Acute upper gastrointestinal hemorrhage in patients with chronic renal disease

In order to reassess the role of duodenal ulcers as a cause of acute upper gastrointestinal hemorrhage in patients with chronic renal failure, 20 consecutive patients with moderate to severe chronic renal failure and a comparison group of patients without renal disease who were seen for acute upper gastrointestinal hemorrhage were reviewed. Gastric bleeding sites (gastric ulcer in 35 percent and gastritis in 20 percent) rather than duodenal ulcers were the most common sources of bleeding and were significantly associated with the use of ulcerogenic drugs. Patients with renal disease in whom acute upper gastrointestinal hemorrhage developed had significantly more morbidity and a trend toward higher mortality than the comparison group of patients without renal disease. It is concluded that gastric mucosal lesions, at least in part due to the use of ulcerogenic drugs, are the most common cause of significant acute upper gastrointestinal hemorrhage in patients with chronic renal failure.     

Uncontrolled thrombocytosis in chronic myeloproliferative disorders

S ummary . A retrospective study was performed to examine the natural course of uncontrolled thrombocytosis associated with chronic myeloproliferative disorders. Thirty-eight patients with polycythaemia rubra vera (PV), myelofibrosis/myeloid metaplasia (MM), chronic myelogenous leukaemia (CML) or essential thrombocythaemia (ET) had platelet counts greater than 1000 × 10⁹/1 and were followed closely for a total of 246 patient years. Eleven of the patients experienced haemorrhagic episodes. Bleeding was twice as frequent in patients over 59 years old as in those younger and no bleeding occurred in those less than 51 years of age. There was no correlation between frequency of bleeding and extent of thrombocytosis. Bleeding events occurred concurrently with use of anti-inflammatory agents in 32% of episodes. The gastrointestinal tract was the most frequent site. Documented thrombotic events occurred in three patients, two of whom had PV with haematocrits greater than 53%. This study suggests that the thrombocytosis of myeloproliferative processes may pose a less serious threat than originally thought and that aggressive lowering of the platelet count may not be indicated in all cases.     

Clinical picture of peptic ulceration diagnosed endoscopically.

Clinical features and laboratory data are presented for 100 patients with benign gastric ulceration and 150 patients with duodenal ulceration confirmed endoscopically in a district general hospital unit. Abdominal pain was the commonest indication for endoscopy, but one third of examinations were performed for acute gastrointestinal haemorrhage. Although the patients were selected by referral for endoscopy their clinical presentation, age, and sex distribution were similar to those reported in previous general surveys. There were no clinical features which clearly distinguished gastric from duodenal ulceration. However, of those with gastric ulceration younger patients more often had distal ulcers and presented with pain, while elderly subjects tended to have high lesser curve involvement and presented with haemorrhage. Moreover, all females presenting with haemorrhage were aged over 50 years, while 6% of males bleeding from gastric ulceration and 40% of males bleeding from duodenal ulceration were under this age. Anaemia when present, except in two premenopausal females, indicated either a recent acute gastrointestinal haemorrhage or a coexistent second diagnosis.     

Clinically manifest gastrointestinal bleeding in patients subject to coronary angiography

PATIENT SET AND METHODOLOGY: The authors evaluated the incidence of acute bleeding from the upper gastrointestinal tract in 5,955 patients (of which 3,684 men and 2,271 women) during hospitalisation for coronary angiography, and the incidence of potential sources of bleeding from the upper gastrointestinal tract in the patients without bleeding. RESULTS: Bleeding occurred in 9 persons, within 3.4 +/- 3.6 days of the coronary angiography (the median of 1.0 day), with a 33% mortality rate. An ulcer of the duodenal bulbus or bulbitis were detected in four cases (44%), esophagitis in one case (11%), esophageal varices in one case, stomach carcinoma in one case, and the source of bleeding could not be detected in 2 cases. Patients with bleeding were significantly older than those without bleeding (73.6 +/- 4.4 years vs. 65.8 +/- 10.6 years, p < 0.001). Treatment with clopidogrel or abciximab was not associated with a higher incidence of bleeding (p > 0.05). In 42 patients without bleeding, the following pathologies were detected by gastroscopy: esophagitis (31%), mouth and stomach ulcers (36%), duodenal ulcers (21%), (12%), esophageal varices (2%) The incidence of mouth ulcers, stomach ulcers and duodenal ulcers was significantly higher in patients taking acetylsalicylic acid on a regular basis (p < 0.025). CONCLUSION: Bleeding from the upper gastrointestinal tract is not frequent shortly after coronary angiography, but the related mortality is high. The most frequent source of bleeding are duodenal peptic lesions most likely caused by previous treatment by acetylsalicylic acid.     

