RESUMO

Objective: To analyze the clinical application value of a novel magnetic navigation ultrasound (MNU) combined with digital subtraction angiography (DSA) dual-guided percutaneous transhepatic biliary drainage (PTCD) through the right hepatic duct for the treatment of malignant obstructive jaundice. Methods: Randomized controlled trial. The clinical data of 64 patients with malignant obstructive jaundice requiring PTCD through the right hepatic duct at the Hepatobiliary Center of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Province People's Hospital) from December 2018 to December 2021 were retrospectively analyzed. The MNU group (n=32) underwent puncture guided by a novel domestic MNU combined with DSA, and the control group (n=32) underwent puncture guided by traditional DSA. The operation time, number of punctures, X-ray dose after biliary stenting as shown by DSA, patients' tolerance of the operation, success rate of the operation, pre- and post-operative total bilirubin, and incidence of postoperative complications were compared between the two groups. Results: The operation time of the MNU group was significantly shorter than that of the control group [(17.8±7.3) vs. (31.6±9.9) min, t=-6.35,P=0.001]; the number of punctures in the MNU group was significantly lower [(1.7±0.6) vs. (6.3±3.9) times, t=-6.59, P=0.001]; and the X-ray dose after biliary stenting as shown by DSA in the MNU group was lower than that in the control group [(132±88) vs. (746±187) mGy, t=-16.81,P<0.001]; Five patients in the control group were unable to tolerate the operation, and two stopped the operation, however all patients in the MNU group could tolerate the operation, and all completed the operation, with a success rate of 100% (32/32) in the MNU group compared to 93.8%(30/32) in the control group; the common complications of PTCD were biliary bleeding and infection, and the incidence of biliary bleeding (25.0%, 8/32) and infection (18.8%, 6/32) in the MNU group was significantly lower than that in the control group, 53.1% (17/32) and 28.1% (9/32), respectively. Conclusion: Magnetic navigation ultrasound combined with DSA dual-guided PTCD through the right biliary system for the treatment of malignant obstructive jaundice is safe and feasible.

RESUMO

A woman in her 30s presented to the emergency department with a month-long history of postprandial epigastric pain radiating to her back. The diagnosis of cholecystolithiasis and suspected choledocholithiasis was made, and the patient underwent cholecystectomy with cholangiography using standard technique. The surgery was complicated by an intrahepatic bile duct injury attributed to high injection pressure during cholangiography. She developed an intrahepatic collection that was drained and confirmed the diagnosis of biloma. In this case report, we discuss a rare complication of intraoperative cholangiography during laparoscopic cholecystectomy and consider a way to prevent it.

RESUMO

An asymptomatic 77-year-old man with intrahepatic bile duct dilation was referred to our hospital. Cholangiography revealed alternations between strictures and dilated segments from the right and left hepatic ducts to the lower bile ducts, with findings of a pruned tree, beaded, shaggy appearance, and diverticulum-like outpouching. Histopathology revealed abundant immunoglobulin G4 (IgG4)-positive plasma cells (> 10 per high-power field) with an IgG4/IgG-positive cell ratio of 40-50%. After 2 weeks of steroid therapy, the cholangiography markedly improved. Because the cholangiographic findings resembled those of primary sclerosing cholangitis, steroid therapy proved useful in differentiating IgG4-related sclerosing cholangitis from primary sclerosing cholangitis.

RESUMO

BACKGROUND: This study aimed to compare outcomes of standard laparoscopic cholecystectomy and indocyanine green fluorescent cholangiography laparoscopic cholecystectomy over a 10-year period. METHODS: From 2013 to 2023, 173 laparoscopic cholecystectomies were performed in 2 pediatric surgery units: 83 using standard technique (G1) and 90 using indocyanine green fluorescent cholangiography (G2). Patients included 96 girls and 77 boys, with a median age of 12.3 years (range 4-17) and a median weight of 51 kg (range 19-114). The 2 groups were compared regarding the following: (1) perioperative complications rate; (2) overall length of surgery (T1); (3) length of cystic duct isolation, clipping, and sectioning (T2); (4) time of gallbladder removal (T3); (5) degree of visualization of biliary tree; (6) safety and feasibility of indocyanine green fluorescent cholangiography; (7) incidence of anatomical anomalies detected intraoperatively. RESULTS: All laparoscopic cholecystectomies were accomplished without conversion to open. The perioperative complications rate was significantly higher in G1 compared with G2 (12% vs 0%; P = .0007). Median T1, T2, and T3 were significantly longer in G1 (90, 37, 35 minutes) compared with G2 (55, 17, 19 minutes) (P = .0001), respectively. The visualization rate of the complete biliary tree was significantly higher in G2 (98.8%) than in G1 (80.7%) (P = .0001). No adverse reactions to indocyanine green were recorded. The incidence of biliary anomalies detected intraoperatively was significantly higher in G2 (7.8%) than in G1 (1.2%) (P = .03). CONCLUSION: Indocyanine green fluorescent cholangiography can be considered the new standard practice to perform laparoscopic cholecystectomy in pediatrics. Indocyanine green fluorescence provided superior visualization of biliary anatomy, increased detection of anatomic variants, faster procedure, and fewer complications compared with conventional technique. Indocyanine green fluorescent cholangiography was safe, feasible, simple, inexpensive, and a timesaving tool.

