Left paraduodenal hernia, a diagnostic challenge.

Area of Science:

• Gastroenterology
• Surgical Innovation
• Abdominal Surgery

Background:

• Left paraduodenal hernias are rare internal hernias causing small bowel obstruction.
• Diagnosis can be challenging due to non-specific symptoms and unremarkable imaging.
• Prompt identification is crucial to prevent complications like strangulation and ischemia.

Observation:

• A 21-year-old male presented with chronic, intermittent abdominal pain.
• Diagnostic laparoscopy revealed a left paraduodenal hernia.
• The hernia was surgically reduced.

Findings:

• The surgical strategy involved intentionally leaving the hernial defect (fossa of Landzert) widely open.
• This approach was supported by anatomical and pathophysiological rationale.
• The patient remained symptom-free at a 21-month follow-up.

Implications:

• Highlights the need for a high index of suspicion for diagnosing left paraduodenal hernias.
• Proposes an alternative surgical technique for managing this rare internal hernia.
• Demonstrates the potential efficacy of leaving the hernial defect open in select cases.
