Background: The Dieulafoy lesion is an important cause of gastrointestinal (GI) hemorrhage. Optimal treatment and long-term outcome are unknown. This study aimed to characterize the presentation of the Dieulafoy lesion and to summarize the results and report the long-term outcome of endoscopic therapy., Methods: Data regarding diagnosis, treatment and outcomes were derived from our GI Bleed Team database, patient records and follow-up correspondence., Results: Ninety Dieulafoy lesions were identified in 89 patients after a mean of 1.9 endoscopies. Their mean age was 72 years. Thirty-four percent of lesions were extragastric. Median transfusion requirement was 5 units. Two patients exsanguinated and 3 required surgery; all others were initially successfully treated endoscopically (with or without epinephrine injection): heat probe (71 patients), band ligation (3), hemoclip (1), laser (2), bipolar probe (4), sclerotherapy (2) and epinephrine alone (2). Gastric perforation occurred in 1 patient following sclerotherapy. Thirty-day mortality was 13%, 4 related to hemorrhage and 5 related to comorbidity. During median follow-up of 17 months, 34 patients (42%) died. One patient had recurrent bleeding 6 years after operation., Conclusions: Dieulafoy lesion is relatively common and often extragastric. Endoscopic therapy is safe and effective. Long-term recurrence was not evident following endoscopic ablation. Follow-up after ablative therapy appears unnecessary.

Objective: To summarize the results of endoscopic therapy for acute hemorrhage from gastroduodenal malignant lesions., Design: The 3-year experience (1989 through 1991) of a specialized gastrointestinal (GI) bleeding team in the endoscopic treatment of acute upper GI bleeding from gastroduodenal malignant tumors was retrospectively reviewed., Material and Methods: Of 1,083 consecutive patients with acute major upper GI hemorrhage, 21 (1.9%) were found to have advanced tumors of the stomach and duodenum, 15 of whom received endoscopic therapy. In this study group of 15 patients, the tumors were gastric in 11 and duodenal in 4. Endoscopic treatment consisted of injection of epinephrine, heater probe coagulation, neodymium:yttrium-aluminum-garnet laser coagulation, or injection of sodium tetradecyl sulfate., Results: Initial endoscopic hemostasis was achieved in 10 of the 15 patients (67%); however, bleeding recurred in 8 of 10 (80%), and all 5 in whom endoscopic hemostasis was not achieved continued to bleed. Mean transfusion requirements for the 30 days before and the 30 days after the first endoscopic treatment were 7.6 and 6.4 units of packed erythrocytes, respectively (P > 0.10). Five major procedure-related complications occurred, two of which were fatal. The median duration of survival after the first endoscopic treatment was 39 days (range, 1 to 1,414)., Conclusion: In patients with major bleeding from advanced gastroduodenal malignant lesions, endoscopic therapy seems to provide limited benefit.
