A patient with a jejunal leiomyoblastoma presented with lower gastrointestinal haemorrhage, a most unusual occurrence according to the literature. The provisional diagnosis was made by arteriography and confirmed pathologically. The characteristics of these tumours are analyzed and the management discussed.
A case of porto-cholecysto-duodenal fistula which caused a severe upper gastrointestinal haemorrhage is presented. The difficulties involved in diagnosis and surgical treatment are discussed.
In this prospective study for pharmacotherapy of non varicial upper gastrointestinal haemorrhage eight therapy groups were examined. The efficacy of the most important drugs for ulcus disease was considered. The drugs were used alone and in combination. The results indicated no favourable effect of one preparation (Cimetidine, Pirenzepine, Ranitidine). Significant benefit for the long time healing rate was noted among the combination therapies, especially with Sucralfate, which was not used alone.
The urea/creatinine-ratio has been proposed as an instrument for differentiating upper from lower gastrointestinal haemorrhages. The predictability of this method was investigated in 105 cases with the source of bleeding to be in the upper gastrointestinal tract and in 31 cases in the lower gastrointestinal tract. Determination of the urea/creatinine-ratio predicted the site of bleeding in only 60% of the patients. The use of the ratio in diagnostic decision making would increase the number of unnecessary colonoscopies. Thus, the urea/creatinine-ratio does not appear to be clinically useful in predicting the localization of a gastrointestinal bleeding with adequate certainty.
Data of 3014 patients with nonvariceal upper gastrointestinal bleeding were retrospectively evaluated in county Vas between 1984 and 1995. The annual incidence of bleeding increased progressively in this period. In this change the role of nonsteroidal antiinflammatory drugs in questionable, because in the investigated period the sale of these drugs decreased, although the purchase of oxicame, one of this drug-group associating with higher risk for bleeding increased. The risk of bleeding enhanced with ageing that can be explained by higher rate of Helicobacter pylori infection, by the greater consumption of nonsteroidal antiinflammatory drugs and by the more frequent serious concomitant diseases in elderly age. The risk of bleeding in males proved to be higher than in females, the frequency of bleeding in men was twice as much as it could be expected according to the sex rate of the peptic lesions. Their results concerning the reduction of mortality underline the importance of the early endoscopic diagnosis and therapy.
OBJECTIVE: To develop an outcome prediction tool (BLEED: ongoing bleeding, low systolic blood pressure, elevated prothrombin time, erratic mental status, unstable comorbid disease) for clinical use in patients with either acute upper or acute lower gastrointestinal (GI) hemorrhage. DESIGN: A cohort study. SETTING: Barnes Hospital and Jewish Hospital, two private university-affiliated teaching hospitals in St. Louis, MO. PATIENTS: Four hundred sixty-five patients with either acute upper or acute lower GI hemorrhage admitted from the emergency department. INTERVENTIONS: Admission of patients to the intensive care unit or hospital ward was determined by emergency department physicians, without use or knowledge of BLEED criteria. Patients meeting any BLEED criteria at their initial assessment in the emergency department were classified as "high-risk." All other patients were classified as "low-risk." MEASUREMENTS AND MAIN RESULTS: The main outcome measure was the occurrence of an inhospital complication, defined as recurrent GI hemorrhage, surgery to control the source of hemorrhage, and hospital mortality. Patients classified as high-risk had significantly greater rates of inhospital complications at both Barnes Hospital (relative risk, 2.47; 95% confidence interval, 1.38 to 4.44; p < .001) and Jewish Hospital (relative risk, 8.94; 95% confidence interval, 3.92 to 20.41; p < .001) compared with patients classified as low-risk. Patients classified as high-risk at either hospital were significantly more likely to develop additional organ system derangements, require a greater number of transfused units of packed red blood cells, and have longer hospital stays compared with patients classified as low-risk (p < .006). The BLEED classification also identified a greater frequency of intensive care admission for both low-risk (RR, 4.21; 95% Cl, 2.24 to 7.89) and high-risk (relative risk, 1.58; 95% confidence interval, 1.23 to 2.02) patients at Barnes Hospital compared with those patients at Jewish Hospital, although no beneficial effects on patient outcome were reported. CONCLUSIONS: The BLEED classification, applied at initial emergency department evaluation and before admission, predicts hospital outcomes for patients with acute upper or lower GI hemorrhage. This outcome prediction tool also identified variations in intensive care utilization between two hospitals.
COX-2 inhibitors are a new class of nonsteroidal anti-inflammatory drugs with a reported benefit of less gastric and duodenal ulceration and hemorrhage. We describe a 67-year-old man taking a higher than usual dose of celecoxib (Celebrex) for osteoarthritis with resultant gastric erosions, ulceration, and a significant gastrointestinal (GI) hemorrhage.
