Grynfeltt Hernia: A Rare Case With Serious Complications.

Abstract

Grynfeltt-Lesshaft hernia is a rare type of abdominal hernia. The diagnosis remains challenging, particularly in urgent clinical scenarios. The choice of a surgical technique remains controversial, as each approach carries specific advantages and limitations. We present a case of an incarcerated lumbar hernia through the superior lumbar triangle with a large focal defect identified on diagnostic imaging, which led to an early recurrence and a sequence of complications, including bowel perforation, colonic necrosis, and abscess formation with fistulation. This case highlights the complexity of surgical decision-making in emergency presentations and the importance of selecting the appropriate method for primary repair of rare abdominal defects.
