ABSTRACT

BACKGROUND AND AIMS: Feed intolerance (FI) is common in cirrhosis patients in intensive care units (ICU). Prokinetics are the first line treatment for FI but their efficacy and safety in critically ill patient with cirrhosis is unknown. We evaluated the role of prokinetics in reversal of FI and clinical outcomes. METHODS: Consecutive patients admitted in ICU developing new-onset FI, were randomized to receive either intravenous metoclopramide (Gr.A, n = 28), erythromycin (Gr.B, n = 27) or placebo (Gr.C, n = 28). FI was defined with the presence of 3 of 5 variables- absence of bowel sounds, gastric residual volume ≥ 500 ml, vomiting, diarrhoea and bowel distension. Primary end-point was complete resolution of FI (≥ 3 variables resolved) within 24-h and secondary end-points included resolution within 72-h and survival at 7-days. RESULTS: Of the 1030 ICU patients, 201 (19.5%) developed FI and 83 patients were randomized. Baseline parameters between the groups were comparable. Complete resolution at 24-h was higher in Gr.A (7.14%) and B (22.2%) than C (0%, p = 0.017). Overall, 58 (69.9%) patients achieved resolution within 72 h, more with metoclopramide (n = 24, 85.7%) and erythromycin (n = 25, 92.6%) than with placebo (n = 9, 32.1%, p < 0.001). The 7-day survival was better in patients who achieved resolution within 72-h (65.5 vs. 36%, p = 0.011) than non-responders. High lactate (OR-3.32, CI-1.45-7.70, p = 0.005), shock at baseline (OR-6.34, CI-1.67-24.1, p = 0.007) and resolution of FI within 72 h (OR-0.11, CI, 0.03-0.51, p = 0.04) predicted 7-day mortality. CONCLUSIONS: FI is common in critically-ill cirrhosis patients and non-resolution carries high mortality. Early recognition and treatment with prokinetics is recommended to improve short-term survival.


Gastrointestinal dysmotility is common in cirrhosis and higher incidence in critically ill patients. Promotility drugs are the first line of medication especially in ICU patients. In our study, we found that feed intolerance is present in nearly one in five critically ill cirrhosis and is associated with higher mortality. Patients who achieve resolution had an improved short-term survival. Prokinetic medications are safe in critically ill cirrhosis and help in early resolution of feed intolerance. Feed intolerance in critically ill cirrhosis should be recognized as an organ dysfunction and approaches for prevention and early diagnosis of feed intolerance could help in improving the outcomes in critical illness.

ABSTRACT

Sister Mary Joseph nodules represent metastatic cancer of the umbilicus. More than half of these cases are attributable to gastrointestinal malignancies including gastric, colonic, and pancreatic cancer. In addition, gynecologic (ovarian, uterine cancer), unknown primary tumors, and, rarely, bladder or respiratory malignancies may cause umbilical metastasis. We report the case of a Sister Mary Joseph nodule originating from a hilar cholangiocarcinoma. Umbilical nodules should prompt clinical evaluation, as these tumors are usually associated with poor prognosis.

ABSTRACT

BACKGROUND: Based on their chemical extraction, dietary fibers are classified into crude fibers and total dietary fibers (TDF). TDF gives the best estimate of fiber content in the diet. Whereas data on intake of crude fibers are available, there is a lack of data on intake of TDF in patients with irritable bowel syndrome (IBS). AIM: We assessed the TDF and its source in the diet of patients with IBS and healthy controls (HC). METHODS: Based on their predominant symptoms, 81 patients with IBS (according to Rome II criteria) were categorized into constipation-predominant (IBS-C, n=48), diarrhea-predominant (IBS-D, n=16) and mixed type (IBS-M, n=17). Information was collected on fiber supplementation and preference for high-fiber food. A pretested, open-ended, semi-quantitative food frequency questionnaire was used to collect dietary information on food groups and TDF. Age- and sex-matched healthy individuals (n=89) were recruited as HC. The mean (SD) age of patients and HC was 36.5 (11.4) years (59 men), and 36 (12) years (62 men), respectively. RESULTS: Thirty-nine patients (48%) were taking medicinal fiber supplements, of which 28 patients were taking supplements daily (2.10 [0.84] teaspoon full). The mean daily TDF intake was 51.7 (23.1) g vs. 52.3 (21.6) g for patients and HC, respectively (p=0.8). The intake of TDF was similar in patients having less (n=41) or more (n=40) preference for fiber-rich foods (55 [23] g vs. 47 [22] g, p=0.16). The daily mean cereal intake in patients was significantly lower than that in HC (322 g vs. 404 g, p=0.001). However, consumption of fruits (150 g vs. 80 g, p=0.001) and vegetables (348 g vs. 219 g, p=0.006) was higher in patients in comparison with HC. There was a positive correlation between TDF with cereals (p=0.001), pulses (p=0.001), vegetables and fruits (p=0.033) in patients with IBS but only with cereals (p=0.001) in HC. CONCLUSION: The intake of TDF in patients with IBS and HC is much higher than the dietary recommendation for healthy Indians. Patients with IBS consumed more fruits and vegetables rather than cereals as compared with HC.

