title: Laparoscopy-assisted exploration of obscure gastrointestinal bleeding after capsule endoscopy: the Korean experience.
abstract: BACKGROUND
  Obscure gastrointestinal bleeding (OGB) is generally defined as recurrent acute or chronic bleeding for which no source has been identified by routine radiologic and endoscopic examination. The aim of this study was to report our early experiences detecting small bowel bleeding by capsule endoscopy (CE) and the results of laparoscopy assisted surgery for OGB.
  
  
  METHODS
  Seventy-five patients with OGB were examined by CE. Twelve of 24 patients in the active bleeding group underwent laparoscopic or laparoscopy assisted surgery and we carried out intraoperative enteroscopy to find the focus of the bleeding.
  
  
  RESULTS
  Laparoscopic localization of the lesion was successful for 4 patients-those with Meckel's diverticulum, gastrointestinal stromal tumor, lymphoma, and ischemic necrosis. In 3 cases in which there was no natural passage of the capsule endoscope, lesions were identified by small bowel exploration through simple palpation by hand. Intraoperative enteroscopy was performed extracorporeally in 5 cases through a minilaparotomy window using an extended incision of a port site less than 7 cm in length. The lesions that were identified by CE preoperatively were resected successfully, via laparoscopic or laparoscopy-assisted surgery. The gastrointestinal bleeding has not recurred during the postoperative follow-up period (mean, 10.6 months).
  
  
  CONCLUSIONS
  The laparoscopic approach can be chosen for surgical management of OGB patients with active bleeding whose lesions have been identified by CE. This approach allows minimally invasive surgical treatment for ongoing OGB.
