Abstract
Overt or occult gastrointestinal bleeding is a frequently observed condition in routine gastroenterological practice. Occult gastrointestinal bleeding is usually a purely incidental finding, based on the discovery of iron deficiency anemia in the laboratory or blood in stool (a positive Hemoccult test). However, overt bleeding accompanied by the clinical features of tarry stool, hematemesis, or hematochezia may be a life-threatening condition, calling for immediate emergency management. In contrast to traumatology, algorithms of emergency and intensive medicine are not sufficiently validated yet for acute life-threatening bleeding. The purpose of this review was to present all established and new endoscopic hemostasis techniques and to evaluate their efficacy, as well as to provide the treating endoscopist with practical advice on how he/she could incorporate these procedures into acute medical management. The recommendations are based on inspection of the study results in the recent published literature, as well as emergency medicine algorithms in traumatology.

Abstract
BACKGROUND Peptic ulcer is the most common cause of upper gastrointestinal bleeding (GIB) and nutritional support is a helpful strategy in malnutrition prevention during treatment. As early oral feeding in patients with GIB may shorten hospital stay and decrease costs and risk of infection, the present study was carried out to investigate the effects of early oral feeding on relapse and symptoms of upper GIB. METHODS The present clinical trial was conducted with the participation of 100 patients with upper GIB due to gastric or duodenum ulcer at Emam Reza University Hospital in Tabriz. Subjects were randomly allocated to two groups (n=50). In one group, patients received oral diet from day 1 and in other group patients were nil by mouth until day 3 and then received oral diet. Endoscopic and clinical findings of patients were recorded from day 1 to 3. RESULTS The mean age of subjects was 57.6±1.7 and 63% were male. Sclerotherapy was used in most cases as a hemostasis treatment. There was no significant difference in laboratory findings and rebleeding between the two groups. In the group with early oral feeding, the time of hospital stay was significantly shorter than in the control group (P<0.001). CONCLUSION Although early oral feeding had no significant effects on electrolyte balance and treatment outcomes in patients with upper GIB who were treated with endoscopic hemostasis, it could effectively shorten the hospital stay. Consequently, early oral feeding in these patients enables early discharge and reduces the costs of treatment.

Abstract
The upper gastrointestinal bleeding remains the most frequent emergency in gastroenterology. Due to the different therapeutic approach a distinction between the variceal and the non-variceal bleeding has been established. A risk assessment for the individual patient is crucial for timing of the endoscopic procedure as well as for the estimation of prognosis. This review gives an overview on modern therapeutic techniques for both, variceal and non-variceal bleeding highlighting on success rates but also on potential complications of the different therapeutic interventions.

Abstract
The aim of this study was to determine appropriate endoscopic treatment of patients with bleeding ulcers by synthesizing results of randomized controlled trials. We performed dual independent bibliographic database searches to identify randomized trials of thermal therapy, injection therapy, or clips for bleeding ulcers with active bleeding, visible vessels, or clots, focusing on results from studies without second-look endoscopy and re-treatment. The primary end point was further (persistent plus recurrent) bleeding. Compared with epinephrine, further bleeding was reduced significantly by other monotherapies (relative risk [RR], 0.58 [95% CI, 0.36-0.93]; number-needed-to-treat [NNT], 9 [95% CI, 5-53]), and epinephrine followed by another modality (RR, 0.34 [95% CI, 0.23-0.50]; NNT, 5 [95% CI, 5-7]); epinephrine was not significantly less effective in studies with second-look and re-treatment. Compared with no endoscopic therapy, further bleeding was reduced by thermal contact (heater probe, bipolar electrocoagulation) (RR, 0.44 [95% CI, 0.36-0.54]; NNT, 4 [95% CI, 3-5]) and sclerosant therapy (RR, 0.56 [95% CI, 0.38-0.83]; NNT, 5 [95% CI, 4-13]). Clips were more effective than epinephrine (RR, 0.22 [95% CI, 0.09-0.55]; NNT, 5 [95% CI, 4-9]), but not different than other therapies, although the latter studies were heterogeneous, showing better and worse results for clips. Endoscopic therapy was effective for active bleeding (RR, 0.29 [95% CI, 0.20-0.43]; NNT, 2 [95% CI, 2-2]) and a nonbleeding visible vessel (RR, 0.49; [95% CI, 0.40-0.59]; NNT, 5 [95% CI, 4-6]), but not for a clot. Bolus followed by continuous-infusion proton pump inhibitor after endoscopic therapy significantly improved outcome compared with placebo/no therapy (RR, 0.40 [95% CI, 0.28-0.59]; NNT, 12 [95% CI, 10-18]), but not compared with histamine(2)-receptor antagonists. Thermal devices, sclerosants, clips, and thrombin/fibrin glue appear to be effective endoscopic hemostatic therapies. Epinephrine should not be used alone. Endoscopic therapy should be performed for ulcers with active bleeding and nonbleeding visible vessels, but efficacy is uncertain for clots. Bolus followed by continuous-infusion intravenous proton pump inhibitor should be used after endoscopic therapy.

