Laparoscopic-Assisted Enterolithotomy for Recurrent Gallstone Ileus: A Case Report

Gallstone ileus is the mechanical obstruction of the bowel due to gallstone impaction. It forms when a fistula is created between the gallbladder and the gastrointestinal tract, which can result in small bowel obstruction. Its surgical management ranges from enterolithotomy, cholecystectomy, and fistula closure performed together (one-stage) or performed separately (two-stage), while some patients undergo simple enterolithotomy. Emergency surgery with open enterolithotomy, with or without biliary tract surgery, has been replaced by laparoscopic-assisted enterolithotomy as a safer and more rapid procedure. This report is of a 68-year-old woman treated with laparoscopic-assisted enterolithotomy for gallstone ileus which recurred. A 68-year-old woman with type 2 diabetes mellitus, hypertension, breast cancer, and end-stage renal disease on hemodialysis presented with a gallstone ileus and was surgically managed with successful laparoscopic-assisted enterolithotomy. Seven days after the initial surgery, she again presented with gallstone ileus requiring reoperation. A repeat laparoscopic-assisted enterolithotomy was performed with no complications and full resolution of her symptoms. Operative management of gallstone ileus and subsequent recurrence continues to be highly debated. With no randomized studies and limited data, there is no current gold standard surgical procedure for either setting. Simple laparoscopic-assisted enterolithotomy is the favored surgical technique as it is associated with decreased morbidity, mortality, operative time, and complications. This report demonstrates that a CT scan is crucial in differentiating recurrent gallstone ileus from postoperative ileus, with a repeat laparoscopic-assisted enterolithotomy providing a safe and effective treatment option. Moreover, patient follow up is essential for monitoring symptom resolution.
