before implementation (all P<0.01). The incidence of adverse events was significantly lower in patients who underwent the optimized procedure compared to the pre-implementation period (P<0.01). CONCLUSION: Applying FMEA to analyze and optimize the process of EGVB patients undergoing emergency endoscopy can maximize patient life safety and treatment safety, as well as improve medical quality and care safety.

Emergency Endoscopic Hemostasis for Gastrointestinal Bleeding Using a Self-Assembling Peptide: A Case Series.

Background and Objectives: A novel synthetic self-assembling peptide, PuraStat, has been introduced as a hemostatic agent. This case series aimed to evaluate the clinical efficacy of PuraStat for gastrointestinal bleeding during emergency endoscopy. Cases: Twenty-five patients with gastrointestinal bleeding who had undergone emergency endoscopy with PuraStat between August 2021 and December 2022 were retrospectively examined. Six patients were receiving antithrombotic agents, and ten patients with refractory gastrointestinal bleeding had undergone at least one endoscopic hemostatic procedure. The breakdown of bleeding was gastroduodenal ulcer/erosion in 12 cases, bleeding after gastroduodenal or colorectal endoscopic resection in 4 cases, rectal ulcer in 2 cases, postoperative anastomotic ulcer in 2 cases, and gastric cancer, diffuse antral vascular ectasia, small intestinal ulcer, colonic diverticular bleeding, and radiation proctitis in each case. The method of hemostasis was only PuraStat application in six cases, and hemostasis in combination with high-frequency hemostatic forceps, hemostatic clip, argon plasma coagulation, and hemostatic agents (i.e., thrombin) in the remaining cases. Rebleeding was observed in three cases. Hemostatic efficiency was observed in 23 cases (92%). Conclusions: PuraStat has the expected hemostatic effect on gastrointestinal bleeding during emergency endoscopy. The use of PuraStat should be considered in emergency endoscopic hemostasis of gastrointestinal bleeding.

Evaluation of a novel disposable esophagogastroduodenoscopy system in emergency, bedside, and intraoperative settings: Pilot study (with videos).

OBJECTIVES: The disposable esophagogastroduodenoscopy (EGD) system is a novel endoscopic device which is highly portable and is designed to eliminate the risk of cross-infection caused by reusable EGD. This study aimed to investigate the feasibility and safety of disposable EGD in emergency, bedside, and intraoperative settings. METHODS: This was a prospective, single-center, noncomparative study. Disposable EGD was used for emergency, bedside, and intraoperative endoscopies in 30 patients. The primary end-point was the technical success rate of the disposable EGD. Secondary end-points included technical performance indicators including clinical operability, image quality score, procedure time, the incidence of device malfunction and/or failure, and the incidence of adverse events. RESULTS: A total of 30 patients underwent diagnosis and/or treatment with disposable EGD. Therapeutic EGD was performed on 13/30 patients, including hemostasis (n = 3), foreign body retrieval (n = 6), nasoenteric tube placement (n = 3), and percutaneous endoscopic gastrostomy (n = 1). The technical success rate was 100%: all procedures and indicated interventions were completed without changing to a conventional upper endoscope. The mean image quality score obtained immediately after procedure completion was 3.72 ± 0.56. The mean (± SD) procedure time was 7.4 (± 7.6) min. There were no device malfunctions or failures, device-related adverse events, or overall adverse events. CONCLUSION: The disposable EGD may be a feasible alternative to the traditional EGD in emergency, bedside, and intraoperative settings. Preliminary data show that it is a safe and effective tool for diagnosis and treatment in emergency and bedside upper gastrointestinal cases.

Safety and Efficacy of Sedation During Emergency Endoscopy for Upper Gastrointestinal Bleeding: A Propensity Score Matching Analysis.

