Clinical Presentation of Cases with Upper Gastro - Intestinal Bleeding.

Acute upper gastrointestinal bleeding (UGIB) is a common emergency and can be a serious condition that requires hospitalization, rapid evaluation and management. The usual presentation is hematemesis (vomiting of blood or coffee ground-like material) and/or melena (black, tarry stools) 1. UGIB occurs more commonly in men and older subjects. PUD is the most common cause of UGIB in the US accounting for about 50% of the cases, whereas in tropical country like India, esophageal varices attribute to half the cases. Esophago-Gastro-Duodenoscopy [EGD] is a primary diagnostic and therapeutic modality in the setting of UGIB. MATERIAL: Prospective study. Forty patients who have presented with frank blood or coffee ground color vomitus and/or melena were considered for this study. All patients greater than 18 years of age were included. Their clinical presentation, hemogram and endoscopic findings were analyzed. Descriptive statistical analysis has been applied. OBSERVATION: In our study, the age distribution was between 23 and 87 years. There is a male preponderance with 65 % males and 35%females. Among 40 patients,42.5%had varices, 17.5% had Peptic Ulcer Disease and12.5% had Erosive Gastritis. The other causes of UGIB include Pangastritis(10%), Mallory Weiss Tear(7.5%), Polyp(5%), Esophagitis(2.5%), Coagulopathy induced bleed(2.5%) and Carcinoma stomach(2.5%). Of the 40 cases admitted, only 3 patients (7.5%) had massive Upper GI Bleed.10 patients (25%) had moderate bleed and 27 patients (67.5%) had mild bleed. Amongst the patients with massive bleed, an important cause is esophageal varices(66.7%). A total of 21 (52.5%) patients have recovered. There was one death(2.5%) amongst the cases which was not attributed to UGIB. 14 patients(45%) has residual disease of which 42.5% were of variceal bleed. Patients with variceal bleed have undergone banding and have been asked to regularly follow up for check endoscopy and banding till their eradication. There was 1 patient of residual disease with Carcinoma stomach(2.5%) who has been initiated on chemotherapy. CONCLUSION: Hematemesis is much commoner than melena in the presentation of upper GI bleed. EGD has a diagnostic as well as therapeutic role in UGIB .In this study endoscopy provided diagnosis in 97.5% of patients. In this cross sectional study, the most common cause of upper GI bleed was esophageal varices, with alcoholic cirrhosis being the main cause of portal hypertension. Varices remain to be the most common cause of UGIB in both males and females, however, the percentage is more in males as compared to females. Varices are an important cause of massive variceal bleed.

Sending in the ViCE Squad: Evaluation and Management of Patients with Small Intestinal Bleeding.

Bleeding from the small intestine remains a clinically challenging diagnostic and therapeutic problem. It may be minor, requiring only supplemental iron treatment, to patients who have severe overt bleeding that requires multimodal intervention. This article provides an up-to-date review of the state-of-the-art of diagnosis and treatment of small intestinal bleeding.

Is coffee ground vomiting important? Findings from a large bleeding unit database and outcomes at 30 days.

OBJECTIVES: 'Coffee ground' vomiting (CGV) has classically been considered a sign of upper gastrointestinal bleeding. There is a paucity of data concerning endoscopic findings and outcomes in patients presenting with CGV. The aim of this study was to analyze endoscopic yield and 30-day outcomes in CGV patients. METHODS: Analysis was performed over the period 1992-2005 and four groups were identified: CGV alone, hematemesis alone, melena alone, and hematemesis and melena. Endoscopic yield, requirement for blood transfusion, rebleeding, and mortality rate at 30 days were calculated and compared using logistic regression analysis. RESULTS: 6054 patients (mean age 61.3 years, 3538 male) were included in the study. The hematemesis group was younger compared with the other groups. Therefore, endoscopic yield was adjusted for age and sex. CGV was associated with a significantly lower risk of gastric ulcer, duodenal ulcer, varices, gastric cancer, esophageal cancer, and Mallory-Weiss tears compared with some or all of the other groups. CGV was associated with an increased risk of esophagitis and no source was found. CGV was associated with a lower rate of blood transfusion and rebleeding (all P < 0.0001) but 30-day mortality rates were similar. CGV was less likely to require endoscopic intervention compared with the other groups (all P < 0.001). CONCLUSIONS: CGV is associated with a lower endoscopic yield, requirement for blood transfusion, rebleeding rate, and potential for intervention compared to those with hematemesis, melena or both. Mortality rates are similar suggesting a nonbleeding cause and therefore questions the role of endoscopy in CGV.

