Biliary Anatomy Visualization and Surgeon Satisfaction Using Standard Cholangiography versus Indocyanine Green Fluorescent Cholangiography during Elective Laparoscopic Cholecystectomy: A Randomized Controlled Trial. J Clin Med 2024; 13:864. [PMID: 38337557 PMCID: PMC10856121 DOI: 10.3390/jcm13030864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 01/26/2024] [Accepted: 01/28/2024] [Indexed: 02/12/2024] Open
Abstract
Background: Intraoperative biliary anatomy recognition is crucial for safety during laparoscopic cholecystectomy, since iatrogenic bile duct injuries represent a fatal complication, occurring in up to 0.9% of patients. Indocyanine green fluorescence cholangiography (ICG-FC) is a safe and cost-effective procedure for achieving a critical view of safety and recognizing early biliary injuries. The aim of this study is to compare the perioperative outcomes, usefulness and safety of standard intraoperative cholangiography (IOC) with ICG-FC with intravenous ICG. Methods: Between 1 June 2021 and 31 December 2022, 160 patients undergoing elective LC were randomized into two equal groups: Group A (standard IOC) and group B (ICG-FC with intravenous ICG). Results: No significant difference was found between the two groups regarding demographics, surgery indication or surgery duration. No significant difference was found regarding the visualization of critical biliary structures. However, the surgeon satisfaction and cholangiography duration presented significant differences in favor of ICG-FC. Regarding the inflammatory response, a significant difference between the two groups was found only in postoperative WBC levels. Hepatic and renal function test results were not significantly different between the two groups on the first postoperative day, except for direct bilirubin. No statistically significant difference was noted regarding 30-day postoperative complications, while none of the complications noted included bile duct injury events. Conclusions: ICG-FC presents equivalent results to IOC regarding extrahepatic biliary visualization and postoperative complications. However, more studies need to be performed in order to standardize the optimal dose, timing and mode of administration.

The Use of Intraoperative Cholangiography During Cholecystectomy: A Systematic Review. Cureus 2023; 15:e47646. [PMID: 37899894 PMCID: PMC10612988 DOI: 10.7759/cureus.47646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/25/2023] [Indexed: 10/31/2023] Open
Abstract
Cholecystectomy is a widespread surgical procedure for gallbladder diseases. Evolving techniques and technologies, such as intraoperative cholangiography (IOC), enhance safety and outcomes by providing real-time biliary system visualization during surgery. This systematic review explored available data on using IOC during cholecystectomy, highlighting its effectiveness, safety, and cost-effectiveness. To perform this systematic review, a thorough literature search was conducted using relevant keywords in electronic databases, such as PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), Cochrane Library, Web of Science, and Google Scholar. We included studies published during the last 10 years exploring the use of IOC during cholecystectomy. The findings showed success rates of up to 90% with a median time of 21.9 minutes without complications. Most (90%) patients with acute gallstone pancreatitis underwent cholecystectomy with IOC, with unclear IOC results in 10.7% and failure in 14.7%. IOC failure factors included age, body mass index (BMI), male sex, concurrent acute cholecystitis, common bile duct (CBD) stone evidence on imaging, CBD diameter of >6 mm, total bilirubin of >4 mg/dL, abnormal liver tests, and gallstone pancreatitis. The detection of choledocholithiasis by IOC prompted trans-cystic duct exploration and endoscopic retrograde cholangiopancreatography (ERCP). Biliary abnormalities and stone identification were observed using IOC, and routine use increased bile duct stone detection while decreasing bile duct injury and readmission rates. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of IOC for common bile duct stone detection were reported at 77%, 98%, 97.2%, 63%, and 99%, respectively. Routine IOC was projected to provide substantial quality-adjusted life years (QALY) and cost-effectiveness gains compared to selective IOC. Regarding safety, IOC was generally associated with reduced complication and open surgery conversion risks, with similar rates of CBD injury and bile leaks. These findings indicate that IOC enhances cholecystectomy outcomes through precision and decreasing complications.