Abstract
The evaluation and management of acute gastrointestinal bleeding in infants, children, and adolescents is a reason for emergency consultation frequently cited by pediatric gastroenterologists. After stabilization of the patient's condition, endoscopic evaluation remains the most rapid and accurate method to identify the origin of acute bleeding in the majority of lesions in the pediatric age group. Several endoscopic techniques may be applied to bleeding lesions to achieve hemostasis. Familiarity with the various techniques and with the specifics of their use is essential for the pediatric endoscopist. This review focuses on the endoscopic management of acute nonvariceal bleeding in infants and children.

Abstract
BACKGROUND Endoscopic hemostasis for upper-GI hemorrhage often is difficult to achieve if the view of the bleeding lesion is poor because of the presence of mucus, blood, and clots. An end hood that facilitates endoscopic hemostatic procedures while simultaneously allowing irrigation of the bleeding site was designed by us. Based on this design, a one-third partial irrigating end hood was developed, and its usefulness for treatment of non-variceal hemorrhage was evaluated. METHODS The end hood was fabricated by drilling a side hole in the cap portion of a transparent end hood. An irrigation tube was glued to the exterior surface over the hole. A "total" (type 1) and a "one-third partial" (type 2) transparent end hood were fabricated. These differ with respect to the proportion of the endoscope circumference that is hooded by the device. The fabricated transparent end hood was placed on the tip of a standard endoscope. With the end hood in place, endoscopic hemostatic treatment under irrigation was performed in 35 patients (type 1 end hood, 18; type 2, 17) with non-variceal upper-GI hemorrhage. OBSERVATIONS Hemostatic treatment was enhanced by simultaneous irrigation beneath the end hood, and hemostasis was successfully achieved in 34 of 35 cases. The time required to achieve hemostasis was significantly shorter in the type 2 group than the type 1 group (median 11.8 vs. 16.9 minutes; p < 0.05). CONCLUSIONS The end hood was extremely useful for endoscopic hemostatic treatment under irrigation. The "one-third partial" end hood is superior to the total end hood in terms of duration of time required to achieve hemostasis.

Abstract
Nonvariceal UGI bleeding is one of the most common emergencies that gastroenterologists encounter, and continues to be a significant cause of morbidity and mortality. The keys to management are rapid resuscitation and stabilization; appropriate triage based on pre-endoscopic risk factors; early endoscopy to achieve prompt diagnosis and implement hemostatic therapy to high-risk lesions; and aggressive antisecretory therapy (in the case of peptic ulcer bleeding) to reduce the risk of continued or recurrent bleeding.

