Disruption of bile flow results in severe inflammatory cholestatic liver injury with a characteristic time-dependent sequence of morphological alterations. Here we present a protocol for the surgical ligation of the common bile duct in mice that allows to induce a strong fibrotic response after 21 to 28 days.

A method of visualizing and quantifying the 3-dimensional structure of mouse hepatic portal vein or intrahepatic bile duct is described. This resin cast technique can also be applied to other ductal or vascular systems and allows for in situ visualization or quantification of a system's intact communicating architecture.

Cholecystolithiasis with common bile duct stones is a common disease; however, traditional common bile duct exploration has its own limitations. We propose a modified micro incision for laparoscopic common bile duct exploration aimed at reducing complication rates.

Intraoperative video consultation expedites and improves surgical care. Here, we present a case where intraoperative video consultation between a rural hospital and an academic hepatobiliary surgeon facilitated immediate diagnosis of bile duct transection during laparoscopic cholecystectomy, direct to operating room transfer between centers, and injury repair with robotic-assisted Roux-en-Y hepaticojejunostomy.

This protocol describes the production of a mouse extrahepatic bile duct 3-dimensional organoid system. These biliary organoids can be maintained in culture to study cholangiocyte biology. Biliary organoids express markers of both progenitor and biliary cells and are composed of polarized epithelial cells.
FAQs
Controlled hypothermia lowers cellular metabolic activity during the interval when the bile duct lacks normal blood flow. By slowing metabolism, it reduces the tissue’s demand for resources and helps limit ischemic damage while the organ is stored and transported. This protection is important because the biliary epithelium must remain viable until circulation is restored after transplantation.
Specialized preservation solutions complement cooling by supporting the tissue during storage. Their role is not simply to keep the organ cold: they are part of a preservation environment designed to maintain biliary tissue structure and function and reduce injury to the epithelium. Selecting and applying an appropriate solution therefore contributes to the effectiveness of the overall protocol.
The biliary epithelium is a key preservation target because its viability contributes to the duct’s ability to retain structure and function after blood flow returns. If preservation is ineffective, biliary injury may be reflected in complications such as strictures or leakage. Protecting epithelial viability therefore connects cellular preservation during storage with outcomes after transplantation.
A preservation protocol must address the entire interval between organ storage and restored circulation. The relevant sequence includes storage, transport, and transplantation, with controlled hypothermia and a specialized solution used to limit damage during that period. Keeping these conditions consistent helps preserve biliary tissue until the graft receives blood flow again.
Pretransplant strategies can extend preservation beyond passive storage by assessing bile duct function or supporting its restoration before transplantation. These approaches provide information about whether the biliary system remains functional after storage and may help evaluate preservation success before blood flow is reestablished in the recipient.
In biology and transplantation research, the topic provides a model for studying how controlled temperature and preservation solutions influence tissue viability during ischemic storage. It also supports efforts to improve liver transplantation protocols by linking preservation conditions with later biliary complications, especially strictures and leakage. This connection helps researchers evaluate whether a protocol protects both biliary structure and function.
