Balloon tamponade in the management of bleeding oesophageal varices.

Sixty-three patients with acute variceal haemorrhage were treated with the Sengstaken-Blakemore tube (SBT). Bleeding was initially controlled with the gastric balloon in 37 patients (60%) and with both gastric and oesophageal balloons in another 17 (27%), giving overall primary success in 54 patients (87%). Sixteen (26%) patients re-bled within 24 hours of deflation of the tube. Repeat balloon tamponade helped in controlling bleeding in 9 of these. Thus, a total of 47 (75%) patients stopped bleeding with SBT. There was no mortality. The only major complication was pulmonary infection (15%), which improved with antibiotics. Use of the SBT was found to be simple, quick, low cost and attended with few complications. Its use is recommended in patients with acute variceal bleeding, especially in developing countries with limited resources.

Pulmonary hemodynamic changes after intravariceal sclerotherapy with absolute alcohol.

To investigate whether alcohol used as variceal sclerosant has any effect on pulmonary hemodynamics, 14 patients with portal hypertension received intravariceal injections of absolute alcohol. Six additional patients were injected with equivalent volumes of saline and they served as controls. After intravariceal injection of absolute alcohol (8 ml in 12 patients and 12 ml in 2 patients), mean +/- SD pulmonary artery pressure was seen to increase significantly (p less than 0.01) at 1 and 5 min and return to basal level by 15 min. Similar changes in pulmonary arterial pressure were seen after intravariceal injection of saline; the difference in the rise in pulmonary arterial pressure between the two groups was not significant. The pulmonary capillary-wedged pressure and systemic blood pressure did not change significantly after intravariceal injection of alcohol. Absolute alcohol in the amount usually used for sclerotherapy has minimal and transient effects on pulmonary hemodynamics and, in this respect, it appears to be a relatively safe sclerosant.

Endoscopic sclerotherapy for varices in children.

Thirty-one children with variceal bleeding due to portal hypertension (extrahepatic obstruction 19, non-cirrhotic portal fibrosis five, and cirrhosis of liver seven patients) were treated with endoscopic sclerotherapy with absolute alcohol. Acute variceal bleeding was successfully controlled in 10 patients by emergency sclerotherapy. A 3 weekly schedule of sclerotherapy could achieve obliteration of varices in all the patients. The mean (+/- SD) number of sclerotherapy courses and the time required for variceal eradication was 4.5 +/- 1.7 and 14.4 +/- 3.9 weeks, respectively. During a mean follow-up of 23.3 +/- 11.4 months, variceal recurrence was seen in three (9.7%) patients, two with cirrhosis and one with noncirrhotic portal fibrosis. Recurrence was not seen in any patient with extrahepatic obstruction. Five (16.1%) patients had a rebleed that could be controlled with emergency sclerotherapy. Esophageal stricture developed in four (12.9%) patients and could be dilated easily in all of them. The other complications of sclerotherapy included retrosternal pain, dysphagia, and fever; these were mild and short lasting. Survival in patients with extrahepatic obstruction and noncirrhotic portal fibrosis was 100%. The only death was in a cirrhotic, who died due to terminal hepatic failure. In conclusion, endoscopic sclerotherapy can be recommended as a safe and effective treatment in children for the control of acute variceal bleeding and for variceal obliteration.

Corrosive oesophageal strictures following acid ingestion: clinical profile and results of endoscopic dilatation.

There are several reports on oesophageal strictures caused by alkali ingestion, but information on oesophageal strictures due to acid ingestion is scarce. Endoscopic dilatation, which has been found to be quite safe and effective in the treatment of benign oesophageal strictures of other aetiology, has also not been evaluated adequately in the treatment of these strictures. Over a period of 2 years, of 47 patients treated at this centre of benign oesophageal strictures, 17 (36.2%) patients had strictures following ingestion of corrosive agents. Thirteen patients had ingested acids and only four gave a history of alkali ingestion. The age range of these 13 patients was 14-50 years (mean = 25.5 years, s.d. = 2.6). The amount of acid ingested varied from 10 to 100 ml (median = 50 ml). The interval between acid ingestion and presentation to hospital ranged from 1 to 60 months (median = 2 months). Ten patients had multiple strictures, and the most common site of involvement was the upper third followed by the lower third of the oesophagus. Only five of these 13 patients had evidence of gastric involvement in the form of antral stricture (four) and hour glass deformity (one). Strictures were dilated using Eder-Puestow metal olives passed over a guide wire. The total number of sittings required to achieve adequate dilatation in this group ranged from 1 to 30 (median = 14). Most patients were managed successfully with dilatation (good response 63.6%, satisfactory response 18.2%). On follow-up, recurrence of dysphagia was seen in a high number of patients (66%), but this could be managed easily with repeat dilatation.(ABSTRACT TRUNCATED AT 250 WORDS)

Immunological profile of patients with non-cirrhotic portal fibrosis.

