Abstract
Background: In the difficult gallbladder, the rate of bile duct injury (BDI) remains high. To lessen iatrogenic biliary injury, we attempted to utilize indocyanine green (ICG)-guided fluorescence cholangiography during surgery to illuminate the extrahepatic biliary tract. Materials and Methods: According to admission criteria, 38 patients were diagnosed with difficult gallbladder and underwent percutaneous transhepatic gallbladder drainage (PTGBD). Consecutive patients who underwent ICG-assisted laparoscopic biliary surgery (n = 18, ICG group) or conventional laparoscopic biliary surgery (n = 20, white light [WL group) were enrolled in this study. ICG group received ICG fluorescent cholangiography via PTGBD tube during operation; 16 cases of laparoscopic cholecystectomy (LC) and 2 cases of LC plus laparoscopic common bile duct exploration (LC+LCBDE) were performed by fluorescent laparoscopy. In the WL group, 16 cases of LC, 1 case of laparoscopic subtotal cholecystectomy (LSC), and 3 cases of LC+LCBDE were performed under white light without ICG. Result: The biliary system was successfully established in the ICG group. Compared with the WL group, the anatomy of the Calot's triangle with severe abdominal adhesion or local inflammatory edema was more clearly displayed by fluorescence. Laparoscopic surgery was completed in both groups without conversion to laparotomy. There were no significant differences in surgery-related complications (P = .232) and postoperative hospital stay (P = .074) between the two groups. However, compared with the WL group, the ICG group had less intraoperative blood loss (P = .002) and shorter operation duration (P = .006). Conclusion: ICG fluorescence cholangiography has good clinical application value in the difficult gallbladder, which can avoid iatrogenic BDI, reduce surgery-related complications and intraoperative blood loss, and shorten the duration of surgery.

Abstract
OBJECTIVE Near-infrared fluorescence cholangiography (NIRF-C) can help to identify the bile duct during laparoscopic cholecystectomy. This retrospective study was performed to investigate the effect of NIRF-C in laparoscopic cholecystectomy. METHODS Consecutive patients who underwent NIRF-C-assisted laparoscopic cholecystectomy (n = 34) or conventional laparoscopic cholecystectomy (n = 36) were enrolled in this study. Identification of biliary structures, the operation time, intraoperative blood loss, and postoperative complications were analyzed. RESULTS Laparoscopic cholecystectomy was completed in all patients without conversion to laparotomy. The median operation time and intraoperative blood loss were not significantly different between the two groups. No intraoperative injuries or postoperative complications occurred in either group. In the NIRF-C group, the visualization rate of the cystic duct, common bile duct, and common hepatic duct prior to dissection was 91%, 79%, and 53%, respectively. The success rate of cholangiography was 100% in the NIRF-C group. NIRF-C was more effective for visualizing biliary structures in patients with a BMI of <25 than >25 kg/m2. CONCLUSIONS NIRF-C is a safe and effective technique that enables real-time identification of the biliary anatomy during laparoscopic cholecystectomy. NIRF-C helps to improve the efficiency of dissection.

Abstract
To investigate the clinical application ofthe "three lines and one plane" concept as the anatomic landmarks during laparoscopic common bile duct exploration (LCBDE).From January 2014 to February 2017, 148 cases of LCBDE performed in the General Surgery Department of the 2nd affiliated Hospital of Anhui Medical University were recruited, and analyzed in this study. "Three lines and one plane" was applied as anatomical landmarks during LCBDE, and the perioperative clinical outcomes were analyzed.No serious operational complications occurred in all the patients in this study. Two cases (1.4%) was converted to open operation. Two other cases (1.4%) suffered post-operative bile leakage and were cured by conservative treatment. All patients recovered uneventfully.Anatomical landmarks of "three lines and one plane" is benefit in helping surgeons to build a three-dimensional (3D) anatomical construction, and avoiding the operative injury of the bile duct, and vessels.

