    Postoperative small intestine resorption, measured by the D-xylose test, initially decreased after cholecystectomy but normalized by day 8. Intestinal myoelectrical activity recovered faster than D-xylose absorption.

    Area of Science:

    • Gastroenterology
    • Surgical Recovery
    • Physiology

    Context:

    • Cholecystectomy, the surgical removal of the gallbladder, can impact small intestine function.
    • Postoperative recovery of gastrointestinal function is crucial for patient well-being.
    • Understanding changes in nutrient absorption after surgery is vital for clinical management.

    Purpose:

    • To evaluate the impact of cholecystectomy on small intestine D-xylose absorption.
    • To assess the timeline for the normalization of enteral absorption post-surgery.
    • To compare the recovery rates of small intestine myoelectrical activity and D-xylose resorption.

    Summary:

    • A modified D-xylose resorption test was administered to 14 patients on days 2, 4, 6, and 8 after cholecystectomy.

  • Enteral D-xylose resorption velocity and dimension were reduced in the immediate postoperative period, normalizing by day 8.
  • Small intestine myoelectrical activity normalized sooner than D-xylose resorption, with a correlation observed between gastric motor activity and xylose resorption.

    • Impact:

    • This study quantifies the temporary impairment of small intestine absorption following cholecystectomy.
    • Findings suggest that while motor function recovers rapidly, absorptive capacity takes longer to return to baseline.
    • Further research is needed to fully elucidate factors like electrolyte balance and microcirculation affecting postoperative intestinal absorption.
