Summary
A gunshot bullet lodged in the hip joint after a transrectal injury was successfully and spontaneously eliminated through the gastrointestinal tract. This rare case highlights effective multidisciplinary surgical collaboration.
Area of Science:
- Trauma Surgery
- Orthopaedic Surgery
- Gastrointestinal Surgery
Background:
- Gunshot wounds can result in complex foreign body injuries requiring specialized management.
- Transrectal trajectory injuries pose unique challenges due to anatomical proximity to vital structures.
Purpose of the Study:
- To report a rare case of a bullet migrating from the hip joint and being spontaneously eliminated via the gastrointestinal tract.
- To emphasize the importance of interdisciplinary communication in managing complex trauma cases.
Main Methods:
- A 25-year-old male with a gunshot wound to the buttock underwent joint management by acute care and orthopaedic surgery.
- Surgical attempts to retrieve a bullet lodged in the hip joint were unsuccessful, leading to a decision to defer removal.
- The bullet spontaneously migrated and was eliminated through the gastrointestinal tract.
Main Results:
- A bullet entered the buttock, suspected to have a transrectal course, and lodged in the hip joint.
- Despite surgical intervention, the bullet migrated further into the pelvis.
- The foreign body was ultimately expelled spontaneously via the gastrointestinal tract.
Conclusions:
- This case illustrates the rare occurrence of foreign body autoelimination.
- Effective multidisciplinary communication and collaboration are crucial for optimizing patient outcomes in complex trauma scenarios.