Detection of the communicating accessory bile duct in laparoscopic resection of residual gallbladder by the combination of the indocyanine green fluorescence cholangiography and the intraoperative cholangiography: A case report. Photodiagnosis Photodyn Ther 2023; 42:103587. [PMID: 37146895 DOI: 10.1016/j.pdpdt.2023.103587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 04/26/2023] [Accepted: 04/28/2023] [Indexed: 05/07/2023]
Abstract
BACKGROUND The partial cholecystectomy may be performed while in complicated laparoscopic cholecystectomy (LC). Biliary anomalies especially the accessory bile duct are established high risk of bile duct injury (BDI) in LC. Laparoscopic resection of residual gallbladder is a challenging procedure and extremely vulnerable to BDI. We report the execution of a laparoscopic resection of residual gallbladder with a communicating accessory bile duct using indocyanine green (ICG) fluorescence cholangiography and the intraoperative cholangiography (IOC). A case that has not been reported previously. PRESENTATION OF CASE A 29-year-old female with history of laparoscopic partial cholecystectomy was admitted in our hospital. Magnetic resonance cholangiopancreatography (MRCP) revealed the residual gallbladder with an accessory bile duct. Considering the complexity of this patient, we performed a laparoscopic surgery using ICG fluorescence cholangiography. ICG was injected intravenously 1h before the surgery, the residual gallbladder and the extrahepatic biliary structures including the accessory bile duct were imaged in green in fluorescence imaging that could be recognized clearly. IOC revealed that residual gallbladder communicated with intrahepatic bile duct through the accessory bile duct and drained into the common bile duct (CBD). The entire procedure was performed smoothly and successfully without bile duct injuries. DISCUSSION Laparoscopic resection of residual gallbladder is a challenging procedure. Fluorescence cholangiography using ICG is regarded as a novel technique that could provide a real-time imaging intraoperative, which allowed to recognize and identify the residual gallbladder and the extrahepatic bile duct. IOC is also important in identifying a communicating accessory bile duct. Under the guidance of them, we completed this laparoscopic surgery. CONCLUSIONS The combination of fluorescence cholangiography using ICG and IOC have profound significance in complicated LC.

A case of accessory hepatic duct entering cystic duct successfully treated by laparoscopic cholecystectomy for cholecystolithiasis. Asian J Endosc Surg 2023. [PMID: 36944530 DOI: 10.1111/ases.13175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 02/14/2023] [Accepted: 02/19/2023] [Indexed: 03/23/2023]
Abstract
Although laparoscopic cholecystectomy is a well-established surgical procedure, an accessory hepatic duct (AcHD) entering the cystic duct is poorly understood. A 77-year-old woman with symptomatic cholecystlithiasis was referred to our hospital. Abdominal ultrasonography indicated several small stones in the gall bladder. Magnetic resonance cholangiopancreatography (MRCP) did not reveal an anomalous cystic duct. Dissecting the gall bladder bed at operation, AcHD entering the cystic duct was suspected. Intraoperative cholangiography revealed that B5 branch entered the cystic duct. We ligated the AcHD, and divided it. Laparoscopic cholecystectomy was completed, and the patient was discharged without any complication. A week after the operation, MRCP showed that ventral branch of B5 was dilated. The patient showed no symptom for more than a year. The present case exhibited extremely rare AcHD entering the cystic duct, which was hardly recognized before surgery. It is possible to recognize such anomalous variants with standard laparoscopic approach based on 2018 Tokyo Guidelines and with attention to the possibilities of AcHD entering the cystic duct.

Precision Mapping of Intrahepatic Biliary Anatomy and Its Anatomical Variants Having a Normal Liver Using 2D and 3D MRCP. Diagnostics (Basel) 2023; 13:diagnostics13040726. [PMID: 36832212 PMCID: PMC9955884 DOI: 10.3390/diagnostics13040726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 02/05/2023] [Accepted: 02/11/2023] [Indexed: 02/17/2023] Open
Abstract
Despite significant advances in hepatobiliary surgery, biliary injury and leakage remain typical postoperative complications. Thus, a precise depiction of the intrahepatic biliary anatomy and anatomical variant is crucial in preoperative evaluation. This study aimed to evaluate the precision of 2D and 3D magnetic resonance cholangiopancreatography (MRCP) in exact mapping of intrahepatic biliary anatomy and its variants anatomically in subjects with normal liver using intraoperative cholangiography (IOC) as a reference standard. Thirty-five subjects with normal liver activity were imaged via IOC and 3D MRCP. The findings were compared and statistically analyzed. Type I was observed in 23 subjects using IOC and 22 using MRCP. Type II was evident in 4 subjects via IOC and 6 via MRCP. Type III was observed equally by both modalities (4 subjects). Both modalities observed type IV in 3 subjects. The unclassified type was observed in a single subject via IOC and was missed in 3D MRCP. Accurate detection by MRCP of intrahepatic biliary anatomy and its anatomical variants was made in 33 subjects out of 35, with an accuracy of 94.3% and a sensitivity of 100%. In the remaining two subjects, MRCP results provided a false-positive pattern of trifurcation. MRCP competently maps the standard biliary anatomy.