Ischemic colitis associated with acute carbon monoxide poisoning--a case report.

Carbon monoxide (CO) poisoning is common, but it has rarely been reported to cause ischemic colitis. In this case, a 34-year-old female with depression presented to an emergency department after a period of unconsciousness, with urinary and bowel incontinence, following exposure to car exhaust. Her carboxyhemoglobin level was 23%. She had metabolic acidosis. She was transferred to our facility for hyperbaric oxygen treatment, where she had intractable nausea/vomiting with abdominal pain and bright-red bleeding per rectum. She exhibited lower abdominal tenderness and hypoactive bowel sounds. Vital signs were: temperature 36.8 degrees C; blood pressure 137/ 86 mmHg; heart rate 114 beats/minute; respiratory rate 28 breaths/minute. The patient's electrocardiogram showed sinus tachycardia with T-wave inversions in leads I, aVL and V3-V6. The troponin I level peaked at 3.7 ng/ml. Echocardiogram showed a reduced ejection fraction of 30%-35%, with akinesis in the posterior lateral and distal anterior distributions. Computed tomography of the abdomen revealed diffuse colonic mural thickening, supporting mesenteric ischemia. Sigmoidoscopy showed edematous friable pale mucosa from rectum to distal sigmoid colon. Hyperbaric oxygen was deferred based on the patient's status. Over three days, the initial hematochezia progressed to melena and then resolved. Adenosine cardiac stress MRI was normal. She was transferred to the psychiatry service and discharged four days later. Four years later, she has no gastrointestinal, cardiac or cognitive problems.

Therapeutic failure with thalidomide in patients with recurrent intestinal bleeding due to angiodysplasias.

Angiodysplasias are one of the reasons of gastrointestinal bleeding, whose origin is usually due to vascular malformations. There are different types of therapies for angiodysplasia such as endoscopic, angiographic and pharmacological techniques. Among the last ones, there is little variety of effective drugs to treat the disease. We describe the therapeutic failure with thalidomide in a male with recurrent gastrointestinal bleeding due to angiodysplasias. A thorough diagnostic work-up, including gastroscopy, enteroscopy, angiography and capsule endoscopy were performed. Despite treatment with high-dose somatostatin analogues and oral iron, the patient continued bleeding. The patient was administered then thalidomide for three months with no clinical response. Thalidomide had to be withdrawn owing to adverse effects.

Una de las causas de sangrado a nivel gastrointestinal son las angiodisplasias, cuyo origen suele deberse a malformaciones a nivel vascular. Existen distintos tipos de terapias para las angiodisplasias, como son las técnicas endoscópicas, angiográficas y farmacológicas. Dentro de estas últimas existe poca variedad de fármacos efectivos para dicha patología. Se describe el fracaso terapéutico con talidomida en un varón con sangrado gastrointestinal recurrente debido a angiodisplasias. Se le realiza un diagnóstico completo, incluyendo gastroscopia, enteroscopia, angiografía y cápsula endoscópica. A pesar del tratamiento con análogos de la somatostatina a altas dosis y hierro oral, el paciente continuó sangrando. El paciente recibió talidomida durante tres meses sin respuesta clínica. La talidomida tuvo que ser retirada debido a los efectos adversos y a la falta de eficacia.

Jejunal angiodysplasia causing recurrent gastrointestinal bleeding presenting as severe anaemia and melena.

Angiodysplasia of the gastrointestinal (GI) tract consists of ectasia of the submucosal vessels of the bowel. The evaluation of such patients needs proctoscopy, colonoscopy, small bowel enema, enteroscopy, capsule enteroscopy and angiography. Capsule enteroscopy has come up as an alternative to GI enteroscopy and colonoscopy in patients with occult GI bleeding; up to 52% cases of small bowel angiodysplasia in patients with occult GI bleed with negative upper GI and colonoscopy have been reported. The use of capsule enteroscopy potentially limits the hazard of radiation exposure from angiography and is less invasive than double balloon endoscopy. The treatment options for angiodysplasias include intra-arterial vasopressin injection, selective gel foam embolisation, endoscopic electrocoagulation and injection of sclerosants, with each of these being technically demanding, and requiring centres with good access to enteroscopy technology and trained gastroenterologists. Operative intervention has been indicated for refractory bleeding or lesions in sites not accessible to endoscopic interventions.

