Improving primary prophylaxis of variceal bleeding by adapting therapy to the clinical stage of cirrhosis. A competing-risk meta-analysis of individual participant data.

BACKGROUND & AIMS: Non-selective ß-blockers (NSBBs) and endoscopic variceal-ligation (EVL) have similar efficacy preventing first variceal bleeding. Compensated and decompensated cirrhosis are markedly different stages, which may impact treatment outcomes. We aimed to assess the efficacy of NSBBs vs EVL on survival in patients with high-risk varices without previous bleeding, stratifying risk according to compensated/decompensated stage of cirrhosis. METHODS: By systematic review, we identified RCTs comparing NSBBs vs EVL, in monotherapy or combined, for primary bleeding prevention. We performed a competing-risk, time-to-event meta-analysis, using individual patient data (IPD) obtained from principal investigators of RCTs. Analyses were stratified according to previous decompensation of cirrhosis. RESULTS: Of 25 RCTs eligible, 14 failed to provide IPD and 11 were included, comprising 1400 patients (656 compensated, 744 decompensated), treated with NSBBs (N = 625), EVL (N = 546) or NSBB+EVL (N = 229). Baseline characteristics were similar between groups. Overall, mortality risk was similar with EVL vs. NSBBs (subdistribution hazard-ratio (sHR) = 1.05, 95% CI = 0.75-1.49) and with EVL + NSBBs vs either monotherapy, with low heterogeneity (I2 = 28.7%). In compensated patients, mortality risk was higher with EVL vs NSBBs (sHR = 1.76, 95% CI = 1.11-2.77) and not significantly lower with NSBBs+EVL vs NSBBs, without heterogeneity (I2 = 0%). In decompensated patients, mortality risk was similar with EVL vs. NSBBs and with NSBBs+EVL vs. either monotherapy. CONCLUSIONS: In patients with compensated cirrhosis and high-risk varices on primary prophylaxis, NSBBs significantly improved survival vs EVL, with no additional benefit noted adding EVL to NSBBs. In decompensated patients, survival was similar with both therapies. The study suggests that NSBBs are preferable when advising preventive therapy in compensated patients.

Outcomes of patients with ischemic colitis causing severe hematochezia managed medically or surgically.

PURPOSE: To compare short- and long-term outcomes of hospitalized patients with ischemic colitis (IC) presenting with severe hematochezia and treated medically or colectomy and also those with inpatient vs. outpatient start of hematochezia. METHODS: A retrospective analysis of prospectively collected data for IC patients hospitalized for severe hematochezia from two teaching hospitals was done from 1994 to 2020, with the diagnosis of IC made colonoscopically and confirmed histologically. RESULTS: Ninety-seven patients initially all had medical management for IC. Seventy-two (74.2%) were stable and had no further bleeding; 17 (17.5%) had colon resection; and 8 were critically ill and not surgical candidates. Surgical patients and non-surgical candidate had higher comorbidity scores; received more red blood cell (RBC) transfusion (median (IQR) 5 (3-10) vs. 4.5 (3-6.5) vs. 1 (0-4) units, p < 0.001); had significantly longer hospital and ICU days; had higher severe complication rates (35.3% vs. 100%. vs. 5.6%, p < 0.001); and had higher 30-day all-cause mortality rates (23.5% vs. 87.5% vs. 0, p < 0.001). Inpatients developing IC hemorrhage had more RBC transfusions, more complications, longer hospital stays, and higher mortality than patients whose IC bleeding started as outpatients. CONCLUSIONS: The majority of IC patients hospitalized for severe hematochezia were successfully treated medically. Patients who were not surgical candidate had the highest rates of severe complications and mortality. Surgical patients and those who were not surgical candidate had worse outcomes than the medical group. Patients with inpatient start of bleeding from IC had significantly worse outcomes than those with outpatient start of bleeding.

Acute gastrointestinal bleeding: proposed study outcomes for new randomised controlled trials.