Intracholecystic versus Intravenous Indocyanine Green (ICG) Injection for Biliary Anatomy Evaluation by Fluorescent Cholangiography during Laparoscopic Cholecystectomy: A Case-Control Study. J Clin Med 2022; 11:jcm11123508. [PMID: 35743577 PMCID: PMC9224771 DOI: 10.3390/jcm11123508] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Revised: 06/10/2022] [Accepted: 06/15/2022] [Indexed: 11/16/2022] Open
Abstract
(1) Background: Fluorescence cholangiography has been proposed as a method for improving the visualization and identification of extrahepatic biliary anatomy in order to possibly reduce injuries and related complications. The most common method of indocyanine green (ICG) administration is the intravenous route, whereas evidence on direct ICG injection into the gallbladder is still quite limited. We aimed to compare the two different methods of ICG administration in terms of the visualization of extrahepatic biliary anatomy during laparoscopic cholecystectomy (LC), analyzing differences in the time of visualization, as well as the efficacy, advantages, and disadvantages of both modalities. (2) Methods: A total of 35 consecutive adult patients affected by acute or chronic gallbladder disease were enrolled in this prospective case−control study. Seventeen patients underwent LC with direct gallbladder ICG injection (IC-ICG) and eighteen subjects received intravenous ICG administration (IV-ICG). (3) Results: The groups were comparable with regard to their demographic and perioperative characteristics. The IV-ICG group had a significantly shorter overall operative time compared to the IC-ICG group (p = 0.017). IV-ICG was better at delineating the duodenum and the common hepatic duct compared to the IC-ICG method (p = 0.009 and p = 0.041, respectively). The cystic duct could be delineated pre-dissection in 76.5% and 66.7% of cases in the IC-ICG and IV-ICG group, respectively, and this increased to 88.2% and 83.3% after dissection. The common bile duct could be highlighted in 76.5% and 77.8% of cases in the IC-ICG and IV-ICG group, respectively. Liver fluorescence was present in one case in the IC-ICG group and in all cases after IV-ICG administration (5.8% versus 100%; p < 0.0001). (4) Conclusions: The present study demonstrates how ICG-fluorescence cholangiography can be helpful in identifying the extrahepatic biliary anatomy during dissection of Calot’s triangle in both administration methods. In comparison with intravenous ICG injection, the intracholecystic ICG route could provide a better signal-to-background ratio by avoiding hepatic fluorescence, thus increasing the bile duct-to-liver contrast.

Retrospective Analysis of the Accuracy of High-Frequency Ultrasound for Pancreaticobiliary Maljunction in Pediatrics at a Single Center. Front Pediatr 2022; 10:775378. [PMID: 35498787 PMCID: PMC9047754 DOI: 10.3389/fped.2022.775378] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 02/08/2022] [Indexed: 11/18/2022] Open
Abstract
OBJECTIVE To determine the clinical value of high-frequency ultrasonography (US) in the evaluation and diagnosis of pancreaticobiliary maljunction (PBM) among children. METHODS The clinical subjects consisted of 31 pediatric patients who were diagnosed with PBM from January 2015 to May 2021 in Fujian Provincial Maternity and Children's Hospital. The primary outcomes included diagnosis accuracy, imaging characteristics of each type of PBM based on JSPBM, time length of operation, and cost of service. Secondary outcomes were the serum amylase and bilirubin levels. RESULTS The diagnostic accuracy of US was 90.3% and comparable to the other imaging methods-MRCP (82.6%), IOC (79.2%), and ERCP (100%), respectively. The time length of operation and direct cost were significantly lower than other imaging pathways. Stenotic type (A) is associated with a high internal diameter of CBD, and dilated channel type (C) presents increased internal diameter and length of CC as well as internal diameter of PD. There were higher levels of the serum bilirubin seen in type A and of serum amylase in type C compared with others. CONCLUSION High-frequency US is a safe, cost-effective, and non-invasive imaging tool for the diagnosis and evaluation of PBM in pediatrics.