BACKGROUND AND AIM: This study aimed to compare patients with and without sedation during emergency endoscopy for upper gastrointestinal bleeding (UGIB) and to clarify the safety and efficacy of sedation in emergency endoscopy. METHODS: We retrospectively collected 389 patients who underwent emergency endoscopy for UGIB at Ureshino Medical Center from 2016 to 2021. Patients were divided into two groups: sedation group during emergency endoscopy and nonsedation group. Clinical characteristics, patient status on admission, and UGIB etiology were evaluated. Treatment outcomes and adverse events were evaluated using propensity score matching (PSM), and risk factors for mortality from UGIB were investigated using Cox multivariate analysis. RESULTS: The sedation group was significantly younger, composed of a higher proportion of males, and had chronic liver disease. Blood pressure and hemoglobin level on admission were significantly higher in the sedation group. The main cause of bleeding was peptic ulcer, which was significantly higher in the nonsedation group. PSM created 133 matched pairs. The success rate of endoscopic hemostasis was similar in both groups, and procedure time was significantly shorter in the sedation group than in the nonsedation group (17.6 ± 10.0 versus 20.2 ± 10.2 min, P = 0.04). There were no significant differences in adverse events between groups. Cox multivariate analyses revealed that red blood cell transfusion [hazard ratio (HR) 4.45, P < 0.02] and rebleeding (HR 3.30, P = 0.03) were associated with increased risk of 30-day mortality from UGIB. CONCLUSIONS: Sedation reduced the procedure time during emergency endoscopy for UGIB. Sedation during emergency endoscopy for UGIB is acceptable for safe endoscopic procedures.

Risk factors for emergency endoscopic variceal ligation treatment failure of acute variceal bleeding.

OBJECTIVE: To determine the risk factors for emergency endoscopic variceal ligation (EVL) failure in acute variceal bleeding (AVB). METHODS: Data from 161 cirrhosis patients with oesophageal variceal bleeding who underwent emergency EVL treatment at the Second Hospital of Hebei Medical University from January 2018 to May 2021 were retrospectively analysed. Enrolled patients were divided into a successful treatment group and a failed treatment group. The variables studied were demographic, clinical, imaging, laboratory, and endoscopic data from the enrolled patients. RESULTS: Of the enrolled patients, 19 patients experienced emergency EVL failure. Of these patients, nine underwent emergency endoscopic treatment again, six patients were treated with a Sengstaken-Blakemore tube for haemostasis and endoscopic treatment, four patients received drug therapy. The presence of portal vein thrombosis (PVT) in the failure group was higher than that in the success group (p < .05). Active bleeding on endoscopy was associated with emergency EVL failure for patients with Child-Pugh class C (p < .05). CONCLUSIONS: Child-Pugh class C with active bleeding on endoscopy or the presence of PVT could increase the risk of emergency EVL failure. The patient's condition should be fully evaluated before emergency endoscopic treatment to reduce the risk of failure.

Treatment Strategies in Emergency Endoscopy for Acute Esophageal Variceal Bleeding (CHESS1905): A Nationwide Cohort Study.

Background and Aims: Emergency endoscopy is recommended for patients with acute esophageal variceal bleeding (EVB) and their prognosis has improved markedly over past decades due to the increased specialization of endoscopic practice. The study aimed to compare outcomes following emergency endoscopic injection sclerotherapy (EIS) and endoscopic variceal ligation (EVL) in cirrhotic patients with acute EVB. Methods: Cirrhotic patients with acute EVB who underwent emergency endoscopy were retrospectively enrolled from 2013 to 2020 across 34 university hospitals from 30 cities. The primary outcome was the incidence of 5-day rebleeding after emergency endoscopy. Subgroup analysis was stratified by Child-Pugh class and bleeding history. A 1:1 propensity score matching (PSM) analysis was performed. Results: A total of 1,017 and 382 patients were included in EIS group and EVL group, respectively. The 5-day rebleeding incidence was similar between EIS group and EVL group (4% vs. 5%, P = 0.45). The result remained the same after PSM (P = 1.00). Among Child-Pugh class A, B and C patients, there were no differences in the 5-day rebleeding incidence between the two groups after PSM (P = 0.25, 0.82, and 0.21, respectively). As for the patients with or without bleeding history, the differences between EIS group and EVL group were not significant after PSM (P = 1.00 and 0.26, respectively). Conclusion: The nationwide cohort study indicates that EIS and EVL are both efficient emergency endoscopic treatment strategies for acute EVB. EIS should not be dismissed as an economical and effective emergency endoscopic treatment strategy of acute EVB. ClincialTrials.gov number NCT04307264.