RESUMO

AIMS: The identification of the anatomical components of the Calot's Triangle during laparoscopic cholecystectomy (LC) might be challenging and its difficulty may increase when a surgical trainee (ST) is in charge, ultimately allegedly affecting also the incidence of common bile duct injuries (CBDIs). There are various methods to help reach the critical view of safety (CVS): intraoperative cholangiogram (IOC), critical view of safety in white light (CVS-WL) and near-infrared fluorescent cholangiography (NIRF-C). The primary objective was to compare the use of these techniques to obtain the CVS during elective LC performed by ST. METHODS: This was a multicentre prospective observational study (Clinicalstrials.gov Registration number: NCT04863482). The impact of three different visualization techniques (IOC, CVS-WL, NIRF-C) on LC was analyzed. Operative time and time to achieve the CVS were considered. All the participating surgeons were also required to fill in three questionnaires at the end of the operation focusing on anatomical identification of the general task and their satisfaction. RESULTS: Twenty-nine centers participated for a total of 338 patients: 260 CVS-WL, 10 IOC and 68 NIRF-C groups. The groups did not differ in the baseline characteristics. CVS was considered achieved in all the included case. Rates were statistically higher in the NIR-C group for common hepatic and common bile duct visualization (p = 0.046; p < 0.005, respectively). There were no statistically significant differences in operative time (p = 0.089) nor in the time to achieve the CVS (p = 0.626). Three biliary duct injuries were reported: 2 in the CVS-WL and 1 in the NIR-C. Surgical workload scores were statistically lower in every domain in the NIR-C group. Subjective satisfaction was higher in the NIR-C group. There were no other statistically significant differences. CONCLUSIONS: These data showed that using NIRF-C did not prolong operative time but positively influenced the surgeon's satisfaction of the performance of LC.

RESUMO

This case report describes a laparoscopic approach using fluorescence imaging guidance to treat gangrenous cholecystitis with perforation (GCP). A male patient in his early 60s presented with 3 days of right upper abdominal pain. Computed tomography and ultrasonography findings were consistent with a stone incarcerated in the gallbladder neck, GCP, and localized peritonitis. Percutaneous gallbladder drainage was initially performed, followed by laparoscopic cholecystectomy 7 days later, using combined intravenous and intracholecystic fluorescent cholangiography. This technique allowed visualization of the cystic and common bile ducts during surgery and enabled safe removal of the diseased gallbladder. The patient recovered well without complications, and reported no pain or discomfort at a 2-month follow-up.

RESUMO

We report the case of a woman in her 40s, with no significant medical history, submitted to a laparoscopic cholecystectomy in our institution for symptomatic gallbladder lithiasis. On postoperative day 4, she presented to our emergency room with severe abdominal pain and elevated inflammatory markers. Abdominal CT scan revealed a mass filled with liquid and air in the gallbladder fossa. Surgical exploration was performed revealing a major common hepatic duct iatrogenic injury, which was managed using suture over a T-tube. Three months after surgery, cholangiography showed a biliary stenosis, and a biodegradable stent was inserted through percutaneous transhepatic access. The difficulties in the management of this condition and its outcomes are discussed in this report.

RESUMO

THE AIM OF THE STUDY: Is evaluating the possibility of integrating ICG-fluorescent cholangiography into the general safety system for laparoscopic cholecystectomy to prevent damage to the extrahepatic bile ducts by working out the methodological aspects of navigation technologies. MATERIALS AND METHODS: The analysis of literature data on various approaches to improve the perioperative identification of anatomical structures during laparoscopic cholecystectomy, including the ICG-fluorescent cholangiography, was carried out. This program was implemented during the provision of elective surgical care to 24 patients with cholelithiasis who underwent laparoscopic cholecystectomy with ICG-fluorescent navigation. RESULTS AND DISCUSSION: The developed program included: preoperative assessment of the anatomy of the biliary tree using MRCP; intraoperative technique of safe laparoscopic cholecystectomy with mandatory application of the concept of «critical view of safety¼ (CVS), which allows the most effective identification of the necessary anatomical structures; the use of ICG-fluorescent cholangiography, which allows to improve the control of anatomical structures at all stages of the operations. CONCLUSIONS: The first experience of using ICG-fluorescent cholangiography testifies to the high informative value of the method, the possibility and prospects of integrating the technology into a comprehensive safety system during laparoscopic cholecystectomy.