Bile Duct Injury During Cholecystectomy: Necessity to Learn How to Do and Interpret Intraoperative Cholangiography. Front Med (Lausanne) 2021; 8:637987. [PMID: 33681264 PMCID: PMC7925835 DOI: 10.3389/fmed.2021.637987] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Accepted: 01/14/2021] [Indexed: 12/24/2022] Open
Abstract
Introduction: Biliary duct injury (BDI) is a serious complication during cholecystectomy. Perioperative cholangiography (POC) has recently been generating interest in order to prevent BDI. However, the current literature (including randomized controlled trials) cannot conclude whether POC is protective or not against the risk of BDI. The aim of our study was to investigate whether POC could demonstrate earlier BDI and which criteria are required to make that diagnosis. Methods: We performed a retrospective study between 2005 and 2018 in our French tertiary referral center, which included all patients who had presented following BDI during cholecystectomy. Results: Twenty-two patients were included. Nine patients had POC, whereas 13 did not. When executed, POC was interpreted as normal for three patients and abnormal for six. In this latter group, only two cases had a BDI diagnosed intraoperatively. In other cases, the interpretation was not adequate. Conclusion: BDIs are rare but may reduce patients' quality of life. Our study highlights the surgeon's responsibility to learn how to perform and interpret POC in order to diagnose and manage BDIs and potentially avoid catastrophic consequences.

Comparison of Endoscopy First and Laparoscopic Cholecystectomy First Strategies for Patients With Gallstone Disease and Intermediate Risk of Choledocholithiasis: Protocol for a Clinical Randomized Controlled Trial. JMIR Res Protoc 2021; 10:e18837. [PMID: 33538700 PMCID: PMC7892280 DOI: 10.2196/18837] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 08/04/2020] [Accepted: 11/10/2020] [Indexed: 12/22/2022] Open
Abstract
Background The optimal approach for patients with gallbladder stones and intermediate risk of choledocholithiasis remains undetermined. The use of endoscopic retrograde cholangiopancreatography for diagnosis should be minimized as it carries considerable risk of postprocedural complications, and nowadays, less invasive and safer techniques are available. Objective This study compares the two management strategies of endoscopic ultrasound before laparoscopic cholecystectomy and intraoperative cholangiography for patients with symptomatic cholecystolithiasis and intermediate risk of choledocholithiasis. Methods This is a randomized, active-controlled, single-center clinical trial enrolling adult patients undergoing laparoscopic cholecystectomy for symptomatic gallbladder stones with intermediate risk of choledocholithiasis. The risk of choledocholithiasis is calculated using an original prognostic score (the Vilnius University Hospital Index). This index in a retrospective evaluation showed better prognostic performance than the score proposed by the American Society for Gastrointestinal Endoscopy in 2010. A total of 106 participants will be included and randomized into two groups. Evaluation of bile ducts using endoscopic ultrasound and endoscopic retrograde cholangiography on demand will be performed before laparoscopic cholecystectomy for one arm (“endoscopy first”). Intraoperative cholangiography during laparoscopic cholecystectomy and postoperative endoscopic retrograde cholangiopancreatography on demand will be performed in another arm (“cholecystectomy first”). Postoperative follow-up is 6 months. The primary endpoint is the length of hospital stay. The secondary endpoints are accuracy of the different management strategies, adverse events of the interventions, duct clearance and technical success of the interventions (intraoperative cholangiography, endoscopic ultrasound, and endoscopic retrograde cholangiography), and cost of treatment. Results The trial protocol was approved by the Vilnius Regional Biomedical Research Ethics Committee in December 2017. Enrollment of patients was started in January 2018. As of June 2020, 66 patients have been enrolled. Conclusions This trial is planned to determine the superior strategy for patients with intermediate risk of common bile duct stones and to define a simple and safe algorithm for managing choledocholithiasis.