ABSTRACT

OBJECTIVES: Familial clustering of HBV provides epidemiological evidence for the different modes of spread of the virus. Though the majority of the studies have addressed the issue of perinatal transmission in India, only a few reports have dealt with other modes of transmission. METHODS: The study was prospectively designed and data were collected from a total of 265 household contacts of 91 index patients with HBV-related chronic liver disease between January 2006 and July 2007. The prevalences of HBsAg and various antibodies; anti-HBs, anti-HBc and anti-HBe, were estimated in all household contacts using ELISA and VIDAS. RESULTS: Among the various household contacts, the highest prevalence of HBsAg was seen in the pediatric age group (kids 1-15 years: 37.0%) and especially in siblings (48.3%), with statistical significance (p < 0.001). Hepatitis B virus (HBV) serological markers were found more commonly in contacts of female (68.8%) index patients as compared to males (p > 0.05). The development of anti-HBV antibodies showed an increasing trend with age (p < 0.001), with the highest prevalence in parents. CONCLUSION: Horizontal transmission plays an important role in contributing to the high prevalence of HBsAg especially in young children. Hence, this age group needs to be targeted for primary prevention and effective vaccine.

ABSTRACT

OBJECTIVES: To investigate the effect of viral hepatitis on serum levels of apo- and lipoproteins in different forms of liver diseases. MATERIALS AND METHODS: One hundred and thirty adult patients and 100 healthy age- and gender-matched control individuals participated in this study. Patients were grouped according to four types of liver disease: acute viral hepatitis, chronic active hepatitis (CAH), cirrhosis of the liver and fulminant hepatic failure. RESULTS: Hepatitis B virus, C virus and E virus (HEV) infections were recorded in different combinations in these patients, but viral infections of hepatitis A and D were not seen in any of the patient groups. The results of lipo- and apoprotein analysis showed different patterns. The low-density lipoprotein value was high in the CAH group. In the other three groups, low-density lipoprotein level was comparable to the control value. The high-density lipoprotein level (p = 0.02) was significantly low in all groups except in the cirrhosis group. Apo-A was significantly reduced in the acute viral hepatitis and fulminant hepatic failure groups, whereas Apo-B level was low in the CAH and cirrhosis groups. The lipoprotein (a) level in these groups was low, compared to control. CONCLUSION: No apparent relationship was observed between etiological viruses and ensuing changes in lipid/lipoprotein profile..

ABSTRACT

BACKGROUND/AIMS: The present study was designed to investigate the effect of hepatitis C virus (HCV) core protein expression on the blood level of lipids, lipoproteins and apolipoprotein in various forms of liver diseases. At the same time, effect of HCV core protein was also studied on the level of antioxidants in these patient groups. The aim behind this study was to explore the possibility of HCV core induced lipid changes and ensuing oxidative liver damage in these liver diseases. METHODOLOGY: We studied a total number of 130 patients including 50 patients with acute viral hepatitis (AVH), 30 with chronic hepatitis (CH), 30 with hepatic cirrhosis and 20 patients with fulminant hepatic failure (FHF). Sera from all these patients were analyzed for hepatitis viral markers and HCV core protein using EIA assays. Sera/plasma from them were simultaneously analyzed for total cholesterol, triglyceride, low density lipoprotein (LDL), high density lipoprotein (HDL), apolipoprotein A-1 and B, and also for antioxidants. RESULTS: Analysis of data demonstrated the presence of viral hepatitis B, C and E infections in these cases. Hepatitis A and D infections were absent in all the patients. When data on lipid and lipoprotein were analyzed in relation to HCV core expression, we could not observe a significant change in the serum level of total cholesterol, triglyceride, LDL, HDL, apolipoprotein A-1 and apoprotein B in core positive patients as compared to core negative cases. However, lipoprotein (a) [Lp(a)] level was significantly reduced in core positive patients as compared to core negative cases. Furthermore, analysis of Superoxide dismutase (SOD), Total antioxidant (TAO) and Uric Acid in these patients demonstrated only a minor change in SOD and TAO levels in relation to HCV core, though at the same time, Uric Acid was found raised in all the groups. CONCLUSIONS: These observations clearly indicate that core expression does not bring a significant change in serum level of lipids, lipoprotein and apoproteins. Similarly, HCV core expression also does not show a major change in SOD and TAO levels suggesting an insignificant impact of core on oxidative stress during liver diseases.

