    Abstract:
    We report the case of 4 male patients, smokers, with alcoholic cirrhosis, mean age 54.7 +/- 6 years, treated by sclerotherapy for bleeding esophageal varices. Variceal eradication was obtained following juxtacardial intravariceal injection of 1.5 p. 100 polidocanol in one case (100 ml), and 0.5 p. 100 polidocanol in 3 cases (90, 240 and 310 ml). Local complications were observed in all patients (ulcers: 3; stenosis: 1). Carcinoma of the lower third of the esophagus was detected 12, 20, 22 and 30 months after esophageal sclerosis. Carcinoma was circular (one case), semicircular (2 cases), and nodular superimposed on Barrett's esophagus (one case). Histologic features included squamous cell carcinoma in 3 cases and adenocarcinoma in one case. Sclerotherapy could lead to the development of carcinoma because of mucosal alterations. However, other high risk factors (age, alcohol-tobacco intoxication, Barrett's esophagus) and different histologic features suggest a causal association. Endoscopic follow-up of patients after esophageal sclerosis could confirm this hypothesis.
