Brief Summary

The purpose of this prospective study is to identify risk factors which could predict poor fading of SRH or early recurrent bleeding of peptic ulcer hemorrhage after successful endoscopic hemostasis and high-dose PPI infusion. These risk factors will be the selection criteria for patients who are indicated to receive second-look endoscopy.

Detailed Description

Peptic ulcer bleeding is a common disease, and recurrent bleeding is an independent risk factor leading to mortality. The appearance of stigmata of recent hemorrhage (SRH) indicates possible recurrence of peptic ulcer bleeding, for which the likelihood decreases over the course of 3-6 days. In addition to endoscopic evidences illustrating the SRH, patients with co-morbidities have a higher risk of recurrent bleeding.

Patients with co-morbidities have not only higher recurrent bleeding rates during the first 3 days but also higher delay recurrent bleeding after 3-day proton pump inhibitor (PPI) infusion than those without. More than 50% recurrent bleeding develops after 3-day PPI infusion among patients with end stage renal diseases. Although endoscopic treatment plus a 72-hour intravenous PPI infusion and followed by oral PPI has already been adopted as a standard treatment in peptic ulcer bleeding currently, several studies showed limited effectiveness of such treatment for high risk patients. The reasons may be because lesions of SRH were not completely faded after initial treatment including endoscopic hemostasis and intravenous PPI infusion. Thus, it is an important issue to improve such high recurrent bleeding risk for these patients.

Endoscopic treatment plus a 72-hour intravenous PPI infusion is the standard protocol for treatment of peptic ulcer bleeding. Moreover, several studies have shown that PPI treatment could decrease the presentation of SRH. However, there were insufficient data to validate the efficacy of such standard treatment to fade the SRH, especially among high risk patients. Therefore, several studies looked at the efficacy of routine second-look endoscopy, defined as scheduled repeat endoscopy after primary endoscopic hemostasis in patients at high risk of rebleeding. However, the role and the selection criteria for patients who require second-look endoscopy remains uncertain. There is a pressing need to elucidate the role of second-look endoscopy in these patients.

Hence, the purpose of this prospective study is to identify risk factors which could predict poor fading of SRH or early recurrent bleeding of peptic ulcer hemorrhage after successful endoscopic hemostasis and high-dose PPI infusion. This data will show the originality and clinical importance to identify the selection criteria for patients who are indicated to receive second-look endoscopy.

Conditions

Peptic Ulcer Hemorrhage

Study Design

• Observational Model Type: CASE_CONTROL
• Study Time Perspective: PROSPECTIVE

Study Groups

The High risk group

Each enrolled patient receives an 80 mg loading dose of intravenous esomeprazole or pantoprazole immediately after successful endoscopic hemostasis. Patients then receive a 3-day continuous high dose (8 mg per hour) of esomeprazole or pantoprazole infusion.

Patients are defined in the high risk group if they still have major stigmata of recent hemorrhage at the second-look endoscopy or have early recurrent bleeding before the schedule time for follow-up.

Recurrent bleeding is defined as: 1) continuous melena, hematochezia, or the presence of recurrent bloody aspirates through a nasogastric tube and 2) relapse of hemodynamic instability, including systolic blood pressure <90 mmHg, heart rate >120 beats per minute, or a drop in hemoglobin concentration by more than 2 g/dL.

esomeprazole or pantoprazole

Intervention Type: DRUG

Each enrolled patient receives an 80 mg loading dose of intravenous esomeprazole (Nexium®, AstraZeneca AB, Södertälje, Sweden) immediately after hemostasis is achieved spontaneously or by gastroscopy. Patients then receive a 3-day continuous high dose (8 mg per hour) of esomeprazole infusion. Because of concern for patient safety with certain drug-drug interactions, patients who take clopidogrel receive intravenous pantoprazole (Pantoloc®, Takeda, Singen, Germany), including an 80 mg loading dose and a 3-day continuous high-dose (8 mg/h) of infusion.

Endoscopic hemostasis

Intervention Type: PROCEDURE

At the index gastroscopy, bleeding ulcers are checked. If the adherent clot is found over the ulcer base, it will be vigorously washed away with water jet. All of the stigmata of recent hemorrhage (SRH) are treated by one or a combination of endoscopic therapies including local injection of diluted epinephrine 1:10000, bipolar heated probe at 20 J per goal consecutively until achievement of coaptive coagulation, argon plasma coagulation, band ligation, or hemoclip therapy. The success of endoscopic hemostasis is defined as cessation of bleeding together with achievement of cavitation at the vessel after application of the heater probe.

The control group

Each enrolled patient receives an 80 mg loading dose of intravenous esomeprazole or pantoprazole immediately after successful endoscopic hemostasis. Patients then receive a 3-day continuous high dose (8 mg per hour) of esomeprazole or pantoprazole infusion.

Patients are defined in the control group if they does not have recurrent bleeding before the schedule time for follow-up, and have only minor stigmata of hemorrhage or clean ulcer base at the second-look endoscopy.

Recurrent bleeding is defined as: 1) continuous melena, hematochezia, or the presence of recurrent bloody aspirates through a nasogastric tube and 2) relapse of hemodynamic instability, including systolic blood pressure <90 mmHg, heart rate >120 beats per minute, or a drop in hemoglobin concentration by more than 2 g/dL.

esomeprazole or pantoprazole

Each enrolled patient receives an 80 mg loading dose of intravenous esomeprazole (Nexium®, AstraZeneca AB, Södertälje, Sweden) immediately after hemostasis is achieved spontaneously or by gastroscopy. Patients then receive a 3-day continuous high dose (8 mg per hour) of esomeprazole infusion. Because of concern for patient safety with certain drug-drug interactions, patients who take clopidogrel receive intravenous pantoprazole (Pantoloc®, Takeda, Singen, Germany), including an 80 mg loading dose and a 3-day continuous high-dose (8 mg/h) of infusion.
