Abstract
Background: Richter’s hernia is an uncommon but potentially life-threatening type of abdominal wall hernia characterized by incarceration of only a portion of the intestinal circumference, usually the antimesenteric border. Unlike conventional incarcerated hernias, it may progress to intestinal ischemia and necrosis without causing complete bowel obstruction, frequently delaying diagnosis and increasing the risk of serious complications.
Aim: This review aims to provide a comprehensive overview of Richter’s hernia, emphasizing its etiology, epidemiology, pathophysiology, clinical presentation, diagnostic evaluation, treatment, complications, prognosis, and patient education.
Methods: A narrative review approach was used to synthesize available literature addressing the anatomical mechanisms, clinical characteristics, diagnostic challenges, and contemporary management of Richter’s hernia. Particular attention was given to emergency recognition, assessment of bowel viability, surgical approaches, postoperative care, and recurrence prevention.
Results: Richter’s hernia most commonly affects the small intestine and is associated with femoral and inguinal hernias, incisional defects, and previous minimally invasive surgical procedures. Its distinctive pathophysiology allows intestinal contents to pass despite progressive vascular compromise of the entrapped bowel wall. Clinical manifestations range from localized pain and tenderness to intestinal necrosis, perforation, peritonitis, and sepsis. Ultrasonography and computed tomography support diagnosis, although negative imaging findings do not exclude the condition. Management requires prompt surgical assessment, appropriate resuscitation, antimicrobial therapy when indicated, and timely operative intervention. Bowel resection may be necessary when irreversible ischemia or necrosis is identified.
Conclusion: Early recognition, individualized surgical management, and appropriate postoperative surveillance are essential to minimize complications and improve outcomes.
