Insights
Diagnosing small bowel bleeding from a jejunal diverticulum is challenging. Angiography and microcatheter techniques successfully located and marked the bleeding site for surgical management.
Area of Science:
- Gastroenterology
- Interventional Radiology
- Surgical Diagnosis
Background:
- Accurate localization of small bowel hemorrhage is critical for effective patient management.
- Emergency surgical intervention for small bowel bleeding can be complicated by the difficulty in precisely locating the bleeding source.
Observation:
- A rare case of digestive hemorrhage originated from a jejunal diverticulum.
- Diagnostic angiography was employed to identify the bleeding lesion within the jejunum.
Findings:
- Angiography successfully diagnosed the jejunal diverticulum as the source of bleeding.
- A microcatheter was precisely guided to the bleeding site for targeted intervention.
Implications:
- This case highlights the utility of angiography in diagnosing obscure gastrointestinal bleeding.
- Intraoperative methylene blue staining, guided by microcatheter placement, can aid surgeons in lesion identification and resection.
Abstract:
Localization of digestive hemorrhage is essential for the management of this entity. However, management is difficult in the small bowel, where emergency situations are rare but may require surgery without precise location of the lesion. We present a case of hemorrhage caused by jejunal diverticulum diagnosed by angiography. A highly selective microcatheter was placed in the bleeding site to achieve staining of the lesion with intraoperative methylene blue.