Abstract
BACKGROUND Despite advances in endoscopic treatment methods for upper GI hemorrhage, hemostasis is often difficult to achieve, particularly when the endoscopic view at the site of hemorrhage is poor because of the presence of mucus and blood. The investigators developed an end hood that facilitates endoscopic hemostatic procedures while simultaneously allowing irrigation of the bleeding site. The usefulness of this end hood for treatment of upper GI hemorrhage, excluding hemorrhage from varices, was evaluated. METHODS The end-hood piece was fabricated by drilling a side hole in the cap portion of a conventional transparent hood. An irrigation tube then was glued to the exterior surface of the hole. The fabricated transparent hood was placed on the tip of an endoscope. With the hood piece in place, hemoclip placement and other endoscopic hemostatic procedures were performed in 15 patients with nonvariceal upper GI hemorrhage. RESULTS Hemostasis was successfully achieved in all cases. In all cases of active hemorrhage, hemostatic treatment was enhanced by simultaneous irrigation beneath the hood. The median time required for the hemostatic procedure with the attached hood was 4.8 minutes. CONCLUSION The end-hood irrigation device and technique facilitate endoscopic hemostatic treatment of nonvariceal upper GI hemorrhage.

Abstract
BACKGROUND Intravenous administration of proton pump inhibitors after endoscopic treatment of bleeding peptic ulcers has been shown to decrease the rate of recurrent bleeding and the need for subsequent surgery. Yet there is a relative lack of formal assessment of this practice. The aim of this study was to examine the cost-effectiveness of this therapy by using standard pharmacoeconomic methods. METHODS The present study was performed in conjunction with a randomized controlled clinical trial that included 232 patients who received either omeprazole (80 mg intravenous bolus followed by infusion at 8 mg/hour for 72 hours) or placebo after hemostasis was achieved endoscopically. A cost-effectiveness analysis was performed to evaluate the different outcomes of the trial. All related direct medical costs were identified from patient records. Cost-effectiveness ratios were calculated. RESULTS Analysis by the Kolmogorov-Smirnov test showed that the direct medical cost in the omeprazole group was lower than that for the placebo group. Cost-effectiveness ratios for omeprazole and placebo groups were, respectively, HK$ 28,764 (US$ 3688) and HK$ 36,992 (US$ 4743) in averting one episode of recurrent bleeding in one patient after initial hemostasis was achieved endoscopically. CONCLUSIONS Intravenous administration of high-dose omeprazole appears to be a cost-effective therapy in reducing the recurrence of bleeding and need for surgery in patients with active bleeding ulcer after initial hemostasis is obtained endoscopically.

Abstract
BACKGROUND Despite advances in endoscopic treatment methods for upper GI hemorrhage, hemostasis is often difficult to achieve. This study evaluated the usefulness of endoscopic band ligation for upper GI hemorrhage exclusive of hemorrhage from chronic gastroduodenal ulcer and varices. METHODS This prospective study included 27 patients who underwent endoscopic band ligation and 31 patients in whom bipolar electrocoagulation was performed for upper GI hemorrhage. In both groups, the causes of hemorrhage included Dieulafoy's ulcer, Mallory-Weiss tear, gastric ulcer after polypectomy, and gastric angiodysplasia. Patients with esophageal varices and those with chronic gastroduodenal ulcer were excluded. RESULTS Hemostasis was achieved in all 27 patients in the endoscopic band ligation group and in 26 of 31 patients (83.9%) in the bipolar electrocoagulation group. The median procedure time required for achieving hemostasis was 17.0 minutes (interquartile range: 11.5-23.5) in the endoscopic band ligation group versus 27.0 minutes (interquartile range: 20.5-40.0) in the electrocoagulation group. No major complications occurred in either group. CONCLUSION Endoscopic band ligation is efficient, simple, and safe. Therefore, this technique should be considered as a treatment option for nonvariceal, nonchronic gastroduodenal ulcer upper GI hemorrhage.