The aetiopathogenesis of non-cirrhotic portal fibrosis (NCPF), a common cause of portal hypertension in India, is not known. To study the immune status of NCPF patients and to see whether immunological mechanisms have a role to play, humoral and cell-mediated immunological studies were carried out in 43 patients with NCPF and compared with equal number of matched healthy controls and 31 patients with compensated liver cirrhosis. Serum immunoglobulin A (IgA) and complement (C3, C4) levels were significantly (P less than 0.001) lower in NCPF patients compared with controls and cirrhotics. There was no significant difference between the total or the relative concentration of the immunoglobulins and complements between NCPF patients and healthy controls, but, in patients with cirrhosis, concentration of all the immunoglobulins was higher. The cutaneous response to dinitrochlorobenzene was poorer in patients with NCPF, but the difference between cirrhotics and controls was not significant. A decrease in the suppressor/cytotoxic (T8) phenotype of lymphocytes in the peripheral blood and an increase in the ratio of helper/inducer (T4) and T8 lymphocytes was seen in patients with NCPF and cirrhosis. Although these results indicate definite immunological abnormalities in NCPF patients, their role in the pathogenesis of NCPF remains to be investigated.

Characterization of peripheral blood lymphocytes in patients with non-cirrhotic portal fibrosis: a comparison with cirrhotics and healthy controls.

Non-cirrhotic portal fibrosis (NCPF) is a common cause of portal hypertension in India. Its aetiopathogenesis is not well understood. To investigate the possibility of an immune mediated injury, phenotypes of peripheral blood lymphocytes were studied in 15 NCPF patients and were compared with an equal number of compensated cirrhotics and matched healthy controls. The population of total peripheral T lymphocytes (T1) and suppressor/cytotoxic phenotype (T8) was significantly (P less than 0.01) decreased in NCPF patients compared with controls. The sub-populations of helper/inducer lymphocytes (T4) and total B lymphocytes, however, were comparable with controls. The ratio of T4 to T8 lymphocytes was significantly (P less than 0.01) increased in NCPF patients in comparison with controls. Similar changes in the lymphocyte population were also observed in cirrhotic patients. Further investigations are required to identify whether the cellular alterations seen in NCPF have a pathogenetic basis or are secondary to the disease process itself.

Fine needle aspiration cytologic appearance of inflammatory pseudotumor of the liver. A case report.

BACKGROUND: Inflammatory pseudotumor (IPT) is a rare space-occupying lesion of the liver that can be clinically confused with a malignant process. CASE REPORT: A 28-year-old male presented with fever and a palpable, firm liver. Ultrasonography and computed tomography revealed a mass in the right lobe of the liver. Fine needle aspiration biopsy (FNAB) under ultrasonographic guidance showed inflammatory cells, fibroblasts and a few hepatocytes. A diagnosis of inflammatory pseudotumour was suggested and confirmed on a true-cut biopsy. CONCLUSION: The cytologic appearance of IPT is characteristic. FNAB under ultrasonographic is a quick and easy technique for its diagnosis and differentiation from malignant space-occupying lesions.

Blood transfusion practices in India: results of a national survey.

BACKGROUND: Blood transfusion may lead to serious clinical consequences for the recipient, if the transfused blood is not safe. To assess the functioning of the blood banks in India, a nation-wide, questionnaire-based study was conducted between November 1995 and November 1996 under the auspices of the Indian Association for Study of the Liver. METHODS: Of 604 blood banks in 31 states and union territories to whom the questionnaires were sent, responses wereobtained from 78 (13%) blood banks in 17 (54.8%) states, providing information on 275,000 donors. RESULTS: A majority (58%) of donors in these blood banks were replacement donors, followed by voluntary (39.3%) donors. About 87% of the respondent blood banks screen blood for hepatitis B, 95% for HIV, 94% for syphilis, 67% for malaria, and only 6% for hepatitis C. Marked heterogeneity in the test methods was observed with only 13% using ELISA kits for HBsAg. Only 21% of the blood banks prepare blood-derived components. Feedback to the blood banks on the occurrence of transfusion-associated hepatitis is given on less than 40% of occasions. CONCLUSIONS: Testing for transfusion-transmitted infections is unsatisfactory and poorly regulated in India. Reporting of adverse events after transfusion is poor and no stringent donor deferral system exists.

Histological comparison of chronic hepatitis B and C in an Indian population.

Many studies have shown that steatosis, lymphoid aggregates or follicles and bile duct injury on histology are more consistently associated with chronic hepatitis C than chronic hepatitis B. We compared liver biopsies of 30 patients of chronic hepatitis B with an equal number of age matched patients with chronic hepatitis C. Steatosis, lymphoid aggregates or follicles and bile duct injury were noted in 66.6%, 36.6% and 26.6% cases respectively of chronic hepatitis B as compared to 70%, 33.3% and 30% cases respectively of chronic hepatitis C. Thus none of the features were considered distinctive of HCV infection.
