Hypothesis
The intrahepatic technique is associated with less early biliary complications compared to the extrahepatic technique.
Conclusion
Intrahepatic hilar division is as safe as extrahepatic hilar division, but the extrahepatic technique is linked to more severe bile leaks and biliary injuries.
Supporting Evidence
- Operative time was longer in the extrahepatic group (245 ± 50 min) compared to the intrahepatic group (214 ± 38 min).
- Bile leak rates were similar between groups, but severity differed, with 70% of leaks in the intrahepatic group being grade I.
- Overall complication rates were comparable between the two techniques (55% vs 52%).
- Two patients in the intrahepatic group and one in the extrahepatic group died postoperatively.
Takeaway
Doctors compared two ways to do liver surgery and found that one way caused fewer serious problems with bile leaks.
Methodology
Retrospective analysis of 150 patients who underwent major hepatectomies, divided into intrahepatic and extrahepatic groups based on the technique used.
Potential Biases
Different surgical teams operated on the two groups, which may introduce variability in outcomes.
Limitations
The study is retrospective and may be subject to selection bias.
Participant Demographics
Mean age 63 years, 75 males and 25 females in the intrahepatic group; 38 males and 12 females in the extrahepatic group.