Abstract
Background: Management of bile duct injury (BDI) after cholecystectomy is challenging. The authors analyzed their center's 49-year experience.Methods: From 1968 to 2016, 120 consecutive patients were managed in a tertiary HBP center, 105 referred from other centers (Group A), 15 from our center (Group B). Surgical strategies and long-term outcomes were retrospectively reviewed.Results: Primary cholecystectomy approach was open in 35% and laparoscopic in 65%. In Group A, intraoperative BDI diagnosis was made in 25/105 patients, including 13 via intraoperative cholangiography (IOC) which was used in 21% of cases. Median time from BDI to referral was 148 days (range 0-10,758), and 3 patients had BDI-related secondary cirrhosis. Ninety-four patients underwent secondary surgical repair, mostly a complex biliary procedure (97%). Postoperative overall and severe morbidity rates were 26% and 6%, respectively. One patient with biliary cirrhosis at referral died postoperatively from hepatic failure. Nine patients (9.6%) developed a secondary biliary stricture after a median of 54 months from repair (6-228 months). In Group B, IOC was performed in 14/15 in whom BDI were intraoperatively detected and immediately repaired. There were 13 minor and 2 major BDIs, all repaired by uncomplex procedures with uneventful postoperative course. One patient had a secondary biliary stricture after 5 months, successfully treated by temporary endoprosthesis.Conclusion: Late follow-up after primary or secondary repair of BDI is recommended to detect recurrent biliary stricture. Bile duct injuries may occur in a tertiary center, but are intraoperatively detected with routine IOC and immediately repaired resulting in satisfactory outcome.

Abstract
Cholecystectomy is the only definitive management of pancreatitis secondary to gallstone disease. Approximately 20% to 30% of patients with acute biliary pancreatitis (ABP) will have persistent common bile duct (CBD) stones. Therefore, choosing a method for the early diagnosis of choledocholithiasis is essential to reduce waiting days for surgery and hospital stay in these patients.The aim of this study was to compare the use of magnetic resonance cholangiography (MRC) and intraoperative cholangiography (IOC), and its impact on the length of the hospital stay in patients with mild ABP and an intermediate probability of choledocholithiasis.We prospectively evaluated all patients diagnosed with mild ABP and an intermediate probability of choledocholithiasis at admission and 48 hours after, from June, 2017 to December, 2017. Study subjects were identified upon admission and were classified into 2 groups of patients according to their choledocholithiasis predictors; a MRC was performed in the group 1, and an IOC was done in group 2.In all, 47 patients were enrolled in the final analysis of this study. Hospital stay in group 1 (CMR) patients was 8.29 (±2.69) days compared with 6.43 (±2.57) days in the group 2 (IOC) (P = .007). Mean waiting days for cholecystectomy was 17.14 (±26.04) days for group 1 and 5 (±2.69) days for group 2.We suggest an IOC as the election method for the diagnosis of CBD stones in patients with mild ABP in medical centers similar to ours because it reduces waiting days for surgery and hospital stay compared to the MRC.

Abstract
Background Accurate risk evaluation of choledocholithiasis prior to laparoscopic cholecystectomy is essential to determine optimal management strategy. Objective Our study aimed to evaluate the accuracy of separate predictors and Vilnius University Hospital Index (VUHI = A/30 + 0.4 × B; A = total bilirubin concentration (µmol/l), B = common bile duct (CBD) diameter (mm) measured by ultrasound) diagnosing choledocholithiasis and to assess different management strategies (cholecystectomy with intraoperative cholangiography and endoscopic retrograde cholangiopancreatography (ERCP)). Methods The retrospective study included 350 patients admitted to a tertiary care centre for laparoscopic cholecystectomy for cholecystolithiasis who were investigated for concomitant choledocholithiasis. Results Choledocholithiasis was diagnosed in 182 (76.2%) cases in the high-risk group (VUHI value ≥4.7) and 44 (39.6%) in the low, odds ratio is 4.86 (95% CI: 3.00-7.88). Its sensitivity was 80.5%, specificity 54.0%, accuracy 71.1%. Dilated CBD had the highest sensitivity (92.5%) of predictors.ERCP showed better diagnostic performance than intraoperative cholangiography. Complications of ERCP were more frequent for patients without stones. There was no significant difference of outcomes between the two management strategies. Conclusion The prognostic index has good diagnostic accuracy but dividing patients into two risk groups is insufficient. The suggested model allows determining an intermediate-risk group, which requires additional investigation. Both management approaches are appropriate.

Mechanism of dynamic near-infrared fluorescence cholangiography of extrahepatic bile ducts and applications in detecting bile duct injuries using indocyanine green in animal models. ACTA ACUST UNITED AC 2017; 37:44-50.

