Laproscopic treatment for small bowel bleeding after detection by double-balloon endoscopy: A case report.

Introduction: The frequency of small bowel bleeding is relatively low and the process for the diagnosis and treaVtment remains difficult. Here, we report a case of massive small bowel bleeding due to arteriovenous malformation (AVM), treated by a combination of double-balloon endoscopy and laparoscopic resection.
Presentation of Case: A 59-year-old man was admitted to our hospital due to a hemorrhagic stool. The patient presented transient hemorrhagic shock and contrast-enhanced CT revealed a hyper-vascularized tumor in the small bowel. India ink tattooing for the responsible lesion with double-balloon endoscopy was performed. The tattooed lesion was easily confirmed during the subsequent laparoscopic observation and segmental resection was done. Pathological examination showed arteriovenous malformation of the small bowel.
Discussion: Prior to laparoscopic resection, the localization of the responsible area might be a significant consideration when the lesion is invisible. Endoscopic marking with DBE enables intraluminal detection and laparoscopic observation from the serosal side.
Conclusion: Preoperative marking with the use of double-balloon endoscopy followed by laparoscopic resection might be an optimal option for the treatment of massive small intestinal bleeding.
