Summary
This case report describes an unusual adult umbilical hernia with vertical displacement along the abdominal wall. Surgical repair was successful, with no recurrence noted two years post-operation.
Area of Science:
- Abdominal surgery
- Hernia repair
- Gastrointestinal surgery
Background:
- Umbilical hernias are common abdominal wall defects, typically located within the umbilical region.
- Anatomical classification of hernias is crucial for accurate diagnosis and treatment planning.
Observation:
- A rare case of adult umbilical hernia with vertical dislocation of the hernial sac along the abdominal wall is presented.
- The hernial sac originated from the internal ring and extended 20 mm below it, with the umbilicus remaining depressed.
Findings:
- The patient underwent successful surgical repair with an uneventful postoperative course.
- No evidence of hernia recurrence was observed at a 2-year and 4-month follow-up, even under increased abdominal pressure.
- The cosmetic outcome of the umbilicus was deemed acceptable.
Implications:
- This case highlights an atypical presentation of umbilical hernia that deviates from typical anatomical locations.
- Accurate classification as an umbilical hernia, rather than an epigastric hernia, is supported by the sac's origin from the internal ring.
- This previously undescribed form of umbilical hernia expands the understanding of abdominal wall defect variations and their surgical management.