RESUMO

Iatrogenic bile duct injury is a rare complication, although feared due to its morbidity and mortality. In urgent surgeries, its incidence can be doubled, so in selected cases we must assess the use of resources such as indocyanine green to minimize the risk of biliary or arterial lesions by allowing the correct identification of the structures. We present the case of a 57-year-old patient with acute cholecystitis who underwent laparoscopic cholecystectomy. Given the difficulty in differentiating structures in Calot's triangle, the decision was made to use indocyanine green, which identifies a very short cystic duct, thus avoiding iatrogenic bile duct injury.


La lesión iatrogénica de vía biliar es una complicación infrecuente, aunque temida por su morbimortalidad. En cirugías urgentes, su incidencia puede duplicarse, por lo que en casos seleccionados debemos valorar la utilización de recursos como el verde de indocianina para minimizar el riesgo de lesiones biliares o arteriales, al permitir una correcta identificación de las estructuras. Presentamos el caso de una paciente de 57 años con colecistitis aguda a la que realizamos colecistectomía laparoscópica. Ante la dificultad en la diferenciación de estructuras en el triángulo de Calot, se decidió utilizar verde de indocianina, que identificó un conducto cístico muy corto, evitando así una lesión iatrogénica de vía biliar.

RESUMO

INTRODUCTION: Bile duct injuries avoidance is a key goal of biliary surgery. In this prospective study we evaluate the safety and feasibility of ICG fluorescent cholangiography during laparoscopic cholecystectomy (LC) focusing on the optimization of timing and dose administration. MATERIAL AND METHODS: From February to December 2022 fifty-four LC were performed with fluorescence imaging in our surgical department. 2.5 mg ICG were administered intravenously between 5 h and 24 h before surgery. Near-infrared fluorescent cholangiography (NIRF-C) was performed. Adequate fluorescence was evaluated by comparing agent accumulation in the gallbladder and the extrahepatic duct and the background of liver parenchyma. RESULTS: Biliary anatomy was identified in all cases. Median time of ICG administration was 11 h previous surgery and three groups of patients were identified: group A receiving ICG 5-9 h, group B 10-14 h, group C 15-24 h before surgery. Peak contrast was gained in group B, with minimal fluorescence of liver parenchyma and more intense visibility of the biliary tract. Intraoperative cholangiogram was unnecessary in all cases. CONCLUSION: Fluorescent cholangiography during LC is safe and feasible overcoming the limits of other techniques available. 2.5 mg ICG administered 10-14 h before surgery produces optimal outcomes for near-infrared (NIR) fluorescent cholangiography.

RESUMO

OBJECTIVE: To assess the predictive value of preoperative serum laboratory test results for identifying choledocholithiasis and reduce the use of cholangioresonance and its inherent costs. METHODS: Patients aged 21-69 years who underwent preoperative cholangioresonance examination at our institute were included. Patients with a history of fluctuating jaundice or biliary pancreatitis, bile duct dilatation on ultrasonography, and elevated levels of canalicular enzymes (alkaline phosphatase >100U/L and gamma-glutamyl transferase >50U/L) underwent cholangioresonance-guided surgery. Cases of choledocholithiasis confirmed by cholangioresonance were compared with those without choledocholithiasis. Serum laboratory data were evaluated and the diagnostic capabilities of these examinations were analyzed. RESULTS: A total of 104 patients were included. For detecting choledocholithiasis using alkaline phosphatase, the cut-off point was 78U/L, sensitivity was 97.6% (95%CI: 87.4-99.9), and specificity was 72.6% (95%CI: 59.8-83.1). In the binary logistic regression analysis, age (OR= 0.92; 95%CI: 0.86-0.98) and alkaline phosphatase level (OR= 1.02; 95%CI: 1.01-1.05) were selected for the final model. CONCLUSION: Serum alkaline phosphatase levels may aid preoperative diagnosis of asymptomatic choledocholithiasis. After a global clinical assessment of the patient, serum laboratory findings may contribute to a reduction in cholangioresonance-related heathcare costs.

