Improved survival following injection sclerotherapy for esophageal varices: Final analysis of a controlled trial
David Westaby, Brian R. D. Macdougall, Roger Williams – 1 September 1985 – Long‐term follow‐up (median: 37 months; range: 19 to 68) of the 116 patients (56 sclerotherapy, 60 control group) entered into a controlled trial of endoscopic variceal sclerotherapy has shown a total of 18 deaths in the sclerotherapy group, including five from variceal bleeding compared with 32 deaths in the control group (p < 0.01), of which 25 were from variceal hemorrhage (p < 0.001). Survival as assessed by cumulative life analysis was significantly better in those treated by sclerotherapy (p < 0.001).
