Effect of octreotide acetate on pancreatic exocrine function

Area of Science:

• Gastroenterology
• Endocrinology
• Surgical Research

Background:

• Somatostatin and its analogs are known to inhibit pancreatic endocrine and exocrine functions.
• The precise mechanism by which somatostatin analogs affect pancreatic fluid dynamics and composition is not fully understood.

Purpose of the Study:

• To investigate the effect of octreotide acetate on pancreatic fluid output and composition.
• To determine if octreotide acetate alters pancreatic fluid chloride, sodium, potassium, amylase, lipase, and bicarbonate levels.
• To explore the potential therapeutic role of somatostatin analogs in managing pancreatic fistulas.

Main Methods:

• Pancreatic fluid was collected from six patients with pancreatic fistulas or drains post-resection.
• Fluid volume and electrolyte, enzyme, and bicarbonate concentrations were measured before and after octreotide acetate administration.
• Statistical analysis was performed to assess the significance of observed changes.

Main Results:

• Octreotide acetate reduced pancreatic fluid output by 75% (p<0.05).
• Chloride concentration increased by 21% (p<0.05), bicarbonate decreased by 45% (p<0.05), and potassium increased by 14% (p<0.05).
• Total amylase and lipase production decreased, though not significantly.

Conclusions:

• Octreotide acetate effectively decreases pancreatic fluid output and modifies its electrolyte and bicarbonate content.
• Somatostatin analogs show potential utility in treating existing pancreatic fistulas.
• These agents may also serve as a prophylactic measure against postoperative pancreatic fistula formation.
