Use of Nonvascularized Abdominal Rectus Fascia After Liver, Small Bowel, and Multiorgan Transplantation: Long-Term Follow-up of a Single-Center Series.

BACKGROUND

The abdominal wall may be severely compromised in the vast majority of intestinal and multiorgan transplant candidates, and sometimes as a consequence of complex liver transplantation. Multiple options have been described to overcome this problem, varying from component separation to the extreme need of performing an abdominal wall transplantation. The aim of the present paper is to report the largest and longest-term results of patients that received an abdominal rectus fascia (ARF) after liver, intestinal, or multiorgan transplantation at a single transplant center.

METHODS

This is a retrospective report of a prospectively collected dataset of all the patients that received ARF during liver, isolated intestine, combined, or multiorgan transplantation at Fundación Favaloro from May 2006 to June 2016.

RESULTS

A total of 19 out of 528 patients (3.5%) that underwent abdominal organ transplant received an ARF graft: 17 patients after receiving an intestine-containing graft, and 2 after liver retransplantations. Three patients required changing the ARF, 2 with a synthetic mesh and 1 with another ARF. Five patients required late reoperations: A relaparotomy was performed by transecting the ARF without encountering adhesions on the inner ARF surface. None of the 2 patients who received liver retransplantations and ARF developed acute or chronic ventral defects.

CONCLUSIONS

The use of ARF is a simple and reliable surgical option to close abdominal wall defects during transplantation, the fascia adequately incorporates to the abdominal wall, allowing it to be transected and resutured in the long term and preserving the integrity of the peritoneal layer.
