Falciform ligament wrap for prevention of gastroduodenal artery bleed after pancreatoduodenectomy

Abstract

BackgroundThe present study aims to assess the effectiveness and current evidence of a pedicled falciform ligament wrap around the gastroduodenal artery stump for prevention of erosion hemorrhage after pancreatoduodenectomy (PD). MethodsRetrospective data were pooled for meta-analysis. At the own center, patients who underwent PD between 2012 and 2015 were retrospectively analyzed based on the intraoperative performance of the wrap. A systematic literature review and meta-analysis was performed that combined the published and the obtained original data. The following databases were searched: Medline, Embase, Web of Science, and the Cochrane Library. ResultsAt the own center, a falciform ligament wrap was performed in 39 of 196 PDs (20%). The wrap group contained more ampullary neoplasms, but the pancreatic fistula rate was not significantly different from the nonwrap group (28% versus 32%). In median, erosion hemorrhage occurred after 21.5 d, and it was lethal in 39% of the patients. Its incidence was not significantly lower in the wrap group (incidence: 7.7% versus 9.6% in the nonwrap group). The systematic literature search yielded four retrospective studies with a high risk of bias; only one study was controlled. When the five data sets of published and own cases with a falciform ligament wrap were pooled, the incidence of erosion hemorrhage was 5 of 533 cases (0.9%) compared with 24 of 297 cases (8.1%) without the wrap. ConclusionsThe reported incidence of erosion hemorrhage after the falciform ligament wrap is low, but there are still insufficient controlled data to support its general use.