Abstract
Background Intraoperative cholangiography (IOC) may detect residual stones in the common bile duct (CBD) after acute biliary pancreatitis (ABP). The aim of the present study is to analyze the utility of IOC in detecting residual stones in patients undergoing cholecystectomy for ABP and if complications are related with this procedure. Methods Demographic and clinical factors were assessed in patients with mild ABP who underwent IOC during laparoscopic cholecystectomy. Factors assessed included preoperative size of the CBD on ultrasonography, presence of stones in the gallbladder and the CBD, and IOC results. For the statistical analysis, χ2 or Fisher’s exact tests to compare proportions and the nonparametric Mann–Whitney U test for analysis of values with abnormal distribution were used. Results The study included 113 patients, 82 males (72.6%) and 31 females (27.4%), of mean age 46.9 ± 14.7 years (range 18–86 years). All preoperative laboratory indicators were elevated. The group of the patients with stones in the CBD diagnosed by IOC was divided in patients with diameters <0.8 mm and with diameters ≥0.8 mm of the CBD diagnosed preoperatively with ultrasound. The laboratory tests do not demonstrate difference statistically significative between these two groups. The group of the patients without stones in the CBD diagnosed by IOC was also divided in patients with diameters <0.8 mm and with diameters ≥0.8 mm of the CBD. Also in these two groups, the statistical analysis of the laboratory tests does not demonstrate significative difference. Most procedures were performed by specialists (64.6%), and all patients underwent IOC. IOC showed stones in 84/113 patients (74.3%). A comparison of patients with and without stones at IOC showed similar mean times from hospitalization to surgery (5.9 days [range 2–12 days] vs. 6.1 days [range 2–23 days]), from surgery until hospital discharge (2.0 days [range 0–4 days] vs. 2.2 days [range 0–11 days]), and overall length of stay (7.9 days [range 3–19 days] vs. 8.3 days [range 3–23 days]) (P > 0.001). Conclusions IOC is useful to diagnose residual CBD stones, without increasing complications related to the procedure itself.

Abstract
BACKGROUND Although rare, injury to the common bile duct (CBD) during laparoscopic cholecystectomy (LC) can be reduced by better intraoperative visualization of the cystic duct (CD) and CBD. The aim of this study was to establish the efficacy of early visualization of the CD and the added value of CBD identification, using near-infrared (NIR) light and the fluorescent agent indocyanine green (ICG), in patients at increased risk of bile duct injury. MATERIALS AND METHODS Patients diagnosed with complicated cholecystitis and scheduled for LC were included. The CBD and CD were visualized with NIR light before and during dissection of the liver hilus and at critical view of safety (CVS). RESULTS Of the 20 patients originally included, 2 were later excluded due to conversion. In 6 of 18 patients, the CD was visualized early during dissection and prior to imaging with conventional white light. The CBD was additionally visualized with ICG-NIR in 7 of 18 patients. In 1 patient, conversion was prevented due to detection of the CD and CBD with ICG-NIR. CONCLUSIONS Early visualization of the CD or additional identification of the CBD using ICG-NIR in patients with complicated cholecystolithiasis can be helpful in preventing CBD injury. Future studies should attempt to establish the optimal dosage and time frame for ICG administration and bile duct visualization with respect to different gallbladder pathologies.

Abstract
BACKGROUND The role of intraoperative cholangiography (IOC) in the diagnosis, prevention and management of bile duct injury (BDI) remains controversial. The aim of the present study was to determine the value of routine IOC in the diagnosis and management of BDI sustained during laparoscopic cholecystectomy (LC) at a high-volume centre. METHODS A retrospective analysis of a single-institution database was performed. Patients who underwent LC with routine IOC between October 1991 and May 2012 were included. RESULTS Among 11,423 consecutive LCs IOC was performed successfully in 95.7 per cent of patients. No patient had IOC-related complications. Twenty patients (0.17 per cent) sustained a BDI during LC, and the diagnosis was made during surgery in 18 patients. Most BDIs were type D according to the Strasberg classification. The sensitivity of IOC for the detection of BDI was 79 per cent; specificity was 100 per cent. All injuries diagnosed during surgery were repaired during the same surgical procedure. Two patients developed early biliary strictures that were treated by percutaneous dilatation and a Roux-en-Y hepaticojejunostomy with satisfactory long-term results. CONCLUSION The routine use of IOC during LC in a high-volume teaching centre was associated with a low incidence of BDI, and facilitated detection and repair during the same surgical procedure with a good outcome.

