Pancreatic fistula after pancreatic head resection; incidence, significance and management

Abstract

Background/aims: Anastomotic leak at the pancreatojejunostomy remains a common and dreaded complication after pancreaticoduodenectomy. Our aim was to determine the incidence, presentation, methods of management, and preoperative and postoperative factors that influence the clinical outcome.

Methodology: We reviewed our collective experience with 70 consecutive patients from 1985 to 2000 for a variety of pathologic indications. Clinical, biochemical, intraoperative and postoperative factors were reviewed in an attempt to determine prognostic factors.

Results: Nine patients (12%) developed a pancreatic anastomotic leak as determined by increased amylase in drainage fluid (70%), were clinically insignificant and were managed by simple maintenance of intraoperatively placed drains. Although octreotide was used therapeutically in 4 patients (44%), significant, objective response was noted in all patients. Of the clinical, biochemical, intraoperative and postoperative factors reviewed to determine prognostic factors, a large amount of postoperative pancreatic juice output (P = 0.02) was a significant risk factor for pancreatic fistula formation.

Conclusions: We conclude that most anastomotic leak at pancreaticoenterostomy after pancreaticoduodenectomy can be managed conservatively. Use of octreotide to aid in closure of the pancreatic leak was satisfactory.