BACKGROUND: Acute gastrointestinal bleeding (GIB) remains a common cause of hospitalisation. However, interpretation and comparisons of published studies in GIB have been hampered by disparate study methodology. AIMS: To make recommendations about outcome measures to be used in future randomised controlled trials (RCTs) of patients with acute bleeding from any GI source (nonvariceal UGI, variceal, small bowel, or colon) and suggest new RCTs in acute GIB for future peer-reviewed funding. METHODS: As part of a National Institutes of Health conference entitled "Hemostatic Outcomes in Clinical Trials", a group of GIB experts performed targeted critical reviews of available evidence with the goal of proposing a bleeding outcome that could potentially be applied to different disciplines. In addition, the panel sought to develop a clinically meaningful primary endpoint specifically for acute GIB, potentially allowing a more contemporary regrouping of clinically relevant outcomes. RESULTS: The primary endpoint proposed was a composite outcome of further bleeding within 30 days after randomisation leading to red blood cell transfusion, urgent intervention (repeat endoscopy; interventional radiology or surgery), or death. Secondary outcomes may include the individual components of the primary outcome, length of hospitalisation, serious adverse events, and health care resource utilisation. CONCLUSION: The proposed endpoint may help move the GIB field forward by focusing on the most clinically relevant outcomes for patients with acute GIB of all types and informing study design and importance of sample size determination for future RCTs in GIB.

Laparotomy and intraoperative enteroscopy for obscure gastrointestinal bleeding before and after the era of video capsule endoscopy and deep enteroscopy: A tertiary center experience.

BACKGROUND: To evaluate roles of intraoperative endoscopy (IOE) in management of severe obscure GI bleeding (OGIB) before vs. after introduction of video capsule endoscopy (VCE) and deep enteroscopy (DE). METHODS: We retrospectively reviewed prospectively collected data of patients undergoing IOE for severe OGIB in a tertiary referral center. RESULTS: 52 patients had laparotomy/IOE for OGIB, 11 pre and 41 post VCE/DE eras. In the pre VCE/DE era, 36.4% (4/11) had preoperative presumptive diagnoses while in the post VCE/DE era presumptive diagnoses were made in 48.8% (20/41) (p = 0.18). Preoperative evaluation led to correct diagnoses in 18.2% (2/11) in the pre and 51.2% (21/41) in the post VCE/DE era (p = 0.09). Vascular lesions and ulcers were the most common diagnoses, but rebleeding was common. No rebleeding was found among patients with tumors, Meckel's diverticulum, and aortoenteric fistula. CONCLUSIONS: Presumptive diagnoses in the post VCE/DE era were usually accurate. If VCE or DE are negative, the probability of negative IOE is high. Patients with tumors and Meckel's diverticulum were the best candidates for IOE.

Doppler Endoscopic Probe Monitoring of Blood Flow Improves Risk Stratification and Outcomes of Patients With Severe Nonvariceal Upper Gastrointestinal Hemorrhage.

BACKGROUND & AIMS: For 4 decades, stigmata of recent hemorrhage in patients with nonvariceal lesions have been used for risk stratification and endoscopic hemostasis. The arterial blood flow that underlies the stigmata rarely is monitored, but can be used to determine risk for rebleeding. We performed a randomized controlled trial to determine whether Doppler endoscopic probe monitoring of blood flow improves risk stratification and outcomes in patients with severe nonvariceal upper gastrointestinal hemorrhage. METHODS: In a single-blind study performed at 2 referral centers we assigned 148 patients with severe nonvariceal upper gastrointestinal bleeding (125 with ulcers, 19 with Dieulafoy's lesions, and 4 with Mallory Weiss tears) to groups that underwent standard, visually guided endoscopic hemostasis (control, n = 76), or endoscopic hemostasis assisted by Doppler monitoring of blood flow under the stigmata (n = 72). The primary outcome was the rate of rebleeding after 30 days; secondary outcomes were complications, death, and need for transfusions, surgery, or angiography. RESULTS: There was a significant difference in the rates of lesion rebleeding within 30 days of endoscopic hemostasis in the control group (26.3%) vs the Doppler group (11.1%) (P = .0214). The odds ratio for rebleeding with Doppler monitoring was 0.35 (95% confidence interval, 0.143-0.8565) and the number needed to treat was 7. CONCLUSIONS: In a randomized controlled trial of patients with severe upper gastrointestinal hemorrhage from ulcers or other lesions, Doppler probe guided endoscopic hemostasis significantly reduced 30-day rates of rebleeding compared with standard, visually guided hemostasis. Guidelines for nonvariceal gastrointestinal bleeding should incorporate these results. ClinicalTrials.gov no: NCT00732212 (CLIN-013-07F).