RESUMO

BACKGROUND: Transparency around surgeon level data may align healthcare delivery with quality care for patients. Biliary surgery includes numerous procedures performed by both general surgeons and subspecialists alike. Cholecystectomy is a common surgical procedure and an optimal cohort to measure quality outcomes within a healthcare system. METHODS: Data were collected for 5084 biliary operations performed by 68 surgeons in 11 surgical divisions in a health system including a tertiary academic hospital, two regional community hospitals, and two ambulatory surgery centers. A privacy protected dashboard was developed to compare surgeon performance and cost between July 2018 and June 2022. A sample cohort of patients ≥ 18 years who underwent cholecystectomy were compared by operative time, cost, and 30-day outcomes. RESULTS: Over 4 years, 4568 cholecystectomy procedures were performed by 57 surgeons. Operations were done by 57 surgeons in four divisions and included 3846 (84.2%) laparoscopic cholecystectomies, 601 (13.2%) laparoscopic cholecystectomies with cholangiogram, and 121 (2.6%) open cholecystectomies. Patients were admitted from the emergency room in 2179 (47.7%) cases while 2389 (52.3%) cases were performed in the ambulatory setting. Individual surgeons were compared to peers for volume, intraoperative data, cost, and outcomes. Cost was lowest at ambulatory surgery centers, yet only 4.2% of elective procedures were performed at these facilities. Prepackaged kits with indocyanine green were more expensive than cholangiograms that used iodinated contrast. The rate of emergency department visits was lowest when cases were performed at ambulatory surgery centers. CONCLUSION: Data generated from clinical dashboards can inform surgeons as to how they compare to peers regarding quality metrics such as cost, time, and complications. In turn, this may guide strategies to standardize care, optimize efficiency, provide cost savings, and improve outcomes for cholecystectomy procedures. Future application of clinical dashboards can assist surgeons and administrators to define value-based care.

RESUMO

BACKGROUND: Magnetic resonance cholangiopancreatography (MRCP) provides a noninvasive and fast modality for imaging the biliary tree when choledocholithiasis is suspected. Guidelines suggest that MRCP is recommended when strong or moderate signs of common bile duct (CBD) stones are present. Well-performed prospective studies are scarce regarding the sensitivity and specificity of preoperative MRCP in patients with acute cholecystitis in comparison with intraoperative cholangiography, ERCP, or choledochoscopy. METHODS: We performed a prospective, observational population-based feasibility study in Central Finland Hospital Nova between January 2019 and December 2019. We examined the diagnostic performance of preoperative MRCP on consecutive patients with acute cholecystitis scheduled for index admission cholecystectomy. The accuracy of MRCP was verified with IOC, choledochoscopy, or ERCP. The interobserver reliability of the image quality of MRCP and the sensitivity and specificity of choledocholithiasis were observed independently by three experienced radiologists. RESULTS: A total of 180 consecutive patients diagnosed with acute cholecystitis followed by index admission cholecystectomy were identified. MRCP was performed in 113/180 (62.8%) patients, and complementary perioperative imaging of the bile ducts was performed in 72/113 (63.7%) patients. The incidence of choledocholithiasis was high (29.2%). In acute cholecystitis, the sensitivity (76.2-85.7%) and specificity (84.3-92.2%) of MRCP were equally compared to the literature with unselected patient groups. The best visibility was observed in the common hepatic duct, the inferior CBD, and the central hepatic duct. The interobserver reliability was excellent for determining the size and quantity of CBD stones. CONCLUSION: In acute cholecystitis, MRCP yields high negative predictive value regarding detection of choledocholithiasis. If CBD stones were discovered, the interobserver reliability was excellent when measuring the size and number of CBD stones. The best-visualized area was the distal part of the biliary tract, which provides good preoperative workup if choledocholithiasis is present.

RESUMO

The 'Basket-in-Catheter' (BIC) technique facilitates basket-only laparoscopic transcystic exploration (LTCE), increasing its success rate. Using the cholangiography catheter as a sheath is easier and safer than inserting the wire basket-alone. This study evaluates its benefits in confirmed and suspected ductal stones. Retrospective analysis of prospectively collected data on patients with pre-operative or operative suspicion of bile duct stones or with positive and equivocal intraoperative cholangiographies (IOC) who had LTCE attempted using blind basket trawling, without choledochoscopy, were reviewed. The incidence and outcomes of blind basket LTCEs attempted before and after introducing the BIC technique, whether or not stones were retrieved, were analysed. Blind basket LTCE was attempted in 732 patients. Of 377 (51.5%) patients undergoing successful stone retrieval, only 62% had pre-operative clinical and radiological risk factors for ductal stones, 25% had operative risk factors and 13% had silent stones discovered on IOC. Another 355 patients (48.5%) had negative trawling, although one half had pre-operative risk factors for ductal stones and 47.6% had operative risk factors, e.g. cystic duct stones or dilatation. This cohort had equivocal cholangiography in 25.9%. Following basket trawling, repeat IOC confirmed resolution of abnormalities. As no stones were retrieved, these were not considered duct explorations. The BIC technique facilitates safe and speedy bile duct clearance when stones are confirmed, avoiding choledochotomies, without significant complications. BIC duct trawling is also beneficial in patients with suspected ductal stones, helping to resolve equivocal IOCs. It helps surgeons to acquire and consolidate ductal exploration skills.