Changes in the Proportion of Gastrointestinal Emergency Endoscopy and Peptic Ulcer Disease During the COVID-19 Pandemic: A Local Retrospective Observational Study From Vietnam.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has disrupted the practice of gastrointestinal (GI) endoscopy units and may increase the risk of digestive disorders. We described the situational changes in GI endoscopy and peptic ulcer disease (PUD) proportion during COVID-19 in Vietnam and examined the associated factors. METHODS: A retrospective ecological study was conducted on data of Hanoi Medical University Hospital, Vietnam. The number of upper GI endoscopy and the proportion of GI emergency endoscopy and PUD were compared between 2019 and 2020 by month (January to June). Log-binomial regression was used to explore associated factors of GI emergency endoscopy and PUD. RESULTS: The number of endoscopies decreased remarkably during the nationwide social distancing in April 2020. Compared to April 2019, the proportion in April 2020 of both GI emergency endoscopy [4.1 vs. 9.8%, proportion ratio (PR) 2.39, 95% CI 2, 2.87], and PUD [13.9 vs. 15.8%; PR, 1.14; 95% CI, 1.01, 1.29] was significantly higher. In log-binomial models, the proportion of GI emergency endoscopy was higher in April 2020 compared to April 2019 (adjusted PR, 2.41; 95% CI, 2.01, 2.88). Male sex and age of ≥50 years were associated with an increased PUD and GI emergency conditions. CONCLUSION: The proportion of both GI emergency endoscopy and PUD was significantly higher during the time of the state of emergency due to the ongoing COVID-19 pandemic in 2020 when compared to 2019 at the same health facility in Vietnam. The findings suggest that healthcare delivery reforms during the era of an emerging pandemic are required to reduce digestive disorders, in particular, and chronic diseases in general.

Changes in endoscopic patterns before and during COVID-19 outbreak: Experience at a single tertiary center in Korean.

BACKGROUND: The surge of coronavirus disease 2019 (COVID-19) patients has markedly influenced the treatment policies of tertiary hospitals because of the need to protect medical staff and contain viral transmission, but the impact COVID-19 had on emergency gastrointestinal endoscopies has not been determined. AIM: To compare endoscopic activities and analyze the clinical outcomes of emergency endoscopies performed before and during the COVID-19 outbreak in Daegu, the worst-hit region in South Korea. METHODS: This retrospective cohort study was conducted on patients aged ≥ 18 years that underwent endoscopy from February 18 to March 28, 2020, at a tertiary hospital in Daegu. Demographics, laboratory findings, types and causes of emergency endoscopies, and endoscopic reports were reviewed and compared with those obtained for the same period in 2018 and 2019. RESULTS: From February 18 to March 28, a total of 366 emergent endoscopic procedures were performed: Upper endoscopy (170, 50.6%), endoscopic retrograde cholangiopancreatography (113, 33.6%), and colonoscopy with sigmoidoscopy (53, 15.8%). The numbers of procedures performed in 2018 and 2019 dropped by 48.8% and 54.8%, respectively, compared with those in 2020. During the COVID-19 outbreak, the main indications for endoscopy were melena (36.7%), hematemesis (30.6%), and hematochezia (10.2%). Of the endoscopic abnormalities detected, gastrointestinal bleeding was the most common: 39 cases in 2018, 51 in 2019, and 35 in 2020. CONCLUSION: The impact of COVID-19 is substantial and caused dramatic reductions in endoscopic procedures and changes in patient behaviors. Long-term follow-up studies are required to determine the effects of COVID-19 induced changes in the endoscopy field.

Emergency upper gastrointestinal endoscopy performed safely in a patient with COVID-19 with suspected hemorrhagic shock.

Coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 has spread explosively throughout the world and has since been declared a pandemic by the World Health Organization. Although it is recommended that upper gastrointestinal endoscopies either be postponed or canceled during the pandemic because of their high risk of aerosol generation, this does not apply in emergency cases, which may include patients with coronavirus disease. In this case report, we describe the safe undertaking of an emergency upper gastrointestinal endoscopy in a patient with suspected hemorrhagic shock who tested positive for the severe acute respiratory syndrome coronavirus 2 using the polymerase chain reaction. We performed the procedure in the contamination zone of a specialized coronavirus disease ward with prespecified zones. Full personal protective equipment was worn during the procedure, as recommended by various academic societies, and careful attention was paid to the sterilization of all equipment after the procedure. Thus, emergency endoscopies can be performed safely in patients with coronavirus disease in a suitable environment by using appropriate personal protective equipment and by handling the equipment appropriately.

Hemospray® during Emergency Endoscopy: Indonesia's First Experience from 37 Patients.