ABSTRACT

The present review gives an updated overview of transfusion transmitted virus (TTV), a novel agent, in relation to its molecular characteristics, epidemiological features, modes of transmission, tissue tropism, pathogenesis, role in various diseases and its eradication from the body. TTV, a DNA virus, is a single stranded, non-enveloped, 3.8 kb long DNA virus with a small and covalently closed circular genome comprising 3852 bases. It was tentatively designated Circinoviridae virus. TTV genome sequence is heterogeneous and reveals the existence of six different genotypes and several subtypes. TTV has been reported to transmit not only via parenteral routes, but also via alternate routes. This virus has been detected in different non-human primates as well. At present, TTV is detected by polymerase chain reaction (PCR) with no other available diagnostic assays. It shows its presence globally and was detected in high percent populations of healthy persons as well as in various disease groups. Initially it was supposed to have strong association with liver disease; however, there is little evidence to show its liver tropism and contribution in causing liver diseases. It shows high prevalence in hemodialysis patients, pointing towards its significance in renal diseases. In addition, TTV is associated with several infectious and non-infectious diseases. Though, its exact pathogenesis is not yet clear, TTV virus possibly resides and multiplies in bone marrow cells and peripheral blood mononuclear cells (PBMCs). Recently, attempts have been made to eradicate this virus with interferon treatment. More information is still needed to extricate various mysteries related to TTV.

ABSTRACT

AIM: To describe the prevalence of transfusion-transmitted virus (TTV) infection in association with hepatitis A-E viral infections in different forms of liver diseases in North India. METHODS: Sera from a total number of 137 patients, including 37 patients with acute viral hepatitis (AVH), 37 patients with chronic viral hepatitis (CVH), 31 patients with cirrhosis of liver and 32 patients with fulminant hepatic failure (FHF), were analyzed both for TTV-DNA and hepatitis A-E viral markers. Presence of hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis E virus (HEV) infections was detected in different proportions in different groups. Moreover, TTV-DNA was simultaneously tested in 100 healthy blood donors also. RESULTS: None of the patients had hepatitis A virus (HAV) and hepatitis D virus (HDV) infections. Overall prevalence of TTV-DNA was detected in 27.1% cases with AVH, 18.9% cases with CVH, 48.4% cases with cirrhosis and 9.4% cases with FHF. TTV-DNA simultaneously tested in 100 healthy blood donors showed 27% positivity. On establishing a relation between TTV infection with other hepatitis viral infections, TTV demonstrated co-infection with HBV, HCV and HEV in these disease groups. Correlation of TTV with ALT level in sera did not demonstrate high ALT level in TTV-infected patients, suggesting that TTV does not cause severe liver damage. CONCLUSION: TTV infection is prevalent both in patients and healthy individuals in India. However, it does not have any significant correlation with other hepatitis viral infections, nor does it produce an evidence of severe liver damage in patients with liver diseases.

ABSTRACT

BACKGROUND: Relapse of pain during refeeding in acute pancreatitis may have a relation to the route of refeeding. AIM: To compare the efficacy of oral refeeding with jejunal tube refeeding in patients with acute pancreatitis, and determine the frequency of refeeding pain and factors associated with it. METHODS: Consecutive patients with acute pancreatitis, severe enough to stop oral feeding for 48 hours, were randomized to receive either oral or jejunal tube refeeding. The feeds were similar in calorie, lipid and protein content (400 Kcal on day 1, 1000 Kcal on day 2, 1400 Kcal on day 3, 1500 Kcal on day 4, and 1700 Kcal on day 5). Clinical and biological factors (serum amylase, lipase, C-reactive protein) and Balthazar CT severity index were recorded. Frequency of pain relapse and factors associated with it were analyzed. RESULTS: 28 patients with acute pancreatitis (biliary 14, alcohol 9, idiopathic 3, post-ERCP 2) were included. Fifteen patients received oral and 13 received enteral tube refeeding. Four patients in the oral group and none in the enteral tube group had relapse of pain (p=0.06). The factors associated with refeeding pain were longer duration of initial pain (p<0.02) and higher CT severity index (p<0.02). Pain relapse increased the total hospital stay (p<0.004) and hospital stay after the first attempt at feeding (p<0.001). CONCLUSIONS: Jejunal tube refeeding may reduce the frequency of pain relapse as compared to oral refeeding although the difference was not significant in this study. Longer duration of pain and higher CT severity index score were associated with occurrence of refeeding pain.