Abstract
Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG). However, the dynamic process and mechanism of fluorescence IOC have not been elucidated in previous publications. Herein, the optical properties of the complex of ICG and bile, dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated. The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration. Extrahepatic bile ducts could fluoresce 2 min after intravenous injection, and the fluorescence intensity reached a peak at 8 min. In addition, biliary dynamics were observed owing to ICG excretion from the bile ducts into the duodenum. Quantitative analysis indicated that ICG-guided fluorescence IOC possessed a high signal to noise ratio compared to the surrounding peripheral tissue and the portal vein. Fluorescence IOC was based on rapid uptake of circulating ICG in plasma by hepatic cells, excretion of ICG into the bile and then its interaction with protein molecules in the bile. Moreover, fluorescence IOC was sensitive to detect bile duct ligation and acute bile duct perforation using ICG in rat models. All of the results indicated that fluorescence IOC using ICG is a valid alternative for the cholangiography of extrahepatic bile ducts and has potential for measurement of biliary dynamics.

Abstract
In hepatobiliary surgery, the fluorescence and bile excretion of indocyanine green (ICG) can be used for real-time visualization of biological structure. Fluorescence cholangiography is used to obtain fluorescence images of the bile ducts following intrabiliary injection of 0.025-0.5 mg/mL ICG or intravenous injection of 2.5 mg ICG. Recently, the latter technique has been used in laparoscopic/robotic cholecystectomy. Intraoperative fluorescence imaging can be used to identify subcapsular hepatic tumors. Primary and secondary hepatic malignancy can be identified by intraoperative fluorescence imaging using preoperative intravenous injection of ICG through biliary excretion disorders that exist in cancerous tissues of hepatocellular carcinoma (HCC) and in non-cancerous hepatic parenchyma around adenocarcinoma foci. Intraoperative fluorescence imaging may help detect tumors to be removed, especially during laparoscopic hepatectomy, in which visual inspection and palpation are limited, compared with open surgery. Fluorescence imaging can also be used to identify hepatic segments. Boundaries of hepatic segments can be visualized following injection of 0.25-2.5 mg/mL ICG into the portal veins or by intravenous injection of 2.5 mg ICG following closure of the proximal portal pedicle toward hepatic regions to be removed. These techniques enable identification of hepatic segments before hepatectomy and during parenchymal transection for anatomic resection. Advances in imaging systems will increase the use of fluorescence imaging as an intraoperative navigation tool that can enhance the safety and accuracy of open and laparoscopic/robotic hepatobiliary surgery.

Abstract
Recent technological advances have enabled real-time near-infrared fluorescence cholangiography (NIRFC) with indocyanine green (ICG). Whereas several studies have shown its feasibility, dosing and timing for practical use have not been optimized. We undertook a prospective study with systematic variation of dosing and timing from injection of ICG to visualization. Adult patients undergoing laparoscopic biliary and hepatic operations were enrolled. Intravenous ICG (0.02-0.25 mg/kg) was administered at times ranging from 10 to 180 minutes prior to planned visualization. The porta hepatis was examined using a dedicated laparoscopic system equipped to detect NIRFC. Quantitative analysis of intraoperative fluorescence was performed using a scoring system to identify biliary structures. A total of 37 patients were enrolled. Visualization of the extrahepatic biliary tract improved with increasing doses of ICG, with qualitative scores improving from 1.9 ± 1.2 (out of 5) with a 0.02-mg/kg dose to 3.4 ± 1.3 with a 0.25-mg/kg dose (P < .05 for 0.02 vs 0.25 mg/kg). Visualization was also significantly better with increased time after ICG administration (1.1 ± 0.3 for 10 minutes vs 3.4 ± 1.1 for 45 minutes, P < .01). Similarly, quantitative measures also improved with both dose and time. There were no complications from the administration of ICG. These results suggest that a dose of 0.25 mg/kg administered at least 45 minutes prior to visualization facilitates intraoperative anatomical identification. The dosage and timing of administration of ICG prior to intraoperative visualization are within a range where it can be administered in a practical, safe, and effective manner to allow intraoperative identification of extrahepatic biliary anatomy using NIRFC.