Gastrointestinal bleeding (GIB) is one of the main indications for performing endoscopy; this condition can be life threatening. In some cases, emergency endoscopy (EE) is necessary to identify the source and stop the bleeding. Recently, hemostatic powder was introduced, one of which was Hemospray® (Cook Medical, Winston-Salem, NC, USA), which showed promising results for rapid hemostasis in primary treatment and salvage when conventional methods fails. Samples were taken retrospectively for a duration of 3 years since Hemospray was first introduced in Indonesia, from January 2016 to January 2019. The total number of EEs that used Hemospray were 37 procedures for 37 patients; 21 (56.8%) were males and 16 (43.2%) were females, while the average age was 67.8 years. Hemospray was used for upper GIB in 30 cases (81.1%) and for lower GIB in 7 (18.9%). Hemospray was used as monotherapy for 24 patients (64.9%) and as secondary modality for 13 (35.1%). The primary treatment was argon plasma coagulation in 8 cases (21.6%), adrenaline in 4 (10.8%), and Histoacryl® in 1 (2.7%). The mortality rate was 37.8% (n = 14); most deaths occurred within 30 days after the EE was performed, and none of the deaths was related to endoscopy or GIB. Hemospray was able to achieve hemostasis in all cases. Furthermore, there was no event of rebleeding. When conventional modalities alone were inadequate, the combination with Hemospray appeared to be able to control the bleeding. One of the main advantages of Hemospray is the ease in reaching difficult areas, and it require less skill compared to conventional modalities.

A Statistically Significant Reduction in Length of Stay and Hospital Costs with Equivalent Quality of Care Metrics for ERCPs Performed During the Weekend Versus Postponed to Weekdays: A 6-Year Study of 533 ERCPs at Four Teaching Hospitals.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a diagnostic/therapeutic endoscopic procedure for numerous pancreaticobiliary diseases. Data regarding performing ERCP on weekend (WE; Saturday/Sunday) versus postponing ERCP to first two available weekdays (WD; Monday/Tuesday) are scarce. ERCP requires costly resources including specialized nurses, endoscopy room equipped with fluoroscopy, anesthesia services, and highly trained therapeutic endoscopists. Hospitals frequently do not have these resources readily available during WE, leading to postponing ERCPs to WD. AIMS: This study analyzes the effect of performing ERCP on WE versus postponement to WD on hospital efficiency, and on patient safety/outcomes. METHODS: A computerized search of electronic medical records, January 2011-December 2016, at four Beaumont Hospitals retrospectively identified all gastroenterology consults performed on Friday or Saturday before 12:00 noon, which resulted in ERCP performed for any indication on WE versus postponing ERCP to WD. Length of stay (LOS), hospital costs, hospital charges, and hospital reimbursements were compared between both groups, as were quality of care measures. RESULTS: Among 5196 patients undergoing ERCPs, 533 patients were identified, including 315 patients in the WE group and 218 patients in the WD group. Comparing WE versus WD groups, median LOS was shorter (4.5 days vs. 6.9 days, p < 0.0001); median hospital costs were less ($9208 vs. $11,657, p < 0.0001); and median hospital charges were less ($28,026 vs. $37,899, p < 0.0001). Median hospital reimbursements were not significantly different in WE versus WD groups ($10,277 vs. $10,362, p = 0.65). Median hospital charges were lower than median hospital reimbursements (net profit) in WE but not in WD. WE versus WD had no significant differences in morbidity, mortality, ≤ 30-day readmission rates, need for repeat ERCP ≤ 30 days, or post-ERCP complications. LIMITATIONS: This is a retrospective study. CONCLUSIONS: Performing ERCPs during weekends significantly reduced LOS, hospital costs, and hospital charges compared to postponing ERCP to WD and resulted in net hospital profits, without impairing quality of medical care.