Duodenal ulcers dominate acute upper gastrointestinal tract bleeding in childhood: a 10-year experience from Hong Kong

OBJECTIVE: Systematic reports on acute upper gastrointestinal bleeding in children/adolescents are scanty. The aim of this study is to analyze its presentation, pathology and outcome in Hong Kong. METHODS: A retrospective review of the hospital database for admissions up to the age of 18 years with signs of acute upper gastrointestinal bleeding between 1 June 1996 and 31 May 2006. RESULTS: During the 10‐year period 76 patients (55 boys) were admitted with signs of upper gastrointestinal bleeding. The median age was 13.5 (range 0.25–18) years. Melena and hematemesis were by far the most frequent presentations. Medication was implicated in 16 cases (21%) as the possible cause for the bleeding. Endoscopic findings were a duodenal ulcer in 57 (75%) patients (50 boys) and a gastric ulcer in eight (10.5%). Helicobacter pylori infection was identified in 42 (55%) patients, of which 38 were found in duodenal ulcer patients. Eleven patients (14.5%) had interventions to achieve hemostasis: six epinephrine spray only, three thermal probe and two vessel ligation. After a median follow‐up time of 3.5 years six patients had a recurrent duodenal ulcer. Three patients died of unrelated illnesses. CONCLUSION: Acute upper gastrointestinal tract bleeding in children and adolescents in Hong Kong is dominated by a duodenal ulcer in 75% of the patients. Acute bleeding is more frequent in boys (boy to girl ratio 2.6:1). Medication is a predisposing factor in 20% of the bleedings. Six patients (8%) have recurrent duodenal ulcers.     

High incidence of Dieulafoy's lesions in upper gastrointestinal bleeding associated with polyarteritis--clinical examination of patients of polyarteritis nodosa with rapidly progressive glomerulonephritis

BACKGROUND/AIMS: Polyarteritis nodosa (PN) has been classified into polyarteritis (PA) and microscopic polyarteritis (MA) histologically. To clarify of the characteristics of upper gastrointestinal bleeding lesions in PN, we investigated the patients of PN with rapidly progressive glomerulonephritis (RPGN) presenting with upper gastrointestinal bleeding. METHODOLOGY: The subjects of this study were 21 patients of PN with RPGN (PA: 11, MA: 10) who presented with upper gastrointestinal bleeding. The bleeding lesions and their locations were examined endoscopically in the study subjects, and the relationship of the bleeding to the severity of renal failure, the necessity of hemodialysis (HD), presence/ absence of H. pylori infection and the gender of the patients were analyzed. RESULTS: The bleeding lesions were endoscopically identified as esophageal ulcers in 2 cases, gastric ulcers in 15 cases and duodenal ulcers in 4 cases, respectively. In 10 of the 15 cases with gastric ulcers, the ulcer assumed the form of Dieulafoy's lesions affecting the gastric body, and the underlying disease was PA in all the 10 cases. In the remaining 5 cases of gastric ulcers and 2 cases of esophageal ulcer with underlying MA or 4 cases of duodenal ulcers, in whom assumed the bleeding form of oozing from the marginal zone of ulcers. In all of the 4 cases of duodenal ulcers, and the 1 case with underlying PA and the other cases with MA, no correlation was found between the onset of the upper gastrointestinal bleeding and the severity of renal failure or the necessity for HD, presence of H. pylori infection, or the gender of the patients. CONCLUSIONS: Dieulafoy's lesions are the most frequent sources of upper gastrointestinal bleeding in cases of PA.     