Origin, Clinical Characteristics and 30-Day Outcomes of Severe Hematochezia in Cirrhotics and Non-cirrhotics.

BACKGROUND: The sites of origin, causes and outcomes of severe hematochezia have not been compared between cirrhotics and non-cirrhotics. In cirrhotics versus non-cirrhotics presenting with severe hematochezia, we aimed at (1) identifying the site and etiology of gastro-intestinal bleeding and independent predictors of bleeding from the upper gastrointestinal tract versus small bowel or the colon, (2) comparing 30-day clinical outcomes, and (3) proposing an algorithm for management of severe hematochezia. METHODS: In this cohort study from two university-based medical centers, 860 consecutive patients with severe hematochezia admitted from 1995 to 2011 were prospectively enrolled with 160 (18.6 %) cirrhotics. We studied (a) general clinical and laboratory characteristics of cirrhotics versus non-cirrhotics, (b) predictors of bleeding sites in each patient group by multiple variable regression analysis, and compared (c) 30-day outcomes, including rebleeding, surgery and deaths. RESULTS: Cirrhosis independently predicted an upper gastrointestinal source of bleeding (OR 3.47; 95 % CI 2.01-5.96) as well as history of hematemesis, melena in the past 30 days, positive nasogastric aspirate, prior upper gastrointestinal bleeding or use of aspirin or non-steroidal anti-inflammatory. The most prevalent diagnoses were esophageal varices (20 %) in cirrhotics and colon diverticular bleeding (27.1 %) in non-cirrhotics. Thirty-day rates of rebleeding, surgical interventions and deaths were 23.1 versus 15 % (P = 0.01), 14.4 versus 6.4 % (P < 0.001), and 17.5 versus 4.1 % (P < 0.001), in cirrhotics versus non-cirrhotics, respectively. CONCLUSIONS: Cirrhosis predicted an upper gastrointestinal site of bleeding in patients presenting with severe hematochezia. The 30-day rates of rebleeding, surgery, and death were significantly higher in cirrhotics than in non-cirrhotics.

Doppler endoscopic probe as a guide to risk stratification and definitive hemostasis of peptic ulcer bleeding.

BACKGROUND AND AIMS: For more than 4 decades endoscopists have relied on ulcer stigmata for risk stratification and as a guide to hemostasis. None used arterial blood flow underneath stigmata to predict outcomes. For patients with severe peptic ulcer bleeding (PUB), we used a Doppler endoscopic probe (DEP) for (1) detection of blood flow underlying stigmata of recent hemorrhage (SRH), (2) quantitating rates of residual arterial blood flow under SRH after visually directed standard endoscopic treatment, and (3) comparing risks of rebleeding and actual 30-day rebleed rates for spurting arterial bleeding (Forrest [F] IA) and oozing bleeding (F IB). METHODS: Prospective cohort study of 163 consecutive patients with severe PUB and different SRH. RESULTS: All blood flow detected by the DEP was arterial. Detection rates were 87.4% in major SRH-spurting arterial bleeding (F IA), non-bleeding visible vessel (F IIA), clot (F IIB)-and were significantly lower at 42.3% (P < .0001) for an intermediate group of oozing bleeding (F IB) or flat spot (F IIC). For spurting bleeding (F IA) versus oozing (F IB), baseline DEP arterial flow was 100% versus 46.7%, residual blood flow detected after endoscopic hemostasis was 35.7% versus 0%, and 30-day rebleed rates were 28.6% versus 0% (all P < .05). CONCLUSIONS: (1) For major SRH versus oozing or spot, the arterial blood flow detection rate by the DEP was significantly higher, indicating a higher rebleed risk. (2) Before and after endoscopic treatment, spurting (F IA) PUB had significantly higher rates of blood flow detection than oozing (F IB) PUB and a significantly higher 30-day rebleed rate. (3) The DEP is recommended as a new endoscopic guide with SRH to improve risk stratification and potentially definitive hemostasis for PUB.