Clinical significance of bile reflux into the pancreatic duct without pancreaticobiliary maljunction assessed by intraoperative cholangiography. Asian J Endosc Surg 2015; 8:296-302. [PMID: 25756368 DOI: 10.1111/ases.12181] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2014] [Revised: 01/22/2015] [Accepted: 01/25/2015] [Indexed: 12/26/2022]
Abstract
INTRODUCTION Bile reflux into the pancreatic duct (BRPD) is sometimes demonstrated during intraoperative cholangiography (IOC) even in patients without pancreaticobiliary maljunction. However, the clinical significance of this finding in laparoscopic and open cholecystectomy is unclear. METHODS Among 484 patients who underwent cholecystectomy (372 laparoscopic, 112 open), patients whose pancreatic duct was depicted in IOC were selected. The value of pancreatic amylase (p-amylase) of the gallbladder bile, histological changes, and the immunohistochemical expression of proliferating cell nuclear antigen (PCNA) in the gallbladder mucosa were analyzed in patients with BRPD. The data were then compared to those in patients without BRPD whose gallbladder bile p-amylase was measured (control group, n = 20). RESULTS The success rate of IOC was 93.6%. The rate of BRPD in laparoscopic and open cholecystectomy was 5.2% and 5.7%, respectively. The value of gallbladder bile p-amylase in patients with BRPD was significantly higher than in the control group (790.5 vs 14.0 IU/L, P = 0.034). The value of the PCNA labeling index in patients with BRPD was significantly higher than that of the control group (15.4% vs 4.1%, P = 0.0026). Among the 24 patients with BRPD, pathological changes in the gallbladder mucosa were detected in five (two hyperplasia, three metaplasia), but there was no correlation between the presence of pathological change and PCNA labeling index or gallbladder bile p-amylase. CONCLUSIONS IOC could detect BRPD both in laparoscopic and open cholecystectomy at a similar rate. Patients with BRPD had high levels of gallbladder bile p-amylase and PCNA labeling index, findings similar to those in patients with pancreaticobiliary maljunction.

A gallbladder with the "hidden cystic duct": A brief overview of various surgical techniques of the Calot's triangle dissection. Interv Med Appl Sci 2015; 7:42-5. [PMID: 25838927 DOI: 10.1556/imas.7.2015.1.4] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2014] [Revised: 11/24/2014] [Accepted: 12/08/2014] [Indexed: 01/05/2023] Open
Abstract
We present a case of a middle-aged female who attended for a routine laparoscopic cholecystectomy as a day case surgery. At operation, she was found to have a distended gallbladder with an unusually prominent distal portion. This has made the dissection of the Calot's triangle challenging. As a result, the "critical view of safety" technique was applied. This allowed for the clear Calot's triangle visualization and identification of the cystic duct and artery. This case highlights that the knowledge of various ways of the cystic duct dissection is essential to every surgeon. Furthermore, this helps to adjust the dissection approach on an individual case bases ensuring avoidance of the common bile duct injuries.

Abstract
Laparoscopic cholecystectomy is the standard treatment for patients requiring gallbladder removal. Although the advantages of the laparoscopic technique are widely accepted, the introduction of this technique has doubled the rate of iatrogenic lesions of extrahepatic bile ducts. Research methods for biliary tree also evolved, but intraoperative cholangiography, the traditional exploring method used for the biliary tree in classic cholecystectomy remains a valuable investigation in the laparoscopic technique. We performed a retrospective study on a group of patients who underwent cholecystectomy (laparoscopic or classic). Of these, intraoperative cholangiography was performed on a total of 108 patients. Patients who underwent cholangiography motivated by preoperative investigations were excluded from the group and the study operates on patients in whom the decision to perform cholangiography was taken during surgery (45 cases). We have analyzed the criteria that led to the motivation investigation (dilated cystic duct, suspected biliary duct stones, suspicion of iatrogenic biliary injury) results and subsequent therapeutic conduct. The results showed that in 90% of the patients, the suspected diagnosis was confirmed by cholangiography (10 cases with normal cholangiography aspect, oddita 9 cases, 11 cases with bile duct stones, 2 cases with biliary tumor and 13 cases of iatrogenic biliary injury). In conclusion, the decision to perform intraoperative cholangiography proved salutary, the suspected diagnosis was confirmed and the course of treatment was adjusted accordingly.