Treatment of severe peptic ulcer haemorrhage with the heat probe

From September to December 1986, 30 cases of persistent upper gastrointestinal bleeding were collected and treated, via the endoscope, with a heat probe. All cases had either gastric or duodenal ulcers. Ten cases were in shock. After treatment, all bleeding episodes initially stopped, but six cases (20%) re-bled. Five cases received repeat heat probe therapy and did not re-bleed thereafter. Thus the ultimate success rate was 96.7% (29/30). Twenty of 21 ulcers (94.3%) were found to be healed with scars 2 months after therapy. During therapy and the follow-up period, only one complication occurred and this was a mild aspiration pneumonia. The heat probe is an ideal haemostatic device for severe non-variceal upper gastrointestinal bleeding.     

Factors influencing mortality from bleeding peptic ulcers

The mortality, causes of death, and the factors that are influencing deaths from bleeding acute and chronic peptic ulcers were evaluated retrospectively. During a 2-year period (1986-87) 272 patients were endoscoped for acute gastrointestinal hemorrhage and were found to have bled from a peptic ulcer (chronic gastric ulcers, 90; chronic duodenal ulcers, 114; acute gastroduodenal ulcers, 66; stomal ulcers, 2). The overall mortality was 9.6% (n = 26) (gastric ulcers, 6.7%; duodenal ulcers, 11.4%; acute ulcers, 10.6%). Statistically significant factors adversely affecting prognosis for gastric ulcer were re-bleeding, need for operation and serious intercurrent illness; for duodenal ulcer were units of transfused blood, re-bleeding, signs of recent hemorrhage at endoscopy, need for operation, and serious intercurrent illness; and for acute ulcer were increasing age, shock, units of transfused blood, re-bleeding, and serious intercurrent illness. Multivariate analysis was only attempted for duodenal ulcers because of sample sizes; it suggested that active bleeding or visible vessel at endoscopy, re-bleeding, and serious intercurrent illness were independent factors for mortality. From this study it is apparent that the major determinants of a fatal outcome in bleeding peptic ulcer diseases were serious intercurrent illness and rebleeding. As it must be anticipated that patients with these particular problems are at high risk of a poor outcome, it follows that it is important they have access to skilled treatment as provided by a specialist team in an intensive care ward. It also follows that every effort should be made to keep ulcers in remission to free the ulcer patient of potentially lethal complications.     

Seasonal changes in symptomatic duodenal ulcer activity in Taiwan: a comparison between subjects with and without haemorrhage

Abstract. Tsai C-J, Lin C-Y (Chi Mei Foundation Hospital, Tainan, Taiwan). Seasonal changes in symptomatic duodenal ulcer activity in Taiwan: a comparison between subjects with and without haemorrhage. J Intern Med 1998; 244 : 405–10.

Objectives

To examine if climatic changes may influence the presentation of pain and haemorrhage in patients with duodenal ulcers.

Design

Cross-sectional study.

Setting

Tertiary referral centre.

Subjects

A total of 10 331 symptomatic duodenal ulcer diseases were diagnosed from 1989 to 1996. The patients who had any extrinsic factors that might influence the exacerbation of duodenal ulcer were not included. Patients were divided into those whose ulcer bled once or repeatedly as distinct from those whose ulcers caused pain without haemorrhagic complications. Patients with acute cholangitis diagnosed in the same period were studied as controls.

Results

During the 7-year period, 10 331 symptomatic duodenal ulcer diseases were diagnosed. Amongst these, 5328 showed active duodenal ulcer without haemorrhage, 2088 showed acute duodenal ulcer with stigmata of recent haemorrhage, and 2915 showed a deformed bulb. The incidence of total duodenal ulcers showed significant monthly variation and was found to be more common from November to March (P < 0.001). The monthly incidence of total episodes of upper gastrointestinal tract bleeding peaked from November to March (P < 0.001) with significant variation. The monthly incidence of bleeding episodes from duodenal ulcer only was the same (P < 0.001). In patients whose duodenal ulcers repeatedly caused pain without haemorrhage, there were significant monthly fluctuations, with peak months from December to March (P < 0.001). In the control diagnosis, there were no significant calendar variations (P = 0.85).

