Summary
Permanent duct fenestration after common bile duct exploration (CBDE) significantly reduces retained stones compared to temporary T-tube decompression. This approach improves long-term outcomes for patients with bile duct lithiasis, offering better efficiency.
Area of Science:
- Gastroenterology
- Surgical Innovation
- Biliary Tract Surgery
Background:
- Retained or recurrent bile duct stones after common bile duct exploration (CBDE) remain a challenge, occurring in 5.4%–20.9% of cases.
- Functional obstruction due to sphincter of Oddi (SO) dysmotility is a suspected cause of persistent duct lithiasis.
- Permanent duct fenestration is proposed as a superior management strategy for affected bile ducts.
Purpose of the Study:
- To prospectively evaluate the short- and long-term outcomes of two surgical approaches for bile duct lithiasis following primary CBDE.
- To compare the efficacy of temporary T-tube decompression versus permanent duct fenestration in managing retained/recurrent calculi.
- To establish a benchmark for comparing new laparoscopic techniques against established surgical methods.
Main Methods:
- A prospective study comparing two groups of patients undergoing primary CBDE.
- Group A: 162 CBDEs with T-tube decompression (79 patients) or definitive drainage (83 patients).
- Group B: 80 CBDEs with permanent "fenestration" (77 patients) and minimal T-tube use (3 patients).
Main Results:
- Operative mortality rates were similar: 2.5% in Group A and 1.3% in Group B.
- Long-term results showed significantly worse outcomes with T-tube decompression: 12.7% of Group A patients required further intervention for retained/recurrent stones.
- Permanent fenestration in Group B resulted in fewer complications, with only 1.3% requiring revisional surgery for anastomotic issues.
Conclusions:
- Permanent duct fenestration is more effective for long-term management of bile duct lithiasis than temporary T-tube decompression.
- The approach used in Group B, featuring permanent fenestration, provides a superior benchmark for evaluating emerging laparoscopic techniques.
- This study highlights the importance of addressing potential SO dysmotility through definitive duct management.
