RESUMO

BACKGROUND: Ingestion of foreign bodies such as fish bone or chicken bone is relatively common in adults; however, resultant transmural migration is extremely rare. METHODS: We present a case of a 79-year-old woman with chronic low-grade abdominal pain, worsening over the last 4 days. Computed tomography revealed segmental small bowel wall thickening with chronic inflammation suggestive of Crohn's ileitis and oral steroids were commenced; only later, ingestion of a foreign body was suspected. RESULTS AND CONCLUSION: At diagnostic laparoscopy, a linear foreign body resembling a wooden splinter was identified. It had partly migrated through the chronically inflamed bowel wall without causing perforation or abdominal contamination. It was removed laparoscopically without an enterotomy or bowel resection. Microscopy revealed non-viable bone, likely fish or chicken bone. The patient made an uneventful recovery and was discharged 3 days later. Herein we emphasise on the differential diagnosis and presentation of chronically ingested foreign bodies, as well as the feature of chronic ileitis with uncomplicated transmural migration of the ingested foreign body that was treated laparoscopically without an enterotomy.

RESUMO

BACKGROUND: Retrieved metal-on-metal acetabular cups are valuable resources in investigating the wear behaviour of failed hip implants, but adequate methods to do so are lacking. To further contribute to addressing this issue, we developed a method to detect the in vivo location of the primary wear scar of an explanted cup. METHODS: We proposed a new method in which thirteen patients with failed metal hip resurfacings were recruited, and their acetabular components retrieved. A 3D wear map was generated and the precise location of the primary wear scar in each cup was identified using a coordinate measuring machine. This wear scar location was noted in relation to the features on the acetabular cup. Having identified the location of the wear scar, this 3D positional map was co-registered to the implant on the patient's pelvic 3D CT scan. RESULTS: Using our proposed technique, we were able to demonstrate that the in vivo position of the primary wear scar in explanted metal acetabular cups can be variable. CONCLUSIONS: This method has utilised existing techniques to better understand the three-dimensional properties of wear behaviour, and may be a method which can be used in further studies to investigate variables that affect the position of the primary wear scar.
