title: Effect of sucralfate granules in suspension on endoscopic variceal sclerotherapy induced ulcer: analysis of the factors determining ulcer healing.
abstract: Oesophageal ulcers commonly occur after endoscopic variceal sclerotherapy and usually cause complications and a delay in further sclerotherapy. The aims of this study are to investigate the effect of sucralfate granules in suspension on the treatment of endoscopic variceal sclerotherapy induced ulcer and analyse the factors determining the ulcer healing. Fifty-two patients with oesophageal variceal bleeding received elective endoscopic variceal sclerotherapy. After endoscopically proved oesophageal ulcers, they were randomized to receive either sucralfate granules in suspension (n = 22) or antacid (n = 23). Follow-up endoscopy was performed weekly. Ulcer healing rates were compared between the groups using the log-rank test. Forty-one ulcers receiving sucralfate and 48 ulcers receiving antacid treatment were evaluated. The clinical characteristics of the ulcers were similar in both groups. The ulcers in patients receiving sucralfate healed faster than those receiving antacid (P<0.02). On analysis of factors affecting ulcer healing, ulcers smaller than 1 cm2 (n = 59) appeared to heal faster than those larger than 1 cm2 (n = 30; P= 0.059) and shallow ulcers (n = 46) healed faster than deep ulcers (n = 43; P<0.001). On multifactorial analysis, ulcer depth was the only factor determining ulcer healing. The ulcer healing effects of sucralfate became more prominent when the ulcer was larger than 1.0cm2 (1.7+/-0.6 weeks vs 2.3+/-0.6 weeks, P= 0.011) and deep (1.7+/-0.7 weeks vs 2.5+/-1.0 weeks, P= 0.013) when compared with those receiving antacid. Sucralfate granules in suspension speed the healing of endoscopic variceal sclerotherapy induced ulcer, especially deep and large ulcers.
