A 60-year-old Italian man arrived at our department with abdominal distension and acute periumbilical pain. Over the two preceding years, our patient had undergone an extensive negative workup performed for recurrent episodes of abdominal pain and diarrhea, including comprehensive blood and stool studies, CT, abdominal ultrasound, esophogastroduodenoscopy, colonoscopy, barium enema and small bowel follow-through. Twenty-four hours prior to his arrival, our patient had undergone CE, the results of which were still pending.\nOn admission, our patient was febrile. His physical examination revealed a distended abdomen with increased bowel sounds and marked tenderness in the right lower quadrant. Laboratory tests showed a white blood cell count of 16,300 cells/mL (normal: 4,500 to 10,500 cells/mL) and hemoglobin of 10.7g/dL (normal: 12g/dL to 16g/dL).\nA CT scan of his abdomen was performed and showed the presence of the capsule endoscope located in his distal ileum and a stricture along with extensive small bowel distension, a thickened bowel wall and loculated free air (Figure ). Our patient underwent an urgent laparotomy. During the surgical exploration, an ileum perforation was noted proximal to an inflammatory-like stricture located in his distal ileum (Figure ), which led to the resection of the inflamed segment with ileocolic anastomosis. Histology confirmed the diagnosis of Crohn’s disease. His postsurgical course was uneventful, and our patient was discharged 10 days later and treated subsequently with medications for Crohn’s disease with good results.
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.
