Factors related to residual gallbladder calculi formation using computed tomography and magnetic resonance imaging combined with clinical data

Abstract

Objective We aimed to investigate risk factors related to remnant gallbladder (RGB) stones. Methods This retrospective study included 73 patients with RGB, in groups with and without RGB calculi. Univariate analyses were used to identify nine variables associated with RGB calculi: sex, age, body mass index (BMI), time to detection, surgical method, length of RGB, angle of RGB and common hepatic duct (CHD), choledocholithiasis, and remnant cholecystitis. Multivariate logistic regression was performed to assess independent predictors of RGB stones. A receiver operating characteristic (ROC) curve was used to estimate model accuracy and determine cut-off values of independent predictors. Results We enrolled 73 patients, 33 with and 40 without RGB stones. Univariate analyses showed that age, BMI, time to detection, length of RGB, angle of RGB and CHD were predictors for RGB calculi. Multivariate analyses indicated that time to detection, length of RGB, and angle of RGB and CHD were independent predictors for RGB calculi. The area under the ROC curve of the model was 0.940. Cut-off values of the three indicators were 1.5 years, 2.25 cm, and 22.5°, respectively. Conclusion Time to detection, length of RGB, and angle of RGB and CHD were independent predictors of RGB calculi.

Laparoscopic remnant cholecystectomy for calculi in the remnant gallbladder following subtotal-cholecystectomy: a report of two cases

“…The rate of remnant cystic duct/gallbladder calculi is reported to be 4.19% following SC [5], and the rate of remnant cholecystitis after SC is 1.4% [6]. In studies that have reported treatment of remnant cholecystitis [6] and symptomatic remnant calculi [8][9][10][11][12], the majority of patients required remnant cholecystectomy. Prior to remnant cholecystectomy, preoperative examination of the biliary anatomy is important to avoid bile duct injury.…”

Surgical management of cystic duct stump calculi causing post-cholecystectomy syndrome: A prospective study

“…A similar observation was made by other researchers as well. [ 15 , 16 , 20 , 21 ] This suggests that remnant gallbladder or cystic duct stones are frequently encountered even after open cholecystectomy. Mistaken identification of gallbladder and cystic duct junction and subtotal cholecystectomies are the factors responsible for incomplete gallbladder removal.…”

“…have postulated that the small incision used in open cholecystectomy may result in inadequate exposure of Calot’s area, leading to incomplete gallbladder excision. [ 21 ]…”

“…Патологія печінки і жовчовивідної системи / Pathology of Liver and Biliary Excretion System examination, magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasonography allow in the vast majority of cases before surgery to establish the cause of bile passage violation in patients with CL in the preoperative period, perform decompression of the biliary tract during surgery, and then either eliminate the cause of bile passage violation with minimally invasive interventions, or prepare the patient for the next stage of surgical treatment [4][5][6][7][8][9]. However, it is not always possible to determine the cause of EHC in CL using modern diagnostic methods before and during surgery.…”
