A prospective clinical, endoscopic, and histopathologic study of the esophagus was carried out in 24 patients with advanced liver disease who underwent esophageal variceal sclerotherapy (EVS) and who eventually came to autopsy. Patients were arbitrarily divided into three groups: acute (group I), intermediate (group II), and chronic (group III) based on the interval between the first EVS and death. EVS with sodium tetradecyl sulphate (STS) initially produced thrombosis with varying degrees of necrosis and inflammation followed by ulceration, recanalization, and eventually fibrosis with obliteration of varices. Recurrent variceal hemorrhage (VH) leading to death was highest in the acute group since all patients died of uncontrollable VH (100%); it ranged between 50–60% in both the intermediate and chronic groups. Despite variceal obliteration, recurrent hemorrhage developed in the chronic group due to gastric varices or other venous channels in the esophagus or stomach. Additionally, we describe findings not previously reported, such as the presence of sclerosant outside the varices after intravariceal injection, thrombosis of gastric varices after esophageal injections, and the development of muscular wall thickening.
