Autologous peritoneal graft for venous vascular reconstruction after tumor resection in abdominal surgery: a systematic review.
Radical surgical resection (R0) is the only option to cure patients with borderline resectable or multivisceral intraabdominal malignancies involving major vessels. Autologous peritoneal flap has been described as a safe and versatile option for vascular reconstruction, but still limited experience exists regarding its use. An extensive literature review was performed to analyze results of vascular reconstruction with an autologous peritoneal graft. Fifteen reports were found for a total of 94 patients. No cases of arterial vascular reconstruction were found. Two different types of peritoneal patch have been described, backed (APFG, 30 patients) or not backed (ANFP, 64 patients) by posterior rectus sheath. A patch type of reconstruction was adopted in 70 patients (74.5%), while a tubular reconstruction in 24 (25.5%). Postoperative mortality was 5.3% (5 cases). Graft outcomes with very heterogeneous follow-ups (7 days-47 months) were available only in 85 patients (90.4%). Among them, a graft patency was documented in 80 patients (94.1%), while a stenotic graft was reported in 5 patients (5.9%). No differences in graft outcomes were observed between the patch and tubular groups (p = 0.103), nor between the ANFP and APFG groups (p = 0.625). In reported experiences, autologous peritoneal graft seems to represent a safe and versatile option for functional restoration of venous vascular anatomy after resection, especially in operations with high risk of contamination, trauma, liver transplantation and unplanned vascular resection. Unfortunately, the data available in the literature do not make it possible to draw any evidence-based conclusions on these considerations.