Abstract
Re-bleeding and mortality remain significant in peptic ulcer haemorrhage despite the widespread use of endoscopic therapy. The acidic gastric environment interferes with coagulation. In vitro studies show that an intragastric pH of above 6 results in normal blood coagulation and platelet function. Because of induced tachyphylaxis, H(2)-receptor antagonists are not able to maintain a high pH. In addition, in randomized trials using H(2)-receptor antagonists, there was no reduction in re-bleeding and mortality. High-dose intravenous proton pump inhibitors are capable of maintaining a pH above 6. Four randomized trials, using high-dose intravenous proton pump inhibitors, significantly improved the outcome (in terms of a reduction in re-bleeding and surgery) in patients with peptic ulcer haemorrhage. Mortality was, however, not reduced. The additional effect of acid-suppressant agents after successful endoscopic therapy is limited to the reduction of re-bleeding and need for surgery, with no effect on mortality.

Abstract
OBJECTIVE Bleeding is a serious complication of peptic ulcer. Endoscopic injection therapy is accepted as a homeostatic endoscopic treatment in acute nonvariceal of upper GI hemorrhages, particularly in bleeding peptic ulcers. The risk of rebleeding is predicted by the endoscopic appearance of ulcer features classified according to Forrest's criteria. METHODS Two hundred twenty-three patients were selected from 1,003 emergency upper endoscopies for GI bleeding. According to Forrest's criteria, 99 well-matched patients with ulcers F1 and F2 were considered at risk of rebleeding; 54 patients (group A) received local ulcer injection of epinephrine solution 1:10,000, whereas (group B) patients were treated with local epinephrine injection and then with endoscopic Hemoclips. (1) We considered the control of bleeding, the number of rebleeding episodes, the need for emergency surgery, and mortality. RESULTS Bleeding ulcers stopped completely in 83.3% group A patients, and in 95.6% group B patients (p = not significant). In a subset of F1b patients the rebleeding rate was 31 % for group A and 0% for group B (p < 0.05). There was no mortality as a result of the procedure. There was a trend toward reducing surgery in favor of the combined therapy (0% vs 7.4%). No differences were found in transfusion requirements or mean hospitalization days. CONCLUSIONS We conclude that endoscopic injection of l:10,000 epinephrine solution alone and epinephrine solution plus application of Hemoclips are equivalent therapies in treating bleeding and rebleeding from peptic ulcers. There was no difference between therapies in terms of need for surgery or mortality. Possibly combination therapy is more effective in treating ulcers that are actively oozing.

Abstract
Re-bleeding following endoscopic therapy for gastrointestinal bleeding remains common probably because injection and thermal methods for treating bleeding are of limited efficacy, especially in the presence of a large bleeding artery. This chapter reviews mechanical methods of endoscopic haemostasis. The design of clips, which can be delivered through flexible endoscopes, is reviewed with experimental and clinical data of their efficacy. The need for improvements in clip design is stressed. Experimental studies and preliminary clinical data where available on a variety of other mechanical methods of haemostasis are presented, including band ligation, endoloops, sewing machines, stapling machines, ulcer clamps, corkscrews, balloon tamponade and ferromagnetic tamponade. New, less invasive, surgical methods which might have a place in ulcer haemostasis, including transgastric endoluminal surgery and flexible endoscopic ulcer excision with wound closure, are discussed. Mechanical methods offer the best prospect for improvements in security of endoscopic haemostasis for bleeding peptic ulcer. More development is required if the results are to improve.

Abstract
This article provides an overview of the therapeutic endoscopic modalities available for the treatment of peptic ulcer bleeding. The benefits of endoscopic haemostasis have been fully demonstrated by three meta-analyses, which included most of the controlled trials published until 1992. In this review, an emphasis is placed on randomized, prospective comparative trials published during the past 20 years. Using an evidence-based medicine approach, the results of meta-analyses are translated into efficacy measures known as relative and absolute risk reductions, and number needed to treat. Single-modality treatments with injection agents such as epinephrine, sclerosants and thrombogenic substances, or with thermal therapies, are efficacious and comparable. Combination therapy involving injection and thermal techniques may offer an advantage over single-method therapy. The differences in the results between clinical trials and routine clinical practice, and among the various randomized studies, are probably related to operators' experience and variations in technique rather than to inconsistency of endoscopic haemostasis.

