Background: Primary thoracoabdominal hernias involve the triad of an intercostal hernia, abdominal wall hernia, and diaphragmatic hernia. We report a case series of this rare entity and describe the evolution and outcomes.
Methods: We completed a retrospective analysis of thoracoabdominal hernia repairs performed January 2010-April 2019 at Prisma Health-Upstate and Carolinas Medical Center. This includes all patients with spontaneous defects, excluding incisional hernias or those resulting from external trauma.
Results: Of 16 patients with thoracoabdominal hernias, 15 patients developed hernias after forceful coughing and one patient developed a hernia after strenuous physical activity. Seven patients required at least one additional intervention; two for recurrence; two for recurrence of original intercostal repairs done elsewhere; two for wound complications; and one had a missed abdominal wall component.
Conclusions: Primary thoracoabdominal hernias require a high index of suspicion. Durable repair involves complex reconstruction of the thoracoabdominal wall including the diaphragm, intercostal space, rib fracture fixation, and mesh reinforcement of the abdominal wall with permanent fixation constructs.
Keywords: Rib fracture and hernia; Spontaneous diaphragm hernia; Spontaneous intercostal hernia; Spontaneous thoracoabdominal hernia; Thoracoabdominal hernia.
