Pancreatic exocrine function after truncal and highly selective vagotomy

Area of Science:

• Gastroenterology
• Endocrinology
• Surgical Research

Background:

• Vagotomy, a surgical procedure involving the vagus nerve, is used to reduce stomach acid production.
• Potential complications include effects on pancreatic function and glucose metabolism.
• Different types of vagotomy, such as truncal and highly selective, may have varying impacts.

Purpose of the Study:

• To compare the postoperative effects of truncal vagotomy (TV) and highly selective vagotomy (HSV) on pancreatic exocrine function and glucose levels.
• To assess the incidence of exocrine pancreatic insufficiency following both surgical procedures.
• To determine if one vagotomy type is preferable for patients with or at risk for diabetes mellitus.

Main Methods:

• Plasma glucose, serum pancreatic amylase, and immunoreactive trypsin concentrations were measured.
• Measurements were taken from single blood samples post-surgery.
• The study included 13 patients who underwent TV and 14 patients who underwent HSV.

Main Results:

• An increased incidence of exocrine pancreatic insufficiency was observed postoperatively, irrespective of the vagotomy type.
• Plasma glucose concentrations were significantly higher following truncal vagotomy compared to highly selective vagotomy.
• Serum pancreatic amylase and immunoreactive trypsin levels indicated impaired exocrine function in both groups.

Conclusions:

• Both truncal vagotomy and highly selective vagotomy are associated with postoperative exocrine pancreatic insufficiency.
• Highly selective vagotomy appears to be a more favorable option for patients with or at risk of diabetes mellitus due to better glucose control.
• Further research is warranted to fully elucidate the long-term effects on pancreatic function.
