Postcholecystectomy Gut Microbiome Changes and the Clinical Impact: A Systematic Review With Narrative Synthesis.
J Gastroenterol Hepatol
December 2024
Duke-NUS Medical School, Singapore.
Background: Cholecystectomy (CCE) can affect the enterohepatic circulation of bile acids and result in gut microbiome changes. This systematic review aimed to clarify the effect of CCE on gut microbiome composition and its clinical impact.
Method: A systematic search was conducted in PubMed, Web of Science, and Scopus, combining keywords such as "cholecystectomy" or "post-cholecystectomy" with "gut microbiome," "stool microbiome," or "gut dysbiosis.
Liraglutide and Colesevelam Change Serum and Fecal Bile Acid Levels in a Randomized Trial With Patients With Bile Acid Diarrhea.
Clin Transl Gastroenterol
November 2024
Center for Clinical Metabolic Research, Copenhagen University Hospital-Herlev and Gentofte, Hellerup, Denmark.
Introduction: Both liraglutide and colesevelam improve bile acid diarrhea symptoms. Colesevelam binds excess amounts of diarrhea-causing bile acids in the colon, whereas the mode of action for liraglutide remains elusive. In this article, we examined the impact of colesevelam and liraglutide treatment on the concentrations of bile acids in serum and feces and the fecal microbiota composition to better understand the 2 drugs' modes of action.

Medical Laboratory Technology, College of Nursing and Health Sciences, Jazan University, Jazan, SAU.
Article Synopsis
- Traumatic neuromas are uncommon in the digestive system, with the biliary tree being the typical area affected post-cholecystectomy or liver transplantation.
- This report details a rare case of a rectal neuroma in a 48-year-old man who had familial adenomatous polyposis and prior surgery for colon cancer.
- The lesion was initially suspected to be recurrent cancer based on clinical assessments but was later identified as a traumatic neuroma after surgical removal.
Alteration of ascending colon mucosal microbiota in patients after cholecystectomy.
World J Gastrointest Surg
August 2024
Department of Gastroenterology, Jiading Branch of Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 201803, China.
Article Synopsis
- Cholecystectomy, a surgery for treating gallstones, may lead to an increased risk of colorectal cancer (CRC) in patients, possibly linked to changes in gut microbiota.
- A study involving 30 post-cholecystectomy patients and 28 healthy controls analyzed mucosal biopsy samples using advanced sequencing techniques to examine the bacterial communities.
- The findings revealed that older post-cholecystectomy patients had different gut microbiota compositions and higher levels of certain beneficial bacteria, suggesting potential implications for CRC treatment and gastrointestinal issues following surgery.
An unusual case of gallstone ileus 35 years post-cholecystectomy masked by an incisional hernia.

Gallstone ileus is an uncommon cause of mechanical bowel obstruction in patients with cholecystitis and gallstones who develop a fistula over time. In the post-cholecystectomy patient, the presence of gallstone ileus is extremely rare; these patients have different pathophysiological pathways, such as a spilled gallstone that subsequently erodes into the bowel, subtotal cholecystectomies, and diverticulae that can hold a gallstone for hidden several years. In these patients, the clinical presentations are unique because of their rarity and because the gallbladder had been previously removed.
