Area of Science:

  • Surgical Innovation
  • Gastroenterology
  • Medical Device Technology

Background:

  • Biliary-enteric anastomosis, particularly Roux-en-Y hepaticojejunostomy, is a common procedure for biliary diversion in benign biliary strictures.
  • Internal stents are frequently used to maintain patency in these anastomoses.
  • The study explores an alternative method using an external metallic circle.

Purpose of the Study:

  • To evaluate the efficacy of an external metallic circle in maintaining the patency and stability of hepaticojejunostomy anastomoses.
  • To assess the potential of this device as an alternative to internal stents in managing benign biliary strictures.

Main Methods:

  • Hepaticojejunostomy with an external metallic circle was performed on eight male Sprague-Dawley rats.
  • Anastomoses were analyzed for patency and the stability of the external circles after three months.

  • Surgical relaparotomy was used for the assessment.

    • Main Results:

    • All hepaticojejunostomy anastomoses were found to be patent upon relaparotomy.
    • The external metallic circles remained in their original positions, demonstrating stability.
    • No complications related to the device were reported.

    Conclusions:

    • The external metallic circle is a promising alternative to internal stents for maintaining patency in hepaticojejunostomy anastomoses.
    • This method can be suitable for specific cases of benign biliary strictures requiring biliary diversion.
    • Further research may explore its application in human clinical trials.
