Reconstruction of the abdominal wall in patients with prune-belly syndrome (PBS) following previous intra-abdominal procedures is a challenging problem with a high incidence of revision due to persistent bulging or herniation. The abdominal wall flaccidity not only produces a severe psychological and aesthetic discomfort for the patient but often determines functional disabilities, including inability to cough properly, impaired bowel and bladder function, and delay in posture and balance.
The authors describe three cases of reconstruction of abdominal wall using a modified double-breasted abdominoplasty fascial plication with additional acellular dermal matrix interposition and review the literature for innovations in the use of abdominal repair for reconstruction of these difficult cases.
Three children with PBS at a mean age of 7.3 years achieved successful reconstruction of the abdominal wall, using the modified double-breasted abdominoplasty fascial plication with acellular dermal matrix interposition. Patients underwent previous procedures, including orchiopexy in two patients and bilateral nephrectomy in one patient. No postoperative complications have been found, apart from superficial skin dehiscence along the abdominal incision treated conservatively in one child. At mean follow-up of 42 months (range 28-56 months), no patient presented incisional hernia, persistent or recurrent fascial laxity with abdominal bulging. All patients achieved significant aesthetic and functional improvements, including children's ability to cough, spontaneous gain of abdominal tonus, balance, and ambulation.
Modification of the original vertical, two-layer plications of the deficient abdominal interposing biological mesh has the purpose of improving strength, aesthetics, and function of the abdominal wall in pediatric patients with PBS.