Primary application of disposable portable gastroscopy in emergency upper gastrointestinal examination / 解放军医学杂志

Objective To provide a portable disposable endoscopy for preventing potential viral infection in the patients with acute upper gastrointestinal bleeding (AUGIB) or those who need emergency endoscopy and reducing the process of endoscopy cleaning and disinfection during the corona virus disease 2019 (COVID-19) epidemic. Methods The novel portable and disposable endoscopy system (YunSendo) was self-designed. Two patients with suspected AUGIB underwent emergency gastroscopy with YunSendo system by a senior endoscopist. Standard image acquisition and assessments of operation performance and image quality were fulfilled to evaluate the preliminary safety, feasibility, and operation performance of the novel endoscopy. Results Emergency endoscopy was completed safely in two AUGIB patients by the YunSendo system without alternating current (AC) power supply. The endoscopic manipulation and observation, including water absorption, air inflation, water spray, body rotation, and specimen biopsy, can be smoothly and effectively achieved. The video-recording, image acquisition, and electronic graphic report output were achieved integratedly in YunSendo. The upper GI tract can be clearly visualized, with eligible specimen biopsy without any obvious adverse events and compilations. Operation time was similar to an ordinary gastroscopy. The disposable endoscope was discarded after use according to the requirements of the hospital infection-control department. Conclusions The novel portable and disposable endoscopy system, YunSendo, is safe and feasible for upper gastrointestinal examination, with favorable operation performance and image quality. The preliminary experience provides evidence for its convenient use of epidemic prevention.

Comparison of Clinical Characteristics of Patients with Acute Esophageal Mucosal Lesion and those with Severe Reflux Esophagitis.

BACKGROUND: The term "acute esophageal mucosal lesion (AEML)" includes black esophagitis, and non-black esophagitis characterized by diffuse circumferential erosions without black-appearing mucosa. Black esophagitis is easily diagnosed, whereas non-black esophagitis is often misdiagnosed as severe reflux esophagitis (sRE). The aim of this study was to determine differences in clinical characteristics of patients with AEML and those with sRE. METHODS: Thirty-nine patients with sRE and 32 patients with AEML were diagnosed on the basis of endoscopic findings from 2009 to 2016. Characteristics assessed included age, sex, medication use, coexisting endoscopic finding, comorbidities, laboratory tests results, and chief complaints. RESULTS: In contrast with sRE, male sex, need for emergency endoscopy, presence of duodenal lesions, hypertension, and renal dysfunction were positively associated with AEML. Analysis of associations between laboratory data and AEML showed that high white blood cell count, blood urea nitrogen, and blood glucose were significantly associated with an increase OR for AEML. CONCLUSIONS: We showed that AEML differed from sRE regarding both endoscopic findings and clinicopathological features. AEML has not been widely recognized, but it should be defined as a distinct inflammatory disease of the esophagus consisting of both black and non-black esophagitis.

Differences in the clinical course of 516 Japanese patients with upper gastrointestinal bleeding between weekday and weekend admissions.

BACKGROUND AND AIMS: Patients suspected of having upper gastrointestinal bleeding (UGIB) admitted during the weekend tend to have a poor outcome in western countries. However, no Japanese studies have been reported on this matter. We aimed to evaluate differences in the clinical course of patients with UGIB between weekday and weekend admissions in Japan. METHODS: Medical records of patients who had undergone emergency endoscopy for UGIB were retrospectively reviewed. The severity of UGIB was evaluated using the Glasgow-Blatchford (GB) and AIMS65 score. Patients in whom UGIB was stopped and showed improved iron deficiency anemia after admission were considered as having a good clinical course. RESULTS: We reviewed 516 consecutive patients and divided them into two groups: Group A (daytime admission on a weekday: 234 patients) and Group B (nighttime or weekend admission: 282 patients). There was no significant difference in GB and AIM65 scores between the Groups. The proportions of patients with good clinical course were not significantly different between groups (A, 67.5% and B, 67.0%; p = .90). However, patients in Group B underwent hemostatic treatments more frequently compared with those in Group A (58.5% vs 47.4%, p = .012). Multivariate analysis showed that taking acid suppressants, no need for blood transfusions, use of hemostatic treatments, and GB score <12 were associated with a good clinical course. CONCLUSIONS: There were no significant differences in the clinical outcomes of patients with UGIB admitted during daytime on weekdays and those admitted at nighttime or weekends partly owing to the sufficient performance of endoscopic hemostatic treatments.

Effectiveness of Endoscopic Hemostasis with Soft Coagulation for Non-Variceal Upper Gastrointestinal Bleeding over a 12-Year Period.