Abstract
In the last two decades, significant progress has been made in the diagnosis, prognostication and treatment of patients with severe peptic ulcer haemorrhage. Patients can now be risk stratified by clinical presentation and endoscopic stigmata of ulcer haemorrhage. The purposes of this chapter are to discuss: (1) the techniques of thermal probe with or without epinephrine for haemostasis of ulcers with major stigmata of haemorrhage and (2) the outcomes of treatment of patients with ulcer haemorrhage treated with endoscopic thermal probes or other therapies, medical therapy and/or surgery. Compared to medical therapy alone, patients with major stigmata actively bleeding ulcers, non-bleeding visible vessels and non-bleeding adherent clots have been shown to benefit from endoscopic haemostasis with bipolar probe, heater probe, lasers or epinephrine injection. Outcomes showing significant improvement include blood transfusions, emergency surgery rates and length of hospital stay. Meta-analyses have also reported improvements in mortality for endoscopic compared with medical therapy of patients with severe ulcer haemorrhage and major stigmata. Patients with minor stigmata of ulcer haemorrhage (such as flat spots) or no stigmata (clean-based ulcers) do not benefit from endoscopic haemostasis. Thermal probes have the advantages of good coaptive coagulation, target irrigation, portability and relative inexpense. Recently, patients with active arterial bleeding, non-bleeding adherent clots or non-bleeding visible vessels have been reported to have better results with combination epinephrine injection and thermal probe compared to monotherapy alone (such as injection, bipolar or heater probe). In addition, repeat endoscopic combination therapy has been reported to be as effective but safer than emergency surgery for management of recurrent ulcer haemorrhage.

Abstract
AIM: To evaluate the efficacy of endoscopic hemoclip in the t reatment of bleeding peptic ulcer.
METHODS: Totally, 40 patients with F1a and F1b hemorrhagic activity of peptic ulcers were enrolled in this uncontrolled prospective study for e ndoscopic hemoclip treatment. We used a newly developed rotatable clip-device for the application of hemoclip (MD850) to stop bleeding. Endoscopy was repeated if there was any sign or suspicion of rebleeding, and re-clipping was performed if necessary and feasible.
RESULTS: Initial hemostatic rate by clipping was 95%, and rebl eeding rate was only 8%. Ultimate hemostatic rates were 87%, 96%, and 93% in the F1a and F1b subgroups, and total cases, respectively. In patients with shock on admission, hemoclipping achieved ultimate hemostasis of 71% and 83% in F1a and F1b subgroups, respectively. Hemostasis reached 100% in patients without shock regardless of hemorrhagic activity being F1a or F1b. The average number of clips used per case was 3.0 (range 2-5). Spurting bleeders required more clips on av erage than did oozing bleeders (3.4 versus 2.8). We observed no obvious co mplications, no tissue injury, or impairment of ulcer healing related to hemocli pping.
CONCLUSION: Endoscopic hemoclip placement is an effective and safe method. With the improvement of the clip and application device, the procedu re has become easier and much more efficient. Endoscopic hemoclipping deserves further study in the treatment of bleeding peptic ulcers.

Abstract
OBJECTIVE We report the clinical outcomes and direct medical costs of 155 patients with severe peptic ulcer hemorrhage and a nonbleeding visible vessel at emergency endoscopy treated with endoscopic hemostasis or medical-surgical therapy. METHODS In two consecutive, prospective, randomized, controlled trials, patients were randomly assigned to endoscopic hemostasis (heater probe, bipolar electrocoagulation, or injection sclerosis) or medical-surgical treatment. Study endpoints included the incidence of severe ulcer rebleeding and emergency surgery, length of hospital stay, blood transfusion requirements, mortality rate, and direct costs of utilized health care. Direct medical costs were estimated using combined fixed and variable institutional costs for consumed resources and Medicare reimbursement rates. RESULTS Compared with medical-surgical treatment, endoscopically treated patients had significantly lower rates of severe ulcer rebleeding (p = 0.004), emergency surgery (p = 0.002 and p = 0.019, 0.024), and blood transfusions (p = 0.025). Observed inter-trial differences in ulcer rebleeding rates may be partially explained in a multivariate model by covariates of comorbid disease and inpatient ulcer bleeding. In both trials, length of hospital stay, mortality rates, and treatment-related complications were similar. Estimated median direct costs per patient differed: The first trial had lower costs with endoscopic hemostasis ($4254, vs $4620 for electrocoagulation and $5909 for medical-surgical treatment), yet the second trial yielded lower costs with medical-surgical treatment ($3169, vs $3477 for injection sclerosis and $4098 for heater probe). CONCLUSIONS Compared with medical-surgical therapy, endoscopic hemostasis for severe ulcer hemorrhage and a nonbleeding visible vessel yielded significantly better patient outcomes and was safe. This procedure may or may not yield lower direct medical costs and cost savings.

