Abstract Background Laparoscopic cholecystectomy (LC) is increasingly being used as a first-line treatment for acute cholecystitis. Bile duct injury (BDI) remains the most feared complication of the minimally invasive approach specially in cases with an inflamed calots triangle. While use of indocyanine dye (ICG) to delineate biliary anatomy serves to reduce BDI, the high cost of the technology prohibits its use in the developing world. We propose a novel use of common bile duct (CBD) stenting preoperatively in cases of cholecystitis secondary to choledocholithiasis as a means of identification and safeguarding the CBD. Methods A retrospective review was conducted on 22 patients of Grade 2 or Grade 3 cholecystitis who underwent an early LC at our institution. All patients were stented preoperatively and the stent was used for a much-needed tactile feedback during dissection. A c-arm with intraoperative fluoroscopy was used to identify the CBD prior to clipping of the cystic duct. Results The gall bladder was gangrenous in all the cases while two cases had evidence of end organ damage. This innovative use of CBD stenting allowed us to correctly delineate biliary anatomy in all of the cases and we report no instances of BDI despite a severely inflamed local environment. Conclusion This technique can become a standard of care in all teaching institutions in developing countries further enhancing the safety of cholecystectomy in gangrenous cholecystitis with a distorted biliary anatomy.

Abstract Background Normal biliary anatomy is uncommon. Different classification for biliary anatomy has been described, with Huang Types A4 & A5 of great interest for laparoscopic cholecystectomy (LC) due to the proximity of aberrant bile duct to Cystic duct (CD). These types of dangerous anatomy might contribute to bile duct injury. This study aims to analyse the prevalence of dangerous biliary anatomy. Methods Prospectively collected data for all patients who underwent laparoscopic cholecystectomy was analysed. All LC were performed by single surgeon or under  his direct supervision, between 01/07/2020 and 20/08/2021. Index admission and single session management of cholelithiasis disease with routine Laparoscopic cholecystectomy + intra operative cholangiography (IOC) +/- LCBD exploration were standard practice. Results Laparoscopic cholecystectomy was performed in 137 patients. Mean age was 56y (17-84).  62% were females.   66% of Laparoscopic cholecystectomies were emergency. IOC was performed in 92% of cases. Abnormal biliary anatomy was found in 54% : Huang A1 - 48%, A2 - 29%, A3 - 12%, A4 - 9.7% and A5 - 0.7%. Dangerous anatomy (A4 and A5) was found in 10.5%, 78 % were females.  Female with dangerous anatomy were younger than males 49 y, 60y respectively. Nassar difficulty grading for dangerous anatomy was as follows: G2 28%, G3 42% and G3 28% Abnormal cholangiogram was found in 48%, due to filling defect in 58%, no contrast flow into duodenum in 4%, Cystic duct stone in 4%, and short CD in 8%. CBD stones were treated using transcystic approach in 92% of cases. No intra-operative or post operative complications were recorded for patients with dangerous anatomy.  Conclusions This study demonstrates that dangerous biliary anatomy, that could lead to bile duct injury is relatively common, occurring in 10.7% of LCs. Routine intra-operative cholangiography highlights these high-risk variations in biliary anatomy and may prevent inadvertent bile duct injury in such cases.

Endoscopic surgery, which was first introduced in the late 1980s, has rapidly become widespread. However, despite its popularity, the occurrence of intraoperative organ damage has not necessarily decreased. To avoid intraoperative bile duct injury in laparoscopic cholecystectomy, which is one of the most popular procedures in endoscopic surgery, we are developing a laparoscopic surgical system that uses Artificial Intelligence (AI) to identify four anatomical landmarks (cystic duct of the gallbladder, common bile duct, lower surface of hepatic S4, and Rouviere’s sulcus, related to “Calot’s triangle") in real time during surgery. The development process consists of 5 steps: 1) identification of anatomical landmarks, 2) collection and creation of teaching data, 3) annotation and deep learning, 4) validation of development model, and 5) actual clinical performance evaluation. At present, anatomical landmarks can be identified with high accuracy in an actual clinical performance test in laparoscopic cholecystectomy, whereas issues for practical clinical use, such as a need to recognize the scene of surgical steps and surgical difficulties related to inflammation of the gallbladder, have also been clarified. The development of an AI-navigation system for endoscopic surgery, which could identify anatomical landmarks in real time during surgery, could be expected to support surgeons' decisions, reduce surgical complications, and contribute to improving the quality of surgical treatments.