Conclusions

Our study has shown that both groups of patients demonstrated similar monthly fluctuations. The incidence is significantly higher during the cold seasons. These data suggest that climatic changes may influence the presentation of pain and haemorrhage in duodenal ulcer patients.

Results of the management of upper gastrointestinal bleeding from gastroesophageal varices.

INTRODUCTION: The management of upper gastrointestinal bleeding caused by rupture of gastric and/or esophageal varices in patients with liver cirrhosis must focus on the initial control of the haemorrhage avoiding further worsening of an already poor liver function and the prevention of early relapsing bleeding. Therapeutic options include endoscopic, pharmacological and surgical methods. MATERIAL AND METHODS: Prospective study of the results obtained after the follow-up of 90 bleeding episodes in a total of 54 patients, 35 men and 19 women, with a mean age of 58 years (range 32-77), to which a therapeutic protocol for acute bleeding secondary to portal hypertension was applied over a 22-months period. Patient classification according to Child-Pugh upon admission was 57% Child A, 34% Child B and 9% Child C. RESULTS: Mean hospital length of stay was 9 days (2-50). Of the 90 bleeding episodes, 15 were early relapsing bleeding episodes (16.7%). Twelve patients died (mortality rate of 22.2% by patients and 13.4% by bleeding episodes). Twelve emergency surgical procedures were performed because of the persistence of haemorrhage. Forty one per cent of patients were readmitted because of relapsing bleeding at least once during the follow-up period. CONCLUSIONS: Management of upper gastrointestinal bleeding due to gastroesophageal varices in patients with liver cirrhosis requires a combined therapy in order to attain maximum effectiveness in acute haemorrhagic episodes and to address all potential later consequences. Such therapy should be provided in a hospital fully equipped and with specialists in this pathology. Based on our experience, emergency surgery as rescue treatment for persistent or short-term relapsing bleeding should be restricted to patients with good hepatic function because of its high morbidity and mortality.     

Endoscopic ethanol sclerotherapy in non-variceal gastrointestinal bleeding

Upper gastrointestinal bleeding still causes significant morbidity and mortality in spite of an aggressive medical and surgical approach. Endoscopic methods of treatment promise early and effective non-surgical control of bleeding. Endoscopic injection of ethanol has been used to control gastrointestinal bleeding in a prospective study of 28 high risk patients. Twenty-two had chronic ulcers (12 duodenal, 10 gastric) and six had angiodysplastic lesions (three gastric, three caecal). The 22 patients with chronic peptic ulcers were either elderly (median age 69 years) or had serious associated medical disorders (73%); 64% presented with shock. Primary haemostasis was achieved in all, but two re-bled from their ulcer. Surgery was required in one patient who re-bled 48 h after treatment and in one patient with an ulcer which perforated 45 days after injection; three patients with chronic ulcers refractory to medical therapy also underwent surgery. One patient developed a closed perforation of an antral ulcer after treatment which settled with conservative management; two patients died from causes unrelated to their ulcer. It is concluded that ethanol sclerosis is a safe, effective method for controlling bleeding from chronic peptic ulcers and angiomatous malformations.     

Enhanced gastric mucosal haemostasis after upper gastrointestinal haemorrhage.

An endoscopic technique for the measurement of gastric mucosal bleeding time has been developed to study gastric haemostasis in patients with acute upper gastrointestinal haemorrhage. The relation of gastric mucosal bleeding time to skin bleeding time and nonsterodial anti-inflammatory drug usage was examined in 61 control patients and in 47 patients presenting with bleeding peptic ulcers or erosions. Gastric mucosal bleeding time was shorter in patients with haemorrhage (median 2 minutes, range 0-5 minutes) than in the control group (median 4 minutes, range 2-8 minutes) (p less than 0.001). Skin bleeding times were similar in the two groups (medians 4 minutes in patients with haemorrhage and 4.5 minutes in controls). In 21 patients with haemorrhage who were taking non-steroidal anti-inflammatory drugs, the median gastric mucosal bleeding time (2.5 minutes, range 1.0-5.0 minutes) was similar to that in 26 patients with haemorrhage not associated with these drugs (2.0 minutes, range 0.0-5.0 minutes). These results show that gastric mucosal haemostasis is accelerated in response to haemorrhage in the upper gastrointestinal tract, even in patients taking nonsteroidal anti-inflammatory drugs. This enhanced gastric haemostasis probably reflects a local protective response to minimise blood loss from the bleeding lesion.     

