The Effect of Second Look Endoscopy in Patients with Peptic Ulcer Bleeding / 대한소화기내시경학회지

ABSTRACT

BACKGROUND/AIMS: Performing second look endoscopy has been suggested in order to reduce recurrent bleeding. We assessed whether second look endoscopy reduces the risks of recurrent bleeding and the mortality rate for patients suffering with peptic ulcer bleeding. METHODS: From February 2003 to June 2004, we have performed a prospective, randomized, controlled study of 141 patients with bleeding peptic ulcers, and these patients had been admitted to Kyungpook National University Hospital. Seventy patients in the study group were randomized to receive scheduled second look endoscopy. Seventy one patients in the control group were observed closely. RESULTS: Seventeen of the admitted 141 patients were found to have rebleeding after initial therapeutic endoscopy. The overall rebleeding rate was 12.1%. Although the duration of the hospital stay was significantly lower for the study group than for the control group (p<0.05), the rebleeding rate was similar for both groups (p<0.05). The two groups were similar in respect to the mortality during the period of hospitalization, the volume of hypertonic saline epinephrine that was injected and the number of hemoclips that were used. CONCLUSIONS: From these results, we can conclude that scheduled second look endoscopy with retreatment did not reduce the risk of recurrent bleeding for patients with peptic ulcer bleeding. Therefore, scheduled second look endoscopy should be selectively performed for the patients who are at a high risk for peptic ulcer bleeding.