Iatrogenic Bile Duct Injury

Although laparoscopic cholecystectomy (LC) has been widely accepted as the standard of care, it continues to have a higher complication rate than open cholecystectomy. Bile duct injury with LC has often been attributed to surgical inexperience, but it is also clear that aberrant bile ducts are present in a significant number of patients who sustain biliary injuries during these procedures. We present three cases of right sectoral hepatic duct injuries which occurred during LC and provide a discussion of the conditions which are likely to lead to these injuries, as part of a strategy to prevent them.

Iatrogenic Bile Duct Injury

Abstract​ Laparoscopic cholecystectomy (LC) is one of the most frequently performed surgical procedures worldwide. Iatrogenic bile duct injury (IBDI) is a serious complication of LC and has an incidence of 0.3 to 0.7%. Since it is associated with a significant and potentially lifelong morbidity as well as mortality, diagnosing IBDI as early as possible is of paramount importance. Management of bile duct injuries and prognosis of their surgical repair depend on the timing of its recognition, type and the extent of the injury. In this paper, we present a case of IBDI and attempt to discuss all its dimensions.

Iatrogenic Bile Duct Injury

AbstractIatrogenic bile duct injuries (BDI) are still a challenging diagnostic and therapeutic problem. With the introduction of the laparoscopic technique for the treatment of cholecystolithiasis, the incidence of iatrogenic BDI increased.was a retrospective analysis of 69 patients treated at the department due to iatrogenic BDI in the years 2004-2014.. In this paper, we presented the results of a retrospective analysis of 69 patients treated at the Department due to iatrogenic BDI in the years 2004-2014. The data were analysed in terms of age, sex, type of biliary injury, clinical symptoms, the type of repair surgery, the time between the primary surgery and the BDI management, postoperative complications and duration of hospital stay.. 82.6% of BDI occurred during laparoscopic cholecystectomy, 8.7% occurred during open cholecystectomy, whereas 6 cases of BDI resulted from surgeries conducted for other indications. In order to assess the degree of BDI, Bismuth and Neuhaus classifications were used (for open and laparoscopic cholecystectomy respectively). 84.1% of patients with confirmed BDI, were transferred to the Department from other hospitals. The average time between the primary surgery and reoperation was 6.2 days (SD 4). The most common clinical symptom was biliary fistula observed in 78.3% of patients. In 28 patients, unsuccessful attempts to manage BDI were made prior to the admission to the Department in other centres. The repair procedure was mainly conducted by laparotomy (82.6%) and by the endoscopic approach (15.9%). Hepaticojejunostomy was the most common type of reconstruction following BDI (34.7%).. The increase in the rate of iatrogenic bile duct injury remains a challenging surgical problem. The management of BDI should be multidisciplinary treatment. Referring patients with both suspected and confirmed iatrogenic BDI to tertiary centres allows more effective treatment to be implemented.

Eosinophilic cholangiopathy is termed as a rare, benign, and self-limiting disease. Moreover, the interference of malignant tumor to diagnosis and the changing process of disease make the accurate treatment proposal challenging. A significant number of patients require surgery for the definitive diagnosis and resolution of symptoms. We put forward a case of eosinophilic cholangiopathy infiltrating the gallbladder and bile duct with bone marrow involved, coupled with peripheral eosinophilia. The patient underwent a successful treatment using laparoscopic cholecystectomy and steroids, instead of extrahepatic bile duct excision with Roux-en-Y hepaticojejunostomy. The patient gets an accurate treatment in a minimally invasive manner. In conclusion, surgery refers to not only a diagnostic methodology but also a treatment. When the bile duct and gallbladder are involved at the same time, and cannot distinguish benign and malignant diseases, laparoscopic cholecystectomy is feasible, the effect is the same, and the symptoms of eosinophilic cholecystitis are relieved.