Helicobacter pylori infection in patients with haemophilia in Poland: prevalence and risk of upper gastrointestinal bleeding

Infection with Helicobacter pylori is the main aetiological factor for erosive gastritis and duodenal or gastric peptic ulcers often complicated with life-threatening bleeding in patients with coagulation disorders. The aim of this prospective study was to evaluate the prevalence of Helicobacter pylori infection in haemophilia patients, and to assess the risk of gastrointestinal bleeding associated with this infection. From 2000 to 2002, 146 patients with haemophilia (129, haemophilia A; 13, haemophilia B), mean age, 39.9 years (+/-7.3), were investigated for H. pylori infection using IgG and IgA latex serological test. The control group included 100 men with no coagulation disorders, mean age, 40.9 years (+/-9.2). For 72 (49.3%) patients with haemophilia and 39 controls (39.0%) serological tests were positive indicating the presence of H. pylori infection (P =0.1112). A history of gastrointestinal bleeding was reported in 46 patients (31.5%) with haemophilia and in two control group patients (2.0%) (P < 0.0001). Gastrointestinal bleeding was significantly more frequent in patients with haemophilia infected with H. pylori (33/46; 71.7%) than in patients with no H. pylori infection (13/46; 28.3%; P = 0.0002). In conclusion, the prevalence of H. pylori infection in haemophilic patients in Poland is comparable with that in patients with no coagulation disorders. Helicobacter pylori infection is a risk factor for duodenal and gastric ulcer bleeding in haemophilia patients. In view of the high frequency of upper gastrointestinal bleeding associated with H. pylori infection, we believe that screening and eradication therapy are appropriate in haemophilia patients.     

Endoscopic cautery using the heater probe as an alternative to operation for massive gastroduodenal haemorrhage

Endoscopic cautery using the heater probe has been used by the author since 1981 for treatment of acute gastroduodenal haemorrhage. The technique has been used as an alternative to immediate operation in 175 patients who had clearly demonstrated a need for intervention. All 175 had suffered recurrent haemorrhage in hospital to a blood transfusion requirement of at least 3 litres. Ulcer patients were selected by being over 60 yrs old or otherwise unfit for operation. Early experience showed that the technique was not reliable for patients bleeding from large posterior duodenal ulcers, so 35 old or sick patients with duodenal ulcer were excluded from the series. There were no exclusions with patients bleeding from lesions proximal to the pylorus, and 82% of these were sucessfully treated. Even with avoidance of large posterior ulcers, only 47% of duodenal ulcer patients were able to safely avoid an operation. It is concluded that heater probe cautery can replace emergency operation in most patients bleeding from gastric lesions, but it has a limited role for patients bleeding from duodenal ulcer.     

Peptic ulceration in patients with chronic liver disease

A prospective study was undertaken to determine the frequency of peptic ulceration in different forms of chronic liver disease and the effect of corticosteroid treatment. One hundred sixty-three patients with chronic liver disease underwent upper gastrointestinal endoscopy, 106 for investigation of dyspeptic symptoms and the remaining 57 for assessment of the presence of varices. Twenty-four peptic ulcers were found (14.7%), 12 duodenal, 8 gastric, and 4 prepyloric. Ulcers were found in 5 of 15 patients with hepatitis B surface-antigen-positive chronic active liver disease (33%), 10 of 46 patients with alcoholic liver disease (22%), 5 of 35 with primary biliary cirrhosis (14%), 2 of 19 with miscellaneous chronic liver diseases (10%), and 2 of 25 with cryptogenic cirrhosis (8%). Ulcers were not demonstrated in any of the 23 patients with hepatitis B surface-antigen-negative chronic active hepatitis. Thirty-one patients were receiving prednisolone therapy, 5 had peptic ulcer compared with 19 of the remaining 132 patients. This difference was not significant. Fifty-nine patients presented with gastrointestinal bleeding on 88 separate occasions. Peptic ulcer was the cause in 6% of these. In chronic liver disease peptic ulcers occurred with differing frequencies in different forms of the disease. This was unaffected by corticosteroid therapy. Peptic ulcers were rarely the cause of gastrointestinal bleeding.     

