Cholecystitis following the initiation of glucagon-like peptide-2 analogue for short bowel syndrome: A case report.

Patients with short bowel syndrome (SBS) have a risk for cholelithiasis and cholecystitis, particularly those who have received long-term parenteral nutrition (PN). Teduglutide (Revestive), a glucagon-like peptide-2 (GLP-2) analogue, is the first effective therapy approved for treating patients with SBS via self-subcutaneous injection. It also pharmacologically inhibits gallbladder contraction, which may increase the risks for cholelithiasis and cholecystitis. Here, we report a case of cholecystitis occurring after the introduction of a GLP-2 analogue in a patient with SBS and cholelithiasis. A 16-year-old girl, with a residual intestinal anatomy of 5 cm jejunum and left colon, was referred to our hospital for further treatment of SBS. She underwent jejunocolic anastomosis 2 months later. After that, she received PN for 2.5 years. Teduglutide treatment was initiated to reduce PN dependence. Several asymptomatic gallbladder stones were found during a routine ultrasound examination before drug initiation. On day 31 of teduglutide treatment, right subcostal pain with fever occurred, and the patient was diagnosed with acute cholecystitis. GLP-2 analogue treatment was temporarily discontinued. The patient underwent gallbladder drainage followed by cholecystectomy 3 weeks later. Histopathological findings illustrated mucosal hyperplasia of the gallbladder. Her postoperative course was uneventful, and teduglutide was restarted 2 weeks postoperatively. GLP-2 analogues promote gallbladder refilling and epithelial hyperplasia, which may be a risk factor for cholecystitis in patients with cholelithiasis, as observed in our patient. Based on our experience, patients with SBS and established asymptomatic cholelithiasis may be considered for prophylactic cholecystectomy before the administration of GLP-2 analogues.
