Summary

There were many approaches for patients with obscure gastrointestinal bleeding (OGIB). Capsule endoscopy (CE), double-balloon endoscopy, deep small-bowel spiral enteroscopy, laparoscopy, computed tomography and angiography have been recommended as investigation. However, of these techniques, the evaluation and management of patients with OGIB remains a formidable challenge. We compared the diagnostic yield and long-term outcomes of patients with OGIB randomized to angiogram combination laparoscopy or angiogram alone.

Detailed description

Consecutive patients who presented with OGIB to the second people's hospital of GuangDong province between January 2003 and November 2008 were recruited. This study was approved by the ethical committee of the Second people's Hospital of GuangDong Province and was designed according to the CONSORT (Consolidated Standards of Reporting Trials) guidelines. All patients gave written informed consent before beginning the study. As a standard protocol, all patients presented with melena or hematochezia would receive at least 2 times upper gastrointestinal endoscopy before admission. Patients who had nondiagnostic upper GI endoscopy were also offered at least 2 times colonoscopy before admission. All gastrointestinal endoscopies were performed by experienced endoscopists (hanning Wang). OGIB were defined as patients who had nondiagnostic upper endoscopy and colonoscopy. Patients who were \< 18 years, pregnant, in moribund conditions, or with terminal malignancy were excluded. Patients with contrast allergy and impaired renal function (serum creatinine \> 150 µmol/l) were also not eligible for this study. All patients were randomized to receive either mesenteric angiography alone or angiography combination laparoscopy in a 1:1 ratio. Randomization was performed computer-generated list using a randomly permuted block design. To ensure concealed randomization, the randomization code was put in opaque envelope and kept by researchers not performing angiography or angiography combination laparoscopy. Both patients and investigators were unaware of the randomization sequence.
