Herniation through the foramen of Winslow. Report of two cases
Insights
Internal herniation through the foramen of Winslow is rare but serious. Early diagnosis and surgical intervention are crucial for successful outcomes in cases of gastrointestinal obstruction.
Area of Science:
- Gastroenterology
- Surgical Anatomy
Background:
- Internal herniation through the foramen of Winslow is a rare cause of intestinal obstruction.
- The foramen of Winslow (epiploic foramen) connects the peritoneal cavity to the lesser sac.
Observation:
- Two clinical cases of internal herniation through the foramen of Winslow are presented.
- Case 1: Herniation of the cecum and ascending colon.
- Case 2: Herniation of the ileum.
Findings:
- Preoperative clinical and radiologic findings suggested the diagnosis.
- Definitive diagnosis was established during laparotomy.
- Hernias were reduced successfully with pulse traction.
- No signs of intestinal necrosis were observed.
Implications:
- Herniation through the foramen of Winslow must be considered in the differential diagnosis of upper gastrointestinal obstruction.
- Prompt surgical management is essential for favorable outcomes.
- Understanding the anatomical variations of the foramen of Winslow is critical for surgeons.
Purpose:
Two clinical cases of internal herniation through the foramen of Winslow are presented. The first case concerns herniation of the cecum and ascending colon. In the second patient, the ileum was herniated through the foramen epiploicum.
Methods:
Preoperative assessment of clinical and radiologic findings suggested diagnosis.
Results:
Final diagnosis was only made at laparotomy. Reduction of hernia could be performed by pulse traction, and no signs of intestinal necrosis were seen.
Conclusion:
Herniation through the foramen of Winslow should be taken into account when making a differential diagnosis for upper gastrointestinal tract obstruction.
