[Esophageal stenosis due to a dissecting intramural hematoma following the endoscopic sclerotherapy of esophageal varices].

The dissecting intramural hematoma of the esophagus (DEH) is a rare complication of endoscopic variceal sclerotherapy (EVS). We present a 37 years male with Laennec's cirrhosis who developed a submucosal hematoma with complete obstruction of the esophagus 24 h. after the second session of EVS diagnosed by endoscopy. After conservative treatment the patient recovered well with complete resolution of the lesion. The review of the literature shows no correlation between DEH and type or volume of sclerosant, site of injection or previous number of sessions. Unknown in children. Most of these patients had abnormal hemostasis. We have performed EVS in 227 patients (879 sessions), with only a case of DEH (rate 0.13%). In this case the bad tolerance and movements during of EVS were very important.