Abstract
BACKGROUND Pancreaticobiliary maljunction (PBM) is often associated with congenital choledochal cyst, protein plugs and pancreatitis. Early diagnosis and timely treatment largely depend on imaging. We assessed a series of PBM in children, comparing imaging procedure with histological and pathological findings with regard to diagnosis. METHODS A retrospective analysis was conducted in 75 pediatric patients with PBM. PBM was defined as common channel at >5 mm. Two radiologists assess the shape of the bile duct and gallbladder, pancreatitis, surgical pathology, symptom profiles, operative notes and pathological records were compared with the imaging findings. RESULTS Dilatation of the bile duct was detected in 45 subjects out of the 46 subjects who underwent computed tomography (CT) and nine was diagnosis as PBM. Forty out of 41 subjects were revealed bile duct dilatation in ultrasonography (US). Bile duct dilatation was seen in 59 out of 60 subjects receiving magnetic resonance cholangiopancreatography (MRCP) and 39 were diagnosed as PBM. Seventy-four out of 75 subjects successfully underwent intraoperative cholangiography (IOC); a diagnosis of PBM was established in 60 cases based on IOC alone. The diagnosis rate of pediatric PBM varied significantly among the four groups (P < 0.0001). Pair-wise comparison showed a significant difference between the groups of MRCP and CT (P < 0.0001), MRCP and US (P < 0.0001), IOC and CT (P < 0.0001), IOC and US (P < 0.0001), CT and US (P = 0.0027), and there is no significant difference between the groups of IOC and MRCP (P = 0.0502). CONCLUSION US, IOC, CT and MRCP are valuable in showing dilatation of the bile duct and complications in pediatric PBM. MRCP is non-invasive, gives clear views of the pancreaticobiliary junction and should be the first choice for the diagnosis of PBM in children.

Abstract
BACKGROUND AND OBJECTIVES Laparoscopic cholecystectomy (LC) is increasingly being used as an appropriate early treatment in patients with cholecystitis. This study evaluated the safety, effectiveness, and complications of LC in all cases of acute cholecystitis. METHODS A retrospective study involved the patients who underwent LC for acute cholecystitis within 72 hours of admission. The preoperative diagnosis was based on clinical, laboratory, and echographic examinations, while the final diagnosis was confirmed by histopathological examination of the excised gallbladder. RESULTS We identified 184 patients with acute cholecystitis. Intraoperative cholangiography (IOC) was not performed. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) was performed in 62 patients (33.7%), and postoperative ERCP in 13 patients (7.1%). Conversion to open cholecystectomy was necessary in 19 patients (10.3%); 16 patients for severe inflammation and adhesions and 3 patients because of uncontrolled bleeding. The mean operative time was 68 minutes. No deaths occurred. The overall complication rate was 6% with 3 postoperative bile leakages and 2 nonbilious subhepatic collections. The mean postoperative hospital stay was 2.8 days. CONCLUSIONS LC is a safe, effective procedure for the early management of patients with acute cholecystitis. LC can be safely performed without routine IOC when ERCP is performed preoperatively on the basis of specific indications. Meticulous dissection and good exposure of Calot's triangle may prevent bile duct injuries.

Abstract
Situs inversus totalis is an uncommon anatomic anomaly that complicates diagnosis and management of acute abdominal pain. Expedient diagnosis of common intraperitoneal disease processes such as biliary colic, acute appendicitis and diverticulitis is often delayed as a result of seemingly incongruous physical findings. We present the case of a young woman with prior emergency room visits for complaints of a vague left upper quadrant abdominal pain. An ultrasound performed on her third presentation revealed visceral situs inversus with cholelithiasis and dilated intra- and extrahepatic biliary ducts. Standard laparoscopic cholecystectomy and cholangiography with a mirror-image surgical approach was performed successfully and without complication.

Abstract
A case of bile duct injury during laparoscopic cholecystectomy finally necessitating right hepatic lobectomy is reported to re-emphasize the importance of preoperative and intraoperative assessment of the biliary tree. A 47-year-old Japanese woman underwent laparoscopic cholecystectomy for cholecystolithiasis. On postoperative day 5, fever and right hypochondralgia developed, and CT revealed fluid collection at the right hypochondrium. Percutaneous drainage was performed, and subsequent fistulography revealed a communication of the cystic cavity with the right posterior bile duct, which suggested injury of the aberrant hepatic duct. Conservative therapy, including the adaptation of fibrin glue, was performed, but closure of the fistula and cavity was not obtainable. Finally, a right hepatic lobectomy was performed four months after cholecystectomy. In this case, endoscopic retrograde cholangiopancreatography was unsuccessful preoperatively, and intraoperative cholangiography was not done. This case report re-emphasizes that the preoperative and intraoperative examination of the biliary tree is mandatory to avoid bile duct injury.