ABSTRACT

Nutritional factors play a major role both in the pathogenesis as well as management of hepatic encephalopathy (HE). Physicians treating patients with chronic liver disease often restrict the intake of dietary protein to prevent a rise in blood ammonia levels. The role of protein restriction in patients with chronic hepatic encephalopathy (CHE) has been questioned recently as the efficacy of protein withdrawal in patients with CHE has never been subjected to a controlled trial. Evidence suggests that protein intake plays only a limited role in precipitating encephalopathy. In fact, measures taken to suppress endogenous protein breakdown are more effective than dietary restrictions in reducing the load of amino acids on the decompensated liver. A protein intake of less than 40 g per day, as has been indicated, contributes to a negative nitrogen balance, which along with increased endogenous protein breakdown, worsens encephalopathy. A positive nitrogen balance may have positive effects on encephalopathy. Rather, depressed plasma branched-chain amino acid (BCAA) levels, implicated in the pathogenesis of HE, also supervene in cirrhosis only when malnutrition is present as well. Therefore, the emphasis in the nutritional management of patients with HE should not be on the reduction of protein intake. Instead, the goal should be to promote synthesis by making available ample amounts of amino acids, while instituting other measures to reverse the ongoing catabolism. Different protein sources have varying effects on HE and efforts should be made to identify the most tolerated protein source to prevent malnutrition and maintain these patients on a long-term basis.

ABSTRACT

BACKGROUND AND AIMS: Discovery of an isoform of Cyclo-oxygenase (COX) 1, the inducible COX-2, has made it possible to avoid some side effects of non-specific COX inhibitors. The COX-2 gene is over-expressed in reflux oesophagitis, Barrett's oesophagus, gastric and colon cancer, familial adenomatous polyposis, pancreatic cancer, hepatocellular carcinoma, hepatotoxicity, cirrhosis, and inflammatory bowel disease, and specific COX-2 inhibitors have been tried experimentally and clinically and found effective. METHODS: A Medline search was performed of English-language experimental studies and controlled clinical trials from January 1980 to January 2002, and relevant citations were noted. RESULTS: Review of available literature shows that sulindac and COX-2 inhibitors are effective in preventing as well as regressing familial adenomatous polyposis. However, they have not been shown to prevent cancer in these patients. Studies evaluating NSAIDs and COX-2 inhibitors in carcinogen-induced and genetically manipulated animal models of various cancers have been promising especially in conditions such as Barrett's oesophagus, oesophageal and hepatocellular carcinoma and pancreatic cancer. COX-2 inhibitors may be of value in the treatment of reflux oesophagitis, pancreatitis and hepatitis, although carefully planned randomized controlled clinical trials demonstrating their efficacy need to be conducted. At present NSAIDs and COX-2 inhibitors cannot be recommended for average-risk individuals or for those with sporadic colorectal neoplasia (or other forms of cancers) as chemo-preventive agents. CONCLUSION: COX-2 inhibitors may open up a new therapeutic era in which these drugs can be used for chemo-prophylaxis. However, COX-2 selective inhibitors retain renal adverse effects of the non-selective inhibitors and the concern regarding the pro-thrombotic potential of COX-2 inhibitors will limit their value as chemo-preventive agents.

