Abstract
Background
The small bowel has been considered the “black box” of gastroenterology. Identifying the exact site of small bowel hemorrhage is often difficult, thus complicating surgical treatment. We report two cases of small bowel bleeding lesions that were successfully managed by intraoperative real-time capsule endoscopy and minimally invasive surgery.
Methods
We developed a double-lumen tube similar to, but thinner and longer than, the Miller–Abbott tube. We insert the tube nasally, 3 or 4 days preoperatively, such that its balloon tip reaches the anus by the operative day. During surgery, the endoscopic capsule is connected to the balloon tip of the tube that protrudes from the anus. An assistant pulls on the nasal end of the tube, bringing the balloon tip and capsule back into the bowel. Capsule endoscopic images are displayed in a real-time video format.
Results
We employed this procedure in two patients with repeated melena. Various examinations including gastroendoscopy and total colonoscopy showed bleeding confined to the small bowel, but the exact lesion site was unknown. Minimally invasive surgery was successfully performed in both patients: open minilaparotomy in one and laparoscopy in the other. The small bowel and capsule endoscope were easily controlled during minilaparotomy, and real-time capsule endoscopic images clearly identified the bleeding lesion. Control of the small bowel was more difficult in the laparoscopic case; however, real-time capsule endoscopic images identified a small tumor that was successfully resected.
Conclusions
Intraoperative capsule endoscopy combined with the tube provides surgeons real-time images indicating the exact site of lesions. The tube also helps surgeons control the position of the capsule endoscope and enables suction of intraluminal fluid or inflation of the lumen to allow clearer views during the operation. We conclude that combined use of capsule endoscopy and the tube facilitates management of bleeding lesions in the small bowel.
