Abstract
BACKGROUND
Post-operative pancreatic fistula (POPF) is the primary cause of morbidity following pancreaticoduodenectomy. Rates of POPF have remained high despite well known risk factors. The theory that hypoperfusion of the pancreatic stump leads to anastomotic failure has recently gained interest.
AIM
To define the published literature with regards to intraoperative pancreas perfusion assessment and its correlation with POPF.
METHODS
A systematic search of available literature was performed in November 2022. Data extracted included study characteristics, method of assessment of pancreas stump perfusion, POPF and other post-pancreatic surgery specific complications.
RESULTS
Five eligible studies comprised two prospective non-randomised studies and three case reports, total 156 patients. Four studies used indocyanine green fluorescence angiography to assess the pancreatic stump, with the remaining study assessing pancreas perfusion by visual inspection of arterial bleeding of the pancreatic stump. There was significant heterogeneity in the definition of POPF. Studies had a combined POPF rate of 12%; intraoperative perfusion assessment revealed hypoperfusion was present in 39% of patients who developed POPF. The rate of POPF was 11% in patients with no evidence of hypoperfusion and 13% in those with evidence of hypoperfusion, suggesting that not all hypoperfusion gives rise to POPF and further analysis is required to analyse if there is a clinically relevant cut off. Significant variance in practice was seen in the pancreatic stump management once hypoperfusion was identified.
CONCLUSION
The current published evidence around pancreas perfusion during pancreaticoduodenectomy is of poor quality. It does not support a causative link between hypoperfusion and POPF. Further well-designed prospective studies are required to investigate this.
Core Tip: The pathology of post-op pancreatic fistula remains to be elucidated, however, hypoperfusion of the pancreatic remanent is a suggested mechanism leading to post-operative pancreatitis and failure of the pancreatic jejunal anastomosis. Indocyanine green assessment of the pancreatic remanent is a safe way to visualise perfusion of the stump prior to anastomosis. Whether it can predict post-operative pancreatic fistula requires further studies.
