Preoperative percutaneous transhepatic internal drainage in obstructive jaundice: a randomized, controlled trial...

Area of Science:

• Gastroenterology and Hepatology
• Nephrology
• Surgical Oncology

Background:

• Obstructive jaundice presents significant surgical risks.
• Elevated bilirubin levels can impact renal function.
• Timing of surgical intervention is critical.

Purpose of the Study:

• To evaluate the impact of preoperative percutaneous transhepatic biliary drainage (PTBD) on surgical complications and renal function in patients with obstructive jaundice.
• To compare immediate surgery versus delayed surgery following PTBD.

Main Methods:

• Randomized controlled trial involving 30 patients with obstructive jaundice (bilirubin > 200 mumol/L).
• Patients were randomized to immediate surgery or delayed surgery after PTBD.
• Renal function was assessed using plasma urea, B 2-microglobulin, phosphate clearance, uric acid clearance, and maximal concentrating ability.

Main Results:

• Patients undergoing preoperative PTBD experienced fewer surgical complications compared to immediate surgery (p < 0.02).
• Immediate surgery led to greater renal function deterioration than PTBD or delayed surgery.
• PTBD improved phosphate clearance, indicating better tubular function, which was sustained with delayed surgery.

Conclusions:

• Preoperative PTBD can reduce surgical morbidity and renal impairment in obstructive jaundice.
• The benefits of PTBD must be weighed against its own procedural morbidity.
• PTBD may not be widely adopted due to its complication rates.
