Background: Dieulafoy's lesion is an important cause of GI bleeding. The results of hemoclip application as the first treatment of choice for Dieulafoy's lesions have not been reported. This study prospectively examined the short- and long-term outcomes of hemoclip application for Dieulafoy's lesions.
Methods: The study was conducted over a 7-year period beginning in January 1995 during which hemoclip application was used as the first-choice hemostatic treatment for Dieulafoy's lesions. Clinical data, endoscopic findings, and outcome of treatment were evaluated. Long-term outcome for patients was also investigated.
Results: A Dieulafoy's lesion was diagnosed in 34 patients (27 men, 7 women; mean age, 54 years, range 21-81 years) after a mean of 1.2 endoscopies; 79.4% of the patients had active bleeding. Initial hemostasis was attained by hemoclip placement in 94.1%. The rate of recurrent bleeding was 9.3%. No patient required additional treatment such as surgery. The 30-day mortality rate was 2.9% (1 death, unrelated). For the remaining 33 patients, median follow-up was 53.8 months (range 19 to 90 months). Another Dieulafoy's lesion developed in one patient during follow-up, but in a different location compared with the index lesion.
Conclusions: Endoscopic hemoclip application for Dieulafoy's lesions was effective and safe with short- and long-term benefits.