A "rare" case of melena in a 3-year-old.

Melena is a potential sign of life-threatening upper gastrointestinal bleeding; however, there are numerous substances ingested resulting in a stool appearance similar to melena. Examples of such substances include black licorice, bismuth subsalicylate, and iron supplements. We report a case of a well-appearing 3-year-old Vietnamese girl presenting to our emergency department after 2 episodes of "black, sticky" stool. The cause of her "melena" was determined after father revealed that she had ingested 2 bowls of pork blood soup during the preceding 12 hours. This case highlights the need for a careful dietary history and cultural considerations in children presenting with what may appear to be melena.

Phase III study of pentosanpolysulfate (PPS) in treatment of gastrointestinal tract sequelae of radiotherapy.

OBJECTIVES: To evaluate the effectiveness of pentosanpolysulfate (PPS) in the treatment of gastrointestinal tract sequelae of radiotherapy. METHODS: Eligible patients were those with grade 1 to 3 radiation related proctitis, diarrhea and/or melena. At least 4 weeks had to elapse since the completion of the radiotherapy course. Patients with bleeding diathesis or ulcers, and patients receiving anticoagulants or chemotherapy were excluded. Stratification criteria included the type of sequelae (proctitis, diarrhea, melena), the severity grade and the onset (<3 months post-RT, >3 months post-RT). Patients were randomized to one of the following arms: 100 mg PPS 3 times per day (300 mg/day), 200 mg PPS 3 times per day (600 mg/day), or placebo 3 times per day. If there was no improvement in symptoms after 2 months, the protocol treatment was discontinued. If the symptoms improved or resolved, the protocol treatment was continued for additional 4 months. Patients under treatment were evaluated monthly, than every 2 to 3 months for the next 18 months. A symptom assessment questionnaire was used to measure quality of life endpoints. RESULTS: From June 1999 to March 2001 180 patients were accessioned from 34 institutions. A total of 168 were analyzable. Neither the best observed response within 3 months for the entire population, nor the response rate within sequelae category or the quality of life measures differed significantly between the 3 arms of the study. CONCLUSION: Administration of PPS has not been associated with an improvement in the clinical course of radiation related morbidity of the gastrointestinal tract.

[Gastric antral vascular ectasia:clinical presentation and therapeutic management]. / Ectasia vascular antral gástrica: presentación clínica y manejo terapéutico.

The gastric antral vascular ectasia (GAVE) or watermelon stomach is an increasingly recognized cause of persistent upper gastrointestinal bleeding, which has typical endoscopic and histological findings. This disease is most frequent in elderly women, and several associated conditions have been well established. Some patients with severe portal hypertensive gastropathy may have a GAVE like appearence. Nevertheless, a correct diagnosis is relevant in order to choose an appropiate treatment. The objective of the current study is to analyze the clinical features and treatment of a group of patients with GAVE evaluated at our Institution. A review of the current literature was also performed. Six women and three men with GAVE were admitted at the Buenos Aires British Hospital between November 1998 and January 2004. Endoscopic biopsy was performed in eight patients and was consistent with GAVE in all cases. Four patients with chronic anaemia as unique manifestation were successfully treated with iron supplements. Endoscopic treatment was performed in 4 patients, 3 of them were treated with bipolar electrocautery and 1 with argon plasma coagulation. An antrectomy was carried out in the ninth patient. The resolution of the bleeding was observed in all cases with the different therapeutics options used.

Ectasia vascular antral gástrica: presentación clínica y manejo terapéutico / Gastric antral vascular ectasia: clinical presentation and therapeutic

