Effect of cholecystectomy on bowel function: a prospective, controlled study.

Area of Science:

• Gastroenterology
• Surgical Outcomes
• Bowel Function Studies

Background:

• Existing post-cholecystectomy diarrhea estimates rely on limited data.
• Previous studies often overlook functional bowel disorders and lifestyle changes.

Purpose of the Study:

• To prospectively assess bowel function and symptom changes after laparoscopic cholecystectomy.
• To differentiate surgical effects from non-specific laparoscopic procedure impacts.

Main Methods:

• 106 adult patients undergoing laparoscopic cholecystectomy and 37 women undergoing laparoscopic sterilization were studied.
• Pre- and post-surgery questionnaires and defecation records (stool form, frequency) were collected over 2-6 months.

Main Results:

• Cholecystectomy patients perceived less constipation and slightly more frequent stools, but objective records showed no consistent changes in bowel function or stool form.
• Diarrhea was reported rarely post-surgery, and when present, it was mild and not clearly new.
• Dietary fiber intake changes did not correlate with bowel function, but discontinuing constipating medications did in some patients.

Conclusions:

• Cholecystectomy may lead to a subjective perception of improved bowel regularity in women, but objective data indicates minimal impact on bowel function.
• Clinically significant diarrhea is an uncommon outcome following cholecystectomy and is typically mild.
