Summary

Truncal vagotomy significantly impairs gallbladder contraction and increases resting volume, unlike selective or highly selective procedures. This surgery is linked to a higher incidence of gallstones, impacting gallbladder function.

Area of Science:

  • Gastroenterology
  • Surgical Outcomes
  • Gallbladder Physiology

Background:

  • Truncal vagotomy is associated with gallbladder volume changes and gallstone formation.
  • Selective and highly selective vagotomy do not appear to cause these adverse effects.

Purpose of the Study:

  • To investigate the impact of different vagotomy types on gallbladder function.
  • To assess gallbladder volume, contraction, and cholelithiasis incidence post-vagotomy.

Main Methods:

  • Sonographic measurement of gallbladder resting volume and contraction in 12 patients.
  • Comparison of findings with normal values and different vagotomy types (truncal, selective, highly selective).

Main Results:

  • Patients with truncal vagotomy exhibited increased gallbladder resting volume and impaired contraction.
  • Selective vagotomy patients showed normal resting volume but decreased contraction.
  • Cholelithiasis was found in 28% of truncal vagotomy patients.

Conclusions:

  • Truncal vagotomy adversely affects gallbladder motility and volume.
  • Selective vagotomy also impairs gallbladder contraction, though to a lesser extent.
  • The findings highlight the importance of surgical approach in mitigating post-vagotomy gallbladder complications.
