Short description of contents:
Background: Indocyanine green fluorescence imaging can be used for intraoperative assessment of
pancreatic stump perfusion with the aim to guide strategies to prevent postoperative pancreatic fistula in pancreatic surgery. The impact of indocyanine green in this setting is unknown since a systematic
review is lacking. This review aimed to assess the relationship between indocyanine green fluorescence imaging of pancreatic stump perfusion and the risk of clinically relevant postoperative pancreatic fistula after pancreatic surgery.
Methods: A systematic literature search and meta-analysis were conducted, including studies published
up to June 2025 that reported postoperative pancreatic fistula rate after pancreatic resection in relation
to intraoperative pancreatic stump perfusion assessed by intraoperative indocyanine green fluorescence imaging. Hypoperfusion was defined as a heterogeneous or completely absent signal. Primary outcome
was postoperative pancreatic fistula of which only grade B/C were included. Secondary outcome was
postpancreatectomy acute pancreatitis.
Results: All 3 studies included analyzed patients who underwent pancreatoduodenectomy, comprising a
total of 100 patients, with 18 (18%) presenting pancreatic stump hypoperfusion. No studies analyzing
left pancreatectomy were identified, whereas only 1 paper analyzed the association between pancreatic
hypoperfusion and postpancreatectomy acute pancreatitis. In that study, no patients developed postpancreatectomy
acute pancreatitis after revision of the transection line initially found to be hypoperfused.
The overall rate of postoperative pancreatic fistula was 13%. After robotic
pancreatoduodenectomy (n = 27), stump hypoperfusion was associated with postoperative pancreatic
fistula (67% vs 17%; P = .026), compared to the normally perfused group. No significant association of
hypoperfusion and postoperative pancreatic fistula was observed after open pancreatoduodenectomy
(n = 73). Meta-analysis confirmed the association of stump hypoperfusion with postoperative
pancreatic fistula (odds ratio, 8.83; 95% confidence interval, 2.21—35.23; P = .005). Conclusion:
A hypoperfused pancreatic stump, assessed intraoperatively using indocyanine green fluorescencfluorescence imaging, appears to be associated with postoperative pancreatic after
creatoduodenectomy. Further research is needed to these results in left pancreatectomy and develop a standardized indocyanine green protocol for pancreatic surgery