PURPOSE: To find out if digital subtraction angiography (DSA) has a different diagnostic power than conventional cut-film angiography in investigating acute lower gastrointestinal (GI) hemorrhage. MATERIALS AND METHODS: Retrospective analysis of two cohorts of patients investigated by angiography for acute lower GI hemorrhage was performed. One group of patients treated at one center ("hospital H") underwent conventional angiography. The other patients, treated at another center ("hospital G"), were investigated exclusively by DSA. The groups were compared for demographic characteristics, etiology, and bleeding parameters. The diagnostic power of both angiographic modalities was compared and statistically analyzed. RESULTS: Fifty-five lower GI hemorrhages investigated by conventional cut-film angiography and 53 cases studied by DSA were included. Both study groups had statistically similar demographic and bleeding characteristics. Overall sensitivity, specificity, and positive and negative predictive values of cut-film angiography for localizing the lower GI bleeding were 62%, 73%, 86%, and 42%, whereas, for DSA, the respective values were 60%, 100%, 100%, and 24% (Z-test P values were.78,.02,.03, and.16). CONCLUSIONS: DSA is as sensitive as conventional cut-film angiography for localizing acute lower GI bleeding. If a lesion is found, the chance that it will be the bleeding source is higher with DSA than with conventional angiography.
Seventy-six patients clinically suspected of having lower gastrointestinal bleeding were studied by scintigraphy utilizing red blood cells labeled in vitro with technetium Tc 99m. Sixteen patients required emergency surgery; bleeding was accurately localized in 15 (94%). One patient (6%) had a normal scan. A 20-month mean follow-up of the 16 patients showed no recurrent bleeding. Of 60 patients not requiring emergency surgery, bleeding was localized in 11, but the bleeding ceased. Forty-nine of the 60 patients had normal scans and had no further hemorrhaging during hospitalization. A 21-month mean follow-up of 38 of the 49 patients showed no further bleeding episodes or surgical procedures in 29 patients; however, eight patients required surgical procedures, including seven for gastrointestinal malignancies. Scanning of red blood cells labeled in vitro with 99mTc is accurate and efficacious in localization of bleeding sites that require emergency surgery for lower gastrointestinal hemorrhage.
The coincidence of aortic valve stenosis and cryptogenic gastrointestinal bleeding usually from angiodysplasia of the cecum and ascending colon has been called Heyde syndrome. The pathophysiologic link between both remains unclear and may be due to subtle changes in plasmatic coagulation. There are some statistic and numerous casuistic reports, and recently the existence of the syndrome has been questioned. We describe two cases of aortic valve stenosis and cryogenic gastrointestinal bleeding in which bleeding subsided after replacement with a bioprosthesis. We give an overview of the current literature.
A 71-year-old man was admitted to the emergency unit with upper gastrointestinal bleeding, due to a gastric lipoma, which was controlled with conservative measures. Endoscopy and computed tomography revealed a 4-cm submucosal mass located in the posterior wall of gastric antrum. The patient underwent an elective laparoscopic transgastric resection of the lipoma and discharged on postoperative day 6. Gastric lipomas are uncommon tumors that can be incidentally found. They produce symptoms similar to peptic ulcer disease and can lead to obstruction. Gastric lipomas, which may lead to life-threatening complications such as bleeding, can be safely and reliably treated by laparoscopic transgastric resection.
OBJECTIVES: We hypothesized that early intervention in patients with lower gastrointestinal bleeding (LGIB) would improve outcomes and therefore conducted a prospective randomized study comparing urgent colonoscopy to standard care. METHODS: Consecutive patients presenting with LGIB without upper or anorectal bleeding sources were randomized to urgent purge preparation followed immediately by colonoscopy or a standard care algorithm based on angiographic intervention and expectant colonoscopy. RESULTS: A total of 50 patients were randomized to each group. A definite source of bleeding was found more often in urgent colonoscopy patients (diverticula, 13; angioectasia, 4; colitis, 4) than in the standard care group (diverticula, 8; colitis, 3) (the odds ratio for the difference among the groups was 2.6; 95% CI 1.1-6.2). In the urgent colonoscopy group, 17 patients received endoscopic therapy; in the standard care group, 10 patients had angiographic hemostasis. There was no difference in outcomes among the two groups-including: mortality 2%versus 4%, hospital stay 5.8 versus 6.6 days, ICU stay 1.8 versus 2.4 days, transfusion requirements 4.2 versus 5 units, early rebleeding 22%versus 30%, surgery 14%versus 12%, or late rebleeding 16%versus 14% (mean follow-up of 62 and 58 months). CONCLUSION: Although urgent colonoscopy identified a definite source of LGIB more often than a standard care algorithm based on angiography and expectant colonoscopy, the approaches are not significantly different with regard to important outcomes. Thus, decisions concerning care for patients with acute LGIB should be based on individual experience and local expertise.
Thirty-six pancreatic patients with massive gastrointestinal bleeding have now been identified as having pancreaticoduodenal and gastroduodenal artery aneurysms as causative. In the past decade, seven of the patients have been encountered at the authors' institution and seven presented in the literature. Of these 14, there was a predilection for men (85%) with an average age of 48.1 years, who had complications of pancreatitis (75%), that is, abscess or pseudocyst. Eleven of these patients underwent surgery with an 81 per cent survival rate. Previous reports had shown a 47 per cent survival rate in 19 similar patients. Embolization of the aneurysm was attempted in four patients with two successes. The authors believe that early diagnosis by arteriography and early operative intervention were responsible for the improved survival. A high index of suspicion in this patient population is crucial for early diagnosis and improvement in survival.
