A Rare Type of Primary Internal Hernia Causing Small Intestinal Obstruction

Area of Science:

• Gastroenterology
• Surgical Pathology
• Abdominal Imaging

Background:

• Primary internal hernias are uncommon causes of small intestinal obstruction in adults.
• Clinical symptoms are often nonspecific, and imaging interpretation can be challenging, delaying diagnosis.
• Untreated internal hernias carry significant risks of morbidity and mortality.

Purpose of the Study:

• To report an extremely rare case of primary internal hernia presenting as acute intestinal obstruction.
• To discuss the diagnostic challenges and surgical management of this rare condition.

Main Methods:

• Case report of a 45-year-old male with acute intestinal obstruction.
• Diagnosis was confirmed intraoperatively during exploratory laparotomy.
• Surgical intervention involved intestinal reduction and hernial defect repair.

Main Results:

• A rare variant of internal hernia involving a loop of ileum entering the retroperitoneum via the left paracolic gutter was identified.
• The patient underwent successful surgical repair.
• This case represents an unusual anatomical presentation of a retroperitoneal hernia.

Conclusions:

• Primary internal hernias, though rare, must be considered in the differential diagnosis of small intestinal obstruction.
• Prompt surgical intervention is crucial for favorable outcomes.
• This case underscores the diversity of internal hernia presentations, particularly retroperitoneal variants.