ABSTRACT

OBJECTIVES: Water borne or enterically transmitted non-A-non-B hepatitis is a major public health problem in India. Many of these cases carry fatal outcome. The hepatitis E virus (HEV) has been considered to be the most important causative agent of this entity. The severity and fatality rates of HEV infection are reported to be rather more in pregnant women. However, there is meager information from India, on mother to child transmission of this agent. METHODS: During 1997-98, we studied 60 pregnant women suspected to have acute viral hepatitis to understand the frequency of various viral etiologies, disease course and outcome of the pregnancy. Six cord blood samples were tested for IgG, and IgM antibodies against hepatropic viral agents and also for hepatitis E virus RNA by RT-nested PCR using ORF-1 as target. RESULTS: Of the 60 pregnant patients hospitalised at All India Institute of Medical Sciences, New Delhi for acute hepatitis, 22 (37%) were positive for IgM anti-HEV antibodies and 10% were infected with hepatitis B virus. Co-infection of HEV with Hepatitis B and C was seen in 1 and 2 patents, respectively. Most (72%) of the HEV infected patients were in third trimester of pregnancy (P<0.05). Of the 6 cord blood samples tested 3 (50%) were positive for HEV RNA. Though, all mothers were RNA positive, half of the babies did not get infected in utero with HEV. Fourteen of the 22 (63.6%) HEV infected mothers developed fulminant hepatic failure and all died. CONCLUSION: The mortality rate in HEV [corrected] infected mothers was 100%. Mother to child transmission of hepatitis E virus infection was established in 50%.

ABSTRACT

In order to understand the impact of viral hepatitis on anti-oxidant defence system of the body, blood levels of superoxide dismutase (SOD), an enzymatic anti-oxidant, and total anti-oxidant (TAO) were evaluated and co-related to etiological viral hepatitis in various forms of liver diseases. A total number of 110 patients including 50 patients with acute viral hepatitis (AVH), 30 patients with chronic active hepatitis (CAH) and 30 patients with cirrhosis of liver were analysed for different hepatitis viral markers and the anti-oxidant levels in their blood. For comparison, blood from 100 healthy persons were also simultaneously tested for anti-oxidant levels. Analysis of results indicated that none of the patients belonging to these three liver diseases had hepatitis A viral (HAV) and hepatitis D viral (HDV) infections. AVH group had mainly hepatitis B viral (HBV), hepatitis C viral (HCV) and hepatitis E viral (HEV) infections, CAH group had B and C infections and cirrhosis group had B, C and E infections. A sizeable number of patients in each group had no markers and were labelled as non-BCE group. On co-relating anti-oxidant levels to viral etiology in these patients, it was observed that in comparison to healthy control group, SOD level was significantly reduced in all the patients irrespective of the viral etiology (P<0.05-0.001). The impact of different viruses on reduction in SOD level was recorded to be the same with no significant difference in SOD level between any two viral infections. On the contrary, TAO level in the majority of patients was found to be comparable with that observed in healthy persons. An appreciable change in SOD level but little impact on TAO level during viral hepatitis may be explained by the possible adaptive rise of some other anti-oxidant level in the blood of these patients.

ABSTRACT

BACKGROUND AND AIMS: The P300 event-related potentials (P3ERP) have been recently advocated for detection of cognitive disturbances in early encephalopathy. However, no systematic follow-up study has been conducted to understand the clinical significance of subclinical hepatic encephalopathy (SHE) detected by this or other methods. The present study was therefore undertaken to examine the diagnostic usefulness of auditory P3ERP in the detection of SHE, to compare it with that of the number connection test (NCT), and to investigate the clinical outcome of patients with SHE in terms of progression to overt encephalopathy. METHODS: P300 event-related potential latencies were measured and the NCT time was recorded in 81 non-encephalopathic cirrhotic patients (Aged 43.8 +/- 11 years, 23 alcoholic and 58 non-alcoholics) attending the outpatient department at our tertiary care hospital (All India Institute of Medical Sciences Hospital). Cut-off values for abnormality in the tests were developed from age-, sex- and education-matched controls. Patients were followed up at regular intervals for the development of overt encephalopathy, and the identifiable precipitating factors were noted. The P3ERP latencies (363 +/- 34 msec vs 349 +/- 23 msec), as well as NCT time (54.6 +/- 30.6 s vs 39.5 +/- 15.8 s) were significantly prolonged (P< 0.01) in patients with liver cirrhosis when compared with the non-cirrhotic controls. RESULTS: The P3ERP defects were seen in 24.6% of cirrhotic patients, while NCT time was prolonged in 19.7% of the patients. Nearly 43% of the patients with SHE progressed to overt encephalopathy within a mean duration of 5 months, while only 3.9% of the non-SHE patients did so. Of the patients who developed overt encephalopathy, 64.2% had P3ERP latency prolongations while 35.7% had abnormal NCT. CONCLUSIONS: The results of the present study suggest that P3ERP and NCT are valid tools for the screening of SHE in cirrhotic patients as there is a greater likelihood of overt encephalopathy development in patients with an abnormality detected by these tests than in patients with no such abnormality.