A retrospective study of 68 patients with acute upper gastrointestinal bleeding (excluding bleeding from esophageal varices) revealed that all patients had emergency surgery. The factors influencing the mortality and the recurrent bleeding have been sought. The overall mortality was 29.5%. Age of patients and type of surgical procedure did not affect the mortality raate, while chronicity of lesions and their duodenal location had a favourable influence. Most deaths were due to hypovolemic shock and its complications. Gastric resection with vagotomy is the operation of choice for control of bleeding. The authors present a brief review of the literature and stress the importance of early diagnosis and resuscitative measures, as well as the need for aggressive surgical intervention.
Mucosal and vascular changes in the lower gastrointestinal tract occur commonly in patients with portal hypertension. Portal enteropathy, however, is usually asymptomatic, though occasionally clinically significant for chronic gastrointestinal bleeding. Massive hemorrhage has only rarely been described and its management is controversial. Even though more effective non-operative treatments are now available, an emergency porta-systemic shunt procedure remains an important option for selected patients. We report on two cases of massive lower gastrointestinal bleeding from portal hypertensive enteropathy secondary to post-viral cirrhosis.
In most cases (80%), acute lower gastrointestinal bleeding stops spontaneously, but rebleeding is frequent (25%). The intensity and quality of the bleeding--hematochezia, melena, or occult bleeding--determines the diagnostic and therapeutic strategy (endoscopic evaluation of the upper and lower gastrointestinal tract, mesenteric angiography, scintigraphy, enteroscopy, capsule endoscopy) and its urgency. Acute lower gastrointestinal bleeding can mostly be treated conservatively or by endoscopic interventions (injection therapy, clip application, coagulation and ligation methods). Severe hemorrhage can render colonoscopy and the identification of the bleeding source technically difficult. Emergency operations are only indicated when patients with severe hemorrhage cannot be stabilized by interventional endoscopy or angiography with selective embolization.
BACKGROUND: Hemorrhage from the excluded gastric segment or duodenum after gastric bypass is an uncommon late complication and poses both diagnostic and therapeutic difficulties. We describe 4 cases of late gastrointestinal (GI) hemorrhage after gastric bypass. METHODS: 4 patients who underwent previous Roux-en-Y gastric bypass (RYGBP) presented for management of severe GI hemorrhage. Their history, diagnostic work-up, management, and surgical pathology are reviewed. RESULTS: In all 4 patients, preoperative diagnostic evaluation including nuclear scintigraphy, endoscopy, and angiography failed to localize the source of bleeding. Intraoperative endoscopy of the gastric remnant and subtotal gastrectomy were performed in all 4 patients. The mean time interval between RYGBP operation and gastrectomy was 15.5 years (range 13-17 years). In 3 of 4 patients, the source of bleeding was documented on pathologic examination of the resected gastric remnant and duodenum. At a mean follow-up of 15 months, none of the patients developed recurrent GI hemorrhage. CONCLUSION: GI hemorrhage after RYGBP can be a diagnostic and therapeutic dilemma. Intraoperative endoscopy of the excluded stomach and subtotal gastrectomy should be considered when the source of bleeding is not identified by conventional diagnostic techniques.
PURPOSE: To evaluate the clinical use of (99m)Tc red blood cell imaging (RBC imaging) in patients presenting with acute lower gastrointestinal (GI) bleeding and negative endoscopy and multislice computed tomography (MSCT) findings. PATIENTS AND METHODS: In 31 consecutive patients with acute lower GI bleeding in whom the endoscopy findings were negative or the procedure was not feasible, dual-phase MSCT of the abdomen was performed [collimation 4x1 mm (arterial phase), 4x2.5 mm (venous phase)]. MSCT was followed by a (99m)Tc red blood cell scan in patients in whom no active bleeding was visible by CT. Images were created within 24 h after administration of the tracer, depending on the clinical symptoms. The results of the imaging modalities were correlated with clinical course and surgical treatment. RESULTS: In 20 of 31 patients MSCT showed no active bleeding and a (99m)Tc red blood cell scan was performed. In 8 of 20 patients RBC imaging was also negative. Of these eight patients five were stable and did not require further diagnostic work-up; in the other three bleeding persisted and these patients required surgical treatment. In 12 of 20 patients active bleeding was demonstrated using a (99m)Tc red blood cell scan. Of 12 patients with positive RBC scintigraphy findings, 8 underwent surgery, where the site of bleeding was confirmed. CONCLUSION: In patients with acute lower GI bleeding with negative or nondiagnostic endoscopy or MSCT findings, (99m)Tc red blood cell imaging is a useful tool in an emergency algorithm, improving the overall bleeding detection rate.