La ectasia vascular antral gástrica (GAVE) o watermelon stomach es un causa de hemorragia digestiva alta cuyo reconocimiento se ha incrementado, la cual posee características endoscópicas e histológicas típicas. La enfermedad es más frecuente en mujeres ancianas y varias entidades asociadas han sido bien establecidas. Si bien algunos pacientes con gastropatía asociada a la hipertensión portal pueden presentar un aspecto similar a la GAVE, la distinción resulta de interés a los fines de elegir una terapéutica apropiada. El objetivo de este estudio es analizar las características clínicas y el tratamiento de un grupo de pacientes con GAVE evaluados en nuestra institución. Asimismo, se realizóuna revisión de la bibliografía actual. Seis mujeres tres hombres con GAVE fueron admitidos en el Hospital Británico de Buenos Aires entre noviembre de 1998 y enero de 2004. Se realizó biopsia endoscópica en ocho pacientes, siendo consistente con GAVE en todos los casos. Cuatro pacientes con anemia crónica como única manifestación fueron exitosamente tratados con suplementos de hierro. Se realizó tratamiento endoscópico en cuatro pacientes, tres de ellos con electrocauterio bipolar y uno con coagulación con argón plasma. El paciente restante fue sometido a antrectomía. Se observó resolución del sangrado en todos los casos, más allá de la terapéutica instituída.

Combined diagnostic imaging of intestinal involvement in Henoch-Schönlein purpura.

The case of a 39-year-old male patient with symptoms of persistent abdominal pain and melena, affected by Henoch-Schönlein purpura, is reported. Abdominal CT was requested. The examination was justified by the fact that symptoms could be correlated with other pathological conditions (volvulus, neoplasms, Chron's disease, etc.) which had to be excluded. For optimum study of the abdominal wall, correct preparation and the use of oral contrast agents were required. From the analysis of CT findings, in particular loop thickening with stratified density, the increased density of mesenteric fat and the presence of fluid among loops led to the radiological diagnosis of intestinal involvement in Henoch-Schönlein purpura. Other imaging procedures (double contrast enema, sonography, Doppler US, MRI) now used in the study of intestinal loops, are examined.

[Granulocytic sarcoma of the colon in chronic myelomonocytic leukemia].

A 59-year-old man with a six-month history of chronic myelomonocytic leukemia (CMML) was admitted to the Kitasato University Hospital because of melena in September 2000. Colonofiberscopy and barium enema demonstrated an ulcerated tumorous lesion in the transverse colon. The histopathologic findings of the ulcer bed revealed diffuse infiltration of granulocytes at each stage of differentiation. The diagnosis of granulocytic sarcoma (GS) was made. Surgical resection was not indicated, because thrombocytopenia was hardly improved enough to allow surgery despite repetitive transfusion of platelet concentrates. CMML developed to refractory anemia with excess of blast in transformation in February 2001. Two courses of low dose cytarabine plus aclarubicin were ineffective on the GS in spite of a decrease in the peripheral blood blasts. Progression to acute myeloid leukemia eventually broke out, in July 2001. The patient died of leukemia complicated with pneumonia and intestinal obstruction. At present, nine cases of GS in the colon have been reported. However, these cases did not include CMML. This is the first report describing GS in the colon associated with CMML.

[Recurrent sanguineous and mucous diarrhea and spasms in a 46-year-old woman--manifestation of endometriosis in the colon sigmoideum]. / Rezidivierende schleimig-blutige Diarrhöen und Tenesmen bei einer 46-jährigen Frau - Manifestation einer Endometriose im Colon sigmoideum.

Intestinal endometriosis is the most frequent extragenital manifestation of this disease. Sometimes patients even present with acute bowel obstruction. We report on a 46-year-old woman complaining about recurrent sanguineous and mucous diarrhea and spasms for several years. Colonoscopy showed a stenosis in the sigmoid colon without macroscopically visible alterations of the mucosa. Computertomography, ultrasound and barium contrast enema did not provide us with further information about the origin of the stenosis. Biopsies out of the mucosa at the stenosis showed typical endometriosis tissue. After starting a conservative therapy with GnRH-agonist gosereline the patient became completely free of symptoms. The coincidence of endometriosis and M. Crohn has to be taken into consideration. Therapy planning should include a close co-operation with gynaecologists and surgeons to transfer the patient to surgical intervention when needed.

Diagnostic considerations in evaluation of patients presenting with melena and nondiagnostic esophagogastroduodenoscopy.

