Ulcers after intravariceal sclerotherapy: correlation of symptoms and factors affecting healing.

Esophageal variceal ulcers have been held responsible for most postsclerotherapy complaints. To investigate a possible relation between these ulcers and symptoms, we followed for 4 weeks 40 patients with portal hypertension who had received a single course of intravariceal sclerotherapy. All 40 patients were found to have mucosal variceal ulcers on the day after sclerotherapy. One or more symptoms were given by 26 (65%) patients; dysphagia by 53% (mean duration 4.6 +/- 2.2 days), retrosternal pain by 28% (mean duration 3.0 +/- 2.5 days), and fever by 15% (mean duration 2.1 +/- 0.4 days). A gastric variceal ulcer was responsible for bleeding in one (2.2%) patient. We found no correlation between the occurrence and duration of symptoms and the presence of variceal ulcers. While symptoms were transient, ulcers persisted for several days to weeks in most patients. Patients who had received a higher amount of sclerosant developed larger ulcers (greater than 1 cm) with more symptoms and healing was more delayed than in those who had received lesser amounts and developed smaller ulcers (less than 1 cm). In patients with a serum albumin level greater than 3.0 g/dl, ulcers healed more often than in those with a less than 3.0 g/dl albumin (72 versus 18%, p less than 0.05). Development of mucosal ulcers is a natural consequence of intravariceal sclerotherapy and it appears unrelated to symptoms. The chemical nature and the volume of the injected sclerosant are probably responsible for the symptoms after sclerotherapy. Further, postsclerotherapy ulcers heal spontaneously, more often in patients with good nutritional status.