Abstract
The role of endoscopic therapy for peptic ulcer bleeding is well-documented. Nevertheless, rebleeding occurs in 10% to 30% of patients, and such patients are at high risk for death without early retreatment or definitive surgery. The aim of our study was to predict which patients would rebleed within 1 month after successful multipolar electrocoagulation of 100 patients with active peptic ulcer bleeding (spurting, oozing, or nonbleeding visible vessel). We had achieved initial hemostasis in 97 patients and carried out univariate and multivariate analyses to predict which patients would rebleed. Rebleeding occurred within 1 month in 17 (17.5%) patients. we correlated 20 clinical and endoscopic factors with rebleeding episodes. With univariate analysis, blood transfusion of 500 ml or more at entry (p < 0.0001) and use of cimetidine (p = 0.01) were statistically significant for rebleeding. With multivariate analysis, use of omeprazole was an independent factor for preventing rebleeding (odds ratio, 7.68; 95% confidence interval, 1.642-35.929). We suggest that omeprazole may help to prevent rebleeding in patients who have had hemostasis with multipolar electrocoagulation.

Abstract
BACKGROUND Ageing populations are increasing in many countries and bleeding peptic ulcers in patients older than 60 years carry a greater risk of rebleeding and death. This study aimed to identify the risk factors for rebleeding and death in very elderly patients with peptic ulcer bleeding. The efficacy of treatment in preventing recurrent bleeding and death in this group of patients was also studied by means of prospective data collection and analysis. METHODS Data relating to 1744 patients treated between September 1985 and January 1994 for peptic ulcer bleeding were collected prospectively and analysed. Patients were stratified by age to one of three groups: group 1 (less than 60 years, n = 833), group 2 (60-79 years, n = 706) and group 3 (80 or more years, n = 205). RESULTS Univariate and multivariate analyses of 21 factors possibly affecting either rebleeding or death identified age greater than 80 years as one of the factors significantly affecting rebleeding and death. In a comparison of groups 1, 2 and 3, the likelihood of rebleeding and death was significantly greater in group 3. Univariate and multivariate analyses for rebleeding and death were performed for each group. The severity of initial bleeding had a marked bearing on subsequent rebleeding rates for all three groups. In group 3, however, large ulcer size and impaired liver function were additional factors which correlated significantly with final outcome. No rebleeding or morbidity occurred when endoscopic treatment was performed early for patients in group 3 but there was a significantly greater risk of further recurrent haemorrhage and treatment-related morbidity when treatment was performed after the onset of rebleeding. CONCLUSION Patients aged 80 years or greater had the highest risk of rebleeding and death. For patients below 80 years of age, significant factors related to a fatal outcome included co-morbid illness, complications and the need for mechanical ventilation. For patients aged 80 years or older, the significant factors were ulcer size greater than 2 cm and admission with serum bilirubin level above 20 mmol/l. Endoscopic treatment for the very elderly was effective if carried out early.

