Pantoprazole before Endoscopy in Patients with Gastroduodenal Ulcer Bleeding: Does the duration of Infusion and Ulcer Location Influence the Effects?

The aim of this study was to investigate the effect of preemptive pantoprazole infusion on early endoscopic findings in patients with acute ulcer bleeding. Records of 333 patients admitted with acute ulcer bleeding were analyzed. Ulcer bleeders were given either 80 mg bolus of pantoprazole followed by continuous infusion of 8 mg per hour or saline infusion until endoscopy. In 93 patients saline infusion whereas in 240 patients bolus plus infusion of pantoprazole was administrated with mean (±SD) durations of 5.45 ± 12.9 hours and 6.9 ± 13.2 hours, respectively (P = 0.29). Actively bleeding ulcers were detected in 46/240 (19.2%) of cases in the pantoprazole group as compared with 23/93 (24.7%) in the saline infusion group (P = 0.26). Different durations of pantoprazole infusion (0-4 hours, >4 hours, and >6 hours) had no significant effect on endoscopic and clinical outcome parameters in duodenal ulcer bleeders. Gastric ulcer bleeders on pantoprazole infusion longer than 4 and 6 hours before endoscopy had actively bleeding ulcers in 4.3% and 5% compared to the 19.5% active bleeding rate in the saline group (P = 0.02 and P = 0.04). Preemptive infusion of high-dose pantoprazole longer than 4 hours before endoscopy decreased the ratio of active bleeding only in gastric but not in duodenal ulcer patients.

[The value of routine second-look endoscopy in the management of acute gastroduodenal ulcer bleeding]. / A tervezett ellenôrzô endoszkópia értéke az akut gastroduodenalis fekélyvérzés ellátásában.

UNLABELLED: The role of routine second-look endoscopy in the management of patients with acute peptic ulcer bleeding is controversial. A more precise identification of higher risk patient group, based on both clinical and endoscopic criteria, is needed to determine whether there are high-risk patients who may benefit from this management strategy. AIM: Or aim was to find out whether scheduled second-look endoscopy has any beneficial effect in the clinical outcome. METHODS: Both endoscopic and clinical data were analyzed in 274 acute gastroduodenal ulcer bleeding patients. The need for repeated endoscopic haemostatic intervention was used as a measure to evaluate the potential beneficial effect of the second look endoscopy. Patients were categorized according to the Forrest classification detected during the emergency endoscopy. RESULTS: In the subgroup of actively bleeding patients (Forrest Ia, Ib) a second endoscopic haemostasis was performed in 23.8% of cases. In the patient subgroup with visible vessel ulcers (Forrest IIa) and in those with adherent clot covered ulcers (Forrest IIb) the needs for a repeated haemostasis were 13.0% and 13.3% respectively. Despite the not statistically significant differences, remarkable clinical impact was noted favoring scheduled second look endoscopy in patients with initially active ulcer bleeding. CONCLUSION: In the light of the retrospective study results it may be concluded that the scheduled second look endoscopy strategy offers a beneficial clinical outcome for selected patients estimated to be a very high risk of re-bleeding following the initial endoscopic therapy for active bleeding.