Proper evaluation of patients with melena and nondiagnostic esophagogastroduodenoscopy is comparatively undefined. We sought to determine the percentage of patients with melena and nondiagnostic upper endoscopy and assess the yield of further evaluation. Of 209 patients presenting with melena, 180 underwent esophagogastroduodenoscopy as the initial study, which was nondiagnostic in 43 cases (24%). Further evaluation was pursued in 30. A presumed source of melena was found in 11 patients (37%), identified by colonoscopy in seven, bleeding scan in three, and barium enema plus flexible sigmoidoscopy in one. Nearly all such defined cases originated from the right colon. Small bowel contrast studies, flexible sigmoidoscopy of barium enema alone, and angiography failed to reveal a source. Our findings suggest that many (24%) patients presenting with melena will have nondiagnostic upper endoscopy; further evaluation reveals a potential source in 37% of this group, with the right colon being the most likely location of pathology; and colonoscopy is the test of choice in this cohort.

Recurrent intussusception. Risks and features.

OBJECTIVE: To determine the risk factors associated with recurrent intussusception (RI) and to characterize the timing, features, and complications of RI. DESIGN: Retrospective chart review. SETTING: Children's Hospital and Medical Center, Seattle, Wash. PARTICIPANTS: All patients with a diagnosis of intussusception who underwent barium enema as treatment for reduction between October 1, 1979 and December 31, 1990. Children with RI (N = 23, seven with two or more recurrent episodes) were classified as the case group; children with a single intussusception (N = 234), controls. RESULTS: There were no statistically significant differences in age, sex, race, symptoms, duration of symptoms, or results of the physical examination between the case group and controls. Reduction of the initial intussusception by a barium enema occurred in 96% of patients in the case group vs 62% of the controls (odds ratio, 13.50; 95% confidence intervals, 2.10 to 563.4; P = .003). Only one of 33 episodes of RI followed an operative reduction. In comparing the first recurrent episode with the initial episode, there was a significant reduction in the proportion of patients presenting with lethargy (0% vs 30%; Fisher Exact Test, P = .009) or blood in the stool (5% vs 52%; P < .002) and a drop in the median duration of symptoms from 20 to 6 hours. CONCLUSIONS: Recurrent intussusception cannot be predicted by presenting features or symptoms; operative reduction due to a failed reduction by a barium enema reduces the risk of RI; and patients with RI have fewer symptoms with a shorter duration.

[The endoscopic diagnosis of rectorrhagias]. / Diagnostica endoscopica delle rettorragie.

The diagnosis of bleeding of gastrointestinal low tract is still a very controversial subject. At the Service of Digestive Endoscopy of Popoli (PE) Hospital, in a period of 4 years, 2074 colonoscopies have been effected. In 640 cases, that is 30.8%, the indication for the exam was suggested by rectal bleeding. In the 566 patients examined for minor rectal bleeding, the most frequent lesions were: haemorrhoids (35.3%), polyps (15.2%), malignant neoplastic disease (9.3%). In all active rectal haemorrhages (14 massive, 41 medium) an urgent colonoscopy has been carried out with a percentage of success of 90%; in the 20 cases of unexplained melena, colonoscopy has not led to a diagnosis; in the 14 patients with unexplained anemia, colonoscopy has shown 2 carcinomas, whereas in the 5 cases with occult blood in stools it has been diagnostic in the percentage of 60%. We have ascertained that, when barium enema was effected before colonoscopy, the diagnostic agreement between the two examinations was only of 21.4 (9/42); on the contrary there was an agreement of 95% when colonoscopy was effected before barium enema. In accordance with Siewert and Blum (25), Ottenjann (24) and Farrands (42), we believe that colonoscopy should be considered the main examination after either major or minor rectal bleeding, because it is a quick and safe investigation with high diagnostic specificity and sensitivity. We refuse William's position (41), because, even in presence of haemorrhoids or anal fissures, the colon must be studied as a whole, especially in a period when neoplastic disease of this tract of intestine is considerably increasing.(ABSTRACT TRUNCATED AT 250 WORDS)

A rare source of occult gastrointestinal bleeding: jejunal filiae secondary to metastatic lung carcinoma.

A case of occult gastrointestinal bleeding due to jejunal metastases of a primary lung carcinoma in a 53-year-old man is reported. When after healing of a large gastric ulcer melena persisted, a subsequently performed double contrast enema of the small bowel revealed evidence of several jejunal tumors. This was confirmed by angiography of the superior mesenteric artery and computed tomography of the abdomen. After resection of the tumor-bearing jejunal loop, histological evaluation revealed metastases secondary to a large-cell bronchogenic carcinoma which had been resected 1 year previously.