Abstract
BACKGROUND There are no published, detailed assessments of the direct costs of endoscopic hemostasis for actively bleeding peptic ulcers. We compared the direct costs of care for patients with active ulcer hemorrhage treated with endoscopic or medical-surgical therapies and correlated these costs with patient outcomes. METHODS In a prospective, randomized, controlled trial, 31 patients with active ulcer hemorrhage at emergency endoscopy were randomly assigned to heater probe, injection, or medical-surgical treatment. For further ulcer bleeding, heater probe and injection patients were re-treated endoscopically and medical-surgical patients were referred for surgery. Direct costs were estimated using fixed and variable costs for resources consumed and Medicare reimbursement rates for physician fees. RESULTS Compared to medical-surgical treatment, the heater probe and injection groups had significantly higher primary hemostasis rates (100% and 90% vs 8%) and lower rates of emergency surgery (0% and 10% vs 75%), blood transfusions, and median direct costs per patient ($4153 and $5247 vs $11,149). Furthermore, compared to medical-surgical treatment, the heater probe group had a significantly lower incidence of severe ulcer rebleeding (11% vs 75%). CONCLUSIONS Heater probe and injection sclerosis are similarly efficacious treatments for active ulcer hemorrhage, and both treatments yield significantly lower direct costs of medical care and cost savings.

Abstract
The choice of therapeutic endoscopic technique depends on the training and equipment available to the endoscopist. If the technique is properly performed, the results are similar using injection, thermal coagulation, or laser therapy. We recommended that pediatric endoscopists concentrate on one thermal and one injection technique, since individual bleeding lesions may be more amenable to one method than another based on their anatomic location or briskness of bleeding.

Abstract
The average hospital cost to manage patients hospitalized at Virginia Mason Hospital who bleed from a peptic ulcer is approximately $5000 per patient in our series of 30 patients. Because there are 150,000 admissions per year in the United States for peptic ulcer bleeding, the total hospital cost can be estimated to be $750 million. The actual cost may be higher because our 30 patients had minimal complications and were discharged on average in less than 4 days. The majority of hospital cost is incurred by the intensive care unit or the hospital nursing floor. There is a close to linear relation between the length of stay and the total hospital cost. Upper gastrointestinal endoscopy is a major advance in the treatment of peptic ulcer bleeding. It can provide significant cost savings by identifying some patients with bleeding peptic ulcers who have clean bases on endoscopy who are then eligible for prompt discharge from the hospital. In addition, endoscopic thermal therapy (with multipolar electrocautery or heater probe) and injection therapy cost less than $50 in incremental cost and can reduce further bleeding by 43%, reduce the need for urgent surgery by 63%, and reduce the mortality rate by 60%. Some patients still require urgent surgical intervention, which is substantially more costly than endoscopic hemostasis but is highly effective. Preliminary studies show promise in predicting further bleeding, with clinical scoring systems such as the Baylor Bleeding Score and with the use of Doppler ultrasonography. Better prediction of further bleeding should guide the choice of durable hemostasis early in the hospitalization. Additional studies should clarify the role of NSAID avoidance and H. pylori eradication in the long-term prevention of recurrent peptic ulcer bleeding.

Abstract
BACKGROUND Despite improved surgical and endoscopic technics, acute bleeding from peptic ulcer is still a serious condition, and management remains controversial. The aim of the study was to evaluate a management policy of aggressive endoscopic and restrictive surgical treatment for acute peptic ulcer bleeding. METHODS We retrospectively investigated the course of all 341 hospital admissions during 1986 to 1990 caused by bleeding peptic ulceration from the first bleeding episode until 30 days after discharge. RESULTS Total mortality, in-hospital 30 days' mortality, and operative mortality were 6.3%, 4.4%, and 23.5%, respectively. Risk factors associated with mortality were age and number of concomitant diseases, malignant disease, rebleeding episodes, and surgical complications. No patients without associated illness died. In 73 cases (21%) patients were treated endoscopically one or more times, and altogether 17 patients (5%) were operated on. Rebleeding occurred in 67 cases (23%), and only 23 of these were treated endoscopically at admission. Twenty-six (51%) of the rebleeding patients were treated endoscopically and 13 rebleeding patients were operated on. Two-thirds of patients presenting with arterial bleeding were managed endoscopically. No complications occurred in endoscopically treated patients, whereas there were complications in 8 of 17 operated patients. Operated patients needed significantly more intensive care unit observation time and had longer hospital stay than patients treated endoscopically. CONCLUSIONS Endoscopic treatment is a safe procedure with a low mortality, and, if successful, the need for emergency surgery is substantially reduced. In the relatively few patients requiring surgery after unsuccessful endoscopy, the mortality remains high.