Comparison of Three Risk Scores to Predict Outcomes of Severe Lower Gastrointestinal Bleeding.

BACKGROUND AND AIMS: Improved medical decisions by using a score at the initial patient triage level may lead to improvements in patient management, outcomes, and resource utilization. There is no validated score for management of lower gastrointestinal bleeding (LGIB) unlike for upper gastrointestinal bleeding. The aim of our study was to compare the accuracies of 3 different prognostic scores [Center for Ulcer Research and Education Hemostasis prognosis score, Charlson index, and American Society of Anesthesiologists (ASA) score] for the prediction of 30-day rebleeding, surgery, and death in severe LGIB. METHODS: Data on consecutive patients hospitalized with severe gastrointestinal bleeding from January 2006 to October 2011 in our 2 tertiary academic referral centers were prospectively collected. Sensitivities, specificities, accuracies, and area under the receiver operator characteristic curve were computed for 3 scores for predictions of rebleeding, surgery, and mortality at 30 days. RESULTS: Two hundred thirty-five consecutive patients with LGIB were included between 2006 and 2011. Twenty-three percent of patients rebled, 6% had surgery, and 7.7% of patients died. The accuracies of each score never reached 70% for predicting rebleeding or surgery in either. The ASA score had a highest accuracy for predicting mortality within 30 days (83.5%), whereas the Center for Ulcer Research and Education Hemostasis prognosis score and the Charlson index both had accuracies <75% for the prediction of death within 30 days. CONCLUSIONS: ASA score could be useful to predict death within 30 days. However, a new score is still warranted to predict all 30 days outcomes (rebleeding, surgery, and death) in LGIB.

Natural history of definitive diverticular hemorrhage based on stigmata of recent hemorrhage and colonoscopic Doppler blood flow monitoring for risk stratification and definitive hemostasis.

BACKGROUND AND AIMS: Few prospective reports describe the short-term natural history of colon diverticular hemorrhage based on stigmata of recent hemorrhage, and none include blood flow detection for risk stratification or as a guide to definitive hemostasis. Our purposes were to report the 30-day natural history of definitive diverticular hemorrhage based on stigmata and to describe Doppler probe blood flow detection as a guide to definitive hemostasis. METHODS: Different cohorts of patients with severe diverticular bleeding and stigmata on urgent colonoscopy are reported. For 30-day natural history, patients were treated medically. If severe rebleeding occurred, they had surgical or angiographic treatment. We report natural history with major stigmata (active bleeding, visible vessel, or adherent clot) and no stigmata or flat spots after clots were washed away. We also report Doppler probe detection of arterial blood flow underneath stigmata before and after hemostasis in a recent cohort. RESULTS: For natural history, patients with major stigmata treated medically had 65.8% (25/38) rebleeding rates, and 44.7% (17/38) had intervention for hemostasis. Patients with spots or clean bases had no rebleeding. A Doppler probe detected arterial blood flow in 92% of major stigmata--none after hemostasis--and there was no rebleeding. CONCLUSIONS: (1) Patients with major stigmata treated medically had high rates of rebleeding and intervention for hemostasis. (2) Patients with clean diverticula or only flat spots had no rebleeding. (3) High rates of arterial blood flow were detected under major stigmata with a Doppler probe, but with obliteration by hemostasis no rebleeding occurred.

Epistaxis in end stage liver disease masquerading as severe upper gastrointestinal hemorrhage.

AIM: To describe the prevalence, diagnosis, treatment, and outcomes of end stage liver disease (ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage (UGIH). METHODS: This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011. RESULTS: A total of 1249 patients were registered for severe UGIH in the data basis, 461 (36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen (75%) subjects required posterior nasal packing and 2 (10%) embolization in addition to correction of coagulopathy. Five (25%) patients died in the hospital, 12 (60%) received orthotopic liver transplantation (OLT), and 3 (15%) were discharged without OLT. The mortality rate was 63% in patients without OLT. CONCLUSION: Severe epistaxis in patients with ESLD is (1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH; and (2) associated with a high mortality rate in patients not receiving OLT.