Comparison of Diagnostic Methods for Helicobacter pylori Infection in Patients with Upper Gastrointestinal Bleeding

Background: Accuracy of the most frequently used tests for diagnosing Helicobacter pylori infection in patients with upper gastrointestinal bleeding of peptic origin is determined. Methods: Seventy-eight patients with endoscopically-proven upper gastrointestinal bleeding of peptic origin were included. The presence of H. pylori was considered when observed from the histology or, if negative, when serology and breath test were both positive. Accuracy of the rapid urease test was estimated in accordance with results obtained with other diagnostic methods. Results: Lesions causing gastrointestinal bleeding were 56 duodenal ulcers, 13 gastric ulcers, 7 pyloric channel ulcers, 13 acute lesions of the gastric mucosa and 16 erosive duodenitis. H. pylori infection was present in 68 patients (87.2%). Forty-four patients had received non-steroidal anti-inflammatory drugs. The sensitivity/specificity (%) of the diagnostic methods was 48.5/100 for the rapid urease test, 91/77.8 for the breath test, 89.5/80 for serology and 86.3/100 for histology. The prior consumption of proton-pump inhibitors and antibiotics induced false-negative results in the rapid urease test and breath test, with no effect on serology and histology. Conclusions: The prevalence of H. pylori infection in patients with upper gastrointestinal bleeding from peptic lesions is high. Sensitivity of the rapid urease test for diagnosing H. pylori is low in this setting. Cases with negative rapid urease test need the combination of two or more additional tests if diagnosis is to be achieved. Cases with positive rapid urease test do not need further investigation for diagnosis.

Cimetidine reduces the risk of rebleeding from duodenal ulcers displaying signs of recent haemorrhage

The presence of endoscopic signs of recent haemorrhage (SRH) greatly increases the risk of rebleeding from peptic ulcers. Fifty-five patients with acute bleeding from chronic duodenal ulcers with SRH completed a randomized double-blind trial to assess the effect of administration of cimetidine (800 mg daily intravenously for 2 days, then 1000 mg daily orally for 10 days in divided doses) versus placebo on rebleeding and need for emergency surgery. In the cimetidine group (n = 29), 5 rebled, compared with 11 receiving placebo (n = 26) (p less than 0.05; relative risk, 0.28, 95% confidence interval, 0.08-0.97). This reduction in rebleeding rate in the cimetidine-treated patients was observed only in subjects over 60 years of age. Fifteen patients receiving cimetidine required blood transfusion (mean, 2.3 +/- 0.6 (SEM) units per patient) compared with 19 receiving placebo (3.5 +/- 0.5) (p greater than 0.1). Emergency surgery to arrest bleeding was required in three patients receiving cimetidine and four receiving placebo (p greater than 0.5). Cimetidine therapy should be considered in patients more than 60 years old who present with haemorrhage from a chronic duodenal ulcer with SRH and who are at high risk of rebleeding.     

The treatment of upper digestive hemorrhages due to duodenal ulcer by direct hemostasis and vagotomy of the oxyntic cells]

Management of upper gastrointestinal haemorrhage continues to present a challenge in surgical judgment. To evaluate the incidence of rebleeding, ulcer recurrence, mortality and morbidity derived from the surgical technique, we made a prospective study in patients with active bleeding duodenal ulcer (endoscopy diagnosis in all cases), excluding patients with serious intercurrent diseases NSAIDS intake drugs and over seventy years of age. In 49 patients, oxyntic cell vagotomy with undersewing bleeding ulcer were performed in the period 1972-1984. Periodic controls were established, included clinical, radiographic and gastroduodenoscopic evaluation. Five years after operation 35 patients could be evaluated. In these cases, mortality was nil. No early rebleeding was observed. Long term endoscopic results showed only 2.85% of relapses. The results obtained in this study show that oxyntic cell vagotomy with undersewing bleeding ulcer may be a technique of choice in the treatment of bleeding duodenal ulcers and it should be more extensively used in emergency services.
