Intraoperative transillumination with water-filling of lumen for localizing lesions in occult small bowel bleeding

Preoperative and intraoperative localisation of gastrointestinal bleeding of obscure origin.

In the past six years, 37 patients with gastrointestinal bleeding of obscure origin had their bleeding sites localised preoperatively or intraoperatively. Preoperative investigations followed a regime consisting of endoscopy, barium meal and follow through, small bowel enema, 99mTc pertechnetate scan, 99mTc-labelled red blood cell scan and selective coeliac and mesenteric angiography. Bleeding ...

A new view of occult and obscure gastrointestinal bleeding.

Occult gastrointestinal bleeding usually is discovered when fecal occult blood test results are positive or iron deficiency anemia is detected. Fecal occult blood testing methods vary, but all have limited sensitivity and specificity. The initial work-up for occult bleeding typically involves colonoscopy or esophagogastroduodenoscopy, or both. In patients without symptoms indicating an upper ga...

Practical Lessons from the Small Bowel Bleeding Lesions: A Case Report on Small Bowel Cavernous Hemangioma

Is Occult Obscure Gastrointestinal Bleeding a Definite Indication for Capsule Endoscopy? A Retrospective Analysis of Diagnostic Yield in Patients with Occult versus Overt Bleeding

Background/Aim. Usefulness of capsule endoscopy (CE) for diagnosing small-bowel lesions in patients with obscure gastrointestinal bleeding (OGIB) has been reported. Most reports have addressed the clinical features of overt OGIB, with few addressing occult OGIB. We aimed to clarify whether occult OGIB is a definite indication for CE. Methods. We retrospectively compared the cases of 102 patient...

Angiodysplasia of the small bowel; a 'brilliant' technique for localizing the quiescent lesion.

Intraoperative transluminal endoscopic illumination is of benefit to locate angiodysplasias of the small bowel at laparotomy in the quiescent non-bleeding phase.
