[Gallbladder motor function studied by modified infusion cholescintigraphy method after gastric and duodenal surgery]

Area of Science:

• Gastroenterology
• Nuclear Medicine
• Surgical Outcomes

Background:

• Gallbladder (GB) motility disorders post-gastric surgery lack reliable diagnostic methods.
• Assessing GB motility is crucial for understanding post-surgical complications.

Purpose of the Study:

• To introduce, modify, and establish infusion cholescintigraphy for clinical GB motility assessment.
• To evaluate GB motility disorders in patients after various gastric surgeries.

Main Methods:

• Infusion cholescintigraphy was performed on patient groups: gastric resection (RVBI, RVBII), total gastrectomy, and gastroplasty.
• Data analyzed motility disorders related to bilateral truncal vagotomy and food transit through the duodenum.
• Motility was assessed at different time points post-operation.

Main Results:

• Patients without truncal vagotomy (RVBI, RVBII) showed minor motility disorders compared to those with vagotomy.
• Total gastrectomy patients exhibited higher motility disorders at 6 months, with recovery by 9-12 months.
• Preserved duodenal transit (RVBI, gastroplasty) correlated with less severe motility issues than absent transit (RVBII, total gastrectomy).

Conclusions:

• Infusion cholescintigraphy provides a reliable method for assessing gallbladder motility post-gastric surgery.
• Truncal vagotomy and lack of duodenal food transit are significant factors in GB motility disorders.
• GB motility disorders are time-dependent and can recover post-surgery.