ABSTRACT

BACKGROUND AND OBJECTIVES: information on the incidence and prevalence of hepatitis E virus (HEV) infection in Indian pregnant women is scanty. Only a few studies have been done so far to document the vertical route of transmission of this virus. We therefore studied the prevalence of HEV infection in pregnant women with hepatitits and the outcome of their pregnancy. METHODS: fifty pregnant women with clinical hepatitits were included in the study. After informed consent, their blood samples were tested for potential causes of hepatitis including hepatitis A, B, hepatitis C, and hepatitis E infections. RESULTS: of the 50 cases, 20 (40%) patients were found to be positive for IgM anti -HEV (group A) and 30 (60%) were negative for IgM anti-HEV antibodies (group B). Overall 19 patients were in their second trimester while 30 were in third trimester. Of these 52.6 per cen (10/19) of those in second trimester and 50 per cent (15/30) in third trimester had fulminant hepatic failure (FHF). Only one patient presented in the first trimester who had acute viral hepatitis (AVH) and recovered completely. Of the HEV infected women, 70 per cent were in their third trimester and remaining 30 per cent in second trimester of pregnancy. A similar percentage of patients i.e., 14 of 20 (70%) manifested with FHF while 6 (30%) had acute hepatitis leading to recovery. The percentage of women with FHF and acute hepatitis was 36.6 and 63 per cent, respectively, in group B. Upon follow up all the 13 of the 14 HEV infected patients with FHF expired and only one delivered a male baby during the illness. The fatality rate in HEV infected patients was not different between the second and third trimesters (66.6% vs. 71.43%), respectively). INTERPRETATION AND CONCLUSIONS: this study suggests that HEV causes high mortality in pregnant women as compared to non-HEV infected pregnant women. This pilot study indicates that steps should be taken to prevent HEV infection during pregnancy.

ABSTRACT

OBJECTIVE: The present case-control study was undertaken with the objective to study the nutritional risk factors associated with esophageal cancer. METHODOLOGY: One hundred and fifty diagnosed esophageal cancer patients and an equal number of healthy individuals constituted the patient and control groups, respectively. Dietary consumption pattern during the preceding 20 years prior to the diagnosis of esophageal cancer was assessed utilising the standard food frequency questionnaire method. Information on alcohol consumption, smoking habits, chewing of betel leaf with tobacco was also collected. RESULTS: Multivariate analysis revealed that the risk of esophageal cancer was 7.81 times (p < 0.01) higher with daily consumption of alcohol. The risk increased to 3.16 times (p < 0.01) with the daily habit of chewing of betel leaf with tobacco. Nearly a two fold risk was observed when the consumption of "other vegetables" was less than four times per week. A 1.95 times (p < 0.01) increase in risk was observed with the daily habit of bidi smoking. CONCLUSION: Cancers in general are multifactorial in origin, and several environmental interactions are possible. It is not easy to quantify the contribution of diet to cancer risk. However, the results of the present study suggested that nutritional factors do play a role.

ABSTRACT

BACKGROUND: Endoscopic variceal sclerotherapy and band ligation both have certain limitations such as, respectively, esophageal complications and early recurrence of varices. METHODS: From February 1994 to March 1996, all consecutive patients with portal hypertension due to either cirrhosis or noncirrhotic portal fibrosis and a history of variceal bleeding were included in a prospective study and randomly assigned to receive either endoscopic variceal sclerotherapy alone or endoscopic variceal band ligation plus low-dose endoscopic variceal sclerotherapy. RESULTS: Of 69 patients, 34 were randomly assigned to receive endoscopic variceal sclerotherapy alone; 35 received endoscopic variceal band ligation plus endoscopic variceal sclerotherapy. Complete variceal eradication rates (85% vs. 80%) and the number of endoscopic sessions required for eradication (6.61 +/- 2.94 vs. 7.85 +/- 3.31) were similar in the endoscopic variceal sclerotherapy and endoscopic variceal band ligation plus endoscopic variceal sclerotherapy groups, respectively. The mean volume of sclerosant required in the combined group (54.94 +/- 33.74 mL) was significantly less than that in the endoscopic variceal sclerotherapy group (81.91 +/- 34.80 mL). The complication and recurrent bleeding rates were significantly higher in the endoscopic variceal sclerotherapy group than those in the combined group (20% and 16% vs. 3% and 3%, respectively). CONCLUSIONS: Both endoscopic variceal sclerotherapy and endoscopic variceal band ligation plus endoscopic variceal sclerotherapy were comparable in eradicating varices but the combined technique was associated with significantly lower complication and recurrent bleeding rates.