The cost of screening esophageal varices: traditional endoscopy versus computed tomography.

OBJECTIVE: Under current guidelines, patients diagnosed with cirrhosis are to undergo initial and continued screening endoscopy for esophageal varices throughout the course of disease. Recent literature suggests that computed tomography (CT) of the abdomen is adequately sensitive for detecting grade 3 varices, those in need of immediate intervention. This study presents a cost comparison of traditional endoscopy versus CT of the abdomen. METHODS: Using TreeAge Pro software, a budget impact cost model was created for a hypothetical managed care organization covering 1 million lives over a 10-year period. Incidence figures for cirrhosis and the progression of esophageal varices were applied to the patient population. National Medicare reimbursement costs were used to compare screening with traditional endoscopy versus CT. Costs utilizing screening with combined endoscopy and CT were also examined. RESULTS: The results of comparing screening paradigms under a budget impact cost model results in an outcome measure termed "per-member, per-month" (PMPM) cost of implementing a new strategy. Computed tomography was the least expensive modality with an average 10-year cost per screened patient of $1097.30 and PMPM of $0.03. Endoscopy was the most expensive modality with an average 10-year cost per screened patient of $1464.89 and PMPM of $0.04. CONCLUSION: Computed tomography has been shown to be sensitive in detecting esophageal varices and now less costly to implement in screening. The cost of esophageal rupture in endoscopy and the less costly risk of contrast reaction as well as radiation exposure in CT of the abdomen should be considered when developing a screening paradigm.

Ischemic colitis as a cause of severe hematochezia: risk factors and outcomes compared with other colon diagnoses.

BACKGROUND: Risk factors and outcomes of severe hematochezia from ischemic colitis compared with other colonic diagnoses have not been well studied. OBJECTIVE: Our purposes were (1) to compare demographics and outcomes of patients hospitalized with severe hematochezia from ischemic colitis compared with other colonic diagnoses, (2) to compare inpatient and outpatient start of bleeding from ischemic colitis, and (3) to describe potential risk factors. DESIGN: Prospective cohort study. SETTING: Tertiary referral academic centers. PATIENTS: Patients referred for gastroenterology consultation for severe hematochezia. INTERVENTIONS: Colonoscopic therapy was provided as indicated. MAIN OUTCOME MEASUREMENTS: Rebleeding, surgery, and length of hospital stay after colonoscopy. RESULTS: Of 550 patients in the past 12 years with severe hematochezia from colonic sources, the cause in 65 patients (11.8%) was ischemia. Ischemic colitis was found more often in females, in patients taking anticoagulant agents, in patients with severe lung disease, those with higher creatinine levels, those with higher glucose levels, and those with more fresh frozen plasma transfusions. Five patients with focal lesions had colonoscopic hemostasis. Major 30-day outcomes of ischemic colitis patients were significantly worse than patients with other colonic diagnoses. Patients with inpatient (vs outpatient) ischemic colitis had significantly more and more severe comorbidities at baseline and significantly higher rates of rebleeding, surgery, and more days spent in hospital and in the intensive care unit. LIMITATIONS: Two-center study. CONCLUSIONS: Major 30-day outcomes in ischemic colitis patients were significantly worse than in patients with other colonic diagnoses. Comparing outpatient and inpatient start of ischemic colitis, inpatients had significantly worse outcomes.

Randomized prospective study of endoscopic rubber band ligation compared with bipolar coagulation for chronically bleeding internal hemorrhoids.

