A 58-year-old Caucasian male with a reported 30 year history of CD presented to his gastroenterologist with intermittent diarrhea controlled by bismuth subsalicylate (Kaopectate). He denied any recent flares or pharmacologic management. A colonoscopy was negative for classical findings of CD and the patient next underwent WCE to document possible disease in the SB. On the evening of the procedure the patient reported poorly localized abdominal pain and copious non-bilious/non-bloody emesis. Over the next 48 hours he experienced progressive abdominal distention and presented to the Emergency Department. He denied the chronic use of NSAIDs or a history of prior abdominal operations.\nOn admission the patient was febrile, tachycardic and tachypneic. He also presented with severe hypotension requiring vasopressors. His physical exam was positive for icteric sclera, a distended abdomen with increased bowel sounds, and marked tenderness in the right lower quadrant. He had a WBC of 13.9 × 109/L (4.5-11.0 × 109/L) and platelet count of 79 × 109/L (150-450 × 109/L). His creatinine was 203.3 umol/L (58-111 umol/L) and total bilirubin was 171 umol/L (3-22 umol/L). A CT scan of the abdomen/pelvis revealed a capsule endoscope located near the terminal ileum along with diffusely thickened bowel wall, fat stranding in the right lower quadrant, hemorrhagic ascities and loculated free air (), reported as ischemic enteritis and SB perforation.\nAfter adequate resuscitation the patient was taken to the operating room where an ileocecectomy was performed, including removal of 160 cm of SB. The capsule endoscope found just proximal to the stricture. Given the patient’s hemodynamic instability the abdomen was initially closed with a 2 mm GORE-TEX (WL Gore & Associates Inc., Flagstaff, AZ) patch and loose suture. He required 12 subsequent operations for various complications and was discharged after 1 month with an ileostomy and colostomy. Pathology of the resected specimen showed an ileal stricture 15 cm proximal to the ileocecal valve, with associated necrotizing ileitis. A perforation was noted just proximal to the stricture where the capsule endoscope was found.
A 50-year-old man with gradually worsening anemia and suspected small bowel bleeding was referred to our hospital to undergo CE because esophagogastroduodenoscopy and total colonoscopy did not reveal the source of the gastrointestinal bleeding. His oral medications included several psychoactive drugs and iron preparations but not nonsteroidal anti-inflammatory drugs. He had no history of abdominal surgery. We did not perform patency examination before CE because we assessed low possibility of severe stenosis and inflammatory bowel disease based upon his clinical history and abdominal X-ray examination. CE (PillCam SB2 system, Given Imaging, Yokneam, Israel) demonstrated several ulcers at the small intestine, but the capsule did not reach the cecum during the recording time (stomach transit time: 220 minutes). These results were sent to his primary care doctor. Five months after the CE examination, he was referred again for the recurrence of anemia. Abdominal X-ray examination revealed that the capsule was retained at the pelvic cavity (). Follow-up abdominal X-ray examination after 7 days demonstrated that the capsule remained in exactly the same part but was rotatable (). Computed tomography (CT) showed that the capsule seemed to be floating in the small intestinal lumen with dilatation and fluid collection proximal to the capsule (). Additionally, the CT coronal view indicated findings suspicious for stenosis distal to the capsule (). The patient had had regular bowel movements and no abdominal complaints for the past 5 months. He could not confirm that the capsule was egested because he failed to monitor his stools. After proper informed consent was obtained, we retrieved the capsule by laparoscopy-assisted surgery. The patient declined endoscopic approach and treatments. Laparoscopic instruments were placed through 3 trocars. The CE was laparoscopically detected approximately 50 cm from the end of the ileum. After fluoroscopic confirmation, the part of the ileum with the capsule was moved outside the abdominal cavity, and we made the following observations around the area of retention: the fat-wrapping sign and a caliber change were observed distal to the capsule, with reddened serosa proximal to the capsule. The capsule could not pass through this stricture (). The small intestine was extensively evaluated, and no other abnormalities were found. We resected approximately 30 cm of ileum and performed a functional end-to-end anastomosis. An ulcer scar with stricture was macroscopically observed, and a wide ulcer was observed at the proximal side of the lesion (). On histopathological examination, the lesions were determined to be a nonspecific ulcer (Ul III) with fibrosis, formation of lymphoid follicles, and infiltration of monocytes and neutrophils to the subserosa, without evidence of malignancy, inflammatory bowel disease, or tuberculosis (). The patient's postoperative course was uneventful, and he was discharged on the postoperative day 8. There was no evidence of progression of anemia at a follow-up visit conducted 7 months after surgery.
