[ESTIMATION OF FORMATION OF HEPATICOJEJUNOANASTOMOSES, USING METHOD OF THE HF-ELECTRIC WELDING OF BIOLOGICAL TISSUES]

Area of Science:

• Gastroenterology and Hepatobiliary Surgery
• Minimally Invasive Surgical Techniques
• Biliary Tract Surgery

Background:

• Bile outflow disorders, including strictures and iatrogenic injuries, pose significant surgical challenges.
• Malignant tumors in the periampullary region often necessitate complex biliary reconstruction.
• Current surgical methods for hepaticojejunoanastomosis (HJA) may have limitations in terms of hermeticity and postoperative complications.

Purpose of the Study:

• To evaluate the efficacy and safety of HF-electric welding for creating hepaticojejunoanastomosis (HJA).
• To assess the outcomes of HF-electric welding in patients with various complex biliary conditions.

Main Methods:

• Hepaticojejunoanastomosis (HJA) was performed using HF-electric welding in 14 patients.
• The study included patients with common hepatic duct stricture, HJA stricture, purulent cholangitis, iatrogenic biliary duct injury, and periampullary tumors.
• One-layer termino-lateral or latero-lateral HJAs were created using the welding technique.

Main Results:

• Welding anastomoses were consistently hermetic and robust immediately after formation.
• The HF-electric welding method demonstrated favorable clinic-laboratory postoperative indices compared to conventional methods.
• No significant complications related to the welding technique were reported in the study group.

Conclusions:

• HF-electric welding is a safe and effective method for hepaticojejunoanastomosis (HJA) in complex biliary reconstructions.
• This technique offers advantages in achieving hermetic and durable anastomoses, potentially improving patient outcomes.
• Further research is warranted to explore long-term results and broader applications of HF-electric welding in biliary surgery.