OBJECTIVES: Our purpose was to compare the efficacy, complications, success rate, recurrence rate at 1 year, and crossovers of rubber band ligation (RBL) with those of bipolar electrocoagulation (BPEC) treatment for chronically bleeding internal hemorrhoids. METHODS: A total of 45 patients of mean age 51.5 years, who had rectal bleeding from grade II or III hemorrhoids and in whom intensive medical therapy failed, were randomized in a prospective study comparing RBL with BPEC. Treatment failure was predefined as continued bleeding, occurrence of a major complication, or failure to reduce the size of all internal hemorrhoidal segments to grade I in < or =3 treatments. Patients were followed up for 1 year. RESULTS: With similar patients, rectal bleeding and other symptoms were controlled with significantly fewer treatments of RBL than of BPEC (2.3+/-0.2 vs. 3.8+/-0.4, P<0.05), and RBL had a significantly higher success rate (92% vs. 62%, P<0.05). RBL had more cases of severe pain during treatment (8% vs. 0%, P<0.05), but significantly fewer failures and crossovers (8% vs. 38%). Symptomatic recurrence at 1 year was 10% RBL and 15% BPEC. CONCLUSIONS: For patients with chronically bleeding grade II or III internal hemorrhoids that are unresponsive to medical therapy, safety and complication rates of banding and BPEC were similar. The success rate was significantly higher with RBL than with BPEC. Symptom recurrence rates at 1 year were similar.

Esophageal varices in cirrhotic patients: evaluation with liver CT.

OBJECTIVE: The objective of this study was to evaluate the performance of routine helical liver CT in the detection and grading of esophageal varices in cirrhotic patients. MATERIALS AND METHODS: A total of 67 consecutive cirrhotic patients who underwent both upper endoscopy and helical liver CT within a 4-week interval were evaluated. The CT protocol included unenhanced, arterial, and portal phases with a collimation of 7-7.5 mm. Two blinded abdominal imagers (6 and 7 years' experience) retrospectively interpreted all CT images to detect the presence of esophageal varices on a 5-point confidence scale and measure the largest varix identified. Receiver operating characteristic (ROC) curve analysis was performed, and the correlation between CT measurements and endoscopic grading, the reference standard, was assessed. RESULTS: The variceal detection rates for the observers was 92% (11/12) and 92% (11/12) for large (i.e., clinically significant) varices, 53% (16/30) and 60% (18/30) for small varices, and 64% (27/42) and 69% (29/42) for all varices. The area under the ROC curve for the detection of esophageal varices of any size was 0.77 (observer 1) and 0.80 (observer 2). CT variceal grading showed a strong correlation with endoscopic grading for both observers (p < or = 0.001). Using a variceal diameter threshold of 3 mm on CT, sensitivity, specificity, and accuracy for distinguishing large esophageal varices from small or no varices were 92% (11/12), 84% (46/55), and 85% (57/67), respectively, for both observers. CONCLUSION: Liver CT is useful for the detection and grading of esophageal varices. A diameter of 3 mm may be an appropriate screening threshold for large clinically significant varices.

Sensitivity and inter-observer variability for capsule endoscopy image analysis in a cohort of novice readers.

AIM: To determine the performance of novice readers (4th year medical students) for detecting capsule endoscopy findings. METHODS: Ten capsule endoscopy cases of small bowel lesions were administered to the readers. Gold standard findings were pre-defined by gastroenterologists. Ten gold standard "targets" were identified among the 10 cases. Readers were given a 30-min overview of Rapid Reader software and instructed to mark any potential areas of abnormalities. A software program was developed using SAS to analyze the thumbnailed findings. RESULTS: The overall sensitivity for detecting the gold standard findings was 80%. As a group, at least 5 out of 10 readers detected each gold standard finding per recording. All the gold standard targets were identified when the readers' results were combined. Incidental finding/false positive rate ranged between 8.2-59.8 per reader. CONCLUSION: A panel of medical students with minimal endoscopic experience can achieve high sensitivity in detecting lesions on capsule endoscopy. A group of novice readers can pre-screen recordings to thumbnail potential areas of small bowel lesions for further review. These thumbnails must be reviewed to determine the clinical relevance. Further studies are ongoing to assess other cohorts.

Randomized study comparing banding and propranolol to prevent initial variceal hemorrhage in cirrhotics with high-risk esophageal varices.