Abstract
Gallstone disease is one of the most common problems in the gastroenterology and is associated with significant morbidity. It may present as stones in the gallbladder (cholecystolithiasis) or in the common bile duct (choledocholithiasis). At the end of the 1980s laparoscopy was introduced and first laparoscopic cholecystectomy was performed in 1985. The laparoscopic technique for removing the gallbladder is the current treatment of choice, although indications for open surgery exist. To perform laparoscopic cholecystectomy as safe as possible multiple safety measures were developed. The gold standard for diagnosing and removing common bile duct stones is Endoscopic Retrograde Cholangiopancreatography (ERCP). The surgical treatment option for choledocholithiasis is laparoscopic cholecystectomy with common bile duct exploration. If experience is not available, than ERCP followed by elective cholecystectomy is by far the best therapeutic modality. The present review will discuss the use, benefits and drawbacks of laparoscopy in patients with cholecystolithiasis and choledocholithiasis.

Abstract
IMPORTANCE Significant controversy exists regarding routine intraoperative cholangiography in preventing common duct injury during cholecystectomy. OBJECTIVE To investigate the association between intraoperative cholangiography use during cholecystectomy and common duct injury. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study of all Texas Medicare claims data from 2000 through 2009. We identified Medicare beneficiaries 66 years or older who underwent inpatient or outpatient cholecystectomy for biliary colic or biliary dyskinesia, acute cholecystitis, or chronic cholecystitis. We compared results from multilevel logistic regression models to the instrumental variable analyses. INTERVENTIONS Intraoperative cholangiography use during cholecystectomy was determined at the level of the patients (yes/no), hospitals (percentage intraoperative cholangiography use for all cholecystectomies at the hospital), and surgeons (percentage use for all cholecystectomies performed by the surgeon). Percentage of use at the hospital and percentage of use by surgeon were the instrumental variables. MAIN OUTCOMES AND MEASURES Patients with claims for common duct repair operations within 1 year of cholecystectomy were considered as having major common duct injury. RESULTS Of 92,932 patients undergoing cholecystectomy, 37,533 (40.4%) underwent concurrent intraoperative cholangiography and 280 (0.30%) had a common duct injury. The common duct injury rate was 0.21% among patients with intraoperative cholangiography and 0.36% among patients without it. In a logistic regression model controlling for patient, surgeon, and hospital characteristics, the odds of common duct injury for cholecystectomies performed without intraoperative cholangiography were increased compared with those performed with it (OR, 1.79 [95% CI, 1.35-2.36]; P < .001). When confounding was controlled with instrumental variable analysis, the association between cholecystectomy performed without intraoperative cholangiography and duct injury was no longer significant (OR, 1.26 [95% CI, 0.81-1.96]; P = .31). CONCLUSIONS AND RELEVANCE When confounders were controlled with instrumental variable analysis, there was no statistically significant association between intraoperative cholangiography and common duct injury. Intraoperative cholangiography is not effective as a preventive strategy against common duct injury during cholecystectomy.

Abstract
BACKGROUND Few studies of laparoscopic cholecystectomy (LC) outcome have used longitudinal data for more than two years. Moreover, no studies have considered group differences in factors other than outcome such as age and nonsurgical treatment. Additionally, almost all published articles agree that the essential issue of the internal validity (reproducibility) of the artificial neural network (ANN), support vector machine (SVM), Gaussian process regression (GPR) and multiple linear regression (MLR) models has not been adequately addressed. This study proposed to validate the use of these models for predicting quality of life (QOL) after LC and to compare the predictive capability of ANNs with that of SVM, GPR and MLR. METHODOLOGY/PRINCIPAL FINDINGS A total of 400 LC patients completed the SF-36 and the Gastrointestinal Quality of Life Index at baseline and at 2 years postoperatively. The criteria for evaluating the accuracy of the system models were mean square error (MSE) and mean absolute percentage error (MAPE). A global sensitivity analysis was also performed to assess the relative significance of input parameters in the system model and to rank the variables in order of importance. Compared to SVM, GPR and MLR models, the ANN model generally had smaller MSE and MAPE values in the training data set and test data set. Most ANN models had MAPE values ranging from 4.20% to 8.60%, and most had high prediction accuracy. The global sensitivity analysis also showed that preoperative functional status was the best parameter for predicting QOL after LC. CONCLUSIONS/SIGNIFICANCE Compared with SVM, GPR and MLR models, the ANN model in this study was more accurate in predicting patient-reported QOL and had higher overall performance indices. Further studies of this model may consider the effect of a more detailed database that includes complications and clinical examination findings as well as more detailed outcome data.