BACKGROUND/AIMS: In this study, investigations were carried out to ascertain whether soft coagulation hemostasis for non-variceal upper gastrointestinal bleeding (UGIB) has ever been performed in a time-dependent manner. METHODS: Medical records of 502 patients who had undergone emergency endoscopic hemostasis for non-variceal UGIB from 2003 to 2014 were checked and the modalities were used to achieve hemostasis compared between the first period from 2003 to 2008 (197 patients) and the second period from 2009 to 2014 (305 patients). RESULTS: Endoscopic hemostasis was successfully achieved in 96.0% of study patients. Peptic ulcers were the main cause of bleeding (89.4%). Endoscopic hemostasis was performed by soft coagulation significantly more frequently during the second (71.1%) than the first period (11.7%; p < 0.001). Endoscopic hemostasis was mainly achieved by trainees during the second period (76.1%); these trainees comprised a significantly greater proportion of endoscopists than during the first period (56.3%; p < 0.001). Endoscopic-related complications did not differ between the 2 periods. The only risk factor for rebleeding after hemostasis was Helicobacter pylori infection; the use of soft coagulation and the fact that endoscopists were just trainees were not risk factors. CONCLUSION: Our findings suggest that using soft coagulation to achieve endoscopic hemostasis for non-variceal UGIB is safe and effective, even when it is performed by trainees.

And they were 0.844,83.5%,86.7% and 1.96 mmol/L of serum calcium level by ROC analysis. Conclusion Serum I-FABP combined with calcium can be used for evaluating the effects of emergency surgical on the treatment of the patients with SAP.

Efficacy of Emergency Endoscopic Hemostasis Combined with Somatostatin in Treatment of Upper Gastrointestinal Hemorrhage / 现代生物医学进展

Objective:To discuss the efficacy of emergency endoscopic hemostasis combined with somatostatin in treatment of upper gastrointestinal hemorrhage.Methods:100 patients with upper gastrointestinal hemorrhage were selected and divided into two groups randomly.The control group (48 cases) was given conventional hemostatic measures.The observation group (52 cases) was given emergency endoscopic hemostasis combined with somatostatin.The efficacy of emergency endoscopic hemostasis combined with somatostatin in treatment of upper gastrointestinal hemorrhage was evaluated by efficacy,the curative success rate and the improvement situation of clinical symptoms.Results:The effective rate was 88.5 ％ in the observation group,and the effective rate was 70.8 ％ in the control group,and the effective rate of observation group was higher than that of the control group (P＜0.05).The success rate for different lesion size was higher in the observation group compared with control group (P＜0.05).According to the success rate,with the increased size of lesion,the hemostasis rate was decreased.The hospitalization,negative fecal occult and haematemesis disappeared time of observation group was shorter than that of the control group (P＜0.05).The postoperative bleeding rate of observation group was lower than that of the control group (P＜0.05).Conclusions:The emergency endoscopic hemostasis combined with somatostatin has a good therapeutic effect on upper gastrointestinal hemorrhage.It can improve the clinical symptoms and shorten the hospitalization time,but its effect is limited on large lesion of upper gastrointestinal hemorrhage.

Early lactate clearance for predicting active bleeding in critically ill patients with acute upper gastrointestinal bleeding: a retrospective study.

Not all patients with upper gastrointestinal bleeding (UGIB) require emergency endoscopy. Lactate clearance has been suggested as a parameter for predicting patient outcomes in various critical care settings. This study investigates whether lactate clearance can predict active bleeding in critically ill patients with UGIB. This single-center, retrospective, observational study included critically ill patients with UGIB who met all of the following criteria: admission to the emergency department (ED) from April 2011 to August 2014; had blood samples for lactate evaluation at least twice during the ED stay; and had emergency endoscopy within 6 h of ED presentation. The main outcome was active bleeding detected with emergency endoscopy. Classification and regression tree (CART) analyses were performed using variables associated with active bleeding to derive a prediction rule for active bleeding in critically ill UGIB patients. A total of 154 patients with UGIB were analyzed, and 31.2 % (48/154) had active bleeding. In the univariate analysis, lactate clearance was significantly lower in patients with active bleeding than in those without active bleeding (13 vs. 29 %, P < 0.001). Using the CART analysis, a prediction rule for active bleeding is derived, and includes three variables: lactate clearance; platelet count; and systolic blood pressure at ED presentation. The rule has 97.9 % (95 % CI 90.2-99.6 %) sensitivity with 32.1 % (28.6-32.9 %) specificity. Lactate clearance may be associated with active bleeding in critically ill patients with UGIB, and may be clinically useful as a component of a prediction rule for active bleeding.