BACKGROUND & AIMS: Standard care for prevention of first esophageal variceal hemorrhage is beta-blockade, but this may be ineffective or unsafe. Our purpose was to compare endoscopic banding with propranolol for prevention of first variceal hemorrhage. METHODS: In a multicenter, prospective trial, 62 patients with cirrhosis with high-risk esophageal varices were randomized to propranolol (titrated to reducing resting pulse by > or =25%) or banding (performed monthly until varices were eradicated) and were followed up on the same schedule for a mean duration of 15 months. The primary end point was treatment failure, defined as the development of endoscopically documented variceal hemorrhage or a severe medical complication requiring discontinuation of therapy. Direct costs were estimated from Medicare reimbursements and fixed or variable charges for services up to treatment failure. RESULTS: Background variables of the treatment groups were similar. The trial was stopped early after an interim analysis showed that the failure rate of propranolol was significantly higher than that of banding (6/31 vs. 0/31; difference, 19.4%; P = .0098; 95% confidence interval for true difference, 6.4%-37.2%). Significantly more propranolol than banding patients had esophageal variceal hemorrhage (4/31 vs. 0/31; difference, 12.9%; P = .0443; 95% confidence interval for true difference, 0.8%-29%), and the cumulative mortality rate was significantly higher in the propranolol than in the banding group (4/31 vs. 0/31; difference, 12.9%; P = .0443; 95% confidence interval for true difference, 0.8%-29%). Direct costs of care were not significantly different. CONCLUSIONS: For patients with cirrhosis with high-risk esophageal varices and no history of variceal hemorrhage, propranolol-treated patients had significantly higher failure rates of failure, first esophageal varix hemorrhage, and cumulative mortality than banding patients. Direct costs of medical care were not significantly different.

Major stigmata of recent hemorrhage on rectal ulcers in patients with severe hematochezia: Endoscopic diagnosis, treatment, and outcomes.

BACKGROUND: Endoscopic diagnosis and treatment of hematochezia caused by rectal ulcers is poorly described. METHODS: Consecutive patients hospitalized with severe hematochezia underwent urgent colonoscopy after purge. Those with rectal ulcers were divided into 2 groups based on the absence or presence of major stigmata of recent hemorrhage: active bleeding, visible vessel, or adherent clot. Major stigmata were treated with epinephrine injection and coagulation with a bipolar probe. The primary outcome endpoint was recurrent bleeding within 4 weeks of diagnosis. RESULTS: Rectal ulcers were identified in 23 of 285 (8%) patients. Twelve of 23 patients had major stigmata; these patients had an arithmetically greater decrease in hematocrit and required more blood transfusions than patients without major stigmata. Initial hemostasis was achieved in all, but bleeding recurred in 5 with stigmata. Four patients died of comorbid conditions. There was no recurrent bleeding or death in those without stigmata. CONCLUSIONS: Patients with rectal ulcers harboring major stigmata are at high risk for severe bleeding, recurrent bleeding, and death. For ulcers with major stigmata, endoscopic hemostasis is feasible but rates of recurrent bleeding are high.

Randomized trial of medical or endoscopic therapy to prevent recurrent ulcer hemorrhage in patients with adherent clots.

BACKGROUND & AIMS: Treatment of high-risk patients with nonbleeding adherent clots on ulcers is controversial. In a previous randomized trial, there was no benefit to endoscopic therapies compared with medical therapy for prevention of ulcer rebleeding. Our purpose was to test the hypothesis that patients treated with combination endoscopic therapy would have significantly lower rebleeding rates than those treated with medical therapy. METHODS: In this randomized, controlled trial, 32 high-risk patients with severe ulcer hemorrhage and nonbleeding adherent clots resistant to target irrigation were randomized to medical therapy or to combination endoscopic therapy (with epinephrine injection, shaving down the clot with cold guillotining, and bipolar coagulation on the underlying stigmata). Physicians blinded to the endoscopic therapy managed all patients. RESULTS: Patients were similar at study entry, except for older age in the medical group and lower platelet count in the endoscopic group. By hospital discharge, significantly more medically treated patients (6/17; 35.3%) than endoscopically treated patients (0/15; 0%) rebled (P = 0.011). There were no complications of endoscopic treatment. CONCLUSIONS: Combination endoscopic therapy of nonbleeding adherent clots significantly reduced early ulcer rebleeding rates in high-risk patients compared with medical therapy alone. This endoscopic treatment was safe.
