Evaluation of the incidence and significance of the "mosaic pattern" in patients with cirrhosis, noncirrhotic portal fibrosis, and extrahepatic obstruction.

Mosaic pattern of gastric mucosa has been reported to be a sensitive and specific criterion for the diagnosis of portal hypertension and an important marker of nonvariceal upper gastrointestinal bleeding. So that the validity of this endoscopic sign could be assessed, 136 patients with portal hypertension, 25 chronic alcoholics without portal hypertension, and 366 controls were carefully endoscoped. Mosaic pattern was significantly (p less than 0.01) more common in portal hypertension patients (7.4%) than in controls (1.4%). It was not seen in chronic alcoholics. The incidence of mosaic pattern was 10.9% in cirrhotics, 2.9% in noncirrhotic portal fibrosis, and 5.4% in extrahepatic portal obstruction patients; the differences were not significant. Mosaic pattern was significantly (p less than 0.01) more often seen in postsclerotherapy (13.8%) than in presclerotherapy patients (2.6%). Bleeding from nonvariceal causes was uncommon, and was seen in only one patient (0.8%) showing mosaic pattern. Endoscopic gastric biopsies from areas showing mosaic pattern did not reveal any vascular abnormalities. In conclusion, gastric mucosal lesions are not very common in Indian patients with portal hypertension. In our experience, "mosaic pattern" is not a useful diagnostic feature in portal hypertension patients.

Ethanolamine oleate versus absolute alcohol as a variceal sclerosant: a prospective, randomized, controlled trial.

Forty-seven patients with esophageal variceal bleeding were randomly allocated to undergo sclerotherapy on a 3 weekly schedule with either 5% ethanolamine oleate (23 patients) or absolute alcohol (24 patients), in an attempt to compare the efficacy and safety of the two sclerosants. Sclerotherapy with absolute alcohol eradicated esophageal varices significantly earlier compared with ethanolamine oleate (12.9 +/- 5.2 vs 22.3 +/- 8.2 wk, respectively, p less than 0.001). The mean number of injection courses and the mean amount of sclerosant required for variceal obliteration was also significantly (p less than 0.001) less in the alcohol-injected group. Although the total number of rebleeding episodes were significantly (p less than 0.05) less in the alcohol-injected group, the frequency of rebleeding was not significantly different between the two groups (20.8% vs 30.4%, respectively, p greater than 0.05). Two (8.1%) patients died due to rebleeding in the ethanolamine-injected group, whereas in the alcohol group, none died. There was no significant difference in the frequency of complications with the two sclerosants. Besides the relative ease of rapid injection due to its aqueous nature, alcohol is readily available and relatively economical (total cost of sclerosant per patient; alcohol US $0.50, ethanolamine US $60). In conclusion, absolute alcohol appears to be a useful alternative to 5% ethanolamine oleate as a variceal sclerosant.

Intravariceal versus paravariceal sclerotherapy: a prospective, controlled, randomised trial.

Fifty four consecutive patients with oesophageal variceal bleeding were randomised to undergo intravariceal (28 patients) or paravariceal (26 patients) sclerotherapy, every three weeks. Intravariceal technique was found significantly (p less than 0.01) more effective in controlling active variceal bleeding than the paravariceal technique (91% v 18.7% respectively). The mean (+/- SD) time taken for variceal eradication by intravariceal sclerotherapy (15.4 +/- 5.3 weeks) was significantly (p less than 0.001) less than paravariceal (26.8 +/- 6.6 weeks) technique. The number of sclerotherapy sessions needed with intravariceal technique were also significantly less. Rebleeding was seen in 38.5% patients after para and 14.3% after intravariceal injections (NS). Except for retrosternal pain, which occurred more often (p less than 0.01) with paravariceal technique, there was no difference in the incidence of other complications or mortality between the two groups. Variceal recurrence was seen in seven patients (25%) in the intra and one (3.9%) patient in the paravariceal group (p less than 0.01) after a mean follow up of 29.4 +/- 9.1 weeks. Intravariceal sclerotherapy was superior to paravariceal in the control of active variceal bleeding and for total variceal obliteration, but was associated with a higher variceal recurrence.
