Plasma gastrin and secretin changes after esophagectomy
The American Journal of Gastroenterology
|October 1, 1986
Summary
Esophageal cancer surgery (esophagogastrectomy) temporarily increased gastrin levels in patients. G cell hyperplasia was observed in those with high gastrin, suggesting a link between G cells and post-surgical gastrin changes.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endocrinology
Background:
- Esophageal cancer often requires esophagogastrectomy, a major surgery impacting digestive function.
- Post-surgical hormonal changes, particularly in gastrin, are not fully understood.
- G cells play a crucial role in regulating gastrin secretion.
Purpose of the Study:
- To investigate plasma gastrin and secretin levels after esophagogastrectomy in esophageal cancer patients.
- To explore the correlation between G cell population and plasma gastrin levels.
- To understand the impact of surgery on gastrointestinal hormone regulation.
Main Methods:
- Plasma gastrin and secretin levels were measured in 14 patients undergoing esophagogastrectomy.
- Six patients received hydrochloric acid to assess secretin secretion.
- G cell population in the stomach was analyzed using enzyme antibody staining.
Main Results:
- Hypergastrinemia (elevated plasma gastrin) was observed one month post-surgery, normalizing by three months.
- Plasma secretin levels showed a downward trend post-surgery, but without statistical significance.
- G cell hyperplasia was identified in hypergastrinemic patients without pyloric antral atrophy.
Conclusions:
- Esophagogastrectomy leads to transient hypergastrinemia.
- G cell hyperplasia is associated with elevated post-surgical gastrin levels.
- Further research is needed to clarify the role of secretin in this context.
