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.

To circumvent the difficulty in completing the anastomosis of the pancreatic duct and jejunal mucosa under laparoscopy for patients with a small pancreatic duct and soft and fragile pancreatic tissue, we introduce a reverse needle continuous suture technique for laparoscopic pancreaticojejunostomy of the pancreatic duct and jejunal mucosa.

A protocol for the cannulation of the mouse submandibular salivary gland via the Wharton's duct is described. For this experiment, the trypan blue solution is used as a dyer to demonstrate how this technique effectively delivers infusions into the targeted gland, and to suggest the reliability of this new approach as a potential clinical drug/cell therapy for the regeneration of salivary glands.

FAQs
Precise alignment of the duct opening with the recipient mucosa supports a continuous drainage route. If the edges do not meet appropriately, the intended passage for secretions may be compromised, increasing concern about leakage or obstruction during healing. This makes geometric apposition a central technical principle when researchers assess reconstruction after tissue removal or injury.
Fine sutures provide the physical support needed to secure the duct edge against the recipient mucosa. Their purpose is not simply to hold tissue together; secure edge fixation helps preserve the intended drainage connection while limiting escape of secretions from the anastomosis. This relationship explains why suture security is relevant when evaluating leakage risk after reconstruction.
Leakage and obstruction represent different ways the reconstructed pathway can fail. Leakage concerns containment at the connection, whereas obstruction concerns the ability of secretions to pass through it. Tracking both provides a more informative assessment than treating healing as a single outcome, because a closed connection may still have impaired drainage.
A basic reconstruction workflow includes exposing the cut end of the duct, positioning it against the mucosal lining of the recipient organ, aligning the openings, and securing the apposed edges with fine sutures. The intended result is a controlled route for secretions with limited leakage. This sequence provides a framework for describing and comparing surgical treatment strategies.
After tumor resection involving the pancreas or biliary tract, this reconstruction can restore drainage disrupted by tissue removal. Its relevance extends beyond technical completion: postoperative healing, leakage, and obstruction can influence recovery. Cancer research therefore considers the anastomosis when evaluating how surgical treatment strategies affect outcomes after operations involving these organs.
Researchers can examine whether a surgical strategy preserves drainage while maintaining a stable connection during healing. Key observations include the quality of edge apposition, evidence of leakage, and signs of obstruction. Together, these outcomes help connect the technical features of reconstruction with postoperative performance in studies of pancreatic or biliary tract tumor resection.
