Use of intraoperative ultrasonography to identify a cervical foreign body. A case report.

This research article details a procedure in which real-time ultrasound technology was used to locate and guide the removal of a foreign-body abscess in the neck of a horse, which was causing an obstruction in the esophagus.

Research Background and Procedure

• The research begins by recounting the case of a horse suffering from an extraluminal esophageal obstruction caused by a foreign-body abscess in its neck. A comprehensive medical management plan had been in place for 2 months but failed to alleviate the problem.
• Due to the lack of observable signs of inflammation, such as a draining tract, it was challenging to localize the abscess. Therefore, the research team decided to use ultrasound technology to identify the containment area of the abscess.

Use of Ultrasound in Surgery

• The team used real-time ultrasound technology to guide their surgical intervention. This non-invasive tool allowed them to visualize the abscess which could not be located through traditional palpation or by searching for observable inflammatory symptoms.
• The ultrasound guided the surgical dissection and helped to minimize the risk of inadvertent damage to nearby critical anatomical structures during surgery. The process also ensured asepsis, reducing the chance of post-surgical infections.

Post-Surgical Outcome

• After the procedure, the researchers concluded that the use of intraoperative ultrasonography successfully assisted in the detection and excision of the foreign-body abscess. The signs of esophageal obstruction witnessed in the horse prior to surgery were ameliorated and have not recurred in the ensuing 15 months.
• This case provides medical practitioners with a technological tool which can be used in similar cases where visualizing and localizing abscesses are challenging. It can guide precision surgery and minimize collateral damage in clinical and veterinary settings.