Abstract
A controlled, randomised study was performed to evaluate the efficacy of treatment with heater probe in the prevention of rebleeding from peptic ulcer with a non-bleeding visible vessel. One hundred and one patients were randomised into two groups: patients to be treated by heater probe (n = 51) and controls without active treatment (n = 50). In the heater probe group rebleeding occurred in five patients (10%) v 13 (26%) in the control group (p = 0.03), with a comparative risk of 0.38 in favour of the heater probe group. The difference in proportions of successful treatment for each group was 16.2% in favour of the heater probe (95% CI = 2 to 31%). Haemorrhage directly related to heater probe treatment occurred in four patients. In three of them bleeding was easily controlled by further heater probe pulses. There were no other complications and no death in the heater probe group. One patient in the control group died of pulmonary embolism. No significant differences in the length of stay in hospital, blood transfusions, surgical rates, or death were found; the design of the study, however, precluded an adequate assessment of these variables, because the heater probe was an optional rescue treatment when high surgical risk patients rebled. These results suggest that the heater probe is an effective and safe procedure in the prevention of recurrent haemorrhage in peptic ulcer with a non-bleeding visible vessel.

Abstract
The approach to nonvariceal UGI bleeding has been reviewed. Therapeutic endoscopy has been shown to be superior to medical therapy in patients with an actively bleeding ulcer and those at high risk of rebleeding. Of endoscopic therapies available to the GI endoscopist, multipolar electrocoagulation, heater probe, and injection therapy are comparable in efficacy and safety.

Abstract
A prospective, randomized comparative study was performed to compare the hemostatic effect of endoscopic injection with normal saline, 3% NaCl solution, 50% glucose/water solution, and pure alcohol during a period of 2 years. Only patients with peptic ulcers and active bleeding or nonbleeding visible vessels were considered. Each group comprised 50 patients. The four groups were matched at random for age, sex, location of bleeders, stigmata of recent hemorrhage, shock, hemoglobin, and concomitant illness. No statistically significant difference was observed among patients injected with normal saline, 3% NaCl solution, 50% glucose/water solution, or pure alcohol in achieving initial hemostasis (82%, 90%, 86%, and 92%, respectively); rebleeding rates (7.3%, 24.4%, 14%, and 10.9%, respectively); ultimate hemostasis (78%, 68%, 78%, and 84%, respectively); number of emergency operations (5, 7, 4, and 3, respectively); and average number of days in the hospital (6.7, 6.1, 6.1, and 5.8, respectively). A tendency toward a lower blood transfusion requirement was observed in the pure alcohol group, but this tendency failed to achieve statistical significance. One patient had a perforated ulcer develop 5 days after injection of 3 ml 50% glucose/water. Otherwise, no major complication was observed. We suggest that endoscopic injection with any of the above solutions can be used as the first-line modality for the arrest of peptic ulcer hemorrhage.

Abstract
Bleeding duodenal and gastric ulcers continue to be a common and serious problem. Definition of the precise appearance and location of the ulcer by endoscopy gives important information about the source of bleeding and additional information about the risk of rebleeding and the indications for surgery. Several endoscopic hemostatic methods are available. The nonerosive contact probes (heater and BICAP) are preferred. Injection therapy with vasoconstrictors or sclerosing agents can also be recommended as a safe, efficacious, and economical means of treatment. Several hemostatic modalities should be available for use depending on the anatomic location and type of bleeding ulcers. The collaboration of skilled interventional endoscopists with their traditional surgical colleagues offers the patient with bleeding peptic ulcer disease the optimum probability of a successful outcome, with minimum treatment-associated morbidity.
